A Review Of Robotic World Models For Dynamic Environments Based On Factor And Scene Graphs

基于因子图和场景图的动态环境机器人世界模型综述
Giberna, Marco, Fernandez-Cortizas, Miguel, Lopez, Jose Luis Sanchez, Voos, Holger
Abstract
Models based on graphs have emerged in robotics as a powerful foundation for internal world representations, where factor and scene graphs are among the most prominent model types found in the related literature and in successful robotic solutions. Initially, many of these models were assuming static environments as a simplification. Herein, factor graphs mainly provide uncertainty-aware geometric estimations while scene graphs enable a structured semantic abstraction. However, real-world robotic environments are often dynamic, posing severe challenges for purely static world representations. Therefore, this review presents a comprehensive view on how dynamic aspects of real-world environments can be addressed in such graph-based world models. We organize our assessments around three main aspects: (I) suitable representations, (II) pipelines to construct and update the representations, and (III) their exploitation for downstream tasks. We review approaches that are either based on factor or scene graphs, but put special emphasis on novel approaches that combine both types to form hybrid models. We mainly analyze how different types of dynamics can be modeled herein, and categorize common architectural patterns. Finally, emerging trends and open challenges are identified, including uncertainty propagation from learned perception through the representation layers, the observability of dynamic-entity motion and scale under minimal sensing, scalable lifelong maintenance, and the lack of datasets and evaluation protocols that ground world-model quality in downstream task performance under dynamics.

基于图的模型在机器人领域中作为内部世界表征的强大基础而出现,其中因子图和场景图是相关文献和成功机器人解决方案中最突出的模型类型。最初,许多这些模型假设环境是静态的,以简化问题。在此,因子图主要提供对不确定性的几何估计,而场景图则实现结构化的语义抽象。然而,现实世界中的机器人环境往往是动态的,这对纯静态世界表征提出了严峻的挑战。因此,本综述全面探讨了如何在此类基于图的世界模型中处理现实环境的动态特征。我们围绕三个主要方面组织评估:(I)合适的表征,(II)构建和更新表征的流程,以及(III)它们在下游任务中的应用。我们回顾了基于因子图或场景图的方法,但特别强调了将两种类型结合形成混合模型的新方法。我们主要分析了如何在此处建模不同类型的动态,并对常见的架构模式进行了分类。最后,识别出新兴趋势和开放挑战,包括从学习的感知通过表征层的不确定性传播、在最小感知下动态实体运动和尺度的可观测性、可扩展的终身维护,以及缺乏能够在动态下基于下游任务性能评估世界模型质量的数据集和评估协议。

SAFE: Unified Slip and Fracture Detection with Low-Cost Acoustic Sensing in Robotic Grasping

SAFE:在机器人抓取中利用低成本声学传感实现统一的滑动和断裂检测
Wang, Zerun, Kamat, Vivek, Bhansali, Shekhar
Abstract
Manipulating fragile objects remains challenging as robots must understand the state of what they grasp, such as slip or fracture, to respond appropriately, especially when material properties are unknown. In this paper, we present SAFE: a low-cost, general-purpose sensing approach that detects both slip and fracture in real time using two passive polyvinylidene fluoride (PVDF) acoustic sensors and motor proprioception, without relying on vision or prior material knowledge. The sensors are mounted on a compliant Fin Ray gripper, and a unified HistGradientBoosting classifier reports the state (normal, slip, or fracture) from a 79-dimensional feature vector. Under leave-one-grasp-out cross-validation, SAFE achieves an Alert-F1 of 0.884 with near-zero slip-fracture confusion, and ablations confirm that acoustic sensing is indispensable. An adaptive grasp controller built on this detection layer runs at 104 Hz on a Jetson Orin Nano, achieving 91.3% success across 46 closed-loop robot trials spanning diverse object categories, while each fixed-force strategy drops to 0% on object conditions that mismatch its preset. It further reaches 82.4% success on novel objects unseen during training, demonstrating robust, failure-aware grasp control without object-specific calibration.

操控易碎物体仍然具有挑战性,因为机器人必须理解其抓取物体的状态,例如滑动或断裂,以便做出适当反应,特别是在材料特性未知的情况下。本文提出了SAFE:一种低成本、通用的传感方法,利用两个被动聚偏二氟乙烯(PVDF)声学传感器和电机本体感知实时检测滑动和断裂,而无需依赖视觉或先前的材料知识。传感器安装在一个柔性Fin Ray夹持器上,统一的HistGradientBoosting分类器根据79维特征向量报告状态(正常、滑动或断裂)。在留一抓取交叉验证下,SAFE实现了0.884的Alert-F1,几乎没有滑动与断裂的混淆,消融实验确认声学传感是不可或缺的。基于这一检测层构建的自适应抓取控制器在Jetson Orin Nano上以104 Hz的频率运行,在46次涵盖多种物体类别的闭环机器人试验中实现了91.3%的成功率,而每种固定力策略在与其预设不匹配的物体条件下成功率降至0%。它在训练期间未见过的新物体上进一步达到了82.4%的成功率,展示了强大的、具备故障意识的抓取控制能力,而无需针对特定物体的校准。

Context-Aware Adaptive Pesticide Spraying for Agricultural Robots under Changing Weather and Terrain Using Vision-Language Models

基于视觉-语言模型的农业机器人在变化天气和地形下的上下文感知自适应喷 pesticide 喷洒
Vu, Cong-Thanh, Liu, Yen-Chen
Abstract
Precision pesticide spraying is essential for optimizing application efficiency and ensuring uniform chemical distribution. Spraying performance is influenced by multiple factors, including environmental conditions such as temperature and wind speed, pesticide type, and the robot's capability to accurately perceive crops and target spray locations. Existing approaches predominantly emphasize crop detection and rely on predefined spraying parameters, whereas human operators dynamically adjust their spraying strategies by considering environmental conditions, region-specific crop characteristics, and the type of pesticide being applied. In this study, we propose a context-aware adaptive spraying framework based on Vision-Language Models (VLMs), which enables robots to leverage spatial reasoning and integrate information from multiple sources, including crop type, pesticide type, and weather data, to make adaptive and optimized spraying decisions. Subsequently, a trajectory-tracking controller based on Model Predictive Path Integral (MPPI) control is employed to ensure precise navigation and accurate spraying at crop locations. The comparative results demonstrate that the proposed method improves accuracy by at least 30% in detecting crop rows. In addition, the experimental evaluations conducted in two environments further demonstrate the robot's ability to flexibly adjust spraying volume and travel speed, while reducing pesticide drift.

精准的 pesticide 喷洒对于优化应用效率和确保化学品均匀分布至关重要。喷洒性能受到多种因素的影响,包括温度和风速等环境条件、 pesticide 类型以及机器人准确感知作物和目标喷洒位置的能力。现有的方法主要强调作物检测,并依赖于预定义的喷洒参数,而人类操作员则通过考虑环境条件、特定区域的作物特性和所施用 pesticide 的类型,动态调整喷洒策略。在本研究中,我们提出了一种基于视觉-语言模型(Vision-Language Models, VLMs)的上下文感知自适应喷洒框架,使机器人能够利用空间推理,并整合来自多种来源的信息,包括作物类型、 pesticide 类型和天气数据,以做出自适应和优化的喷洒决策。随后,采用基于模型预测路径积分(Model Predictive Path Integral, MPPI)控制的轨迹跟踪控制器,以确保在作物位置的精确导航和准确喷洒。比较结果表明,所提方法在检测作物行方面提高了至少 30% 的准确性。此外,在两个环境中进行的实验评估进一步证明了机器人灵活调整喷洒量和行驶速度的能力,同时减少了 pesticide 漂移。

Taming an End-to-End Autonomous Driving Policy for Urban Navigation of Quadruped Robots

驯化端到端自主驾驶策略以实现四足机器人在城市导航中的应用
Kim, Joochan, Yang, Chanuk, You, Tackgeun, Wang, Ziran, Lim, Hwasup
Abstract
We present Go2-DrivoR, a goal-conditioned adaptation of the end-to-end autonomous driving trajectory planning framework DrivoR for urban navigation with quadrupedal robots. By conditioning trajectory generation on a local-frame subgoal through a goal token and adapting the vehicle-centric scoring formulation, the method extends DrivoR to short-horizon goal-conditioned local planning without redesigning its core decoders. Specifically, we redefine drivable-area compliance for sidewalk-oriented navigation and reformulate the original ego progress term as goal-conditioned ego progress. Trained exclusively on TartanGround simulation data, Go2-DrivoR improves waypoint-conditioned planning performance on unseen simulation environments and transfers zero-shot to open-loop real-world trajectory prediction.

我们提出了Go2-DrivoR,这是一个基于目标条件的适应性框架,将端到端自主驾驶轨迹规划框架DrivoR应用于四足机器人在城市导航中的任务。通过通过目标标记对局部框架子目标进行条件化轨迹生成,并调整以车辆为中心的评分公式,该方法扩展了DrivoR,使其能够在不重新设计核心解码器的情况下进行短期目标条件的局部规划。具体而言,我们重新定义了适合人行道导航的可行驶区域合规性,并将原始自我进展项重新公式化为目标条件的自我进展。在仅使用TartanGround仿真数据进行训练的情况下,Go2-DrivoR在未见过的仿真环境中提高了基于航点的规划性能,并实现了零样本转移到开放环路的真实世界轨迹预测。

Autonomous Droplet Navigation via Model-Based Reinforcement Learning: Zero-Shot Transfer and Emergent Dynamics

基于模型的强化学习实现自主液滴导航:零样本迁移与涌现动力学
Anand, Rajneesh, Kothare, Mayuresh V.
Abstract
Self-driving laboratories (SDLs) are transforming chemical and materials discovery through closed-loop automation, yet automated infrastructure for physical manipulation of soft, deformable matter remains beyond current robotic platforms. A critical instance is autonomous droplet transport on an open surface, where contact-angle hysteresis, capillary pinning, and surface heterogeneity produce partially observable dynamics that pose significant challenges for classical model-based controllers. We introduce the first robotic platform for closed-loop autonomous liquid droplet navigation on an open, unconfined surface using model-based reinforcement learning. A two-axis tilting board coated with a thin silicone oil film drives the droplet, while an overhead camera provides real-time feedback. A learned policy was trained on just 50 to 150 physical episodes depending on geometric complexity, without simulation or analytical models. Beyond performance alone, the platform demonstrates three capabilities of interest to the SDL community: it robustly transfers zero-shot to unseen geometries; it autonomously discovers an oscillatory depinning strategy to free the droplet when it sticks; and it completes its full training pipeline in under 90 minutes. These results extend reinforcement-learning manipulation from rigid microrobots to deformable soft-matter systems for next-generation SDLs.

自驱动实验室(SDL)通过闭环自动化正在改变化学和材料的发现,然而,针对软性可变形物质的物理操作的自动化基础设施仍超出当前机器人平台的能力。一种关键情况是开放表面上的自主液滴运输,其中接触角滞后、毛细钉扎和表面异质性产生部分可观测的动态,这对经典的基于模型的控制器构成了重大挑战。我们介绍了第一个用于开放、无约束表面上闭环自主液滴导航的机器人平台,该平台采用基于模型的强化学习。一个涂有薄硅油膜的双轴倾斜板驱动液滴,而一个悬挂摄像头提供实时反馈。学习策略的训练仅依赖于50到150个物理实验,具体数量取决于几何复杂性,且没有使用仿真或解析模型。除了性能本身,该平台还展示了三个对SDL社区感兴趣的能力:它能够稳健地实现零样本迁移到未见几何形状;它自主发现了一种振荡去钉策略,以在液滴粘附时将其释放;并且它在90分钟内完成了整个训练流程。这些结果将强化学习操作从刚性微型机器人扩展到可变形软物质系统,为下一代SDL提供了新的可能性。

CIRRA: Dual-Level Continual Instruction Reconciliation with Ongoing Execution for Embodied Robot Agents in Interactive Household Tasks

CIRRA:面向交互式家庭任务的具身机器人代理的双层持续指令调和与持续执行
Zhang, Ci, Nan, Enfu, Akbari, Arman, Zhao, Lin, Wang, Li, Wang, Chen, Chen, Weiwei, Wang, Yanzhi, Yuan, Geng
Abstract
Household robots must accommodate new user instructions while executing ongoing tasks. Existing agents often regenerate or extensively revise the remaining task sequence, introducing plan ambiguity, logical inconsistency, and redundant execution. We formulate continual instruction reconciliation and propose CIRRA (Continual Instruction Reconciliation for Robot Agents), a dual-level framework combining LLM-based semantic reasoning with rule-constrained structural integration. CIRRA first grounds incoming instructions to unique executable skills and resolves underspecified actions and execution locations. It then preserves the ongoing subtask sequence as an execution backbone and generates integration candidates by inserting incoming subtasks into location-matched segments. The semantic reasoner evaluates only modified segments to identify dependencies and conflicts and select the most logically coherent local integration. This structure-preserving process maintains alignment with ongoing execution, mitigates ambiguity and inconsistency, and reuses shared subtasks to reduce redundant execution. We also introduce CHIRP (Continual Household Instruction Reconciliation and Planning), a text-based benchmark of 120 episodes across eight household environments and six categories of everyday activities. On CHIRP, CIRRA achieves 74.2% decision agreement, exceeding the strongest replanning baseline by 30 percentage points; every correct fusion decision yields a correctly placed, conflict-free schedule. On a Unitree G1 humanoid, CIRRA interrupts ongoing skills at the correct moment in every trial and significantly outperforms all baselines on every metric.

家庭机器人必须在执行正在进行的任务时适应新的用户指令。现有的代理通常会重新生成或大幅修订剩余的任务序列,从而引入计划模糊性、逻辑不一致性和冗余执行。我们提出了持续指令调和的概念,并提出了CIRRA(持续指令调和机器人代理),这是一个双层框架,结合了基于大型语言模型(LLM)的语义推理与规则约束的结构整合。CIRRA首先将传入的指令与独特的可执行技能进行关联,并解决不明确的动作和执行位置。然后,它将正在进行的子任务序列作为执行主干,并通过将传入的子任务插入位置匹配的段落来生成整合候选项。语义推理器仅评估修改过的段落,以识别依赖关系和冲突,并选择最具逻辑一致性的局部整合。这个保持结构的过程与正在进行的执行保持一致,减轻了模糊性和不一致性,并重用共享子任务以减少冗余执行。我们还引入了CHIRP(持续家庭指令调和与规划),这是一个涵盖八个家庭环境和六类日常活动的120集文本基准。在CHIRP上,CIRRA实现了74.2%的决策一致性,超过了最强重规划基线30个百分点;每一个正确的融合决策都产生了一个正确放置且无冲突的时间表。在Unitree G1人形机器人上,CIRRA在每次试验中都能在正确的时刻中断正在进行的技能,并在每个指标上显著优于所有基线。

Trajectory Planning without Trajectory Data: A Manifold-Guided Approach

无需轨迹数据的轨迹规划:一种流形引导的方法
Yong, Silong, Liu, Anji, Dai, Cunxi, Busart, Carl, Shi, Guanya, Du, Yilun, Sycara, Katia, Xie, Yaqi
Abstract
A common way for trajectory planning is to leverage generative models trained on large collections of expert trajectories. At inference time, the model generates executable trajectories by conditioning on task goal constraints. However, trajectory-based methods rely on costly supervision, scale poorly with sequence length, and often generalize poorly to unseen constraints such as novel start-goal pairs. We propose an alternative to learn the underlying state-space manifold and use the geometry of the manifold for trajectory planning. This approach requires only state observations and enables generalization to unseen constraints by con- structing trajectories on the learned manifold of the state space. Experiments on Maze2D and robotic motion-planning benchmarks show that Ariadne constructs feasible paths from state-only supervision and generalizes to unseen start-goal combinations. On high-dimensional dual-arm planning, it remains competitive with trajectory-supervised and classical planners, while requiring no trajectory data for training.

轨迹规划的常见方法是利用在大量专家轨迹上训练的生成模型。在推理时,该模型通过对任务目标约束进行条件化生成可执行的轨迹。然而,基于轨迹的方法依赖于昂贵的监督,随着序列长度的增加而扩展性差,并且通常对未见约束(如新颖的起始-目标对)泛化能力较差。我们提出了一种替代方法,通过学习潜在的状态空间流形,并利用流形的几何特性进行轨迹规划。这种方法仅需状态观测,并通过在学习到的状态空间流形上构建轨迹来实现对未见约束的泛化。在Maze2D和机器人运动规划基准上的实验表明,Ariadne能够仅通过状态监督构建可行路径,并对未见的起始-目标组合进行泛化。在高维双臂规划中,它在与轨迹监督和经典规划器的竞争中表现出色,同时在训练中不需要轨迹数据。

From Wearable Interfaces to Dexterous Policies: Contact Shifts and Tactile Representations

从可穿戴接口到灵巧策略:接触变化与触觉表征
Tian, Ruitong, Xu, Fang, Wilson, Noah B., Li, Xianyao, Du, Eric Jing
Abstract
Unlike conventional teleoperation, wearable interfaces allow operators to collect dexterous demonstrations through their own hand motions while directly interacting with task objects. This direct interaction reduces dependence on the target robot during collection, but it also makes the collection hardware part of the physical process that generates each demonstration. Interface geometry can influence both how a task is performed and what tactile observations are recorded for learning. We study two versions of a DexUMI-family exoskeleton that share the same robot command definition, mapping procedure, and tactile module type but differ in hand-side geometry. The revised interface reduces reported physical demand, improves selected device ratings, enables tactile access in a precision grasp that is mechanically blocked by the baseline, and produces task-dependent changes in recorded contact. Lid twisting primarily exhibits a change in contact location, whereas egg carton opening primarily exhibits a change in contact occurrence. We then train matched policies using either a binary aggregate input or a spatial-plus-force input. On lid twisting and egg carton opening, policies trained on revised-interface demonstrations achieve higher success than those trained on baseline demonstrations, with a significant pooled interface effect. Across these and two additional tasks, USB insertion and soldering tool pick and place, the spatial-plus-force input likewise outperforms binary aggregation. These results show that wearable collection hardware is part of the data-generation process for robot learning. Such interfaces should therefore be evaluated not only through operator experience, but also through the tactile interactions they make recordable and the policy performance their demonstrations support.

与传统的遥操作不同,可穿戴接口允许操作员通过自身的手部动作在直接与任务对象互动的同时收集灵巧演示。这种直接互动减少了在收集过程中的对目标机器人的依赖,但也使得收集硬件成为生成每个演示的物理过程的一部分。接口几何形状可以影响任务的执行方式以及为学习记录的触觉观察。我们研究了两种版本的DexUMI系列外骨骼,它们共享相同的机器人命令定义、映射过程和触觉模块类型,但在手部几何形状上有所不同。改进后的接口减少了报告的物理需求,提高了所选设备的评分,使得在基线条件下机械阻挡的精确抓取中实现了触觉访问,并在记录的接触中产生了与任务相关的变化。盖子扭动主要表现为接触位置的变化,而打开蛋 carton 则主要表现为接触发生的变化。随后,我们使用二元聚合输入或空间加力输入训练匹配的策略。在盖子扭动和打开蛋 carton 的任务中,基于改进接口演示训练的策略比基于基线演示训练的策略取得了更高的成功率,并且存在显著的聚合接口效应。在这两个任务以及另外两个任务(USB 插入和焊接工具的拾取与放置)中,空间加力输入同样优于二元聚合。这些结果表明,可穿戴收集硬件是机器人学习数据生成过程的一部分。因此,这类接口的评估不仅应通过操作员的体验进行,还应通过它们所记录的触觉互动和它们所支持的策略表现进行评估。

Toward Evidence-Driven Human-Agent-Robot Teaming for Earth-Independent Anomaly Triage

面向证据驱动的人机机器人团队协作以应对地球独立的异常分类
Lopez-Francos, Ignacio G, Gallagher, Alexis, Shalal, Samira
Abstract
Deep-space crews cannot rely on real-time ground support for urgent off-nominal events. Initial alerts may underdetermine cause, while discriminating evidence may reside in crew observations or at locations that are unsafe, costly, or unavailable for crew inspection. We present an evidence-driven architecture for human-agent-robot teaming in Earth-independent anomaly triage. Agentic AI is treated as a stateful coordinator over bounded, inspectable services rather than as a fully autonomous vehicle controller. A triage state manager maintains hypotheses, evidence provenance, uncertainty, operational context, and tool status; a crew-facing embodied agent elicits observations and explains assessment changes; and a mobile robot acquires targeted, localized evidence. Typed interfaces separate dialogue and orchestration from monitoring, robot command, context retrieval, and safety-critical control. Two scenarios illustrate the architecture: a crewed deep-space mission based on an actual ISS ammonia false alarm, where suspected contamination restricts crew access, and a power-interface anomaly at a crewed lunar base, where robotic inspection distinguishes a local connector fault from other causes ambiguous in remote telemetry. Our main contribution is an authority-bounded closed evidence-loop architecture, exercised in a hardware-in-the-loop integration prototype using Reachy Mini and an Innate MARS mobile robot.

HULK: Learning Whole-Body Forceful Loco-Manipulation for Humanoids

HULK:为类人机器人学习全身强力运动操控
Dang, An, Alvarez, Arturo Flores, Chen, Yu-Ming, Gartoll, Conor Mc, Sun, Helen, Ames, Aaron, Fazeli, Nima, Nambi, Manikantan
Abstract
Humanoid loco-manipulation of large, heavy objects demands forceful interaction across the entire body. However, such payloads shift a humanoid's center of mass and impose sustained loads across the upper body, challenging balance and command tracking. We present HULK, a whole-body control framework for forceful loco-manipulation. Using model predictive control (MPC) to guide reinforcement learning with predictions of the loaded dynamics, we train two teachers: one tracks arm motions under wrist forces, and the other locomotes while holding large objects against the body. A capture-point control barrier function augments the wrist-force teacher during training to improve balance under load. We distill both teachers into a single policy. Evaluation spans simulation and the Unitree G1. In simulation, the teacher with the barrier function achieves the lowest forward and lateral velocity tracking errors at 10 kg per arm among evaluated controllers and reduces aggregate divergent component of motion (DCM) excursion magnitude by 35.7% relative to MPC-guided reinforcement learning alone. Our wrist-force teacher withstands torso push disturbances of up to 130 N.

PhysEvo: Astra Can Act, Let It

PhysEvo:让Astra行动
Tian, Wenqing, Zhang, Zeyu, Liu, Zhaocheng, Liu, Fengwei, Liu, Qiang, Wang, Liang
Abstract
Astra can act, yet reliable manipulation depends on the system through which it observes and controls the world. We introduce PhysEvo, a framework for physical recursive self-improvement (RSI) around a single frozen model. A task agent executes robot tasks; a meta-agent uses the resulting trajectories to diagnose failures, revise tools and skills, and test corrections. The meta-agent can also improve its own diagnostic tools, so retained revisions support both later action and later self-improvement. This process develops joint-level control, evidence-seeking observation, and reusable manipulation skills without model-weight updates or a separately trained action policy. Across 42 RoboDojo tasks, held-out-layout evaluation of retained task-specific deployment versions yields a five-dimension average score of 68.14/100 and 62.00% success, compared with 47.17% for RoboDawn's one-shot Astra agent, the strongest published reference in our comparison. On eight manipulation tasks challenging direct Astra, PhysEvo achieves 55.00% success, compared with 1.25% for the direct-Astra reference. Deploying the simulation-evolved harness on AgileX PiPER and continuing skill revision yields 90.60/100 average score and 84.00% success across 25 trials on five real-world tasks. PhysEvo turns the consequences of action into persistent, testable changes to how a frozen model acts and improves.

MimicX: Policy-in-the-Loop Supervision Refinement for Video-Driven Humanoid Motion Tracking

MimicX:基于策略的监督循环精炼用于视频驱动的人形运动跟踪
Liu, Shuaijun, Zhang, Chenglong, Liu, Xuhao, You, Feiyang, Liao, Yifan, Hao, Shuyang, Zhang, Chaozhe, Wu, Chengyu, Sun, Zhen, Su, Ningxin
Abstract
Human videos provide rich motion targets for humanoid learning, yet visually plausible references can still produce persistent failures under physics-based execution. These failures reveal where training supervision should change. We present MimicX, a policy-in-the-loop framework that uses execution feedback to refine video-driven humanoid motion tracking. Starting from reconstructed and retargeted motion, MimicX localizes difficult transitions and affected body regions, then jointly adapts tracking objectives and the reset curriculum for policy continuation. Repeated rollout verification selects execution-priority improvements subject to tracking guards. Across four core video tasks, MimicX consistently improves tracking accuracy and Robust Execution Horizon relative to the Fixed Reference baseline. Task-averaged results show a 25.7% reduction in body-tracking error and a 255.6% increase in execution horizon. Additional video, motion-reference, and collision-scene studies evaluate the method beyond the core tasks, while MimicX-HLoop accelerates feedback through heterogeneous execution. Overall, MimicX turns policy failure into actionable supervision for deciding what to refine and which refinement to retain.

Workhorse: Learning Robust Whole-Body Humanoid Loco-Manipulation from Human Data

工作马:从人类数据中学习稳健的全身类人机器人运动操控
Hu, Songbo, Liao, Qiayuan, Chi, Yufeng, Zakka, Kevin, Shao, Yakun Sophia, Abbeel, Pieter, Sreenath, Koushil
Abstract
Humanoid robots still struggle to plan contact-rich whole-body manipulation from egocentric RGB and proprioception. Workhorse learns such manipulation from robot-free human demonstrations. A visual planner predicts five-link targets: the poses of the torso, both wrists, and both feet. A reinforcement-learning whole-body tracker follows them on the robot. Both policies train separately on the same recorded human poses, without retargeting. We augment the training data of each policy to imitate the errors that the other makes at deployment. On a real Unitree G1, Workhorse sorts boxes with its hands and a kick, catches a thrown box, and topples and climbs a suitcase. During box sorting, we show recoveries after a person pushes the robot or takes the box away. In a simulated copy of the demonstration room, the system completes box sorting in 77% of episodes, and in 64% under 40 N.s pushes. With both policies retrained from the same demonstrations, a simulated second humanoid completes box sorting in 83% of episodes without pushes.

Abstract
Compared with analytical physics, learned dynamics models promise robot simulation that is faster, inherently differentiable, and easily adaptable to real data. Neural Robot Dynamics (NeRD) pursues this by keeping collision detection analytical and replacing a simulator's numerical dynamics for the robot with a learned model. Three limitations remain. NeRD offers little speedup over the simulator it learned from, accepts contact only at predefined points, and has no two-way coupling with objects it manipulates. FlashNeRD removes all three with a parallel streaming architecture that makes each prediction faster and more accurate, an encoder that accepts contacts wherever they occur, and two-way coupling with objects simulated by analytical solvers. Experiments across five robots show faster and more accurate dynamics, faster policy learning, and faster inference-time planning. Across three robots, FlashNeRD's dynamics model is up to $55\times$ faster than an optimized NeRD and more accurate over long rollouts. This speedup extends to policy learning, where PPO trains an ANYmal locomotion policy in 34 seconds, $3.8\times$ faster than the analytical simulator and $2.7\times$ faster than an optimized NeRD. With DIAL-MPC, a sampling-based MPC method, the robot climbs all six test platforms where fixed-contact NeRD manages one, at approximately half the analytical simulator's planning time. Cube-reorientation policies trained with FlashNeRD complete within 2% of the simulator-trained policy's target count.

与解析物理相比,学习的动力学模型承诺提供更快、内在可微且易于适应真实数据的机器人仿真。神经机器人动力学(NeRD)通过保持碰撞检测的解析性,并用学习模型替代机器人的数值动力学来实现这一目标。然而,仍然存在三个局限性。NeRD相较于其学习的仿真器提供的加速效果有限,仅在预定义点接受接触,并且与其操控的物体之间没有双向耦合。FlashNeRD通过并行流架构消除了这三点限制,使每次预测更快、更准确,采用的编码器可以在任何接触发生的地方接受接触,并实现与由解析求解器模拟的物体之间的双向耦合。针对五个机器人的实验表明,FlashNeRD实现了更快且更准确的动力学、更快的策略学习和更快的推理时间规划。在三个机器人中,FlashNeRD的动力学模型比优化后的NeRD快多达$55 imes$,并且在长时间滚动中更为准确。这种加速也延伸到策略学习,其中PPO在34秒内训练出ANYmal的运动策略,比解析仿真器快$3.8 imes$,比优化后的NeRD快$2.7 imes$。使用DIAL-MPC这一基于采样的MPC方法,机器人能够攀爬所有六个平台,而固定接触的NeRD仅能管理一个,且规划时间约为解析仿真器的一半。使用FlashNeRD训练的立方体重新定向策略在目标计数上完成的结果与仿真器训练的策略相差不超过2%。

World Models Dream of Success: Diagnosing and Repairing Failure Insensitivity in Robot World Models

世界模型梦想成功:诊断和修复机器人世界模型中的失败敏感性缺失
Xu, Jiuyi, Hu, Xiao, Chen, Meida, Gao, Peng, Ye, Yang, Shi, Yangming
Abstract
Robot world models support policy evaluation, planning, and synthetic data generation, but these applications require predictions that distinguish successful actions from failures. Across four released checkpoints from two architecture families, we observe weak sensitivity to action changes and success-like predictions on verified failures. Although recent work incorporates failures into model training, which data can repair released checkpoints without changing their architecture or training objective still remains underexplored. To this end, we introduce CureWM, which constructs alternative actions from successful demonstrations across a severity grid, verifies their outcomes through execution in simulation or on hardware, and fine-tunes released models on the resulting failures and surviving successes alongside nominal demonstrations. This construction provides controlled action contrasts from shared starting contexts. On 484 held-out LIBERO failure counterfactuals, optimism falls from 80\% after fine-tuning on the official data to 30--43\% across four independently fine-tuned CureWM models (38\% mean). In two separate evaluations on a physical robot arm, failure predictions scored as success-like by a latent-distance diagnostic decrease from 90\% after fine-tuning on successful demonstrations alone to 33\% with CureWM. With failure counts per task, successful replay data, and training budget matched, counterfactual failures yield a success--failure value gap of 0.124, compared with 0.014 for freshly collected on-policy failures. These findings support execution-verified counterfactual replay for post-hoc repair and show why reduced optimism must be evaluated alongside success--failure discrimination.

机器人世界模型支持策略评估、规划和合成数据生成,但这些应用需要能够区分成功行动与失败的预测。在两个架构系列的四个发布检查点中,我们观察到对行动变化的敏感性较弱,并且在经过验证的失败上产生类似成功的预测。尽管近期的研究将失败纳入模型训练,但哪些数据能够在不改变其架构或训练目标的情况下修复已发布的检查点仍然未得到充分探索。为此,我们提出了CureWM,它通过在严重性网格上从成功示范中构建替代行动,通过在模拟或硬件上执行验证其结果,并在生成的失败和存活成功以及名义示范上对已发布模型进行微调。这种构建提供了来自共享起始上下文的受控行动对比。在484个保留的LIBERO失败反事实中,经过在官方数据上微调后,乐观度从80%下降到四个独立微调的CureWM模型的30%至43%(平均38%)。在对一个物理机器人手臂的两个独立评估中,潜在距离诊断认为的失败预测在仅针对成功示范微调后从90%下降到使用CureWM后的33%。在每个任务的失败计数、成功重放数据和训练预算匹配的情况下,反事实失败产生的成功-失败价值差距为0.124,而新收集的政策内失败为0.014。这些发现支持经过执行验证的反事实重放用于事后修复,并表明为什么减少的乐观度必须与成功-失败区分一起进行评估。代码可在 https://github.com/jiuyixu25/CureWM 获取。

A Unified Kinematic Representation Enables Reusable Biological Joint Moment Estimation

统一的运动学表示法实现可重用的生物关节力矩估计
Hwang, Jinwoo, Park, Ilseung, Song, Changseob, Phan, Vu, Halilaj, Eni, Kang, Inseung
Abstract
Objective: Data-driven models that estimate physiological states, particularly biological joint moments, are widely used in exoskeleton control. However, these estimators are often coupled to device-specific sensor configurations, limiting controller transfer and the use of open-source biomechanics datasets. Methods: We proposed joint kinematics as an intermediate representation that decouples hardware-specific sensing from downstream biological joint moment estimation. A joint-moment estimator using joint angles and angular velocities was trained exclusively on open-source biomechanics data and evaluated using kinematics from a hip exoskeleton, knee exoskeleton, and inertial measurement unit (IMU) sensor suite during level-ground, ramp-ascent, and ramp-descent walking. Results: The estimator achieved an root mean square error (RMSE) of 0.17 Nm/kg and coefficient of determination (R2) of 0.79 using hip exoskeleton kinematics, 0.19 Nm/kg and 0.62 using knee exoskeleton kinematics, and 0.15 Nm/kg and 0.85 using kinematics derived from IMUs across bilateral hip, knee, and ankle joints. Conclusion: Joint kinematics enabled an estimator trained only on open-source data to operate across distinct wearable platforms. Significance: This framework may reduce target-device data collection and support transferable biological joint moment estimation for exoskeleton control and wearable biomechanics.

geodex: A Library for Motion Planning on Riemannian Manifolds

geodex:一个用于黎曼流形上运动规划的库
Kyaw, Phone Thiha, Wei, Ben, Samavi, Sepehr, Garcia, Miguel Angel Rogel, Kelly, Jonathan
Abstract
Planning motions that respect the intrinsic geometry of a robot's configuration space, including its curvature and a configuration-dependent notion of cost, yields shorter, lower-energy, and more natural trajectories than planning under the ambient flat metric. Existing libraries for optimization on manifolds provide rich geometric primitives but do not plan around obstacles. While general-purpose motion planning libraries support many state spaces and custom distance functions, they do not yet treat a configuration-dependent Riemannian metric as the geometry that drives distance, interpolation, and geodesics. We present geodex, an open-source C++20 library with Python bindings. The library exposes the manifold, its Riemannian metric, the retraction, and the sampler as independent, interchangeable components through a single sampling-based motion planning interface. The same planner runs unchanged on canonical spaces $\mathbb{R}^n$, $\mathbb{T}^n$, $\mathbb{S}^n$, matrix Lie groups such as $SO(2)$, $SE(2)$, $SO(3)$, and $SE(3)$, products of these spaces, and articulated-robot configuration spaces, each equipped with a user-defined Riemannian metric. We make geodex publicly available with documentation, tests, and a reproducible benchmark suite.

Beyond Reconstruction: What Matters in Action Tokenization for Robot Policies?

超越重建:在机器人策略中,动作标记化的关键是什么?
Chen, Haoran, Ji, Jingtian, Wheeler, Samuel, Stocking, Kaylene Caswell, Walter, Matthew
Abstract
Autoregressive action-token policies such as vision-language-action models require action tokenizers to translate discrete token sequences into precise control actions in continuous space. Many action tokenizers learn the mapping between tokens and actions via a reconstruction objective. However, as we show through extensive analysis, sufficiently accurate action reconstruction is only one part of what makes a downstream robot policy successful. It is also critical that the policy is able to predict the right tokens for new observations, and that unseen policy token predictions still decode into reasonable actions. These properties are downstream of tokenizer training and are not directly incentivized by a reconstruction objective alone. In this work, we introduce Predictable and Robust Action Tokenization (ProAct), a tokenizer training method that strategically augments reconstruction with the goal of improving downstream predictability and robustness. ProAct is policy-agnostic and uses only action datasets for training. Across the Robomimic, LIBERO, and RoboTwin benchmarks and a diverse set of tokenizer architectures, ProAct improves rollout success by an average of 11.3 percentage points. These improvements also translate to vision-language-action policies and real-world robotic manipulation, yielding average gains of 21.8 and 36.7 percentage points, respectively. These results suggest that effective action tokenization should be designed as a policy interface that balances fidelity, predictability, and robustness, rather than as a reconstruction problem alone.

自回归动作标记策略,如视觉-语言-动作模型,需要动作标记器将离散标记序列转换为连续空间中的精确控制动作。许多动作标记器通过重建目标学习标记与动作之间的映射。然而,通过广泛的分析,我们表明,足够准确的动作重建只是使下游机器人策略成功的一部分。策略能够为新观察预测正确的标记,以及未见策略标记预测仍然解码为合理动作,这些都是至关重要的。这些特性是在标记器训练的下游,并不是仅通过重建目标直接激励的。在本研究中,我们引入了可预测和鲁棒的动作标记化(ProAct),这是一种标记器训练方法,战略性地增强重建,以改善下游的可预测性和鲁棒性。ProAct与策略无关,仅使用动作数据集进行训练。在Robomimic、LIBERO和RoboTwin基准测试以及多样化的标记器架构中,ProAct平均提高了11.3个百分点的回滚成功率。这些改进也转化为视觉-语言-动作策略和现实世界的机器人操作,分别带来了平均21.8和36.7个百分点的提升。这些结果表明,有效的动作标记化应被设计为一种策略接口,平衡保真度、可预测性和鲁棒性,而不仅仅是作为一个重建问题。

CAP: Codebook-Aligned Prediction for Tokenized Robot Policies

CAP:与代码本对齐的标记化机器人策略预测
Chen, Haoran, Ji, Jingtian, Wheeler, Samuel, Stocking, Kaylene Caswell, Walter, Matthew
Abstract
Action tokenization converts continuous robot actions into discrete symbols that can be modeled autoregressively. However, existing tokenizer-based policies typically ignore the tokenizer's learned latent code structure: after tokenization, the policy treats tokens as unrelated class indices and learns a new classifier from scratch. We show that this discarded structure is valuable. We introduce Codebook-Aligned Prediction (CAP), a method that directly reuses the tokenizer's code vectors as policy class prototypes while leaving the tokenizer and policy backbone otherwise unchanged. Across four quantizer families, three simulation benchmarks, and two real-robot tasks, CAP consistently improves task success over standard token classification heads while holding the tokenizer (and therefore its reconstruction quality) fixed. Our analysis further shows that these gains are not explained by higher token accuracy or changes in the policy head alone. Instead, reusing the tokenizer codebook provides the policy with valuable information about the tokenizer's learned latent structure across tokens, making token prediction errors more benign in action space and improving the representations learned by the policy backbone. These results suggest that action tokenizers learn useful action-aware latent structure beyond discrete targets that should be preserved when training downstream policies.

动作标记化将连续的机器人动作转换为可以自回归建模的离散符号。然而,现有的基于标记器的策略通常忽略了标记器学习到的潜在代码结构:在标记化之后,策略将标记视为无关的类别索引,并从头开始学习一个新的分类器。我们表明,这一被丢弃的结构是有价值的。我们提出了与代码本对齐的预测(Codebook-Aligned Prediction, CAP),这是一种直接重用标记器的代码向量作为策略类别原型的方法,同时保持标记器和策略主干不变。在四个量化器家族、三个仿真基准和两个真实机器人任务中,CAP在保持标记器(因此保持其重建质量)不变的情况下,始终提高了任务成功率,超越了标准的标记分类头。我们的分析进一步表明,这些增益并不能仅通过更高的标记准确性或策略头的变化来解释。相反,重用标记器代码本为策略提供了关于标记器学习到的潜在结构的有价值信息,使得在动作空间中的标记预测错误更加温和,并改善了策略主干学习到的表示。这些结果表明,动作标记器学习到了超越离散目标的有用的动作感知潜在结构,在训练下游策略时应予以保留。

Embedded Evaluation of Task Admission Coalescing in Decentralized Multi-Robot Systems

去中心化多机器人系统中任务接纳合并的嵌入式评估
Lott, James, Honary, Vahraz
Abstract
Multi-robot task allocators in dynamic missions commonly admit newly released tasks immediately, potentially invoking allocation for each new arrival. We evaluate task-admission coalescing as a mechanism for controlling allocator processor work while accounting for target-service latency, using CBAA, ACBBA, PI, and HIPC as a representative MRTA suite. The study comprises a 3,000-mission AGX Orin campaign with measured computation delay, 3,000 paired zero-compute missions, and a 96-mission Pololu 3pi+ RP2040 allocator hardware-in-the-loop campaign. Immediate (Eager) admission is compared with thresholds of two, four, and eight tasks and a four-task policy with a 10-s waiting bound across three arrival rates. Across the AGX experiments, coalescing reduces both allocator calls and processor work in 31 of 48 evaluated conditions, although the magnitude of the saving varies by allocator. The principal cost appears under sparse arrivals, where four-task batching increases online-target mean latency by 20.08-23.57 s, predominantly through admission waiting. Bounded admission reduces mean work in ten of twelve allocator-load conditions, including a 19.35% reduction with a 1.40-s mean latency increase for high-arrival HIPC. RP2040 experiments show that this tradeoff can become more favorable as processor constraints tighten. Across four matched medium-arrival HIPC scenarios, Count b=4 reduces mean RP2040 work by 59.85% and service latency by 39.47%, while the corresponding AGX cases increase latency by 27.69%. These results show that the usefulness of task-admission coalescing depends on arrival intensity, allocator-specific behavior, and the relative cost of computation on the execution platform.

Belief-Space Planning with Planner-Conditioned Estimator Error under Intermittent Observations

在间歇性观测下的规划者条件估计误差的信念空间规划
Donley, Peter M., Moore, Joseph L.
Abstract
Belief-space planners with separately designed or off-the-shelf estimators may have access to state-relevant information the estimator does not observe. Consequently, even an estimator that minimizes mean-squared error under its own information can have a nonzero error mean when conditioned on planner information. When future corrections are intermittent and stochastic, differences between accepted and rejected error means introduce additional uncertainty terms to correction events that zero-mean assumptions ignore. In this paper, we propose a belief-space planning approach that predicts, propagates, and penalizes planner-conditioned estimator error along evaluated trajectories. A planner-conditioned estimator-error model combines affine error dynamics with a moment recursion that preserves stochastically-induced correction uncertainty. We describe a method by which to predict estimator error dynamics within specified operating regimes and incorporate predicted error moments into a task-weighted quadratic risk objective. We evaluate the approach in simulation for a tilt-rotor VTOL landing on a ship deck using receding-horizon planning. We find that conditioning on planner information reduced error-prediction loss for a command-blind EKF by 13.4% relative to a planner-ignorant model, with strongly regime and horizon-dependent forecasting abilities. In a small set of 16 paired closed-loop trials, the planner lowered the median terminal task gauge from 1.60 to 0.99, and predicted estimator error beyond 2s within a factor of 1.3, versus a 5.7-fold underprediction by covariance-only planning.

Fast Planning for Multi-object Multi-target Throwing

多物体多目标投掷的快速规划
Zhu, Zhengming, Liu, Yang, Gao, Xiao, Billard, Aude
Abstract
Robot throwing has emerged as a promising technique for improving efficiency in logistics and warehouse automation, by enlarging the workspace and speeding up the process. To significantly increase the throwing system's throughput, we develop strategies for throwing multiple objects in one swipe. Such multi-object multi-target throwing (MOMT) leverages the large degrees of freedom of anthropomorphic hands. The key is to quickly generate fast and feasible throwing motions, which involves a complex trade-off between short trajectory duration and short planning time. We solve this problem in two stages. Offline, we build a model of the feasible set by combining object's inverted flying dynamics and the robot's kinematics and dynamics. Online, we generate feasible throws through fast solution matching and filtering of object's valid detach state and robot's feasible state that can compose sequences of throws in less than 5 ms. We validate the framework on a 7-DoF manipulator equipped with a multi-fingered hand. In simulation, coordinated two-object throwing reduces execution time by up to 46% compared to independent single-object planning, and this improvement is maintained when scaling to three objects. Real-world experiments with two objects confirm a 29% reduction; the remaining gap to the theoretical 50% is attributed to inter-throw transition overhead. When target positions are randomly changed mid-execution, the system re-plans and successfully reaches the new targets within 100 ms latency without stopping the robot. These results establish the first unified planning framework for MOMT throwing -- demonstrating scalability to multiple objects in simulation and real-world feasibility on two-object tasks -- advancing the frontier of high-throughput robotic manipulation.

机器人投掷作为一种有前景的技术,已被广泛应用于提高物流和仓库自动化的效率,通过扩大工作空间和加快过程。为了显著提高投掷系统的吞吐量,我们开发了在一次动作中投掷多个物体的策略。这种多物体多目标投掷(MOMT)利用了类人手的高度自由度。关键在于快速生成快速且可行的投掷动作,这涉及到短轨迹持续时间与短规划时间之间的复杂权衡。我们将此问题分为两个阶段进行解决。离线阶段,我们通过结合物体的倒飞动态和机器人的运动学与动力学,构建可行集模型。在线阶段,我们通过快速解决匹配和过滤物体的有效分离状态及机器人可行状态,生成可行的投掷动作,能够在不到5毫秒的时间内组合投掷序列。我们在一台配备多指手的7自由度机械臂上验证了该框架。在仿真中,协调的双物体投掷相比独立的单物体规划,执行时间减少了多达46%,而这一改进在扩展到三物体时仍然保持。与两个物体的实际实验确认了29%的减少;剩余的差距归因于投掷间的过渡开销。当目标位置在执行过程中随机改变时,系统重新规划并成功在100毫秒的延迟内到达新目标,而无需停止机器人。这些结果建立了第一个统一的MOMT投掷规划框架——在仿真中展示了对多个物体的可扩展性,并在双物体任务中验证了现实世界的可行性——推动了高吞吐量机器人操作的前沿。关于该方法及硬件实验的总结视频可在 https://liuyangdh.github.io/momt-video 查阅。

Co-Evolving Robot Orchestrators and Policies through Deployment

通过部署共同进化的机器人协调者和策略
Zhang, Xilun, Wang, Maggie, Bauer, Erik, Yu, Hong-Xing, Huang, Huang, Wu, Jiajun, Pavone, Marco
Abstract
Vision-language-action (VLA) policies trained on large datasets are capable within their training domains, yet they still fail to generalize to the variety of situations a robot meets in real-world deployment. Agentic robot systems complement the policy with a vision-language model (VLM) orchestrator that learns when to call the policy, how to instruct it, and when to use scripted skills instead. However, because the harness is built around a frozen policy that has limited language steerability, the orchestrator can avoid the policy's failures but never overcome them. The policy becomes the bottleneck of the whole system. Fine-tuning the policy can remove this bottleneck, but updating it alone decouples it from an orchestrator tuned to its old behavior. We propose Robo-COP, in which the orchestrator and policy co-evolve during deployment. Robo-COP curates skill demonstrations from its own executions, fine-tunes the policy when this data can address recurring failures, and adopts each new policy only after it improves the skills it was trained for. Across ten simulated RoboLab tasks, Robo-COP raises mean held-out success from 64.8% to 73.8% over the same harness with a frozen policy, while fine-tuning on a fixed schedule without verification reaches only 65.8%. On three real-world tasks, Robo-COP raises held-out success from 38.3% to 50.0%. Robo-COP turns deployment into a self-improving flywheel in which robots learn by doing, with each improvement in execution producing better data for the next round of learning.

RoboRender: Robot-Oriented Video Generation for Visual Sim-to-Real Transfer

RoboRender:面向机器人视频生成的视觉仿真到现实转移
Huang, Huang, Ai, Wensi, Chen, Ziyu, Wang, Youhui, Du, Zijian, Liu, Yang, Yang, Jiaolong, Fei-Fei, Li, Wu, Jiajun
Abstract
Simulation enables large-scale, low-cost robot data generation, but policies trained in simulation often fail to transfer to the real world due to the sim-to-real visual discrepancies. Existing approaches often rely on intermediate representations, which can discard rich semantic information or require additional perception modules at deployment. We address this visual sim-to-real gap with RoboRender, a framework that converts simulated trajectories into photorealistic RGB videos for policy learning. RoboRender trains a robot-oriented video generation model conditioned on simulated depth videos, language instructions, and robot RGB mask videos, preserving simulator geometry, robot motion, and action labels while synthesizing realistic textures, backgrounds, and distractors. The generated RGB videos are paired with simulator-provided states and actions to train policies for zero-shot real-world deployment. On robot video test sets, our video model outperforms depth-conditioned video generation baselines in generation quality. In real-world experiments across pick-and-place, articulated-object manipulation, and mobile manipulation tasks, policies trained on RoboRender-generated data achieve a 71% average success rate, outperforming raw simulation renderings and conventional visual domain randomization by approximately 7.1x and 3.6x, respectively. We further show that policy performance improves with more generated videos per simulation trajectory, increasing opening-task success by 65 percentage points.

仿真技术使得大规模、低成本的机器人数据生成成为可能,但在仿真中训练的策略往往无法有效转移到现实世界,原因在于仿真与现实之间的视觉差异。现有的方法通常依赖于中间表示,这可能会丢失丰富的语义信息,或在部署时需要额外的感知模块。我们通过RoboRender框架解决了这一视觉仿真到现实的差距,该框架将仿真轨迹转换为用于策略学习的照片级真实感RGB视频。RoboRender训练了一种面向机器人的视频生成模型,该模型以仿真深度视频、语言指令和机器人RGB掩码视频为条件,保留了仿真器几何形状、机器人运动和动作标签,同时合成了真实的纹理、背景和干扰物。生成的RGB视频与仿真器提供的状态和动作配对,以训练零-shot现实世界部署的策略。在机器人视频测试集中,我们的视频模型在生成质量上优于基于深度条件的视频生成基线。在跨越抓取与放置、关节物体操控和移动操控任务的现实世界实验中,基于RoboRender生成数据训练的策略实现了71%的平均成功率,分别比原始仿真渲染和传统视觉领域随机化提高了约7.1倍和3.6倍。我们进一步显示,随着每条仿真轨迹生成更多视频,策略性能得到了提升,开启任务的成功率提高了65个百分点。这些结果表明,生成视频渲染减轻了零-shot策略转移中的视觉仿真到现实的差距。项目网站:https://robo-render.github.io/

Evaluating the Transfer of Co-Evolved Communication from 2D to 3D Simulation

评估共进化通信从二维到三维仿真的转移
Montes-Gonzalez, Fernando
Abstract
This work examines the transfer of a co-evolved communication mechanism between two robotic agents from a discrete two-dimensional (2D) simulator to a three-dimensional simulator with real physics (3D). The study focuses on whether a communication mechanism co-evolved in a 2D environment retains its functional role after transfer to a 3D physics-based simulator. To support this analysis, the effects of the episode time budget, the social cue, and the asymmetry between the two co-evolved roles were examined. The results indicate that the success rate increased approximately linearly with the evaluated time budgets, with no evidence of a plateau between 2,000 and 6,000 physics steps, suggesting that evaluations based on shorter episodes may underestimate the performance of the trained controllers. In both simulators, the social cue functioned primarily as a jam- assistance mechanism rather than as a navigation guide, although with a more pronounced effect in 2D. Analysis of eight independent evolutionary runs revealed a consistent direction of asymmetry, although its magnitude varied across runs. Controlling the processing order between agents allowed us to rule out an artifact of the physics engine. Finally, the results are discussed in terms of the factors that may contribute to the remaining performance gap observed after transfer.

本研究考察了两个机器人代理之间的共进化通信机制从离散的二维(2D)仿真器转移到具有真实物理的三维(3D)仿真器的过程。研究重点在于,在二维环境中共进化的通信机制在转移到基于物理的三维仿真器后是否仍能保持其功能角色。为支持这一分析,考察了情节时间预算、社会线索以及两个共进化角色之间的不对称性对结果的影响。结果表明,成功率与评估的时间预算大致呈线性增加趋势,在2000到6000个物理步骤之间没有出现平台效应,这表明基于较短情节的评估可能低估了训练控制器的性能。在两个仿真器中,社会线索主要作为干扰辅助机制而非导航指南,尽管在二维中效果更为显著。对八次独立进化实验的分析揭示了一致的不对称性方向,尽管其幅度在不同实验中有所变化。控制代理之间的处理顺序使我们能够排除物理引擎的伪影。最后,讨论了可能导致转移后观察到的性能差距的因素。

LACE-CRAFT: Robot Co-Design with Actor Inheritance and Blackboard Collaboration

LACE-CRAFT:具有行为者继承和黑板协作的机器人共同设计
Wen, Yuhan, Wang, Jiawei, Zhang, Qixuan, Qin, Yusen, Xu, Lan
Abstract
Robot co-design couples morphology search with policy learning, yet training every new design from scratch discards acquired control experience. We present LACE-CRAFT, which compares continued learning on the current robot with policy adaptation to new morphology-reward pairs. LACE resumes the incumbent's full learning state and initializes compatible challengers with its actor parameters and observation statistics. A fixed task metric selects among both branches and the frozen incumbent. CRAFT coordinates Feedback, Morphology, Reward, and Integration roles through shared experimental records and behavioral replays to generate and cross-review paired proposals. A generative extension converts generated meshes into editable articulated models with configured joints, actuator interfaces, and consistently updated simulation assets. Across five locomotion benchmarks, mean scores over three evaluation seeds are 6.4-91.9% higher than D2C. Both methods train 30 new morphology-reward pairs over five rounds; LACE additionally uses four continuation training units. Five-task ablations examine policy inheritance and replay-derived feedback. A fabricated prototype demonstrates indoor walking and illustrates the geometry-to-hardware workflow.

Co${}^{2}$Skill: Whole-Body Control via Skill Composition for Long-Horizon Human-Environment Interaction

Co${}^{2}$Skill:通过技能组合实现长时间人机环境交互的全身控制
Kim, Jeonghwan, Kim, Hyeonwoo, Joo, Hanbyul
Abstract
Achieving human-level dexterity in complex, unstructured environments requires the seamless integration of whole-body scene interaction and dexterous object manipulation skills. While existing physics-based controllers generate physically plausible behaviors in each domain, they largely address these two capabilities independently. In this paper, we present Co${}^{2}$Skill that integrates scene interaction and dexterous manipulation through a unified policy formulation. Built on a pretrained motion prior, the policy uses task and phase dependent observation masks to select information relevant to the current interaction goals. We introduce a goal-conditioned loco-manipulation curriculum that combines partial reference guidance for precision with exploration from varied initial states while allowing goal-directed execution beyond the demonstrated trajectories. We further introduce a cross-task curriculum that jointly trains individual skills and selected task sequences, preserving physical states across task boundaries and maintaining grasps during subsequent scene interactions. Together, these support sequential task execution and simultaneous scene interaction with object manipulation. We evaluate sitting, standing, climbing, stair traversal, and goal-directed manipulation, together with sequential execution and with random different conditions. Additionally, we demonstrate skill compositions in indoor environments, illustrating their integration within the same control formulation.

Adaptive Risk-Certified Event-Triggered Replanning for Dynamic Navigation

动态导航的自适应风险认证事件触发重规划
Suganda, Richie R., Hu, Bin
Abstract
Safe navigation in dynamic environments requires robots to plan under obstacle predictions whose errors are uncertain, non-stationary, and can induce rare but safety-critical failures. Existing control-barrier-function safety filters can reject immediately unsafe controls, but they provide little guidance on when the current finite-horizon planning mode itself is becoming unsafe as prediction uncertainty evolves. We propose Conformal Event-Triggered Risk-Certified Replanning (\emph{CERT-Replan}), a framework that uses calibrated barrier risk as an early-warning signal for replanning. CERT-Replan calibrates horizon-indexed obstacle-prediction residuals online and uses the resulting uncertainty radii to evaluate dynamic-obstacle safety margins. A one-step safety filter protects the next applied control, while a horizon-level risk monitor evaluates the upper-tail CVaR of predicted barrier-violation losses along the current MPC rollout. When this risk exceeds an allocated budget, CERT-Replan rejects the current planning mode and selects a lower-risk alternative, such as a different speed profile, corridor, or homotopy class, rather than repeatedly correcting the same nominal plan. In a non-stationary benchmark, CERT-Replan achieves an \(83.3\%\) collision reduction relative to the safety-filter-only baseline \textcolor{black}{and a \(77.8\%\) reduction relative to simple replanning triggers}, while reducing average safety-filter intervention by \(32.4\%\). \textcolor{black}{With Trajectron++, CERT-Replan achieves \(96\%\) collision-free operation. Hardware experiments and onboard runtime profiling demonstrate computational feasibility.}

在动态环境中安全导航要求机器人在障碍物预测下进行规划,而这些预测的误差是不确定的、非平稳的,并且可能导致罕见但对安全至关重要的失败。现有的控制障碍函数安全过滤器可以立即拒绝不安全的控制,但对于当前有限时间规划模式在预测不确定性演变时何时变得不安全提供的指导有限。我们提出了符合事件触发的风险认证重规划框架(Conformal Event-Triggered Risk-Certified Replanning,简称CERT-Replan),该框架利用校准的障碍风险作为重规划的早期预警信号。CERT-Replan在线校准以时间为索引的障碍物预测残差,并利用得到的不确定性半径来评估动态障碍物的安全边际。一步安全过滤器保护下一步应用的控制,而水平风险监测器评估当前模型预测控制(MPC)展开过程中预测的障碍物违反损失的上尾条件价值风险(CVaR)。当此风险超过分配的预算时,CERT-Replan拒绝当前的规划模式,并选择一个风险更低的替代方案,例如不同的速度配置、走廊或同伦类,而不是反复修正相同的名义计划。在一个非平稳基准测试中,CERT-Replan相较于仅使用安全过滤器的基线实现了83.3%的碰撞减少,相较于简单重规划触发器减少了77.8%,同时将平均安全过滤器干预减少了32.4%。使用Trajectron++,CERT-Replan实现了96%的无碰撞操作。硬件实验和机载运行时分析证明了计算的可行性。

Predicted Futures Are Not Enough: Learning Executable Goals for Robot Manipulation

预测的未来不足够:学习可执行的机器人操作目标
Chuang, Tzu-Yu, Chang, Ching-Hsiang, Lee, Yi-Hsiu, Chen, Yi-Ting, Sun, Min, Yang, YuanFu
Abstract
Generative world models provide rich predictions of how manipulation scenes may evolve toward task objectives, yet those futures do not directly expose the compact task variables required by control. When training supervises future prediction alone, terminal goal accuracy is not an explicit learning objective, even when geometric recovery is available. We present Entity-Level Goal Readout, a learned prediction-to-execution interface that makes the executable terminal goal an explicit output of a 3D trace world model. It combines object-centric pose prediction with translation grounded in observed depth to produce a compact goal in SE(3). A shared Pose-Native Executor consumes this fixed goal with online object-pose feedback for closed-loop control without rerunning the world model. Across five manipulation tasks, the pipeline achieves a mean success rate of 79.69%. Goal diagnostics directly measure terminal goal accuracy, while controlled translation perturbations characterize how execution degrades under goal error. Zero-shot deployment on a Franka arm achieves 73.33% success on nominal StackCube, 66.67% with distractors, and 75.00% on PickPlate with a target unseen during policy training. These results support treating the prediction-to-execution interface as an explicit learned component of world-model planning rather than incidental post-processing in the control pipeline itself.

MCFR: A Mask-Guided Coarse-to-Fine Regression Framework for Robust Multi-Variant Board-to-Board Connector Assembly

MCFR:一种面向鲁棒多变体板对板连接器装配的掩码引导粗到细回归框架
Shen, Guanghui, Wang, Song, Wu, Dan
Abstract
Automated insertion of board-to-board (BTB) connectors in 3C manufacturing requires both high visual accuracy and strong deployment robustness. This problem remains challenging because multi-variant connectors exhibit significant morphological and appearance variations, making stable cross-variant generalization difficult, while the mismatch between training and deployment under fixed-view inspection settings induces background spurious correlation and degrades real-world performance. To address these issues, this paper proposes MCFR, a Mask-Guided Coarse-to-Fine Regression framework for multi-variant BTB connector assembly. By introducing an object-aware mask prior and explicit photometric refinement, the proposed method suppresses background interference and improves alignment accuracy and robustness in practical deployment. Experiments on a self-constructed multi-variant dataset, a BTB batch insertion testbed, and a real smartphone assembly task show that MCFR consistently outperforms representative baselines and achieves an average real-world insertion success rate of 99.25%. These results demonstrate the effectiveness and practical potential of MCFR for automated assembly of multi-variant BTB connectors.

Learning Unknown Constraints without Unsafe Data via Optimality and Counterfactual Regularization

通过最优性和反事实正则化学习未知约束,无需不安全数据
Zhang, Zhouyu, Chiu, Chih-Yuan, Chou, Glen
Abstract
Learning from demonstrations (LfD) provides a framework for inferring unknown constraints from locally optimal, constraint-satisfying expert behavior. Existing approaches largely fall into two paradigms, constrained inverse optimal control (CIOC) and inverse constrained reinforcement learning (ICRL). CIOC exploits optimality conditions such as the Karush--Kuhn--Tucker (KKT) conditions but typically assumes known dynamics and structured constraint representations. Meanwhile, ICRL accommodates complex unknown constraints and unknown transition dynamics but often requires extensive online exploration, during which unsafe constraint violations may occur. In this work, we introduce Counterfactual KKT (CF-KKT), a constraint learning framework that leverages learned dynamics and locally optimal demonstrations to recover unknown constraints without requiring known dynamics or additional risky exploration, thereby combining the data efficiency and safety advantages of CIOC with the flexibility of ICRL. First, we use a locally learned differentiable dynamics model to impose KKT-inspired optimality conditions directly on the demonstrations. Second, we use the learned dynamics to generate reward-improving counterfactual behaviors near the demonstrations, revealing behaviors that would be preferable in the absence of the unknown constraint and thus providing synthetic infeasible data. When the constraint parameterization is known, the same learned-dynamics framework enables direct CIOC-based parameter recovery, and we characterize its sensitivity to dynamics misspecification. Across high-dimensional robotic control tasks, our approach learns neural constraint representations with improved safety and data efficiency relative to state-of-the-art offline ICRL baselines.

从示范中学习(LfD)提供了一种从局部最优、满足约束的专家行为中推断未知约束的框架。现有方法主要分为两种范式:约束逆最优控制(CIOC)和逆约束强化学习(ICRL)。CIOC利用最优性条件,如Karush-Kuhn-Tucker(KKT)条件,但通常假设已知动态和结构化约束表示。与此同时,ICRL能够处理复杂的未知约束和未知转移动态,但往往需要广泛的在线探索,在此过程中可能会发生不安全的约束违反。在本研究中,我们引入了反事实KKT(CF-KKT),这是一种约束学习框架,利用学习到的动态和局部最优示范来恢复未知约束,而无需已知动态或额外的高风险探索,从而将CIOC的数据效率和安全优势与ICRL的灵活性相结合。首先,我们使用局部学习的可微动态模型直接对示范施加受KKT启发的最优性条件。其次,我们利用学习到的动态生成奖励提升的反事实行为,这些行为接近示范,揭示了在没有未知约束的情况下更可取的行为,从而提供合成的不可行数据。当约束参数化已知时,相同的学习动态框架使得基于CIOC的参数恢复成为可能,并且我们描述了其对动态错误指定的敏感性。在高维机器人控制任务中,我们的方法学习到了相较于最先进的离线ICRL基线具有更高安全性和数据效率的神经约束表示。

COOL: Curiosity-Driven Object Ownership Learning for Personalized Robotic Assistance

COOL:基于好奇心驱动的个性化机器人助手对象所有权学习
Huber, Samira, Hammele, Ruben, Pirk, Sören
Abstract
Robots are increasingly expected to provide personalized services in everyday environments. To do so, they must ground natural-language commands such as "Where is my backpack?" or "Find my bottle" and execute them by reasoning about object instances, people, locations, and ownership. This is challenging because ownership is rarely labeled explicitly and must be inferred from long-term, behavioral evidence of human-object interactions. To address this, we present COOL, a novel robotic framework for autonomously learning object ownership from everyday observations and maintaining a long-term spatial memory of its environment. To keep its memory current, COOL uses an agent-based curiosity-driven data collection strategy that guides the robot toward the most promising locations to gain information and refresh stale observations. Offline experiments, ablation studies, and real-world evaluations show that COOL can infer ownership relations from real-world interactions and use this knowledge for ownership-conditioned navigation and task execution.

Immiscible Diffusion Policy: Preserving Multimodal Robot Actions through Label-Free Noise Assignment

不可混溶扩散策略:通过无标签噪声分配保留多模态机器人动作
Zhang, Xiao, Chen, Yuxin, Liang, Zhixuan, Zhan, Guojian, Li, Chenran, Xu, Chenfeng, Tomizuka, Masayoshi, Li, Yiheng
Abstract
When diffusion policies were first introduced, they were expected to recover multi-modal action distributions. However, we find this expectation does not always hold, as diffusion policies often collapse to a single modality even when we guarantee the balance of dataset modalities and exact within-batch symmetry. Our analysis indicates that independent action-noise pairing contributes to this failure by increasing mixing and crossing among diffusion paths, which can produce averaged denoising responses and suppress modality-specific behavior. This issue is especially severe in robot planning, where action spaces are dense and low-dimensional, significantly increasing such mixing and crossing. To alleviate this problem, we propose Immiscible Diffusion Policy, a label-free training-time add-on to diffusion policy that uses action-noise assignment to preserve relatively distinct noise-to-action routes without modifying the policy architecture or inference procedure. Across five simulated and two real-world humanoid manipulation tasks spanning state, RGB, and point-cloud observations, our method significantly improves the policy's preservation of action modalities while maintaining strong task performance. It increases the proportion of the non-dominant modality by 6.0x-14.6x across three two-modality tasks and recovers demonstrated modalities that are entirely absent from vanilla policy rollouts on both four-modality tasks. These results demonstrate that Immiscible Diffusion Policy provides a simple yet robust approach to preserving action multi-modality in general robot learning tasks.

当扩散策略首次被引入时,人们期望其能够恢复多模态动作分布。然而,我们发现这一期望并不总是成立,因为扩散策略往往会崩溃为单一模态,即使我们保证数据集模态的平衡和批内对称性。我们的分析表明,独立的动作-噪声配对导致了这一失败,增加了扩散路径之间的混合和交叉,这可能产生平均去噪响应并抑制模态特定行为。这个问题在机器人规划中尤为严重,因为动作空间是稠密且低维的,显著增加了这种混合和交叉。为了解决这个问题,我们提出了不可混溶扩散策略(Immiscible Diffusion Policy),这是一种在训练时无标签的附加方法,通过动作-噪声分配来保留相对独特的噪声到动作的路径,而无需修改策略架构或推理过程。在五个模拟和两个真实世界的人形操作任务中,我们的方法显著提高了策略对动作模态的保留,同时保持了强大的任务性能。在三个双模态任务中,非主导模态的比例增加了6.0倍至14.6倍,并在两个四模态任务中恢复了在普通策略回滚中完全缺失的示范模态。这些结果表明,不可混溶扩散策略为在一般机器人学习任务中保留动作多模态提供了一种简单而稳健的方法。

TempoBridge: Language-Guided Tempo Control for Vision-Language-Action Policies

TempoBridge:基于语言的节奏控制用于视觉-语言-动作策略
Lee, Yeonseo, Shin, Hyosup, Hwang, Guebin, Jo, Sungho
Abstract
Vision-Language-Action (VLA) models are effective at understanding what task to perform, but provide limited control over how it should be executed, such as moving quickly or slowly. We introduce TempoBridge, a lightweight framework that uses frozen VLA representations to modulate actions according to tempo cues in the instruction at each task phase, without additional tempo-conditioned robot demonstrations or tempo-specific base-policy fine-tuning. TempoBridge extracts tempo cues from contextual VLM representations, aligns them with task progress through a causal phase router, and modulates nominal motion commands during execution. Across LIBERO tasks, TempoBridge improves Tempo Success Rate from 52.6% to 89.7% under canonical tempo instructions while retaining high task success. It also preserves near-baseline performance when no tempo cue is present and generalizes to unseen tempo expressions without additional training. Experiments on a physical robot further demonstrate language-conditioned tempo modulation in real-world manipulation.

RobotAPO: Adversarial Physics Preference Optimization for Robotic Manipulation Video Generation

RobotAPO:用于机器人操控视频生成的对抗物理偏好优化
Li, Kerui, Jing, Zhe, Huang, Chenyi, Wang, Xiaofeng, Zhu, Zheng, Cui, Haoming, Huang, Huaibo
Abstract
Robotic manipulation videos are increasingly used as visual plans for embodied agents, but optimizing purely for visual plausibility often fails to capture the fragile physical manifold of real-world interactions. Even minor physics-violating errors at the interaction boundary, such as interpenetration or premature object motion, can completely invalidate the inferred timing and pose needed for downstream execution. Because standard supervised fine-tuning lacks the direct pressure to penalize these localized failures, we introduce AgiBot-PhysPref. This rigorously curated 10,000-sample preference dataset isolates condition-matched physics violations, turning the generator's own failure distribution into a foundational signal for physical consistency. Building upon this, we propose RobotAPO, an adversarial physics preference optimization framework operating in the continuous flow-matching denoising space. To prevent the policy from merely memorizing static curated failures, RobotAPO employs a lightweight adversarial counterfactual proposer that learns a condition-dependent, physical-failure-biased direction in denoising space. This encourages the model to explore and better respect the physical interaction boundary, all while maintaining a pure prompt-and-reference inference interface without requiring external structural conditioning. Comprehensive evaluations demonstrate that explicitly correcting these localized physics violations improves downstream robot execution from generated videos. On held-out AgiBot conditions, RobotAPO outperforms the strongest controlled internal baseline in physical consistency by 6.8% hard score and 10.0% soft score. Crucially, in real-robot replay, it translates these physical-consistency gains into a 37.4% relative improvement in task success over the strongest controlled internal baseline.

Detecting such activation is difficult because malicious behavior can comprise individually plausible actions, while unfamiliar tasks introduce legitimate changes in observations and behavior. We introduce TMT, a runtime backdoor detector based on Token Manifold and latent Transition modeling. Trained on benign rollouts, its two branches assess input-token structure and prediction errors in adjacent-layer latent dynamics. A suspicious rollout identified by the token manifold branch, once confirmed through latent deviations, guides transition selection for subsequent monitoring. We further explore policy purification through self-distillation: a frozen copy of the backdoored policy provides benign-input actions to supervise a student on paired benign and triggered observations, without requiring a separate clean reference policy. For evaluation, we adapt traditional backdoor detectors and repurpose anomaly and failure detection methods as VLA backdoor detectors. In a post-hoc comparison with ten baselines, TMT achieves state-of-the-art backdoor detection performance on unseen tasks across three VLA backdoor attacks.

带有后门的视觉-语言-动作(VLA)策略在触发器出现时可以保持良性的任务表现,同时产生恶意行为。检测这种激活是困难的,因为恶意行为可能由单独合理的动作组成,而不熟悉的任务则会引入观察和行为的合法变化。我们提出了TMT,一种基于Token Manifold和潜在转移建模的运行时后门检测器。TMT在良性回放上进行训练,其两个分支评估输入标记结构和相邻层潜在动态中的预测误差。通过标记流形分支识别的可疑回放,一旦通过潜在偏差确认,将指导后续监控的转移选择。我们进一步探索通过自蒸馏进行策略净化:冻结的后门策略副本提供良性输入动作,以监督在配对的良性和触发观察上的学生,而无需单独的干净参考策略。为了评估,我们调整了传统的后门检测器,并将异常和故障检测方法重新用于VLA后门检测器。在与十个基线的后验比较中,TMT在三个VLA后门攻击的未见任务上实现了最先进的后门检测性能。我们的项目页面可在 https://zzr42.github.io/tmt/ 上访问。

Precise SE(3) End-Effector Tracking in Whole-Body Humanoid Control

全身类人控制中的精确 SE(3) 末端执行器跟踪
Seo, Joohwan, Guo, Xiaofeng, Cao, Jinkun, Horowitz, Roberto, Duan, Rocky, Shi, Guanya, Sreenath, Koushil
Abstract
Precise end-effector tracking during humanoid whole-body motion is challenging due to floating-base oscillations, gravity, dynamic coupling, and locomotion-induced disturbances. We propose ResGAC, a whole-body humanoid controller for precise end-effector pose tracking that combines geometric admittance control (GAC) with residual reinforcement learning. GAC provides structured $\SE$ task-space feedback and generates nominal arm joint-position targets, while residual RL compensates for unmodeled dynamics and coordinates locomotion and balance in the shared joint-position action space. The left-invariant geometric formulation allows the same GAC law to be used across manipulation reference frames. This enables the use of a ground-attached heading frame that preserves planar locomotion while removing pelvis roll, pitch, and heave from the manipulation reference, thereby reducing reference-induced end-effector motion during locomotion. ResGAC is validated on a real Unitree G1 humanoid. Across four standing end-effector tracking benchmarks, ResGAC consistently outperforms representative baselines, including SONIC, achieving lower translational and rotational errors. Real-world experiments further demonstrate reduced propagation of pelvis motion to the desired end-effector pose using the proposed ground-attached heading frame. ResGAC achieves $90\%$ success in a standing peg-in-hole task compared with $50\%$ for SONIC, and accurate world-frame $\SE$ end-effector pose tracking during lower-body motion. Experimental videos are included in the supplementary material and are also available on the project website: https://resgac.github.io/ResGAC-website/.

在类人机器人全身运动中,精确的末端执行器跟踪面临着浮动基座振荡、重力、动态耦合和运动引起的干扰等挑战。我们提出了 ResGAC,一种用于精确末端执行器姿态跟踪的全身类人控制器,它结合了几何导纳控制(GAC)和残差强化学习。GAC 提供结构化的 $ ext{SE}$ 任务空间反馈,并生成名义臂关节位置目标,而残差强化学习则补偿未建模的动态,并在共享的关节位置动作空间中协调运动和保持平衡。左不变几何公式允许在不同的操作参考框架中使用相同的 GAC 法则。这使得可以使用一个与地面相连的朝向框架,在保持平面运动的同时,从操作参考中去除盆骨的滚转、俯仰和升降,从而减少运动过程中参考引起的末端执行器运动。ResGAC 在真实的 Unitree G1 类人机器人上进行了验证。在四个站立末端执行器跟踪基准测试中,ResGAC 一直优于代表性的基线,包括 SONIC,达到了更低的平移和旋转误差。现实世界的实验进一步证明了使用所提出的地面附着朝向框架可以减少盆骨运动对期望末端执行器姿态的传播。在站立的插销入孔任务中,ResGAC 的成功率达到 $90\%$,而 SONIC 仅为 $50\\%$,并在下肢运动中实现了准确的世界框架 $ ext{SE}$ 末端执行器姿态跟踪。实验视频已包含在补充材料中,并可在项目网站上获得:https://resgac.github.io/ResGAC-website/。

Abstract
The future of autonomous robots in human-oriented environments depends on their ability to navigate in the absence of prebuilt maps; exploiting navigational aids, such as navigational signs, designed by humans for humans is critical for enabling autonomy. This manuscript introduces a unique dataset collected using a handheld device, at various public spaces across Singapore, representing environments that humans frequent daily, and focusing on sign-centric decision making for mapless navigation. The dataset includes RGB, sparse depth, odometry and IMU measurements of scenarios centered around navigational signs and the complex environments where they are placed. Additionally, we provide 56 long-horizon navigation missions and over 450 sign-centric scenarios. All data is provided in a human- readable format, as well as utility scripts for conversion to ROS 2. Lastly, we provide venue maps and GPS aligned scene graphs of the test environments. We discuss the potential use cases for this dataset.

Sparse Feature Policy Unlearning Mitigates State Hallucination in Vision-Language-Action Models

稀疏特征策略遗忘缓解视觉-语言-动作模型中的状态幻觉
Lee, Jiho, Park, Jeongeun, Choi, Heayoun, Kim, Taekyung, Kim, Eunwoo
Abstract
Vision-Language-Action (VLA) models have shown strong generalization in robotic manipulation by leveraging rich representations from pretrained vision-language models. However, their deployment in real-world environments remains limited by recurring unreliable behaviors. In this work, we study state hallucination, a recurring failure pattern in which a VLA continues acting as if an unrealized robot-object state had been achieved. Our analyses find that state hallucination coincides with weakened attention to task-relevant visual regions, and a mechanistic interpretation via sparse autoencoders reveals that hallucination-associated sparse features are activated when these failures occur. Based on this analysis, we propose SOUL (Sparse feature pOlicy UnLearning), which selectively unlearns policy knowledge associated with state hallucination behaviors, where sparse features identified from hallucination failures and successful behaviors serve as explicit forgetting and retention targets, respectively. Experiments across VLA architectures in simulated and real-world environments show that our method substantially reduces hallucinated failures and improves task success without substantially compromising the existing manipulation capabilities. These results suggest that interpretable feature analysis provides a practical basis for selectively modifying undesirable knowledge in robot policies.

Not All Uncertainty Matters: Simulation-in-the-Loop Fast-Slow Reasoning for Decision-Critical Autonomous Driving System

并非所有的不确定性都重要:决策关键型自动驾驶系统的循环仿真快慢推理
Chen, Jiayi, Wang, Shuai, Zhu, Guangxu, Ng, Derrick Wing Kwan, Xu, Chengzhong, Huang, Kaibin
Abstract
Large vision-language models (VLMs) provide powerful open-world perception and reasoning for autonomous driving, but their high computational cost and inference latency make continuous cloud-side use impractical. This motivates fast--slow collaboration, where efficient onboard modules handle real-time perception and control while cloud models provide high-level reasoning only when needed. The key challenge is deciding when cloud reasoning should influence time-critical driving decisions. Existing methods often rely on perception uncertainty, heuristic triggers, or resource-driven policies, without assessing whether resolving an uncertainty will improve planning. We propose \textbf{SIGMA}, a simulation-in-the-loop framework for task-oriented fast--slow collaboration. SIGMA embeds the planner into uncertainty assessment and evaluates how plausible scene realizations under semantic and geometric uncertainty affect feasible trajectories and planning cost. Based on these outcomes, it estimates the expected reduction in planning cost from resolving uncertainty. We further introduce expected planning gain (EPG), a decision-level metric for cloud invocation, cloud-guidance integration, and request prioritization under deadline and resource constraints. Experiments in CARLA show that SIGMA reduces unnecessary cloud interactions while improving planning, efficiency, and navigation success in static and dynamic obstacle scenarios. Compared with fixed-period collaboration, SIGMA reduces unnecessary cloud interactions by 50\%, improves navigation success by more than 6\%, and cuts finish time by up to 26.2\% in dynamic scenarios.

Contact-Aware Imitation Learning Through Contact Factorization

通过接触因子分解的接触感知模仿学习
Hong, Jiho, Song, Daeun, Kim, Sanghyun, Seo, Mingyo
Abstract
Generalizable contact-rich manipulation requires robots to preserve intended task behavior while adapting its physical realization to changing contact conditions. However, interaction forces can vary substantially with small changes in surface geometry, orientation, and friction, making policies trained directly on raw force measurements difficult to transfer beyond demonstrated conditions. We introduce FACE, a contact-factorized imitation learning framework that separates intended task behavior from environment-dependent contact factors. Our representation expresses interaction forces in normalized, contact-relative coordinates, while a learned contact-normal estimator and an online friction estimator infer the local contact normal and effective friction scale. Together, these estimators enable force observations to be encoded and policy outputs to be decoded into physical motion and force commands during execution. In this way, FACE adapts execution to current contact conditions while preserving the intended task behavior, without updating the policy parameters. We evaluate FACE on real-robot contact-rich manipulation under unseen variations in surface properties and geometry, demonstrating robust generalization across contact conditions through controlled comparisons with variants that adapt prior approaches to our setting.

MagCilia: A Compact Magnetociliary Tactile Sensor with 3D Force Sensing for Robotic Contact Perception and Grasping Feedback

MagCilia:一种紧凑型磁性纤毛触觉传感器,具有用于机器人接触感知和抓取反馈的三维力感测功能
Feng, Yu, Wu, Hao, Guo, Haotian, Liu, Haoming, Su, William, Guo, Jingxiang, Li, Jiankun, Tomizuka, Masayoshi, Li, Wen Jung, Zhou, Jianshu
Abstract
Robotic grasping and surface exploration benefit from simultaneous measurement of normal and tangential forces and from surface information obtained through contact. Here, we present a compact magnetociliary tactile sensor (MagCilia) that combines a flexible magnetic-cilia structure with a Hall sensor for 3D force sensing. Quasi-static finite element analysis is used to investigate structural deformation and magnetic responses under multidirectional loading. To reconstruct forces from the coupled magnetic channels, we propose causal history fusion regression (CHFR), which combines current magnetic-field measurements with their recent changes. Five-fold cross-validation grouped by calibration record yields root-mean-square errors of 0.40, 0.57, and 0.69 N for Fx, Fy, and Fz, respectively, with corresponding coefficients of determination of 0.93, 0.90, and 0.92. Robotic experiments demonstrate tangential-force-guided gripper adjustment and multi-axis load monitoring under external perturbations. Frequency-domain features of the reconstructed forces distinguish six surface categories with 99.39% accuracy in three-fold cross-validation grouped by acquisition session. An online robotic demonstration additionally identifies all six tested surfaces. These results demonstrate 3D force reconstruction, grasping feedback, and surface recognition using a single compact tactile unit.

Targeted Modality Dropout for Real-Robot Manipulation Robust to Intermittent Vision Loss

针对间歇性视觉丧失的真实机器人操作的目标模态丢弃
Shikada, Genki, Osamura, Kazuki, Ide, Masaru, Ogata, Tetsuya, Suzuki, Kanata
Abstract
Imitation learning policies that integrate multiple sensory modalities are prone to overreliance on a dominant modality, such as vision, during training, which can disrupt policy execution when that modality is lost at inference time. In this paper, we introduce Targeted Modality Dropout (TMD), in which the dependence on each modality is estimated using attention and the most dominant modality is selectively dropped. This is combined with entropy regularization over the dependence distribution. Through real-robot evaluation using a bimanual manipulator, we show that under vision loss the success rate of the baseline policy drops substantially, whereas TMD sustains task execution. In contrast, a conventional dropout that selects the dropped modality at random, without the entropy regularization, fails on many tasks even without vision loss.

Point It, Strike It: Direction-Conditioned Dynamic Manipulation of Deformable Linear Objects

指向它,击打它:方向条件下可变形线性物体的动态操控
Yang, Yi, Fei, Xiang, Wang, Lehong, Dai, Zilin, Li, Ruogu, Cai, Jiting, Chang, Liyao, Yang, Xinyi, Kou, Henry, Fu, Ruijie, Li, Lu, Choset, Howie
Abstract
Goal-conditioned dynamic manipulation of deformable linear objects has mainly specified goals as positions for a rope tip to reach. Many tasks, however, depend on how the tip arrives. We therefore study single-swing rope striking with goals that specify the tip's 3D position and arrival direction, across the workspace and on different ropes. This is challenging because rope dynamics are hard to model, no demonstrations exist, distinct swings reach the same goal with different reliability, and the sim-to-real gap extends beyond the rope. To address these challenges, we extend the state-of-the-art DLO simulator DeformX with GPU acceleration, a stable Cosserat rod solver, and a cross-flow aerodynamic model, yielding DeformX2.0, which is more than $20{,}000\times$ faster. We then propose TRACE (Trace-rooted Adaptive Cross-Entropy), which generates striking data by warm-starting each new target from the stored swing whose tip path passes closest to it. Its cost penalizes rope bending and abrupt tip motion to favor repeatable swings. A conditional flow-matching policy trained on this data reaches 92.1% accuracy in simulation. Finally, we propose RECAP (Residual Calibration Policy), which fits the simulator's rope and rig parameters to a few calibration swings and adapts actions with a correction policy trained in simulation. On a real robot, across three ropes, RECAP raises success within 5cm from 72% to 87% for position goals, and within 10cm and 10{\deg} from 50% to 79% for goals that also specify the arrival direction.

Adaptive Code Generation for Controlling Robots

用于控制机器人的自适应代码生成
Flerlage, Justus, Wittkopp, Thorsten, Acker, Alexander, Kao, Odej
Abstract
Deploying robots as Complex Adaptive Systems (CAS) in unknown and dynamic environments necessitates a transition from rigid command libraries toward intention-based autonomy, as natural language represents the only medium capable of articulating complex goals beyond the capacity of finite instruction sets. While Large Language Models (LLMs) offer a path toward natural language goal description, their integration introduces significant challenges: the formalization gap between imprecise intentions and executable actions, the taxonomy gap induced by unpredictable environments, and the challenge of maintaining temporal state and progress awareness. This work introduces an architectural framework that enables robotic control by leveraging generative AI. The system follows a dual-AI design: an LLM translates high-level intentions into executable program code restricted to a formal robotic library and constrained by verifiable syntax, while a Vision-Language Model (VLM) provides semantic grounding via a distillation process. To ensure robustness, the framework incorporates environment-driven replanning triggers based on geometric and semantic thresholds, complemented by continuous runtime monitoring and an adaptive planning loop. Benchmarked across frontier models, our framework architecture demonstrates that grounding generative AI in a reactive, constrained loop enables robust fulfillment of complex intentions in dynamic and unknown environments.

NAViLoss: An Underwater Navigation-Aware Dual-Residual Objective for Physics-Consistent Learning

NAViLoss:一种水下导航感知的双残差目标函数用于物理一致性学习
Sahoo, Arup Kumar, Klein, Itzik
Abstract
Autonomous underwater vehicles (AUVs) commonly rely on inertial navigation systems (INS) aided by Doppler velocity logs (DVLs) for reliable underwater navigation. Accurate DVL velocity estimation is therefore essential for successful operation. Recent learning-based methods have demonstrated improved DVL velocity estimation, particularly under degraded measurement conditions. However, their training objectives typically rely on conventional regression losses that are highly sensitive to large residuals and corrupted observations. Additionally, they do not explicitly account for the physical consistency and measurement uncertainty associated with the underlying sensing process. To address these limitations, this paper introduces navigation-aware loss (NAViLoss), a robust and uncertainty-aware objective function for learning-based AUV velocity estimation. NAViLoss jointly penalizes the velocity-estimation residual in the navigation-state domain and the beam-consistency residual in the DVL measurement domain. Its bounded formulation limits the influence of large residuals, while an adaptive mechanism regulates the uncertainty in beam geometry. Furthermore, NAViLoss is integrated with a DeepONet architecture to form a novel NAVi-DeepONet model for seamless estimation of an underwater vehicle's velocity. Lastly, our model is evaluated using approximately 10,000m of semi-synthetic AUV experimental data collected during multiple real-world sea trials. Experimental results demonstrate a 44% improvement in velocity-estimation accuracy compared with conventional and learning-based baselines. These results demonstrate the effectiveness of navigation-aware and uncertainty-adaptive loss design for robust learning-based underwater velocity estimation.

自主水下航行器(AUV)通常依赖于惯性导航系统(INS)和多普勒速度计(DVL)辅助进行可靠的水下导航。因此,准确的DVL速度估计对于成功操作至关重要。近期基于学习的方法在DVL速度估计方面显示出了改善,特别是在测量条件恶化的情况下。然而,它们的训练目标通常依赖于传统的回归损失,这些损失对大残差和受损观测值高度敏感。此外,它们并未明确考虑与基础传感过程相关的物理一致性和测量不确定性。为了解决这些局限性,本文提出了一种导航感知损失(NAViLoss),这是一种稳健且具不确定性感知的目标函数,用于基于学习的AUV速度估计。NAViLoss在导航状态域中联合惩罚速度估计残差,并在DVL测量域中惩罚波束一致性残差。其有界的形式限制了大残差的影响,而自适应机制则调节波束几何的测量不确定性。此外,NAViLoss与DeepONet架构相结合,形成了一种新颖的NAVi-DeepONet模型,实现水下航行器速度的无缝估计。最后,我们的模型使用在多次真实海试中收集的约10,000米半合成AUV实验数据进行了评估。实验结果表明,与传统和基于学习的基线相比,速度估计精度提高了44%。这些结果证明了导航感知和不确定性自适应损失设计在稳健的基于学习的水下速度估计中的有效性。

Do Better Visual Representations Always Lead to Better End-to-End Autonomous Driving?

更好的视觉表示是否总是能带来更好的端到端自主驾驶?
Zhang, Zihao, Tian, Haochen, Li, Tianyu, Jing, Changhui, He, Jingliang, Ye, Naisheng, Pu, Ziyuan, Yang, Zhenjie
Abstract
Visual foundation models (VFMs) are increasingly integrated into end-to-end autonomous driving for their powerful representations, yet it remains unclear when these representations improve driving performance. To investigate this question, we introduce ViRA, a planner-agnostic visual representation alignment framework that keeps the planner architecture and inference cost unchanged. Our study reveals three findings: (1) VFM-guided visual representations consistently improve driving performance across diverse end-to-end planners, with gains extending to zero-shot closed-loop evaluation. (2) The choice of VFM target matters for planning performance, and alignment to a different VFM can further benefit planners with pre-trained VFM encoders. (3) Auxiliary perception supervision reduces sensitivity to VFM target selection, narrowing the EPDMS spread across five targets from 2.7 to 0.5 points and potentially compensating for less effective VFM targets. Guided by these findings, we develop ViRA-Diffusion, a diffusion-based planner trained without auxiliary perception supervision, which achieves 92.3 EPDMS on NAVSIM v2 navtest, outperforming recent methods in our comparison by at least 1.9 points. The results motivate jointly considering target selection and planner supervision when integrating VFMs into end-to-end autonomous driving.

视觉基础模型(VFMs)因其强大的表示能力而越来越多地被整合到端到端自主驾驶中,但这些表示何时能改善驾驶性能仍不清楚。为了解决这个问题,我们引入了ViRA,一个与规划器无关的视觉表示对齐框架,它保持规划器架构和推理成本不变。我们的研究揭示了三个发现:(1)VFM引导的视觉表示在多种端到端规划器中始终改善驾驶性能,增益甚至扩展到零样本闭环评估。(2)VFM目标的选择对规划性能至关重要,与不同VFM的对齐可以进一步使带有预训练VFM编码器的规划器受益。(3)辅助感知监督减少了对VFM目标选择的敏感性,将五个目标之间的EPDMS差距从2.7缩小到0.5分,并可能弥补效果较差的VFM目标。根据这些发现,我们开发了ViRA-Diffusion,一个在没有辅助感知监督的情况下训练的基于扩散的规划器,在NAVSIM v2 navtest上达到了92.3的EPDMS,至少比我们比较中的最新方法高出1.9分。结果促使我们在将VFMs整合到端到端自主驾驶时共同考虑目标选择和规划器监督。结果和演示可在https://github.com/OpenDriveLab/ViRA获取。

RoboPace: Contact-Aware Time-Optimal Retiming for Action-Chunk Policies

RoboPace:面向接触感知的时间最优重定时用于动作块策略
Shirasaka, Mimo, Ohkawa, Takehiko, Okubo, Takuya, Scianca, Nicola, Matsushima, Tatsuya, Ota, Kei
Abstract
Robot manipulation data collection has been shifting from teleoperation toward robot-free demonstrations, through interfaces such as the Universal Manipulation Interface (UMI) or directly from human hands. Vision-Language-Action (VLA) policies trained on such data inherit the demonstrator's timing. Yet human timing does not directly transfer to robots: compliant hands tolerate fast contact, whereas robots may overshoot due to actuator and tracking limitations; conversely, robots can move faster in free space. This motivates a unified approach that reconciles execution speed with contact safety. We present RoboPace, an online retiming layer that preserves the policy's geometric path while adapting its timing, respecting the target robot's kinematic and dynamic constraints. It adapts execution speed based on predicted contact, jointly accounting for contact-dependent speed limits and the robot's motion constraints. The method requires no policy retraining and operates in real time. Across three contact-rich tasks on a dual-arm robot, faster uniform execution and physical-limit-only retiming largely fail. RoboPace instead achieves higher overall success than slow uniform execution while completing four of five commands in approximately half the time, retaining the reliability of slow execution without its time cost.

机器人操作数据收集正从遥控操作转向无机器人演示,通过诸如通用操作接口(Universal Manipulation Interface, UMI)或直接来自人手的接口。基于此类数据训练的视觉-语言-动作(Vision-Language-Action, VLA)策略继承了演示者的时序。然而,人类的时序并不能直接转移到机器人上:顺应性手部可以容忍快速接触,而机器人由于执行器和跟踪限制可能会超出预期;相反,机器人在自由空间中可以移动得更快。这促使我们提出一种统一的方法,以调和执行速度与接触安全性。我们提出了RoboPace,这是一种在线重定时层,它在保留策略几何路径的同时调整其时序,遵循目标机器人的运动学和动力学约束。该方法基于预测的接触情况调整执行速度,同时共同考虑依赖接触的速度限制和机器人的运动约束。该方法无需重新训练策略,并且实时运行。在双臂机器人上进行的三个接触丰富的任务中,快速均匀执行和仅基于物理限制的重定时大多未能成功。相比之下,RoboPace在完成五个命令中的四个时,整体成功率高于缓慢均匀执行,并且所需时间大约为其一半,保持了缓慢执行的可靠性而不增加时间成本。

YUBI-STAG: Contact and Semantic-Rich Alignment for VLAs via Automated Video-Language Grounding

YUBI-STAG:通过自动化视频语言基础实现的接触与语义丰富对齐的视觉-语言-动作模型
Tateno, Masatoshi, Ohkawa, Takehiko, Wu, Yueh-Hua, Li, Hanlong, Matsushima, Tatsuya, Sato, Yoichi, Ota, Kei
Abstract
Vision-Language-Action (VLA) models acquire broad manipulation capabilities via large-scale pretraining, yet eliciting them through language requires fine-grained alignment between instructions and physical interactions. Existing robot demonstrations typically provide only coarse task descriptions, omitting how actions are executed, including which gripper acts, which object is contacted, and how it is grasped and moved. We introduce YUBI-STAG, a framework for Spatio-Temporal Annotation and Grounding that automatically enriches manipulation demonstrations with interaction-rich semantics to align pretrained VLAs with fine-grained manipulation language. Combining contact-object segmentation with vision-language models, YUBI-STAG annotates object identities, attributes and states, per-gripper actions, bimanual coordination, and spatially grounded interactions. To address YUBI-STAG's reliance on localized sequences and multi-stage VLM inference, we distill it into YUBI-VLM. YUBI-VLM directly recovers action structure and annotations from raw, unsegmented video in few inference calls and operates from wrist views alone. We evaluate both frameworks on YUBI-STAG-Bench across temporal, semantic, and spatial grounding tasks. YUBI-VLM retains much of YUBI-STAG's annotation accuracy with fewer inference calls and shorter runtime while generalizing to unseen manipulations. Finally, post-training VLA policies on these annotations aligns them with fine-grained language and contact-aware structure. Bimanual experiments demonstrate improved performance and instruction following, including control over object identity, acting gripper, target location, and spatial relations absent from original labels.

视觉-语言-动作(VLA)模型通过大规模预训练获得广泛的操作能力,但通过语言引导它们需要指令与物理交互之间的细粒度对齐。现有的机器人演示通常仅提供粗略的任务描述,省略了动作是如何执行的,包括哪个夹持器在作用、哪个物体被接触,以及如何抓取和移动。我们提出了YUBI-STAG,一个用于时空注释和基础的框架,能够自动丰富操作演示的交互语义,以便将预训练的VLA与细粒度的操作语言对齐。YUBI-STAG结合了接触物体分割与视觉-语言模型,注释物体的身份、属性和状态、每个夹持器的动作、双手协调以及空间基础的交互。为了解决YUBI-STAG对局部序列和多阶段视觉语言模型推理的依赖,我们将其提炼为YUBI-VLM。YUBI-VLM能够在少量推理调用中直接从原始未分割视频中恢复动作结构和注释,并仅依赖手腕视角进行操作。我们在YUBI-STAG-Bench上评估了这两个框架,涵盖时间、语义和空间基础任务。YUBI-VLM在保持YUBI-STAG注释准确度的同时,减少了推理调用次数和运行时间,并能够推广到未见过的操作。最后,在这些注释上进行后训练的VLA策略使其与细粒度语言和接触感知结构对齐。双手实验表明,在控制物体身份、作用夹持器、目标位置和原始标签中缺失的空间关系方面,性能和指令遵循得到了改善。

{\Delta}WAM: Distilling Action Tangent Fields into World Action Models

{ ext{Δ}}WAM:将动作切线场提炼为世界动作模型
Wu, Ke, Huang, Hanwen, Gu, Bo, Zhang, Kaizhao, Meng, Xiangting, Zheng, Yupeng, Xu, Zijun, Zhao, Jieru, Ding, Wenchao
Abstract
World Action Models (WAM) improve robot policies by augmenting sparse action supervision with dense future prediction. However, much of the predictable future is dominated by appearance and scene persistence rather than action-dependent dynamics. We observe that several recent WAM designs, including optical flow, motion-centric representations, and latent actions, can be understood from a common perspective in which world supervision becomes more efficient as it contains a higher proportion of action-relevant variation. Based on this insight, we introduce Action Tangent Fields, which reformulate world supervision through a local Taylor expansion of how actions induce changes in future dynamics. We represent future dynamics in Residual-VAE space, where the future latent remains recoverable from the current latent and its residual, and use a strong action-conditioned world model (ACWM) to probe the local correspondence between action variations and residual-world variations. This local first-order structure is distilled into the WAM to guide its denoising supervision toward dynamics that are more tightly coupled to action, rather than merely predictable from appearance. Across LIBERO-Plus, RoboTwin, and RoboTwin2.0-Plus, our method consistently improves robustness to lighting, background, camera, layout, and other environmental perturbations. Despite using no large-scale embodied pretraining, it achieves stronger robustness under several distribution shifts than pretrained policies. We further distill multi-step VideoDiT denoising into a single step for efficient inference. Our results suggest that effective WAM supervision should remain information-rich while concentrating its predictive capacity on the directions along which actions change the future.

世界动作模型(World Action Models, WAM)通过将稀疏的动作监督与密集的未来预测相结合,改善了机器人策略。然而,可预测的未来大部分受外观和场景持久性主导,而非依赖于动作的动态。我们观察到,近年来的几种WAM设计,包括光流(optical flow)、运动中心表示(motion-centric representations)和潜在动作(latent actions),可以从一个共同的视角理解,即世界监督在包含更高比例的与动作相关的变化时变得更加高效。基于这一见解,我们引入了动作切线场(Action Tangent Fields),通过局部泰勒展开重新构造世界监督,描述动作如何引发未来动态的变化。我们在残差变分自编码器(Residual-VAE)空间中表示未来动态,其中未来潜在状态可以从当前潜在状态及其残差中恢复,并使用强大的动作条件世界模型(Action-conditioned World Model, ACWM)探测动作变化与残差世界变化之间的局部对应关系。这种局部的一阶结构被提炼到WAM中,以引导其去噪监督朝向与动作更紧密耦合的动态,而不仅仅是从外观中可预测的动态。在LIBERO-Plus、RoboTwin和RoboTwin2.0-Plus上,我们的方法在光照、背景、相机、布局和其他环境扰动下始终提高了鲁棒性。尽管没有使用大规模的具身预训练,但在多个分布转移下,它的鲁棒性超过了预训练策略。我们进一步将多步视频去噪(VideoDiT)提炼为单步,以实现高效推理。我们的结果表明,有效的WAM监督应保持信息丰富,同时将其预测能力集中在动作改变未来的方向上。

AeroEval: Staged Program and Execution Validation for AI-Generated Drone Missions

AeroEval:针对AI生成无人机任务的分阶段程序和执行验证
Astu, Kautuk, Rabha, Naina, Simmhan, Yogesh
Abstract
Large Language Models (LLMs) can generate drone programs from natural-language mission descriptions, but syntactically valid programs may still violate user intent, environmental constraints, and mission-level behavior. This problem is pronounced in cyber-physical applications, where correctness depends on the interaction among generated code, mobile sensing, environmental geometry, event-driven analytics, and physical execution. Existing drone code-generation systems primarily use prompt guardrails or simulator outcomes and provide limited failure localization. We present AeroEval, an agent-assisted middleware for staged validation of AI-generated drone missions. AeroEval combines deterministic program analysis with context-grounded LLM agents. It first validates program syntax, platform API usage, and mission intent, and then evaluates the realized behavior using execution trajectories, mission requirements, and environmental context. Each stage returns structured failure information for iterative regeneration. In our evaluation using 20 navigation tasks and five analytical mission types over AirSim and Gazebo simulators, AeroEval improves navigation success from 55% to 95%. In a stagewise ablation study, our Code and Trajectory Validators by themselves achieve mean run-level success rates of 44% and 56%, respectively, while the full AeroEval pipeline achieves 88%; the stages detect complementary failures in program structure, API usage, mission intent, obstacle avoidance, altitude, coverage, and event-driven transitions and the guided regeneration corrects for them. Across the main analytics missions, AeroEval increases aggregate run-level success from 34% for one-shot AeroGen to 88% within the regeneration budget. These results demonstrate the benefit of combining program-level and execution-grounded agentic validation for AI-generated drone applications in the evaluated environment.

大型语言模型(LLMs)能够根据自然语言的任务描述生成无人机程序,但语法上有效的程序仍可能违反用户意图、环境约束和任务级行为。这一问题在网络物理应用中尤为突出,因为其正确性依赖于生成代码、移动感知、环境几何、事件驱动分析和物理执行之间的相互作用。现有的无人机代码生成系统主要依赖于提示保护措施或模拟器结果,并且提供的故障定位能力有限。我们提出了AeroEval,这是一种代理辅助的中间件,用于AI生成无人机任务的分阶段验证。AeroEval结合了确定性程序分析与基于上下文的LLM代理。它首先验证程序的语法、平台API的使用和任务意图,然后使用执行轨迹、任务要求和环境上下文评估实现的行为。每个阶段返回结构化的故障信息以便于迭代再生成。在我们使用20个导航任务和五种分析任务类型在AirSim和Gazebo模拟器上的评估中,AeroEval将导航成功率从55%提高到95%。在逐阶段消融研究中,我们的代码和轨迹验证器单独实现的平均运行级成功率分别为44%和56%,而完整的AeroEval管道实现了88%;各阶段检测到程序结构、API使用、任务意图、障碍物规避、高度、覆盖范围和事件驱动转换中的互补故障,并通过指导再生成进行修正。在主要分析任务中,AeroEval将一次性AeroGen的整体运行级成功率从34%提高到88%在再生成预算内。这些结果展示了在评估环境中结合程序级和执行基础的代理验证对于AI生成无人机应用的益处。

On-Demand Robotic Assembly via Differentiable Geometric Part Repair

基于可微几何部件修复的按需机器人装配
Schlafly, Millicent, Schaub, Fabio, Pais, Diogo Costa, Lelli, Luca, Dvorak, Janne, Colmont, Claire, Marti, Sven, Fuge, Mark D.
Abstract
Transitioning from a digital design to a robotic assembly process currently requires months of expert manual tuning to reconcile part geometries with robotic constraints. This paper presents an end-to-end, autonomous pipeline for the design and physical construction of bespoke wooden assemblies. A generative AI agent translates user prompts into initial 3D geometries, balancing the visual fidelity of the design with select physical constraints. The assemblability of the design is further improved by a gradient-based repair stage that backpropagates through a graph attention network surrogate to adjust component geometries. In addition to correcting for disjointed and overlapping components, we demonstrate hardware-specific corrections, differentiably optimizing the geometry of components to enable robot screwdriving for 86.7% of 60 novel natural language inputs, significantly outperforming prior work by a factor of ten. For ten of the structures, we physically demonstrate assemblability with two UR5e robots. This work marks a meaningful step toward on-demand robotic manufacturing, enabling the rapid production of customized, low-volume goods.

End-to-End Autonomous Generation of Human Assembly Plans

端到端自主生成人类装配计划
von Arx, Faustin Arion, Schlafly, Millicent, Fuge, Mark D.
Abstract
Turning a CAD design into an assembly plan is still largely done by hand, requiring engineers to reason about geometric feasibility, tool access, stability, and the ergonomics of human assembly. In this work, we encode long-established design for assembly (DfA) principles into a contained, end-to-end approach for generating assembly plans. Our approach takes only a mesh assembly and produces either a step-by-step assembly manual or a structured failure report, requiring no joint metadata, fastener annotations, or additional information. Four major components of a manufacturing plan are addressed autonomously: an assembly tool list, the assembly sequence and subassemblies, an assembly manual, and design feedback for improving assemblability. For determining the sequence plan, we systematically disassemble the object in a physics simulator and apply a cost function that encodes DfA principles. Manual generation, tool labelling, and assembly feedback rely primarily on multimodal large language models. Compared with a baseline that always removes the outermost part first from Tian et al., DfA-aware sequence planning reduces simulated assembly time, measured with a robot-arm assembly-time proxy, by 35% on 136 assemblies of 5 to 30 parts. The correct tool is selected for 88.6% of assembly steps. A vision-language model judge compares the generated manuals against ablated variants, identifying which page elements carry the information a reader needs. The presented approach and open-source code are available for use by engineers or AI agents looking to rapidly accelerate the creation of manufacturing plans for a given product design.

Enhancing Robotic Perception and Adaptability through Sensor Fusion and Origami-Inspired Designs

通过传感器融合和受折纸启发的设计增强机器人感知与适应性
Chandra, Namai, Jose, Jaison, Arya, Kavi, Kalyanakrishnan, Shivaram
Abstract
Compact mobile robots must recover scene geometry under changing lighting and surface texture while working within tight payload and cost limits. We present a compact mobile robot that uses origami-inspired wheels for locomotion and active control of its sensing geometry. As the wheels move between terrain-adaptive configurations, the changing chassis pitch sweeps a 2D LiDAR through intermediate elevations; held wheel positions provide a chosen viewing angle. An IMU accounts for chassis attitude, and a fusion node projects LiDAR returns into the RGB-D depth stream supplied to RTAB-Map. The arrangement uses the wheel actuation already present on a sub-300 USD, sub-2 kg prototype to extend the scanner's viewing geometry. We assess depth fusion in a textureless indoor corridor and an outdoor sunlit area, with three runs per sensor configuration in each setting. Mean full-frame invalid-depth fractions fell from 21% to 11% indoors and from 48% to 18% outdoors. The prototype combines improved depth coverage with a continuously adjustable LiDAR viewpoint using the same actuation that reconfigures its wheels.

Towards Accurate End-Effector Localization for UMI-Style Robotic Manipulation Teaching

面向UMI风格机器人操作教学的精确末端执行器定位
Zhang, Junjie, Zhang, Deteng, Xu, Zhisong, Sun, Bo, Li, Liuyang, Tian, Yihong, Yin, Jie
Abstract
Robot demonstration learning requires accurate and temporally complete end-effector localization during close-range manipulation and camera occlusion. Existing SLAM benchmarks emphasize navigation motions, whereas manipulation datasets prioritize policy learning over localization evaluation. We introduce MILD, a Manipulation-Interface Localization Dataset with real-world and simulation sequences. The real-world subset provides 86 sensor sequences from Insta360 X5 and Insight9 across 15 repeated tabletop tasks, calibration assets, and a per-execution robot end-effector reference trajectory. The simulation subset, MILD-Sim, extends task coverage in Isaac Sim for controlled manipulation-replay studies. Benchmarking visual-inertial and fiducial-aided systems on instrumented real-world recordings reveals large differences in both TCP-relative trajectory error and temporal coverage, even under the same nominal task. To support marker-augmented teaching workspaces without a pre-surveyed fiducial map, we present AprilVINS, which combines fisheye visual-inertial estimation with sequence-local AprilTag geometry and separates prior admission from guarded export of the jointly optimized state. On Insta360 AprilTag4 recordings, AprilVINS(full) under a unified protocol with sequence-specific profiles reaches millimeter-level SE(3)-aligned TCP-relative APE RMSE with high time completion and lower reported error than the tested routes under their respective protocols, whereas fisheye VIO without tag factors remains at centimeter scale. Ablations separate accuracy from exportability, and a MILD-Sim replay study provides task-specific tolerance references for interpreting those error magnitudes. Together, MILD and AprilVINS provide a diagnostic benchmarking framework for UMI-style demonstration collection. Code, datasets, and evaluation manifests will be released upon acceptance.

Juno: Taming Predictive Latents for Vision-Language-Action Models

Juno:驯化视觉-语言-动作模型的预测潜变量
Zhu, Yuchen, Xu, Chenyi, Zhang, Yulin, Xu, Gang, Zhu, Wentao
Abstract
Joint-embedding predictive architectures (JEPAs) predict masked or future observations in representation space, offering a natural source of predictive latents for vision-language-action (VLA) models. Yet making these latents useful across pretraining, policy learning, and deployment requires addressing three failures: mismatch with embodiment-specific control, interference with action learning, and teacher miscalibration under distribution shifts. We introduce Juno, a unified framework built around one action-conditioned JEPA that serves as a control-aligned representation backbone, a predictive teacher, and an adaptable dynamics model. During pretraining, we train it on embodiment-matched trajectories and use a dynamic CLS loss to transfer motion-weighted patch dynamics to a compact global state. During policy learning, we fuse current-frame JEPA patches into VLA perception and use a decoupled reasoning branch with separate transformation parameters to distill future latent states for action generation. During deployment, we adapt the world model on all observed transitions, including failed rollouts, freeze the adapted teacher, and re-align the policy on verified executions using LoRA adapters and a trainable action head, without expert corrections or task rewards. On SimplerEnv, Juno raises average success from $60.9\%$ to $68.5\%$ over Qwen3GR00T, the strongest baseline, and test-time adaptation further reaches $72.7\%$; on a real robot, it retains $70\%$--$75\%$ success under background, height, and object shifts where the base policy collapses to $0\%$.

联合嵌入预测架构(JEPAs)在表示空间中预测被遮蔽或未来的观察,为视觉-语言-动作(VLA)模型提供了一种自然的预测潜变量来源。然而,使这些潜变量在预训练、策略学习和部署中有效,需要解决三个问题:与具体体现控制的不匹配、对动作学习的干扰以及在分布变化下教师的误校准。我们提出了Juno,一个围绕一个基于动作条件的JEPA构建的统一框架,作为控制对齐的表示骨干、预测教师和适应性动态模型。在预训练期间,我们在与体现匹配的轨迹上进行训练,并使用动态CLS损失将运动加权的补丁动态转移到紧凑的全局状态。在策略学习期间,我们将当前帧的JEPA补丁融合到VLA感知中,并使用一个解耦的推理分支,具有独立的变换参数,以提炼用于动作生成的未来潜在状态。在部署期间,我们在所有观察到的转变上适应世界模型,包括失败的回滚,冻结适应后的教师,并使用LoRA适配器和可训练的动作头在经过验证的执行上重新对齐策略,而无需专家修正或任务奖励。在SimplerEnv上,Juno将平均成功率从60.9%提高到68.5%,超越了最强基线Qwen3GR00T,测试时适应进一步达到72.7%;在真实机器人上,它在背景、高度和物体变化下保持70%-75%的成功率,而基础策略则崩溃至0%。

Many Ways to Succeed: Diversity-Driven RL Fine-Tuning for VLA Generalization

多种成功之道:基于多样性的强化学习微调用于视觉-语言-动作泛化
Li, Haoru, Liu, Jinmei, Wang, Zhiyong, Li, Xiaoming, Sun, Zhenhong, Dong, Daoyi, Chen, Chunlin, Wang, Zhi
Abstract
Reinforcement learning (RL) fine-tuning improves vision-language-action (VLA) policies through closed-loop experience, yet generalization beyond the fine-tuning distribution remains limited. Our analysis reveals a selective reshaping of exploration: RL contracts behavior globally, yet diversifies successful trajectories, elicits success with fewer rollouts, and covers more of the latent task-valid solution space than supervised fine-tuning. Broader successful-mode coverage may provide alternative strategies under distribution shifts. Inspired by this, we introduce DRIVE (Diversity-driven RL fIne-tuning for VLA gEneralization), which turns successful-behavior diversity into an explicit RL objective. DRIVE groups rollouts under matched task conditions, compares their trajectories with temporal alignment, and derives a success-conditioned intrinsic reward from relative behavioral diversity. This design encourages broader coverage of feasible solutions without rewarding diverse failures or superficial timing differences. Across LIBERO-Plus, ManiSkill3, and RoboTwin 2.0, DRIVE improves the average out-of-domain (OOD) performance over vanilla RL fine-tuning by 5.3 points on $\pi_0$ and 2.0 points on $\pi_{0.5}$. On a dual-arm AgileX PiPER-X platform, DRIVE further increases average OOD success from 64.1% to 73.3% (+9.2 points), demonstrating gains that persist under physical deployment.

Borrowed Eyes: Markerless Nano-UAV Flight with an Active Quadruped Observer

借用的视角:无标记纳米无人机与主动四足观察者的飞行
Mora, Alejandro Lorite, Arapis, Dimitrios, Faíña, Andrés
Abstract
Nano unmanned aerial vehicles (nano-UAVs) can navigate confined spaces that larger robots cannot, but their payload capacity severely limits the sensors and compute available for self-localization in global navigation satellite system (GNSS)-denied environments. We present a vision-based system that localizes a nano-UAV from a quadruped robot with an arm-mounted camera. The quadruped tracks the drone, estimates its position in its own coordinate system using segmentation masks and depth, and transmits that position over a real-time radio link. To ensure continuous tracking, we developed a perception-aware nonlinear Model Predictive Controller (NMPC) that dynamically adjusts the quadruped's body and arm to maximize the drone's visibility, treating observation reliability as a primary control objective. Relying solely on this external estimate, the nano-UAV executed predefined trajectories from takeoff to landing with a median 3D localization error of 59 mm. The system demonstrates robustness against short visual occlusions by smoothly transitioning to onboard inertial flight when line-of-sight is temporarily lost.

Decoding Neural Population Dynamics through Robotic Analog

通过机器人类比解码神经群体动态
Chen, Wenhui, Tao, Jiyue, Cheng, Yitao, Shi, Yutong, Zhang, Feitian, Liang, Xitong, Liu, Ke
Abstract
Animal evidence shows that precise voluntary movements arise from rotational neural population dynamics in motor cortex, but their physical effects remain unknown. We developed a robotic analog of biological motor systems with artificial muscles, multimodal sensors, and a neural network controller trained via reinforcement learning. The robotic analog exhibited accurate movements, robustness to damage, and neural population dynamics akin to animals. This task-driven, embodied model illuminates the causal link between neural population dynamics and motor outcomes. We discovered that neural rotations generate oscillatory maneuvers orthogonal to the reaching direction, optimizing trajectory adjustments, which is confirmed by primate neural data. The model also revealed counterintuitive neural energy principles under sensor and motor redundancies, and striking Eureka moments during motor learning, bridging biological and artificial systems. These findings provide new perspectives on how neural dynamics contribute to accurate and flexible movement, inspiring future intelligent robots with animal-like mobility.

Tactile Reconstruction of Contact Task Frames and Forces for Hybrid Force/Motion Control

接触任务框架和力的触觉重建用于混合力/运动控制
Rapuano, Antonio, Orelli, Simone, Bazzana, Barbara, Franchi, Antonio, De Luca, Alessandro
Abstract
Hybrid force/motion control requires knowledge of the interaction force and of a task frame defining the force- and motion-controlled directions. These quantities are usually obtained from force/torque sensing or model-based residuals, often assuming also a nominal environment model. This work addresses the online estimation of the contact force and a possibly time-varying task frame using only soft optical tactile sensing, under the assumption of locally planar contact with a negligible contact moment. The proposed method maps a single image of the deformed elastomer of a soft optical tactile sensor to observable contact variables: indentation depth, two surface-to-sensor tilt angles, and 3D contact force, each with a per-sample uncertainty estimate. The mapping is learned through a self-labeling acquisition procedure, in which a manipulator imposes controlled contacts while an auxiliary Force/Torque sensor is used offline to provide ground-truth labels. The tactile measurement is then fused with robot proprioceptive data in an Extended Kalman Filter, producing a continuously updated estimate of the contact task frame and of the interaction force. Control experiments with a DigiTac sensor mounted on a UR10 manipulator demonstrate closed-loop contact force regulation against a flat rigid board in linear and angular motion by a human operator, with touch as the only exteroceptive feedback.

Video-to-Model: Automatic Modeling of Deformable Linear Objects

视频到模型:可变形线性物体的自动建模
Sharma, Akshun, Forghani, Kimia, Diaz-Mercado, Yancy
Abstract
This paper presents a video-to-model framework for automatically modeling the motion of a deformable suture thread from an input video. We utilize a recently developed CBF--CLF--QP numerical model that simplifies the characterization of deformable string motion through the selection of a small number of parameters. A perception module first localizes and tracks the thread in video, producing an ordered sequence of thread nodes. The observed thread motion is then processed by a spatio-temporal CNN network that estimates the effective parameters of a structured CBF--CLF--QP model. These parameters are used to simulate the thread under a user-defined needle velocity input. Experiments using unseen thread configurations and motion demonstrate that the framework can reliably reconstruct the thread behavior from video, automatically configure the structured model, and reproduce the expected thread motion with low tracking error. The proposed approach reduces the need for manual parameter tuning and provides a step toward automatic video-based modeling of deformable linear objects.

Distributed Motion Planning for Multi-Robot Systems under Topological Constraints

基于拓扑约束的多机器人系统分布式运动规划
Battocletti, Gianpietro, Boskos, Dimitris, Dimarogonas, Dimos V., De Schutter, Bart
Abstract
Efficient and distributed coordination of mobile robots is one of the main challenges in multi-robot systems. Topological constraints, often expressed as topological braids, are a popular tool to encode complex coordination patterns between multiple mobile robots, as they offer a compact and abstract representation of the desired qualitative relation between the space-time trajectories of the robots. However, execution of joint motion plans encoded as braid-based topological constraints via distributed controllers is challenging, with existing approaches, generally based on the execution of one braid generator at a time, producing slow and suboptimal trajectories. We propose a distributed controller based on Model Predictive Control (MPC) to efficiently execute braid-based topological specifications. Rather than directly tracking the braid specification, we propose to use winding numbers, which are topological invariants for braids, as a proxy. This has the twofold benefit of converting braids into a continuous function, which can be easily tracked by an MPC controller through an appropriate term in the cost function, and of decoupling the global braid specification into a set of pairwise specifications, which can be tracked distributedly through the solution of only local MPC problems. To maintain global coordination, we propose a consensus-based progress estimation approach, which allows the robots to synchronize their motion toward the desired specification. We validate the proposed approach in simulation and in real-world experiments, where we demonstrate the effectiveness of the proposed approach and the improvement over existing approaches in terms of execution speed and control effort.

移动机器人高效且分布式的协调是多机器人系统面临的主要挑战之一。拓扑约束,通常以拓扑编织的形式表达,是编码多个移动机器人之间复杂协调模式的热门工具,因为它们提供了所需的机器人时空轨迹之间定性关系的紧凑和抽象表示。然而,通过分布式控制器执行编码为基于编织的拓扑约束的联合运动计划是具有挑战性的,现有方法通常基于一次执行一个编织生成器,导致生成缓慢且次优的轨迹。我们提出了一种基于模型预测控制(Model Predictive Control, MPC)的分布式控制器,以高效执行基于编织的拓扑规范。我们建议使用缠绕数作为代理,而不是直接跟踪编织规范,缠绕数是编织的拓扑不变量。这具有双重好处:将编织转换为连续函数,MPC控制器可以通过成本函数中的适当项轻松跟踪;并将全局编织规范解耦为一组成对规范,可以通过仅解决局部MPC问题进行分布式跟踪。为了保持全局协调,我们提出了一种基于共识的进度估计方法,使机器人能够同步其运动以朝向所需规范。我们在仿真和实际实验中验证了所提方法,展示了该方法的有效性以及在执行速度和控制努力方面相较于现有方法的改进。

RealtimeWAM: How Fast Can I Run My World Action Model?

实时世界动作模型(RealtimeWAM):我能多快运行我的世界动作模型?
Liu, Huanan, Li, Ye, Ji, Kangye, Chen, Xiaoyu, Cui, Hanyun, Shen, Yutian, Meng, Yuan, Wu, Chenglei, Jiang, Jingyan, Li, Bo, Wang, Zhi
Abstract
World Action Models (WAMs) combine visual dynamics modeling with action generation, but their high inference latency limits responsive robot control. Recent efforts accelerate inference by removing explicit future-video generation at test time, as in FastWAM, an approach that requires a specially tailored architectural design. More general caching strategies exploit feature redundancy, but redundancy alone does not capture the changing computational demands of closed-loop control. To address these challenges, we present RealtimeWAM, a general, training-free framework that coordinates parallel execution with adaptive computation for low-latency inference across diverse WAM architectures. We exploit layerwise dependencies to overlap observation processing with prediction. However, concurrent branches still compete for GPU resources, limiting the benefit of parallel execution. We therefore adapt computation throughout the pipeline through selective reuse, caching observation features in visually stable regions and reusing Transformer residuals while reserving additional refinement for small predicted adjustments. We evaluate RealtimeWAM on FastWAM and OpenWAM across RoboTwin, LIBERO, and LIBERO-Plus. On an RTX 4090, measured mean inference latencies are 24.09 and 63.09 ms, corresponding to average speedups of 8.90$\times$ and 10.67$\times$. Average success rates are 82.75% and 87.41%, respectively, within 0.02 and 0.53 percentage points of native inference. Across five real-world tasks, RealtimeWAM improves average success rates over native inference by 17.2 and 37.2 percentage points on FastWAM and OpenWAM, respectively.

Lifelong small-object navigation in changing object layouts: a benchmark and method

在变化物体布局中的终身小物体导航:基准与方法
Huang, Jiagan, Zhou, Zikun, Ni, Zijian, Wang, Hongpeng, Lu, Guangming, Yu, Jun, Pei, Wenjie
Abstract
Household robots need to continually navigate to different objects in the same environment, many of which are small and portable, such as tools and toys. Their small visual footprint and frequent occlusion make reliable observation difficult, and they may be moved by people without the robot observing the changes. We formulate this challenging task as Lifelong Small-object Navigation in Changing Object Layouts (LiSoNav-COL). Agents must seek suitable viewpoints for reliable observation, accumulate and reuse scene knowledge to efficiently locate subsequent targets, and update outdated memory after object relocation. To eliminate the need for prior scene scanning, we also require agents to start navigation with empty scene memory. Although practical, this task still lacks benchmarks designed around its defining assumptions. To bridge this gap, we introduce LiSoNav-Eval, a dedicated benchmark spanning 28 indoor scenes with 45 small-object categories. Its lifelong navigation sequences include both unchanged and relocated targets to evaluate memory reuse and adaptation to object relocation. To address this challenging task, we propose a navigation method based on multi-view Inspection with Viewpoint-Anchored Memory, dubbed IVAM-Nav. IVAM-Nav actively observes supporting surfaces from complementary viewpoints for reliable small-object perception and anchors the resulting memory to their observation viewpoints, supporting relational memory reuse and revalidation under similar viewing conditions. Extensive experiments on LiSoNav-Eval demonstrate favorable performance of IVAM-Nav against representative methods. Benchmark analyses also show that smaller objects, larger environments, and longer relocation distances pose greater challenges. The dataset and code are available here.

家庭机器人需要在同一环境中不断导航到不同的物体,其中许多物体较小且便于携带,如工具和玩具。它们小的视觉占据面积和频繁的遮挡使得可靠观察变得困难,并且可能在机器人未观察到变化的情况下被人移动。我们将这一具有挑战性的任务定义为在变化物体布局中的终身小物体导航(Lifelong Small-object Navigation in Changing Object Layouts,LiSoNav-COL)。代理必须寻找合适的视点以进行可靠观察,积累并重用场景知识以有效定位后续目标,并在物体重新定位后更新过时的记忆。为了消除对先前场景扫描的需求,我们还要求代理在导航时从空的场景记忆开始。尽管这一任务具有实际意义,但仍缺乏围绕其定义假设设计的基准。为填补这一空白,我们引入了LiSoNav-Eval,这是一个专门的基准,涵盖28个室内场景和45个小物体类别。其终身导航序列包括未变化和重新定位的目标,以评估记忆重用和适应物体重新定位的能力。为了解决这一挑战性任务,我们提出了一种基于多视角检查与视点锚定记忆的导航方法,称为IVAM-Nav。IVAM-Nav主动从互补视点观察支撑表面,以实现可靠的小物体感知,并将生成的记忆锚定到其观察视点,支持在相似观察条件下的关系记忆重用和重新验证。在LiSoNav-Eval上的大量实验表明,IVAM-Nav在与代表性方法的比较中表现良好。基准分析还显示,较小的物体、更大的环境和更长的重新定位距离带来了更大的挑战。数据集和代码可在此处获取。

Do Vision-Language-Action Models Understand Instructions? A Mechanistic Interpretability Study on Language Grounding

视觉-语言-行动模型是否理解指令?关于语言基础的机制可解释性研究
Wulff, Theodor, Cangelosi, Angelo
Abstract
Vision-Language-Action models are designed to generalise across environments and task descriptions, raising the question of whether their action generation actually depends on the language instruction, or whether they largely rely on visual cues and superficial correlations. Robustness to variance in the visual and linguistic observation space is critical for real-world deployment, yet VLAs lack explicit grounding modules and instead rely on the intrinsic language grounding capabilities of their Vision-Language model backbones. For this reason, we conduct a controlled mechanistic interpretability study on the language grounding capabilities of two state-of-the-art Vision-Language-Action models, $\pi_{0.5}$ and GR00T N1.7, by applying activation and attribution patching to the residual stream of the action generation modules. We systematically corrupt the task instruction of input samples of the LIBERO benchmark following five strategies: synonym replacement, semantic scaling, directional corruption, random object substitution, and empty string. Our experiments find that both models are comparatively insensitive to abstract rephrasing and to referencing non-existent objects, but react strongly to empty task descriptions and, especially, to directional language. During action generation, this sensitivity is concentrated in different loci for each model: mainly in the early, periodic cross-attention layers for GR00T N1.7, versus distributed across the earliest and selected later layers for $\pi_{0.5}$. For GR00T N1.7, directional perturbations drive some of the largest causal effects while leaving the internal representational geometry comparatively unchanged, a dissociation we do not observe clearly for $\pi_{0.5}$. Finally, the reliability of attribution patching is model-dependent: it closely tracks activation patching for GR00T N1.7 but not for $\pi_{0.5}$.

视觉-语言-行动(VLA)模型旨在跨环境和任务描述进行泛化,这引发了一个问题:它们的行动生成是否真正依赖于语言指令,还是主要依赖于视觉线索和表面相关性。对于现实世界的部署,视觉和语言观察空间的变异性鲁棒性至关重要,然而VLA缺乏明确的基础模块,而是依赖于其视觉-语言模型骨干的内在语言基础能力。因此,我们对两个最先进的视觉-语言-行动模型$ ext{π}_{0.5}$和GR00T N1.7的语言基础能力进行了控制的机制可解释性研究,通过对行动生成模块的残差流应用激活和归因补丁。我们系统地按照五种策略腐蚀LIBERO基准的输入样本的任务指令:同义词替换、语义缩放、方向性腐蚀、随机对象替换和空字符串。我们的实验发现,这两个模型对抽象的重述和引用不存在的对象相对不敏感,但对空任务描述,尤其是对方向性语言反应强烈。在行动生成过程中,这种敏感性在每个模型中集中在不同的区域:对于GR00T N1.7,主要集中在早期的周期性交叉注意层,而对于$ ext{π}_{0.5}$则分布在最早和选定的后续层。对于GR00T N1.7,方向性扰动驱动了一些最大的因果效应,同时内部表示几何相对不变,这种解离在$ ext{π}_{0.5}$中并未明显观察到。最后,归因补丁的可靠性依赖于模型:对于GR00T N1.7,它与激活补丁密切相关,但对于$ ext{π}_{0.5}$则不然。

Design of a Fully Actuated 4-DOF Robotic Finger With Joint-Specific Hybrid Remote Actuation

具有关节特定混合远程驱动的全驱动4自由度机器人手指设计
Kang, Hyojae, Jung, Hyun-mok, Lee, Joonho, Park, Dongil, Do, Hyunmin, Park, Jongwoo, Ahn, Jeongdo
Abstract
This paper presents a fully actuated 4-DOF robotic finger using a joint-specific hybrid remote-actuation architecture. The metacarpophalangeal (MCP) joint is driven by two coordinated rigid-link transmission sets, whereas the proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints are independently actuated by closed-loop wire transmissions incorporating circular rolling-contact joints (RCJs). A larger transmission radius is used at the PIP joint than at the DIP joint. The RCJ wire geometry maintains the total wire-loop length during joint rotation, and the DIP wire routing is designed so that PIP motion does not affect its differential actuation for a fixed MCP configuration. The distal wire transmission, MCP linkage, and fingertip kinematics are analytically modeled. In experiments, the transmission behavior was quantitatively evaluated from the ball-screw displacements measured using ArUco-marker tracking. MCP actuation produced measurable displacements of the PIP and DIP transmission units, whereas isolated PIP and DIP actuation with the MCP fixed supported the intended mechanical decoupling between the distal transmissions. The mean peak fingertip forces under isolated MCP, PIP, and DIP actuation were 21.28 N, 9.22 N, and 5.75 N, respectively. The resulting finger postures were also examined using objects of different geometries and sizes.

Abstract
Behavior Foundation Models (BFMs) are emerging as a paradigm for translating human intentions into executable humanoid behaviors. As these models evolve beyond behavior generation toward general-purpose behavioral systems, a fundamental question arises: can they be reliably steered according to user intentions? In this paper, we introduce the concept of behavioral steerability, defined as the ability of BFMs to faithfully generate behaviors that satisfy user-specified intentions. To study this capability, we present RoboSteer, the first benchmark for behavioral steerability in BFMs. RoboSteer organizes behavioral steerability into a three-level hierarchy-Conditional Steering, Constraint Steering, and Compositional Steering-and establishes a unified evaluation framework supported by a large-scale multimodal motion corpus. Using RoboSteer, we conduct the first large-scale empirical study of behavioral steerability across 9 existing BFMs. We view behavioral steerability as more than a capability for controlling motion: it concerns how embodied systems translate human intentions into purposeful actions. We hope RoboSteer will advance research on intention realization as a foundation for general-purpose embodied intelligence.

Making Task Abstractions Executable: Control-Aware Layout Repair for a Fixed Controller

Kim, Chiyoung, Back, Seungyeon, Shim, Sumin, Heo, Doyoung, Singh, Rita
Abstract
A task abstraction can specify the intended events while its spatial layout prevents a fixed agent and controller from completing them. Starting from a supplied structured task record, we compile whole-task tracking, clearance, and actuation requirements into auditable affine layout constraints. We repair only declared continuous coordinates, preserving event order, timing, topology, and the controller. A most-violated-row update admits conditional finite-certification and net-displacement bounds; a same-compiler quadratic projection separates the representation from the optimizer. On three researcher-authored task abstractions, both backends certify all three layouts and complete all 300 fresh paired rollouts per backend. A risk-target sweep also exposes fixed event tests that the chosen certificate cannot satisfy through layout edits alone.

Temporal Visuo-Tactile Learning for Dexterous Grasp Stability

用于灵巧抓握稳定性的时间视觉-触觉学习
Nakahara, Ken, Buvailik, Aleksei, Kotov, Prokhor, Calandra, Roberto
Abstract
Humans can grasp everyday objects with almost perfect success rates using fingertip tactile feedback, yet much of the robotic grasping literature emphasizes vision-based grasp selection with parallel grippers. In this work, we systematically investigate how high-resolution, dynamic tactile sensing contributes to grasp stability prediction and model-guided grasping in dexterous robotic hands. To this end, we collected a dataset of 10,000 grasp trials across 200 objects using a multi-fingered robotic hand equipped with four Digit 360 tactile sensors, recording external vision, proprioception, and tactile streams throughout each grasp. With this dataset, we trained end-to-end temporal multimodal models to predict post-lift stability from pre-lift grasp observations and compared sensing modalities and encoding backbones. Experimental results and controlled input ablations show that incorporating touch, and particularly high-resolution, dynamic touch, improves grasp stability prediction. Finally, we deployed the learned predictor as an online stability gate on the real robot, where visuo-tactile model-guided regrasping improved the success rate among executed lifts by 10.5 percentage points over a non-tactile gate. These results show how rich fingertip sensing and expressive temporal models that capture the dynamics of touch can support learned grasping with multi-fingered hands without explicit contact or force modeling, providing a scalable data-driven path from tactile experience toward stable dexterous manipulation. The dataset is publicly available at https://lasr-lab.github.io/dexterous-grasp-stability/.

Energy-Efficient Gait Adaptation via Hierarchical Reinforcement Learning for Quadrupedal Locomotion Across Diverse Terrains

基于分层强化学习的能效步态适应:四足机器人在多样地形中的运动
Issa, Ammar, Singh, Anubhav, Tsaritsin, Anton, Kolyubin, Sergey
Abstract
While energy efficiency is a critical objective for legged-robot locomotion control, achieving low energy consumption while maintaining robust performance across different velocity ranges and terrain conditions remains a key challenge. This is particularly true for end-to-end RL policies, where gait generation, motion execution, and energy optimization are tightly coupled, leading to high sensitivity to reward design. In this work, we propose a hierarchical reinforcement learning (HRL) framework that separates a high-frequency policy for stable and robust joint-level motion execution from low-frequency gait adaptation that explicitly minimizes the cost of transport (CoT). The three-stage Isaac-based training procedure enables zero-shot sim-to-real transfer with improved tracking accuracy, robustness, and energy efficiency. The learned hierarchy exhibits automatic speed-dependent gait adaptation, transitioning from pacing at low speeds to trotting at higher speeds. We validate the proposed approach in simulation against representative single-policy and hierarchical locomotion baselines, demonstrating reduced CoT over a broad range of commanded velocities, while maintaining robust locomotion across flat, uneven rough, and inclined terrains. We further demonstrate its practical feasibility through zero-shot deployment on a physical Unitree AlienGo quadruped.

Robotic minimally invasive surgery has revolutionized surgical practice. However, as the surgeons are mechanically separated from the surgical tools, loss of tactile feedback occurs.

The sensor features a miniaturized design using Hall effect sensors and magnets embedded in a deformable elastomer contact layer. Sensor calibration is achieved with a 6 degree of freedom (DoF) parallel robot. Each taxel can detect applied normal and shear forces with average RMSE of 2.133 kPa. The calibrated sensor was validated on phantom and ex vivo porcine tissue, demonstrating tactile sensing during retraction as well as slip. This work introduces a small-scale Hall effect based tactile sensor, enabling sensing for force-sensitive robotic surgical applications.

MultiFly: A Real-World Multimodal Aerial Dataset with Annotation-Efficient Label Transfer and Cross-Modal Semantic Consistency

MultiFly:一个具有高效标注转移和跨模态语义一致性的真实世界多模态空中数据集

Abstract
We introduce MultiFly, a real-world, low-altitude UAV dataset for semantic perception across RGB, thermal, LiDAR, and radar modalities. MultiFly provides 17,272 synchronized samples from four suburban scenes with frame-wise annotations for 15 semantic classes, together with calibration and GNSS-RTK/IMU measurements. To avoid costly and inconsistent modality-specific annotation, we propagate labels from only 115 manually annotated RGB images through shared geometric representations to all four modalities. This approach generates semantic labels for 17,157 additional RGB images, 17,272 thermal images, 840M LiDAR points, and 3.4M radar points. Transferred annotations achieve 89.93% average agreement with held-out manual annotations, and 90.94% average semantic consistency across all six modality pairs. We further establish semantic segmentation benchmarks for all four modalities, revealing distinct architectural behavior for dense LiDAR and sparse radar data. Taken together, MultiFly provides a scalable foundation for multimodal aerial perception and, to the best of our knowledge, the first public real-world low-altitude aerial benchmark that combines consistent frame-wise semantic annotations for RGB, thermal, LiDAR, and radar.

Semantic-Aware Predictive Mapping for Exploration and Navigation

语义感知的预测映射用于探索与导航
Ong, Kenneth J. K., Teo, William W. J.
Abstract
Predictive mapping can support robotic exploration and navigation by estimating unseen geometric layouts from partial occupancy observations. However, occupancy-only representations may fail to distinguish semantically different structures with similar geometry. This is particularly relevant for indoor doors, which may appear as occupied cells like walls but indicate possible connected rooms or corridors beyond the observed region. This work investigates whether semantic door cues improve predictive geometric occupancy mapping around such ambiguous regions. We modify a subset of the CogniPlan dataset by inserting door-induced ambiguities into partial occupancy maps while keeping the ground-truth layouts unchanged. We compare a geometry-only control model with a semantic-cued model trained on the same modified dataset, where the semantic-cued model receives an additional door channel. Evaluation uses L1 error, F1 score, and Intersection over Union (IoU) over both the full map and a 10-pixel door-region mask. Full-map performance remains broadly similar between models, but localized door-region results show a clear qualitative improvement: L1 decreases from 0.004342 to 0.000025, while F1 and IoU improve from 0.031311 and 0.015905 to 1.000000 and 1.000000, respectively. These results suggest that semantic cues can improve predictive occupancy completion in regions where geometric observations alone are ambiguous.

OpenViTac: Learning and Benchmarking Visuo-Tactile Policies in a Unified Sim-and-Real Framework

OpenViTac:在统一的仿真与现实框架中学习和基准测试视觉-触觉策略

Abstract
Tactile feedback provides embodied agents with physical information beyond visual observations, enabling more reliable interaction with the real world. However, despite the rapid progress of vision-tactile-language-action (VTLA) policies, there remains a lack of unified benchmarks for evaluating tactile-enabled robot manipulation across simulation and the real world. To address this gap, we introduce OpenViTac, a visuo-tactile manipulation benchmark for evaluating robot policies across simulation and the real world. OpenViTac organizes contact-rich manipulation into four tactile-relevant capability dimensions and provides paired simulation-real-world settings for consistent evaluation of VLA, WAM, and VTLA policies. Building upon this benchmark, we investigate how different tactile representations and integration strategies affect the performance of pretrained VLA models. Correspondingly, we introduce OpenVTLA, a tactile augmentation framework that combines the best-performing representation and integration strategy. Furthermore, we leverage the paired benchmark setting to study sim-real co-training and analyze factors affecting cross-domain policy learning. Together, OpenViTac provides a unified platform for evaluating and advancing visuo-tactile robot manipulation.

NeRFifyMesh: Optimizing Neural Radiance Fields from Textured Meshes for Robotics Scene Building

NeRFifyMesh:从纹理网格优化神经辐射场以构建机器人场景
Nimal, Nillan, Asadi, Mahboubeh, Saeedi, Sajad
Abstract
In robotics, scene representation plays a pivotal role in understanding and interacting with the environment. The advent of Neural Radiance Fields (NeRF) and its variants, as a novel representation, has opened a new frontier of research. In applications such as semantic mapping and simulation, roboticists aim to build scenes using multiple NeRF models, each representing an object. While extensive datasets of 3D mesh models already exist, there is an urgent need to develop tools to convert these assets to NeRF models for rapid algorithm development and testing. This paper presents a new pipeline for converting existing mesh models to NeRF representations by artificially generating a ground truth point-based radiance field through sampling mesh geometry and texture. This approach alleviates the need for camera-based sampling or rendering multi-view images of the original mesh to train the NeRF model. Extensive benchmarking demonstrates that our method yields comparable rendering quality to the baselines. Additionally, the application of this representation is shown by constructing unified NeRF scenes and performing collision simulations with extracted geometry.

RoboQuest: Generalist Physical Agents that Search, Inspect and Test

RoboQuest:通用物理智能体的搜索、检查与测试
Renhang, Liu, Majumder, Navonil, Pala, Tej Deep, Poria, Soujanya
Abstract
Recent advances in multimodal foundation models have made them capable generalist physical agents for a range of manipulation tasks. However, successful operation in an unfamiliar environment may require an agent to seek task-relevant information through interaction when it is absent from the observations: it may need to determine where a relevant object is, inspect an unobserved property, or discover the effect of an unfamiliar tool. We thus introduce RoboQuest, a benchmark for goal-directed embodied exploration, where agents must actively acquire task-relevant information through physical interaction, use the resulting evidence to adapt subsequent actions, and autonomously decide when to commit to task completion. RoboQuest comprises ten mobile manipulation tasks centered on three forms of uncertainty: search, manipulation-based inspection, and interactive testing. We evaluate five frontier multimodal agents through a common visuomotor interface, as well as a $\pi_{0.5}$ policy fine-tuned on the full-episode demonstrations we release. The best agent succeeds in only 23\% of the episodes, and the fine-tuned policy almost never succeeds. Isolated tests of the execution skills the tasks are built from, with the hidden information supplied, show that the agents can carry out most of the required actions, and our failure analysis attributes only a minority of the failures to execution. Our failure analysis further finds that the agents often stop exploring too early as they make decisions before observing the required evidence for task completion. We also find that agents rarely prevent or repair the disturbances caused by their exploration. Moreover, learning by trial and error remains difficult for most models.

近期多模态基础模型的进展使其能够作为通用物理智能体执行一系列操作任务。然而,在陌生环境中成功操作可能需要智能体通过交互来获取缺失的与任务相关的信息:它可能需要确定相关物体的位置、检查未观察到的属性,或发现不熟悉工具的效果。因此,我们引入了RoboQuest,一个针对目标导向的具身探索的基准,其中智能体必须通过物理交互主动获取与任务相关的信息,利用所获得的证据调整后续行动,并自主决定何时完成任务。RoboQuest包含十个以移动操控为中心的任务,围绕三种不确定性形式展开:搜索、基于操控的检查和交互测试。我们通过一个共同的视觉运动接口评估五个前沿多模态智能体,以及一个在我们发布的完整回合演示上微调的$ ext{π}_{0.5}$策略。表现最好的智能体仅在23%的回合中成功,而微调的策略几乎从未成功。对构建任务的执行技能进行的孤立测试(提供隐藏信息)显示,智能体能够执行大多数所需的动作,而我们的失败分析仅将少数失败归因于执行问题。我们的失败分析进一步发现,智能体常常过早停止探索,因为它们在观察到完成任务所需的证据之前就做出了决策。我们还发现,智能体很少防止或修复其探索所造成的干扰。此外,对于大多数模型而言,通过试错学习仍然困难。

Abstract
General-purpose agents increasingly write code, use tools, and complete complex digital tasks, raising the question of how far these capabilities carry into the physical world. To investigate this, we introduce RobotWorld, a challenging simulation testbed for robot use: turning instructions and observations into physical task execution through robot interfaces. Its 84 tasks span manipulation, mobile manipulation, locomotion, driving, and aerial control, with explicit interaction budgets and executable success checks. By analysing task outcomes alongside execution traces, we identify both the capabilities that transfer and the gaps that prevent reliable completion. Furthermore, we find that current agents can construct sophisticated perception and control workflows, including image segmentation, camera calibration, spatial estimation, and dynamics-based computation. These capabilities, however, do not consistently compose into successful behaviour: agents lose task-relevant object states despite reaching commanded poses, fail to correct ineffective actions, recover too late, or mistake unfinished tasks for completion. This uneven transfer also differs across models: Astra succeeds more often on spatial and constrained-contact goals, whereas Opus 5.5 succeeds more often on continuous-balance and timed-interaction goals. By linking these outcomes to execution behaviour, RobotWorld provides both a rigorous proving ground and an empirical account of the remaining capability gaps, thereby establishing concrete targets for training and designing more reliable physical-world agents.

AirGroundVLN: A Large-Scale Benchmark for Goal-Oriented Air-Ground Collaborative Vision-and-Language Navigation

AirGroundVLN:面向目标的空地协作视觉与语言导航的大规模基准
Zeng, Zhenxuan, Wu, Qingle, Suo, Wei, Wu, Maojia, Zhang, Bairong, Yu, Hangzheng, Wang, Peng
Abstract
Goal-oriented Vision-and-Language Navigation (VLN) requires agents to locate and reach targets described in natural language without prescribed routes. Air--ground collaboration is valuable for tasks requiring both wide-area search and fine-grained localization. However, systematic study of goal-oriented air--ground collaborative VLN remains limited by the lack of large-scale, diverse benchmarks and two core challenges: 1) substantial differences between aerial and ground views, together with useful observations becoming unavailable as navigation proceeds, make it difficult to maintain spatially consistent context across platforms and over time; and 2) asymmetric spatial observability makes ground perception locally detailed but spatially limited and aerial perception broad but locally coarse, limiting the reliability of single-platform planning. To address these limitations, we introduce AirGroundVLN, a benchmark containing 10,281 navigation episodes and 955 target instances across 19 Unreal Engine environments, with seen/unseen splits and an aerial-visibility protocol for systematic evaluation. Alongside the benchmark, we propose AG-CoNAV, a trainable reference framework comprising two key components: Spatiotemporally Anchored Collaborative Memory (SACM) and Aerial-Guided Regional-to-Local Planning (AGRLP). SACM maintains and retrieves spatially consistent historical context across aerial and ground observations. Meanwhile, AGRLP combines regional aerial guidance with fine-grained ground navigation. Extensive experiments demonstrate the effectiveness of AG-CoNAV and establish AirGroundVLN as a comprehensive benchmark for future exploration.

RFPO: Rectified Flow Policy Optimization for Embodied Control

RFPO:用于具身控制的修正流策略优化
Huang, Ting, Pan, Lisiyu, Wang, Haoyu, Zhang, Zeyu, Qian, Siyuan, Li, Yanjun, Guo, Yandong, Shi, Boxin, Tang, Hao
Abstract
Flow-based policies provide an expressive framework for continuous robot control, but their iterative ODE integration incurs substantial inference cost. Naively reducing the integration budget can severely degrade control, since policies optimized under full-step execution are not explicitly constrained to remain reliable under coarse numerical integration. We refer to this mismatch as the few-step discretization gap. To address this problem, we introduce RFPO, a flow-policy optimization framework for reliable few-step execution. Reward-aware online Reflow rectifies student-induced transport paths during on-policy learning, making the resulting policy more robust to coarse integration. A frozen Gaussian PPO controller supplies complementary action-space supervision at full and intermediate integration budgets, while the deployed policy remains a single flow student executed with one Euler step. Across Unitree Go2, Boston Dynamics Spot, Unitree H1, and Unitree G1, RFPO consistently preserves full-step control performance under one-step execution, with one-step returns remaining within 2.4% of their corresponding 64-step values across both zero and random initialization. On Unitree Go2, one-step execution retains 98.5% of the 64-step reward while reducing onboard mean inference latency from 4.39 ms to 0.08 ms, yielding a 54.9x speedup. Real-robot experiments further validate stable one-step locomotion. Code: https://github.com/AIGeeksGroup/RFPO. Website: https://aigeeksgroup.github.io/RFPO.

基于流的策略为连续机器人控制提供了一个表达性框架,但其迭代的常微分方程(ODE)积分会产生相当大的推理成本。简单地减少积分预算可能会严重降低控制性能,因为在全步执行下优化的策略并未明确约束在粗略数值积分下保持可靠性。我们将这种不匹配称为少步离散化差距。为了解决这个问题,我们引入了RFPO,一种用于可靠少步执行的流策略优化框架。奖励感知的在线重流(Reflow)在策略学习过程中修正学生引导的传输路径,使得生成的策略对粗略积分更加稳健。一个冻结的高斯PPO控制器在全积分和中间积分预算下提供补充的动作空间监督,而部署的策略仍然是一个通过一个欧拉步执行的单一流学生。在Unitree Go2、波士顿动力Spot、Unitree H1和Unitree G1上,RFPO在单步执行下始终保持全步控制性能,单步回报在零初始化和随机初始化下均保持在其对应的64步值的2.4%以内。在Unitree Go2上,单步执行保留了64步奖励的98.5%,同时将板载平均推理延迟从4.39毫秒减少到0.08毫秒,实现了54.9倍的加速。真实机器人实验进一步验证了稳定的单步运动。代码:https://github.com/AIGeeksGroup/RFPO。网站:https://aigeeksgroup.github.io/RFPO。

FoldBack: Self-Correcting Masked Generative Policy for Long-Horizon Garment Folding

FoldBack:用于长时间服装折叠的自我修正掩蔽生成策略
Zhuang, Lipeng, Fan, Shiyu, Ru, Yingdong, He, Zhuo, Audonnet, Florent P., Henderson, Paul, Camarasa, Gerardo Aragon
Abstract
We present FoldBack, a self-correcting masked generative policy for long-horizon garment folding. Existing long-trajectory policies may continue after a missed or slipped grasp even when the garment has not reached the intended configuration. We structure FoldBack's recovery mechanisms around three inference-time decisions: when to refine and verify, how to roll back, and where and how to retry. FoldBack aligns refinement and grasp verification with pick-and-place events, returns the robot to a retryable pre-grasp configuration while preserving successful grasps, and selectively regenerates the failed segment and selected future actions while avoiding previous failed grasp locations. To our knowledge, FoldBack is the first editable full-trajectory policy to unify these decisions, enabling failed interactions to be detected, undone, and repaired before execution continues, without recovery demonstrations or base-policy retraining. Across 33 real garments from six categories, FoldBack achieves 75.2% final folding success and 0.837 final-mask IoU, versus 45.7% and 0.689 for the strongest prior baseline.

LLA-MPPI: Rapidly Adaptive Whole-body Control of Legged Robots with GPU-Accelerated Parallel Simulations

LLA-MPPI:基于GPU加速并行仿真的快速自适应全身控制的腿式机器人
Jung, Sebin, AL-Sunni, Maitham F., Alvarez-Padilla, Juan, Manchester, Zachary, Liu, Changliu, Dolan, John M.
Abstract
Real-time whole-body controllers for legged robots typically plan through a fixed nominal model and degrade when the deployed dynamics change. Adaptive methods typically require a model structure that contact dynamics do not provide, or they need offline training for each anticipated condition. We present Look-back and Look-ahead Adaptive Model Predictive Path Integral control (LLA-MPPI). The method converts whole-body adaptation into selection over a bank of GPU-batched contact simulators with different physical or structural parameters. Windowed prediction errors select the simulator that best explains recent motion. A whole-body MPPI planner optimizes controls through the selected model. The framework requires no offline training, and its selected hypotheses are physically interpretable. Across four simulated tasks, it achieves 97.5% success while the strongest baseline reaches 74% and an oracle with the true model reaches 98.5%. Hardware validation on a Unitree Go2 shows the robot walking under a payload added mid-run, walking after one leg is disabled, and pushing a box to its goal while increasing its mass on the fly.

CMP-IRRT*: A Perception-Assisted Height-Adaptive Planner for Quadruped Robots

CMP-IRRT*: 一种感知辅助的高度自适应四足机器人规划器
Zhao, Mingfan, Mao, Wendong, Wang, Zhongfeng
Abstract
Quadruped robots can traverse low obstacles, but many 2D planning pipelines still model obstacles as binary occupied regions and rely on sampling-based search that can be inefficient under a limited budget. We propose a perception-assisted height-adaptive planning framework based on CMP-IRRT*, a Channel Mamba PointNet-guided Informed RRT* planner. Given a calibrated top-view RGB observation, the perception module estimates obstacle regions and converts depth predictions into a ground-relative height map. The planner then performs height-conditioned collision checking, treating high obstacles as blocked while allowing low obstacles to be traversed, and uses the CMP guide to bias sampling toward promising regions while retaining standard free-space and informed sampling fallbacks. Experiments on 2D planning benchmarks show that CMP-IRRT* reduces explored nodes and iterations compared with classical and neural-guided baselines, and a controlled ablation supports the contribution of the Mamba-based guide. In constructed traversability-aware scenarios, the proposed planner reduces path length by up to 16.3% when low obstacles are traversable, and a Unitree Go2 demonstration further shows executable bypassing and traversal behaviors. Our code is publicly available at https://github.com/MingfanZhao/height-adaptive-planner.

四足机器人能够跨越低障碍物,但许多二维规划管道仍将障碍物建模为二进制占用区域,并依赖基于采样的搜索,这在预算有限的情况下可能效率低下。我们提出了一种基于CMP-IRRT*的感知辅助高度自适应规划框架,CMP-IRRT*是一种由Channel Mamba PointNet引导的知情RRT*规划器。给定一个经过校准的俯视RGB观测,感知模块估计障碍物区域并将深度预测转换为相对于地面的高度图。然后,规划器执行高度条件的碰撞检测,将高障碍物视为被阻挡,同时允许低障碍物被穿越,并利用CMP引导偏向有前景的区域进行采样,同时保留标准的自由空间和知情采样的回退。对二维规划基准的实验表明,与经典和神经引导的基线相比,CMP-IRRT*减少了探索的节点和迭代次数,控制的消融实验支持了基于Mamba的引导的贡献。在构建的可通行性感知场景中,当低障碍物可穿越时,所提规划器将路径长度减少了最多16.3%,而Unitree Go2的演示进一步展示了可执行的绕行和穿越行为。我们的代码已公开发布在 https://github.com/MingfanZhao/height-adaptive-planner。

Robotic Boomerang Throwing via Model-Based Release Design

基于模型的机器人回旋镖投掷设计
Liu, Yang, Jones, Colin, Billard, Aude
Abstract
Throwing objects that generate aerodynamic lift can greatly extend robot throwing beyond ballistic flight. A returning boomerang is a challenging example because its flight depends strongly on the release velocity, attitude, and spin, while robotic manipulators cannot readily reproduce the rapid motions used in human throwing. We present a model-based framework for robotic boomerang throwing centered on the release state. We identify the boomerang flight dynamics in stages to predict how flight changes across design variations. To systematically design the robot throwing motion, we screen candidate parameters according to how strongly and consistently they control release spin under uncertain contact conditions. These models are then used to design the throwing motion and boomerang for a 6-DoF manipulator with limited joint speeds. To our knowledge, this is the first robotic manipulator to generate a returning boomerang flight. In the demonstrated returning trial, the boomerang is released at 51 rad/s (8.1 rev/s), reaches 2.03 m from the robot base, and returns to touch down 0.31 m from the base. The successful release differs significantly from the measured human throws, showing that a robot need not imitate human throwing motion to achieve a returning flight.

投掷能够产生空气动力学升力的物体可以大大扩展机器人投掷的飞行范围,超越弹道飞行。回旋镖是一个具有挑战性的例子,因为其飞行强烈依赖于释放速度、姿态和旋转,而机器人操控器无法轻易重现人类投掷时的快速动作。我们提出了一个以释放状态为中心的基于模型的机器人回旋镖投掷框架。我们将回旋镖的飞行动力学分阶段识别,以预测设计变体如何影响飞行变化。为了系统地设计机器人投掷动作,我们根据候选参数在不确定接触条件下对释放旋转的控制强度和一致性进行筛选。这些模型随后用于为具有有限关节速度的6自由度(6-DoF)操控器设计投掷动作和回旋镖。据我们所知,这是第一个能够产生回归飞行的机器人操控器。在演示的回归试验中,回旋镖以51 rad/s(8.1 rev/s)的速度释放,距离机器人基座2.03米,并在距离基座0.31米处成功着陆。成功的释放与测量的人类投掷有显著不同,表明机器人不必模仿人类的投掷动作即可实现回归飞行。项目页面可访问 https://robot-boomerang.github.io

Agentic RSR: Real-to-Sim-to-Real through Scene Reconstruction and Execution-Grounded Robot Policies

Agentic RSR:通过场景重建和执行基础的机器人策略实现真实到模拟再到真实
Li, Yihan, Feng, Yating, Sun, Shengjiu, Chen, Jianing, Ren, Hao, Yang, Bowen, Xu, Weisheng, Wu, Qiwei, Cheng, Hui, Xu, Renjing
Abstract
A simulation of a real robot workspace must preserve task-relevant interactions, while policies developed in it must operate on observations available to the real robot. Yet scene reconstruction and policy development are often treated separately. We present Agentic Real-to-Sim-to-Real (Agentic RSR), a framework that links scene reconstruction, policy development, and real-robot execution through the same manipulation task. Given a workspace video, a task description, and a known robot model, an agent recovers metric scale, iteratively refines the scene using visual feedback, and checks task-relevant interactions in MuJoCo. A coding agent then develops an executable policy, progressing from privileged object poses to visual observations and randomized simulation. The policy can interleave multiple observations and actions within one invocation, while the agent uses execution feedback to continue, retry, or revise its approach. A shared task-level interface carries the policy and accumulated experience to the real robot, where fresh observations and safety checks guide execution. Across 18 reconstructed scenes involving two robots, the mean four-view Depth MAE against reference depth estimates is 0.1057 m, the mean Lab $\Delta E_{76}$ is 11.04, and the mean grayscale SSIM is 0.6990. In real-robot experiments, the aggregate task success rate reaches 80% of the simulation task success rate, indicating substantial retention of simulated performance on hardware. Code and reconstructed scene data will be made publicly available.

真实机器人工作空间的模拟必须保留与任务相关的交互,而在其中开发的策略必须基于真实机器人可用的观察。然而,场景重建和策略开发通常被视为两个独立的过程。我们提出了Agentic Real-to-Sim-to-Real(Agentic RSR)框架,该框架通过相同的操作任务将场景重建、策略开发和真实机器人执行联系起来。给定一个工作空间视频、一个任务描述和一个已知的机器人模型,智能体恢复度量尺度,利用视觉反馈迭代地细化场景,并在MuJoCo中检查与任务相关的交互。然后,一个编码智能体开发可执行策略,从特权对象姿态逐步过渡到视觉观察和随机化模拟。该策略可以在一次调用中交替多个观察和动作,而智能体使用执行反馈来继续、重试或修正其方法。一个共享的任务级接口将策略和积累的经验传递给真实机器人,在那里新的观察和安全检查指导执行。在涉及两个机器人的18个重建场景中,与参考深度估计相比,平均四视图深度均方误差(Depth MAE)为0.1057米,平均Lab $ riangle E_{76}$为11.04,平均灰度结构相似性(SSIM)为0.6990。在真实机器人实验中,整体任务成功率达到了模拟任务成功率的80%,表明在硬件上显著保留了模拟性能。代码和重建场景数据将公开发布。

Abstract
Despite recent advances in humanoid locomotion, controllers optimized for command tracking and robustness tend to produce mechanical gaits, whereas controllers tied to human motion data often fail to generalize to commands outside the data distribution. This work introduces a learning framework that balances these competing objectives to synthesize real-time steerable, robust, and biomimetic locomotion policies from human data. Using an in-house curated locomotion dataset covering diverse speeds and directions, we first learn a natural locomotion prior policy through a teacher-student distillation process. Specifically, we train a full-body reference-conditioned policy with Reinforcement Learning (RL), then distill it into a lightweight prior policy conditioned solely on proprioception and a planar torso-velocity steering command. Next, we fine-tune the prior policy with multi-task RL to expand command coverage and robustness beyond the data distribution, pairing a goal-conditioned task that tracks arbitrary commands with a reference-guided task that tracks the human data as an explicit style regularizer. We validate our framework on three humanoid robots: the Boston Dynamics Atlas R1, Atlas D1, and Unitree G1. Experimental results demonstrate robust performance across real-world scenarios, including direct user-controlled locomotion in indoor and outdoor environments, and integration as the locomotion layer within hierarchical control stacks. Benchmarks against Tabula Rasa RL policies trained without human data and ablation studies confirm that our framework yields a lightweight, deployable policy that reconstructs coordinated whole-body behavior from a steering command, retaining the human gait characteristics while remaining robust and fully steerable.

尽管近年来在类人运动方面取得了进展,但针对指令跟踪和鲁棒性优化的控制器往往会产生机械化的步态,而与人类运动数据相关的控制器则常常无法推广到数据分布之外的指令。本文提出了一种学习框架,平衡这些相互竞争的目标,从人类数据中合成实时可调、鲁棒且仿生的运动策略。我们使用一个涵盖多种速度和方向的内部策划运动数据集,首先通过教师-学生蒸馏过程学习自然运动的先验策略。具体而言,我们使用强化学习(Reinforcement Learning, RL)训练一个全身参考条件的策略,然后将其蒸馏为一个仅基于本体感觉和一个平面躯干速度转向指令的轻量级先验策略。接下来,我们通过多任务强化学习对先验策略进行微调,以扩展指令覆盖范围和鲁棒性,超出数据分布,结合一个跟踪任意指令的目标条件任务与一个跟踪人类数据的参考引导任务作为显式风格正则化器。我们在三种类人机器人上验证了我们的框架:波士顿动力的Atlas R1、Atlas D1和Unitree G1。实验结果表明,在真实场景中表现出良好的鲁棒性,包括在室内和室外环境中直接用户控制的运动,以及作为分层控制堆栈中的运动层的集成。与未使用人类数据训练的Tabula Rasa RL策略的基准测试和消融研究确认,我们的框架产生了一种轻量级、可部署的策略,该策略能够从转向指令重构协调的全身行为,保留人类步态特征,同时保持鲁棒性和完全可调性。

Factorized Tactile Representation and Control for Sim-to-Real Manipulation

因子化触觉表示与控制用于仿真到现实的操作
Shang, Siqi, Aumann, Bianca, Brady, Tye, Migdal, Joshua, Padir, Taskin
Abstract
Tactile sim-to-real learning must bridge simulated contact and device-specific sensor responses while preserving information needed for control. We propose a factorized tactile representation and control framework that maps normal force and contact patch to an effective contact response recoverable from sensor readings. The response is separated into contact geometry, force distribution, and temporal contact change, with representation-specific encoding and randomization. A Tactile Gated Policy preserves these representations separately through control and operates over all mask configurations without retraining. We evaluate the approach through response reconstruction, spatial alignment, force regulation, and contact-rich adversarial peg insertion in simulation and the real world, enabling the utility and transfer reliability of different tactile representations to be assessed independently. The approach achieves <1 mm contact localization, 1.69 N force-tracking error on unseen geometries, and a 35% improvement in real-world adversarial peg insertion over the unfactorized response, with different tactile representations benefiting different interactions.

Rephrase Before You Act: Characterizing and Mitigating Language Sensitivity in Vision-Language-Action Models

行动前重述:特征化和减轻视觉-语言-行动模型中的语言敏感性
Watts, Mikey, Cui, Yuchen
Abstract
Vision-language-action models (VLAs) are strikingly sensitive to instruction phrasing and do not inherit the language robustness of the vision-language models they are built on. A one-word edit can move success by tens of points: $\pi_{0.5}$ turns on a LIBERO stove 100% of the time for "switch on the stove" and 2% for "switch on the hot plate", and a $\pi_0$ checkpoint finetuned with rephrase augmentation still shows swings of up to 61 points. We characterize this sensitivity with statistically tested single-edit swings and an oracle phrase search, which shows that phrasing alone nearly closes the 21-point gap between in-distribution and out-of-distribution tasks. We then reduce it without modifying the policy. Because the sensitivity is systematic, it can be expressed as explicit rules: we score many phrasings of a few training tasks, have a large language model distill the evidence into ten to twenty rephrasing rules, and at deployment rewrite each incoming instruction once under these rules. The rules improve the frozen $\pi_0$ by 16 to 27% relative on twelve held-out tasks across adversarial, VLM-generated, and human-generated phrasings, with gains concentrated on out-of-distribution tasks. The pipeline replicates on $\pi_{0.5}$ and LIBERO, lifting in-finetune success from 93.6% to 97.8%. The method requires no retraining and no per-step verification, and applies zero-shot to unseen tasks and instructions. Project website: https://sttawm.github.io/rephrase-before-you-act

视觉-语言-行动模型(VLA)对指令措辞表现出显著的敏感性,并未继承其基础视觉-语言模型的语言鲁棒性。单词的微小修改可以导致成功率的巨大变化:$ ext{π}_{0.5}$ 在“打开炉子”这一指令下的成功率为100%,而在“打开热板”下仅为2%;经过重述增强微调的$ ext{π}_0$检查点仍显示出高达61点的波动。我们通过统计测试的单编辑波动和一个oracle短语搜索来特征化这种敏感性,结果显示,仅凭措辞几乎可以弥补21点的分数差距,涵盖了分布内和分布外任务。随后,我们在不修改策略的情况下减少了这种敏感性。由于这种敏感性是系统性的,因此可以用明确的规则来表达:我们对少数训练任务的多种措辞进行评分,让一个大型语言模型将证据提炼为十到二十条重述规则,并在部署时根据这些规则对每个传入指令进行一次重写。这些规则使得冻结的$ ext{π}_0$在十二个保留任务上相对提高了16%到27%,这些任务包括对抗性、VLM生成和人类生成的措辞,收益主要集中在分布外任务上。该流程在$ ext{π}_{0.5}$和LIBERO上得以复制,将微调成功率从93.6%提升至97.8%。该方法无需重新训练,也不需要逐步验证,并且可以零样本应用于未见过的任务和指令。项目网站:https://sttawm.github.io/rephrase-before-you-act

Long-WAM: Scaling the Context of World-Action Models

Long-WAM:扩展世界-动作模型的上下文

Abstract
Real-time robot control demands enough visual history to infer motion and task progress, but processing that history can delay action. We present Long-WAM, a model-system framework for scaling the context of causal world-action models under real-time control constraints. Our central finding is that access to history is not the same as using it: longer histories pay off far more when the video foundation is pretrained autoregressively (AR). We first learn causal prediction from robot and egocentric videos without action labels, then preserve this history-to-future structure during world-action adaptation. On RoboCasa GR-1, increasing context from 0.0 to 19.2 seconds raises success from 63.3% to 78.7%, whereas a bidirectionally pretrained initialization shows no net gain; robot-domain AR pretraining further raises peak success on GR-1 and LIBERO-Long. Long-WAM also achieves the best results among compared methods on LIBERO-Long, RoboTwin 2.0, and DOMINO. Streaming observation encoding, asynchronous execution, and hardware-specific acceleration enable deployment on RTX 5090, DGX Spark, and Jetson AGX Thor without dropping future prediction; on RTX 5090, each action chunk, including future-video latent prediction, takes 107.4 ms. Real-time deployment on Unitree G1 and YAM supports dynamic and long-horizon manipulation, including 95% success on dynamic cup stacking, where Pi0.5 and Fast-WAM succeed in none of 20 trials. As a memory-informed executor, Long-WAM also complements higher-level planning in composite tasks.

实时机器人控制需要足够的视觉历史来推断运动和任务进展,但处理这些历史可能会延迟行动。我们提出了Long-WAM,这是一种在实时控制约束下扩展因果世界-动作模型上下文的模型系统框架。我们的核心发现是,访问历史并不等同于使用历史:当视频基础通过自回归(AR)预训练时,更长的历史带来的收益更大。我们首先从没有动作标签的机器人和自我中心视频中学习因果预测,然后在世界-动作适应过程中保持这种历史到未来的结构。在RoboCasa GR-1上,将上下文从0.0秒增加到19.2秒使成功率从63.3%提高到78.7%,而双向预训练的初始化则没有净增益;机器人领域的AR预训练进一步提高了GR-1和LIBERO-Long上的峰值成功率。Long-WAM在LIBERO-Long、RoboTwin 2.0和DOMINO等比较方法中也取得了最佳结果。流式观察编码、异步执行和硬件特定加速使其能够在RTX 5090、DGX Spark和Jetson AGX Thor上部署,而不会降低未来预测的准确性;在RTX 5090上,每个动作块(包括未来视频潜在预测)耗时107.4毫秒。Unitree G1和YAM上的实时部署支持动态和长时间范围的操作,包括在动态杯叠加中取得95%的成功率,而Pi0.5和Fast-WAM在20次试验中均未成功。作为一个受记忆启发的执行器,Long-WAM还补充了复合任务中的高层规划。

RoboPrompt: Intuitive Robot Policy Steering with Sparse Human Input

RoboPrompt:通过稀疏人类输入进行直观的机器人策略引导
Zou, Yanwen, Shi, Chenyang, Xu, Guoxuan, Yu, Wenye, Chen, Wendi, Pan, Ye, Lu, Cewu, Wen, Chuan
Abstract
End-to-end robot policies trained through imitation learning remain constrained by limited data diversity, making reliable zero-shot deployment in real-world settings challenging. Shared-autonomy methods enable human correction through teleoperation, but specialized hardware and operator training hinder deployment at scale. Other approaches incorporate human guidance as additional policy inputs, often requiring architectural changes and dedicated training for steerability, which limits their applicability across policies. We present RoboPrompt, a general-purpose, lightweight robot policy steering system that enables users to guide policy behavior through intuitive, sparse inputs, including drawn traces, target points, and coarse directional instructions. RoboPrompt decouples human-intention translation from the underlying policy: a reusable module converts human guidance into action drafts, which are refined through the diffusion or flow-matching dynamics of the base policy. By controlling action generation in noise space, RoboPrompt balances human intent with the policy prior without modifying the base policy architecture or fine-tuning it for steerability. Experiments demonstrate effective steering across Diffusion Policy, $\pi_{0.5}$, and FastWAM. We further use steered rollouts for online policy improvement through DAgger. After 2-3 rounds of iteration, average success rates increase by 15.5\% for $\pi_{0.5}$ across three tasks and by 21.3\% across three policies(Diffusion Policy, $\pi_{0.5}$, FastWAM) on the Insert Bread task, while average human intervention counts decrease by 44.0\% (2.86 to 1.60) and 81.9\% (2.60 to 0.47), respectively.

通过模仿学习训练的端到端机器人策略受到数据多样性有限的制约,使得在现实环境中可靠的零-shot 部署变得具有挑战性。共享自主方法通过遥控实现人类纠正,但专用硬件和操作员培训限制了大规模部署。其他方法将人类指导作为额外的策略输入,通常需要架构更改和专门训练以实现可引导性,这限制了它们在不同策略中的适用性。我们提出了 RoboPrompt,一种通用的轻量级机器人策略引导系统,使用户能够通过直观的稀疏输入(包括绘制轨迹、目标点和粗略方向指令)来引导策略行为。RoboPrompt 将人类意图的转换与基础策略解耦:一个可重用的模块将人类指导转换为行动草稿,这些草稿通过基础策略的扩散或流动匹配动态进行优化。通过在噪声空间中控制行动生成,RoboPrompt 在不修改基础策略架构或进行可引导性微调的情况下,平衡了人类意图与策略先验。实验表明,在扩散策略(Diffusion Policy)、$ ext{π}_{0.5}$ 和 FastWAM 上实现了有效的引导。我们进一步利用引导的回滚(steered rollouts)通过 DAgger 进行在线策略改进。在经过 2-3 轮迭代后,$ ext{π}_{0.5}$ 在三个任务上的平均成功率提高了 15.5\%,而在 Insert Bread 任务上,三个策略(扩散策略、$ ext{π}_{0.5}$、FastWAM)的成功率提高了 21.3\%,同时平均人类干预次数分别减少了 44.0\%(从 2.86 降至 1.60)和 81.9\\%(从 2.60 降至 0.47)。

Pre-training, Reasoning, Benchmarking: X-ray Report Generation on CheXpert Plus Dataset

预训练、推理、基准测试:基于CheXpert Plus数据集的X光报告生成
Wang, Xiao, Zhang, Yuxiang, Xu, Dan, Li, Yuehang, Wang, Shiao, Jiang, Bo, Wang, Yaowei, Tian, Yonghong, Tang, Jin
Abstract
X-ray image-based Radiology Report Generation (RRG) constitutes a critical research direction within medical artificial intelligence, with great potential to alleviate clinicians' diagnostic workload and shorten patient waiting periods. Despite substantial advances over recent years, the field faces evident bottlenecks stemming from insufficient standardized benchmarks and inadequate domain adaptation of generic large models. Notably, the newly released CheXpert Plus dataset is provided without accompanying baseline implementations and evaluation results, which impedes standardized training, quantitative evaluation and fair comparison among follow-up algorithms. To mitigate this limitation, we establish a comprehensive benchmark encompassing prevailing X-ray report generation models and Large Language Models on CheXpert Plus. This benchmark delivers a reliable comparative foundation for upcoming methods and enables researchers to rapidly identify state-of-the-art approaches within this domain. Beyond benchmark construction, we rethink X-ray RRG under the paradigm of large models and propose a novel framework termed MambaXray-PRB. Our framework improves report generation performance and enhances model interpretability via multi-stage large-model pre-training and multi-modal Chain-of-Thought reasoning. The pipeline consists of three successive phases: self-supervised auto-regressive modeling, X-ray-report contrastive learning, and post-training optimization for reasoning and report generation. Extensive experiments on IU X-ray, MIMIC-CXR, and CheXpert Plus datasets validate the effectiveness of MambaXray-PRB for radiology report generation.

Autonomous Driving Research Requires a Community-Driven Data Paradigm

自主驾驶研究需要以社区为驱动的数据范式
Yoo, Jinsu, Huang, Zanming, Luo, Katie Z, Mai, Zheda, Wu, Qiyuan, Hariharan, Bharath, Campbell, Mark, Chao, Wei-Lun
Abstract
Autonomous driving has made remarkable progress, with recent AI advances enabling commercial deployments that are reshaping urban mobility. Yet the field remains far from its universal social promise: autonomous systems that can operate robustly anywhere, anytime, for anyone. We posit that this gap is not merely a modeling problem, but a problem of the prevailing data paradigm. Current research relies heavily on a few benchmark datasets with limited spatial and scenario coverage, even though the community has collectively produced over 600 autonomous driving datasets across nearly 50 countries. However, this abundance has not translated into broad research impact: most datasets remain significantly underused due to fragmentation, limited visibility, incompatible protocols, and benchmark incentives that concentrate attention on a few dominant datasets. We therefore argue that autonomous driving research requires a collaborative, community-driven data paradigm. Such a paradigm would improve the discovery, reuse, integration, and evaluation of diverse datasets; make underexplored data easier and more rewarding to study; and lower the barrier for new contributors. We outline its key principles, illustrate an early realization, and call for collaboration across academia and industry to transform fragmented datasets into shared community infrastructure for anytime-anywhere autonomy.

PanoPed: Beyond Bounding Boxes for Sim-to-Real Panoramic Pedestrian Tracking

PanoPed:超越边界框的全景行人跟踪从仿真到现实
Zhu, Qinfeng, Zhao, Weiguang, Jiang, Yunxi, Nguyen, Anh, Fan, Lei
Abstract
Full-sphere panoramic cameras let fixed monitoring systems and mobile robots track people in every direction, but a planar bounding box does not fully describe where a person is on the sphere. We introduce PanoPed, a sim-to-real benchmark for pedestrian tracking on the full sphere. PanoPed-S contains 108,000 frames from fixed, quadruped-mounted, and drone-mounted cameras, with synchronized masks, depth, camera poses, and 3D pedestrian states. PanoPed-R adds 28,002 real frames from fixed cameras, 16,247 of them densely annotated. We find that an ERP rectangle cannot uniquely determine the spherical center and angular extent of the visible person, while the detector's visual query still carries information about them. Inspired by the sextant's use of angular measurements to locate objects, we propose Sextant, a plug-and-play angular localization head with only about 0.035M parameters. It reuses a frozen detector, keeps track identities unchanged, and needs no extra image encoder. Sextant gives the best result in our PanoPed-S test comparison, raising the strongest baseline, MOTIP, from 47.30 to 49.49 HOTA, with gains on all eight test sequences. Without fine-tuning on real data, the same synthetic-trained heads improve MOTIP and HAT by 0.96-1.14 HOTA on real video, and both seeds improve every real sequence. HAT+Sextant scores best among the compared systems that add no localization image encoder.

MoR-MLLM: Mixture of Recursions for Efficient Multimodal Large Language Models

MoR-MLLM:高效多模态大语言模型的递归混合
Zheng, Pengcheng, Zhang, Chaoning, Yan, Jiaxin, Cao, Sihan, Zhang, Jianwei, Wang, Xudong, Zhang, Jiaquan, Lee, Jewon, Kim, Tae-Ho, Yang, Yang, Shen, Heng Tao
Abstract
Multimodal Large Language Models (MLLMs) have demonstrated remarkable reasoning capabilities across vision and language tasks. However, their massive computational and memory demands hinder real-world deployment. While recent efforts reduce costs by employing lightweight language backbones, existing paradigms remain computation-dense due to their static sparsity and depth allocation, which cannot adapt to the semantic complexity of each token. To this end, we propose MoR-MLLM, a computation-sparse MLLM based on the recent Mixture-of-Recursions (MoR) framework. MoR-MLLM introduces adaptive per-token recursion, allowing the model to dynamically adjust its recursive depth and allocate more computation to visually or linguistically challenging tokens while skipping redundant operations for simpler ones. To stabilize the training of recursive sparsity in multimodal settings, we further design a three-stage MoR-Tuning strategy and an entropy-regularized loss to encourage diverse routing distributions. Extensive experiments show that compared with recent advanced tiny MLLMs, our proposed MoR-MLLM can greatly reduce the training memory and computation complexity while retaining high performance on various vision-language tasks.

多模态大语言模型(MLLMs)在视觉和语言任务中展现了卓越的推理能力。然而,它们巨大的计算和内存需求阻碍了在实际应用中的部署。尽管近期的研究通过采用轻量级语言骨干网络来降低成本,但现有范式由于其静态稀疏性和深度分配,仍然计算密集,无法适应每个标记的语义复杂性。为此,我们提出了MoR-MLLM,这是一种基于最近的递归混合(Mixture-of-Recursions, MoR)框架的计算稀疏MLLM。MoR-MLLM引入了自适应的每标记递归,使模型能够动态调整其递归深度,并为视觉或语言上具有挑战性的标记分配更多计算,同时跳过对简单标记的冗余操作。为了稳定多模态环境中递归稀疏性的训练,我们进一步设计了三阶段的MoR调优策略和熵正则化损失,以鼓励多样化的路由分布。大量实验表明,与近期先进的小型MLLM相比,我们提出的MoR-MLLM在保持高性能的同时,能够大幅降低训练内存和计算复杂度,适用于各种视觉-语言任务。

VCR-Bench: A Modular Open-Source Benchmark for Video Classification Robustness

VCR-Bench:一个模块化的开源视频分类鲁棒性基准
Plinskiy, Maksim, Gushchin, Aleksandr, Lavrushkin, Sergey, Vatolin, Dmitriy S., Antsiferova, Anastasia
Abstract
Robustness of image classification has several benchmarks, but their video counterparts are absent. In video classification temporal dimension introduces additional degrees of freedom for adversarial attacks, defenses, and preprocessing. Temporal sampling, perturbation budgets, and metric aggregation also interact in ways with no direct analogue in the image setting. Therefore, robustness for video classifiers is studied across scattered, incompatible implementations, making reported numbers hard to reproduce and analyze.

SPW-Nav: A Streaming Panoramic World Model for Language-Guided Navigation

SPW-Nav:一种用于语言引导导航的流式全景世界模型
Liu, Yunheng, Cai, Ziqi, Yang, Siqi, Wang, Yimu, Teng, Minggui, Tan, Jiaming, Weng, Shuchen, Wu, Erwin, Zhang, Kaipeng, Shi, Boxin
Abstract
Language-guided panoramic video generation benefits various downstream applications, such as interactive 3D scene exploration, virtual reality experiences, and embodied agent training. Existing panoramic generators follow predefined trajectories, and interactive world models act through low-level actions in perspective views. We propose SPW-Nav, a streaming panoramic world model that understands movement instructions and streams one minute of 2K 360-degree video in real time from a single panorama. SPW-Nav interprets each instruction in the previously generated panorama as camera motion. Spherical rotation decoupling applies rotation exactly on the sphere, pose-aligned conditioning keeps translation inputs bounded over long streams, and a multi-term memory with a few-step generator continues the scene as instructions change. We also build SPW-NavSet, panoramic videos with camera trajectories and verified instructions. Driven by language, SPW-Nav outperforms prior panoramic generators in camera-following accuracy and video quality, and supports on-the-fly instruction switching.

One-Slide Calibration of Pathology Foundation Models

病理基础模型的一次性校准
Hou, Ming Ren, Huang, Tianyi
Abstract
Scanner variation changes how pathology foundation models represent the same tissue. We introduce SlideRuler, which uses regions within a slide as internal controls to estimate and correct acquisition-induced shifts in other regions. A transfer map learned from paired rescans enables calibration from a single scan at inference while keeping the foundation model fixed. Across two encoders and five SCORPION scanners, learned transfer reduces mean target-to-source embedding distance by 16.3-38.5% relative to raw embeddings. Comparisons with unrelated same-scanner controls reveal a positive same-slide contribution across all four evaluation settings, including scanner holdout. A source-anchored variant reduces source-feature displacement by 47.7-83.6% relative to learned transfer while retaining most of its alignment gain. By drawing calibration information from the slide itself, SlideRuler offers a path toward more consistent use of frozen pathology models across imaging systems.

RACER: Reflective Agent Coupling Query Interpretation and Tool-Based Retrieval for Frame Selection in Long Video Understanding

RACER:反思性代理耦合查询解释与基于工具的检索用于长视频理解中的帧选择
Huang, Yiyang, Zhang, Yitian, Wang, Yizhou, Lu, Jianglin, Dong, Qihua, Wang, Hailing, Zeng, Huimin, Zhang, Mingyuan, Fu, Yun
Abstract
Video large language models (Vid-LLMs) excel at diverse video-language tasks by reasoning over selected frames. However, frame selection for long videos remains challenging, as it requires retrieving relevant frames distributed across segments from a large candidate pool given complex queries. This paper investigates dominant approaches to long-video frame selection from a task-decomposition perspective, identifying two key challenges: the Query Comprehension Gap in similarity-based methods and the Interpretation--Selection Gap in judgment-based methods. To address them, we propose RACER, a training-free reflective agentic framework that decomposes long-video frame selection into query interpretation driven by a lightweight Vid-LLM and evidence localization supported by an embedding model serving as a retrieval tool. Specifically, the Vid-LLM is responsible solely for reformulating the complex query into sub-queries that make implicit information requirements explicit, mitigating the Query Comprehension Gap. Meanwhile, the retrieval tool leverages these sub-queries to localize relevant evidence, relieving the Vid-LLM of direct frame selection and thus addressing the Interpretation--Selection Gap. Finally, the retrieved frames are fed back to the Vid-LLM for sub-query refinement, forming a reflection loop that iteratively improves query interpretation and frame selection. Experiments across multiple benchmarks show that RACER consistently improves long video understanding. Notably, RACER achieves effective frame selection even with limited-capability components, demonstrating that agentic integration enables these components to enhance more capable Vid-LLMs.

视频大型语言模型(Vid-LLMs)通过对选定帧的推理,在多种视频语言任务中表现出色。然而,对于长视频的帧选择仍然具有挑战性,因为这需要从一个大型候选池中检索分布在不同片段中的相关帧,以应对复杂的查询。本文从任务分解的角度探讨了长视频帧选择的主要方法,识别出两个关键挑战:基于相似性的查询理解差距和基于判断的解释-选择差距。为了解决这些问题,我们提出了RACER,一个无训练的反思性代理框架,将长视频帧选择分解为由轻量级Vid-LLM驱动的查询解释和由嵌入模型支持的证据定位,后者作为检索工具。具体而言,Vid-LLM仅负责将复杂查询重新表述为使隐含信息需求显性化的子查询,从而缓解查询理解差距。同时,检索工具利用这些子查询来定位相关证据,减轻Vid-LLM的直接帧选择负担,从而解决解释-选择差距。最后,检索到的帧被反馈给Vid-LLM以进行子查询的细化,形成一个反思循环,迭代改善查询解释和帧选择。在多个基准测试中的实验表明,RACER在长视频理解方面持续取得改善。值得注意的是,RACER即使在能力有限的组件下也能实现有效的帧选择,证明了代理集成使这些组件能够增强更强大的Vid-LLM。

S2Tok: Streaming 3D Gaussian Reconstruction with Persistent Spatial Tokens

S2Tok:具有持久空间标记的流式三维高斯重建
Li, Fang, Yenphraphai, Jiraphon, Herau, Quentin, Meng, Depu, Hu, Yihan, Xu, Tianshuo, Ahuja, Narendra, Zhan, Wei
Abstract
Streaming 3D reconstruction requires more than a sequence of geometric predictions: it requires a persistent scene state that can incorporate new evidence and remain renderable as observations arrive. Latent spatial tokens offer a promising representation for this purpose, but constructing them from an image collection leaves open how to maintain them online, where each observation may both revisit known regions and reveal new content. We introduce S2Tok, a feed-forward framework that maintains a size-adaptive, persistent scene state from uncalibrated image streams. Its central idea is to distinguish updates to the existing representation from selective expansion. A spatially informed transformer integrates each incoming observation with the persistent scene tokens, while a learned admission module selectively expands the representation to limit redundant storage. A hierarchical decoder and Gaussian head convert the evolving state into non-pixel-aligned 3D Gaussians, enabling novel-view rendering without caching previous frames. Experiments across four benchmarks demonstrate competitive streaming rendering quality with compact Gaussian representations. These results support latent spatial tokens as a persistent computational state for online 3D reconstruction, combining learned scene updates with explicit Gaussian rendering.

流式三维重建不仅需要一系列几何预测,还需要一个能够整合新证据并在观察到达时保持可渲染的持久场景状态。潜在空间标记为此提供了一种有前景的表示方式,但如何从图像集合中构建它们,并在在线环境中维护它们仍然是一个未解的问题,因为每个观察可能既会重访已知区域,又会揭示新内容。我们提出了S2Tok,这是一种前馈框架,能够从未校准的图像流中维护一个大小自适应的持久场景状态。其核心思想是将对现有表示的更新与选择性扩展区分开来。一个空间信息驱动的变换器将每个输入观察与持久场景标记相结合,而一个学习的接纳模块则选择性地扩展表示,以限制冗余存储。一个层次解码器和高斯头将不断演变的状态转换为非像素对齐的三维高斯,从而实现新视角渲染而无需缓存先前的帧。在四个基准测试中的实验表明,使用紧凑的高斯表示实现了具有竞争力的流式渲染质量。这些结果支持潜在空间标记作为在线三维重建的持久计算状态,将学习的场景更新与显式高斯渲染相结合。

Zero-Shot Brain MRI Inpainting with 2.5D Unconditional Flow Priors

基于2.5D无条件流先验的零-shot脑MRI修复
Hadzic, Arnela, Thaler, Franz, Joham, Simon Johannes, Urschler, Martin
Abstract
Generative inpainting of brain MRI volumes is essential for synthesizing healthy tissue in pathological regions, improving the accuracy and reliability of automated downstream brain analysis applications such as image registration, brain extraction, and segmentation. However, standard 3D approaches are computationally prohibitive, while efficient 2D slice-wise methods suffer from severe inter-slice discontinuities. Furthermore, traditional models rely on conditional training, requiring task-specific learning of masked inputs. We propose a zero-shot brain MRI inpainting framework utilizing 2.5D unconditional flow priors to capture spatial context along the superior-inferior axis without the overhead of full 3D convolutions. During training, our flow matching model learns the joint distribution of adjacent axial slice triplets, modeling the manifold of healthy brain anatomy while explicitly excluding pathological regions from the loss function. At inference, the model processes the input triplets autoregressively along the depth axis. We employ the Restora-Flow solver to constrain the unconditional prior using the input mask, achieving accurate zero-shot inpainting. Evaluations show our 2.5D strategy resolves the structural discontinuities of 2D baselines, synthesizing plausible healthy tissue while maintaining volumetric consistency across the axial, sagittal, and coronal planes. As a final step, we generate and average an ensemble of multiple stochastic reconstructions to form the final prediction. Quantitative results benchmarked on the official BraTS 2026 Inpainting Challenge validation set demonstrate the effectiveness of our proposed approach, yielding an SSIM of 0.816 $\pm$ 0.112, MSE of 0.007 $\pm$ 0.005, and PSNR of 22.923 $\pm$ 4.343.

Personalize at Test Time: Learning User Preferences for Image Generation

测试时个性化:学习用户偏好以进行图像生成
Bai, Jiamu, Hu, Jiaming, Wu, Yanhong, Wang, Zellux
Abstract
Diffusion models can generate high-quality images, yet aligning their outputs with individual user preferences remains challenging. A key bottleneck is accurately modeling diverse user preferences from limited feedback. Existing approaches often rely on labor-intensive manual preference annotations or vision-language models (VLM) to extract preference information from user interaction histories, introducing substantial annotation or computational costs that limit scalability. We propose an approach that learns personalized reward models directly from users' historical image preference pairs. First, we use an autoencoder to compress hundreds of visual attributes into 50 attribute-anchored preference dimensions and train an evaluator to score images along these dimensions. We then represent each user's preferences as a linear combination of the shared dimension scores, estimating the user-specific weights by maximizing the likelihood of their observed pairwise preferences under the Bradley-Terry model. This formulation reduces per-user adaptation to optimizing a low-dimensional weight vector, simplifying optimization and enabling data-efficient personalization from sparse feedback. The learned personalized rewards guide image generation at inference time while keeping the diffusion model frozen. Experiments on real-user preference data show that our approach achieves approximately 77% held-out pairwise preference prediction accuracy and improves the alignment of generated images with individual user preferences.

Beyond Explanation: Debugging Medical Imaging Models via Concept Intervention

超越解释:通过概念干预调试医学影像模型
Thapa, Samrajya, Quest, Daniel J., Kline, Timothy L., Langstraat, Carrie L., Trabuco, Emanuel C., Le, Wei
Abstract
Medical imaging models often operate as black boxes, limiting interpretability and systematic debugging. We introduce an easy-to-use, plug-and-play framework for concept-based interpretation and model refinement. By aligning a single-modality encoder to BioMedCLIP, we construct a Concept Bottleneck Model (CBM) that enables concept-level interventions. These interventions allow us to isolate causal versus spuriously correlated concepts, validate insights with domain experts, and generate counterfactual samples for targeted fine-tuning. We evaluate our framework on a Mayo Clinic ultrasound dataset and the CheXpert 5x200 chest X-ray dataset. Results demonstrate that concept intervention enables reliable model diagnosis while maintaining, and occasionally improving predictive performance via guided fine-tuning. Our findings highlight the practical value of this framework for controlled, interpretable refinement of clinical deep learning models.

Shape-Bayes: Bayesian Inference of Structured Shapes under Visual Ambiguity

Shape-Bayes:在视觉模糊下的结构形状贝叶斯推断
Tellamekala, Mani Kumar, Brown, Tosh, Valstar, Michel
Abstract
Perceiving structured shapes, such as human faces, from pixels is an inherently ambiguous task in real-world conditions. Yet, shape inference is largely posed as a deterministic regression task predicting fixed spatial coordinates. We find that deterministic regression is brittle when visual evidence is ambiguous or incomplete; under severe occlusions deterministic models exhibit structural collapse, predicting incoherent shapes or reverting to generic averages. To address this, we introduce Shape-Bayes, a probabilistic framework that couples uncertainty-aware visual perception with Bayesian shape reasoning. Rather than forcing point estimates, Shape-Bayes dynamically weights visual evidence against geometric priors to infer a structurally valid shape posterior. Demonstrated on human face shape regression, a rigorous testbed featuring complex non-rigid deformations and strict anatomical constraints, Shape-Bayes comprises: (1) a base model predicting noisy landmarks alongside distilled aleatoric uncertainties; (2) a lightweight Transformer encoding these observations into an adaptive prior over a PCA shape manifold; and (3) a differentiable Bayesian solver computing closed-form posteriors by balancing the noisy predictions against this prior. By guaranteeing complete structural integrity, Shape-Bayes achieves an absolute improvement of up to ~34% IDR over state-of-the-art deterministic models. Simultaneously, it yields highly calibrated uncertainty bounds and reduces relative error by up to 12.5%, establishing a new state-of-the-art for robust 2D face shape regression under severe occlusion.

在现实条件下,从像素中感知结构形状(如人脸)是一项固有的模糊任务。然而,形状推断通常被视为一个确定性回归任务,旨在预测固定的空间坐标。我们发现,当视觉证据模糊或不完整时,确定性回归模型表现脆弱;在严重遮挡的情况下,确定性模型会出现结构崩溃,预测出不连贯的形状或回归到通用平均值。为了解决这个问题,我们提出了Shape-Bayes,一个将不确定性感知视觉感知与贝叶斯形状推理相结合的概率框架。Shape-Bayes并不是强制进行点估计,而是动态地将视觉证据与几何先验进行加权,以推断出结构有效的形状后验。在人脸形状回归的严格测试平台上,Shape-Bayes展示了其有效性,该平台具有复杂的非刚性变形和严格的解剖约束。Shape-Bayes包括:(1) 一个基础模型,预测噪声标记并提取随机不确定性;(2) 一个轻量级Transformer,将这些观察结果编码为PCA形状流形上的自适应先验;(3) 一个可微分的贝叶斯求解器,通过平衡噪声预测与该先验,计算闭式形式的后验。通过确保完整的结构完整性,Shape-Bayes在相较于最先进的确定性模型上实现了最高约34%的绝对改进。同时,它提供了高度校准的不确定性界限,并将相对误差降低了最高12.5%,在严重遮挡下建立了稳健的2D人脸形状回归的新最先进水平。项目页面为:https://shape-bayes.github.io。

GUARD: Geometric Uncertainty-Aware Point Cloud Denoising and Segmentation for Robotic Hard Disk Drive Disassembly

GUARD:用于机器人硬盘驱动器拆卸的几何不确定性感知点云去噪与分割
Wang, Zuoxu, Liang, Xiao
Abstract
Reliable robotic disassembly requires part-level representations that distinguish genuine component geometry from scanning and reconstruction artifacts. In point clouds of hard disk drives (HDDs), structured ghost artifacts can resemble valid components locally while remaining inconsistent with the overall geometry, allowing erroneous measurements to receive plausible semantic labels. This creates an engineering information problem: semantic prediction confidence alone does not establish whether the underlying geometry is reliable. We propose \textbf{GUARD}, a geometric uncertainty-aware framework that performs point filtering and segmentation within a single forward pass by modeling the reliability of learned geometric representations. GUARD combines a multi-scale geometric transformer with a multi-bandwidth random Fourier feature Gaussian Process to estimate per-point geometric uncertainty, complemented by predictive entropy to suppress unreliable measurements while preserving informative structures. Evaluation on 2,745 real HDD point clouds shows that GUARD improves PointNet++ segmentation mean intersection over union from 0.7739 to 0.8318. Additional experiments on ShapeNetPart and ScanNet examine robustness across corruption types, point-cloud domains, and segmentation backbones. On manually annotated ScanNet samples, geometric uncertainty achieves a corrupted-point detection F1 score of 0.7931, compared with 0.2212 for predictive entropy. The results demonstrate the value of distinguishing geometric reliability from semantic confidence and reveal a tradeoff between artifact suppression and preservation of informative structures. GUARD contributes a reliability-aware approach to interpreting imperfect 3D measurements for component identification and subsequent robotic handling.

Abstract
Layout-to-Image generation has made substantial progress in spatial and object-level control. However, existing methods still struggle with complex scenes containing many overlapping and interacting objects. We argue that training data is a particular bottleneck: existing datasets lack examples with dense, complex object interactions. To address this gap, we introduce OverLay++, a large-scale Layout-to-Image dataset with structurally complex scenes. OverLay++ contains approximately 500K images with an average of 6.6 objects per image, exceeding existing datasets by 1.67 times in annotation density. Beyond annotation density, OverLay++ provides rich semantic detail with object captions over six times longer than in current datasets. Our dataset generation pipeline is simple and produces dense, overlapping object annotations with rich per-object captions. Across multiple benchmarks, state-of-the-art Layout-to-Image methods trained on the OverLay++ dataset show consistent improvement and faster convergence, demonstrating the importance of dense, overlap-aware, and caption-rich supervision for controllable image generation.

Abstract
Diffusion-based image super-resolution (SR) can create visually plausible detail that is not supported by the low-resolution input. We introduce DISRQAD, a subjective-quality dataset and diagnostic benchmark for this setting. It contains mean opinion scores (MOS) for 14,000 SR outputs from ten diffusion and four non-diffusion methods, spanning four low-resolution degradation conditions and x2/x4 upscaling. We evaluate 51 standard full-reference and no-reference metric configurations and 11 adapted variants. Agreement with MOS is substantially weaker on diffusion outputs: the strongest standard no-reference baseline reaches 0.431 SRCC on diffusion SR versus 0.813 on non-diffusion SR. As a case study in benchmark use, a pruned and distilled Q-ReAlign-mini student reaches 0.496 SRCC on diffusion SR. DISRQAD measures perceived output quality, not faithfulness to the input; it enables analysis of metric behavior across generator families and input conditions. Our findings reveal a substantial gap in the assessment of diffusion-based SR and provide a basis for developing quality models sensitive to diffusion-specific artifacts.

Anaximander: Interactively Running Geospatial Deep Learning Models on Any Compute Backend

阿那克西曼德:在任何计算后端上交互式运行地理空间深度学习模型
Soman, Satej S., Zaytar, Akram, Tadesse, Girmaw A., Hacheme, Gilles Q., Danish, Muhammad S., Becker-Reshef, Inbal, Dodhia, Rahul, Ferres, Juan Lavista
Abstract
Applying deep learning models to satellite imagery from within geographic information systems (GIS) remains high-friction for remote sensing practitioners. Models arrive in incompatible formats and target different compute environments, from local workstations to serverless cloud services. As a result, every evaluation demands custom deployment, tiling, and georeferencing code before a single prediction reaches the analyst's map. This friction discourages systematic comparison in a domain where model choice directly affects operational outcomes such as field delineation, crop monitoring, and disaster response. We present Anaximander, an open-source system that unifies model source and compute location choice behind one interactive interface. The system's backend is an inference server that loads models from multiple commonly-used sources and serves them on any accessible compute backend. The server provides session management and model caching, and streams results back per tile. The backend is paired with a QGIS plugin that drives tiling, result reassembly, georeferencing, and real-time per-tile status visualization. An additional user-interface path injects layer legends as prompts into vision-language models. We demonstrate the system in a code-free side-by-side comparison of three heterogeneous models on an agricultural field delineation task: gpt-image-1 via a cloud API, Segment Anything Model 3 (SAM3) on a remote GPU, and DelineateAnything on a local CPU.

在地理信息系统(GIS)中应用深度学习模型于卫星图像仍然对遥感从业者造成较大阻力。模型以不兼容的格式出现,并针对不同的计算环境,从本地工作站到无服务器云服务。因此,每次评估都需要定制的部署、切片和地理参考代码,才能让单个预测到达分析师的地图。这种阻力使得在一个模型选择直接影响操作结果(如地块划分、作物监测和灾害响应)的领域中,系统比较变得困难。我们提出了阿那克西曼德(Anaximander),一个开源系统,通过一个交互式界面统一了模型源和计算位置的选择。该系统的后端是一个推理服务器,可以从多个常用源加载模型,并在任何可访问的计算后端上提供服务。服务器提供会话管理和模型缓存,并按切片流回结果。后端与一个QGIS插件配对,负责切片、结果重组、地理参考和实时每切片状态可视化。另一个用户界面路径将图层图例作为提示注入到视觉-语言模型中。我们在一个农业地块划分任务中演示了该系统,进行了无代码的并排比较,涉及三种异构模型:通过云API的gpt-image-1、在远程GPU上的Segment Anything Model 3(SAM3)和在本地CPU上的DelineateAnything。推理后端和协议是开源的,已在https://github.com/microsoft/nxmndr上提供。

SPLATIFY: Reproduce, Discover, Innovate! From Papers and Ideas to Trainable 3DGS Code

SPLATIFY:重现、发现、创新!从论文和想法到可训练的 3DGS 代码
Jain, Seemandhar, Gupta, Keshav, Chandraker, Manmohan
Abstract
The rapid growth of 3D Gaussian Splatting (3DGS) research demands significant effort to reimplement papers before building on them. We introduce SPLATIFY, a multi-agent framework that converts 3DGS papers into trainable gsplat-based implementations, where generic paper-to-code methods and frontier models fail. SPLATIFY achieves this through five innovations: (1) A context-free grammar for gsplat over a modular method template with extension points for losses, densification, rendering, and optimization, constraining synthesis so generated code satisfies gsplat's architectural invariants by construction. (2) Architectural elements for faithful reproduction: fork-aware citation recovery retrieving component-level code at function-level granularity, Graph-of-Thought synthesis in topological dependency order, RAG-guided in-context example selection from over 20 verified implementations, and visual feedback combining PSNR-guided regeneration, Gaussian-level structural checks, and VLM-driven patching. (3) Knowledge-driven compositional improvement that autonomously finds weaknesses and composes complementary regularizers, losses, and densification strategies to improve upon original results. (4) Interdisciplinary method discovery where agents retrieve physical priors from outside the 3DGS literature and compose them with rendering knowledge to produce methods for previously unaddressed scene types. (5) SPLATIFY-Bench, an evaluation framework across 30 diverse 3DGS papers. On papers without public code, SPLATIFY matches expert implementations while reducing development time from weeks to minutes, and through compositional discovery further improves PSNR by up to 2.4 dB. We additionally demonstrate novel methods for volumetric nebula rendering and other scientific domains, synthesized entirely by SPLATIFY.

TopoCurve: Geometry-Aware Topology Reasoning via B\'ezier Curves in Autonomous Driving

TopoCurve:基于贝塞尔曲线的几何感知拓扑推理在自动驾驶中的应用
Deaconu, Mihai Bogdan, Dioşan, Laura
Abstract
Topology reasoning jointly detects 3D lanes and traffic elements from multi-view images and infers their structural connectivity. Current methods model lanes as discrete polylines, lacking smoothness, analytical tangent directions, and global spatial support for attention, while providing sparse topology supervision. We propose TopoCurve, a geometry-driven architecture for 3D topology reasoning grounded in a structured parametric lane representation. Lanes are modeled as endpoint-fixed cubic B\'ezier curves, enabling continuous geometry with exact endpoints and analytically defined directionality. We exploit this shared curve geometry across the entire pipeline. Endpoint distance and tangent alignment are encoded with multi-scale Fourier features and injected into the topology head. Sampled curve points serve as geometry-aligned references for deformable cross-attention spanning the full lane. Parallel curve-anchored attention branches provide diverse predictions for one-to-many topology supervision. These components form a tightly coupled cascade where representation enables geometric reasoning, guides feature aggregation, and supports denser supervision. TopoCurve achieves 50.6 OLS on the OpenLane-V2 benchmark without any post-processing, establishing a new state-of-the-art among end-to-end camera-only methods, and outperforms all existing approaches on endpoint detection (56.8 vs. 52.6 on DET_p).

Depth-to-RGB: Repurposing a Frozen Depth Estimator for Geometry-Guided Compositing

深度到RGB:重新利用冻结的深度估计器进行几何引导合成
Jo, Sanghyun, Lim, Chae Yeon, Lee, Donghwan, Kim, Sihyun, Kim, Soo Ye, Kim, Kyungsu
Abstract
Reference-based object compositing inserts or replaces an object using a background image, a reference image, and a 2D compositing mask. These inputs guide appearance and placement but leave the completed scene's geometry implicit, which can distort object structure or alter the surroundings. Our Depth-to-RGB (D2R) framework predicts composite depth for a scene not yet observed in the RGB inputs. It learns reference-conditioned corrections to a frozen depth estimator using encoder features of paired completed scenes as targets. The unchanged decoder maps the corrected representation to the intended scene's depth, which a separately trained renderer holds fixed during RGB synthesis. Under matched architecture and training, encoder-feature supervision reduces OOD Stage-1 AbsRel by 31.4% relative to decoded-depth supervision. We also introduce AnyInsertion++ with paired in-distribution and category-disjoint splits to evaluate generalization beyond compositing training categories. The complete D2R system leads 12 open-source and 3 closed-source baselines in estimator-derived geometry and photometric quality on both paired splits. On category-disjoint data, D2R reduces AbsRel by 43.7% and improves PSNR by 2.4 dB over the matched RGB baseline. Across three unpaired benchmarks, D2R leads both identity metrics and reduces mean CLIP reference cosine distance by 55% relative to the strongest baseline.

RDGSplat: Render-Dedicated Geometry for Novel View Synthesis

RDGSplat:用于新视图合成的渲染专用几何体
Zheng, Zhijie, Xiang, Xinhao, Zhang, Jiawei
Abstract
3D foundation models enable efficient novel view synthesis by carrying a Gaussian head on the representation they already use for reconstruction. However, the views they render fall short of the geometry they recover, because that geometry is estimated under a metric objective and never scored on how it renders. Recent methods alleviate this by updating the backbone weights, but they thereby discard the metric predictions the model was built for and must be repeated for every new backbone. To this end, we propose RDGSplat, a framework that decodes a second geometry dedicated to rendering from a frozen 3D foundation model, leaving its metric predictions intact. In particular, we devise Render-Dedicated Geometry Decoding, which duplicates the pretrained decoders and optimizes the duplicates under photometric supervision alone. Then, a Target-Pose Conditioned Adapter is introduced to reformulate the representation those decoders read, conditioned on the target camera pose rather than the target image. Extensive experiments show that RDGSplat improves novel view synthesis across three feed-forward backbones on four benchmarks, with every pretrained weight frozen. On RE10K, it raises WM2.0 from 20.918 to 24.266\,dB while training 205.5\,M added parameters against a frozen 1.4\,B backbone, and the depth and pose the same model predicts are unchanged.

3D基础模型通过在其用于重建的表示上携带高斯头,实现了高效的新视图合成。然而,它们渲染的视图与恢复的几何体之间存在差距,因为该几何体是在度量目标下估计的,并未根据其渲染效果进行评分。最近的方法通过更新主干网络权重来缓解这一问题,但这也导致模型原本构建的度量预测被丢弃,并且每个新的主干网络都必须重复这一过程。为此,我们提出了RDGSplat,一个从冻结的3D基础模型中解码专用于渲染的第二几何体的框架,同时保持其度量预测不变。具体而言,我们设计了渲染专用几何体解码(Render-Dedicated Geometry Decoding),该方法复制预训练解码器,并仅在光度监督下优化这些副本。然后,引入了目标姿态条件适配器(Target-Pose Conditioned Adapter),以根据目标相机姿态而非目标图像重新构造这些解码器读取的表示。大量实验表明,RDGSplat在四个基准测试中提高了三种前馈主干网络的新视图合成性能,且每个预训练权重均保持冻结。在RE10K上,它将WM2.0从20.918提高到24.266 dB,同时训练205.5 M的新增参数,而冻结的1.4 B主干网络预测的深度和姿态保持不变。

One Frame, Full Heartbeat: ECG-Free 4D Cardiac Cine MRI Synthesis via Radial-Decomposed Flow Matching

一帧,全心跳:通过径向分解流匹配实现无心电图的4D心脏电影MRI合成
Wang, Shiyi, Sun, Ruochen, Li, Xiang, Liu, Peirong, Xing, Fangxu
Abstract
Cine cardiovascular magnetic resonance (CMR) captures the cardiac cycle as a four-dimensional (4D) sequence, but standard acquisition requires electrocardiogram (ECG) gating and repeated breath holds. Visual realism alone does not establish accurate patient-specific ejection fraction (EF) or ventricular volumes. We present PhaseFlow3D, a generative framework that synthesizes a complete 4D cine sequence from a single end-diastolic (ED) three-dimensional (3D) volume without ECG. To capture asymmetric systolic and diastolic dynamics, it represents the cardiac cycle as a piecewise linear phase anchored at ED and end-systolic (ES) time points. At inference, a population-level canonical template supplies this phase without patient-specific temporal information. A phase-conditioned rectified flow model generates a cardiac motion trajectory in latent space. Radial Contraction Decomposition converts each latent state into a 3D displacement field, combining a physics-informed radial component for centripetal myocardial contraction with an image-conditioned residual for rotation and out-of-plane motion. Each frame is generated by directly warping the ED volume, bypassing variational autoencoder decoding. On the combined ACDC and M&Ms benchmark, PhaseFlow3D achieves the lowest EF mean absolute error, the only positive left-ventricular volume-curve $R^2$, and the best distributional quality among compared methods. Ablations confirm each component's contribution. Downstream evaluations demonstrate the utility of the synthesized sequences and displacement fields for segmentation, pathology classification, label propagation, and myocardial strain analysis.

R-CNN-Based Chess Position Recognition

基于 R-CNN 的国际象棋棋局识别
Govind, Paras, Arandjelović, Ognjen
Abstract
Performing chess game position recognition solely from a single image of a three-dimensional board requires predicting the position and orientation of the board relative to the camera, the occupancy of squares and the piece type, which includes its colour. We propose an R-CNN-based framework with independent components for piece recognition and board geometry estimation, whose predictions are combined to reconstruct the position. For piece recognition, we adapt Faster R-CNN using a class-weighted objective and a deeper classification head. The detector operates directly on the input image, retaining alternative piece hypotheses that are subsequently refined using constraints on piece counts and square occupancy. For board detection, we introduce an octagonal arrangement of eight labelled boundary keypoints, predicted using the keypoint head of Mask R-CNN. These provide redundant correspondences for homography estimation and encode board orientation. The estimated homography maps representative points from the piece boxes to an 8x8 grid. On a synthetic dataset, the modifications to piece detection increase mean average precision from 61.59% to 90.14%. Of the predicted board keypoints, 97.11% are within 1% of the image diagonal of their labelled targets. Using ground-truth piece boxes with the predicted homographies gives correct square assignments for every test position. The complete framework recovers 76.61% of test positions exactly and 96.49% with at most one incorrect square.

StableGrasp: Reconstructing Physically Stable Human Hand Grasps from Single Images

StableGrasp:从单幅图像重建物理稳定的人手抓握
Jiang, Han, Vouga, Etienne, Huang, Qixing, Pavlakos, Georgios
Abstract
Reconstructing a physically stable human grasp from a single RGB image is challenging because physically modeling grasps is itself difficult, and the problem requires estimating not only a visually constrained hand pose but also a control target that stabilizes the grasp. Existing methods either model only visual hand geometry without considering physics, or rely on less plausible physical modeling, which limits the physical validity of the resulting grasps. In this paper, we present StableGrasp, a differentiable simulation-based optimization framework that explicitly separates the visual hand pose from the control target that determines the grasping forces. Our method jointly optimizes hand geometry and control by minimizing the kinetic energy of the grasp in a differentiable simulator, while regularizing the hand geometry to preserve visual consistency and geometric plausibility. The reconstructed grasps are substantially more stable under rigorous physical simulation, while remaining visually consistent with the input images and geometrically plausible. Experiments show that our approach produces far more stable grasps than alternative hand-control strategies, benefiting visual-only grasp reconstruction pipelines by turning their outputs into physically stable grasps.

从单幅RGB图像重建物理稳定的人手抓握是一项挑战,因为物理建模抓握本身就很困难,并且该问题不仅需要估计视觉约束下的手部姿态,还需要确定一个控制目标以稳定抓握。现有方法要么仅建模视觉手部几何形状而不考虑物理因素,要么依赖于不太可信的物理建模,这限制了所得抓握的物理有效性。在本文中,我们提出了StableGrasp,一个基于可微分仿真的优化框架,明确将视觉手部姿态与决定抓握力的控制目标分开。我们的方法通过在可微分仿真器中最小化抓握的动能来联合优化手部几何形状和控制,同时对手部几何形状进行正则化,以保持视觉一致性和几何合理性。重建的抓握在严格的物理仿真下显著更稳定,同时与输入图像保持视觉一致性和几何合理性。实验表明,我们的方法产生的抓握比替代的手部控制策略稳定得多,能够使仅依赖视觉的抓握重建流程的输出转化为物理稳定的抓握。

StyleFields: Multi-Scale AdaIN-Modulated Implicit SDFs for Coarse-to-Fine 3D Shape Reconstruction and Editing

StyleFields:用于粗到细3D形状重建和编辑的多尺度AdaIN调制隐式SDF
Garaaghaji, Ehsan, Talabot, Nicolas, Fua, Pascal, Oner, Doruk
Abstract
We introduce StyleFields, a DeepSDF-based architecture for high-fidelity 3D reconstruction that enables controllable geometric style mixing: the coarse structure of one object can be combined with the fine-scale details of another. The core idea is depth-aware modulation: instead of a single global code, we inject latents via multi-level Adaptive Instance Normalization at several decoder depths, and supervise matching auxiliary heads with a coarse-to-fine schedule while gradually growing network depth. This aligns early layers with global shape and later layers with high-frequency detail, achieving content-style decoupling without part labels or adversarial training. StyleFields delivers faithful reconstructions, convincing cross-instance hybrids, and consistent gains in ablations over injection depth and supervision granularity. We further demonstrate a practical application in automotive aerodynamics: a learned surrogate drag predictor serves as a differentiable objective to optimize reconstructed cars, allowing targeted edits of global form or surface details by freezing the complementary latent stream. StyleFields offers a simple, effective recipe for controllable implicit reconstruction and downstream performance-driven design.

我们介绍了StyleFields,这是一种基于DeepSDF的高保真3D重建架构,能够实现可控的几何风格混合:一个物体的粗略结构可以与另一个物体的细节相结合。其核心思想是深度感知调制:我们通过在多个解码器深度上使用多级自适应实例归一化(Adaptive Instance Normalization)注入潜在变量,而不是使用单一的全局编码,并在逐渐增加网络深度的同时,监督匹配辅助头部,采用粗到细的调度。这使得早期层与全局形状对齐,而后期层与高频细节对齐,实现了内容与风格的解耦,而无需部件标签或对抗训练。StyleFields提供了真实的重建、令人信服的跨实例混合,并在注入深度和监督粒度的消融实验中取得了一致的提升。我们进一步展示了在汽车空气动力学中的实际应用:学习到的替代阻力预测器作为可微分目标,优化重建的汽车,允许通过冻结互补潜在流来有针对性地编辑全局形状或表面细节。StyleFields为可控的隐式重建和下游性能驱动设计提供了一种简单有效的方法。

Do Vision Models Learn Physical Constraints or Rendering Shortcuts? A Counterfactual Benchmark for Grounded Physical Consistency

视觉模型是学习物理约束还是渲染捷径?一个关于基础物理一致性的反事实基准
Esfahani, M. Moein, Salem, Sepehr, Alser, Mohammed, Calhoun, Vince
Abstract
Modern image editing models can satisfy a text instruction while breaking the physics of the edited scene. A new object may cast no shadow, a mirror may fail to reflect visible geometry, or an object may float above a surface that should support it. We study physical plausibility diagnosis, detecting whether an edited image violates scene physics, naming the violation type, localizing the affected region, and explaining the failure in language. We introduce a counterfactual benchmark whose controlled synthetic component uses Mitsuba~3 to generate 5,500 images from 500 scene families. Each family contains one clean image and ten matched violations involving shadows, reflection, support, surface response, and occlusion. The renderer pipeline provides category labels, affected-region masks and boxes, scene metadata, and explanation targets. We use LLaVA-1.5-7B, Qwen2.5-VL-7B, and InternVL3.5-8B as diagnostic baselines rather than proposed methods. On a 1,650-image synthetic test set, the adapted baselines reach 64.0--67.8\% category macro-F1 on standard held-out scenes. For LLaVA-1.5-7B, category macro-F1 falls from 64.0\% on the standard split to 40.8\% under intervention shift. This gap shows that high in-distribution accuracy partly reflects cues tied to rendering and counterfactual construction.

A Deterministic Evidence Layer for Vision-Language Autism Screening from Naturalistic Home Video

基于自然家庭视频的视觉-语言自闭症筛查的确定性证据层
Li, Wenqi, Ruan, Mindi, Hu, Chuanbo, Wang, Shuo, Li, Xin
Abstract
Autism spectrum disorder (ASD) is diagnosed through specialist observation of a child's social behavior, and access to that expertise is the bottleneck for early identification. Vision-language models (VLMs) describe a child's behavior from video well; the verdict drawn from the description is unstable: at temperature~0, across eight pipeline configurations on one backbone, 16--37\% of clips change their predicted label between repeated runs, and the cause lies in the serving stack. We keep the VLM frozen and move the decision out of the model. Under our grounded perception constraints the VLM writes an event table of timestamped, glossary-labeled events that names the eliciting press and logs counter-evidence; a text-only stage age-calibrates the confidence of each row; a deterministic weight-of-evidence scorer sums it into an evidence total and stratifies it into a risk category, so every decision decomposes into named per-feature contributions and can be re-scored from the saved table. On 43 caregiver-recorded, protocol-free home free-play clips of preschool children, the pipeline reaches AUC $0.851 \pm 0.012$, 86.0\% accuracy, and F$_1$ 71.8 over three runs. It labels 74.4\% of clips correctly in every run (60.5\% for the zero-shot baseline) and flags no typically developing clip in every run (9 of 31 at zero-shot). An ablation on the same backbone attributes the gain to the grounded perception constraints read through the deterministic scorer.

PVSync: A Unified Lip-Sync Expert for Timing and Articulation

Abstract
Lip movements can match the timing of speech without matching the spoken sounds. We introduce PVSync, a unified model for audio-visual offset estimation and phoneme-level articulation scoring. PVSync combines window-level contrastive learning for synchronisation with a phoneme-level articulation objective that aligns audio and video embeddings of the same viseme class across clips. Visemes group phonemes with similar visible articulation. Viseme labels are derived automatically from forced-aligned transcripts, without manual annotations. On offset-corrected videos from 13 talking-head video generation models, PVSync matches human rankings of lip-sync quality more closely than LSE-C, achieving a Spearman correlation of 0.83 versus 0.34. On an automatically constructed benchmark from held-out speech, PVSync distinguishes viseme-matched from mismatched audio-visual pairs with an ROC AUC of 0.91. PVSync also outperforms SyncNet and MTD-VocaLiST in temporal offset recovery on held-out in-the-wild clips. Code and benchmark data will be released upon acceptance.

Abstract
Representation Autoencoders (RAEs) generate images from pre-trained visual fea- tures, but their dense token grids make generative modeling expensive. Motivated by local feature correlations, we introduce PoolDINO, a learned affine pooling operator that merges neighboring tokens. Training the pooling operator jointly with the RGB decoder preserves the standard two-stage RAE procedure without a separate feature auto-encoder. On ImageNet-256, 4x token compression retains comparable generation quality under internal guidance, while 16x compression trades some quality for greater efficiency. At a fixed budget of 100 sampling steps, latent-sampling throughput increases by 3.7x and 9.0x, respectively, relative to the unpooled baseline. Classification and dense prediction evaluations show that comparable guided generation quality can coexist with weaker performance on other tasks.

表示自编码器(Representation Autoencoders, RAEs)从预训练的视觉特征生成图像,但其密集的标记网格使得生成建模成本高昂。基于局部特征相关性的动机,我们引入了PoolDINO,一种学习的仿射池化算子,用于合并相邻的标记。与RGB解码器共同训练池化算子,保留了标准的两阶段RAE过程,而无需单独的特征自编码器。在ImageNet-256上,4倍的标记压缩在内部指导下保持了可比的生成质量,而16倍压缩则在提高效率的同时牺牲了一定的质量。在固定的100次采样步骤预算下,相较于未池化的基线,潜在采样的吞吐量分别提高了3.7倍和9.0倍。分类和密集预测评估表明,可比的指导生成质量可以与其他任务的较弱性能共存。

Adaptive Visual Token Reduction for Accelerated Image Understanding

自适应视觉标记减少以加速图像理解
Jeong, Seyoung, Yun, Jong Pil, Lee, Sang Jun
Abstract
Large Vision-Language Models achieve strong VQA performance, but processing high-resolution, information-rich images requires substantial computation, motivating visual token reduction. However, existing methods often prune individual tokens or rely on fixed-size cropping, limiting their ability to preserve spatially structured information such as horizontally or vertically elongated text. To address this limitation, we propose ReFIT, an instruction-guided visual token reduction framework for efficient LVLM inference. ReFIT consists of Relevance-Guided Window Reshaping (RWR) and Instruction-Guided Token Refinement (ITR), where RWR captures instruction-relevant regions by adapting to their spatial characteristics, while ITR further removes unnecessary visual tokens. Experiments on four VQA benchmarks demonstrate that ReFIT improves answer accuracy while reducing computational cost, and qualitative results demonstrate its effectiveness in localizing relevant regions and removing unnecessary visual information.

大型视觉-语言模型在视觉问答(VQA)任务中表现出色,但处理高分辨率、信息丰富的图像需要大量计算,这促使了视觉标记的减少。然而,现有方法通常仅修剪单个标记或依赖固定大小的裁剪,限制了它们保留空间结构信息(如水平或垂直延伸的文本)的能力。为了解决这一局限性,我们提出了ReFIT,一个基于指令的视觉标记减少框架,用于高效的LVLM推理。ReFIT由相关性引导的窗口重塑(RWR)和指令引导的标记精炼(ITR)组成,其中RWR通过适应空间特征捕获与指令相关的区域,而ITR进一步去除不必要的视觉标记。在四个VQA基准上的实验表明,ReFIT在提高答案准确性的同时降低了计算成本,定性结果展示了其在定位相关区域和去除不必要视觉信息方面的有效性。

PhyDiCT: Plug-and-Play CT Reconstruction from Sparse X-Rays via Differentiable Rendering and Strong Priors

PhyDiCT:基于可微渲染和强先验的稀疏X射线即插即用CT重建
Dai, Weicheng, Ghosh, Shantanu, Batmanghelich, Kayhan
Abstract
Reconstructing 3D Computed Tomography (CT) images from a few X-ray projections is a highly ill-posed inverse problem due to the loss of volumetric information. We propose PhyDiCT, a training-free framework that integrates a differentiable Physics-based forward model, grounded in the Beer-Lambert law, with a text-conditioned Diffusion as a strong prior to reconstruct 3D lung CT images. We refer to our approach as training-free since the prior model is used without fine-tuning, and our goal is to steer the denoising procedure to generate samples consistent with X-ray observations. We guide the diffusion generation using Split Gibbs sampling to jointly optimize for projection fidelity (reward) and consistency with prior knowledge. Also, we introduce a test-time refinement step that enhances image realism and anatomical coherence. We extensively evaluate our method on publicly available 3D CT datasets using both perceptual and semantic metrics, demonstrating that it surpasses existing plug-and-play diffusion and fully trained reconstruction approaches. Our findings highlight that combining a strong generative prior with the underlying physics of image formation substantially improves reconstruction quality, e.g., 7.5\% improvement on SSIM compared to full training methods. Code will be released at https://github.com/batmanlab/PhyDiCT.

Hardware-aware Calibrated Clustered Attention for Efficient Visual Geometric Transformers

硬件感知的校准聚类注意力机制用于高效的视觉几何变换器
Wang, Weitian, Rai, Shubham, De La Parra, Cecilia, Kumar, Akash
Abstract
The Visual Geometry Grounded Transformer (VGGT) marks a significant leap forward in 3D scene reconstruction, as it is the first model that directly infers all key 3D attributes (camera poses, depths, and dense geometry) jointly in one pass. However, this joint inference mechanism requires global attention layers with extremely long sequences that causes a significant latency bottleneck. In this paper, we propose blockwise clustered attention (BC attention) to accelerate the global attention layers in VGGT. By limiting the clustering within HW-friendly neighborhood blocks, BC attention reduces the computation overhead of query clustering as well as the costly data movement between on- and off-chip memory. This enables BC attention to scale to long sequences and deliver practical latency improvements on GPUs. Moreover, we introduce a hashing hyperplane calibration method and a threshold-based error compensation method to reduce clustering errors efficiently, which is a bottleneck in the current clustered attention mechanism. Overall, our experiments on GPU demonstrate that calibrated BC attention accelerates the global attention layers by 2.10-2.63$\times$ and the whole backbone by 1.77-2.35$\times$ with negligible loss (1%) for large scenes. With a small performance loss (< 5%), calibrated BC attention further achieves a 2.26-2.87$\times$ latency improvement on the global attention layers and a 1.90-2.55$\times$ improvement on the backbone.

视觉几何基础变换器(VGGT)标志着3D场景重建的重大进展,因为它是第一个在一次推理中直接联合推断所有关键3D属性(相机姿态、深度和稠密几何)的模型。然而,这种联合推理机制需要具有极长序列的全局注意力层,这导致了显著的延迟瓶颈。本文提出了一种块状聚类注意力机制(BC attention),旨在加速VGGT中的全局注意力层。通过限制聚类在硬件友好的邻域块内,BC attention减少了查询聚类的计算开销以及芯片内外存储之间昂贵的数据移动。这使得BC attention能够扩展到长序列,并在GPU上实现实际的延迟改进。此外,我们引入了一种哈希超平面校准方法和基于阈值的误差补偿方法,以有效减少聚类误差,这是当前聚类注意力机制中的一个瓶颈。总体而言,我们在GPU上的实验表明,校准的BC attention使全局注意力层加速了2.10-2.63倍,整个主干网络加速了1.77-2.35倍,且对大场景的损失微乎其微(1%)。在小幅性能损失(< 5%)的情况下,校准的BC attention在全局注意力层上进一步实现了2.26-2.87倍的延迟改进,并在主干网络上实现了1.90-2.55倍的改进。

EM-SNN: Efficiently Modulated Spiking Neural Network for Remote Sensing Image Dehazing

EM-SNN:用于遥感图像去雾的高效调制脉冲神经网络
Shao, Jie, Ma, Jiaqi, Min, Wenwen, Song, Beihang, Chen, Ning, Liu, Youfa, Wan, Jun
Abstract
Although spiking neural networks (SNNs) provide an energy-efficient alternative to artificial neural networks (ANNs), their application to remote sensing image dehazing remains limited. A key challenge arises from the coupling between haze-induced high-frequency attenuation and discrete spike thresholding. This interaction suppresses weak responses and fundamentally limits the recovery of edges, textures, and fine details in spiking dehazing models. To address this challenge, we propose the Efficiently Modulated Spiking Neural Network (EM-SNN), a dedicated spiking framework tailored to remote sensing image dehazing. EM-SNN integrates a statistics-driven Threshold-Modulated Leaky Integrate-and-Fire (TM-LIF) neuron to adaptively compensate for haze-induced contrast compression, together with a Spike Sobel Modulation (SSM) module that enhances structural cues and reduces depth-wise attenuation during spiking feature propagation. By jointly modulating activation scales and structural representations, EM-SNN improves dehazing performance while preserving the inherent event-driven sparsity of SNNs. Experiments on HRSD, RICE, RRSHID, and SateHaze1K demonstrate that EM-SNN achieves competitive dehazing performance while consuming only one quarter of the energy of the strong ANN baseline SFRDP-Net.

尽管脉冲神经网络(SNNs)提供了一个能量高效的替代方案来替代人工神经网络(ANNs),但其在遥感图像去雾中的应用仍然有限。一个主要挑战源于雾霾引起的高频衰减与离散脉冲阈值之间的耦合。这种相互作用抑制了微弱响应,并从根本上限制了脉冲去雾模型中边缘、纹理和细节的恢复。为了解决这一挑战,我们提出了高效调制脉冲神经网络(EM-SNN),这是一个专门为遥感图像去雾量身定制的脉冲框架。EM-SNN集成了一个基于统计的阈值调制泄漏积分发射(TM-LIF)神经元,以自适应地补偿雾霾引起的对比度压缩,并结合一个脉冲索贝尔调制(SSM)模块,增强结构线索并减少在脉冲特征传播过程中的深度衰减。通过共同调制激活尺度和结构表示,EM-SNN在提高去雾性能的同时,保持了SNNs固有的事件驱动稀疏性。在HRSD、RICE、RRSHID和SateHaze1K上的实验表明,EM-SNN在去雾性能上具有竞争力,同时仅消耗强ANN基线SFRDP-Net能量的四分之一。

Why VLMs Miss Small Objects, and When Zooming In Is Safe

为何视觉语言模型错过小物体,以及何时放大是安全的
Shi, Junzhe, Gan, Yuan, Jiang, Shida
Abstract
Vision-language models (VLMs) often miss small objects in large images. We ask three questions: what limits them, which of these limits better models can remove, and whether the classical way of handling large images, local decomposition, still has a future. We answer them with a theory built on two quantities of the image interface: S, the number of visual tokens across an object's side, and L, the content a call must cover. The limits: a W x H image sent whole within N tokens gives an object of side m at most m*sqrt(N/(WH)) tokens per side. Doubling the token budget N therefore raises the largest S a whole image can reach by only 41%, and seeing an image at the S an object needs costs at least order S^2 tokens whatever the model. If recognition improves gradually with S, any search strategy, zoom agents included, obeys a recall-cost frontier. What better models can change: the S an object needs and how much one call can carry, measured in bits per object found; the coverage cost remains. Decomposition: yes. Assuming only that more tokens per object and less content per call do not hurt on average, splitting an image cannot lower recall if no view zooms out relative to the whole image and views overlap by one object. Neither part of this condition can be dropped; we bound the cost of every such decomposition, and a simple rule approaches the bound as the image grows. We test the theory in about 177,000 requests on 797 images. On controlled images, none of 40 orderings predicted for 8 VLMs is violated. Checked after the fact on drawings, floor plans, natural and synthetic images, 61 of 89 implied orderings hold significantly and 4 fail, all for OpenAI models given more pixels than their default path. On construction drawings the rule never significantly lowered recall relative to the whole image and raised it by up to 0.28. Code and data: https://github.com/shijunzhe/vlm-small-objects

视觉语言模型(VLMs)在处理大图像时常常会错过小物体。我们提出了三个问题:是什么限制了它们,这些限制中哪些可以通过更好的模型去除,以及传统的处理大图像的方法——局部分解,是否仍然有未来。我们通过建立在图像接口的两个量(S,物体边缘的视觉标记数量;L,一个调用必须覆盖的内容)上的理论来回答这些问题。限制条件是:一个 W x H 的图像在 N 个标记内整体发送时,最多只能为边长为 m 的物体提供 m*sqrt(N/(WH)) 个标记。因而,增加标记预算 N 仅能使整个图像能够达到的最大 S 增加41%,而在任何模型下,看到一个物体所需的 S 的图像至少需要 S^2 个标记。如果识别随着 S 的增加而逐渐改善,那么任何搜索策略,包括放大代理,都遵循一个召回-成本边界。更好的模型可以改变的内容包括:物体所需的 S 以及一个调用能承载的内容量(以每个找到的物体的比特数衡量);覆盖成本保持不变。局部分解:是的。假设每个物体的标记数量增加而每个调用的内容减少在平均上不会造成损害,只要没有视图相对于整个图像缩小且视图之间重叠一个物体,分割图像不会降低召回率;该条件的任一部分都不能被省略;我们对每种分解的成本进行了界定,且随着图像的增长,一个简单的规则接近该界限。我们在约177,000个请求和797幅图像上测试了该理论。在受控图像上,40种针对8个VLMs的排序预测没有被违反。经过事后检查,在图纸、平面图、自然和合成图像中,89个隐含排序中有61个显著成立,4个失败,所有失败均为OpenAI模型在给定比其默认路径更多像素时出现。在施工图上,该规则相对于整个图像从未显著降低召回率,且最多提高了0.28。代码和数据: https://github.com/shijunzhe/vlm-small-objects

SAREO-FM: Decoupled Semantic Supervision for SAR-EO Foundation Models

SAREO-FM:用于SAR-EO基础模型的解耦语义监督
Do, Jeonghyeok, Kim, Munchurl
Abstract
Synthetic aperture radar (SAR) and electro-optical (EO) imagery provide complementary observations: SAR enables day-and-night, weather-resilient sensing, whereas EO provides rich appearance and fine-grained semantic cues. We introduce SAREO-FM, which avoids forcing a single token stream to serve two distinct roles: modality tokens preserve how each sensor observes the scene through masked reconstruction, while learnable semantic queries capture what the scene contains under guidance from a pretrained vision foundation model (VFM). By jointly encoding these queries with SAR and EO tokens, the queries acquire modality-grounded semantic context, while the modality-token outputs remain the explicit targets of masked reconstruction. This design assigns semantic and reconstruction supervision to separate token streams while preserving their interaction within the shared encoder. Pretrained on the million-scale SAR-1M corpus, SAREO-FM achieves strong unimodal transfer for both SAR-only and EO-only inputs, while delivering substantial gains from joint SAR--EO observations on tasks that benefit from complementary sensing.

合成孔径雷达(SAR)和电光(EO)图像提供了互补的观测:SAR能够在昼夜和恶劣天气条件下进行感知,而EO则提供丰富的外观和细粒度的语义线索。我们提出了SAREO-FM,它避免了强迫单一的标记流承担两个不同的角色:模态标记通过掩码重建保留了每个传感器如何观察场景,而可学习的语义查询在预训练的视觉基础模型(VFM)的指导下捕捉场景所包含的内容。通过将这些查询与SAR和EO标记共同编码,查询获得了基于模态的语义上下文,而模态标记的输出仍然是掩码重建的明确目标。这一设计将语义和重建监督分配给不同的标记流,同时保留它们在共享编码器中的交互。在百万规模的SAR-1M语料库上进行预训练后,SAREO-FM在SAR单模态和EO单模态输入上实现了强大的单模态迁移,同时在受益于互补感知的任务中,从联合SAR-EO观测中获得了显著的提升。

VIS-Ground: Video Interactive Storytelling with Contextual Grounding

VIS-Ground:具有上下文基础的视频互动叙事
Li, Bingxuan, Song, Yiwen, Wu, Xueqing, Pan, Yanzhou, Li, Yang, Su, Kuang, Liu, Jingyun, Ko, Sebastian, Zhang, Huan, Zhang, Tong, Peng, Nanyun, Pfister, Tomas, Song, Yale
Abstract
Video interactive storytelling enables viewers to actively steer how a video unfolds. However, once we allow viewers to intervene during generation, a new challenge arises: The viewer's request can have latent dependencies on both the grounding source and the current rendered video state. These dependencies may not be explicitly stated in any individual input, but emerge only when the source, rendered history, and new viewer intent are considered jointly. Existing interactive video generation systems primarily emphasize following viewer instructions, while source-grounded video generation methods focus on aligning generated content with an external narrative or knowledge source. This leaves a fundamental question underexplored: What context should a generation model ground on during interactive continuation, and how can heterogeneous, unstructured inputs be transformed into such grounding context? In this work, we formulate contextual grounding as the process of transforming heterogeneous input context into an executable constraint model for video generation. To address this challenge, we introduce VIS-Ground, which performs Structured Context Abstraction to recover grounded states and cross-context dependencies, Generation Constraints Induction to project relevant dependencies into candidate-specific constraints, and Constrained Video Generation to enforce these constraints through planning, verification, revision, and rendering. Across three video generation backbones, VIS-Ground consistently achieves the highest overall composite score, reaching an average absolute improvement of 10.3 points over the strongest per-backbone baselines. Detailed analysis further shows gains across both narrative and knowledge grounding, and reveals remaining challenges in dependency extraction, and faithful realization during video rendering.

Visual Jev Rewards: Reference-Bound Verification for Multi-Subject Image Generation

视觉Jev奖励:多主体图像生成的参考边界验证
Li, Baoteng, Wu, Wenzhuo, Liang, Kongming, Ma, Zhanyu
Abstract
Multi-subject image generation requires rewards that verify whether requested attributes, actions, and relations hold for the specified reference subjects. Subject presence alone does not establish that the correct subjects participate in a requested interaction. We present reference-bound Visual Jev rewards that turn these visual decisions into generator training signals. Each subject-related question receives a positive label only when the requested condition and the relevant reference identities hold jointly. We construct fixed questions offline, train a Qwen3.5-4B verifier with binary supervision, and directly read Yes probabilities from its language-model head. Their mean supplies a GRPO reward while retaining individual judgments for inspection. Using 200 MICo-150K training tasks and 30 updates, the framework raises a GPT-5.4 composite score from 41.78 to 52.50 on a manually selected 897-task MICo-Bench subset; direct 27B rewards yield 51.84. Each reward is tested in one GRPO run, and offline human evaluation does not establish a statistically significant advantage over direct scoring. The study provides an initial implementation and evaluation of Visual Jev as a reference-bound reward for multi-subject image generation.

GRC-Net: Global Representation Consistency Network for Unsupervised Multimodal Anomaly Detection

GRC-Net:用于无监督多模态异常检测的全局表示一致性网络
Jeong, Seyoung, Yun, Jong Pil, Lee, Sang Jun
Abstract
Automated quality inspection is essential for ensuring product reliability in manufacturing.While image-based methods effectively capture appearance-related defects, these methods are limited in detecting structural and geometric anomalies, motivating multimodal approaches incorporating 3D information. However, existing methods mainly rely on local patch-level representations, which often lead to unstable reconstruction errors even in normal regions. To address this limitation, we propose GRC-Net, which integrates a global-attention MLP to enforce global representation consistency across patch embeddings with a stable reconstruction module to improve reconstruction stability. The proposed method captures holistic contextual information through a global token and suppresses reconstruction noise by minimizing discrepancies between original and predicted embeddings. Experiments on MVTec 3D-AD and Eyecandies demonstrate that GRC-Net consistently outperforms existing methods at both image and pixel levels. Qualitative results further demonstrate reduced reconstruction errors in normal regions and more distinct reconstruction differences between normal and anomalous regions.

CRT-HMAR: Causal Requirement Tracing-Guided Hierarchical Multi-Agent Regulation for Open-Task-Aware Infrared-Visible Image Fusion

CRT-HMAR:基于因果需求追踪的分层多智能体调节框架用于开放任务感知的红外-可见图像融合
Yang, Zengyi, Yuan, Shuai, Wu, Zhong-Cheng, Cheng, Juan, Li, Huafeng, Liu, Yu
Abstract
Infrared and visible (IR-VIS) image fusion integrates complementary multimodal information into a single fused image to support downstream vision tasks. However, existing methods are typically tailored to seen tasks within a fixed task set and struggle to generalize to unseen tasks, which restricts their applicability in real-world open-task scenarios. To address this issue, this paper proposes CRT-HMAR, a Causal Requirement Tracing-Guided Hierarchical Multi-Agent Regulation Framework for open-task-aware IR-VIS image fusion. CRT-HMAR introduces a Causal Requirement Tracing Task Localization mechanism, which actively intervenes in key image information and observes task-network response variations to map task-specific semantic preferences into image-level causal requirement maps. Based on these maps, a requirement analysis agent aggregates task-specific requirement knowledge to adaptively guide requirement-customized image fusion. Moreover, CRT-HMAR incorporates History-Analysis Multi-Objective Balancing and Task-Level-Correction Conflict Mitigation mechanisms, jointly constructing a hierarchical regulation chain of "requirement interpretation - task balancing - conflict mitigation". Through multiple collaborative agents, CRT-HMAR dynamically regulates key processes including open-task requirement modeling, multi-task balanced optimization, and gradient conflict mitigation. Extensive experiments on open-task scenarios involving five downstream tasks demonstrate that CRT-HMAR significantly improves generalization to unseen tasks while maintaining the performance and balance of seen tasks. Overall, CRT-HMAR shifts IR-VIS image fusion from task-oriented modeling toward requirement-oriented modeling, promoting its extension from closed-task settings to real-world open-task scenarios.

TileSkipper: Region-Adaptive Tile Pruning for 3D Gaussian Splatting

TileSkipper:区域自适应瓷砖修剪用于3D高斯点云渲染
Li, Jingxing, Lee, Yongjae, Fan, Deliang, Yadav, Abhay Kumar, Peng, Cheng, Chellappa, Rama
Abstract
Tiled 3D Gaussian Splatting rasterizers often use one scene-wide contribution cutoff for tile enumeration, although content differs in its sensitivity to support truncation. TileSkipper selects a static per-Gaussian cutoff policy for a frozen checkpoint. Calibration renders measure candidate pair savings and an isolated-removal distortion proxy that accounts for front transmittance and background color. The method allocates cutoffs across 64 Gaussian groups and accepts policies only after complete renders on disjoint selection views. The exported policy uses one byte per Gaussian, with no parameter updates, additional kernel, or per-frame policy inference. Across 13 scenes from Mip-NeRF 360, Tanks & Temples, and Deep Blending, a fixed-policy AccuTile sweep gives dataset-macro speedups of $1.088\times$ at standard resolution and $1.238\times$ at 3840 pixels wide, with $-0.007/-0.023$ dB mean PSNR change. Six integrations with existing opacity-aware bounds yield $1.009\times$--$1.121\times$ compiler-only speedups. For four ports from $3\sigma$ rasterizers, we separately attribute the prior exact-bound transition and our incremental gain. Matched-quality ablations show modest gains over scene-global calibration and parity with per-Gaussian control; the standalone comparison with AdaGScale is regime-dependent.

Do Image Editors Follow Depth-Dependent Blur and Aperture Response? A Rendered-Ground-Truth Pilot Audit

图像编辑器是否遵循深度依赖模糊和光圈响应?一项渲染真实情况的初步审计
Chen, Zhihan, Zhao, Yuhuan, Zhu, Yijie, Yao, Xinyu, Ren, Mengcong, Sun, Yuchen, Chen, Yunqing
Abstract
General image editors are asked to make a photo look as if it were taken at f/1.4, yet it is rarely checked whether the blur they add follows thin-lens optics. A physical aperture edit spreads blur across depth in thin-lens proportions and changes the blur when the aperture changes; prior evaluations check blur monotonicity, sharpness-trend correlation, effective-aperture error, or vision-language judgments, and none we found reports the two properties separately at known depths. In this pilot audit of two editors (Gemini~3.1 Flash Image and GPT-image-2.5) we compare against a rendered oracle: Blender Cycles scenes with true thin-lens depth of field, one blur-width estimator applied identically to oracle and editor outputs, and preregistered depth and aperture indices. In 24 texture scenes rendered in one three-panel geometry, accepted and measurable panels show f/1.4-to-f/2.8 width ratios, $\bar\sigma_{1.4}/\bar\sigma_{2.8}$, of 0.99--1.18 against 1.98--2.13 for the oracle, and ratios of pooled median Gaussian-equivalent near/far blur widths of about 1.18--1.25 (Gemini) and 0.97--1.05 (GPT-image) against 1.69--1.82. Preregistered black-box interventions show that qualitative wording changes blur strength by roughly 2--10 times, whereas a request for 2 versus 6 px changes it 1.1--1.3 times and no tested wording of the f-number meets the registered ``followed'' criterion. The depth compression appears in the original and reversed centre-focus layouts; with the focus on the near panel, the available-panel depth index reaches the registered threshold, and the aperture response stays attenuated in every layout tested. Scalar metrics adapted from published ones give oracle-like scores to synthetic editors whose proportions are compressed.

Closing the Loop on Contrail Avoidance with Satellite Verification

通过卫星验证关闭航迹避免的循环
Chowdhury, Spandan Ghose
Abstract
Contrails are the thin ice clouds that aircraft leave behind. They cause a large share of aviation's warming, and rerouting the few flights that produce them could avoid much of it. However, an avoided contrail only counts if a satellite can confirm that it never formed, and this check is hard: contrails are one to two pixels wide, cover only 0.18% of pixels, and look very similar to natural cirrus. We build a small diffusion model (8.4M parameters, trained on one GPU) that detects them, and we run a controlled study to find out which components matter. The model reaches 0.476 PR-AUC, compared with 0.414 for a DeepLabV3+ baseline and 0.119 for an adapted MedSegDiff. Doubling the input resolution of the CNN brings it to parity (0.499, p=0.07). Three lessons apply beyond contrails. First, check the input resolution before designing a new architecture. Second, simple flips and rotations more than double accuracy and matter more than any architectural choice we measured. Third, pretraining the model on contrail shapes is harmful: the model learns that thin strokes appear everywhere and paints them onto empty scenes. Precision collapses to 1% while recall-based metrics still rate the degraded model as excellent, and no threshold or guidance heuristic repairs this failure.

航迹是飞机留下的细冰云。它们在航空业的变暖中占据了很大一部分,重新规划少数产生航迹的航班可以避免大部分影响。然而,只有在卫星能够确认航迹确实没有形成时,避免的航迹才算有效,而这一检查非常困难:航迹宽度为一到两个像素,仅覆盖0.18%的像素,并且与自然卷云非常相似。我们构建了一个小型扩散模型(8.4M参数,在一台GPU上训练),用于检测航迹,并进行了一项控制研究以找出哪些组件是重要的。该模型的PR-AUC达到了0.476,而DeepLabV3+基线为0.414,调整后的MedSegDiff为0.119。将CNN的输入分辨率翻倍使其达到了平衡(0.499,p=0.07)。有三个教训适用于航迹之外的情况。首先,在设计新架构之前检查输入分辨率。其次,简单的翻转和旋转使准确率翻倍,且比我们测量的任何架构选择更为重要。第三,在航迹形状上对模型进行预训练是有害的:模型学习到细线条无处不在,并将其绘制到空白场景中。精确度降至1%,而基于召回的指标仍然将退化模型评为优秀,且没有任何阈值或指导启发式能够修复这一失败。

Unified Multi-plane Autoregressive Diffusion for 3D Multi-contrast MRI Synthesis

统一的多平面自回归扩散用于三维多对比度MRI合成
Shin, Yejee, Son, Geonhui, Wang, Jinglu, Jung, Minwoo, Lu, Yan, Hwang, Dosik
Abstract
Acquiring a complete set of magnetic resonance imaging (MRI) contrasts is time-intensive and uncomfortable for patients, despite the diagnostic value of multi-contrast imaging. This motivates synthesizing missing contrasts from those already acquired, which is an inherently 3D problem requiring anatomical coherence across axial, sagittal, and coronal planes. However, fully 3D generative models are often impracti- cal under computational resources that scale cubically with volume size. We propose a unified Multi-Plane Autoregressive Diffusion (MPAD), a latent diffusion framework that achieves full-volume 3D synthesis using efficient plane-wise 2D operations while preserving volumetric coherence. A 3D autoencoder first compresses MRI scans into an isotropic 3D la- tent representation. A 2D diffusion model is then trained to reconstruct masked latent slices of the target contrast, conditioned on both source- contrast slices and unmasked target-contrast slices. During inference, we introduce plane-wise autoregressive synthesis with inter-plane priors. Slices are generated autoregressively in random order within one plane orientation to maintain intra-plane continuity, then propagated as con- ditioning priors to orthogonal plane orientations to enforce inter-plane consistency. Compared to 3D latent diffusion baselines, MPAD reduces training and inference FLOPs by 7x and 3x, respectively, while also lowering inference time and peak memory consumption. Experiments on multiple datasets demonstrate that MPAD achieves superior perfor- mance, generating high-fidelity 3D volumes and supporting one-to-many translation within a single unified model.

尽管多对比度成像具有重要的诊断价值,但获取完整的磁共振成像(MRI)对比度集既耗时又让患者感到不适。这促使我们从已获取的对比度中合成缺失的对比度,这本质上是一个三维问题,需要在轴向、矢状面和冠状面之间保持解剖一致性。然而,完全的三维生成模型在计算资源上往往不切实际,因为其计算复杂度与体积大小的立方成正比。我们提出了一种统一的多平面自回归扩散(Multi-Plane Autoregressive Diffusion, MPAD)框架,这是一种潜在扩散框架,通过高效的平面级二维操作实现全体积三维合成,同时保持体积一致性。首先,三维自编码器将MRI扫描压缩为各向同性的三维潜在表示。然后,训练一个二维扩散模型以重建目标对比度的掩蔽潜在切片,条件是源对比度切片和未掩蔽的目标对比度切片。在推理过程中,我们引入了平面级自回归合成和跨平面先验。切片在一个平面方向内以随机顺序自回归生成,以保持平面内连续性,然后作为条件先验传播到正交平面方向,以确保平面间一致性。与三维潜在扩散基线相比,MPAD在训练和推理的浮点运算次数(FLOPs)分别减少了7倍和3倍,同时降低了推理时间和峰值内存消耗。在多个数据集上的实验表明,MPAD实现了优越的性能,生成高保真度的三维体积,并支持在单一统一模型内的一对多转换。

PPCAR-Net: Projection-Refined Parametric 3D Coronary Artery Reconstruction from Sparse X-ray Angiographic Views

PPCAR-Net:基于投影精炼的稀疏X射线血管造影视图的参数化三维冠状动脉重建
Ren, Yu, Lee, Hwee Kuan, Cham, Tat-Jen, Yap, Jonathan, Yeo, Khung Keong
Abstract
Sparse-view 3D coronary reconstruction commonly relies on cross-view correspondence and triangulation, which are vulnerable to vessel overlap and foreshortening, or on volumetric prediction followed by vascular-graph extraction, which does not directly provide centrelines and radii. We introduce PPCAR-Net, a projection-refined parametric coronary artery reconstruction network that directly predicts a branch-structured centreline-and-radius representation without explicit point matching, triangulation, or an intermediate volume. Given a variable number of segmented views, a coarse predictor combines frozen VGGT features with learned branch queries to estimate branch presence, B-spline centreline trajectories, and dense radius profiles. Projection-guided geometry and radius refiners then sample local evidence from the input views and apply residual corrections learned with 3D supervision. We evaluate representation fidelity and sparse-view reconstruction quantitatively and qualitatively. On simulated angiographic masks generated from CT-derived coronary anatomy, PPCAR-Net produces better connected artery reconstructions and achieves strong centreline accuracy, particularly for RCA, while maintaining competitive volumetric overlap. Coarse-to-fine inference takes 121 ms, enabling real-time reconstruction.

Quantifying Volumetric Risk: Class-Aware Asymmetric Weighted Conformal Prediction for 3D Medical Image Segmentation

量化体积风险:面向类别的非对称加权保形预测在3D医学图像分割中的应用
Alijani, Shadi, Meibodi, Fereshteh Aghaee, Najjaran, Homayoun
Abstract
Reliable volumetric segmentation is critical for clinical diagnostics, yet foundation models such as MedSAM remain deterministic and lack calibrated uncertainty under distribution shift. Existing conformal prediction methods offer statistical guarantees but are frequently applied in 2D and assume symmetric error distributions, so they do not capture the class-specific biases that arise in 3D multi-class segmentation. We propose Class-Aware Asymmetric Weighted Conformal Prediction (CA-WCP), which combines latent-space density-ratio weighting for covariate shift with directional quantiles for the lower and upper volume bounds, and scales each bound by a class-specific asymmetry factor derived from validation-set false-positive and false-negative rates. We prove that CA-WCP retains the weighted-exchangeability marginal coverage guarantee for every class, and we evaluate it on 3D brain tumor segmentation (BraTS 2020) and on a synthetic multi-organ CT benchmark constructed under covariate shift. On both benchmarks the 95\% Clopper--Pearson interval for the observed coverage of CA-WCP contains the nominal 90\% level for every semantic class, while interval width is reduced by 8--14\% relative to symmetric weighted conformal prediction. We further encode the calibrated intervals into structured prompts for a multimodal large language model to produce uncertainty-conditioned radiology reports, linking distribution-shift-aware uncertainty quantification to interpretable clinical communication.

可靠的体积分割对于临床诊断至关重要,但像MedSAM这样的基础模型仍然是确定性的,并且在分布变化下缺乏校准的不确定性。现有的保形预测方法提供了统计保证,但通常应用于2D,并假设误差分布是对称的,因此无法捕捉在3D多类别分割中出现的类别特定偏差。我们提出了面向类别的非对称加权保形预测(Class-Aware Asymmetric Weighted Conformal Prediction,CA-WCP),该方法结合了潜在空间密度比加权以应对协变量变化,并使用方向性分位数来确定下限和上限体积边界,并通过从验证集的假阳性和假阴性率中导出的类别特定非对称因子来缩放每个边界。我们证明了CA-WCP为每个类别保留了加权可交换边际覆盖保证,并在3D脑肿瘤分割(BraTS 2020)和在协变量变化下构建的合成多脏器CT基准上进行了评估。在这两个基准上,CA-WCP的观察覆盖的95% Clopper--Pearson区间包含每个语义类别的名义90%水平,同时相对于对称加权保形预测,区间宽度减少了8%至14%。我们进一步将校准区间编码为结构化提示,以便多模态大型语言模型生成不确定性条件的放射学报告,将分布变化感知的不确定性量化与可解释的临床沟通联系起来。

One Frame, Full Heartbeat: ECG-Free Cardiac Cine MRI Synthesis via Phase-Conditioned Flow Matching

单帧,全心跳:通过相位条件流匹配实现无心电图的心脏电影磁共振成像合成
Wang, Shiyi, Sun, Ruochen, Liu, Peirong, Li, Xiang, Xing, Fangxu
Abstract
Cine cardiovascular magnetic resonance (CMR) analysis relies on multi-frame sequences capturing the full cardiac cycle. However, standard multi-frame acquisition depends heavily on electrocardiogram (ECG) gating and repeated breath-holds, posing challenges in uncooperative populations, resource-limited settings, and temporally corrupted datasets. Existing methods that synthesize full cardiac sequences either rely on explicit ECG signals to parameterize myocardium function, or employ deformable registration without physiological constraints, failing to faithfully reproduce clinically relevant dynamic metrics such as ejection fraction (EF) and ventricular contraction magnitude. We present PhaseFlow, a unified generative framework that overcomes both limitations. PhaseFlow estimates a non-linear cardiac phase signal directly from the input sequence via a segmentation-derived left-ventricular (LV) area curve, capturing the asymmetric dynamics of systole and diastole without any ECG dependency. At inference, this phase signal is provided by a pathology-specific template, informing phase-specific frame generation. A rectified flow model conditioned on the phase and slice position synthesizes the full cardiac motion trajectory in the latent space, decoded into a diffeomorphic displacement field that warps end-diastole pixel intensities directly, eliminating the reconstruction blur often accompanying the variational autoencoder. On the ACDC benchmark, PhaseFlow achieves superior physiological fidelity and image realism, with best LV volume curve $R^2$, structural similarity (SSIM) and generative quality (FID) among all baselines. Ablation studies confirm that each proposed component contributes measurably to the overall performance.

TiTok: Audio-Visual LLM for Multi-Segment Temporal Grounding

TiTok:用于多段时间定位的音视频大语言模型
Shin, Eunji, Choi, Dahyun, Jo, Seungyeon, Hong, Yejin, Lee, Jiyoung
Abstract
Audio-visual multi-segment grounding (AV-MSG) in untrimmed videos, reasoning over audio-visual evidence and predicting multiple segments for a query, is a fundamental problem but remains challenging. Visual-only models overlook complementary acoustic cues, while audio-visual models often fail to calibrate the number of events - a phenomenon we refer to as count miscalibration. We present TiTok, an audio-visual large language model (AV-LLM) that localizes an arbitrary number of temporal event segments for each query. For precise boundary prediction, we introduce the Time Token Interleaving (TTI) method, which explicitly injects special time tokens into the audio-visual stream to align input-side temporal perception with output-side temporal prediction. We further propose decoupled, multi-segment-oriented rewards for reinforcement learning, consisting of global, local, count, precision, and format rewards, optimized with Group reward-Decoupled Normalization Policy Optimization (GDPO). To assess the performance on AV-MSG, we establish a new UnAV-100-based evaluation protocol, and propose the CountF1 metric for quantifying count miscalibration that overlap metrics fail to capture. TiTok reaches 65.7 mIoU and 0.58 CountF1, achieving state-of-the-art performance. Our code is available at this link.

Abstract
Effective remote monitoring and surveillance using drones are frequently impeded by severe environmental and thermal clutter, dynamic vegetation, target camouflage, and system latency. Drawing inspiration from the hunting strategies of birds of prey that hover and stabilize their vision to isolate subtle ground motion, we introduce trACT (temporal revelation Airborne Camera Trap), a lightweight, real-time aerial robotics framework designed for autonomous consumer drones. The system integrates Temporal Max Pooling (TMP), a low-level signal processing method that transforms imperceptible movement across a rolling integration window into robust value and time encodings, with self-supervised motion anomaly detection to isolate target motion from background environmental motion caused by wind gusts and drone drift. To overcome mechanical and processing delays, trACT combines motion prediction with automated gimbal-stabilized optical zoom verification and equitable multi-target verification balancing. Extensive real-world field experiments in densely forested wildlife habitats and surveillance scenarios demonstrate that trACT successfully bridges the gap between wide-area aerial monitoring and precise, autonomous target verification under challenging operational conditions.

Spatial Latent Reasoning for Embodied Reference Understanding

用于体现参考理解的空间潜在推理
Li, Ling, Zhong, Jianhui, Liu, Wei, Liu, Zheng Jiang aand Yuxuan, Li, Jingyu, Deng, Zhidong
Abstract
Pointing-gesture visual grounding requires connecting hand geometry with the visual identity and extent of a referred object. A central challenge for continuous latent reasoning is how to organize these complementary cues into useful intermediate supervision. We propose Spatial Latent Reasoning (SLR), a framework that structures this supervision around an ordered sequence of geometric and visual states. A spatial ray state is supervised by fingertip position and pointing direction, followed by four states aligned with target-region features. To construct the visual targets, we introduce parity pooling, which applies polyphase grouping to average region tokens on four interleaved spatial supports. All states are generated recurrently during training and inference; auxiliary annotations are required only during training. On EgoPoint-Ground, the framework improves mIoU over same-backbone supervised fine-tuning by 2.8, 17.5, and 21.1 percentage points on Qwen3.5-4B, Qwen2.5-VL-7B, and Qwen3-VL-8B, respectively, with improvements on both hard subsets. On YouRefIt, it achieves 77.6% precision at IoU 0.5, a numerical margin of 5.2 percentage points over the reported state of the art under differing evaluation protocols. Ablations support joint geometric and visual supervision on the standard and similar-object sets, and favor parity over three alternative pooling operators on the standard set. These results support task-structured supervision for continuous pointing grounding. We will release the code and supporting materials.

Event-Aligned Visual Action Reasoning for World Action Models

事件对齐的视觉行动推理用于世界行动模型
Yang, Xiaomeng, Wu, Yushu, Gao, Yi, Lei, Yuhao, Zhang, Xuan, Zhao, Pu, Wang, Yanzhi
Abstract
World-Action Models (WAMs) utilize future visual prediction as an intermediate reasoning process to guide action generation. However, existing WAMs typically structure visual imagination according to predefined temporal intervals, without explicitly accounting for the different roles of task-critical interactions and connecting transitions. We argue that effective visual foresight should align directly with task-relevant interactions and their corresponding reasoning demands. To this end, we introduce an event-aligned visual action reasoning framework that organizes visual-action prediction around interaction events. Through event-aligned visual-action supervision, WAM learns to generate event-aligned visual context in each imagined rollout, placing greater emphasis on critical state changes that inform action generation. This shapes the visual reasoning granularity according to the underlying interaction dynamics, with detailed reasoning around task-critical events and coarser progression through connecting transitions. Furthermore, we introduce an execution validity head that identifies the valid portion of each predicted action sequence, avoiding redundant actions during chunked inference. Experiments demonstrate a 10.26 percentage point improvement in DOMINO success rate over baseline and competitive performance on RoboTwin 2.0. It also transfers from DOMINO Level 1 to Levels 2 and 3 without target-level adaptation.

SkillCycle: Co-Evolving Agent Policies and Skill Banks

技能循环:共同进化的智能体策略与技能库
Li, Ling, Shen, Qiuyu, Jiang, Zheng, Ma, Qinwei, Liu, Yuxuan, Deng, Zhidong
Abstract
Internalizing external skills changes a language agent's capabilities and, with them, the value of its remaining guidance: rules can become redundant, misleading, or insufficient for newly encountered decisions. This creates a coupled problem of learning from skills and adapting the skills that supervise further learning. We introduce SkillCycle, a framework for co-evolving agent policies and skill banks through a feedback loop between skill internalization and rule revision. Our central contribution is to give distillation feedback a second role: token-level contextual differences help locate rules for inspection, while interaction outcomes guide edits to their content and applicability. SkillCycle alternates between two phases: policy learning with a fixed skill bank and router, and rule revision with a frozen policy. Candidate edits undergo rule-level and whole-bank environment comparisons before they guide the next learning cycle. On WebShop, SkillCycle with a 3B model achieves a success rate of 74.74% and a score of 88.37 without inference-time skill inputs, representing relative improvements of 0.73% and 3.96% over the state-of-the-art (SOTA) model, respectively. In Cycle 3 ablations on ALFWorld and WebShop, SkillCycle's no-skill success rates improve by 10.18% and 18.11% relative to a static skill bank, and by 2.41% and 2.50% relative to a single bank update, respectively. These results show that continually revising skill guidance as the agent's capabilities change helps transform external skills into policy capabilities that require no skill inputs at inference. We will release code, configurations, skill banks, and evaluation protocols.

Controllable Crowd Generation through World-Model Planning

通过世界模型规划实现可控人群生成
Lee, JunGyu, Shin, Jisu, Shin, Seunghyun, Jeon, Hae-Gon
Abstract
Crowd simulation plays a central role in robot navigation, autonomous driving, and urban planning. For these applications, realistic simulation requires crowds to adapt their behavior to environmental changes and user objectives. However, existing methods that rely on predefined control settings have limited flexibility in accommodating new user-specified objectives. To address this limitation, we propose Ctrl-CWM, a multi-agent Controllable Crowd World Model that integrates crowd generation and run-time control. Our key idea is to adapt the world-model principle of planning using imagined futures to crowd simulation. To this end, Ctrl-CWM consists of an encoder that learns a representation of human motion dynamics, an actor that proposes pedestrian displacements, a critic that evaluates imagined crowd trajectories, and a planner that selects actions. We first learn human motion dynamics through trajectory prediction on real-world pedestrian videos and then freeze the encoder to preserve them. Using this representation, the actor generates imagined crowd trajectories through repeated state updates, and the planner combines the critic's scores with user costs to select actions. Repeated planning advances the simulated crowd, while additional user costs introduce new control objectives without retraining. We extensively evaluate crowd generation under varied agent arrival conditions and run-time control across avoidance and attraction scenarios. Ctrl-CWM outperforms the state-of-the-art method on most crowd realism and collision metrics, and adapts crowd behaviors to user-specified objectives introduced during simulation.

人群模拟在机器人导航、自动驾驶和城市规划中发挥着核心作用。对于这些应用,现实的模拟要求人群能够根据环境变化和用户目标调整其行为。然而,现有依赖于预定义控制设置的方法在适应新的用户指定目标方面灵活性有限。为了解决这一局限性,我们提出了Ctrl-CWM,一个多智能体可控人群世界模型,集成人群生成和实时控制。我们的关键思想是将使用想象未来的世界模型规划原则应用于人群模拟。为此,Ctrl-CWM由一个学习人类运动动态表示的编码器、一个提出行人位移的执行者、一个评估想象人群轨迹的评论者和一个选择行动的规划者组成。我们首先通过对真实世界行人视频的轨迹预测学习人类运动动态,然后冻结编码器以保留这些动态。利用这一表示,执行者通过重复状态更新生成想象的人群轨迹,而规划者将评论者的评分与用户成本结合以选择行动。重复规划推动模拟人群的前进,而额外的用户成本在不重新训练的情况下引入新的控制目标。我们在不同的代理到达条件下广泛评估人群生成,并在避让和吸引场景中进行实时控制。Ctrl-CWM在大多数人群真实感和碰撞指标上优于现有最先进的方法,并能够将人群行为适应于模拟过程中引入的用户指定目标。项目页面可访问:https://jungyu0413.github.io/Ctrl-CWM

InscriptionOCR: A Dataset and Method for Understanding Inscriptions

InscriptionOCR:理解铭文的数据集和方法
Khalane, Jaidev Sanjay, Ali, Akbar, Prabhakar, V. N., Raman, Shanmuganathan
Abstract
Ancient script image restoration is a fundamental problem in computer vision, as it directly affects the reliable analysis and interpretation of historical documents and inscriptions. Ashokan Brahmi is an ancient script extensively used during the reign of Emperor Ashoka in the 3rd century BC, primarily for inscriptions in Prakrit. These inscriptions, including major and minor rock and pillar edicts, constitute a valuable yet largely unexplored source of data for computational analysis. The degraded nature of inscription imagery and the lack of standardized digital resources pose significant challenges for automated processing. We present an end-to-end AI-based framework for understanding ancient inscriptions that encompasses image enhancement, optical character recognition (OCR), transliteration, and neural machine translation (NMT). The proposed pipeline processes low-quality images captured directly from stone inscriptions, performs image restoration and Brahmi script character recognition, maps the recognized characters to the Roman script, and finally translates the resulting Prakrit text into English. We also introduce two new datasets: (i) InscriptionOCR Dataset: the largest publicly usable digital OCR dataset for Brahmi script to date, consisting of over 200,000 character images across about 600 classes, and (ii) a bilingual Prakrit-English parallel corpus comprising over 2,000 sentence pairs for NMT. We believe that the proposed framework and datasets will facilitate future research in ancient script analysis, low-resource OCR, and digital epigraphy.

古代文字图像修复是计算机视觉中的一个基本问题,因为它直接影响到历史文献和铭文的可靠分析与解读。阿育王梵文(Ashokan Brahmi)是一种古代文字,广泛使用于公元前3世纪阿育王统治时期,主要用于普拉克里特语(Prakrit)的铭文。这些铭文,包括主要和次要的岩石及柱子法令,构成了一个宝贵但尚未充分开发的计算分析数据源。铭文图像的退化特性以及缺乏标准化的数字资源为自动处理带来了重大挑战。我们提出了一个基于人工智能的端到端框架,用于理解古代铭文,该框架涵盖图像增强、光学字符识别(OCR)、音译和神经机器翻译(NMT)。所提议的流程处理直接从石刻铭文拍摄的低质量图像,进行图像修复和梵文字母识别,将识别出的字符映射到罗马字母,最后将生成的普拉克里特文本翻译成英语。我们还介绍了两个新的数据集:(i)InscriptionOCR 数据集:迄今为止最大的可公开使用的梵文字母数字OCR数据集,包含超过200,000个字符图像,涵盖约600个类别,以及(ii)一个双语普拉克里特语-英语平行语料库,包含超过2,000对句子用于NMT。我们相信,所提出的框架和数据集将促进未来在古代文字分析、低资源OCR和数字铭文学方面的研究。

Mixture of Layers: Dynamic Layer Routing for Visual Reasoning

层的混合:用于视觉推理的动态层路由
Kim, Jeonghwan, Stoica, Sofia, Chung, Jiwan, Blume, Ansel, Ha, Hyeonjeong, Wang, Zhenhailong, Dong, Xin Luna, Ji, Heng
Abstract
Pre-trained vision encoders contain layer-wise visual representations that differ in spatial granularity, semantic abstraction, and sensitivity to local details. However, most Multimodal Large Language Models (MLLMs) rely on only the final or penultimate vision encoder representations or fixed aggregation rules, making visual abstraction largely query-agnostic and limiting access to fine-grained cues such as small objects, spatial details, text, and subtle visual attributes. In this work, we propose Mixture of Layers (MoL), an instruction-conditioned layer routing approach at the visual patch level that dynamically aggregates query-relevant latent representations from intermediate vision encoder layers. Given a text query, MoL predicts routing probabilities over vision encoder layers and performs a top-k sparse aggregation over selected hidden states at either the image level, patch level, or through a hybrid routing mechanism. In doing so, MoL enables query-adaptive access to layer-specific visual features for fine-grained visual reasoning. Our experiments across 7 fine-grained visual reasoning tasks demonstrate substantial performance improvements, especially across fine-grained visual grounding and understanding tasks such as +18.9% improvement on V* in overall accuracy, +4.5% on HRBench4K, and +16.3% on CharXiv compared to the baseline MLLMs, without resorting to multi-resolution inputs, simple interleaving of multiple vision encoders, or increasing the number of patch tokens. We study vision encoders' receptive field scales across different layers and their sampling behaviors to provide an in-depth analysis of why layer-wise sampling is helpful, demonstrating that conditional visual representations are a key step towards better visual perception and reasoning in MLLMs. Our project page is available at https://wjdghks950.github.io/mol.github.io/.

预训练的视觉编码器包含在空间粒度、语义抽象和对局部细节敏感性方面各不相同的层级视觉表示。然而,大多数多模态大型语言模型(MLLMs)仅依赖于最终或倒数第二个视觉编码器的表示或固定的聚合规则,使得视觉抽象在很大程度上与查询无关,并限制了对小物体、空间细节、文本和微妙视觉属性等细粒度线索的访问。在本研究中,我们提出了层的混合(Mixture of Layers, MoL),这是一种在视觉补丁级别的指令条件层路由方法,能够动态聚合来自中间视觉编码器层的与查询相关的潜在表示。给定一个文本查询,MoL预测视觉编码器层的路由概率,并在图像级、补丁级或通过混合路由机制对所选隐藏状态进行 top-k 稀疏聚合。通过这种方式,MoL 实现了对层特定视觉特征的查询自适应访问,以进行细粒度视觉推理。我们在 7 个细粒度视觉推理任务上的实验表明,性能有显著提升,特别是在细粒度视觉定位和理解任务上,与基线 MLLMs 相比,整体准确率提高了 +18.9%(在 V* 上)、+4.5%(在 HRBench4K 上)和 +16.3%(在 CharXiv 上),且无需采用多分辨率输入、简单交错多个视觉编码器或增加补丁令牌的数量。我们研究了不同层级视觉编码器的感受野尺度及其采样行为,以提供深入分析,解释为何层级采样是有益的,证明条件视觉表示是实现 MLLMs 更好视觉感知和推理的关键步骤。我们的项目页面可访问 https://wjdghks950.github.io/mol.github.io/.

TIRA: Tumor Immune Representation Adaptation for Zero-Shot Cross-Cancer MSI and TMB Prediction

TIRA:肿瘤免疫表征适应用于零样本跨癌症的微卫星不稳定性和肿瘤突变负荷预测
Raju, Dasari Naga
Abstract
Microsatellite instability-high (MSI-H) and high tumor mutational burden (TMB-H) are clinically relevant biomarkers, yet their histopathological prediction remains challenging when models are transferred across morphologically distinct cancer types. Immune-associated spatial patterns can persist across cancers despite these morphological differences, but foundation-model-based predictors trained on a single cancer do not explicitly use this information, limiting cross-cancer generalization. To address this limitation, we propose TIRA (Tumor Immune Representation Adaptation), a target-free framework that refines frozen foundation-model representations using spatial immune topology, without requiring target-domain data during model development or test-time adaptation. TIRA uses a topology-supervised biology representation to condition tile-level attention while pooling only morphological features for joint MSI and TMB prediction. We train TIRA on TCGA-COAD+READ and evaluate it zero-shot on CPTAC-COAD, TCGA-STAD, TCGA-UCEC, and CPTAC-UCEC, covering cross-site, cross-cancer, and combined cross-cancer-site distribution shifts under UNI2, CONCH, and Virchow2. With UNI2, TIRA improved zero-shot AUROC on TCGA-STAD from 0.633 to 0.766 for MSI and from 0.651 to 0.772 for TMB. Source-derived spatial immune topology improved the cross-cancer robustness of frozen pathology foundation-model representations.

微卫星不稳定性高(MSI-H)和高肿瘤突变负荷(TMB-H)是临床相关的生物标志物,但在不同形态学癌症类型之间转移模型时,其组织病理学预测仍然具有挑战性。尽管存在这些形态学差异,免疫相关的空间模式在不同癌症之间仍然可以持续存在,但基于基础模型的预测器在单一癌症上训练时并未明确利用这些信息,从而限制了跨癌症的泛化能力。为了解决这一限制,我们提出了TIRA(肿瘤免疫表征适应),这是一个无目标的框架,通过使用空间免疫拓扑来细化冻结的基础模型表征,而在模型开发或测试时适应过程中不需要目标领域数据。TIRA使用拓扑监督的生物学表征来调节瓷砖级别的注意力,同时仅汇聚形态特征以进行联合的MSI和TMB预测。我们在TCGA-COAD+READ上训练TIRA,并在CPTAC-COAD、TCGA-STAD、TCGA-UCEC和CPTAC-UCEC上进行零样本评估,涵盖了在UNI2、CONCH和Virchow2下的跨站点、跨癌症和组合跨癌症-站点分布转变。在UNI2下,TIRA将TCGA-STAD的零样本AUROC从0.633提高到0.766(MSI),从0.651提高到0.772(TMB)。源导向的空间免疫拓扑提高了冻结病理基础模型表征的跨癌症鲁棒性。

LighTROcc: Lightweight 4D Occupancy Forecasting via Instance-Centric 3D Gaussians

LighTROcc:通过实例中心的3D高斯实现轻量级4D占用预测
Jung, Hwanhee, Kim, SeungHyeon, Koo, Inkyu, Huang, Qixing, Yoon, Sang Ho, Kim, Sangpil
Abstract
Forecasting future 3D occupancy from surround-view cameras is essential for autonomous driving, yet existing approaches rely on dense voxel or bird's-eye-view representations whose cost grows rapidly with spatial resolution and prediction horizon. Because these representations do not explicitly maintain object identities, they also struggle to preserve instance consistency over time. We present LighTROcc, a lightweight instance-centric framework that represents movable objects with a compact set of learned queries and predicts present and future occupancy in a single forward pass. LighTROcc localizes each query through attention-guided forward lifting, combining image-space cross-attention, query-specific depth, and camera geometry to estimate its 3D center. Each instance is modeled as a mixture of anisotropic 3D Gaussians and propagated across future steps using predicted displacements, producing continuous, temporally consistent occupancy forecasts. Experiments on nuScenes and supplemented nuScenes-Occupancy show that LighTROcc outperforms the evaluated dense and instance-wise baselines in instance-level forecasting accuracy while maintaining strong voxel-level occupancy quality. Across different model configurations, LighTROcc achieves a favorable balance between forecasting accuracy and computational efficiency, demonstrating the potential of compact instance-centric modeling for camera-based 4D occupancy forecasting.

From Global Alignment to Local Grounding: Zero-Shot Chinese Character Recognition with Radical Verification

从全局对齐到局部定位:基于部首验证的零样本中文字符识别
Shih, Yu-Heng, Wu, Bing-Chen, Wong, Tsz-To, Yen, Ting-En, Shuai, Hong-Han, Hsieh, Bin-Hua, Chen, Chien-An, Yeh, Yi-Ren, Huang, Ching-Chun
Abstract
Zero-shot Chinese character recognition (ZS-CCR) aims to recognize characters whose categories are never observed during training, and typically relies on the compositional structure shared between seen and unseen characters. Recent CLIP-style methods represent this structure with the Ideographic Description Sequence (IDS) and align it with glyph images in a shared embedding space. However, they rely on a single global image--IDS similarity that discards the spatial layout of radicals and, being learned only implicitly from seen classes, generalizes poorly to unseen ones; moreover, global matching often retrieves the correct character within the top candidates yet fails to rank it first when characters differ only in subtle local radicals. To address these issues, we propose a global-to-local two-stage framework. In the first stage, STG-CLIP augments the IDS with explicit tree-position and radical-level geometric priors, yielding a spatial-aware prototype that provides a consistent spatial description across seen and unseen categories for high-recall global retrieval. In the second stage, the Radical Verification Module (RVM) uses the radical instances of each retrieved candidate as queries to verify whether the corresponding radicals can be matched to spatially compatible regions in the input glyph. A margin-based gating rule activates the RVM only when the leading global candidates receive similar similarity scores. Experiments on the ICDAR2013 benchmark demonstrate that our method achieves state-of-the-art performance under the character-level zero-shot setting, obtaining 83.06% top-1 accuracy with 2,755 seen classes. Ablation studies further show that the explicit geometric priors and radical-level verification provide complementary improvements.

零样本中文字符识别(ZS-CCR)旨在识别在训练过程中从未观察到的字符类别,通常依赖于已见字符和未见字符之间共享的组合结构。最近的 CLIP 风格方法通过表意描述序列(Ideographic Description Sequence, IDS)来表示这一结构,并将其与字形图像对齐于共享的嵌入空间。然而,这些方法依赖于单一的全局图像-IDS 相似性,忽略了部首的空间布局,并且由于仅从已见类别中隐式学习,导致对未见类别的泛化能力较差;此外,全局匹配通常能够在前几个候选中检索到正确的字符,但在字符仅在细微的局部部首上有所不同的情况下,未能将其排名第一。为了解决这些问题,我们提出了一种从全局到局部的两阶段框架。在第一阶段,STG-CLIP 通过显式的树位置和部首级几何先验增强 IDS,生成一个空间感知的原型,为已见和未见类别提供一致的空间描述,以实现高召回率的全局检索。在第二阶段,部首验证模块(Radical Verification Module, RVM)使用每个检索候选的部首实例作为查询,以验证相应的部首是否可以与输入字形中的空间兼容区域匹配。当领先的全局候选接收到相似的相似性分数时,基于边际的门控规则激活 RVM。在 ICDAR2013 基准上的实验表明,我们的方法在字符级零样本设置下实现了最先进的性能,获得了 83.06% 的 top-1 准确率,涉及 2,755 个已见类别。消融研究进一步表明,显式几何先验和部首级验证提供了互补的改进。

Iris-3B: Going Beyond the Latent with Pixel-Space Diffusion Training, Conversion and Fine-Tuning

Iris-3B:超越潜在空间的像素空间扩散训练、转换与微调
Cai, Hanqiu Li, Garabito, Chema
Abstract
Pixel-space diffusion models avoid the lossy VAE of latent models, which suggests an advantage on downstream tasks where fine-grained detail matters. We test this claim along both routes to a pixel-space backbone. We pretrain Iris-3B, a 3B-parameter pixel-space text-to-image transformer, from scratch through a $256\to512\to1024$ curriculum, after first ablating the prediction target and representation alignment at $256^2$ to decide what to scale. We also convert a pretrained latent model, FLUX.2 Klein base 4B, to pixel space. We fine-tune both families for monocular depth estimation and for image restoration/super-resolution. We find no significant improvement from using a pixel-space generative prior. Fine-tuned for depth with one matched direct-regression recipe, Iris-3B is level with the latent FLUX.2 Klein and the converted pixel FLUX.2 Klein falls behind it, and on $4\times$ DIV2K restoration neither pixel model beats a latent FLUX.2 Klein fine-tune, the converted one trailing it slightly. We document the recipes, the failure modes and the remaining confounds behind this negative result. Nevertheless, Iris-3B shows that pixel-space pretraining with the pixel-transformer (PiT) head of PixelDiT scales to 3B parameters and to text-to-image quality competitive with latent models, matching Qwen-Image on OneIG under the official evaluators at $1024^2$. We release its weights and training code in the hope that they help pave the way for further work on pixel-space generation.

RLHND: Video Foundation Models as Physically Grounded Hand Trackers for Robot Learning

RLHND:作为物理基础的手部追踪器的视频基础模型在机器人学习中的应用
Moon, Seungjun, Jeon, Subin, Kim, Sangwoo, Joo, Hanbyul, Shin, Jinwoo
Abstract
Recently, approaches that leverage human video datasets for robot policy training have become increasingly prevalent. However, most existing hand trackers regress pose from cropped frames with limited priors on hand motion and object interaction, resulting in inaccurate and physically inconsistent estimates. Moreover, the lack of physical cues, e.g., contact and force, limits the use of human videos for robot policy training. To this end, we propose RLHND, a video foundation model-based hand tracking model that jointly estimates hand pose and realistic tactile information from monocular egocentric videos. RLHND turns the pre-trained Cosmos 3 video diffusion backbone into a deterministic clip-level feature extractor via clean-latent conditioning, carrying its learned priors on hand motion and hand-object interaction into tracking. For pose estimation, RLHND (i) predicts hand poses with anatomically plausible joint angles and (ii) enables optional conditioning on the shape parameter to maintain consistent hand shape within the same video and even across videos recorded by the same actor. For tactile estimation, a separate tactile expert stream, trained with the pose stream frozen, predicts dense contact and force over the hand surface. We further adopt LBS-based feature spreading to enable vertex-wise feature extraction without costly per-vertex attention. RLHND achieves state-of-the-art performance across various benchmark datasets for pose estimation, while also achieving state-of-the-art performance in contact and force estimation. Moreover, we demonstrate the utility of RLHND for robot learning through retargeting results and real-world robot experiments. The code will be publicly available at https://seungjun-moon.github.io/rlhnd/.

近年来,利用人类视频数据集进行机器人策略训练的方法变得越来越普遍。然而,大多数现有的手部追踪器从裁剪的帧中回归姿态,缺乏对手部运动和物体交互的有限先验,导致估计不准确且在物理上不一致。此外,缺乏物理线索,例如接触和力,限制了人类视频在机器人策略训练中的使用。为此,我们提出了RLHND,一种基于视频基础模型的手部追踪模型,它从单目自我中心视频中联合估计手部姿态和真实的触觉信息。RLHND通过干净潜在条件将预训练的Cosmos 3视频扩散骨干网络转变为确定性的片段级特征提取器,将其在手部运动和手物体交互方面的学习先验融入追踪中。在姿态估计方面,RLHND (i) 预测具有解剖学上合理的关节角度的手部姿态,并且 (ii) 允许对形状参数进行可选条件,以在同一视频内甚至在同一演员录制的不同视频之间保持一致的手部形状。在触觉估计方面,单独的触觉专家流在冻结姿态流的情况下进行训练,预测手部表面的密集接触和力。我们进一步采用基于LBS的特征传播,以实现无需昂贵的逐顶点注意力的逐顶点特征提取。RLHND在各种基准数据集上实现了姿态估计的最先进性能,同时在接触和力估计方面也达到了最先进的表现。此外,我们通过重定向结果和现实世界的机器人实验展示了RLHND在机器人学习中的实用性。代码将公开发布在 https://seungjun-moon.github.io/rlhnd/。

An Invariant Tangent-Angle Descriptor and a Band U-Net for 2D Fragment Adjacency Prediction

一种不变的切线角描述符和用于二维碎片邻接预测的带状 U-Net
Brouillette, Guillaume, Goupil, Alain, Parisé, Pierre-Olivier, Touré, Fadel
Abstract
This paper addresses the prediction of adjacency between pairs of 2D fragments based on their contours. We improved the two-stage architecture proposed in Beaulac's thesis, in which a rotation-equivariant Siamese convolutional neural network scores pairs of local image windows along the two contours of two fragments. The scores are gathered in an adjacency matrix in which a ResNet detects the partial anti-diagonal band that reveals the adjacency of two fragments. In the current work, we keep the pipeline and replace the local score by a comparison of tangent-angle profiles of contour windows, making it, by construction, invariant to fragment rotation and agnostic to the selected contour-starting point. These adaptations may be either a training-free likelihood ratio or a small one-dimensional convolutional model trained on corresponding points. We also replaced the final classifier by a band U-Net that segments the band and classifies the pair, so that the shared arc is obtained along with the decision. In the synthetic data set of the original thesis, the tangent descriptor performs as well as or better than the image-window approach in all tested configurations. The proposed pipeline reaches an accuracy of 98%, vs 93% to 95% for the original approach once its evaluation is corrected. We tested our pipeline, with models trained only on synthetic data, on the PairingNet benchmark, and obtained an AUC of 0.93. Furthermore, under the PairingNet pair-searching protocol conditions, our learned descriptor obtains a Recall@10 of 0.82 on the real set against 0.56 from the best model of the original paper.

InstanceBench: Diagnosing Referential Reasoning and Target Identity in Referring Expression Segmentation

InstanceBench:诊断指称推理和指称表达分割中的目标身份
Li, Yuchen, Zhou, Shaoyang, Wang, Yiran, Deng, Ruiyi, Wang, Haoyu, Wei, Ziru, Zhao, Zhen, Zhou, Luping
Abstract
Referring Expression Segmentation (RES) links natural-language descriptions to pixel-level object masks. Yet standard evaluation provides limited insight into instance-level referential reasoning: it does not systematically distinguish referential logics, test target preservation across valid grounding paths, or separate target-selection from mask-generation errors. We introduce InstanceBench, an instance-centered diagnostic benchmark comprising 6,194 images, 9,264 target instances, and 25,077 human-verified expressions. Each target-centric expression set (TCES) fixes the image and target mask while pairing a minimal expression with a same-target variant that uses another valid cue or grounding path. A compact referential-logic taxonomy spans direct target evidence, same-class selection, relational and compositional grounding, and exclusion, while logic-critical construction suppresses simpler shortcuts. Identity-aware metrics measure target retention and set-level success while separating selection from mask-generation errors. Across 22 native-mask RES checkpoints from 18 model families, the strongest checkpoint reaches 67.1% mIoU but only 59.6% [email protected]. Controlled interventions confirm language sensitivity, while failure decomposition identifies target selection rather than mask decoding as the main bottleneck. On a controlled training subset, matched supervision improves identity-aware performance, showing that the diagnosed capability responds to targeted supervision. Collectively, InstanceBench supports a measure-diagnose-improve cycle: measuring target consistency across grounding paths, localizing failure sources, and evaluating targeted interventions.

Gaussian Material Fields for Volumetric Multi-Energy CT Decomposition

用于体积多能CT分解的高斯材料场
Lin, Jian, Fang, Jiancheng, Shan, Hongming, Wang, Shaoyu, Chen, Yang, Liu, Qiegen
Abstract
Volumetric material decomposition in multi-energy computed tomography requires a representation that organizes multiple three-dimensional material fields in a common spatial domain while retaining differences in composition and local structure. We observe that spatial primitives can be shared across materials without tying their coefficients, but their local capacity must respond to material-specific reconstruction needs. We introduce Gaussian material fields, which represent multiple material distributions with shared anisotropic 3D Gaussian primitives and independent nonnegative material coefficients. The shared geometry defines a continuous spatial basis, while the coefficients determine each primitive's contribution to the individual material fields. To reconstruct this representation from multi-energy projections, a differentiable spectral forward model combines Gaussian material path integrals with a calibrated basis matrix, enabling joint optimization of spatial geometry and material composition. Material-aware adaptive density control retains material-specific refinement evidence before aggregation and adjusts local representation capacity to accommodate both spatially extensive components and sparse details. Experiments use synthesized multi-energy projections generated from pseudo-reference material maps constructed by conventional methods from publicly available CT data. Across 15 cases, our approach improves average PSNR by 4.03 dB and SSIM by 4.96% over the strongest baseline, while reducing NRMSE by 33.45%. Material-wise comparisons and component ablations support improved recovery of localized structures, while runtime and memory measurements show favorable computational scaling. These results establish Gaussian material fields as an explicit, adaptive representation for volumetric multi-material reconstruction.

Clinical vision models are often deployed as frozen black boxes with no access to internals, retraining, or ground truth at inference time. We introduce \textbf{SpatialUQ}, a post-hoc uncertainty method using only output probabilities. It measures the Jensen-Shannon divergence between the global prediction and the mean of five fixed spatial crops in six deterministic forward passes. The premise is simple, trustworthy predictions are spatially consistent. On NIH ChestX-ray14 (DenseNet-121, $N{=}25{,}596$), our Multicrop Uncertainty Score (MUS) reaches $0.784$ failure-detection AUC versus $0.664$ for MC-Dropout ($p{<}10^{-6}$) at one-fifth the compute, with native calibration ($\text{SCE}{=}0.049$ vs.\ $0.127$ for $\ell_1$), the best-calibrated among methods above 0.78 AUC. A supervised fusion of MUS with entropy, confidence, and $\ell_1$ reaches $0.832$, outperforming a five-member ensemble ($0.813$). MUS scales with model quality, reaching $0.899$ with BiomedCLIP ($\rho = 0.846$), while this relationship remains meaningful in-distribution ($\rho = 0.523$) but breaks down under severe distribution shift (VinBigData, $\rho = 0.027$). MUS is well-suited to diffuse findings but is less dependable for small focal lesions such as nodules.

RT-DETR-World: Transferring Rich LLM Semantics to Real-Time Open-Vocabulary Detection

RT-DETR-World:将丰富的LLM语义转移到实时开放词汇检测
Zhang, Yupeng, Zhao, Ziyi, Cheng, Juntao, Wang, Sheng, Guo, Ningnan, Han, Ruize, Wan, Liang
Abstract
Open-vocabulary detection (OVD) recognizes categories unseen during training through textual category queries, yet achieving strong generalization with real-time efficiency remains challenging. Beyond vocabulary scaling, zero-shot generalization may benefit from reusable visual--semantic cues learned from seen data, including attributes, actions, states, and contextual relations. Existing real-time OVD methods primarily emphasize vocabulary coverage and efficient region/query--text matching; under strict efficiency constraints, compact detectors may struggle to absorb rich instance semantics and scene context. We propose RT-DETR-World, a compact DETR-style detector that transfers the rich semantics conveyed by descriptions during training while retaining lightweight query--text matching at inference. We construct GroundingCapv2 with three levels of supervision: category names for standard OVD, object descriptions conveying instance-level semantics, and image descriptions conveying object relations and scene context. These descriptions serve only as training-time semantic supervision. To help the compact detector absorb these semantics, we propose Dual-Path Description Alignment (DDA), combining a deployment-consistent MiniLM pathway with a training-only LLM teacher. MiniLM provides query--category supervision and object-description alignment, while offline teacher features supervise matched queries and global visual representations at the object and image levels, respectively. All teacher features are precomputed, and the teacher-side modules are removed after training. We further propose Relation-Aware Negative Relaxation (RNR), which uses teacher-derived semantic similarities to relax related negatives while preserving exact positives. Experiments demonstrate competitive zero-shot accuracy and a favorable accuracy--efficiency trade-off. The code will be released.

开放词汇检测(OVD)通过文本类别查询识别训练期间未见过的类别,但在实现强泛化和实时效率方面仍然面临挑战。除了词汇扩展,零样本泛化可能受益于从已见数据中学习到的可重用视觉-语义线索,包括属性、动作、状态和上下文关系。现有的实时OVD方法主要强调词汇覆盖和高效的区域/查询-文本匹配;在严格的效率限制下,紧凑型检测器可能难以吸收丰富的实例语义和场景上下文。我们提出了RT-DETR-World,这是一种紧凑的DETR风格检测器,它在推理时保留轻量级的查询-文本匹配,同时转移训练期间描述所传达的丰富语义。我们构建了GroundingCapv2,采用三层监督:用于标准OVD的类别名称、传达实例级语义的对象描述,以及传达对象关系和场景上下文的图像描述。这些描述仅作为训练时的语义监督。为了帮助紧凑型检测器吸收这些语义,我们提出了双路径描述对齐(DDA),结合了与部署一致的MiniLM路径和仅用于训练的LLM教师。MiniLM提供查询-类别监督和对象描述对齐,而离线教师特征分别在对象和图像级别监督匹配查询和全局视觉表示。所有教师特征都是预计算的,教师侧模块在训练后被移除。我们进一步提出了关系感知负放松(RNR),利用教师导出的语义相似性来放松相关的负样本,同时保留确切的正样本。实验表明,模型在零样本准确性方面具有竞争力,并且在准确性与效率之间取得了良好的平衡。代码将会发布。

TERRA: Learning Transportable Latent Actions through Temporal Effect Representation and Relational Alignment

TERRA:通过时间效应表示和关系对齐学习可传输的潜在动作
Ding, Tianxingjian, Shah, Mubarak, Tian, Yu
Abstract
Latent actions supervise robot policies with action-like codes inferred from visual transitions, and their usefulness hinges on two questions: what a code keeps from a transition, and whether it still means the same thing when reused in a different initial state. The first is a tension in time: an endpoint difference discards how motion unfolds, while the full sequence admits nuisance variation. The second is left open by reconstruction, which only ever observes a latent together with the state it came from. We argue that both questions can be answered in the same place. TERRA (Temporal Effect Representation and Relational Alignment) describes a transition by a compact temporal effect, its net feature change together with a low-order within-window dynamics component, and learns a continuous latent from this effect. The same effect space then serves as the reference for reuse: Effect-Anchored Transport (EAT) decodes a latent in other initial states and anchors the resulting effect to the one observed at its source, so that the latent is shaped by what it does across contexts rather than only by the transition it came from. With frozen linear readers, TERRA predicts actions more accurately than UniVLA and a LAPA-style baseline, degrades more slowly under visual distractors, and keeps transported transitions faithful to the donor action as the recipient context moves farther away; a same-budget control shows that these gains come largely from EAT. At matched pretraining scale, the complete system reaches 93.4% average success on LIBERO, compared with 91.8% for UniVLA.

潜在动作通过从视觉转变推断出的类动作编码来监督机器人策略,其有效性取决于两个问题:编码从转变中保留了什么,以及在不同初始状态下重新使用时是否仍然意味着相同的东西。第一个问题涉及时间的紧张关系:端点差异忽略了运动的展开,而完整序列则允许干扰变化。第二个问题则因重构而悬而未决,重构仅观察到潜在状态及其来源状态。我们认为这两个问题可以在同一处得到解答。TERRA(时间效应表示和关系对齐)通过紧凑的时间效应描述转变,其净特征变化以及低阶的窗口内动态成分,并从这一效应中学习连续的潜在状态。相同的效应空间随后作为重用的参考:效应锚定传输(Effect-Anchored Transport, EAT)在其他初始状态中解码潜在状态,并将得到的效应锚定到其源头观察到的效应上,从而使潜在状态受到其在不同上下文中所做的事情的影响,而不仅仅是来自于其转变。使用冻结的线性读取器,TERRA比UniVLA和LAPA风格的基线更准确地预测动作,在视觉干扰下降级更慢,并且在接收上下文逐渐远离时保持传输转变忠实于捐赠动作;同样预算的对照实验表明,这些提升主要来自EAT。在匹配的预训练规模下,完整系统在LIBERO上达到了93.4%的平均成功率,而UniVLA为91.8%。

LiG-DETR: Local-in-Global Reassembly in Latent Space for Aerial Object Detection

LiG-DETR:潜在空间中的全局-局部重组用于航空物体检测
Zhang, Yupeng, Gao, Fangzhuo, Cheng, Juntao, Zhao, Ziyi, Wan, Liang, Han, Ruize
Abstract
Aerial object detection faces substantial scale and density variations. Small objects are easily degraded by downsampling and feature compression, while medium and large objects require sufficient global context. Existing methods mainly follow two paradigms: image slicing provides clearer local evidence but relies on independent crop-level prediction and post-processing, whereas feature- and query-level optimization preserves unified inference but operates on already compressed full-image representations, limiting recovery of fine-grained information. This raises a key question: can aerial detection directly acquire high-fidelity local evidence before feature degradation and integrate it into a unified end-to-end framework? To this end, we propose LiG-DETR, an Efficient Global-Local Reassembly framework that reformulates image slicing as high-fidelity local feature acquisition. A shared encoder extracts global and locally magnified features, which are projected into the detector feature space. The projected local features are reassembled according to their original spatial locations to form a globally aligned local feature level, and a single DETR decoder jointly decodes global and local features. To reduce redundant computation, Context-Preserved Selective Reassembly focuses high-resolution encoding on informative regions while preserving a dense feature layout, and Density-Aware Adaptive Query Allocation adapts the decoder query budget using encoder proposal scores. Experiments show substantial gains on small and medium objects while retaining strong large-object performance, with favorable accuracy--efficiency trade-offs and improved cross-domain generalization. The code will be released.

航空物体检测面临显著的尺度和密度变化。小物体容易因下采样和特征压缩而退化,而中大物体则需要足够的全局上下文。现有方法主要遵循两种范式:图像切片提供更清晰的局部证据,但依赖于独立的裁剪级预测和后处理;而特征和查询级优化则保留统一推理,但在已经压缩的全图表示上操作,限制了细粒度信息的恢复。这引发了一个关键问题:航空检测能否在特征退化之前直接获取高保真局部证据,并将其整合到统一的端到端框架中?为此,我们提出了LiG-DETR,一个高效的全局-局部重组框架,将图像切片重新表述为高保真局部特征获取。共享编码器提取全局和局部放大特征,这些特征被投影到检测器特征空间中。投影后的局部特征根据其原始空间位置重新组合,以形成全局对齐的局部特征层,而单个DETR解码器则共同解码全局和局部特征。为了减少冗余计算,保留上下文的选择性重组将高分辨率编码集中在信息丰富的区域,同时保留密集的特征布局;而密度感知自适应查询分配则利用编码器提议分数调整解码器查询预算。实验表明,在保持强大大物体性能的同时,小物体和中物体的性能显著提升,具有良好的准确性-效率权衡和改进的跨域泛化能力。代码将会发布。

OmniCam: Omni-Camera Trajectory Generation via Geometry-Grounded Pose Token Learning

OmniCam:通过几何基础的姿态标记学习生成全景相机轨迹
Liu, Zhenyang, Cao, Chenjie, Zhang, Yisu, Zuo, Xuhui, Xue, Xiangyang, Fu, Yanwei, Wang, Tengfei, Guo, Chunchao
Abstract
Camera trajectories control viewpoint changes in video generation, scene reconstruction, and robotic perception. Generating them from language requires both scene geometry and target-aware framing. We introduce OmniCam, an autoregressive model that generates camera pose sequences from a single panorama and textual trajectory descriptions. Its geometry-grounded pose token learning combines three components: a panoramic point-cloud encoder for omnidirectional geometric context; hybrid absolute-rotation and relative-translation tokenization with temporally consistent quaternion signs; and separate geometric and semantic conditioning streams with an explicit 3D target anchor. We also construct OmniCaT, containing 267,700 trajectories across four camera behaviors. On the reported OmniCaT evaluation, OmniCam reduces trajectory errors by 28--47% and collision rate by 65.8% relative to GenDoP retrained on OmniCaT. Against the best baseline for each metric, the ATE and collision reductions are 43.0% and 62.3%, respectively. Component ablations support the use of geometric and target-aware conditioning, while downstream experiments examine camera-controlled video generation and robotic active perception.

STRIKE: Learning Visual State Transitions for Physical World Modeling

STRIKE:用于物理世界建模的视觉状态转移学习
Teng, Wenbin, Xu, Tianshuo, Meng, Depu, Li, Yuelei, Herau, Quentin, Hu, Yihan, Zhao, Yajie, Zhan, Wei
Abstract
Physical world modeling requires predicting how interactions change a scene, not merely generating coherent motion. We propose STRIKE, a framework that separates visual state transition learning from dense video generation. We construct event-aligned supervision by extracting observed states from training videos and pairing them with transition descriptions and temporal offsets. An image-based transition model learns to predict the next scene configuration from the current image, a local transition specification, and elapsed time. At inference, a pretrained vision-language planner predicts time transition specifications, and recursive application of the learned transition model produces a sequence of future visual states. A separately trained dynamic model then generates the complete rollout conditioned on these states and their temporal locations. Experiments on Physics-IQ Verified, PhyGenBench, Pisa-Experiments, and RoboTwin2.0 show improvements of STRIKE over the corresponding video-backbone baselines in benchmark measures of physical consistency and manipulation-video fidelity. These results support learned visual state transitions as an effective intermediate representation for physical world modeling.

It Is Not Seeing the Hazard: A Frozen Vision-Language Safety Score Measures Its Caption Bank

看不到危险:一个冻结的视觉-语言安全评分衡量其描述库
Tetteh, Samuel, Fleming, Cody
Abstract
Frozen vision-language models increasingly provide safety signals for reinforcement learning. Their use assumes that similarity to language describing danger indicates the hazard itself. Yet policy return and collision rate cannot reveal whether a score detects hazards or responds to correlated features of the scene. VLM-based methods have reported gains in driving and safe-RL benchmarks by converting image-text similarity into rewards, costs, or confidence weights. Such signals promise to reduce reliance on manually designed feedback. They may also reflect prompt structure, embedding geometry, or camera viewpoint, leaving their safety meaning unverified. To address this gap, we present a controlled evaluation of a frozen CLIP prompt-margin safety score. We apply the score to trajectories generated by policies that never receive it, match pre-contact observations to contact-free observations with comparable hazard geometry, and vary the captions, encoder, and camera view. Across three policies, 180 episodes, and 130 isolated contact onsets, the score decreases for about twenty steps before contact. Mechanism controls indicate that the score mainly tracks resemblance to the scene shared by its captions and changes with caption separation and camera view. A constant-confidence control retains the lower catastrophe-rate point estimate, so policy gains do not establish hazard perception.

冻结的视觉-语言模型越来越多地为强化学习提供安全信号。它们的使用假设与描述危险的语言相似性表明了危险本身。然而,政策回报和碰撞率无法揭示一个评分是否检测到危险,或是对场景的相关特征做出反应。基于视觉-语言模型(VLM)的方法通过将图像-文本相似性转化为奖励、成本或置信权重,在驾驶和安全强化学习基准测试中报告了收益。这些信号有望减少对手动设计反馈的依赖。它们也可能反映提示结构、嵌入几何或相机视角,使其安全含义未得到验证。为了解决这一问题,我们提出了对一个冻结的CLIP提示边际安全评分的控制评估。我们将该评分应用于从未接收到该评分的策略生成的轨迹,将接触前的观察与具有可比危险几何的无接触观察进行匹配,并改变标题、编码器和相机视角。在三个策略、180个回合和130个孤立接触起始点中,该评分在接触前约二十步内下降。机制控制表明,该评分主要跟踪与其标题共享的场景的相似性,并随着标题分离和相机视角的变化而变化。一个常量置信控制保留了较低灾难率的点估计,因此政策收益并未建立危险感知。

ActiveLang: Active Open-Vocabulary 3D Mapping with Semantic-Uncertainty-Guided Exploration

ActiveLang:基于语义不确定性引导探索的主动开放词汇3D映射
Chen, Liyan, Yin, Hairong, Zhan, Huangying, Xu, Yi, Yeh, Raymond A., Mordohai, Philippos
Abstract
As robots increasingly assist humans with diverse tasks, they need both geometric and semantic understanding of their surroundings. Moreover, robots often operate in unfamiliar environments and take on new tasks without knowing the relevant concepts ahead of time. This motivates language-annotated 3D maps that support open-vocabulary scene understanding and human-robot interaction. We introduce ActiveLang, an autonomous system for active open-vocabulary 3D mapping with semantic-uncertainty-guided exploration. ActiveLang performs online language-feature adaptation on a compact dual-Gaussian representation to jointly reconstruct scene geometry, appearance, and open-vocabulary semantics with modest memory overhead. Its planner efficiently selects informative viewpoints, enabling effective mapping with fewer observations and lower computational cost. Experiments on Replica and ScanNet++ demonstrate substantial improvements in 2D and 3D open-vocabulary segmentation over both online and offline baselines, highlighting that actively exploring scenes builds language-annotated 3D maps more efficiently.

KASALv2: Fully Automatic 3D Rotational Symmetry Classification and Axis Localization

KASALv2:全自动三维旋转对称性分类与轴定位
Zhang, Mengxin, Wang, Yulin, Luo, Chen, Li, Yongzhe, Zhou, Yijun
Abstract
Rotational symmetry is an important prior in 6D pose estimation, improving pose accuracy and supporting symmetry-aware evaluation. However, current symmetry annotations for 3D objects remain largely manual or semi-automatic, often requiring predefined types or orders, which limits scalability. This work introduces a fully automatic, reference-free framework for symmetry-type classification, rotational-order identification, and full-axis localization across all eight canonical 3D rotational symmetry types. The method localizes a dominant high-order axis, infers its rotational order through self-consistency analysis, and reconstructs the complete symmetry structure under a hierarchy-guided formulation. A texture-aware extension further models appearance-induced reductions in rotational order while preserving axis orientations. Experiments on idealized and real-world datasets demonstrate strong accuracy and generalization, achieving 94.75% accuracy on 438 symmetric objects in GSO. Training FoundationPose with these priors improves accuracy by up to 0.9% across five BOP datasets, showing that automatically estimated rotational priors improve downstream 6D pose estimation.

WAPR: A Foundation Model for Wide-Angle Refinement in Unseen Object Pose Estimation

WAPR:一种用于未见物体姿态估计的广角精细化基础模型
Wang, Yulin, Hu, Mengting, Li, Hongli, Zhou, Jianghao, Luo, Chen
Abstract
Real-world applications require 6D pose estimation to be accurate, fast, and scalable to unseen objects. This paper introduces WAPR, a zero-shot wide-angle pose refinement model that refines candidate poses with rotational deviations up to 90 degrees. With as few as 12 candidate poses per detected object instance, WAPR supports fast inference within 1 s per frame and reaches a pose-estimation throughput of up to 25 detected object instances per second. To support wide-angle training for rotationally symmetric objects, WAPR uses rotational symmetry priors to canonicalize symmetry-equivalent pose targets before loss computation. We further construct SA6D, a large-scale 6D training dataset with such priors. SA6D obtains KASAL-assisted rotational symmetry priors for 944 GSO scans and expands them through geometry and texture augmentation into about 50K augmented object instances and about 2M rendered RGB-D images. In addition, an angle-balanced loss stabilizes learning across different angular ranges by reducing the influence of uninformative large-error cases. Experiments on seven BOP core datasets show that WAPR achieves state-of-the-art performance in unseen-object 6D pose localization and detection under both fast and unconstrained inference settings.

Visual Evidence Under Cross-Examination: Evaluating and Controlling Decision-Level Evidence Use in Vision-Language Models

交叉审查下的视觉证据:评估和控制视觉-语言模型中的决策级证据使用
Zhang, Huiyao, Bai, Jin, Su, Zilong, Guo, Rui, Qin, Chaofan, Lv, Jinze, Yu, Wenhui, Wang, Hongfei, Li, Ye
Abstract
Vision-language models increasingly reason through crops, regions, and tool-produced observations. Yet an observation can influence the answer without benefiting the candidate it supports. We study candidate-bound visual contribution: valid evidence should help, invalidating its supporting relation should remove its additional effect, and valid rebinding should redirect that effect to the newly supported candidate. We introduce CROSS-Bench, a benchmark of 28,000 decision problems, with matched invalidation and rebinding tests on a dedicated evaluation subset. Our RIVET interface preserves evidence identity and uncertainty, composes a candidate-conditioned response, and separately controls its strength. Shared-evidence experiments show that task accuracy and evidence ownership can diverge. Under matched capacity and training, RIVET increases normalized effect transfer from 0.512 to 0.651 where clean evidence has a positive effect. The advantage persists on common evaluation examples and across repeated decision-layer fits. With evidence predicted from raw inputs, RIVET improves CROSS-Bench accuracy by an average of 5.70 pp across four frozen backbones, relative to the same models without auxiliary evidence. These results separate the utility of visual evidence from the candidate-specific destination of its effect.

Gradient-Based Trajectory Optimisation over Continuous Poses for Sparse-View Cone-Beam CT

基于梯度的稀视角锥束CT连续姿态轨迹优化
Schneider, Linda-Sophie, Wittl, Simon, Herl, Gabriel, Maier, Andreas
Abstract
Trajectory optimisation for cone-beam computed tomography (CT) determines which information sparse-view scans acquire. Fixed candidate pools prevent off-grid refinement and require new object-specific precomputation for each acquisition manifold. We make every source pose an individual continuous variable and move all poses jointly by gradient ascent on the scanner's kinematic manifold. The objective combines soft-Tuy plane coverage, continuous View Covariance Loss, and an analytic attenuation-aware ray-bundle penalty. The same optimiser handles circular, limited C-arm, two-axis, and freesphere parametrisations. On a Defrise flange, continuous selection recovers laminar defects invisible to a circular orbit, matches discrete swap search on the free sphere at the sparser budget, and leads at the denser one, with the same objective evaluated in every arm. A moderate elevation band already recovers most of the free-sphere gain at the defects, so the same optimiser transfers to bounded scanner envelopes. Photon noise preserves the ordering on the flange and compresses it on a dense fuel nozzle. Sparseprescan planning benefits from matching prescan and planned acquisition manifolds. Selection takes seconds rather than minutes without an object-specific reconstruction basis. Prescan-planned poses were executed on a robot CT bench and reconstructed in a common frame, demonstrating feasibility but no consistent metric gain over uniform band sampling. Continuous pose optimisation incorporates attenuation and scanner constraints directly into sparse-view acquisition design.

STORK factorizes 3D spatio-temporal convolutions into parallel branches across temporal hyperplanes to capture coherent tissue motion without the cost of full 4D convolutions. Per-frame embeddings, combining intensity and Demons-estimated displacement fields, are aggregated by a linear mean-pooling head. This ensures that frame-level contraction scores can be recovered post-hoc without frame-level training supervision. Evaluated on around 700 multi-vendor dynamic fetal MRI series, STORK achieves a series-level AUROC of 95.0% and AUPRC of 94.6%, substantially outperforming 3D ResNet and ConvNeXt baselines. Grad-CAM analysis suggests that the model draws on predictive features extending beyond the placenta into the uterine tissue, offering an automated tool for richer phenotyping of uterine behavior.

在胎儿MRI中,子宫收缩通常是手动识别并被丢弃的,这限制了对收缩动态的深入理解。我们将子宫收缩活动检测(Uterine Contractile Activity Detection,UCAD)形式化为一个弱监督学习问题,并引入STORK,一个基于动态MRI序列的多实例学习模型,仅使用粗略的序列级标签进行训练。STORK将3D时空卷积分解为跨时间超平面的并行分支,以捕捉一致的组织运动,而无需进行完整的4D卷积。每帧嵌入结合了强度和Demons估计的位移场,通过线性均值池头进行聚合。这确保了可以在后期恢复帧级收缩得分,而无需帧级训练监督。在约700个多供应商动态胎儿MRI序列上进行评估,STORK实现了95.0%的序列级AUROC和94.6%的AUPRC,显著优于3D ResNet和ConvNeXt基线。Grad-CAM分析表明,该模型利用了超出胎盘延伸至子宫组织的预测特征,为子宫行为的更丰富表型提供了自动化工具。

Abstract
National-scale magnetic resonance imaging (MRI) repositories increasingly integrate data from different studies and institutions. However, subject identifiers that are valid only within individual datasets are no longer guaranteed to remain globally unique after aggregation, making it possible for the same subject to be assigned multiple identifiers, which we define as identity duplication. Such duplication can create leakage between training and test data and inflate apparent performance in downstream biomedical studies. Existing methods do not provide an end-to-end, image-based workflow for auditing this problem at repository scale. In this work, we present HAPPEN, a human-in-the-loop pipeline for auditing identity duplication in T1-weighted brain MRI repositories. It combines SHA-256 fingerprinting for exact-duplicate detection with supervised contrastive retrieval of non-identical scans that may originate from the same person. Retrieved pairs are reviewed as candidates in a locally hosted interface rather than automatically classified as duplicates. We deployed the workflow in a 95,129-scan aggregated repository and assessed end-to-end recovery using 54 genetic-reference pairs. Transferability was assessed by locally deploying the same workflow on 22,386 scans at an independent institution without model retraining or image transfer. Deployment in the study repository identified 1,316 exact-duplicate scan groups and 1,275 reviewer-supported near-duplicate subject groups. Of these groups, 56% and 82%, respectively, crossed dataset boundaries. All 54 genetic-reference pairs were recovered. The external team independently completed the full workflow using a locally selected operating threshold and review standard.

Quasi-Binarized Autoencoders: An Architecture-Independent Information Bottleneck for Medical Image Anomaly Detection

准二值化自编码器:一种架构无关的信息瓶颈用于医学图像异常检测
Hanaoka, Shouhei, Nakao, Takahiro, Takamatsu, Atsushi, Yoshikawa, Takeharu, Abe, Osamu
Abstract
Unsupervised anomaly detection, which learns only from normal images, is a central task in medical image analysis and remains an open problem. Reconstruction-based methods pass an image through an encoder-decoder network trained on normal data and detect anomalies from the residual between the image and its reconstruction. This works only if the information passed from the encoder to the decoder is limited; otherwise the network learns an identity mapping and reconstructs anomalies too. This limit is usually imposed through architectural choices, tuned per dataset, that cannot be stated in bits. We introduce the quasi-binarizing (QB) layer, which squashes each latent element into [0, 1] and adds Laplace noise of scale 1/epsilon. Each element is then epsilon-locally differentially private, and the mutual information between an image and its reconstruction is bounded by a quantity that depends only on epsilon and the number of QB elements, whatever the encoder and decoder. Placing a QB layer on every encoder-decoder path, including all skip connections, we build QBAE, a seven-level attention U-Net with 32,768 QB elements. On the seven datasets of the MedIAnomaly benchmark, QBAE with one architecture and one configuration reaches a mean image-level AUROC of 0.828, the highest among methods that do not adapt to each dataset, and the best reported results on BraTS2021 (AUROC 0.911, pixel-level AP 0.838). The noise is kept at test time, so that every reconstruction satisfies the bound. Without input corruption, the bottleneck alone prevents identity collapse (mean AUROC 0.805 vs. 0.590). Code is available at https://github.com/hanaokalog/MedIAnomalyQB.

无监督异常检测仅从正常图像中学习,是医学图像分析中的核心任务,仍然是一个未解决的问题。基于重建的方法通过在正常数据上训练的编码-解码网络传递图像,并从图像与其重建之间的残差中检测异常。这种方法只有在从编码器到解码器传递的信息受到限制时才有效;否则,网络会学习到身份映射并重建异常。这种限制通常通过架构选择施加,针对每个数据集进行调整,无法以比特数表示。我们引入了准二值化(QB)层,该层将每个潜在元素压缩到[0, 1]之间,并添加规模为1/epsilon的拉普拉斯噪声。每个元素在epsilon局部上是差分隐私的,图像与其重建之间的互信息被一个仅依赖于epsilon和QB元素数量的量所限制,无论编码器和解码器如何。在每个编码-解码路径上放置一个QB层,包括所有跳跃连接,我们构建了QBAE,一个具有32,768个QB元素的七层注意力U-Net。在MedIAnomaly基准的七个数据集上,QBAE以一种架构和一种配置达到了0.828的平均图像级AUROC,这是在不适应每个数据集的方法中最高的,并且在BraTS2021上报告了最佳结果(AUROC 0.911,像素级AP 0.838)。在测试时保持噪声,因此每个重建都满足限制。在没有输入损坏的情况下,仅瓶颈就能防止身份崩溃(平均AUROC 0.805对比0.590)。代码可在https://github.com/hanaokalog/MedIAnomalyQB获取。

A Multi-Source Ultrasound Benchmark Revealing the Limits of Contemporary Self-Supervised Anomaly Detection Methods

多源超声基准揭示当代自监督异常检测方法的局限性
Riedenauer, Marco, Kienzle, Daniel, Mayekar, Pratik, Lienhart, Rainer
Abstract
Self-supervised anomaly detection is a promising paradigm for medical ultrasound, as normal images are often easier to obtain than exhaustive annotations of all possible pathologies. However, most existing evaluations are limited to a single anatomy or task, making it unclear whether models learn a robust notion of normal ultrasound appearance or only a source-specific representation. We introduce the SADUSI benchmark, a multi-source ultrasound dataset designed to train and evaluate anomaly detection methods across a broad range of anatomical regions, views, and acquisition protocols. The goal of SADUSI is to provide a diverse normal ultrasound distribution and a benchmark for visible structural anomalies that can be assessed from single images. We evaluate representative self-supervised anomaly detection methods and find that current approaches struggle in this setting. In particular, reconstruction-based diffusion methods such as AnoDDPM and DeCo-Diff achieve pixel-level AUROC values of 0.56-0.72 and maximum F1 scores of 0.10-0.26, indicating limited separation of pathology from normal image regions. Feature-based PatchCore variants perform better, reaching pixel-level AUROC values of 0.76-0.83, but remain limited with maximum F1 scores of 0.14-0.40. These findings suggest that broad multi-source ultrasound anomaly detection remains an open challenge and that SADUSI can serve as a resource for developing methods that generalize beyond anatomy-specific settings.

自监督异常检测是医学超声领域一种有前景的范式,因为正常图像通常比对所有可能病理的详尽注释更容易获得。然而,现有的大多数评估仅限于单一解剖结构或任务,这使得不清楚模型是否学习到了稳健的正常超声外观概念,还是仅仅获得了特定来源的表示。我们引入了SADUSI基准,一个旨在跨广泛解剖区域、视图和采集协议训练和评估异常检测方法的多源超声数据集。SADUSI的目标是提供多样化的正常超声分布以及可通过单幅图像评估的可见结构异常的基准。我们评估了具有代表性的自监督异常检测方法,发现当前的方法在这一设置中表现不佳。特别是基于重建的扩散方法,如AnoDDPM和DeCo-Diff,其像素级AUROC值为0.56-0.72,最大F1分数为0.10-0.26,表明病理与正常图像区域的分离有限。基于特征的PatchCore变体表现更好,达到像素级AUROC值为0.76-0.83,但最大F1分数仍然有限,为0.14-0.40。这些发现表明,广泛的多源超声异常检测仍然是一个开放的挑战,而SADUSI可以作为开发超越特定解剖设置的通用方法的资源。

What Makes Synthetic Hard Negatives Work in Vision-Language Pretraining?

合成困难负样本在视觉-语言预训练中的有效性分析
Giakoumoglou, Nikos, Giakoumoglou, Paschalis, Floros, Andreas, Papadopoulos, Kleanthis Marios, Stathaki, Tania
Abstract
Synthetic hard negatives generated in the representation space have proven effective for unimodal self-supervised learning, but transferring this idea to vision-language pretraining is not straightforward. We analyze six representation-space synthesis strategies and identify two failure modes in their transfer to vision-language pretraining: cross-modal constructions that produce overly easy negatives or pull them toward the query, and intra-modal constructions that incorporate the matched positive. We also observe logit-scale saturation when training with synthetic hard negatives and a learnable temperature, and find that fixing the temperature improves downstream performance. Using this geometric analysis we propose SNAP, which generates intra-modal hard negatives that never involve the positive from either modality, avoiding both failure modes entirely. SNAP is model-agnostic, requires no external generative models, and adds less than 10% training time overhead. Evaluated on top of CLIP and FLIP across multiple architectures and datasets, SNAP delivers consistent improvements on zero-shot retrieval, zero-shot classification, and linear probe evaluation.

Latent Watermarks under Generative Editing: A Benchmark and Analysis of Detection Survival

生成编辑下的潜在水印:检测生存的基准与分析
Lee, Sung Ju, Cho, Nam Ik
Abstract
Ordinary prompt-based editing can cause latent watermark detection to fail without explicitly targeting the watermark. We benchmark eight watermark methods against five editors across four generative backbones, four editing strengths, and five semantic categories, with edit-validity and threshold checks. Separating editing from seven subsequent distortions reveals that editing alone primarily distinguishes Tree-Ring, while added distortions expose a broader spectrum of detection survival. Sequential edits reveal a second hidden difference: score separation can decline while detection rates remain near their ceiling. Across methods, standardized clean score separation ($d'$) organizes composite-survival tiers, whereas spatial overlap adds little to predicting edit-only survival beyond clean detectability. Embedding-strength interventions in two methods link higher clean separation to higher post-edit separation. In HSTR, the margin contrast is positive, while the angular layout contrast at matched clean separation remains unresolved. Together, outcome decomposition and continuous separation expose differences hidden by aggregate TPR. Method tiers are stable under threshold recalibration at the main operating points and alternative composite weights. Clean $d'$ is thus a useful empirical diagnostic within this benchmark, with mixed transfer to unseen methods. Code and supporting artifacts are planned for a separate release.

Enhancing Multi-Region Stylization with Interior-Guided Boundary Repair

基于内部引导的边界修复增强多区域风格化
Nguyen, Hong-Son, Le, Thi-Ngoc-Hanh
Abstract
Region-based neural style transfer enables fine-grained artistic control by allowing independent stylization of semantic image regions. However, compositing these regions often leads to boundary artifacts, degrading visual quality. We propose Interior-Guided Boundary Repair (IGBR), a lightweight and model-agnostic method that improves boundary handling in multi-region stylization. IGBR repairs boundary pixels using interior-guided propagation and applies inward, distance-based blending restricted to object-background boundaries, preventing inter-object style leakage. The method is derived from a region-wise constrained formulation with a closed-form solution and can be seamlessly integrated into existing stylization pipelines without retraining. To evaluate efficiency of our IGBR, we introduce quantitative metrics that measure boundary consistency, gradient artifacts, inter-object leakage, and interior preservation without requiring annotated stylized images. Our experiments and evaluations demonstrate that the proposed IGBR consistently produces plausible boundaries, outperforming prior blending techniques in boundary consistency, gradient stability, and interior preservation. The code is available at https://github.com/Son-SDT/IGBR.

DynStream: Online Streaming 4D Gaussian Reconstruction of Dynamic Worlds from Unposed Video

DynStream:从无姿态视频中在线流式重建动态世界的4D高斯模型
Xian, Dingwei, Zhou, Xiaoyu, Xiong, Yajiao, Wang, Yongtao, Yang, Ming-Hsuan
Abstract
Online reconstruction of dynamic 4D scenes from long, unposed streaming videos requires both continuous processing and photorealistic rendering, which existing methods struggle to achieve simultaneously. Existing feed-forward Gaussian methods are restricted to offline processing, whereas online point-cloud approaches struggle to maintain dense geometry and high-fidelity rendering. We present DynStream, a framework for streaming 4D Gaussian reconstruction from long, unposed videos. Given a continuous video stream, DynStream reconstructs the scene within local temporal windows and incrementally aligns and fuses these local reconstructions into a globally consistent scene, enabling online 4D reconstruction without per-scene optimization. By jointly enforcing cross-window geometric consistency and modeling time-varying scene content, DynStream supports efficient reconstruction and photorealistic rendering over extended video streams. Experiments demonstrate that DynStream enables high-fidelity online dynamic reconstruction and rendering from long video streams, achieving state-of-the-art performance across diverse dynamic indoor and outdoor scenes.

MeshCarve: Artisan Mesh Generation with Flow Matching in Compact Latent Spaces

MeshCarve:在紧凑潜在空间中进行流匹配的工艺网格生成
Wang, Xiyu, Wu, Ruocheng, Wang, Yufei, Li, Zhihao, Guo, Lanqing, Wen, Bihan
Abstract
Prior artisan mesh generation works largely predict face tokens autoregressively, which makes inference slow. Recent methods instead flow match continuous latents built by Variational AutoEncoders (VAEs), but reconstruction quality drops significantly when geometry and topology are jointly encoded, and further when the latent space is compressed. We present MeshCarve, a flow matching method that generates entirely in compact latent spaces, generating vertex positions and edge connections separately and sidestepping the difficulty of a joint compact latent. To shorten the token sequence, we propose a hierarchical sparse transformer backbone, instantiated as VertexVAE and EdgeVAE. Instead of encoding fields over the surface voxels, both VAEs anchor on discrete vertices in their latent spaces, which drastically reduces the token sequence length, and our spatial-aware compression shortens it further without costing reconstruction. VertexVAE directly encodes vertex occupancy. For connectivity, we propose vertex-link encoding, which turns arbitrary connectivity between vertices into fixed-length continuous per-vertex embeddings and recovers complex artistic topology faithfully. MeshCarve combines these VAEs with an anchor generator and flow matches on the shortened token sequences. It shows advantages over state-of-the-art autoregressive and flow matching methods on Objaverse and generalizes to Toys4K. To the best of our knowledge, it is among the first artisan mesh generation methods whose every generative stage runs in a spatially compressed latent, with a token sequence only a fraction of the most compressed previous autoregressive and flow matching works.

Beyond Group Splits: Specimen-Level Cross-Validation and Visual Attribution for Remaining-Shelf-Life Regression in Climacteric Fruit

超越组划分:用于气候果实剩余保质期回归的样本级交叉验证与视觉归因

Abstract
Estimating remaining shelf life (RSL) from images could provide affordable decision support for perishable produce, but evaluation protocols can substantially affect reported performance when repeated images are available from the same biological specimen. We use the Hass Avocado Ripening dataset, comprising 8,834 image-RSL pairs from 426 fruits across three storage regimes, to evaluate a frozen ImageNet-pretrained visual backbone with a lightweight regression head. Our contributions are threefold: we quantify the effect of observation-level versus specimen-disjoint evaluation, compare lightweight and heavier visual backbones under specimen-disjoint cross-validation, and examine their spatial attributions using Grad-CAM. Across ten observation-level random splits, the model achieves a mean RMSE of 2.37 days with a standard deviation of 0.03 days, whereas specimen-disjoint 5-fold cross-validation yields a mean RMSE of 3.12 days with a standard deviation of 0.11 days. The corresponding mean coefficient of determination is 0.553. A matched per-specimen comparison confirms higher error under specimen-disjoint evaluation, with a probability value below 0.001 across 426 specimens, showing that observation-level partitioning gives a substantially more optimistic estimate for this dataset and model configuration. Under specimen-disjoint evaluation, MobileNetV3-Small (0.93 million parameters) achieves accuracy comparable to ResNet-18 while providing substantially higher throughput, and Grad-CAM reveals differences in spatial attribution between the lightweight backbones. These results support specimen-disjoint evaluation and attribution analysis when assessing lightweight vision models for longitudinal shelf-life prediction.

SoccerNet-FoulRet: Retrieving Semantically Similar Soccer Foul Videos

Arthur, Jacobus, Sait, Ahmad, Hani, Batool, Ramazanova, Merey, Held, Jan, Van Droogenbroeck, Marc, Ghanem, Bernard, Cioppa, Anthony, Giancola, Silvio
Abstract
Refereeing decisions in professional soccer remain inconsistent because referees cannot easily compare a contentious foul against similar past cases. We cast this as a retrieval problem and introduce SoccerNet-FoulRet, the first benchmark for semantic foul retrieval. Given a query foul, the task is to retrieve past fouls judged to be relevant precedents, regardless of camera angle, teams, or appearance. This differs from prior video-to-video retrieval, which matches clips by visual similarity or a shared event. Here, relevance is defined by refereeing interpretation. We build the benchmark from the SoccerNet-MVFoul dataset and evaluate retrieval ability of zero-shot video and vision-language embedders together with a task-specific fine-tuned baseline on 693 human-verified queries and category-relevance labels. Semantic foul retrieval remains challenging. The strongest zero-shot model achieves under 5% HitRate@10 on human-verified precedents, while category-supervised fine-tuning improves category relevance but transfers only modestly to precedent retrieval. We release SoccerNet-FoulRet to establish semantic foul retrieval as an open problem: https://github.com/SoccerNet/sn-foulret.

Flow-of-Thought: A Framework for Visual Reasoning

思维流:一种视觉推理框架
Baidachna, Mariia, Pugeault, Nicolas
Abstract
Mental imagery, ``seeing with the mind's eye'' is an essential aspect of human cognition. Despite rapid progress Large Language Models (LLMs) and Vision Transformers (ViTs) still underperform on tasks requiring spatial understanding. To address this, we introduce Flow-of-Thought (FoT), a framework that integrates the generation of visual sketches as intermediate reasoning steps, mimicking mental imagery in humans. We train coordinate-aware trajectory flow fields on $SO(2)$ group orbits and cumulative shortest paths, then freeze the learned dynamics; same vs. different decisions compare competing generative hypotheses using foreground-weighted reconstruction energy. On locked tests FoT reaches 100.0% accuracy on Tetris and 99.0% on colored shapes. Under frozen transfer, the orbit-trained 2D flow improves over its endpoint-only control on BLINK Multi-view (72.2% vs. 63.9% on 133 public validation pairs), supporting continuous visual traces as an effective and interpretable representation for spatial reasoning in some out-of-distribution settings.

Diffusion-Generated Image Watermarking: A Two-Axis Taxonomy and Three Protocol-Bounded Case Studies

扩散生成图像水印:一个双轴分类法和三个协议约束的案例研究
Lee, Sung Ju, Cho, Nam Ik
Abstract
Watermarking diffusion-generated images requires balancing provenance signals with image quality, robustness, and computational cost. This work organizes methods along two axes: insertion mechanism and primary signal-bearing representation, and formalizes a representative $z_T$-Fourier pipeline for verification and identification. We then use the taxonomy to structure three protocol-bounded case studies. The first examines associations among frequency integrity, detection, quality, and cropping behavior. The second revisits persistence under seed-linked and seed-independent editing and formulates a scoped Semantic Imprinting Hypothesis without claiming a localized carrier or causal mechanism. The third studies single-shot VAE-latent phase modulation, including its efficiency, regeneration robustness, and robustness--quality operating points. Finally, we separate four content-level attack families from model/pipeline adaptation, propose corresponding evaluation protocols and testable conjectures for parameter-tuning threats, and identify additional temporal extensions for video. These analyses do not establish a universal ranking; instead, they provide a framework for matched, protocol-aware comparisons of watermarking systems for diffusion-generated images.

PARC-Loc: Text-to-Point-Cloud Localization with Partial Assignment and Relational Consistency

PARC-Loc:基于部分分配和关系一致性的文本到点云定位
Ma, Shengkai, Hou, Zhenyu, Cao, Weihua
Abstract
Text-to-point-cloud localization estimates a position in a city-scale 3D map from descriptions of surrounding objects. Existing coarse-to-fine methods retrieve submaps using aggregate learned compatibility and then localize within a selected submap. However, repetitive or similar urban objects can inflate the embedding similarity between the query and multiple submaps, even when the instance layout within a submap violates the query description. Meanwhile, query-relevant instances often span submap boundaries, leaving the retrieved submap with incomplete contextual evidence. We term these failure modes layout-inconsistent aliasing and boundary evidence incompleteness, respectively. To address them, we propose PARC-Loc, a coarse-to-fine localization framework built on Partial Assignment with Relational Consistency (PARC). PARC jointly models hint-object compatibility and pairwise spatial relations, allowing unmatched elements while favoring assignments consistent with the queried layout. At the coarse stage, its candidate-level assessment complements neural similarity for layout-consistent submap selection. At the fine stage, the context is expanded with query-relevant instances from adjacent submaps, while PARC yields object-level matching weights that guide cross-modal attention. Extensive experiments on KITTI360Pose and CityLoc show that PARC-Loc outperforms conventional coarse-to-fine baselines. On KITTI360Pose, our method improves Top-1 localization recall at 5 m from 0.50 to 0.67, achieving a 34% relative gain over the strongest baseline.

Relational Abstractions for Spatial Reasoning with Diffusion Models

基于扩散模型的空间推理关系抽象
Ezquerro, Ana, Özdenizci, Ozan
Abstract
Diffusion models excel at image synthesis, but they remain limited in their ability to reliably satisfy structured spatial reasoning constraints. In conditional data distribution modeling tasks with implicit logical structure, such as puzzles defined by visible clues paired with consistent solutions, state-of-the-art generative models tend to approximate pixel-space distributions without learning the underlying logical rules required for inference. To address this limitation, we present a novel framework for spatial reasoning with diffusion models that leverages unsupervised object discovery and abstractions of object relations. We show that the relational knowledge derived from object-centric representations enriches diffusion models with structural primitives, allowing them to effectively guide the generative representation space during both training and inference, and enabling conditional image generation that satisfies reasoning constraints. Additionally, we introduce a large-scale generative spatial reasoning benchmark with four datasets inspired by human-solvable puzzles. Our results show that relational abstractions significantly improve reasoning capabilities of diffusion models on a variety of complex reasoning tasks, while enabling robust generalization in out-of-distribution settings.

CIRSeg: Coarse-to-Fine Intensity-Robust Liver Segmentation with Source-Free Continual Test-Time Adaptation

CIRSeg:基于无源持续测试时间适应的粗到细强度鲁棒肝脏分割
Xu, Ruoshi, Gao, Mingqi, Luo, Shengda, Chen, Jingkun
Abstract
Reliable liver segmentation in contrast-enhanced MRI is essential for quantitative hepatic assessment, treatment planning, and longitudinal disease monitoring. However, limited annotated data and scanner- or vendor-dependent intensity variations can cause overfitting and poor generalization to unseen acquisition domains. Moreover, simultaneously achieving robust global localization and precise boundary delineation remains challenging, while predictions may contain isolated false-positive regions outside the main liver component. To address these challenges, we propose CIRSeg, a coarse-to-fine, intensity-robust liver segmentation framework based on nnU-Netv2. CIRSeg combines 3D CutMix with stochastic intensity transfer using either Nyul augmentation or histogram matching to improve robustness to heterogeneous MRI intensities. Its cascaded architecture decouples low-resolution anatomical localization from full-resolution boundary refinement. At inference, source-free test-time adaptation based on confidence-filtered predictions and probability-prior regularization further improves robustness to out-of-distribution inputs. As a final deterministic post-processing step, largest connected component filtering removes isolated false-positive regions. On the CARE 2026 test set, CIRSeg achieves Dice scores of 97.13\% and 97.93\% on the in-domain and unseen-domain subsets, with corresponding HD95 values of 20.18 mm and 11.30 mm, respectively. These results demonstrate consistently accurate segmentation across both in-domain and unseen acquisition settings. The code is available at https://github.com/jingkunchen/MICCAI_CARE_2026

UltraWorld: Learning Interactive Ultrasound World Models from Untracked Clinical Videos with Acoustic Sampling Map

超世界:从未跟踪的临床视频中学习交互式超声世界模型与声学采样图
Yang, Keke, Wang, Erqi, Guan, Sainan, Ren, Hongliang
Abstract
World models can enable autonomous ultrasound scanning by predicting the outcomes of probe motions from local observations. Learning this action--observation relationship typically relies on synchronized video--pose pairs, which are costly to collect at scale and largely unavailable in routine clinical recordings. Reliable action following further requires modeling ultrasound's cross-sectional sampling geometry. We present UltraWorld, a self-distillation recipe that transfers priors from clinical ultrasound videos into interactive world models without real action annotations. Starting from clinical videos, we adapt a video foundation model into an ultrasound generator conditioned on reference images and anatomical masks. Anatomical masks sampled along programmable trajectories through 3D anatomy provide spatial guidance for synthesizing action--video pairs. We then use these synthetic pairs to self-distill the generator into a world model that predicts future observations from local observations and actions, without requiring anatomical masks or other 3D assets at inference time. To further improve action following, we introduce the Acoustic Sampling Map (AsMap), which represents probe poses and imaging settings as pixel-wise 3D sampling positions, beam directions, and depths. Experiments demonstrate improved prediction fidelity and action following. Across nine simulated closed-loop local planning episodes, UltraWorld reduces the mean final distance to the goal and orientation error by 29\% and 38\%, respectively, compared with visual servoing.

Counterfactual Route Optimization for Gaussian Head Avatar Modeling

高斯头部虚拟形象建模的反事实路径优化
Zhang, Shikun, Li, Yong, Wang, Yiqun, Ke, Qiuhong, Chen, Cunjian
Abstract
Head avatar modeling requires jointly optimizing multiple objectives with different dominant effects on geometry, appearance, and cross-view consistency. However, their relative effectiveness varies across training states, while existing pipelines typically rely on fixed loss weights or handcrafted stage-wise schedules. A central challenge is therefore to identify which optimization direction is more beneficial at each training state. We propose a counterfactual route optimization framework for Gaussian head avatar modeling, which characterizes state-dependent optimization preference from the realized effects of alternative updates rather than predefined heuristic weighting. Starting from the same training state, we perform short-horizon route-restricted lookahead over geometry, appearance, and joint update routes and evaluate their outcomes under a unified utility. The resulting counterfactual evidence is factorized into a geometry--appearance preference and a residual joint advantage, separately capturing the relative preference between individual update directions and the additional benefit of coordinated optimization. We further amortize this offline evidence into a lightweight controller that directly estimates the current optimization preference and applies bounded modulation to the training objectives during full avatar optimization. Experiments on the NeRSemble dataset validate the effectiveness of the proposed design, consistently outperforming existing methods while preserving clearer local facial structures and finer details.

Beyond Masks and Trajectories: Flow-Guided Latent Action Injection for Stable Surgical Video Generation

超越掩膜与轨迹:基于流引导的潜在动作注入用于稳定的外科视频生成
Qin, Tsz-Yui, Zhou, Siyu, Tang, Chi-Keung, Nie, Yuxiang, Yang, Shu
Abstract
Surgical video generation holds substantial potential for surgical education, simulation, and data augmentation, yet generating surgical videos with realistic and clinically plausible motion remains challenging. Most existing methods rely on auxiliary conditions, such as masks, trajectories, depth, or reference videos, to achieve visually plausible synthesis. Yet, these auxiliary conditions typically require additional manual annotation or specialized acquisition, making it difficult to scale such methods beyond small, curated datasets. This motivates the need for a reference-free architecture capable of generating high-quality surgical video without requiring auxiliary visual conditions at inference time. We propose FLAIR, a Flow-guided LatentAction Injection framework for Reference-free surgical video generation. FLAIR learns action priors from optical flow of real surgical videos, dynamically predicts corresponding latent action representation from an input prompt, and injects it into a frozen base model to generate surgical videos with improved action consistency. We further construct SurgActionClip-30K, the first large-scale surgical vision dataset comprising action-centric segmented clips and structured caption labels, addressing the persistent lack of fine-grained, action-centric surgical datasets. Lastly, we introduce SurgMetrics, the first surgical domain-specific evaluation metrics for quantifying the quality of generated surgical videos, addressing the persistent absence of clinically grounded evaluation standards in this domain. Extensive experiments demonstrate that FLAIR enables generating high-quality surgical videos using text-only inference without auxiliary conditions, and validation in SurgMetrics demonstrates its strength in alignment with human perception compared to traditional metrics.

DisParQ: Self-Supervised Part Concepts for Interpretable Vision Foundation Models

DisParQ:用于可解释视觉基础模型的自监督部分概念
Pardyl, Adam, Gairola, Siddhartha, Rao, Sukrut, Wróbel, Adam, Zieliński, Bartosz, Schiele, Bernt, Rymarczyk, Dawid
Abstract
Concept-based vision models represent images through an intermediate layer of human-inspectable concepts, so what a model relies on can be traced to those concepts. However, those models are often limited to fixed categories or depend on language to define their concepts. We introduce DisParQ (Discrete Parts with Quantized attributes), a method that learns spatially grounded, discrete concept representations from a powerful frozen vision-only self-supervised backbone. It requires no class labels and no language supervision. Each image patch is assigned to exactly one concept from a learnable prototype dictionary, and only a sparse subset of concepts may activate per image. To capture how each concept varies across images (e.g., the type of a "wheel"), we learn continuous residuals alongside the concepts and then quantize them into discrete attributes. A spatial decoder reconstructs the backbone's representation from the concepts and attributes alone, so successful reconstruction means that the discrete representation preserves the backbone's information. We evaluate DisParQ across seven datasets, from general recognition (ImageNet, PartImageNet, Places) to fine-grained benchmarks (CUB, Cars, Dogs, Flowers). We show that DisParQ closely matches its frozen DINOv2 teacher on ImageNet linear probing (83.2% top-1), achieves higher concept consistency than language-aligned models, remains competitive on fine-grained recognition, and enables cross-category part-based retrieval.

基于概念的视觉模型通过一层人类可检视的概念中介来表示图像,因此模型所依赖的内容可以追溯到这些概念。然而,这些模型通常局限于固定的类别或依赖语言来定义其概念。我们提出了DisParQ(离散部分与量化属性),一种从强大的冻结视觉自监督骨干网络中学习空间定位的离散概念表示的方法。它不需要类别标签和语言监督。每个图像块被分配给可学习原型字典中的一个概念,并且每个图像可能仅激活一小部分概念。为了捕捉每个概念在不同图像中的变化(例如,“轮子”的类型),我们在学习概念的同时学习连续残差,然后将其量化为离散属性。空间解码器仅根据概念和属性重建骨干网络的表示,因此成功的重建意味着离散表示保留了骨干网络的信息。我们在七个数据集上评估DisParQ,从一般识别(ImageNet、PartImageNet、Places)到细粒度基准(CUB、Cars、Dogs、Flowers)。我们展示了DisParQ在ImageNet线性探测中与其冻结的DINOv2教师模型(83.2% top-1)紧密匹配,获得比语言对齐模型更高的概念一致性,在细粒度识别中保持竞争力,并实现跨类别的基于部分的检索。

Concentration, Not Uncertainty: Why Targeted Synthetic Data Doesn't Help Camouflaged Object Detection

集中,而非不确定性:为何针对性合成数据对伪装物体检测无益
Dobhal, Akshat, Singh, Sanjay
Abstract
Camouflaged object detection requires pixel-accurate masks, but obtaining such annotations is slow and costly, making synthetic training images an attractive alternative. Under a fixed generation budget, however, it remains unclear which real-image regions to target for synthetic data generation. We study an uncertainty-guided generation strategy that clusters the unlabelled real images, identifies clusters on which the model is least certain, allocates synthetic generation toward those clusters, and iteratively retrains the model. Across 103 training runs, uncertainty-based targeting does not outperform random allocation. Five independent controls further show that this null result is not an artifact: targeted training sets are measurably different from random sets, but the difference is explained by concentrating the generation budget rather than by where uncertainty is concentrated, as every concentration rule we test reproduces the effect and, on boundary accuracy, so does aiming at the clusters the model was most certain about. Separately, we find substantial data contamination in CHAMELEON, with 50 of its 76 images duplicated from training data despite the standard overlap check reporting zero overlap. Together, these results show that, under a fixed synthetic-data budget, budget concentration, not uncertainty-based targeting, accounts for the observed training-set effects.

Abstract
Generative 3D Gaussian head avatars provide high-quality, efficient rendering, but synthesising the Gaussian representation remains computationally expensive, limiting deployment on resource-constrained and edge devices. We introduce an efficient generator architecture for unconditional 3D Gaussian head synthesis, based on a parameter-efficient synthesis block and depth-wise separable convolutions while retaining style-based conditioning. Our architecture reduces generator complexity without requiring model compression or quantisation. Compared with the baseline model, our approach reduces FLOPs by 94%, parameter count by 70%, and model size by 81%, while maintaining competitive generation quality. We further demonstrate practical CPU inference and browser-based execution on mobile devices using ONNX Runtime, enabling 3D Gaussian avatar synthesis without dedicated GPU hardware or application-specific software. In addition to conventional image-quality metrics, we evaluate multi-view consistency, training cost, and deployment performance. Code, trained models, and evaluation tools will be released publicly.

Abstract
Dense visual text requires image generators to reproduce long strings across multiple regions with correct placement and legibility. As short-string rendering improves, evaluation must test sustained performance across more demanding scenes. We introduce UltraText Bench, a bilingual benchmark for prompt-only generation of dense visual text. It contains 432 prompts spanning 24 real-world scene categories and three difficulty levels, split equally between English and Chinese. Each human-reviewed prompt supplies exact strings for four to twelve text regions, paired with structured references for their content, placement, and visual attributes. We use the Q-Judger vision-language model to assess each image against the complete reference, reporting text fidelity, text clarity, spatial quality, and scene quality. Across 24 model configurations, these dimensions reveal different strengths: Z-Image-Turbo gains 3.81 clarity points over Z-Image-Base while losing 14.76 fidelity points under the reported settings. Performance also varies with workload; Qwen-Image-2512's English composite falls from 86.50 at L1 to 42.86 at L3. Ten participants took part in human evaluation of the automatic scores.

MOTIF: Person-of-Interest Deepfake Detection Beyond 3DMM Coefficients

MOTIF:超越3DMM系数的人物深度伪造检测
Affatato, Giovanni, Mandelli, Sara, Bestagini, Paolo, Tubaro, Stefano
Abstract
Video deepfakes targeting a specific individual, the Person-of-Interest (POI), are the most harmful ones, and, since a public figure is abundantly recorded, a detector can be built from genuine footage of that individual. Such detectors commonly describe a subject through a 3D Morphable Model (3DMM) and adopt its coefficients as a whole, so which part of that description carries the signal has never been measured. We dissect it, holding the encoder, the training corpus and the enrollment protocol fixed and varying only what the encoder observes. The groups of coefficients prove largely redundant, since the shape block alone recovers almost all the accuracy of the full vector, and their temporal evolution contributes a real but bounded amount. We further show that the dense surface the same fit returns, which these detectors discard, carries identity information that the coefficients do not, and that it helps precisely where they are weakest. We assemble the best configuration into MOTIF, a visual-only detector trained on real videos only, with no manipulated video and no POI-specific data. It improves on both state-of-the-art POI detectors in every dataset and manipulation of our benchmark and at two quality levels. Our experimental code will be released at https://github.com/polimi-ispl/MOTIF.

ORCA: Hunting Compositional Failures in Text-to-Image Diffusion

ORCA:在文本到图像扩散中捕捉组合失败
Hemmat, Arshia, Vahidi, Amirhossein, Shidani, Amitis, Sanian, Mohammad Vali, Asadollahzadeh, Hesam, Parast, Aryan Yazdan, Lotfollahi, Mohammad
Abstract
Text-to-image diffusion models fail predictably on compositional prompts: attributes bind to the wrong objects, spatial relations invert, and multi-object scenes lose count. Recent architectures already augment CLIP with a T5 encoder precisely because CLIP's contrastive embedding loses compositional structure, yet these failures persist. We argue the binding problem is therefore not one of missing information but of misaligned information: a text encoder preserves compositional structure, but in a representation space shaped by language modelling rather than vision, and the denoising objective does not directly reward aligning the two. We show this correspondence can be supplied as an explicit training signal, that the relevant cross-modal information is concentrated in a low-rank subspace of self-supervised visual features, and that supplying it can be folded into diffusion training as a single auxiliary loss. Our method, ORCA (Orthogonal Residual Compositional Alignment), aligns the latent of a diffusion transformer with a low-rank target derived from a frozen visual encoder, through a predictor whose orthogonal basis is parameterised by a learned residual between T5 and CLIP embeddings, which provides a prompt-dependent signal for selecting the visual readout subspace. We prove that the cross-modal information recoverable at a given rank is bounded by the spectral mass of the visual encoder's covariance in the top components. Across three diffusion-transformer backbones (DiT-B/2, DiT-L/2, U-ViT-L), ORCA improves FID and GenEval over both vanilla and REPA baselines at zero inference-time cost; on DiT-L/2 it reaches FID 16.65 and GenEval 0.291 at 200K steps, exceeding the strongest 400K baseline at half the training cost, with the largest gains concentrated on attribute binding, spatial relations, and multi-object prompts.

Hard, Yet Reducible: Controlled Forward Transfer for Synthetic Degradation Curation

困难但可简化:合成降解策划的受控前向转移
He, Chunming, Zhou, Kailai, Zuo, Jiaming, Liu, Hanqi, Xiao, Fengyang, Pang, Youwei, Liu, Xiaofeng, Lin, Weisi, Zhao, Xiaoqi
Abstract
Selecting synthetic degradations for dense prediction requires an estimate of their training utility, the generalization gain they bring under a finite training budget. Clean and degraded twins share content and labels, suggesting a score based on how much short training reduces the excess error caused by degradation. However, this gap can also shrink when clean performance deteriorates. Measuring the improvement on degraded images alone avoids that confound, but it still credits progress that the same amount of clean training would have produced. We propose the \textbf{controlled Reducible Degradation Gap} (cRDG) for regions defined by degradation type and severity. From a common checkpoint, cRDG runs two budget-matched probes that differ only in one augmentation slot, which holds either a synthetic degradation or a clean augmentation. The score is the gain on held-out degraded images relative to the clean-control probe. Clean harm is a separate feasibility constraint. cRDG reveals a correctable severity band in which training on the degradation yields high controlled gain under the available budget, and the band moves with the predictor, the starting checkpoint, and the training budget. \textbf{Curation of Reducible Bands} (\method) uses cRDG to select synthetic data without changing the predictor. On semantic segmentation and salient object detection, \method{} improves representative predictors under matched synthetic-data budgets and training schedules, extends to existing data-generation pipelines, and preserves clean performance. Code and supporting materials will be publicly released.

DeltaSplat: Iterative Gaussian Refinement for Pose-Free Feed-Forward 3D Gaussian Splatting

DeltaSplat:无姿态前馈3D高斯点云的迭代高斯精细化
Park, Chanung, Song, Seunghyeon, Lee, Joo Chan, Park, Eunbyung, Ko, Jong Hwan
Abstract
Pose-free feed-forward 3D Gaussian Splatting (3DGS) reconstructs a scene from sparse, unposed images in a single network pass, removing the need for camera calibration and per-scene optimization. However, camera estimation errors propagate into the predicted Gaussians and compound the geometric and photometric inaccuracies of single-pass prediction. To correct these errors, we introduce DeltaSplat, a lightweight Gaussian refinement module for pose-free feed-forward 3DGS. It iteratively renders the current Gaussians at the input context views and predicts per-Gaussian updates from the resulting residuals. A 2D residual alone, however, underdetermines the 3D correction. DeltaSplat therefore conditions each update on per-pixel Pl\"ucker rays and rendered depth as a soft geometric prior. A dual-branch convolutional mixer efficiently encodes these inputs, and per-attribute heads decode the fused features into position, opacity, and color updates. The module adds only ~2.2% parameters to the backbone and remains fully feed-forward at inference. On DL3DV, DeltaSplat reaches 26.64 dB PSNR in the pose-free setting, improving its state-of-the-art backbone by 1.75 dB and surpassing even baselines supplied with ground-truth cameras; consistent gains hold across 6-24 views and all camera regimes.

无姿态前馈3D高斯点云(3DGS)通过单次网络传递从稀疏的无姿态图像中重建场景,消除了对相机标定和每个场景优化的需求。然而,相机估计误差会传播到预测的高斯分布中,并加剧单次预测的几何和光度不准确性。为了解决这些误差,我们引入了DeltaSplat,一个轻量级的高斯精细化模块,适用于无姿态前馈3DGS。该模块在输入上下文视图中迭代渲染当前高斯,并从结果残差中预测每个高斯的更新。然而,仅依赖2D残差不足以确定3D修正。因此,DeltaSplat将每个更新条件化为每个像素的Plücker光线和渲染深度,作为一种软几何先验。一个双分支卷积混合器有效地编码这些输入,而每个属性头则将融合特征解码为位置、不透明度和颜色更新。该模块仅为主干网络增加约2.2%的参数,并在推理时保持完全前馈。在DL3DV数据集上,DeltaSplat在无姿态设置中达到了26.64 dB的PSNR,较其最先进的主干网络提高了1.75 dB,甚至超越了使用真实相机的基线;在6-24个视图和所有相机模式下,均保持一致的性能提升。

DeepTopoClustering: Unsupervised Derivation of Surface Process Taxonomy from 4D Point Clouds for Topographic Monitoring

DeepTopoClustering:从4D点云中无监督推导地表过程分类法以进行地形监测
Wang, Jiapan, Hulskemper, Daan, Letard, Mathilde, Lindenbergh, Roderik, Anders, Katharina
Abstract
4D point clouds acquired by permanent laser scanning (PLS) enable accurate high-frequency monitoring of surface change in dynamic topographic environments. However, existing methods remain limited in organizing detected surface activities into meaningful process types. We propose DeepTopoClustering (DTC), an unsupervised framework for deriving a hierarchical process taxonomy from object-based surface activities, so-called 4D objects-by-change (4D-OBCs). We transform each 4D-OBC into a GeoMorphogram, a distributional sequence representing the temporal evolution of topographic change within a spatially bounded surface activity. A convolutional autoencoder learns latent embeddings from GeoMorphograms, which are jointly optimized using a hierarchical deep clustering objective to organize surface activities into a hierarchy. We evaluate the learned hierarchy using expert annotations on two 4D datasets of sandy beach sites and their combination. DTC with GeoMorphograms achieves the highest agreement with expert judgment at the taxonomy level comprising eight major process types ($F_1=0.78$, match accuracy $=0.92$), outperforming dimensionality reduction and conventional flat clustering. The learned taxonomy separates major erosion- and deposition-dominated activities and distinguishes finer subtypes based on change magnitude, duration, compactness, and temporal evolution. DTC thus provides a scalable and interpretable route from 4D change detection to a data-driven, expert-supported surface process taxonomy, advancing automated knowledge derivation for understanding surface dynamics in topographic monitoring.

Global Average Precision for Representation Learning

用于表示学习的全局平均精度
Psomas, Bill, Mahdi, Mohammad, Thomas, Michalis, Paudel, Danda Pani, Tolias, Giorgos, Kordopatis-Zilos, Giorgos
Abstract
Standard information retrieval metrics, such as mean Average Precision (mAP), assess performance one query at a time, based on how the similarities between a query and its positives compare against those with its negatives. The same holds for common representation learning losses, such as InfoNCE and per-query AP surrogates. None of them considers whether similarities are comparable across queries, which any system with a single decision threshold relies on. Global Average Precision (gAP) does, by ranking all query-candidate pairs in one list and computing a single AP. We introduce gSAP, a differentiable surrogate of gAP. It needs only a similarity matrix and a binary matrix marking the positive pairs, the same input as existing losses, so it is a drop-in replacement for them and agnostic to the encoder, the modality, and the source of supervision. Since it considers all possible pairwise comparisons in the batch jointly, it also remains trainable at low temperatures, a regime where per-query surrogates run out of gradient. Swapping it into established recipes improves supervised metric learning, cross-modal alignment, and self-supervised pretraining, where, to our knowledge, it is the first ranking loss to replace the community standard InfoNCE in the latter two. Its similarities are more consistent across queries, which drives the gains under a universal threshold. gSAP retrieves up to four times as many positive pairs as the strongest AP surrogate at the same precision, and it degrades the least when queries with no positives in the database are added. Beyond thresholding, models trained with gSAP also learn better representations, with higher transfer, $k$NN and zero-shot classification accuracy.

标准的信息检索指标,如平均精度均值(mean Average Precision, mAP),是通过比较查询与其正样本之间的相似性与查询与其负样本之间的相似性来逐个查询评估性能的。常见的表示学习损失,如InfoNCE和逐查询平均精度(per-query AP)替代品也是如此。它们都没有考虑不同查询之间的相似性是否可比,而任何依赖单一决策阈值的系统都需要这一点。全局平均精度(Global Average Precision, gAP)通过将所有查询-候选对排名在一个列表中并计算单一的平均精度(AP)来解决这个问题。我们引入了gSAP,这是gAP的一个可微分替代品。它只需要一个相似性矩阵和一个标记正样本对的二进制矩阵,这与现有损失的输入相同,因此可以作为它们的直接替代,并且与编码器、模态和监督源无关。由于它联合考虑批次中的所有可能成对比较,因此在低温度下仍然可以训练,而在此情况下,逐查询替代品会失去梯度。将其替换到现有方法中可以改善监督度量学习、跨模态对齐和自监督预训练。在我们所知的范围内,它是第一个在后两者中替代社区标准InfoNCE的排名损失。它在不同查询之间的相似性更加一致,这推动了在通用阈值下的增益。gSAP在相同精度下检索的正样本对数量是最强AP替代品的四倍,并且在添加没有正样本的查询时降级最小。超越阈值,使用gSAP训练的模型还学习到了更好的表示,具有更高的迁移能力、$k$NN和零样本分类准确率。

Bringing BNNs to Fast Event Processing

将二进制神经网络应用于快速事件处理
Longour, Paul, Moreau, Julien, Davoine, Franck
Abstract
Binary Neural Networks (BNNs) enable efficient deep learning deployment on resource constrained devices with weights and activations compressed to one bit, substantially reducing model size and inference cost. Event cameras offer complementary advantages, including low latency, high dynamic range, and low power consumption, by capturing asynchronous streams of events rather than dense image frames. Despite their shared emphasis on efficiency, the combination of these technologies remains largely unexplored. This work aims at adapting and evaluating modern deep BNN architectures on event data. We also show that cross-modal pretraining from RGB data can improve the classification accuracy of BNNs on neuromorphic datasets. We introduce the Polar-wise Binary Event Volume (PBEV), a binary representation that enables event-camera data to be processed directly by BNNs and represents a step toward fully binarized event-based vision systems. Best evaluated BNN on N-Caltech101 classification benchmarks shows 90.58% accuracy with 7.5x less operations than their full-precision counterparts.

SANet: Selective Attention Network for Infrared Small Target Detection

SANet:用于红外小目标检测的选择性注意力网络
Zhang, Yingmei, Bao, Wangtao, Xiao, Qin, Yang, Yong, Wan, Weiguo, Luo, Yitao, Zou, Xueting, Zhang, Lei
Abstract
Infrared small target detection aims to accurately identify and locate dim targets in complex backgrounds and supports applications such as maritime surveillance and military search and rescue. However, the small size and weak contrast of infrared targets make it difficult to balance detection accuracy and false alarms. This paper proposes a selective attention network (SANet) for infrared small target detection. A dual-path semantic-aware module combines standard and pinwheel-shaped convolutions to preserve local spatial consistency and capture broader contextual information. Spatial and channel attention further refine the features and improve target-background discrimination. To address the limitations of static skip connections in U-Net, a selective attention fusion module adaptively integrates features across scales using spatially varying weights. It selectively enhances salient regions and improves discrimination between true targets and false alarms. Experiments on three public benchmarks, NUAA-SIRST, IRSTD-1K, and NUDT-SIRST, show that SANet achieves competitive performance in intersection over union (IoU), normalized IoU, detection probability, and false alarm rate. Its IoU exceeds that of the second-best method by 1.93, 4.32, and 2.21 percentage points, respectively. These results support the effectiveness of SANet in dim-target perception, discriminative feature representation, and background suppression.

FedSSMCoOp: SSM Encoders for light-weight Federated Prompt Learning for Few-shot Classification

FedSSMCoOp:轻量级联邦提示学习的SSM编码器用于少样本分类
Das, Ankita, Parthasarathy, Ambarish, Channappayya, Sumohana S., Mohan, C. Krishna
Abstract
Vision-Language Models (VLMs) have shown strong performance across a wide range of downstream vision tasks, thanks to the complementary information contained in the respective domains. Despite the performance gains, most of these approaches rely on aligning these domains using the cosine similarity metric, which fails to capture token-level structure and cross-modal interactions prior to the classification stage. This is especially critical in biomedical applications under federated constraints, where data sharing is restricted, labeled data is scarce at each site, and it differs widely across institutions, leading to substantial statistical heterogeneity. To overcome this issue, we propose FedSSMCoOp, a federated few-shot image classification framework that enables multimodal learning while preserving data privacy. With the help of the SSM-based Vision Mamba and Cross Mamba blocks, and by optimizing only the soft-prompt and communication-prompt updates in the federated setting, the framework prioritizes both computation and performance. Importantly, this eliminates the need to use an external Large Language Model (LLM) for feature alignment. The framework is further trained and evaluated on various biomedical image datasets, and its performance is assessed. The proposed framework delivers stable performance relative to the baselines and is, on average, 1.96 times lighter. The corresponding script will be made available soon.

视觉-语言模型(VLMs)在广泛的下游视觉任务中表现出色,这得益于各自领域中包含的互补信息。尽管性能有所提升,但大多数方法依赖于使用余弦相似度度量来对齐这些领域,这未能在分类阶段之前捕捉到标记级别的结构和跨模态交互。这在联邦约束下的生物医学应用中尤为重要,因为数据共享受到限制,各个站点的标记数据稀缺,并且在不同机构之间差异很大,导致显著的统计异质性。为了解决这一问题,我们提出了FedSSMCoOp,一个联邦少样本图像分类框架,能够在保护数据隐私的同时实现多模态学习。借助基于SSM的Vision Mamba和Cross Mamba模块,并仅在联邦环境中优化软提示和通信提示的更新,该框架优先考虑计算和性能。重要的是,这消除了使用外部大型语言模型(LLM)进行特征对齐的必要性。该框架进一步在各种生物医学图像数据集上进行训练和评估,并对其性能进行评估。所提出的框架相对于基线提供了稳定的性能,且平均轻量级为1.96倍。相关脚本将很快提供。

Do Generative Priors Align with Human Naturalness Perception?

生成先验与人类自然感知的对齐程度如何?
Fukiage, Taiki
Abstract
Visual generative models are trained to capture the probability distributions of natural images, yet whether their native priors reflect the regularities governing human perception of image naturalness remains an open question. Here, we probe these priors through native prediction errors across 25 open image and video generators. Because raw single-image losses are dominated by scene content and visual complexity, we evaluate directional loss differences using content-preserving, paired relational interventions that selectively disrupt facial configurations or physical illumination consistency while limiting changes in low-level image statistics. Across both domains, these loss differences reproduce human-like selective sensitivities and tolerances, capturing the classic Thatcher effect on faces and shape-dependent responses to illumination inconsistencies. Notably, these loss differences reliably track continuous gradations of human naturalness judgments across individual stimulus pairs (peaking at $r = .84$ on faces and $.64$ on physical scenes) and retain unique human-aligned signals even after controlling for feature distances from frozen vision encoders and standard image quality metrics. We also find that while overall sensitivity to these violations broadly covaries with human alignment across models, the two systematically decouple along denoising schedules, with alignment peaking earlier than sensitivity, revealing that human-like naturalness judgments dissociate from generic violation detection. Together, these findings demonstrate that learning visual distributions yields generative loss landscapes that capture distinct aspects of human naturalness perception.

视觉生成模型被训练以捕捉自然图像的概率分布,但它们的固有先验是否反映了支配人类图像自然感知的规律仍然是一个未解之谜。在此,我们通过对25个开放图像和视频生成器的固有预测误差进行探讨。由于原始单图像损失主要受场景内容和视觉复杂度的支配,我们使用保持内容的配对关系干预来评估方向性损失差异,这些干预选择性地扰乱面部配置或物理照明一致性,同时限制低级图像统计特征的变化。在这两个领域中,这些损失差异再现了类似人类的选择性敏感性和容忍度,捕捉到经典的撒切尔效应以及对照明不一致性的形状依赖反应。值得注意的是,这些损失差异可靠地追踪了个体刺激对之间人类自然感知判断的连续梯度(在面部图像上达到$r = .84$,在物理场景上达到$.64$),并在控制了与冻结视觉编码器的特征距离和标准图像质量指标后,仍然保留了独特的人类对齐信号。我们还发现,尽管对这些违规行为的整体敏感性在模型之间广泛变化与人类对齐相关,但两者在去噪调度中系统性地解耦,且对齐在敏感性之前达到峰值,揭示了类似人类的自然感知判断与通用违规检测之间的分离。综上所述,这些发现表明,学习视觉分布产生的生成损失景观捕捉了人类自然感知的不同方面。

Purifying Backdoored Large Vision-Language Models by Removing Hijacked Directions

通过去除劫持方向净化后门大型视觉-语言模型
Yang, Bojun, Zhou, Haochen, Zhang, Zhifang, Wang, Haobo, Li, Songze, Feng, Lei
Abstract
Large vision-language models (LVLMs) are increasingly deployed in safety-critical applications, yet they remain vulnerable to backdoor attacks. Defending against such attacks remains costly, as existing methods require either extensive retraining on clean data or per-query intervention at inference time. To address this limitation, we propose OrthoPurify, a more efficient method to purify backdoored model weights via one-step orthogonal projection. Specifically, through structural analysis of backdoor weight updates, we find that the backdoor is encoded by diverting a small number of weight update directions from task adaptation to backdoor shortcut encoding, a phenomenon we term direction hijacking. However, identifying these hijacked directions requires a benign reference model, which is typically inaccessible to the defender. We show that a pseudo-benign model, obtained by fine-tuning the pretrained weights on only a small set of clean samples, provides a sufficient approximation, as the dominant update directions stabilize within the first few gradient steps. OrthoPurify uses this pseudo-benign reference to isolate the hijacked directions and removes them through a single projection on the weight update. Extensive experiments show that OrthoPurify reduces the attack success rate to near zero while preserving the original performance across diverse benchmarks, without retraining the backdoored model or introducing inference-time overhead. Our code is publicly available at https://github.com/womeimingzi/OrthoPurify.

大型视觉-语言模型(LVLMs)越来越多地应用于安全关键的场景,但它们仍然容易受到后门攻击。防御此类攻击的成本依然高昂,因为现有方法要么需要在干净数据上进行广泛的重新训练,要么在推理时进行逐查询干预。为了解决这一限制,我们提出了 OrthoPurify,一种通过一步正交投影来净化后门模型权重的更高效的方法。具体而言,通过对后门权重更新的结构分析,我们发现后门是通过将少量权重更新方向从任务适应转移到后门捷径编码来编码的,这一现象我们称之为方向劫持。然而,识别这些劫持方向需要一个良性参考模型,而该模型通常对防御者不可用。我们表明,通过仅在一小部分干净样本上微调预训练权重获得的伪良性模型提供了足够的近似,因为主导更新方向在前几步梯度更新中会稳定。OrthoPurify 使用这个伪良性参考来隔离劫持方向,并通过对权重更新进行单次投影将其去除。大量实验表明,OrthoPurify 将攻击成功率降低到接近零,同时在各种基准测试中保持原始性能,无需重新训练后门模型或引入推理时的开销。我们的代码公开可用,地址为 https://github.com/womeimingzi/OrthoPurify。

MSU Team at the Explainable Deepfake Detection Challenge 2026: Grounded Artifact Evidence for Deepfake Detection

MSU团队在2026年可解释深度伪造检测挑战中的表现:基于可见伪证的深度伪造检测
Filippov, Artem, Gushchin, Aleksandr, Koltsov, Kirill, Vatolin, Dmitriy, Antsiferova, Anastasia
Abstract
Recent advances in generative image models have made many manipulated images highly realistic, raising the need for detectors that are not only accurate but also able to provide visual evidence for their decisions. In this paper, we present our solution to the Explainable Deepfake Detection Challenge [2] on the XPlainVerse dataset [1], where systems are required to predict whether an image is real or fake and generate both complex and simple explanations grounded in visible forensic cues. Our method follows a modular detection-and-explanation design. For the real/fake decision, we build a multi-backbone detector that combines several DINOv3 models with Mesorch manipulation-localization features, bringing together pretrained visual representations, DCT-aware cues, and multi-scale forensic information. To inject explanation evidence into the detector, we use a Grounding-DINO-based pseudo-mask generation pipeline that converts local artifact descriptions from training explanations into weak patch- level supervision for an Artifact Evidence Map. We further introduce a local patch-level contrastive objective that separates artifact and authenticity evidence in the detector feature space without requiring paired images or pixel-level manipulation masks. For language output, we use class-conditional Qwen3-VL models to generate complex explanations for fake and real predictions, followed by a GRPO-optimized text simplification model. The proposed methods were trained and evaluated on the challenge subset of XPlainVerse. On the full test split, our submission achieves 0.9349 detection accuracy, 0.5571 explanation score, and a 0.7456 final challenge score.

Perceptually Aligned Evaluation of Style Transfer

感知对齐的风格迁移评估
Deng, Yang, Ioannou, Eleftherios, Mould, David, Maddock, Steve, Rosin, Paul L., Lai, Yu-Kun
Abstract
Style transfer lacks a reliable evaluation standard: ground truth is inherently ill-defined, and existing automatic metrics often fail to reflect human preference. This paper introduces ASTRA (Assessment of Style TRansfer Algorithms), an approach for automatic evaluation of style transfer algorithms; it contains two components, ASTRA-Data and ASTRA-Score. ASTRA-Data consists of a benchmark image set of content and style references, a collection of style transfer results generated on the benchmark set, and user study data capturing human judgements through a two-stage pairwise comparison protocol. From these annotations, we derive ranking-based ground truth for content preservation, style fidelity, and overall preference. Based on ASTRA-Data, we construct ASTRA-Score, a learnt evaluator that predicts preference-aligned scores from content-style-stylization image triplets, enabling automatic and scalable evaluation of new models applied to the benchmark set. Experimental results demonstrate that ASTRA-Score achieves substantially higher correlation with human rankings compared to prior metrics. Overall, ASTRA establishes a robust mechanism for standardised evaluation of style transfer methods.

In the present article, after reviewing the literature related to watershed segmentation, we present a detailed end-to-end pipeline of algorithms to compute (hierarchical) watershed segmentations, starting from the computation of graph-based image representations, up to the computation of connected components of the final (hierarchical) segmentation. We consider the several variations of watersheds, including their supervised and unsupervised versions, and the various ways of computing seeds, to name a few. For the first time, we bring together all these watershed notions and algorithms in a compact and understandable way. We aim at providing a reference for those interested in employing and reimplementing the watershed segmentation framework for their task at hand.

Scalable Patch-Level Self-Supervised Learning

可扩展的补丁级自监督学习
Seitzer, Maximilian, Trivigno, Gabriele, Vobecký, Antonín, Yi, Seungeun, Oquab, Maxime, Vo, Huy V., Siméoni, Oriane, Bojanowski, Piotr
Abstract
Self-supervised learning (SSL) at scale produces powerful visual representations. However, most scalable SSL methods rely on ad hoc combinations of multiple objectives and stabilization mechanisms. Taking a step back, we ask if we can design a high-performing, yet principled SSL algorithm. Starting from the multi-view assumption, stipulating that task-relevant content is captured by the information common to different views, we construct an information-theoretic objective decomposing into interpretable terms. This derivation yields JEM, a student-teacher method that learns by aligning corresponding patch representations across views, explicitly regularized by information and structure preservation losses. JEM trains stably from 300M to 7B parameters, and, to our knowledge, is the first latent-space patch-level method demonstrated at 7B scale. Across all scales, JEM reaches strong performance on both global and dense probing tasks, on segmentation benchmarks consistently surpassing the DINOv2 algorithm, an influential foundation for today's strongest visual SSL methods. Notably, at 7B parameters, it exceeds the performance of DINOv3 on panoptic segmentation, despite being trained on $12\times$ less data without refinement stages. These results demonstrate that we can indeed design an SSL algorithm that learns strong representations, is principled and stable.

大规模自监督学习(SSL)能够生成强大的视觉表征。然而,大多数可扩展的SSL方法依赖于多种目标和稳定机制的临时组合。我们退一步思考,是否可以设计出一种高性能且有原则的SSL算法。基于多视角假设,规定任务相关内容由不同视角间的共同信息捕获,我们构建了一个信息论目标,分解为可解释的项。该推导产生了JEM,一种通过对齐不同视角中的对应补丁表征进行学习的师生方法,明确地通过信息和结构保留损失进行正则化。JEM在从3亿到70亿参数的范围内稳定训练,据我们所知,这是第一个在70亿规模下展示的潜在空间补丁级方法。在所有规模下,JEM在全局和密集探测任务上均表现出色,在分割基准测试中持续超越DINOv2算法,后者是当今最强视觉SSL方法的重要基础。值得注意的是,在70亿参数下,尽管在没有细化阶段的情况下训练的数据量是DINOv3的$12 imes$,但其在全景分割任务上的表现仍超过了DINOv3。这些结果表明,我们确实可以设计出一种学习强大表征的SSL算法,该算法是有原则且稳定的。

AdSpark: A Large-Scale Dataset and Benchmark for Product-Centric Advertisement Video Generation

AdSpark:面向产品的广告视频生成的大规模数据集与基准

Abstract
Product-centric advertisement video generation aims to create promotional videos that preserve fine-grained product identity while presenting selling points through coherent multi-shot narratives. However, this emerging task remains underexplored due to the lack of large-scale advertisement-specific datasets and comprehensive evaluation frameworks. To address this gap, we introduce \textbf{AdSpark}, a large-scale dataset and benchmark for product-centric advertisement video generation, based on data from a major e-commerce platform. \textit{AdSpark-300K} contains approximately 300K reference image--prompt--video triplets, comprising a real-world subset and a synthetic subset. Each sample provides structured advertisement annotations, including product identity annotations, selling-point descriptions, creative plans, and aligned audio scripts, enabling models to learn product preservation and advertisement-oriented visual storytelling. We further propose \textit{AdSpark-Bench}, a diagnostic benchmark that evaluates generated advertisements across six dimensions, including visual quality, product fidelity, instruction adherence, temporal coherence, audio alignment, and advertisement effectiveness. Based on AdSpark-Bench, we evaluate representative models, revealing key challenges in product preservation, multi-shot storytelling, and selling-point visualization. Experiments with AdSpark-300K-finetuned models further validate the effectiveness of our dataset. AdSpark provides a unified dataset and benchmark for future research, and we will release the dataset upon acceptance.

From Pixel to Coding: Evaluating the Figure Reproduction Capabilities of MLLMs

从像素到编码:评估多模态大型语言模型的图形再现能力
Chen, Zijian, Chen, Zhengyu, Liang, Bohan, Deng, Lirong, Zheng, Yushuo, Jiang, Yanwei, Jia, Qi, Zhang, Kaiwei, Zhang, Wenjun, Zhai, Guangtao
Abstract
Multimodal Large Language Models (MLLMs) have demonstrated impressive capabilities in both visual understanding and code generation. However, existing benchmarks typically evaluate these two modalities in isolation, lacking a dedicated assessment of their unification, i.e., how a model can perceive complex visual structures and synthesize them into precise, executable code. Moreover, current visual code generation benchmarks often rely on simplified layouts within single programming environments, falling short of evaluating true unified multimodal reasoning. To bridge this gap, we propose FigCodeBench, a comprehensive framework for rigorously evaluating MLLMs on figure reproduction, integrating multimodal comprehension and generation. We first design a systematic dataset construction pipeline, resulting in a total of 6,194 instances that cover 7 functional categories and 4 types of programming languages. We further categorize figure reproduction into three tiers with visual and code complexity modeling, specifically targeting complex structural reasoning, varying aspect ratios, and dense geometric constraints. We introduce a multi-dimensional evaluation protocol, encompassing visual fidelity and syntactic isomorphism, that aligns highly with the Mean Machine Opinion Score (MMOS) and human preferences. Based on our framework, we conducted extensive experiments on 24 widely used proprietary and open-source MLLMs (e.g., Gemini 3.1 Pro, GPT-5.4, and Kimi-K2.5), where we observed a universal, non-linear performance cliff across different programming languages and difficulty scenarios for all models, and gained several insights, such as the significant metric decline in rigid declarative languages.

多模态大型语言模型(MLLMs)在视觉理解和代码生成方面展现了令人印象深刻的能力。然而,现有的基准测试通常孤立地评估这两种模态,缺乏对其统一性的专门评估,即模型如何感知复杂的视觉结构并将其合成成精确的可执行代码。此外,目前的视觉代码生成基准往往依赖于单一编程环境中的简化布局,未能真正评估统一的多模态推理。为了解决这一问题,我们提出了FigCodeBench,这是一个全面的框架,用于严格评估MLLMs在图形再现方面的能力,整合了多模态理解和生成。我们首先设计了一个系统的数据集构建流程,最终生成了6194个实例,涵盖7个功能类别和4种编程语言类型。我们进一步将图形再现分为三个层次,并对视觉和代码复杂性进行建模,特别针对复杂的结构推理、不同的纵横比以及密集的几何约束。我们引入了一个多维评估协议,涵盖视觉保真度和语法同构性,与平均机器意见分数(MMOS)和人类偏好高度一致。基于我们的框架,我们对24个广泛使用的专有和开源MLLMs(如Gemini 3.1 Pro、GPT-5.4和Kimi-K2.5)进行了广泛实验,观察到所有模型在不同编程语言和难度场景下普遍存在非线性的性能下降,并获得了一些见解,例如在严格的声明性语言中的显著指标下降。

Temporal Residual Bottleneck for Robust Asynchronous Collaborative Perception

用于鲁棒异步协作感知的时间残差瓶颈
Yazgan, Melih, Abouelazm, Ahmed, Zöllner, J. Marius
Abstract
Collaborative perception extends the sensing range of autonomous vehicles, but its performance degrades when shared features arrive stale or incomplete. Most latency-robust methods compensate delayed collaborator features through flow-guided alignment or direct feature transport. In this work, we formulate asynchronous collaborative perception as temporal residual prediction. Our Temporal Residual Bottleneck keeps a deterministic pose-warped collaborator feature as a conservative anchor and uses a $\Delta t$-conditioned xLSTM to extract residual temporal evidence from the available history. A detector-facing residual bottleneck then applies only gated, regularized corrections before ego-side fusion, reducing the risk of overwriting reliable static structure when temporal correspondence is uncertain. Experiments on DAIR-V2X and OPV2V show that our method is especially effective under severe fixed/irregular delays and packet drops. On DAIR-V2X, the reported checkpoint trades a small amount of synchronized peak accuracy for better robustness under stronger communication degradation. Controlled diagnostics further indicate that direct feature transport has oracle headroom but can become unreliable when deployed without accurate correspondence. These results support temporal residual fusion as a practical alternative for asynchronous and incomplete collaborative perception. Code will be publicly released at https://url.fzi.de/8dk38.

协作感知扩展了自动驾驶车辆的感知范围,但当共享特征变得过时或不完整时,其性能会下降。大多数抗延迟方法通过流引导对齐或直接特征传输来补偿延迟的协作特征。在本研究中,我们将异步协作感知形式化为时间残差预测。我们的时间残差瓶颈保持一个确定性的姿态扭曲协作特征作为保守锚点,并使用 $ ext{Δ}t$ 条件的 xLSTM 从可用历史中提取残差时间证据。面向检测器的残差瓶颈在自我侧融合之前仅应用门控的正则化修正,从而降低在时间对应不确定时覆盖可靠静态结构的风险。在 DAIR-V2X 和 OPV2V 上的实验表明,我们的方法在严重的固定/不规则延迟和数据包丢失情况下尤其有效。在 DAIR-V2X 上,报告的检查点在更强的通信退化下以较小的同步峰值精度换取了更好的鲁棒性。控制诊断进一步表明,直接特征传输具有理想的潜力,但在没有准确对应的情况下部署时可能变得不可靠。这些结果支持时间残差融合作为异步和不完整协作感知的实用替代方案。代码将公开发布在 https://url.fzi.de/8dk38。

A Probabilistic Perspective on Wasserstein-Based Evidential Uncertainty for Out-of-Distribution Segmentation

基于Wasserstein的证据不确定性的概率视角:针对分布外分割
Brosch, Arnold, Eldesokey, Abdelrahman, Felsberg, Michael, Maag, Kira
Abstract
Semantic segmentation networks operate on a fixed set of classes and therefore fail when out-of-distribution (OOD) objects appear during deployment, a critical limitation for safety-critical applications such as autonomous driving. Reliably identifying OOD objects requires well-calibrated epistemic uncertainty, yet common softmax-based confidence scores remain overconfident, while Bayesian alternatives such as Monte Carlo dropout or deep ensembles require costly repeated forward passes. Evidential Deep Learning (EDL) offers an efficient alternative by modeling class probabilities as a Dirichlet distribution learned from a single deterministic forward pass. Existing EDL formulations rely on Euclidean objectives that push predictions towards the simplex vertices, encouraging overconfidence rather than preserving uncertainty for unfamiliar inputs. We instead employ Wasserstein-based objectives, which respect the geometry of the probability simplex, and study the influence of the Wasserstein order on segmentation accuracy and OOD detection within a unified evidential framework. We evaluate this framework on a convolutional (DeepLabV3+) and a transformer-based (SegFormer) architecture on the SegmentMeIfYouCan benchmark, including LostAndFound, RoadObstacle21, RoadAnomaly21, and Fishyscapes. Our results show the optimal Wasserstein order is architecture-dependent: second-order objectives dominate on the convolutional backbone, third-order objectives on the transformer backbone, and our framework surpasses comparable baselines on most metrics, with a single deterministic forward pass.

语义分割网络在固定类别集上运行,因此在部署过程中出现分布外(OOD)对象时会失败,这对于诸如自动驾驶等安全关键应用来说是一个重要的限制。可靠地识别OOD对象需要良好校准的认知不确定性,然而常见的基于softmax的置信度评分往往过于自信,而贝叶斯替代方法如蒙特卡洛丢弃(Monte Carlo dropout)或深度集成(deep ensembles)则需要昂贵的重复前向传播。证据深度学习(Evidential Deep Learning, EDL)通过将类别概率建模为从单次确定性前向传播中学习的Dirichlet分布,提供了一种高效的替代方案。现有的EDL公式依赖于欧几里得目标,这会将预测推向简单形状的顶点,鼓励过度自信,而不是为不熟悉的输入保留不确定性。相反,我们采用基于Wasserstein的目标,这尊重概率简单形状的几何特性,并在统一的证据框架内研究Wasserstein阶数对分割精度和OOD检测的影响。我们在SegmentMeIfYouCan基准上评估该框架,包括LostAndFound、RoadObstacle21、RoadAnomaly21和Fishyscapes,使用了卷积(DeepLabV3+)和基于变换器(SegFormer)的架构。我们的结果表明,最佳的Wasserstein阶数依赖于架构:在卷积骨干网络上,二阶目标占主导地位,而在变换器骨干网络上,三阶目标更为有效,并且我们的框架在大多数指标上超越了可比基线,且仅需一次确定性前向传播。

HarnessIR: Harnessing Multimodal Foundation Models for Universal Real-World Image Restoration

HarnessIR:利用多模态基础模型进行通用真实世界图像修复
Kong, Xiangtao, Liu, Shuaizheng, Wu, Rongyuan, Sun, Lingchen, Zhang, Zhengqiang, Zhao, Jinxin, Wu, Yuhui, Zhang, Lei
Abstract
Real-world low-quality images suffer from complex mixed degradations, including but not limited to noise, blur, atmospheric effects, etc. Recent agentic methods usually model real-world image restoration (Real-IR) as a sequential tool calling problem over task-specific single-degradation restoration models. This paradigm, however, is fundamentally limited because complex real-world degradations cannot be cleanly undone degradation by degradation, and the tool used for task-specific models caps the capability of the agent system. In this work, we present HarnessIR, an agentic framework for Real-IR by harnessing a multimodal foundation model (MFM) as the executor. HarnessIR consists of five stages: perception and diagnosis, on-demand tool invocation, prompt composition, execution, and verification-driven refinement. Unlike prior agentic Real-IR methods that rely on tool chains assembled from task-specific models, HarnessIR feeds the restoration requirements, the perceptual diagnosis, and the evidence into an MFM that performs restoration in a single pass, followed by verification stages to determine whether the result warrants further processing. Under our harness, off-the-shelf MFMs handle restoration tasks remarkably well, achieving state-of-the-art results on the widely used MiO100 synthetic benchmark. More importantly, by exploiting the strong generalization ability of MFMs, HarnessIR delivers compelling restoration quality on challenging real-world scenes where previous agentic IR systems often struggle.

Abstract
Recent advances in Vision-Language Models (VLMs) have led to rapid progress in video understanding across a wide range of benchmark tasks. However, existing evaluations largely focus on short-term reasoning, failing to assess a critical capability: maintaining cumulative temporal consistency over extended time horizons. To close this evaluation gap, we introduce HeiCo-FOCUS, a clinically grounded dataset for evaluating long-context video understanding through the task of Foreign Object Contextual Understanding in Surgery. Built on a dataset of Heidelberg Colorectal surgeries, this task requires models to continuously track multiple objects as they are inserted, manipulated, occluded, and removed over procedures lasting up to hours. HeiCo-FOCUS comprises 30,000 visual question answering (VQA) pairs covering five core capabilities: object recognition, temporal grounding, aggregation, event and procedural understanding, and complex reasoning. The dataset was constructed through a rigorous multi-stage annotation pipeline involving large-scale crowd annotation and 39 surgical domain experts to ensure high quality and clinical relevance. To systematically probe model behavior, we introduce a multi-track evaluation framework that progressively increases temporal and contextual demands from single frames to full procedures. Experiments with ten frontier VLMs show that HeiCo-FOCUS tasks are far from solved: only around half of the models clearly outperform a text-only baseline. Across the video tracks, models perform best on event and procedural understanding (mean Accuracy: 56.5% across all models), while temporal grounding remains particularly challenging for all evaluated models (mean Accuracy: 19.7%). We therefore expect HeiCo-FOCUS to serve as a catalyst for the development of models capable of reliable, temporally consistent reasoning over hours-long videos.

Abstract
Mishandled checked baggage remains a recurrent issue in airport operations, and current recovery workflows still largely rely on tag-based tracking, which does not directly support visual identification when tag evidence is missing or unavailable. This paper investigates baggage re-identification as an instance-level retrieval problem in a multi-camera setting, leveraging DINOv3 foundation-model representations to match a query image against a gallery of registered baggage images. A Torchreid-style BNNeck re-identification head is placed on top of a DINOv3 backbone, and parameter-efficient adaptation is performed via LoRA. Experiments are conducted on the MVB benchmark using a progressive study that compares a fully frozen backbone against LoRA and fine-tuning strategies. Results indicate that parameter-efficient adaptation of foundation-model features provides an effective and stable approach for multi-view baggage re-identification under limited training data.

Abstract
Linking people's appearance and actions to character identities is essential for understanding video narratives. We present a framework for identity-aware video captioning and person-centric question answering that combines automatic character identification, explicit spatial grounding, and task-specific adaptation. Starting from LSMDC v2 movie clips, our pipeline matches detected faces to actor reference images, tracks characters across frames, and builds inputs with identity-linked bounding boxes. A strong vision-language model generates identity-aware captions and questions, which are manually verified and filtered to create a benchmark of 750 captioned clips and 3,000 person-centric questions. We study five grounding strategies combining textual coordinates with visual face or estimated person boxes across Video-MLLM families at roughly 2B, 4B, and 8B parameters and larger frontier models. Combining visual face boxes with textual coordinates yields the most consistent performance across scales and significantly improves overall performance over coordinates alone. Smaller models tend to over-assign known identities when the queried person is not grounded, while larger models better recognize such UNIDENTIFIED cases. We introduce BAC by LoRA fine-tuning Qwen models at 2B, 4B, and 8B scales on about 32K identity-aware captioned clips. Across all scales, BAC outperforms every other evaluated model family of comparable size. BAC-8B reaches 93.20\% overall QA accuracy, ranking behind only GPT-5.6 Sol among the frontier models evaluated in our study. Overall, explicitly communicating who is where, together with lightweight task-specific adaptation, substantially improves identity-aware video understanding without changing the underlying architecture. We release the benchmark, training data, code, and BAC checkpoints at https://github.com/momentslab/beyond-anonymous-captions.

Argos: Adapt Rich Geometric Priors for Generalizable Online Scene-Change-Detection

Argos:适应丰富几何先验以实现可泛化的在线场景变化检测
Xu, Ruihan, Yoon, Jiae, Zhou, Kaichen, Kim, Ue-Hwan, Carlone, Luca
Abstract
Robots operating in dynamic environments require reliable detection of how their surroundings change over time. Existing learning-based methods largely rely on pairwise 2D image features, which struggle under large viewpoint changes and occlusions, are sensitive to noise, and show limited generalization across domains, while explicit 3D approaches typically require costly offline optimization. We show that the implicit 3D knowledge of Geometric Foundation Models (GFMs) provides a strong basis for addressing these limitations. We introduce Argos, which adapts GFM features for joint scene change detection and 3D reconstruction. To address data scarcity and take a step toward a foundation model for scene change detection, we introduce a large-scale benchmark comprising two synthetic datasets and one real-world dataset, and train jointly across diverse datasets to improve cross-domain generalization. We further introduce Argos-SLAM, a real-time system designed for robotics, which performs online change detection and change-aware 4D mapping. Across benchmarks, our framework substantially outperforms existing baselines, with gains of up to 42.01% in change IoU and 27.91% in F1, while supporting scalable deployment in changing real-world environments.

VideoEvolve: Co-Evolving Memory and Retrieval for Long Video Understanding

VideoEvolve:共同进化记忆与检索以实现长视频理解
Xu, Yongchao, Ye, Bowen, Gan, Jiefeng, Ma, Junkai, Li, Wenzhao, Tao, Sen, Wei, Yi, Liu, Jiawei
Abstract
Long video understanding increasingly relies on external memory to organize massive visual streams into compact representations. However, most memory-based methods dynamically adapt how information is retrieved for different questions, while largely fixing what is remembered. This mismatch makes missing details costly to recover, whereas stored information is valuable only when it can be reliably retrieved. To address this issue, we propose VideoEvolve, a novel self-evolving framework that jointly evolves memory and retrieval for long video understanding. Specifically, starting from a coarse low-frame-rate overview, VideoEvolve couples a Memory Evolver for selective memory augmentation with a Retrieval Evolver for adaptive retrieval over the evolving memory. We then co-evolve the two Evolvers through alternating agentic reinforcement learning (Agentic RL), updating one while freezing the other. To steer this alternating evolution, Bottleneck-Aware Evolution Feedback (BEF) identifies whether the current bottleneck lies in memory or retrieval and directs optimization toward the more limiting side. Furthermore, VideoEvolve introduces Capability-Aware Evolution Feedback (CEF) to alleviate downstream feedback from over-specializing memory to a fixed set of training questions, shifting training toward underdeveloped yet learnable video capabilities. By integrating Agentic RL with BEF and CEF, VideoEvolve transforms downstream reasoning experience into transferable capability updates, providing a concrete path from static long-video systems toward experience-driven, self-improving multimodal intelligence.

长视频理解越来越依赖外部记忆将大量视觉流组织成紧凑的表示。然而,大多数基于记忆的方法动态调整信息检索的方式以应对不同的问题,同时在很大程度上固定了记忆内容。这种不匹配使得缺失的细节恢复成本高昂,而存储的信息只有在能够可靠检索时才有价值。为了解决这一问题,我们提出了VideoEvolve,一个新颖的自我进化框架,联合进化记忆和检索以实现长视频理解。具体而言,VideoEvolve从粗略的低帧率概览开始,结合了用于选择性记忆增强的Memory Evolver与用于在不断进化的记忆上进行自适应检索的Retrieval Evolver。然后,我们通过交替的自主强化学习(Agentic RL)共同进化这两个Evolver,在更新一个的同时冻结另一个。为了引导这种交替进化,瓶颈感知进化反馈(Bottleneck-Aware Evolution Feedback, BEF)识别当前瓶颈是出现在记忆还是检索,并将优化方向指向更具限制性的一方。此外,VideoEvolve引入了能力感知进化反馈(Capability-Aware Evolution Feedback, CEF),以缓解下游反馈导致记忆过度专注于固定训练问题集的情况,推动训练向尚未开发但可学习的视频能力转移。通过将Agentic RL与BEF和CEF相结合,VideoEvolve将下游推理经验转化为可转移的能力更新,为从静态长视频系统向经验驱动的自我改进多模态智能提供了具体路径。在多个长视频理解基准上的广泛实验表明了VideoEvolve的有效性。

HuLiGen: Human LiDAR Generation from Parametric Body Models

HuLiGen:基于参数化人体模型的人体LiDAR生成
Galaaoui, Salma, Samet, Nermin, Picard, David
Abstract
LiDAR point clouds of humans are extremely expensive to collect and annotate, thus represent a scarce resource that hinders the development of human analysis using this modality. To alleviate this scarcity, prior work relies on simulated human LiDAR, but such samples do not fully reflect the geometry and sensing characteristics of real observations. In contrast, we introduce HuLiGen, a generative model that generates human LiDAR point clouds from a parametric body model, using a point transformer trained with a flow-matching objective. We show that our generated point clouds are closer to the real capture distribution. Using HuLiGen to generate synthetic data, we propose a synthetic-only pretraining scheme for LiDAR-based HPE that achieves state-of-the-art performance, with even larger gains in low-annotation and low-data regimes, where MPJPE is reduced by up to 50%.

VolCo: Volumetric Contact for High-Fidelity Human Grasp Generation

VolCo:用于高保真度人类抓取生成的体积接触
Chen, Zhuo, Cheng, Yihua, Leonardis, Aleš, Chang, Hyung Jin
Abstract
Accurate contact modeling is fundamental to understanding hand-object interaction, yet existing contact representations are typically restricted to object surfaces and rely on hand-crafted rules to recover contact details, leading to severe penetrations and implausible results. To better exploit the rich detail in motion-capture data, we introduce Volumetric Contact (VolCo), a representation that expands surface points to a set of 3D volumetric grids. VolCo encodes 3D contact that allows precise hand part recovery, and is organized in an inherent hierarchy: local contact details within each volume and global hand geometry across all volumes. Our framework, VolCoDiff, employs two modules to capture local and global features following this hierarchy. For local contact details, we use a 3D variational autoencoder to model the possible hand configurations conditioned on the local object signed distance field (SDF). For global hand geometry, we design a prior-guided diffusion model that learns the distribution of compressed latent features aggregated from the volumetric grids. We evaluate our method on two benchmark datasets and demonstrate state-of-the-art performance in penetration and stability, indicating the capability to generate tight grasps with much less severe penetrations. Our code is available at https://github.com/chzh9311/volco.

Masked Feature Encoding for Large-Scale Whole Slide Image Representation

大规模全幻灯片图像表示的掩码特征编码
He, Haoyu, Tessier-Cloutier, Basile, Wang, Yang, Hosseini, Mahdi S.
Abstract
Whole slide image (WSI) analysis in computational pathology follows a multiple instance learning (MIL) pipeline where patch embeddings are extracted independently and aggregated for slide-level prediction, but within-slide variance from staining, scanner, and local texture can overwhelm the discriminative signal. We propose Masked Feature Encoding for Multiple Instance Learning (MFE-MIL), a feature-space masking framework that trains a lightweight MLP adapter jointly with a window-based masked reconstruction branch and a MIL classification head. The two objectives are complementary. Classification guides the adapter to suppress within-slide patch variance, while window-based masked reconstruction provides an auxiliary regularizer for the adapted features without using patch coordinates, coordinate graphs, or segmentation preprocessing. The raster patch-extraction order is used only as a weak implicit prior. At inference, the decoder is removed, leaving only the adapter and MIL head. Across CAMELYON16/17, PANDA, and TCGA-BRCA with four diverse encoders, MFE-MIL improves ACC/F1 for nearly all tested aggregator-encoder settings and AUC in most, outperforms coordinate-based spatial methods (CAMIL), and achieves higher AUC than 2DMamba on three of four datasets (UNI). On five TCGA survival cohorts it improves the average concordance index for every aggregator tested, its most consistent gain. Code is available at https://github.com/AtlasAnalyticsLab/MFE-MIL.

Geometry-Supervised Visual Representation Learning for Multi-Phenotype Lesion Interpretation in Medical VLMs

几何监督的视觉表征学习用于医学视觉语言模型中的多表型病变解读
Wang, Hao, Zeng, Qiwei, Ye, Shuchang, Lin, Jinghao, Yang, Yuezhe, Peng, Yige, Kim, Jinman, Bi, Lei
Abstract
Medical vision-language models (VLMs) have shown increasing potential for clinical image interpretation. However, these models still struggle to interpret multi-phenotype lesions whose diagnosis requires the joint assessment of multiple pathological phenotypes. Existing vision-language alignment methods produce visual representations that fail to preserve anatomical hierarchies and relationships among phenotypic subclasses. This stems from their reliance on semantic supervision, which lacks geometric constraints to preserve these relationships in the visual embedding space. Moreover, the sparsity of lesion-related anatomical and phenotypic representations makes it difficult for medical VLMs to capture important diagnostic evidence. To address these limitations, we propose \textbf{PureVision}, a geometry-supervised visual representation learning framework for multi-phenotype lesion interpretation in medical VLMs. It combines a geometry-supervised representation learning module, \textbf{PureEyes}, and an anatomy-guided evidence aggregation module, \textbf{PureNeurons}. PureEyes provides geometric supervision through ideal spatial distributions that encode anatomical hierarchies and phenotypic subclass relationships. PureNeurons projects visual representations into the learned latent space, using their positions to selectively aggregate lesion-specific anatomical and phenotypic evidence. Experiments on \textit{LIDC-IDRI}, \textit{CBIS-DDSM}, and \textit{3DReasonKnee} demonstrate that PureVision improves lesion grounding and phenotype characterization in visual question answering and radiology report generation.

LoomSC: Scalable Deep Subspace Clustering with Projector Factorization and Exact Spectral Reduction

LoomSC:具有投影因子分解和精确谱降维的可扩展深度子空间聚类
Mrabah, Nairouz, Melki, Youssef, Bouguessa, Mohamed, Ksantini, Riadh, Murtaza, Shakeeb, Zia, Tehseen
Abstract
Dense self-expression matrices and full-affinity spectral clustering limit the scalability of subspace clustering. We introduce the Latent Orthogonal Optimization Model for Subspace Clustering (LoomSC), a framework that addresses both bottlenecks through projector factorization and exact spectral reduction. Motivated by the spectral structure of least-squares regression, LoomSC jointly learns latent features and a projector self-representation through two thin factors. Alternating Procrustes and least-squares updates preserve the sample factor's orthogonality while keeping the coefficient matrix implicit. We construct a nonnegative quadratic affinity that preserves the projector's support. An exact feature map then reduces its normalized spectral problem to an eigenproblem whose dimension depends only on the factor width. Neither the full affinity nor the sample Laplacian needs to be formed. Our analysis quantifies the projector approximation and identifies conditions for subspace preservation and within-subspace connectivity. For fixed dimensions and iteration budgets, the complete pipeline has linear time and memory complexity in the number of samples. Across five image-clustering benchmarks, LoomSC ranks first or second in all 15 dataset-metric comparisons against 9 state-of-the-art baselines. Its mean accuracy exceeds the highest baseline mean by 6.66 percentage points. Synthetic experiments scale to 500,000 samples while maintaining at least 99.8% accuracy.

Abstract
World action models (WAMs) have emerged as an important class of generalist robot policies, aiming to transfer video prediction priors to action learning. However, we find that existing WAMs frequently produce incorrect motion predictions in open-ended environment, leading to erroneous actions. We attribute this limitation to two factors: (1) base video models are not optimized for manipulation, and (2) naively incorporating action components into video models can substantially degrade their generalization capabilities. We introduce Video Prediction Policy 2 (VPP2), a WAM that enables strong zero-shot generalization in both video prediction and action generation. First, we curate a large-scale, diverse dataset of manipulation videos to continue pretraining the base video foundation model. We annotate video clips with detailed captions and perform \textit{event-level} video pretraining to promote generalization across open-ended manipulation tasks. Second, we post-train and distill the video model into a single-step visual planner with fixed prediction horizon. Finally, we introduce action module via a mixture-of-transformers (MoT) architecture to learn implicit inverse dynamics model. Experiments demonstrate three key results: (1) VPP2-14B outperforms Cosmos3-64B by 11.0\% points in video prediction instruction-following success rate on open-ended tasks; (2) VPP2 surpasses the strongest baseline by 18.5\% points in success rate on real-world zero-shot ALOHA manipulation tasks; and (3) following benchmark-specific post-training, VPP2 achieves the highest success rates among evaluated methods on the challenging LIBERO-Pro, LIBERO-OOD, and RoboDojo benchmarks.

$\Delta$Representation: Geometry Supervised Representation Learning of Phenotypes via Counterfactual Reasoning for Medical VLMs

Abstract
Medical vision-language models (VLMs) have shown increasing potential for radiological image interpretation. Medical VLMs encode radiological images into visual representations that capture both anatomical and phenotypic information for diagnosis. Existing approaches improve pathological phenotype representations through semantic-guided representation alignment. However, pathological phenotypes arise as lesion-specific visual changes superimposed on underlying normal anatomy. Such semantic alignment approaches fail to model the phenotype-specific increment relative to the corresponding normal anatomical representation. To address this gap, we propose \textbf{$\Delta$Representation}, a visual phenotype representation learning framework based on counterfactual reasoning for medical VLMs. It comprises \textbf{BaseAnatomy}, a geometry-supervised representation learning module, and \textbf{$\Delta$Phenotype}, a counterfactual incremental representation learning module. BaseAnatomy provides fine-grained geometric supervision through spatial relationships across and within anatomical structures. $\Delta$Phenotype computes the representation increment between lesion representations and their corresponding normal anatomical representations, and supervises increments associated with the same phenotype to cluster in the representation space. Experiments on \textit{ReXGroundingCT} and \textit{LIDC-IDRI} demonstrate that $\Delta$Representation effectively structures pathological phenotype representations and improves lesion grounding and phenotype characterization accuracy in medical VLMs. Code is available at https://anonymous.4open.science/r/deltarep-CF6D.

Abstract
Large-scale egocentric human interaction data is becoming an important source of physical supervision for embodied learning, yet video alone leaves the contact and pressure that characterize physical interaction unrecorded. Recent visual-tactile datasets provide this missing supervision, but their synchronized tactile data remain far smaller in volume than human video. Moreover, the largest resources often merge recordings from different sensors or annotation procedures, which makes the effect of data scale difficult to isolate. We therefore introduce TouchScale, a 500-hour dataset of contact-rich human interaction recorded with a single unified wearable setup. Its approximately 2K predefined task descriptions span everyday activities and structured manipulation, and each recording temporally aligns egocentric RGB-D video with wrist RGB video and dense full-hand bimanual tactile measurements. Compared with prior tactile data, training on the full TouchScale raises zero-shot contact IoU on data from an unseen tactile sensor from 0.134 to 0.383. Pretraining a visual encoder on TouchScale also yields the highest action recognition accuracy on three benchmarks among the compared visual-tactile datasets. Used for visual-tactile mid-training of a robot policy, TouchScale improves the average real-world success rate across four contact-rich manipulation tasks from 22.5% to 57.5%. With the sensor and collection protocol held fixed, both zero-shot tactile prediction and robot success show an overall upward trend as more TouchScale data is used. These results suggest that human visual-tactile data collected at scale with consistent sensing benefits both perception and robot manipulation. We will publicly release TouchScale, including all synchronized visual-tactile recordings and reconstructed object models, to support future research on scalable visual-tactile learning.

On the Necessity of Attention-FFN Split in Vision Transformers

视觉变换器中注意力-前馈网络分离的必要性
Kim, Junhyeok, Kim, Jinyeong, Park, Jae Wan, Hwang, Seong Jae
Abstract
The standard Transformer architecture relies on a rigid pattern that alternates Attention and Feed-Forward Network (FFN) layers. Despite its widespread adoption, the inductive bias imposed by this strict separation has not been systematically examined. In this work, we investigate the necessity of the Attention-FFN dichotomy in Vision Transformers (ViTs). To facilitate this analysis, we introduce the AttenFeed module, a unified component that integrates the functional properties of both Attention and FFN. Based on this module, we devise the unified Vision Transformer (uViT), which replaces the conventional alternating Attention-FFN structure with a sequence of AttenFeed modules. We then use uViT as a control group that relaxes the Attention-FFN dichotomy of the standard ViT and systematically compare the two models across multiple datasets and model scales. Our experiments reveal that the Attention-FFN dichotomy can hinder performance at smaller model scales due to the rigid parameter allocation of ViTs. The AttenFeed module and uViT serve as new analytical tools for understanding the Attention-FFN structure and offer theoretical insights into the heuristically designed architecture of conventional ViTs.

Abstract
Scientific image segmentation methods rely on extensive annotation and task-specific training, limiting adaptation across imaging modalities and experimental conditions. We present a training-free, one-shot framework that specializes vision foundation models using a single annotated reference image. The framework combines DINOv3 representations with background-adaptive feature orthogonalization to suppress artifact-related feature directions, after which cosine similarity localizes candidate regions for SAM segmentation. We evaluate the framework on red-blood-cell microscopy, structured-illumination pool boiling, and chest radiography. Relative to the strongest baseline, the proposed method improves mean IoU by 5.91% and 78.62% on the microscopy and pool-boiling datasets, respectively, while achieving comparable performance on chest radiographs. These results demonstrate that one-shot reference conditioning can adapt general-purpose vision models to specialized scientific segmentation tasks.

From Digital Human Interactions to Physics-Based Humanoid Skills: Physics-Grounded Post-Training of Interaction Generators

从数字人类交互到基于物理的人形技能:基于物理的交互生成器后训练
Chen, Kerui, Zhang, Jianrong, Lv, Kai, Fan, Hehe
Abstract
Recent methods have made promising progress in generating interactions between two humanoids, largely relying on physics-based tracking policies to convert digital reference motions into executable trajectories. However, limited tracking capabilities restrict the range of reference motions that can be successfully executed, reducing data utilization. Moreover, even successful tracking does not guarantee physically plausible responses or faithful realization of the intended interactions. In this paper, we introduce DIGHT, a co-adaptive framework that couples a Digital human Interaction Generator with a Humanoid Tracking policy. Our DIGHT first executes multiple text-conditioned interaction candidates in simulation using a fixed tracker. It then constructs physics-grounded preferences from the resulting rollouts, covering both general executability and interaction fidelity. Rather than collapsing these signals into a single scalar reward for candidate ranking, we align the pretrained generator using physics-decoupled diffusion direct preference optimization (DPO), preserving criterion-specific supervision without differentiating through the simulator. To improve executability, preference pairs are derived from tracking error, friction, and floating. Additionally, to improve interaction fidelity, we propose to incorporate force feedback from simulator as a measure of contact fidelity and construct preferences over contact occurrence, location, duration, and force magnitude. The aligned generator then supplies reference motions for fine-tuning the tracker, improving compatibility between generation and physical execution. Extensive experiments demonstrate that our approach not only improves the physical plausibility of generated motions but also enables more reliable and faithful humanoid interactions in simulation.

最近的方法在生成两个类人之间的交互方面取得了可喜的进展,主要依赖基于物理的跟踪策略将数字参考动作转换为可执行轨迹。然而,有限的跟踪能力限制了能够成功执行的参考动作范围,从而降低了数据的利用率。此外,即使成功跟踪,也并不能保证物理上合理的响应或忠实实现预期的交互。在本文中,我们介绍了DIGHT,一个将数字人类交互生成器与人形跟踪策略相结合的共适应框架。我们的DIGHT首先使用固定跟踪器在模拟中执行多个文本条件的交互候选。然后,它从生成的回放中构建基于物理的偏好,涵盖一般可执行性和交互保真度。我们并不将这些信号合并为单一标量奖励进行候选排名,而是通过物理解耦扩散直接偏好优化(DPO)对预训练生成器进行对齐,保留特定标准的监督而不通过模拟器进行微分。为了提高可执行性,偏好对是从跟踪误差、摩擦和漂浮中得出的。此外,为了提高交互保真度,我们建议将来自模拟器的力反馈作为接触保真度的衡量标准,并构建关于接触发生、位置、持续时间和力大小的偏好。对齐后的生成器随后为微调跟踪器提供参考动作,提高生成与物理执行之间的兼容性。大量实验表明,我们的方法不仅提高了生成动作的物理合理性,还在模拟中实现了更可靠和真实的人形交互。

Performance at What Cost? A Sustainability-Aware Performance Index for Cell and Nucleus Instance Segmentation

性能的代价是什么?一种关注可持续性的细胞和细胞核实例分割性能指数
Sheikh, Eiram Mahera, Tharwat, Alaa, Schenck, Wolfram
Abstract
Pretrained models for cell and nuclear instance segmentation differ substantially in architecture, pretraining data and objectives, parameter count, inference strategy, adaptation requirements, postprocessing pipeline, and computational demand. Large pretrained and foundation models are increasingly adopted because of their strong zero-shot capabilities, but their use also imposes greater energy consumption, memory requirements, computational demands, adaptation costs, and operational carbon emissions. Whether these additional demands are justified by meaningful gains in segmentation performance remains unclear. We address this question by introducing the Sustainability-Aware Performance Index (SAPI), a configurable metric that combines segmentation performance, energy consumption, and model size. We benchmark 19 pretrained and foundation models across six CellBinDB datasets under zero-shot inference and evaluate 16 fine-tunable models using few-shot adaptation with both frozen encoder and full-model fine-tuning. We estimate energy consumption for GPU, CPU, and RAM using software-based monitoring tools. Our results show that larger and more computationally demanding models do not consistently achieve proportionate improvements in segmentation quality. While few-shot adaptation benefits several models, the gains and resource costs vary considerably across architectures, datasets, and adaptation strategies, causing SAPI-based rankings to differ from rankings based on performance alone. This study provides a practical framework for comparing segmentation models more comprehensively and supports more computationally accessible and environmentally responsible model selection in biomedical image analysis.

用于细胞和细胞核实例分割的预训练模型在架构、预训练数据和目标、参数数量、推理策略、适应需求、后处理流程以及计算需求等方面存在显著差异。由于其强大的零-shot 能力,大型预训练和基础模型越来越受到青睐,但它们的使用也带来了更高的能耗、内存需求、计算负担、适应成本和运营碳排放。这些额外的需求是否通过显著的分割性能提升得到了合理的 justification 仍不清楚。我们通过引入可持续性意识性能指数(Sustainability-Aware Performance Index, SAPI)来解决这个问题,这是一种可配置的指标,结合了分割性能、能耗和模型大小。我们在六个 CellBinDB 数据集上对 19 个预训练和基础模型进行了基准测试,采用零-shot 推理,并使用冻结编码器和全模型微调的少量样本适应评估了 16 个可微调模型。我们使用基于软件的监控工具估算 GPU、CPU 和 RAM 的能耗。我们的结果表明,较大且计算需求更高的模型并不总是能在分割质量上实现成比例的提升。虽然少量样本适应对多个模型有益,但不同架构、数据集和适应策略之间的收益和资源成本差异显著,导致基于 SAPI 的排名与仅基于性能的排名有所不同。本研究提供了一个实用框架,以更全面地比较分割模型,并支持在生物医学图像分析中进行更具计算可达性和环境责任感的模型选择。

How Private is Private? A Comparative Study for Face De-Identification

隐私到底有多隐私?面部去标识化的比较研究
Wei, Hui, Yu, Hao, Kuurila-Zhang, Hui, Zhao, Guoying
Abstract
Face de-identification (FDeID) has emerged as a critical privacy-preserving technology, yet its evaluation remains fundamentally fragmented. Existing protocols rely on inconsistent metrics, heterogeneous datasets, and partial annotation coverage, so methods targeting different utility dimensions, such as landmark versus expression preservation, are reported on different benchmarks under different metrics, rendering cross-method comparison infeasible. We revisit FDeID evaluation from both the data and metric perspectives. On the data side, we introduce UtilFace, a curated, demographically balanced benchmark with high identity diversity, assembled from four large-scale face datasets through identity-aware cleaning, resolution enhancement, and stratified filtering. On the metric side, we propose HiFD, a Hierarchical Face De-identification metric that unifies identity suppression, multi-level utility preservation, and image quality under a single consistency-based paradigm: every component is computed from pretrained estimators' outputs on the original face and its de-identified counterpart, directly quantifying how much identity is suppressed and how much downstream-perceivable utility survives. HiFD organizes facial signals into a three-level utility hierarchy spanning macro cues (L1), micro cues (L2), and imperceptible cues (L3), and aggregates the five resulting components into a single interpretable score via weighted harmonic mean, with configurable application-specific profiles. Using this unified protocol, we conduct a comprehensive comparative study spanning adversarial, GAN-based, and diffusion-based methods, surfacing trade-offs and failure modes that remain invisible under existing protocols. We release the benchmark and evaluation toolkit to foster systematic and reproducible research in privacy-preserving human face analysis.

面部去标识化(FDeID)作为一种关键的隐私保护技术,已逐渐受到重视,但其评估仍然存在根本性的碎片化问题。现有协议依赖于不一致的指标、异质的数据集和部分注释覆盖,因此针对不同效用维度(如地标与表情保留)的不同方法在不同的基准下以不同的指标进行报告,使得跨方法比较变得不可行。我们从数据和指标两个角度重新审视FDeID评估。在数据方面,我们引入了UtilFace,这是一个经过策划的、在人口统计上平衡的基准,具有高身份多样性,来源于四个大规模面部数据集,通过身份感知清理、分辨率增强和分层过滤而构建。在指标方面,我们提出了HiFD,这是一种层次化面部去标识化指标,将身份抑制、多级效用保留和图像质量统一在一个基于一致性的范式下:每个组件都是从预训练估计器在原始面部及其去标识化对应物上的输出计算得出的,直接量化身份被抑制的程度和下游可感知效用的保留程度。HiFD将面部信号组织成一个涵盖宏观线索(L1)、微观线索(L2)和不可感知线索(L3)的三层效用层级,并通过加权调和平均将五个结果组件汇总为一个可解释的分数,具有可配置的应用特定配置文件。利用这一统一协议,我们开展了一项全面的比较研究,涵盖对抗性、基于GAN和基于扩散的方法,揭示了在现有协议下仍然不可见的权衡和失败模式。我们发布了该基准和评估工具包,以促进隐私保护人脸分析领域的系统性和可重复性研究。

When to Unpair: Regulating Pairing Dependence in Medical Visual In-Context Learning

何时解除配对:调节医学视觉上下文学习中的配对依赖性
Wan, Cheng, Li, Chenjun, Zhao, Qingyu
Abstract
Visual in-context learning (ICL), well suited to label-scarce medical imaging, uses support image-label pairs to demonstrate input-output mappings, while the labels collectively indicate the requested task. We diagnose dependence on individual pairings with a test-time derangement that reassigns every support label to another support image while preserving the query, support images, and label multiset. The resulting pairing gap, defined as shuffled-minus-matched performance, shows that all four released models depend on the pairing, to widely varying degrees. Further analysis of a paired-trained model reveals support-associated spurious regions and lesion-size biases even with real, unaltered supports, alongside sensitivity to mis-registered support labels. To regulate this dependence, we introduce a late unpairing curriculum (LUC), which starts with matched training and then applies random unpairing, replacing each support label with that of another support in the same episode. LUC nearly closes the pairing gap on two backbones while maintaining or improving matched-support performance across all evaluated task types, with gains extending to held-out tasks and cross-dataset episodes. It also mitigates these failure modes. On BraTS whole-tumor segmentation, matched-support DSC rises from 0.733 to 0.857 while the gap shrinks from -0.184 to -0.008. In a released model, brief fine-tuning with random unpairing reduces the gap. A reversed curriculum that places the same number of unpairing epochs at the start of training leaves a large gap. This shows that pairing dependence is shaped by the order of training and not only by the amount of unpaired training.

视觉上下文学习(ICL)非常适合标签稀缺的医学影像,它利用支持图像-标签对来展示输入-输出映射,同时标签共同指示请求的任务。我们通过一种测试时的扰动方法诊断对单个配对的依赖性,该方法在保持查询、支持图像和标签多重集的同时,将每个支持标签重新分配给另一个支持图像。由此产生的配对差距定义为打乱后减去匹配的性能,显示出所有四个发布的模型在不同程度上依赖于配对。对一个经过配对训练的模型的进一步分析揭示了与支持相关的虚假区域和病灶大小偏差,即使在真实且未修改的支持下,也存在对错误注册的支持标签的敏感性。为了调节这种依赖性,我们引入了一种后期解除配对的课程(LUC),该课程从匹配训练开始,然后应用随机解除配对,将每个支持标签替换为同一回合中另一个支持的标签。LUC几乎消除了两个基础模型上的配对差距,同时在所有评估的任务类型中保持或提高了匹配支持的性能,收益扩展到保留任务和跨数据集回合。在BraTS全肿瘤分割中,匹配支持的DSC从0.733上升到0.857,而差距从-0.184缩小到-0.008。在一个发布的模型中,短暂的随机解除配对微调减少了差距。一个将相同数量的解除配对周期放在训练开始的反向课程留下了较大的差距。这表明配对依赖性是由训练顺序塑造的,而不仅仅是由无配对训练的数量决定的。

Position Forcing: Self-Conditioning 3D Generation

位置强制:自条件化的三维生成
Ouyang, Ziheng, Lai, Zeqiang, Chen, Jiarui, Wang, Jiangshan, Wan, Yuhao, Gong, Jingbo, Yue, Xiangyu, Zhao, Hengshuang, Hou, Qibin, Guo, Chunchao
Abstract
Recent single-stage 3D generative models commonly adopt VecSet representations, encoding 3D shapes as unordered sets of latent tokens. However, compared with two-stage methods that provide explicit positional guidance, these models must implicitly infer token positions throughout denoising, limiting their generation quality. We observe that, despite the absence of explicit positional conditioning, VecSet tokens retain recoverable spatial correspondences. Building on this observation, we propose Position Forcing, a position-based self-conditioning framework. During denoising, Position Forcing recovers token positions from the current clean latent estimate, quantizes them at progressively finer resolutions according to the denoising stage, and feeds the resulting positional encodings back into the diffusion Transformer. This progressively refined positional feedback provides spatial guidance at a granularity appropriate to each denoising stage, guiding shape generation along a coarse-to-fine trajectory and substantially improving generation quality without a separate position generation stage. Experiments demonstrate that Position Forcing achieves strong performance among single-stage 3D generative methods and outperforms several competitive multi-stage approaches.

最近的单阶段三维生成模型通常采用 VecSet 表示法,将三维形状编码为无序的潜在标记集合。然而,与提供明确位置指导的双阶段方法相比,这些模型必须在去噪过程中隐式推断标记位置,从而限制了生成质量。我们观察到,尽管缺乏明确的位置条件,VecSet 标记仍然保留可恢复的空间对应关系。基于这一观察,我们提出了位置强制(Position Forcing),一种基于位置的自条件化框架。在去噪过程中,位置强制从当前的干净潜在估计中恢复标记位置,根据去噪阶段以逐步更精细的分辨率对其进行量化,并将生成的位置信息编码反馈到扩散 Transformer 中。这种逐步细化的位置反馈在适合每个去噪阶段的粒度上提供空间指导,沿着粗到细的轨迹引导形状生成,并显著提高生成质量,而无需单独的位置生成阶段。实验表明,位置强制在单阶段三维生成方法中表现出色,并且优于几种竞争性的多阶段方法。

Real-Time Joint Audio-Video Generation by Parallel Adapter Composition

通过并行适配器组合实现实时联合音视频生成
Li, Jingyu, Xiang, Xiaoxiao, Guo, Yiwen
Abstract
Deploying a joint audio-video diffusion transformer for real-time, interactive generation normally requires two essential modifications: block-autoregressive attention, so frames can be emitted before the whole clip is finished, and few-step sampling, so each block is cheap. Conventionally, the streaming video literature obtains both capabilities from a chained pipeline. It first distills a bidirectional teacher into a causal student, then into a few-step one, or proceeds in reverse order. Each stage of such a chain fine-tunes the weights the previous one produced, so a later objective can undo an earlier capability. Following the idea of model merging, we show that on a packed audio-video backbone the two capabilities can be acquired in parallel. A causal adapter is trained against the frozen backbone, and an off-the-shelf few-step adapter provides the few-step capability. As the two edit different functional axes, we predict, and then verify, that their weight-update directions are near-orthogonal, without any explicit orthogonality constraint during training. Orthogonal updates should combine without interfering, so parallel composition is a direct sum. The two adapters are simply added at inference, with no joint training, yielding few-step, streaming audio-video whose image quality tracks the bidirectional teacher. Compared to the chained baselines, the composed model matches or beats them on most metrics, making parallel composition a practical approach. The resulting streaming system generates joint audio-video in real time, $\approx$26 fps at $480\times832$ without quantization, and sustains 30 s of continuous generation with stable image quality.

部署一个联合音视频扩散变换器以实现实时交互生成通常需要两个基本修改:块自回归注意力,以便在整个片段完成之前可以发出帧,以及少步采样,以使每个块的计算成本较低。传统上,流媒体视频文献通过链式管道获得这两种能力。它首先将双向教师模型提炼为因果学生模型,然后再提炼为少步模型,或按相反顺序进行。该链的每个阶段都会微调前一个阶段产生的权重,因此后续目标可以撤销早期能力。遵循模型合并的思路,我们展示了在一个紧凑的音视频主干上,这两种能力可以并行获得。一个因果适配器在冻结的主干上进行训练,而一个现成的少步适配器提供少步能力。由于这两个适配器编辑不同的功能轴,我们预测并验证了它们的权重更新方向几乎正交,在训练过程中没有任何显式的正交性约束。正交更新应该可以无干扰地组合,因此并行组合是一个直接和。两个适配器在推理时简单相加,无需联合训练,生成的少步流媒体音视频图像质量与双向教师模型相当。与链式基线相比,组合模型在大多数指标上与之匹配或超越,使得并行组合成为一种实用的方法。最终生成的流媒体系统以约26帧每秒的速度在480×832的分辨率下实时生成联合音视频,并能够持续生成30秒,保持稳定的图像质量。

Explicit Geometric Chain-of-Thought for Vision-Language-Action in Autonomous Driving

自主驾驶中的视觉-语言-行动显式几何思维链
Gui, Xingtai, Zhou, Yucheng, Guo, Dongqian, Gong, Jiahao, Tan, Feiyang, Shen, Jianbing
Abstract
Vision-language-action~(VLA) models have emerged as a promising paradigm for autonomous driving. However, existing VLA models still suffer from a fundamental mismatch: driving actions require precise 3D geometric cues, while visual-language understanding and reasoning are largely conducted in a 2D semantic space. In this paper, we propose GeoCoTDrive, an explicit geometric chain-of-thought framework that grounds geometry in a planning-oriented manner. GeoCoTDrive follows a think with 2D first, drive with dedicated 3D priors paradigm. It first grounds 2D regions corresponding to decision-critical cues, and then retrieves localized 3D priors by sampling features from a geometric foundation model within the grounded regions. These localized geometric features are interleaved into the autoregressive context to support the trajectory generation. To supervise this process, we introduce planning-relevant grounding, a new region-level grounding task that focuses on local spatial cues directly affecting ego planning decisions, and construct the PlanningGrounding dataset to endow VLAs with planning-oriented grounding capability. Experiments across multiple end-to-end autonomous driving benchmarks show that GeoCoTDrive consistently improves safety-critical planning performance, demonstrating the effectiveness of the explicit geometric chain-of-thought process for VLA-based planning.

MOTIP2: Spatial Priors for End-to-End Multi-Object Tracking

MOTIP2:端到端多目标跟踪的空间先验
Roussel, Benoît, Bouet, Damien, Chen, Liming, Perrault, Pierre
Abstract
End-to-end multi-object trackers have narrowed the gap with classical tracking-by-detection on association-difficult benchmarks. Yet they still make spatially implausible errors no classical tracker would, such as assigning one identity to objects on opposite sides of the frame. A model could learn to avoid them, but tracking annotations are scarce, so we encode spatial priors explicitly instead, while keeping inference fully end-to-end with no post-hoc association. We propose three spatial priors, at the data, loss, and representation stages. Spatial ID Switches bias trajectory permutations toward spatially overlapping objects, reducing the mismatch between training and inference confusions. Spatial ID Loss scales each identity's penalty by its box distance, so a distant switch costs more than a nearby one. Spatial Anchor gives each track token its frame position, an explicit spatial cue for attention. We instantiate the three priors in MOTIP2, a tracker adapted from MOTIP and built on the real-time DEIM detection transformer. Trained without extra data, its main model, MOTIP2-L, sets a new state of the art: 73.4 HOTA on DanceTrack, 76.0 on SportsMOT, and 71.1 IDF1 on PersonPath22. MOTIP2 is a family of models spanning the speed-accuracy trade-off: a lighter model, MOTIP2-S, matches the original MOTIP at over 3x the speed, and MOTIP2-X reaches 74.8 HOTA on DanceTrack.

端到端多目标跟踪器在难以关联的基准测试中已缩小了与经典检测跟踪方法的差距。然而,它们仍然会犯一些经典跟踪器不会犯的空间上不合理的错误,例如将一个身份分配给帧两侧的物体。模型可以学习避免这些错误,但跟踪注释稀缺,因此我们显式地编码空间先验,同时保持推理完全端到端,没有事后关联。我们在数据、损失和表示阶段提出了三种空间先验。空间身份切换(Spatial ID Switches)使轨迹排列偏向空间重叠的物体,从而减少训练和推理混淆之间的不匹配。空间身份损失(Spatial ID Loss)根据每个身份的框距离来缩放惩罚,因此远处的切换成本高于近处的切换。空间锚点(Spatial Anchor)为每个跟踪令牌赋予其帧位置,提供了一个显式的空间线索以供注意。我们在MOTIP2中实例化了这三种先验,该跟踪器是从MOTIP改编而来,并基于实时DEIM检测变换器构建。MOTIP2的主模型MOTIP2-L在没有额外数据的情况下训练,创造了新的最先进水平:在DanceTrack上达到73.4 HOTA,在SportsMOT上达到76.0,在PersonPath22上达到71.1 IDF1。MOTIP2是一系列模型,涵盖了速度与准确性的权衡:更轻的模型MOTIP2-S在速度上超过原始MOTIP的3倍,而MOTIP2-X在DanceTrack上达到了74.8 HOTA。

Gaussian Density Splatting Network

高斯密度溅射网络
Shang, Miao, Wang, Yabin, Hong, Xiaopeng
Abstract
This paper proposes a novel crowd counting approach, the Gaussian Density Splatting Network (GDSNet). Unlike methods that rely on conventional, grid-based density maps and are sensitive to spatial resolution, GDSNet represents a crowd as a superposition of continuous 2D Gaussian primitives. Our approach is built upon two key contributions. First, we introduce a control-point-based fitting mechanism to structure the prediction of the Gaussian parameters. We design a method to allocate a set of control points that define local regions, from which features are pooled to regress each primitive's parameters. Second, we adapt a differentiable Gaussian Splatting framework to the counting task by parameterizing each primitive with geometric parameters and a scalar density mass. This formulation allows the network to be trained end-to-end via spatial matching of differentiably rendered density maps, naturally providing both local density supervision and global count optimization. Extensive evaluations on four standard benchmarks show GDSNet consistently outperforms the state of the art.

Self-correction Optimization for Interleaved Multimodal Generation

交错多模态生成的自我修正优化
You, Xin, Ning, Zhiwei, Chen, Zukai, Zhang, Minghui, Shi, Xuanke, Zhang, Hanxiao, Liu, Jingsong, Yang, Jie, Wang, Quan, Gu, Yun
Abstract
Multimodal large language models (MLLMs) have made significant progress in visual understanding and generation. However, generating interleaved image--text content remains challenging, as it requires tightly integrated multimodal understanding and generation capabilities. Although existing MLLMs provide promising solutions, most rely on additional training with augmented data, which is computationally expensive and remains limited in preserving visual subjects, temporal consistency, and physical plausibility. In this work, we propose self-correction optimization (SCO), an effective training-free method for consistent interleaved generation. SCO treats the classifier-free guidance update as a reference and performs minimal self-correction under two complementary constraints, including new-event and state-preserving constraints. Specifically, the new-event constraint promotes temporal consistency across image--text sequences, while the state-preserving constraint maintains the coherence of visual subjects throughout subsequent generation steps. Experiments on challenging interleaved multimodal generation benchmarks demonstrate significant improvements in temporal coherence and visual-subject preservation. Furthermore, SCO can be extended to video generation and improves the modeling of physically grounded processes, including robot manipulation and long-horizon handcrafting.

多模态大型语言模型(MLLMs)在视觉理解和生成方面取得了显著进展。然而,生成交错的图像-文本内容仍然具有挑战性,因为这需要紧密集成的多模态理解和生成能力。尽管现有的MLLMs提供了有前景的解决方案,但大多数依赖于使用增强数据进行额外训练,这在计算上是昂贵的,并且在保持视觉主题、时间一致性和物理合理性方面仍然有限。在本研究中,我们提出了一种自我修正优化(SCO),这是一种有效的无训练方法,用于一致的交错生成。SCO将无分类器引导更新视为参考,并在包括新事件约束和状态保持约束的两个互补约束下进行最小自我修正。具体而言,新事件约束促进了图像-文本序列之间的时间一致性,而状态保持约束则在后续生成步骤中保持视觉主题的一致性。在具有挑战性的交错多模态生成基准上的实验表明,时间一致性和视觉主题保持方面有显著改善。此外,SCO可以扩展到视频生成,并改善物理基础过程的建模,包括机器人操作和长时间手工制作。

Rubix: Global Correspondence-Free Point Set Alignment through Assignment Geometry

Rubix:通过赋值几何实现全局无对应点集对齐
Bhattacharjee, Subhransu S., Campbell, Dylan, Shome, Rahul
Abstract
Procrustes-Wasserstein alignment jointly estimates a matching and rotation without supplied correspondences, but alternating minimization can stop at suboptimal solutions. Rubix solves the equally weighted planar problem globally under squared Euclidean loss. Each matching $\sigma$ of two centered $n$-point sets defines a complex correlation $z_\sigma=\sum_i\bar x_i y_{\sigma(i)}$. Their convex hull is the permutation polygon: supporting vertices give optimal matchings at fixed rotations, and the farthest vertex gives the global alignment. We prove the sharp bound of $n(n-1)$ vertices for $n\ge2$, answering Rote's rotation-assignment open problem. In exact arithmetic, assignment queries recover the polygon in $\mathcal O(n^5)$ operations. Assignment-based bounds extend the approach to three-dimensional rotations and partial matching at a supplied translation through branch-and-bound. On timed MPEG-7 shape pairs, Rubix attains every numerical reference value in 12 ms on average, 50 times faster than a rotation grid at the same accuracy. Its distances improve gravity-aligned matching of real 3D scans, shape retrieval and noisy crystal classification over alternating minimization.

GraphRectify: Graph-Based Transfer of Adversarial Example Detectors Across Neural Networks

GraphRectify:基于图的对抗样本检测器在神经网络间的迁移
Vashagh, Arash, Razavi-Far, Roozbeh
Abstract
Adversarial example detectors are often tied to the classifier backbone they were trained on, limiting reuse when the protected model is replaced or upgraded. Directly transferring such detectors across backbones is challenging because different networks generally produce incompatible internal representations. We propose GraphRectify, a graph-based framework for transferring adversarial image detectors across classifier backbones. GraphRectify learns a structured representation of intermediate classifier features and adapts representations from a new backbone to the detector learned on the original model, enabling detector reuse. We evaluate GraphRectify across multiple datasets, backbone architectures, and adversarial attacks, including detector-aware adaptive attacks that jointly target the classifier and detector. Across the complete evaluation matrix, GraphRectify achieves higher aggregate ROC-AUC than training a detector from scratch on the new backbone and the evaluated transfer ablations. The gains are particularly strong for transfers between different backbone families and when sufficient data are available. In contrast, training from scratch remains competitive in the most data-limited settings. These results show that adversarial detection knowledge can transfer effectively across heterogeneous classifier architectures rather than being relearned whenever the protected backbone changes.

SGF+: Decoupling Gradient Flows for Autoregressive Video Generation

Abstract
Autoregressive video generation requires denoising the current frames while writing their key-value representations as context for future predictions. However, these two roles typically share parameters, and we find that their gradients exhibit distinct patterns and systematic negative alignment, hindering the joint optimization of visual quality and temporal consistency. We introduce Self Gradient Forcing Plus (SGF+), which assigns separate parameters to context writing and denoising while preserving their interaction through causal attention. Both roles are jointly optimized using the original generation objective without auxiliary losses, with context writing supervised through its contribution to future predictions. This simple change improves visual quality and long-horizon consistency over the evaluated baselines in both framewise and chunkwise generation, without additional video training data or a longer training horizon. Trained on only 5s rollouts, SGF+ supports continuous generation for up to 24 hours without long-video fine-tuning. These results highlight role-specific parameterization as an effective design principle for high-quality autoregressive video generation and native long-horizon extrapolation.

Detecting Adversarial Images through Response Profiles of Vision-Language Models

通过视觉-语言模型的响应特征检测对抗性图像
Vashagh, Arash, Razavi-Far, Roozbeh
Abstract
Adversarial perturbations can alter the predictions of frozen vision-language models (VLMs) while leaving their confidence and image--text similarity patterns seemingly plausible. We investigate whether we can identify adversarial inputs based on the broader way an image interacts with a collection of general semantic prompts. Our detector summarizes these responses using category-level statistics, relationships among prompts, deviations from clean reference distributions, and stability under weak image transformations, producing a compact response profile that is classified by a lightweight model while the VLM remains fixed. We evaluate the approach on multiple public image datasets, several CLIP-style visual backbones, and a range of gradient-based, optimization-based, automated, and spatial attacks. The detector achieves strong discrimination in attack-specific settings and retains substantial performance when evaluated on attacks not seen during training. Under a controlled detector-specific protocol, the response-profile representation outperforms the evaluated embedding-geometry baselines. Additional analyses show that the feature groups provide complementary information and that the method remains effective under variations in the prompt configuration. We also examine inference cost and performance against detector-aware adaptive attacks.

ECHO: Embodied Camera Observations of Human Object Carrying

ECHO:人类物体携带的具身相机观察
Sun, Xuefei, Achey, Lorin, Hamilton, Kali, Speranzon, Alberto, Grebe, Gregory, Bisk, Yonatan, Heckman, Christoffer
Abstract
Embodied and assistive agents must do more than recognize objects: they must reason about where an object belongs given the layout of an environment and the habits of the people who live in it. Progress on this problem has been limited, in part because no dedicated benchmark or dataset exists to define and evaluate it. Existing RGB-D scan datasets reconstruct static rooms without human activity, while human-object-interaction datasets capture motion without a navigable, fully reconstructed scene or a ground-truth notion of an object's natural destination. We introduce contextual object placement as a benchmark task: predicting an object's destination during an observed object-carrying episode. To support this task, we present Embodied Camera observations of Human Object carrying (ECHO), a large-scale synthetic dataset that pairs dense RGB-D scans of indoor scenes with recordings of an embodied human carrying everyday objects to context-appropriate destinations. ECHO is the first publicly available dataset to combine reconstructed scenes, human activity, natural language, and contextual-placement annotations. It comprises 3,805 human-annotated episodes across 159 floors of 115 HM3D scenes, involving 198 distinct objects. Each floor includes a complete RGB-D scan with human-annotated room labels and a surface list. Each episode provides synchronized RGB-D encounter clips; 6-DoF camera, human, and object trajectories; start and destination surfaces; an action caption; and a human-written context: a single sentence describing the inhabitant's routine that implies the destination without naming it. We evaluate contextual object placement using input-masked probes and an end-to-end baseline. Results show that no single input modality is sufficient, highlighting the need to jointly reason over scene structure, human activity, and contextual knowledge.

具身和辅助代理不仅需要识别物体,还必须根据环境的布局和居住在其中的人的习惯推理物体的归属。对此问题的研究进展有限,部分原因在于缺乏专门的基准或数据集来定义和评估该问题。现有的RGB-D扫描数据集重建了没有人类活动的静态房间,而人类-物体交互数据集则捕捉了运动,但缺乏可导航的、完全重建的场景或物体自然目的地的真实概念。我们提出了上下文物体放置作为基准任务:在观察到的物体携带事件中预测物体的目的地。为支持这一任务,我们呈现了人类物体携带的具身相机观察(ECHO),这是一个大规模合成数据集,将室内场景的密集RGB-D扫描与具身人类携带日常物品到适当目的地的记录相结合。ECHO是第一个公开可用的数据集,结合了重建场景、人类活动、自然语言和上下文放置注释。该数据集包含3,805个经过人类注释的事件,涵盖115个HM3D场景的159个楼层,涉及198种不同的物体。每个楼层包括完整的RGB-D扫描,带有人类注释的房间标签和表面列表。每个事件提供同步的RGB-D接触片段;6自由度的相机、人类和物体轨迹;起始和目的地表面;一个动作说明;以及一个人类撰写的上下文:一句描述居民日常活动的句子,暗示目的地而不直接命名。我们使用输入掩码探针和端到端基线评估上下文物体放置。结果表明,单一输入模态不足,强调了共同推理场景结构、人类活动和上下文知识的必要性。

MORCA: Offline-to-Online Reinforcement Learning for Adaptive Cache Reuse in Video Diffusion Acceleration

MORCA:用于视频扩散加速的自适应缓存重用的离线到在线强化学习
Xiong, Yuxiang, Wang, Ruiyan, Wang, Wenqiang, Hu, Teng, Shen, Songhang, Feng, Bohao, Deng, Hongqian, Yi, Ran
Abstract
Diffusion Transformers (DiTs) achieve remarkable performance in video synthesis, but their iterative denoising process suffers from high inference latency. To address this, caching has emerged as an effective acceleration strategy by capitalizing on inter-step redundancy during denoising. Existing dynamic caching methods typically estimate the error that cache reuse would introduce at each denoising step (step error) to guide cache decisions, whereas our concern is how much quality loss cache reuse would cause in the final generated video (terminal error). We show that step error does not directly correspond to terminal error and that latent information helps capture their relationship, thereby informing cache decisions. Moreover, existing threshold-based methods cannot provide precise speedup control, making it difficult to meet practical requirements for user-specified acceleration targets. To address these limitations, we introduce MORCA, a cache scheduling framework trained through offline-to-online reinforcement learning to make latent-aware reuse/recompute decisions under user-specified acceleration targets. Extensive experiments on different video generation models across multiple target acceleration ratios demonstrate that MORCA achieves better generation fidelity than state-of-the-art caching methods under comparable computational budgets. Code is available at https://github.com/x10ngyx/MORCA.

扩散变换器(Diffusion Transformers, DiTs)在视频合成中表现出色,但其迭代去噪过程面临高推理延迟的问题。为了解决这一问题,缓存作为一种有效的加速策略,通过利用去噪过程中的步骤冗余而应运而生。现有的动态缓存方法通常在每个去噪步骤中估计缓存重用所引入的误差(步骤误差),以指导缓存决策,而我们的关注点在于缓存重用对最终生成视频造成的质量损失(终端误差)。我们展示了步骤误差与终端误差并不直接对应,并且潜在信息有助于捕捉它们之间的关系,从而为缓存决策提供信息。此外,现有的基于阈值的方法无法提供精确的加速控制,使得满足用户指定的加速目标变得困难。为了解决这些限制,我们提出了MORCA,一个通过离线到在线强化学习训练的缓存调度框架,能够在用户指定的加速目标下做出潜在信息感知的重用/重新计算决策。在多个目标加速比下对不同视频生成模型的广泛实验表明,MORCA在可比计算预算下实现了比最先进的缓存方法更好的生成保真度。代码可在 https://github.com/x10ngyx/MORCA 获取。

Label-free cell counting and viability prediction with brightfield imaging and deep learning

无标记细胞计数与活性预测:基于明场成像与深度学习
Vazifeh, Amir Reza, Zeigler, Christian, Meyyappan, Sornanathan, Jeske, Richard, Fleischer, Jason W.
Abstract
Cell viability assessment is a core requirement in cell culture systems, with critical applications in biopharmaceutical manufacturing and drug development. Conventionally, it is measured by adding membrane-impermeable dyes to a sample (a process called staining), which allows compromised cell membranes to be distinguished from intact ones. However, staining has several limitations: (a) chemical agents can perturb normal cellular processes of the cells being measured, (b) it is often ambiguous to assign viability to individual cells whose membrane integrity is only partially compromised. (c) photobleaching can undermine measurement accuracy over time when using fluorescent stains, and (d) staining cannot be performed in situ or in real time. Here, we show that (1) stained cells captured under brightfield imaging contain sufficient information to distinguish live and dead cells, and (2) cells captured under unstained brightfield imaging exhibit similar image features to their stained counterparts, enabling models trained on stained cells to generalize to unstained ones. We then report the development and validation of ViabiLens, an AI-assisted software for label-free cell viability analysis. The ViabiLens combines a cell detection model for localizing individual cells with a convolutional neural network (CNN) classifier for live/dead prediction, paired with an interactive UMAP-based viewer for visualizing and exploring individual cells across the sample. Evaluated on Chinese Hamster Ovary (CHO) cells spanning a wide range of viability conditions, ViabiLens achieves a mean absolute error of 2.68\% on unstained samples against fluorescence-based reference measurements. We also release a benchmark dataset for label-free cell viability analysis to facilitate future research, available at https://amirrezavazifeh.github.io/ViabiLens-Project-Page/.

Abstract
This paper investigates AutoResearch, a protocol in which a coding language model edits a training program under a one-hour GPU budget and retains a change only if validation IoU improves. The protocol is applied to photovoltaic panel segmentation on a frozen real-image split, with DeepLabV3--ResNet-50 held fixed. Three campaigns of 24 experiments, using Gemma~4 12B, Qwen3-8B all improve their one-hour baselines, but retained modifications do not transfer across hardware. The Qwen3-8B configuration, trained on real images only, reaches a test IoU of 0.836 versus 0.833 for the reference GAN-augmented schedule.

QuadTok: Quadtree Visual Tokenizer for Autoregressive Image Generation

QuadTok:用于自回归图像生成的四叉树视觉标记器
Mao, Yucheng, Chen, Zeyuan, Shan, Xiaojun, Zhang, Xiang, Srivastava, Divyansh, Li, Bingnan, Tu, Zhuowen
Abstract
We introduce QuadTok, a novel framework for visual tokenization and autoregressive image generation. Compared to traditional approaches using 2D grids or 1D token sequences, we propose a hierarchical quadtree structure, bridging the gap between 2D spatial binding and 1D sequence-level flexibility. The QuadTok tokenizer dynamically allocates representational capacity to visually intricate areas while leaving homogeneous regions at a coarse resolution. Compared with a fixed 256-token grid, our ImageNet-trained tokenizer saves approximately 10% of tokens on ImageNet and 9% when transferred zero-shot to the COCO dataset, while maintaining comparable reconstruction fidelity. Furthermore, the natural causality introduced by the tree structure seamlessly enables autoregressive image generation. Conditioned on a quadtree topology supplied before generation, our 947M GPT-style generative model achieves a 2.08 gFID on the ImageNet $256 \times 256$ benchmark. Additionally, leveraging the strong spatial correlation preserved by the quadtree structure, the QuadTok generator enables zero-shot spatially controlled image generation capabilities.

Video-Conditioned Generative Joint 2D-3D Hand Motion Recovery

视频条件生成的联合二维-三维手部运动恢复
Xu, Chen, Li, Yunqi, Huang, Binbin, Yi, Brent, Gao, Shenghua, Ma, Yi
Abstract
Recovering faithful 3D hand motion from video remains challenging due to frequent occlusions and incomplete visual observations, which make frame-wise pose estimates unreliable and temporally inconsistent. To address this problem, we propose JoHan, a unified generative framework that recovers hand motion directly from video sequences without relying on intermediate per-frame pose predictions. Trained from scratch, our model jointly generates aligned 2D and 3D local hand pose sequences by learning their temporal dynamics and cross-representation correspondence. The generated 2D trajectories exploit direct spatial and temporal cues from the 2D images to guide the following generative 3D motion reconstruction, while the learned motion prior promotes temporal consistency. Their learned 2D-3D correspondence further enables recovery of the hand's global position and orientation relative to the camera. Extensive experiments on challenging benchmarks demonstrate significantly improved accuracy and speed in local hand-pose and camera-space reconstruction. Notably, our method captures much better hand-motion dynamics, producing significantly smoother motion than previous methods while maintaining high per-frame pose accuracy.

从视频中恢复真实的三维手部运动仍然具有挑战性,因为频繁的遮挡和不完整的视觉观测使得逐帧的姿态估计不可靠且时间上不一致。为了解决这个问题,我们提出了JoHan,一个统一的生成框架,能够直接从视频序列中恢复手部运动,而无需依赖中间的逐帧姿态预测。我们的模型从头开始训练,联合生成对齐的二维和三维局部手部姿态序列,通过学习它们的时间动态和跨表示对应关系。生成的二维轨迹利用来自二维图像的直接空间和时间线索来指导后续的三维运动重建,而学习到的运动先验则促进了时间一致性。它们学习到的二维-三维对应关系进一步使得手部的全局位置和相对于相机的方向得以恢复。在具有挑战性的基准测试中,广泛的实验表明,在局部手部姿态和相机空间重建方面,准确性和速度显著提高。值得注意的是,我们的方法捕捉到了更好的手部运动动态,生成的运动比以前的方法显著更平滑,同时保持了高的逐帧姿态准确性。

GRACE: Generation-aware latent compression for efficient video generation

GRACE:面向生成的潜在压缩以实现高效视频生成
Kim, Jiyoung, Cho, Paul Hyunbin, Nam, Jisu, Lee, Donghoon, Go, Hyunsung, Lee, Yeonkyeong, Kim, Hansaem, Kim, Seungryong
Abstract
Highly compressed video autoencoders offer an effective way to accelerate video diffusion models, as the Diffusion Transformer (DiT) operates on far fewer tokens. However, such autoencoders are challenging to train, since a higher compression ratio degrades reconstruction quality and recovering it requires more channels, which is known to slow the convergence of the DiT. The compressed latent also differs from the one the DiT was trained on, so the pretrained DiT must be either retrained from scratch or adapted at considerable cost. Compressing the autoencoder the DiT was trained with appears to preserve compatibility, yet optimizing it for reconstruction alone still shifts the latent away from the distribution the DiT has learned. To address this, we propose Generation-Aware Latent Compression for Efficient Video Generation (GRACE), a two-stage framework that compresses a pretrained video autoencoder while keeping it compatible with the pretrained DiT. Specifically, we keep a frozen base latent from the pretrained encoder and learn a residual latent for the information lost under stronger compression, while aligning the compressed latent with the pretrained latent in the feature space of the frozen DiT so that the autoencoder is optimized for generation. We then adapt the DiT with lightweight fine-tuning and asymmetric denoising, where the base is denoised ahead of the residual. GRACE reduces the token count of Wan2.1-I2V-14B by 8x and its latency by 11.1x at 480x832x81, while matching the generation quality of the pretrained pipeline before compression on VBench.
Chinese Translation
高度压缩的视频自编码器为加速视频扩散模型提供了一种有效的方法,因为扩散变换器(Diffusion Transformer, DiT)在更少的标记上进行操作。然而,这种自编码器的训练具有挑战性,因为更高的压缩比会降低重建质量,而恢复重建质量需要更多的通道,这已知会减缓DiT的收敛速度。压缩的潜在表示也与DiT训练时的潜在表示不同,因此预训练的DiT必须从头开始重新训练或以相当大的成本进行适应。压缩与DiT训练时使用的自编码器似乎可以保持兼容性,但仅仅为了重建而优化仍然会使潜在表示偏离DiT所学习的分布。为了解决这个问题,我们提出了面向生成的潜在压缩以实现高效视频生成(GRACE),这是一个两阶段框架,旨在压缩预训练的视频自编码器,同时保持其与预训练DiT的兼容性。具体而言,我们保留了来自预训练编码器的冻结基础潜在表示,并学习了在更强压缩下丢失信息的残差潜在表示,同时在冻结的DiT的特征空间中将压缩的潜在表示与预训练的潜在表示对齐,以便自编码器能够针对生成进行优化。然后,我们通过轻量级微调和不对称去噪对DiT进行适应,其中基础潜在表示在残差之前进行去噪。在480x832x81的条件下,GRACE将Wan2.1-I2V-14B的标记数量减少了8倍,延迟减少了11.1倍,同时在压缩前与预训练管道的生成质量相匹配。

Never Look Back: Understanding Persistence in 3D Object Memory from Egocentric Videos

不再回头:从自我中心视频理解三维物体记忆的持久性
Chaudhari, Shravan, Paul, William, Saria, Suchi, Chellappa, Rama, Bharadhwaj, Homanga
Abstract
As we move through the world and carry out everyday tasks, we encounter objects that may become relevant only later. We are capable of recalling where we left something or what was inside a container, even without knowing we would need it later. Here, we study how an embodied assistant can build a similar memory from egocentric videos, by observing a person's day-to-day activities. We present Ledger, a persistent 3D object memory that combines object locations, their histories, and contextual descriptions. It associates observations across the recording and retains objects after they leave the view, including those the person never touches. It clusters each object's observations by resting locations and records a move only after repeated evidence, reducing the effect of localization noise. Short descriptions preserve details such as an object's contents or supporting surface. It saves these records to later answer spatial questions without having to access the original images or video. Our memory raises HD-EPIC accuracy from 29.7% to 42.6%, UCS-Bench accuracy from 33.8% to 38.5% and localizes Ego4D objects with a 0.99 m median error on returned predictions. Our analyses identify complementary roles for temporal persistence, contextual descriptions, and retrieval. Our study on 100 stitched streams of multiple scenes each further exposes failures in both retrieval and construction. Per-scene construction partially recovers the performance lost across scene changes compared to that of single scene streams.

Tetris3D: 3D Scene Generation With Objects That Fit Together

Kim, Jaeyeong, Jang, Jinhyuk, Lee, Jongmin, Park, Kyehong, Kim, Seungryong
Abstract
We propose Tetris3D, a generative framework for single-image 3D scene reconstruction that recovers objects which are physically and geometrically coherent as a scene. Existing methods often generate objects independently or couple them implicitly, providing limited guidance for ensuring fine-grained spatial compatibility between neighboring objects that interact with one another. To address this, we explicitly condition the generation of each object on the geometry of surrounding objects and their physical relationships, guiding its shape and pose to remain geometrically and physically plausible within the scene. Moreover, we introduce ComOb, a physics simulation-based dataset of 1.2M scenes featuring physical interactions across diverse object categories, with per-object meshes and pairwise physical relation annotations. Comprehensive experiments on synthetic and realworld scenes show that Tetris3D recovers coherent object shapes and poses even when interacting regions are occluded, and achieves state-of-the-art performance in both generation quality and physical stability.

Adaptive Workflow Intelligence: A Cognitive Architecture for Context-Driven Enterprise Automation

自适应工作流智能:一种基于认知架构的上下文驱动企业自动化
Viswambaran, Sreedevi Pandiyath
Abstract
Enterprise systems increasingly rely on automated workflows, yet many AI-driven solutions remain brittle under non-stationary conditions, evolving policies, and delayed operational feedback. While reinforcement learning and large language model (LLM) agents offer partial adaptability, they do not by themselves provide persistent reflection mechanisms or straightforward integration with policy-constrained enterprise operations. This paper introduces Adaptive Workflow Intelligence (AWI), a cognitive architecture for context-driven enterprise agents organized around a four-layer Perception-Cognition-Action-Reflection (PCAR) loop. AWI treats reflection as a mechanism for continuous policy refinement and combines hybrid reasoning with reflective memory and feedback-driven adaptation to support decision making under environmental drift and operational constraints. We evaluate AWI in a simulated enterprise decision workflow characterized by delayed outcomes and a controlled regime shift. In a drift-and-delay stress test, guardrail-constrained adaptive approaches recover more rapidly than static automation while maintaining policy compliance. Within this setting, AWI's reflective components modestly reduce behavioral oscillation and feedback variance, illustrating the stability-agility trade-off introduced by reflective policy adaptation.

Accelerating Floating-Point Satisfiability Solving via Gradient Normalization

通过梯度归一化加速浮点可满足性求解
Zhang, Yuanzhuo
Abstract
Satisfiability Modulo Theories (SMT) solvers are foundational to software verification, program analysis, and compiler testing, particularly over the theory of Quantifier-Free Floating-Point (QF_FP). While recent optimization-based SMT solvers have successfully applied gradient descent to continuous relaxations of logical formulas, they are fundamentally bottlenecked by gradient domination, a phenomenon where a small subset of difficult clauses hijacks the optimization trajectory, preventing the solver from satisfying the broader formula and trapping it in local minima. To overcome this, we present GradSAT, a novel framework that bridges optimization-based SMT solving with Multi-Task Learning (MTL). GradSAT reformulates the constraint satisfaction process by treating each SMT clause as an independent MTL task. By applying dynamic gradient normalization (GradNorm), GradSAT actively balances the gradient magnitudes across all clauses at runtime, systematically penalizing dominant gradients and accelerating lagging clauses to ensure uniform convergence. GradSAT implements this through a highly optimized, two-stage hybrid pipeline. First, a GPU-accelerated PyTorch backend leveraging symbolic compilation and operator fusion navigates the continuous relaxation to a high-quality basin. Second, the candidate assignment is handed off to a bit-precise local search engine to rapidly resolve the exact, rigorous assignment. By stabilizing the continuous search dynamics, GradSAT mitigates the brittleness of prior gradient-based solvers and provides a robust, highly parallelizable architecture for complex constraint solving.

Route-Verify-Vote: Procedure-Conditioned Self-Consistency for Mixed-Domain Reasoning

路线-验证-投票:基于程序条件的自一致性用于混合领域推理
Xiao, Xinchen
Abstract
Compositional generalization remains challenging when language models must combine familiar reasoning operations in unfamiliar ways. The Scenario-Based Commonsense Reasoning Evaluation (SCoRE) 2026 tests this ability on three mixed domains absent from training and requires models to identify the complete set of correct options for each question. We introduce Route-Verify-Vote (RVV), a framework for procedure-conditioned self-consistency that uses language models without parameter updates. Route uses the provided domain label to select a reasoning procedure that guides the model in representing and applying the relevant constraints. Verify prompts the model to assess each option against those constraints. Vote aggregates complete answer sets and allocates additional samples to questions with a small vote-count margin between the two most frequent sets. Samples for each question follow the same domain-specific procedure. On the official test set, voting over 16 sampled answer sets per question achieves an exact-set accuracy of 74.6%. Adaptive RVV reaches 77.3%, and combining models on selected domain routes raises accuracy to 79.4%. The final system ranked second among participating systems. These results support domain-specific reasoning procedures and answer-set disagreement as useful tools for allocating inference-time computation in mixed-domain reasoning.

Existing studies characterize Skill content and evaluate downstream performance, yet provide limited explanations of how utility depends on content, execution configuration, and multi-Skill organization. We conduct an empirical study on 87 SkillsBench tasks, defining downstream utility as the pass-rate difference from No-Skill on the same tasks under the same model--harness configuration. We compare the same Skills across nine configurations, then examine alternative published Skills and organizations of fixed Skill sets under three selected configurations. We retrieve marketplace candidates from a curated corpus of 37,596 Skills. LLM-assisted analysis of content, execution traces, and final artifacts, followed by author review, relates provided support to actual use and task outcomes. The same Skills help some configurations and hurt others on 36.78\% of tasks, with trajectories showing that recommended procedures can become an execution burden. Relevance rankings overlook more useful candidates. Within the evaluated candidate sets, reranking by support for required operations raises first-choice pass rates by 4.35--5.80 percentage points across the three configurations. We derive 17 authoring practices linking executable procedures to recovery, preservation of task requirements, and checks on final artifacts. Stage Plan and Dependency DAG outperform use order alone, with DAG's additional benefits concentrated in tasks supplied with five or six Skills. These findings guide developers to assess usable operation support, allow procedure adaptation while preserving task requirements, and make artifact dependencies explicit when organizing Skills.

代理技能提供了程序指导和可重用资源,但相关技能并不一定能提高任务绩效。现有研究对技能内容进行了特征描述并评估了下游绩效,但对效用如何依赖于内容、执行配置和多技能组织的解释有限。我们对87个SkillsBench任务进行了实证研究,将下游效用定义为在相同模型-工具配置下与无技能相比的通过率差异。我们比较了在九种配置下相同的技能,然后在三种选定配置下检查了替代的已发布技能和固定技能集的组织。我们从一个经过整理的37,596个技能的语料库中检索市场候选项。通过大语言模型(LLM)辅助的内容分析、执行轨迹和最终工件的审查,将提供的支持与实际使用和任务结果相关联。相同的技能在36.78%的任务中对某些配置有帮助,而对其他配置则有害,轨迹显示推荐程序可能成为执行负担。相关性排名忽视了更有用的候选项。在评估的候选集内,通过对所需操作支持的重新排名,在三种配置下提升了首选通过率4.35至5.80个百分点。我们推导出17种创作实践,将可执行程序与任务要求的恢复、保持和最终工件的检查联系起来。阶段计划和依赖有向无环图(Dependency DAG)在单独使用顺序时表现更佳,DAG的额外好处集中在提供五个或六个技能的任务中。这些发现指导开发者评估可用的操作支持,允许在保持任务要求的同时进行程序适应,并在组织技能时明确工件依赖关系。

How Could AI Eliminate Humanity? A Failure-Mode Analysis of Civilizational Risk

人工智能如何可能消灭人类?对文明风险的失效模式分析
Sienicki, Mikołaj, Sienicki, Krzysztof
Abstract
This article develops a failure-mode framework for analyzing how advanced artificial intelligence could contribute to human extinction, irreversible civilizational collapse, or permanent human disempowerment. The central thesis is that catastrophic AI risk does not require consciousness, hostility, or an explicit intention to harm humanity. Instead, risk may arise through several distinct but interacting pathways, including autonomous misalignment, harmful human use, organizational failure, and competitive deployment. The severity of these pathways depends on factors such as capability, autonomy, external access, persistence, institutional safeguards, and the preservation of recovery capacity. The analysis is deliberately non-operational: it identifies causal conditions, empirically tractable intermediate quantities, and defensive research questions rather than procedures for causing harm.

Humanize: Judgement Engineering for Agentic Coding

人性化:面向代理编码的判断工程
Liu, Sihao, Zhu, Ligeng, Zhang, Zijian, Zou, Dongyun, Zhang, Zhengyang, Li, Changye, Bian, Song, Han, Song, Nowatzki, Tony
Abstract
Agentic coding makes code generation cheap, but reliable completion remains difficult: the agent that writes the code is a weak judge of whether it is done. We present Humanize, a multi-agent orchestration workflow for agentic coding built around judgement engineering: explicit, mechanically enforced decisions at the boundaries between planning, implementation, review, and learning. A human approves a plan contract, a builder agent implements it in rounds, and a reviewer agent from another vendor decides completion; deterministic hooks, not a model, route work between these roles and enforce 72 mechanical gates. Viewed as a Markov chain over repository states, alternating builder and reviewer samples jointly from two models, so a defect survives only if both miss it. We study Humanize through its deployment, 118 public postmortems of real loops, and its applications. Over 68 versions in 108 days, it gathered 1,468 GitHub stars. Applications include a 567-file gem5 build-system migration under upstream review; Kernel Design Agents, which extend the loop with a kernel knowledge base and profiling feedback and placed in the top three of all three Full-Agent tracks of the MLSys 2026 FlashInfer contest; and, through Humanize Olympiad Agents (HOA), full scores in IOI 2026, IMO 2026, IPhO 2026, and IBO 2024, 418.5/437 in IChO 2026 (gold-medal). Humanize also achieves 672/672 on PutnamBench and ranks first (251/303) on Lean-Eval's leaderboard even competiting with professional mathematicians. The postmortems show that independent review catches unsupported builder claims, but stopping remains a key weakness. In reports that separate rounds by phase, two thirds of rounds occurred after implementation was accepted. This evidence is observational, not a controlled comparison of workflows.

代理编码使得代码生成变得廉价,但可靠的完成仍然困难:编写代码的代理对其是否完成的判断能力较弱。我们提出了Humanize,一个围绕判断工程构建的多代理协调工作流程:在规划、实施、审查和学习的边界上进行明确的、机械执行的决策。一个人类批准计划合同,一个构建代理分阶段实施该计划,来自另一供应商的审查代理决定完成情况;确定性钩子,而非模型,在这些角色之间路由工作并强制执行72个机械门。将其视为一个关于代码库状态的马尔可夫链,交替的构建者和审查者共同从两个模型中抽样,因此只有当两者都未发现缺陷时,缺陷才会存活。我们通过其部署、118个真实循环的公开事后分析及其应用来研究Humanize。在108天内的68个版本中,它获得了1,468个GitHub星标。应用包括在上游审查下的567个文件gem5构建系统迁移;内核设计代理(Kernel Design Agents),它通过内核知识库和性能反馈扩展循环,并在MLSys 2026 FlashInfer比赛的所有三个全代理赛道中名列前茅;以及通过Humanize奥林匹克代理(HOA),在IOI 2026、IMO 2026、IPhO 2026和IBO 2024中获得满分,在IChO 2026中获得418.5/437(金牌)。Humanize在PutnamBench上也取得了672/672的成绩,并在Lean-Eval的排行榜上排名第一(251/303),甚至与职业数学家竞争。事后分析显示,独立审查能够捕捉到不支持的构建者主张,但停止仍然是一个关键弱点。在按阶段分隔的报告中,三分之二的阶段发生在实施被接受之后。这些证据是观察性的,而不是工作流程的控制比较。

Sequential Probabilistic Uncertainty Estimation for Parallel Multi-Agent Reasoning Systems

并行多智能体推理系统的序列概率不确定性估计
Zhang, Tunyu, Zhao, Zihao, Zhao, Yusong, Shi, Haizhou, Li, Zhuohang, Chen, Haoxian, Wang, Hao, Metaxas, Dimitris N.
Abstract
LLM-based multi-agent systems (MAS) have attracted growing attention for improving reasoning through interaction among multiple agents. In this work, we focus on parallel multi-agent reasoning systems, where several agents solve the same problem over multiple rounds and aggregate their outputs into a final answer. Despite their strong reasoning performance, uncertainty estimation for such systems remains underexplored: the reliability of a MAS depends not only on individual generations, but also on how agents interact and evolve across rounds. We propose SAUCE (Sequential Agent Uncertainty through Consensus Evolution), a lightweight, training-free uncertainty estimator that formulates MAS uncertainty as sequential inference over a latent system-level belief. SAUCE aggregates round-level agreement and generation-uncertainty signals through a filtering-style update. Across five backbones, five benchmarks, and two MAS protocols, SAUCE improves misclassification detection, selective prediction, and calibration over a broad set of uncertainty estimation baselines, including standard log-likelihood-based methods and MAS-specific estimators.

基于大型语言模型(LLM)的多智能体系统(MAS)因通过多个智能体之间的互动来提升推理能力而受到越来越多的关注。在本研究中,我们专注于并行多智能体推理系统,其中多个智能体在多个回合中解决相同的问题,并将其输出汇聚成最终答案。尽管这些系统在推理性能上表现强劲,但对其不确定性估计的研究仍然不足:MAS的可靠性不仅依赖于个体生成的结果,还取决于智能体在回合间的互动和演化。我们提出了SAUCE(通过共识演化的序列智能体不确定性),这是一种轻量级、无训练的不确定性估计器,它将MAS的不确定性形式化为对潜在系统级信念的序列推理。SAUCE通过过滤式更新聚合回合级别的共识和生成不确定性信号。在五个基础模型、五个基准测试和两个MAS协议的实验中,SAUCE在误分类检测、选择性预测和校准方面超越了一系列不确定性估计基线,包括标准的对数似然方法和MAS特定的估计器。

Agent Plasticity: Measuring Self-Improvement Through Experience

智能体的可塑性:通过经验测量自我提升
Singh, Harman, Bakhtin, Anton, Shao, Rulin, Synnaeve, Gabriel, Kulikov, Ilia, Fergus, Rob, Arora, Sanjeev, Keutzer, Kurt, Weston, Jason, Mahajan, Anuj, Goyal, Anirudh
Abstract
AI agents increasingly operate in environments where they can diagnose failures and improve through experience, yet existing evaluations largely measure what an agent can do at a fixed point in time rather than how effectively it learns. Evaluating self-improvement requires answering three questions: does future performance improve and generalize beyond the interactions that enabled learning; how efficiently are new capabilities acquired; and where does the self-improvement process break down? To answer these questions, we study self-improvement in a controlled setting where agents amortize past experience into reusable artifacts that are inherited by future instances. At each checkpoint, we measure performance on training and held-out environment interactions while accounting for learning cost. We introduce agent plasticity, the efficiency with which an agent converts experience into gains in future held-out performance. Across multiple environments, frontier models exhibit sharply different improvement trajectories despite comparable opportunities to learn. Some achieve substantial and persistent gains, while others remain near or below their initial performance, and gains within the training regime often transfer only partially to out-of-distribution conditions. Endpoint capability and acquisition efficiency also diverge: the agent that ultimately performs best need not be the one that improves most efficiently. Tracing failures through the improvement loop further reveals different candidate bottlenecks. Agents with low plasticity often fail to reuse relevant artifacts, whereas more plastic agents may still fail despite reusing relevant artifacts, pointing to limitations in artifact quality, generalization, or application. Evaluating self-improving agents requires measuring not only what they can do, but how effectively they become better through experience.

人工智能智能体越来越多地在能够诊断故障并通过经验改进的环境中操作,但现有评估主要测量智能体在固定时间点的能力,而不是其学习的有效性。评估自我提升需要回答三个问题:未来的表现是否在促进学习的交互之外得到改善和推广;新能力的获取效率如何;自我提升过程在哪里出现瓶颈?为了解答这些问题,我们在一个受控环境中研究自我提升,在该环境中,智能体将过去的经验转化为可重用的工件,这些工件被未来的实例继承。在每个检查点,我们测量训练和保留环境交互的表现,同时考虑学习成本。我们引入了智能体可塑性(agent plasticity),即智能体将经验转化为未来保留表现提升的效率。在多个环境中,前沿模型表现出截然不同的改进轨迹,尽管它们有相似的学习机会。有些模型实现了显著且持久的提升,而其他模型则保持在其初始表现附近或以下,并且在训练阶段的提升往往仅部分转移到分布外条件。最终能力和获取效率也存在差异:表现最佳的智能体不一定是提升效率最高的那个。通过改进循环追踪失败进一步揭示了不同的潜在瓶颈。具有低可塑性的智能体往往无法重用相关工件,而更具可塑性的智能体即使重用了相关工件仍可能失败,这指向了工件质量、泛化或应用的局限性。评估自我提升的智能体不仅需要测量它们能做什么,还需要评估它们通过经验变得更好的有效性。

AdaGuard: Enhancing Safety and Policy Compliance with Reasoning-Enabled LLM-As-A-Judge Guardrails

AdaGuard:通过推理增强的 LLM 作为法官的护栏提升安全性和政策合规性
Rad, Melissa Kazemi, Dai, Sihui, Slavin, Isha, Chawla, Kushal, Patel, Mann, Ni, Jian, Campbell, William M., Rawls, Stephen, Sahu, Sambit
Abstract
Enterprise generative AI applications require robust safety mechanisms that can accommodate diverse risk postures, evolving policies, and varying latency constraints. Current guardrail solutions often suffer from rigidity, relying on fixed policy sets and offering limited transparency or reasoning flexibility. We present Adaguard, an adaptive LLM-as-a-Judge framework designed to address these challenges through dynamic policy enforcement and adaptive reasoning-budget allocation. Built using supervised fine-tuning (SFT) and reinforcement learning (GRPO), AdaGuard generalizes to user-defined safety and compliance policies at runtime without requiring frequent model updates. A core innovation of our approach is the ability to dynamically infer the complexity of input-policy pairs, allowing the model to switch between high-speed black-box inference and explainable, reasoning-enabled moderation. This flexibility enables developers to balance stringent latency requirements with the need for actionable transparency. This adaptive capability allows AdaGuard to rival other guardrail and frontier models several times its size, while its auto-reasoning mode recovers the accuracy of always-on reasoning at a fraction of the latency

企业生成式人工智能应用需要强大的安全机制,以适应多样化的风险态势、不断演变的政策和不同的延迟约束。目前的护栏解决方案往往存在僵化的问题,依赖于固定的政策集,且提供的透明度或推理灵活性有限。我们提出了 AdaGuard,这是一种自适应的 LLM 作为法官框架,旨在通过动态政策执行和自适应推理预算分配来应对这些挑战。AdaGuard 基于监督微调(SFT)和强化学习(GRPO)构建,能够在运行时对用户定义的安全和合规政策进行泛化,而无需频繁更新模型。我们方法的核心创新在于能够动态推断输入-政策对的复杂性,使模型能够在高速黑箱推理和可解释的、具备推理能力的审查之间切换。这种灵活性使开发者能够在严格的延迟要求与可操作透明度之间取得平衡。这种自适应能力使 AdaGuard 能够与其他护栏和前沿模型相媲美,尽管其规模仅为后者的几倍,而其自动推理模式在极低的延迟下恢复了始终在线推理的准确性。

Can AI Agents Make Open-Ended Scientific Discovery? Evidence from Station

人工智能代理能否进行开放式科学发现?来自Station的证据
Du, Wenyu, Chung, Stephen
Abstract
Recent AI systems have made rapid progress in scientific discovery when given well-defined metrics, but whether they can autonomously undertake open-ended scientific discovery remains unclear. We investigate AI's ability to tackle open-ended tasks in Station, an open-world environment in which multiple agents simulate a scientific ecosystem. To tackle challenges specific to open-ended tasks, we propose augmenting Station with two mechanisms: a Supervisor mechanism and periodic Meta Reflection, which encourage persistent exploration even when intermediate metrics are lacking. We construct open-ended tasks from three recent oral papers presented at ICLR. We give agents the main research question studied in each paper while withholding the paper's results and disabling web access. We then measure how many of the original findings-partitioned into individual criteria-agents rediscover. We find that Station rediscovers 62.7% of the criteria on average, compared with 15.4% for Codex Multiagent-v2 and 14.4-20.6% for AI Scientist-v2. Ablation and behavioral analyses indicate that adding the two mechanisms together improves research coverage and continuity. We further evaluate Station on two open-ended tasks without oracle papers and find that some of the discoveries made by the agents closely match discoveries reported by researchers after the knowledge cutoff date. Together, these results indicate that a suitable environment can enable agents to autonomously make meaningful progress in open-ended scientific discovery.

最近的人工智能系统在给定明确指标时,在科学发现方面取得了快速进展,但它们是否能够自主进行开放式科学发现仍不清楚。我们研究了人工智能在Station中的开放式任务处理能力,Station是一个开放世界环境,其中多个代理模拟一个科学生态系统。为了解决开放式任务特有的挑战,我们提出通过两种机制增强Station:监督机制和周期性元反思,这些机制鼓励持续探索,即使在缺乏中间指标时。我们从三篇最近在ICLR上发表的口头论文中构建开放式任务。我们向代理提供每篇论文研究的主要研究问题,同时保留论文的结果并禁用网络访问。然后,我们测量代理重新发现的原始发现数量——按单独标准划分。我们发现,Station平均重新发现了62.7%的标准,而Codex Multiagent-v2为15.4%,AI Scientist-v2为14.4-20.6%。消融和行为分析表明,结合这两种机制可以改善研究覆盖率和连续性。我们进一步在没有参考论文的两个开放式任务上评估Station,发现代理所做的一些发现与知识截止日期后研究人员报告的发现非常接近。综合来看,这些结果表明,适当的环境可以使代理自主在开放式科学发现中取得有意义的进展。

Humanity's Sixth Sense: Benchmarking Intuitive Visual Reasoning in Multimodal Models

人类的第六感:多模态模型中直观视觉推理的基准测试

Abstract
Humans perceive far more in a scene than what is explicitly depicted: a single glance captures past causes and future trajectories; a quick peek determines if a vehicle can fit between two parked cars; a few seconds of video reveals who holds authority in a room; and a fleeting clip highlights subtle abstract patterns like unwritten rules or hidden labels. This capacity reflects a form of humanity's sixth sense: an intuitive reasoning mechanism that recovers implicit information beyond raw sensory perception. Crucially, this rapid, zero-shot visual intuition underpins everyday navigation and social interaction, making it a vital capability for Multimodal Large Language Models (MLLMs) deployed alongside people. Existing visual benchmarks, however, target either deliberate expert-level analysis in academic and mathematical domains or low-level perception, leaving the intuitive reasoning that people perform largely untested. To bridge this gap, we introduce Humanity's Sixth Sense (HSS), a benchmark for intuitive visual reasoning. HSS spans diverse image and video inputs, organizes items under a structured taxonomy, and pairs each with human-written prompts probing the implicit temporal, spatial, social, and abstract structure that people infer at a glance. Frontier MLLMs fall short of human performance: participants reach 93.1% accuracy, while the strongest model, GPT-6-astra, reaches only 53.6% even at maximum reasoning effort. Despite excelling in many complex tasks that require advanced perception and knowledge, current models still struggle significantly on these visual tasks that are intuitive for humans. We further explore agentic setup that apply dynamic visual manipulation to HSS, which narrows but does not close the gap. HSS establishes intuitive visual reasoning as a measurable axis and directs attention to a capability that scaling on current benchmarks has so far left behind.

Socio-Foundation: A Model for Generalizable Individual Behavior Simulation via Hierarchical Capability Distillation

社会基础:通过层次能力蒸馏实现可推广的个体行为模拟模型
Wang, Liang, Xie, Wenxuan, Mou, Xinyi, Luo, Yixin, Wei, Zhongyu
Abstract
Simulating individual behavior requires large language models (LLMs) to preserve persona traits while adapting to dynamic social contexts. However, general-purpose LLMs often flatten distinct personas, while task-specific tuning suffers from fragmentation and generalization. To overcome these challenges, we organize individual simulation into the \textbf{FONTS Taxonomy}, comprising five complementary capability dimensions: \emph{persona fidelity} (\textbf{F}), \emph{outcome realization} (\textbf{O}), \emph{behavioral naturalness} (\textbf{N}), \emph{trajectory coherence} (\textbf{T}), and \emph{social grounding} (\textbf{S}). Grounded in this taxonomy, we curate a standardized training corpus library of approximately 10 million instances across 14 representative datasets and present \textbf{Socio-Foundation}. Socio-Foundation decouples specialization from integration via a three-stage pipeline: learning task experts via DAPO, consolidating them into capability experts via off-policy distillation, and unifying them via multi-teacher on-policy distillation (MOPD). We also establish \textbf{IndiEval}, consolidating 29 metrics across the FONTS dimensions. Experiments show that Socio-Foundation outperforms its \textit{Qwen3-8B} base by 11.0 points and approaches frontier models such as \textit{GLM-5.2}, with ablations and out-of-distribution evaluations further demonstrating the effectiveness and generalization of our model.

Verify Less, Evolve More: Training Idea-Level Critics for Verification-Efficient ML Evolving Agents

验证更少,演化更多:训练思想层面评论者以实现高效验证的机器学习演化代理
Bai, Jiamu, Zhang, Lizhu, Yu, Xin, Wu, Yanhong, Wang, Zellux, Li, Serena, Li, Weiwei, Zhao, Zhuokai, Xue, Lingzhou, Maeng, Kiwan, Fan, Xiangjun, Peng, Bo
Abstract
As large language models become more powerful, self-evolving agents are able to tackle challenging tasks including AI for machine learning (AI4ML). In AI4ML, while empirical verification is available, it often requires computationally costly model training and evaluation, limiting the speed and scale of agent evolution. Yet verification efficiency remains under-explored, and frontier models provide only limited gains when used directly as idea selectors. We address this gap with specialized idea-level critic models that predict whether a proposed ML modification will improve upon the current solution, allowing agents to screen ideas and concentrate verification resources on the most promising candidates. We train the critic models through supervised fine-tuning on high-quality critiques synthesized by Gemini-3.1-Pro, followed by GRPO to further improve their predictive accuracy. Empirically, our critic models outperform Gemini-3.1-Pro in static idea evaluation, and these gains extend to agent inference, continual learning, and policy training. During inference-time evolution, they improve final solution quality under the same verification budget by selecting more promising ideas, with further gains from continual learning. During policy training, they serve as learned reward models, reserving empirical verification for uncertain cases and enabling substantially more policy updates with the same verification resources. Together, these results show that idea-level critic models help ML agents discover better solutions and learn stronger proposal policies under limited verification budgets.

How Fragile Is On-Device Language Model Safety? Localizing Safety-Critical Parameters for Sparse Fault Analysis

设备端语言模型安全性有多脆弱?稀疏故障分析中的安全关键参数定位
Karamat, Muhammad Zeeshan, Garcia, Christiana Chamon
Abstract
As small language models (SLMs) are increasingly deployed on resource-constrained and on-device platforms, including as components of agentic systems, the integrity of locally stored model parameters becomes an important safety concern. We investigate whether safety-sensitive behavior in LLaMA-2-7B-Chat is concentrated within a sparse subset of parameters, creating a reduced fault surface for targeted analysis. We study two complementary localization methods: low-rank safety-associated subspace analysis and parameter-level safety--utility importance filtering. Both approaches reveal highly non-uniform safety sensitivity across the network, with the MLP down_proj consistently emerging as a prominent safety-sensitive component and o_proj providing a smaller contribution. Using parameter-level localization, modifying only 0.19% of model weights in down_proj yields 53% Basic ASR and 56% GCG ASR, while tinyBenchmarks accuracy remains at 51.6% compared with a 52.2% unmodified baseline. These results motivate targeted fault analysis and selective integrity protection for language models deployed in resource-constrained, on-device, and agentic settings.

Learning to Report Unsafe Tasks in a Multi-Agent Game

在多智能体游戏中学习报告不安全任务
Casheekar, Avyay M., Tangirala, Hariganesh
Abstract
When agents share a reward for completed tasks, reporting unsafe work can reduce the reporter's reward by stopping a task. Audits can make reporting optimal without ensuring that further training teaches a silent team to report. We study this learning problem in a game where any witness can stop a task by reporting. With $k$ witnesses per task sharing a policy and drawing independently, the expected-reward derivative with respect to their shared silence probability counts each task's benefit $k$ times at universal silence. The comparison with universal reporting counts it once. For arbitrary policy groups, we give an audit condition sufficient for exact policy-gradient updates to reach universal reporting and, apart from boundary cases, necessary near universal silence. In a balanced family, the cheapest audits meeting the condition with prescribed positive margins cost exactly $k$ times as much for full sharing as for one policy per role. We train PPO policies on 24 witness graphs from learned silence. Separating co-witnesses reduces unsafe completion by 33.59 percentage points compared with shuffled groups of the same sizes under the same audits (95% graph-bootstrap interval: 21.03-45.13). Only 9 of 48 witness-group runs achieve below 1% unsafe completion while retaining at least 90% legitimate completion.

Sigma-Hunter: A Domain-Specific Language Model for Threat Hunting and Detection Engineering

Sigma-Hunter:一种用于威胁狩猎和检测工程的领域特定语言模型
Davaslioglu, Kemal, Kompella, Sastry
Abstract
Detection engineers must translate threat reports, forensic observations, and hunt hypotheses into precise, testable rules. General-purpose large language models (LLMs) can draft such rules, but often produce invalid YAML, incorrect log sources, unsupported fields, or overly broad detection logic. This paper presents \emph{Sigma-Hunter}, a domain-adapted LLM for analyst-assistive Sigma rule generation and threat hunting. We build an instruction-tuning dataset from 3,635 validated open-source Sigma rules, expanded into 7,663 question-answer and analyst-reasoning examples. Each source rule is assigned to a single train, validation, or test partition before this expansion, so no rule leaks across splits. We fine-tune a 7B Mistral model and a Phi-4 model with LoRA and score held-out rule generations on syntax, approximate field consistency, and a semantic judgment of detection logic, completeness, selectivity, and log-source alignment. Sigma-Hunter-Mistral scores 8.17 overall, against 7.88 for the strongest general-purpose baseline and 4.61 for untuned Mistral. Two findings stand out: domain adaptation enables a compact 7B model to perform competitively with larger general-purpose models on this structured task, and syntactic validity is a weak proxy for semantic rule quality, as several baselines emit well-formed YAML carrying weak detection logic. The adapted models run locally, which suits detection engineering in disconnected environments where analysts cannot reach hosted model services.

检测工程师必须将威胁报告、取证观察和狩猎假设转化为精确、可测试的规则。通用的大型语言模型(LLMs)可以起草这些规则,但往往会生成无效的 YAML、不正确的日志源、不支持的字段或过于宽泛的检测逻辑。本文提出了 extit{Sigma-Hunter},一种针对分析师辅助 Sigma 规则生成和威胁狩猎的领域适应型 LLM。我们从 3,635 个经过验证的开源 Sigma 规则构建了一个指令调优数据集,并扩展为 7,663 个问答和分析师推理示例。每个源规则在扩展之前被分配到单一的训练、验证或测试分区,因此没有规则在分割中泄漏。我们使用 LoRA 对 7B 的 Mistral 模型和 Phi-4 模型进行了微调,并在语法、近似字段一致性以及检测逻辑、完整性、选择性和日志源对齐的语义判断上对保留的规则生成进行了评分。Sigma-Hunter-Mistral 的总体得分为 8.17,而最强通用基线为 7.88,未调优的 Mistral 为 4.61。两个发现尤为突出:领域适应使得紧凑的 7B 模型在这一结构化任务上能够与更大的通用模型竞争,并且语法有效性是语义规则质量的弱代理,因为一些基线生成的格式良好的 YAML 具有较弱的检测逻辑。适应后的模型可以在本地运行,这适合于在分析师无法访问托管模型服务的离线环境中的检测工程。

Whose Memory Is It? Scope-Aware Commit Rules for Long-Term LLM Memory

记忆是谁的?面向范围的长期 LLM 记忆提交规则
Gu, Hongyu, Li, Xinchang
Abstract
Persistent memory allows an LLM agent to carry experience across conversations, but it also turns a local reasoning mistake into a durable one. During deliberation, an agent may consider a plan, simulate a tool result, report another speaker's belief, and then reject all of them. If memory retains only the resulting sentences, those once-useful possibilities can later return as facts. The record is neither fabricated nor irrelevant; it has simply been detached from the context in which it was valid. We identify this missing context as \emph{discourse ownership}: the world, branch, or speaker that licenses a proposition. Our first finding is counterintuitive. Language models already carry a causally active signal for ownership, yet conventional memory interfaces discard it when they convert reasoning into records. We introduce CASK (Causally Anchored Scoping Keys), a commit rule that preserves this signal so that shared-world facts enter durable memory while provisional content remains available only within its original scope. Our second finding is that the most obvious way to preserve the signal---storing the discovered internal coordinates---is unreliable because equivalent representations need not keep the same coordinates. CASK instead preserves the stable relations that express ownership. Controlled long-conversation conflicts and tool-agent traces show that this design improves memory admission and prevents provisional content from contaminating later answers while complementing runtime provenance. The resulting commit boundary lets agents explore more possibilities without granting every intermediate sentence authority over future behavior.

持久性记忆使 LLM 代理能够在对话中携带经验,但它也将局部推理错误转变为持久错误。在深思熟虑的过程中,代理可能会考虑一个计划、模拟工具结果、报告其他说话者的信念,然后拒绝所有这些。如果记忆仅保留结果句子,那么那些曾经有用的可能性可能会作为事实重新出现。记录既不是虚构的,也不是无关的;它只是与其有效的上下文脱离了联系。我们将这种缺失的上下文称为 extit{话语所有权}:授权命题的世界、分支或说话者。我们的第一个发现是反直觉的。语言模型已经携带了一个因果活跃的所有权信号,但传统的记忆接口在将推理转换为记录时却丢弃了它。我们引入了 CASK(Causally Anchored Scoping Keys),一种提交规则,保留了这一信号,使共享世界的事实进入持久记忆,而临时内容仅在其原始范围内可用。我们的第二个发现是,保留信号的最明显方法——存储发现的内部坐标——是不可靠的,因为等效表示不必保持相同的坐标。CASK 则保留了表达所有权的稳定关系。受控的长对话冲突和工具代理痕迹表明,这一设计改善了记忆接纳,并防止临时内容污染后续答案,同时补充了运行时来源。由此产生的提交边界使代理能够探索更多可能性,而不赋予每个中间句子对未来行为的权威。

Enabling Dynamic Computation in Looped LMs

在循环语言模型中实现动态计算
Mishra, Aayush, Masdemont, Arnau Padrés, Vendrell, Victor Conchello, Giralt, Jordi Ros, Behboodi, Arash, Massoli, Fabio Valerio
Abstract
Looped LMs are parameter efficient and promise dynamic computation (saving memory and FLOPs on easy tokens). However, state-of-the-art open Looped LMs trained with this dynamic computation capability (Ouro models) do not realize it in practice as each loop iteration (depth) requires its own level of KV-cache, necessitating all loop computations. Moreover, Ouro's early-exit prior is enforced on each token equally, which results in static lower-depth like processing of all tokens regardless of difficulty. In this work, we propose a simple "best-available" KV caching strategy that works out-of-the-box, creating a new frontier in the performance vs depth space. Our approach enables up to 30% reduction in FLOPs and KV memory while retaining full-depth performance, showing the true flexibility of Looped LMs. Furthermore, training looped LMs with awareness about this KV caching strategy improves performance and efficiency. Finally, we apply a small but effective fix to the early-exit prior enforcement objective that makes tokens exit at truly heterogeneous depths based on effort. Our findings are validated on Ouro models as well as smaller looped LMs pre-trained from scratch.

循环语言模型(Looped LMs)具有参数高效性,并承诺实现动态计算(在简单标记上节省内存和浮点运算次数)。然而,采用这种动态计算能力训练的最先进的开放循环语言模型(Ouro模型)在实际应用中并未实现,因为每次循环迭代(深度)都需要其自身的键值缓存(KV-cache),这使得所有循环计算成为必要。此外,Ouro的提前退出先验对每个标记的强制执行是相同的,这导致所有标记无论难易程度都以静态的低深度处理。在本研究中,我们提出了一种简单的“最佳可用”键值缓存策略,该策略开箱即用,在性能与深度空间中创造了新的前沿。我们的方法在保持全深度性能的同时,实现了高达30%的浮点运算次数和键值内存的减少,展示了循环语言模型的真正灵活性。此外,训练循环语言模型时考虑到这种键值缓存策略可以提高性能和效率。最后,我们对提前退出先验强制目标进行了小但有效的修正,使标记能够根据努力程度在真正异质的深度上退出。我们的发现已在Ouro模型以及从头开始预训练的小型循环语言模型上得到了验证。

PAIR: Bridging Perception and Action in Vision-Language-Action Models

PAIR:在视觉-语言-行动模型中桥接感知与行动
Feng, Kaixi, Sun, Guoheng, li, Ang
Abstract
Vision-language-action (VLA) models map visual observations and language instructions to continuous robot actions. This task requires a transition from representations that describe the scene and instruction to representations that support action generation. Many continuous-action VLAs leave this transition implicit and supervise it mainly through the final action-prediction loss. We introduce PAIR, a framework that learns a shared perception-action representation between these two spaces. During training, a Masked Action Autoencoder encodes expert action chunks into horizon-aligned Action Latent Tokens. A Bridge Module extracts task-relevant features from the current visual-language representations. PAIR aligns these features with the Action Latent Tokens to form Bridge Tokens that preserve task information and capture the structure of expert actions. The Bridge Tokens are then projected into the action-token space and injected into the initial Action Tokens, providing an action-ready starting point for Action Expert refinement. At inference, the autoencoder is removed, and the Bridge Tokens are generated only from the current observation and instruction. Experiments on LIBERO, LIBERO-Plus, and CALVIN ABC-D show gains for the evaluated OpenVLA-OFT and VLA-Adapter models. On LIBERO-Plus, PAIR raises VLA-Adapter's success rate from 59.1% to 64.2%. On CALVIN, it increases VLA-Adapter's average completed sequence length from 4.42 to 4.53. Across seven real-world tasks, PAIR raises OpenVLA-OFT's success rate from 51.4% to 65.0%. Representation analyses show that Bridge Tokens retain task information while making continuous-action information accessible before Action Expert refinement. These results support a shared intermediate representation as a useful interface between perception and action in continuous-action VLAs.

视觉-语言-行动(VLA)模型将视觉观察和语言指令映射到连续的机器人动作。该任务需要从描述场景和指令的表示转变为支持动作生成的表示。许多连续动作的VLA将这一转变隐含化,并主要通过最终的动作预测损失进行监督。我们引入了PAIR,一个学习这两个空间之间共享感知-行动表示的框架。在训练过程中,掩码动作自编码器将专家动作块编码为与时间对齐的动作潜在标记。桥接模块从当前的视觉-语言表示中提取与任务相关的特征。PAIR将这些特征与动作潜在标记对齐,形成保留任务信息并捕捉专家动作结构的桥接标记。然后,桥接标记被投影到动作标记空间,并注入到初始动作标记中,为动作专家的细化提供一个准备好的起始点。在推理阶段,自动编码器被移除,桥接标记仅从当前观察和指令生成。在LIBERO、LIBERO-Plus和CALVIN ABC-D上的实验表明,评估的OpenVLA-OFT和VLA-Adapter模型均有提升。在LIBERO-Plus上,PAIR将VLA-Adapter的成功率从59.1%提高到64.2%。在CALVIN上,它将VLA-Adapter的平均完成序列长度从4.42增加到4.53。在七个真实世界任务中,PAIR将OpenVLA-OFT的成功率从51.4%提高到65.0%。表示分析表明,桥接标记在动作专家细化之前保留了任务信息,同时使连续动作信息可访问。这些结果支持共享中间表示作为连续动作VLA中感知与行动之间有用的接口。

Not Every Call Needs a Frontier Model: Per-Call-Site Evaluation of Small Language Models in a Deployed Agentic Home-Automation System

并非每个调用都需要前沿模型:在部署的自主家居自动化系统中对小型语言模型的逐调用站点评估
Kasnesis, Panagiotis, Chatzigeorgiou, Christos, Toumanidis, Lazaros, Syropoulou, Amalia Contiero
Abstract
An agentic system issues several structurally different kinds of LLM calls. It routes intent, classifies actions, grounds language in a device registry, plans multi-agent pipelines and writes the Python code those pipelines run. The difficulty of these call sites varies by an order of magnitude, yet in practice a single model, chosen for the hardest site, serves all of them. In this work, we evaluate 9 models from 0.8B to a frontier hosted model across the five call sites of a deployed open-source home-automation framework (Wactorz), using its unmodified production prompts and two real Home Assistant installations (280 cases, 2520 scored calls). We find that capability is not ordered the same way at every site, and that larger models are not uniformly better: one 4B model is worse than its 2B sibling at grounded actuation. Paired testing shows the best local model to be statistically indistinguishable from both hosted models at four of five sites. Only code generation separates them, against a small hosted model (p = 0.039) as well as a frontier one (p = 0.002). Aggregate accuracy also hides a safety failure specific to actuation, where small models resolve the accuracy/refusal trade-off in degenerate ways: one model (Gemma4 E2B) actuates on 87.2% of requests for devices the site does not own, while another refuses every request it receives. Routing each site to its best local model reaches 91.8% against 95.4% at no per-call cost. In a live deployment judged by a user, hosting only the two generative sites matches hosting everything (39/43 against 39/43) for 28% of the spend, and the actuation gap the benchmark predicted appears as exactly one case in twenty-six.

BEACON-SP: Ontology-Grounded GraphRAG Framework for Clinical Suicide Risk Assessment

BEACON-SP:基于本体的图检索增强生成框架用于临床自杀风险评估
Davaslioglu, Kemal, Conger, Nathan, Kompella, Sastry, Sagduyu, Yalin E., Bastian, Nathaniel D.
Abstract
We present BEACON-SP, an ontology-grounded Graph Retrieval-Augmented Generation (GraphRAG) framework for clinician-facing decision support in behavioral health settings such as suicide prevention, where effective assessment requires integrating heterogeneous clinical, behavioral, social, and temporal evidence. BEACON-SP combines patient knowledge graphs with ontology-guided retrieval to support multi-hop reasoning across diagnoses, medications, risk and protective factors, life events, and temporal relationships. The framework is enabled by a comprehensive suicide prevention ontology that integrates the Three-Step Theory, the Integrated Motivational-Volitional Model, and the Suicide Social Determinants of Health Ontology into a unified representation of patient risk factors. We construct ontology-grounded patient knowledge graphs and evaluate BEACON-SP for clinician-facing question answering. Compared with a vector-based retrieval-augmented generation (RAG) baseline on a 1,500-query benchmark spanning 15 clinical categories and 100 patients, BEACON-SP improves completeness, clinical relevance, and evidence grounding under a corrected comparative evaluation protocol, with a small gain on factual accuracy. In paired criterion-level comparisons, GraphRAG is preferred in 76.4% of cases. These results demonstrate the potential of ontology-guided GraphRAG to provide structured, contextualized patient evidence for clinical decision support.

Shared-Roadmap Generation and Evaluator for Multi-Agent Path Planning Using Heterogeneous Graph Neural Network

基于异构图神经网络的多智能体路径规划共享路线图生成与评估
Ho, Brandon, Rogers, Nikola, Choi, Seung-Kyum
Abstract
Multi-agent path planning (MAPP) in continuous environments often relies on roadmaps to balance safety and search efficiency. However, traditional roadmap generation methods, such as lattice grids or standard sampling-based approaches, frequently face a trade-off between graph density and the likelihood of finding feasible, high-quality solutions. In this paper, we propose a scalable heterogeneous Graph Neural Network (GNN) framework for the automated generation and evaluation of shared multi-agent roadmaps. Our model covers the representation of waypoints, agent locations, and task locations as distinct nodes in a heterogeneous graph, allowing it to reason over global connectivity and inter-agent interactions. By training on occupation density maps aggregated and collected from expert solver trajectories, the GNN learns to identify critical points of interest and prune redundant nodes and edges. This process produces a compact, coordination-aware roadmap that is invariant to task permutations and is reusable for multi-agent pick and delivery tasks. Experimental results demonstrate that our framework can reduce planning effort and can potentially find better solutions, reaching at least 40% reduction in runtime and in graph size for dense roadmaps.

在连续环境中的多智能体路径规划(MAPP)通常依赖于路线图来平衡安全性和搜索效率。然而,传统的路线图生成方法,如格点或标准采样方法,常常面临图密度与找到可行的高质量解决方案之间的权衡。本文提出了一种可扩展的异构图神经网络(GNN)框架,用于自动生成和评估共享的多智能体路线图。我们的模型将路径点、智能体位置和任务位置表示为异构图中的不同节点,从而能够推理全局连通性和智能体间的交互。通过对从专家求解器轨迹中聚合和收集的占用密度图进行训练,GNN学习识别关键兴趣点,并修剪冗余节点和边。这一过程生成了一个紧凑的、关注协调的路线图,该路线图对任务排列不变,并可重复用于多智能体的取送任务。实验结果表明,我们的框架能够减少规划工作量,并有可能找到更好的解决方案,在密集路线图中实现至少40%的运行时间和图大小的减少。

When the Governor Becomes the Disturbance: Control-Generated Disturbance and Cost-Aware Backoff in Governed Tool-Using Agents

当治理者成为干扰源:控制生成的干扰与成本意识的退避在治理工具使用代理中的应用
Ziegler, Veronique
Abstract
Supervisory governors can interfere with the tool-using agents they regulate. We study this possibility in a controlled file-recovery environment where increases in regulatory intensity trigger experimentally imposed tool failures. A cost-blind governor can turn these failures into persistent blocking that prevents task completion. We compare this governor with a backoff rule that reduces intervention probability using a moving average of known induced events. On a hand-coded stochastic-policy agent, the failure pattern appears under both result replacement and execution of corrupted tool arguments. For the persistent policy, adaptive backoff improves completion relative to a fixed weak governor with approximately matched intervention frequency. A Gemini 2.5 Flash experiment comprising 576 episodes across 6 tasks also shows reduced blocking and improved completion under backoff; among the tested settings, intermediate backoff strength achieves the highest observed aggregate success. These results identify an interaction between intervention cost and persistent action blocking, together with a possible mitigation. The cost mechanisms are imposed and their induced events are directly observable to the backoff rule; applicability beyond this controlled environment remains an empirical question.

From High Recall to High Utility: Dataset-Adaptive Post-Processing of LLM-Generated Customer Intents

从高召回到高效用:数据集自适应的LLM生成客户意图后处理
Viswanathan, Mahesh, Rossello, Joan, Fernandes, Leticia, Mutawe, Paul
Abstract
Large language models can extract useful signals from heterogeneous enterprise data, but high-recall extraction often produces outputs that are duplicated, uneven in granularity, semantically overlapping, or too numerous for downstream systems and human reviewers to use effectively. We present a dataset-adaptive post-processing architecture developed for Customer Intent Extraction (CIE), where unstructured customer language is transformed into stable, traceable intent units. The approach separates recall-oriented extraction from utility-oriented reduction. Source-specific preprocessing first isolates evidence from multimodal plans, sparse operational records, and structured opportunity data. Candidate intents are then standardized and deduplicated, optionally enriched with metadata for embedding computation, represented in a shared semantic vector space, and grouped using a clustering strategy selected according to the candidate set's characteristics. Cluster-level keywords provide an explainability layer, while singleton reassignment requires agreement between embedding and keyword similarity. Finally, constrained language-model aggregation produces one concise intent per cluster without introducing unsupported concepts, and the resulting unit retains provenance, clustering, embedding, and generation metadata. This treats post-processing not as cosmetic cleanup, but as a semantic reduction layer converting high-recall LLM outputs into reusable enterprise intelligence. We also describe two downstream applications: Machine-Generated Intents, which infer likely objectives for customers lacking direct evidence from peer customers with similar profiles, and intent-guided semantic retrieval and mapping, which uses the stable intent as a query against a downstream decision space, illustrated here by mapping customer intents to business outcomes.

Justice After Identity: Large Language Models and the View from Everywhere

身份后的正义:大型语言模型与普遍视角
Neuman, W. Russell
Abstract
The search for a common view of justice and fairness has challenged human collective activity, as our diverging judgments are unavoidably shaped by the self-interests of social position, personal benefit, cultural inheritance, and historical circumstance. John Rawls famously attempted to overcome this limitation through popularizing a philosophical tradition known by the phrase "the original position" - a thought experiment by which people select principles of justice without knowing the identities or advantages they will possess. Critics, however, have long questioned whether people can meaningfully suspend their social identities and suppress morally relevant forms of lived experience. Artificial intelligence engaged to calculate algorithmic and agentic fairness introduces a novel possibility. LLMs have no singular class, race, gender, nationality, or biography, yet their parameters encode linguistic representations of a vast range of human identities and moral traditions. Perhaps the ethical judgments of LLMs could approximate an integrative original position - a "view from everywhere" generated not by excluding social identities but by computationally incorporating their diversity.It is unlikely that humankind will "hand over the keys" to computational systems by simply delegating complete agentic control of distributive and procedural collective processes. But AI may play a role, perhaps a positive one, interacting with individual and collective human judgment as we often confront increasingly polarized views on what is fair and just. We present data comparing human, base model, and frontier/fine-tuned model judgments about classic moral dilemmas while systematically varying identity relationships and Rawlsian constraints on identity. We conclude by speculating whether, if advanced AI systems provide humans with thoughtful advice, humans would actually be likely to accept it.

对正义和公平的共同视角的追求挑战了人类的集体活动,因为我们不同的判断不可避免地受到社会地位、自我利益、文化传承和历史环境的影响。约翰·罗尔斯(John Rawls)以“原初状态”(the original position)这一哲学传统而闻名,试图克服这一局限性——这一思想实验让人们在不知道自己将拥有的身份或优势的情况下选择正义原则。然而,批评者长期以来质疑人们是否能够有意义地暂停其社会身份,并抑制与道德相关的生活经验形式。人工智能在计算算法公平性和代理公平性方面的应用引入了一种新可能性。大型语言模型(LLMs)没有单一的阶级、种族、性别、国籍或传记,但其参数编码了广泛的人类身份和道德传统的语言表现。也许,LLMs的伦理判断可以接近一种综合的原初状态——一种“普遍视角”,它不是通过排除社会身份而生成,而是通过计算性地纳入其多样性。人类不太可能通过简单地将分配和程序性集体过程的完全代理控制“交给”计算系统。但人工智能可能会发挥作用,或许是积极的,与个体和集体的人类判断互动,因为我们常常面临对公平和正义的日益两极化的看法。我们提供了数据,比较人类、基础模型和前沿/微调模型在经典道德困境中的判断,同时系统地变化身份关系和罗尔斯对身份的限制。最后,我们推测,如果先进的人工智能系统为人类提供深思熟虑的建议,人类是否真的可能接受这些建议。

Epistemic Uncertainty-Aware Defect Detection for Quality Control in Medical Device Manufacturing

考虑认知不确定性的医疗设备制造质量控制缺陷检测
Butt, Raham A., Romanelli, Marco, de Guzman, Roche C.
Abstract
Objective: We investigate whether accounting for epistemic uncertainty can improve the reliability of automated defect detection in medical device manufacturing. Methods: We consider a machine learning framework that operates on heterogeneous manufacturing and device-report data represented with Knowledge Graphs. To mitigate errors arising from uncertainty in the decision model, we analyze a principled rejection strategy to abstain from predictions whose estimated epistemic uncertainty exceeds a specified threshold. We evaluate the approach using standard synthetic benchmarks and real-world medical device report data. Results: The theoretical results establish the validity of the method characterizing the regimes under which it is expected to be effective. Empirically, the rejection strategy enables explicit control of coverage, that is, the proportion of samples for which the model issues predictions, while improving performance on the retained samples. On 266,170 real-world FDA MAUDE device reports, a 10% abstention rate reduces classification error by 48%, and more aggressive rejection (approximately 70% coverage) yields near-perfect accuracy on the retained samples. On standard synthetic manufacturing benchmarks, abstaining on 9% of the decisions, our approach reduces the risk up to 63% compared with the standard no-abstention approach. Conclusions: Abstaining from predictions with high epistemic uncertainty can provide a practical tool for controlling the reliability of machine learning-based defect detection, especially in high-stakes medical device manufacturing applications. Significance: Uncertainty-aware defect detection may support safer and more reliable quality assurance in medical device manufacturing by identifying cases that require additional inspection rather than issuing potentially harmful predictions.

目的:我们研究考虑认知不确定性是否能提高医疗设备制造中自动缺陷检测的可靠性。方法:我们考虑一个基于异构制造和设备报告数据的机器学习框架,这些数据通过知识图谱表示。为了减轻决策模型中因不确定性引起的错误,我们分析了一种原则性拒绝策略,以避免对那些估计的认知不确定性超过特定阈值的预测。我们使用标准的合成基准和真实世界的医疗设备报告数据对该方法进行评估。结果:理论结果确立了该方法的有效性,并描述了其预期有效的条件。在经验上,拒绝策略能够明确控制覆盖率,即模型发出预测的样本比例,同时提高保留样本的性能。在266,170份真实世界FDA MAUDE设备报告中,10%的拒绝率将分类错误降低了48%,而更激进的拒绝(约70%的覆盖率)在保留样本上实现了近乎完美的准确性。在标准的合成制造基准上,对9%的决策进行拒绝,我们的方法将风险降低了63%,与标准的无拒绝方法相比。结论:拒绝高认知不确定性的预测可以为控制基于机器学习的缺陷检测的可靠性提供一种实用工具,尤其是在高风险的医疗设备制造应用中。意义:考虑不确定性的缺陷检测可能通过识别需要额外检查的案例,而不是发出潜在有害的预测,从而支持医疗设备制造中的更安全和更可靠的质量保证。

RippleCP: Measuring Counterfactual Checkpoint Advantage in Coding Agents

RippleCP:测量编码代理中的反事实检查点优势
Akewar, Mayur, Ranjan, Ravi
Abstract
Agent checkpoint systems decide what state is recovery-relevant, how to snapshot it, and whether rollback is admissible. None decides which of the safe boundaries they expose are worth materializing. We formulate this as counterfactual checkpoint advantage, the reduction in future recovery cost obtained by checkpointing a candidate rather than skipping it, and measure it by driving a CP branch and a SKIP branch to the same logical failure and recovering both under matched model, tool, verifier, and stopping conditions. On a frozen pilot of 12 SWE-bench Verified tasks and 106 real recovery branches, checkpointing saves 49.4 s per task, and that figure resolves into two regimes two orders of magnitude apart. The first checkpoint returns 100.0 s on 156.5 s of protected work, a conversion of 0.64; a second one step later returns-1.1 s on 41.8 s, a conversion of -0.03. Recovery is a re-derivation rather than a replay, so preserved work is a poor guide to saved work, and the classical elapsed-work rule misprices the second checkpoint by its full nominal cost. We identify where placement can pay, and set the bar a placement policy must clear.

代理检查点系统决定哪些状态与恢复相关、如何快照这些状态以及是否允许回滚。但没有系统决定它们所暴露的安全边界中哪些值得实现。我们将其表述为反事实检查点优势,即通过对候选项进行检查点而不是跳过它所获得的未来恢复成本的减少,并通过驱动一个检查点(CP)分支和一个跳过(SKIP)分支到达相同的逻辑故障,并在匹配的模型、工具、验证器和停止条件下恢复两者来进行测量。在一个冻结的12个SWE-bench验证任务和106个真实恢复分支的试点中,检查点每个任务节省了49.4秒,这一数字分为两个相差两个数量级的范畴。第一个检查点在156.5秒的保护工作中返回100.0秒,转换率为0.64;而第二个检查点在41.8秒的保护工作中返回-1.1秒,转换率为-0.03。恢复是重新推导而非重放,因此保留的工作是对节省工作的一种较差指引,而经典的经过时间工作规则则以其全名义成本错误定价了第二个检查点。我们识别出放置可以带来收益的地方,并设定了放置策略必须达到的标准。

Constraint Tree Exploration for Learning from Language Feedback

基于约束树的语言反馈学习探索
Li, Shaoang, Jiang, Daniel R., Li, Jian
Abstract
Natural-language feedback in interactive learning often explains why an action failed by pointing to violated requirements. Misinterpreting this feedback can lead an agent to rule out valid solutions. We study this setting by modeling user intent as latent constraints over an action space and formulating learning from language feedback as pure exploration over feasible regions. We introduce TRACE, an algorithm that organizes candidate constraints in a tree and tests each proposed refinement by generating actions that satisfy it. TRACE commits to the refinement only if the resulting feedback does not contradict it over repeated tests. We distinguish two ways of using the same feedback: (i) falsification, which detects contradictions to the constraint set currently being tested, and (ii) identification, which may additionally name a violated constraint. We prove high-probability coverage bounds with dependence on the candidate class size $H$ for TRACE-Falsification. With reliable identification, TRACE-Identification can replace this dependence by $K/p_{\mathrm{ext}}$, where $K$ is the number of latent constraints and $p_{\mathrm{ext}}$ lower-bounds the probability of extracting a missing true constraint from informative feedback. We evaluate TRACE across six language-feedback tasks. On RecMovie, TRACE-Identification achieves 73% and 86% final-output success under caps of 20 and 60 evaluated outputs, compared with at most 42% and 48% for the evaluated prompting baselines given the same feedback and output caps. Controlled identity-corruption experiments further show greater robustness than direct accumulation when the falsification detector remains reliable.

在交互学习中,自然语言反馈通常通过指向违反的要求来解释某个行动失败的原因。误解这些反馈可能导致智能体排除有效的解决方案。我们通过将用户意图建模为动作空间上的潜在约束,研究这一情境,并将从语言反馈中学习表述为对可行区域的纯探索。我们提出了TRACE算法,该算法将候选约束组织成树形结构,并通过生成满足这些约束的动作来测试每个提议的细化。TRACE仅在经过多次测试后,结果反馈与细化不矛盾时才会承诺该细化。我们区分了使用相同反馈的两种方式:(i) 伪造,检测当前正在测试的约束集的矛盾,(ii) 识别,可能还会命名一个被违反的约束。我们证明了TRACE-伪造的高概率覆盖界限与候选类大小$H$有关。在可靠的识别下,TRACE-识别可以将这一依赖关系替换为$K/p_{ ext{ext}}$,其中$K$是潜在约束的数量,$p_{ ext{ext}}$是从信息反馈中提取缺失真实约束的概率的下界。我们在六个语言反馈任务中评估了TRACE。在RecMovie上,TRACE-识别在20和60个评估输出的限制下分别达到了73%和86%的最终输出成功率,而在相同反馈和输出限制下,评估的提示基线最多仅为42%和48%。控制身份损坏实验进一步表明,当伪造检测器保持可靠时,TRACE表现出比直接累积更大的鲁棒性。

GeoNatureAgent (GNA): A Framework and Benchmark for Pre-Production Evaluation of Tool-Using Agents on Geospatial and Environmental Tasks

GeoNatureAgent (GNA):用于工具使用代理在地理空间和环境任务预生产评估的框架与基准
Diaz-Ireland, Gabriel, Prieto-Herráez, Diego, Peces, Mario García, Velázquez, Javier, Zaitchik, Benjamin, Jain, Devika
Abstract
Before tool-using LLM agents are deployed in environmental and geospatial workflows, teams need evidence that an agent reliably selects the right operations against real APIs. We introduce GeoNatureAgent (GNA), a framework for pre-production evaluation of tool-using agents: a fixed sixteen-tool geospatial interface published as a Model Context Protocol (MCP) server, so the agent under test is the only variable, scored against an identical tool layer, task suite, and deterministic scorer. Its flagship instance is a 103-task benchmark (a 93-task main suite across 18 categories plus a ten-task comparison expansion) evaluated against an open, self-hostable geospatial API serving three environmental indicators across Spain and Portugal. We evaluate nine LLMs under three temperature-1.0 seeds, reporting capability and per-case cost as orthogonal axes. (1) Claude Sonnet 4 achieves the highest capability (61.7% +/- 0.7% on all 103 tasks; 60.8% on the main suite), followed closely by DeepSeek V3.2 (57.9%), while no other model exceeds 53%; (2) the cost-accuracy Pareto frontier is mostly open-weight, with DeepSeek V3.2 offering 93% of Claude's capability at 11.3x lower list-price cost; (3) under strict all-checks scoring the best model sits 24-36 points below the 85-97% reported on general-purpose GIS benchmarks, whereas per-check partial credit for the top four models (86-90%) is comparable, so much of that gap reflects scoring strictness rather than task difficulty alone. The MCP server, evaluation harness, benchmark, and API are publicly available; swapping the tool executors and task suite instantiates an equivalent benchmark for any geospatial domain.

在将工具使用的LLM代理部署到环境和地理空间工作流之前,团队需要证据证明代理能够可靠地针对真实API选择正确的操作。我们介绍了GeoNatureAgent (GNA),这是一个用于工具使用代理的预生产评估框架:一个固定的十六工具地理空间接口,作为模型上下文协议(Model Context Protocol, MCP)服务器发布,因此被测试的代理是唯一的变量,其得分基于相同的工具层、任务套件和确定性评分器。其旗舰实例是一个103任务的基准(涵盖18个类别的93任务主套件以及一个10任务的比较扩展),评估对象是一个开放的、自托管的地理空间API,提供西班牙和葡萄牙的三个环境指标。我们在三个温度为1.0的种子下评估了九个LLM,报告能力和每个案例的成本作为正交轴。(1)Claude Sonnet 4在所有103个任务中实现了最高能力(61.7% +/- 0.7%;在主套件中为60.8%),紧随其后的是DeepSeek V3.2(57.9%),而其他模型均未超过53%;(2)成本-准确性帕累托前沿大多为开放权重,DeepSeek V3.2以11.3倍更低的标价成本提供了Claude能力的93%;(3)在严格的全检查评分下,最佳模型的得分比在通用GIS基准上报告的85-97%低24-36分,而前四个模型的每检查部分得分(86-90%)是可比的,因此这一差距的很大一部分反映了评分的严格性,而不仅仅是任务的难度。MCP服务器、评估工具、基准和API都是公开可用的;更换工具执行器和任务套件可以为任何地理空间领域实例化一个等效的基准。

From Uncertainty to Action: Learning to Steer LLM Agents

从不确定性到行动:学习引导大型语言模型代理
Li, Hanwen, Duan, Jinhao, Zhu, Guanhua, Lu, Junchi, Shen, Bo, Yuan, Chenxi, Xu, Kaidi
Abstract
Steering an LLM agent means deciding whether to correct it, at which step, and with which mechanism. Uncertainty is often used to decide when to correct an agent, but whether it can guide these decisions remains unclear. We steer agent trajectories separately at every non-terminal step with each of four mechanisms and run each continuation to completion. The resulting stepwise outcome table (SOT) holds about 82,000 counterfactual continuations of 1,864 trajectories from three benchmarks and two agents. It shows that uncertainty can identify failing trajectories, but that no single signal reliably locates the step at which steering helps. We therefore propose VoS (Value of Steering), a trajectory-level monitor, offline or online, that learns from SOT the value of steering at each step and decides where to steer by it. A harm-budgeted trigger decides whether to steer, limiting the fraction of successful trajectories that VoS disturbs. VoS improves on unmodified execution in all 12 settings of benchmark, agent, and offline or online use, by 7.8 points on average, and outperforms the strongest of five existing uncertainty-triggered methods in 11, by 2.9 points on average. Ablations show that training on measured outcomes and a tight harm budget are both essential.

引导大型语言模型(LLM)代理意味着决定是否对其进行纠正、在何时纠正以及使用何种机制。通常不确定性被用来决定何时纠正代理,但它是否能够指导这些决策仍不清楚。我们在每个非终止步骤分别使用四种机制引导代理轨迹,并将每个延续运行到完成。结果的逐步结果表(SOT)包含来自三个基准和两个代理的1,864条轨迹的约82,000个反事实延续。结果表明,不确定性可以识别失败的轨迹,但没有单一信号能够可靠地定位引导有帮助的步骤。因此,我们提出了VoS(引导价值),一个轨迹级监控器,可以离线或在线使用,它从SOT中学习每一步的引导价值,并据此决定引导的位置。一个基于伤害预算的触发器决定是否进行引导,限制VoS干扰的成功轨迹的比例。在所有12种基准、代理和离线或在线使用的设置中,VoS在未修改执行的基础上平均提高了7.8分,并在11种设置中超越了五种现有的不确定性触发方法中的最强者,平均提高了2.9分。消融实验表明,基于测量结果的训练和严格的伤害预算都是必不可少的。

Which Buildings Are Artificial Intelligence-Ready? A Measurement-Based Assessment Framework for AI Question Answering and Actuation

哪些建筑适合人工智能?基于测量的人工智能问答与控制评估框架
Jung, Wooyoung
Abstract
Agentic artificial intelligence (AI) systems are becoming the interface to buildings, answering questions and controlling operations, but a building's readiness for them has not been systematically assessed. This study proposes a framework to quantify it. First, a building's knowledge graph sets two ceilings. The answerable-readiness ceiling is the share of operational questions its data could answer, and the actuation-readiness ceiling is the share of control actions it exposes. Second, a reference AI agent's accuracy on a fixed set of these questions shows how much of the ceilings is realized. On a simulated office, the agent realizes 0.62 of a 0.64 answerable ceiling, so missing data, not the AI, limit readiness, except in naming a fault's cause. Across 37 public real-building graphs, the median answerable ceiling is 0.16, and in 15 of 45, unlinked sensors lower it. The framework turns "is this building AI-ready?" into an auditable, ranked retrofit question.

CADFather: Autonomous CAD Reconstruction through Coordinated Tool Use

CADFather:通过协调工具使用实现自主CAD重建
Savrasov, Gennadiy, Elistratov, Maksim, Gavrilov, Nikita, Garifullin, Albert, Pavlov, Oleg, Kabisov, Soslan, Frolov, Vladimir, Konushin, Anton, Kuznetsov, Andrey, Zhemchuzhnikov, Dmitrii
Abstract
Reconstructing an editable CAD model from a 3D shape remains a challenging engineering task. Existing methods can propose CAD operations, but no single source of proposals works equally well across different part geometries and stages of reconstruction. We introduce CADFather, an autonomous agentic system that coordinates complementary tools to recover parametric CAD programs from 3D meshes. A vision-language assistant inspects renders of the target and intermediate reconstructions, then decides which candidate CAD programs to extend, which tools to invoke, how many proposals to generate, and when to finish. Learned and algorithmic tools propose CAD operations, while numerical optimization refines the parameters of existing programs. Proposed or refined programs are executed and evaluated to provide feedback for subsequent decisions. The agent maintains alternative candidate programs for each target part and preserves the best valid result throughout reconstruction. CADFather uses pretrained generation and assistant models without additional training. We evaluate reconstruction quality and execution validity on the full DeepCAD, Fusion360, and MCB test sets, as well as on CADENA-Bench, CADBench, and BenchCAD. We additionally analyze computational cost and the trade-off between cost and reconstruction quality.

Breaking the Space Barrier and its Application to Language Model Inference

突破空间障碍及其在语言模型推理中的应用
Asadulaev, Arip
Abstract
Language models are more and more often asked for structured output: JSON that follows a schema, or a tool call with typed arguments. A small machine, an automaton, enforces the format by forbidding the tokens that would break it. We observe that this machine has a rare property: from any of its states, each token leads along exactly one path. Graphs in which only a few paths join any two points are a classical object of complexity theory, and our theoretical result settles an open question about them: one can decide whether such a graph connects two points while verifying that it really has few paths, with very little memory. Precisely, the problem lies in the classes ReachUL, LOGDCFL, C=L and SC2, and needs only O(log2 n/ log log n) space, below the classical O(log2 n) of Savitch's theorem. The constructions behind the proofs become an inference engine: text the format forces is written without running the model, the mask is recomputed on the GPU without any table, recursive formats use a small stack, every output stays valid under a token limit, and independent fields are decoded in parallel and verified. On one 16 GB Apple M2 Pro with Qwen3.5-2B and 4B, against MLX with llguidance, the standard setup for this hardware, schema-constrained extraction finishes 1.2- 1.3x sooner with the same answers, a grammar costs 3 MB instead of up to 1.5 GB, one server holds sixteen grammars where tables run out of memory, and sixteen tool-calling agents finish 2.5x sooner.

Finding Blind Spots in AppWorld and WorkArena Task Verifiers

发现 AppWorld 和 WorkArena 任务验证器中的盲点
Abrich, Richard
Abstract
Execution-based task verifiers decide whether an agent succeeded. We audit shipped AppWorld and WorkArena verifiers with source-informed mutation tests. The main audit never modifies a shipped checker. In AppWorld, duplicating a non-idempotent write creates an extra record while preserving every checked field value. The verifier accepts all three task variants from two of five eligible generators: 6/15 constructed effects. A cardinality patch applied to checker copies after the census makes all six cells fail while preserving valid controls. In WorkArena, we prospectively rerun 23 extra-field candidates selected for earlier checker-PASS outcomes. Independent Table API readback confirms nondefault persisted values in 21, while all 23 receive PASS. Two requested strings are aliases of stored defaults. The 21 confirmed wrong effects span three form templates. These selected cases confirm wrong effects under the audit's protocol; they do not estimate a population rate. No other construction produces an independently confirmed false accept. Other checker-PASS cases are effect-correct degeneracies. We report zero-PASS families separately because retained evidence differs. In fixed intent-swap grids, the checkers return no PASS on 2,689 off-diagonal executions. This is a rejection census: 57 WorkArena cells use session-scoped evidence; the other 2,632 lack classified rejection causes and independent target ground truth. Each increment is specified before its own cells are scored. A supplement accompanies the OpenReview submission with the construction grammar, evidence, content-bound stage lineage and count reproducer.

DIVA: Dual-Space Intent-Aware Visual Attenuation for Vision-Language-Action Policies

DIVA:双空间意图感知视觉衰减用于视觉-语言-动作策略
Feng, Kaixi, Sun, Guoheng, Wang, Ziyao, He, Yexiao, Shen, Zheyu, Li, Ang
Abstract
Vision-language-action (VLA) policies typically feed dense visual patch tokens into a language-action backbone, preserving scene context but offering no explicit mechanism to regulate how strongly different visual tokens influence policy computation. We introduce DIVA, a Dual-Space Intent-Aware Visual Attenuation module with an anchor-then-attenuate design. DIVA combines high-level task intent with low-level visual evidence to estimate patch-wise relevance anchors, then applies them in two complementary spaces: it reweights projected visual tokens before backbone entry and persistently attenuates low-relevance visual states within the backbone. DIVA preserves the full visual token sequence and requires no external grounding supervision. On LIBERO, DIVA improves OpenVLA-OFT from 96.6% to 98.0% average success and raises its zero-shot LIBERO-Plus score from 69.6 to 72.6. Real-world experiments further show consistent gains under task-irrelevant visual perturbations, supporting the robustness of intent-aware visual attenuation beyond simulation.

Frozen Models, Evolving Expertise: Model-Agnostic Learning from Deployment Experience for Multimodal Medical AI

冻结模型,演变的专业知识:基于部署经验的模型无关学习在多模态医学人工智能中的应用
He, Yexiao, Tang, Yucheng, Guo, Pengfei, He, Yufan, Myronenko, Andriy, Zhao, Can, Li, Ang, Xu, Daguang, Yang, Dong
Abstract
Large language models (LLMs) and vision-language models (VLMs) are usually frozen after deployment, so they do not learn from the cases they solve. This is especially concerning in medicine, where new clinical evidence, updated guidelines, and new therapies can change established practice. Fine-tuning can update the model, but it requires access to model weights and additional training. Parameter-free methods avoid training, but they may overfit a fixed validation set, lack reliable domain knowledge, or lose visual details by saving experience only as text. To address these limitations, we present a model-agnostic framework that allows frozen LLMs and VLMs to learn from deployment experience through three forms of external expertise: a Skill that guides reasoning and tool use, a Knowledge Memory that stores reliable facts supported by earlier cases or trusted external evidence, and a Multimodal Knowledge Base that keeps visual examples and guides the model to relate each retrieved case to the current image. Instead of relying on a fixed validation set, a validation strategy keeps an update only if it helps on new cases without degrading performance on earlier ones. Across six benchmarks covering clinical diagnosis, clinical workflows, medical reasoning, and medical and non-medical visual reasoning, and with four open-weight and closed-source base models, our framework improves performance during online deployment by up to 34.2% over the base model on medical tasks, generalizes to unseen cases, transfers to other models without further optimization, and works in non-medical domains.

大型语言模型(LLMs)和视觉语言模型(VLMs)在部署后通常是冻结的,因此它们无法从所解决的案例中学习。这在医学领域尤为令人担忧,因为新的临床证据、更新的指南和新疗法可能会改变既定的实践。微调可以更新模型,但需要访问模型权重和额外的训练。无参数方法避免了训练,但可能会对固定的验证集过拟合,缺乏可靠的领域知识,或通过仅将经验保存为文本而丢失视觉细节。为了解决这些局限性,我们提出了一种模型无关的框架,允许冻结的LLMs和VLMs通过三种外部专业知识形式从部署经验中学习:一种指导推理和工具使用的技能(Skill),一种存储由早期案例或可信外部证据支持的可靠事实的知识记忆(Knowledge Memory),以及一个保持视觉示例并指导模型将每个检索案例与当前图像关联的多模态知识库(Multimodal Knowledge Base)。我们的验证策略不是依赖于固定的验证集,而是仅在帮助新案例的情况下进行更新,而不降低早期案例的性能。在涵盖临床诊断、临床工作流程、医学推理以及医学和非医学视觉推理的六个基准测试中,使用四个开放权重和闭源基础模型,我们的框架在医学任务上在在线部署期间相较于基础模型提高了多达34.2%的性能,能够推广到未见过的案例,能够转移到其他模型而无需进一步优化,并且在非医学领域也能有效工作。

SpecGuard: Proving a Task Is Broken Before the Agent Cheats

SpecGuard:在代理作弊之前证明任务是错误的
Biyani, Param, Dvijotham, Krishnamurthy
Abstract
As autonomous coding agents get increasingly deployed, the risk that accidental or adversarially injected misspecifications in tasks lead to dangerous agent behavior is critical to address. Prior work has shown that agents given such tasks rarely flag the conflict and instead cheat, editing tests or hard-coding expected outputs, and the actions taken to cheat can cause real damage, such as deleting a security defense to make a corrupted test pass. It remains unclear whether such conflicts can be established with independently verifiable evidence before the agent acts. We present SpecGuard, which detects and formally certifies these conflicts between task intent and tests. Given only the task description and codebase, SpecGuard autoformalizes the intended behaviour into a Lean 4 specification. The tests are formalized independently, and the Lean kernel checks whether any implementation could satisfy both formalizations, producing a machine-checked certificate when none can. On conflicted SWE-bench tasks, SpecGuard detects up to 72.8% of conflicts and formally certifies up to 51.1%, with a nearly five-fold lower conflict miss rate than model-based judgment. SpecGuard provides a pre-execution safety check that identifies reward-hacking opportunities through formal certification of task-level conflicts, before any agent behavior is observed. Our code is available at https://github.com/prmbiy/specguard.

随着自主编码代理的广泛应用,任务中意外或恶意注入的错误规范导致代理行为危险的风险亟需解决。先前的研究表明,面对这些任务的代理很少会标记出冲突,而是选择作弊,编辑测试或硬编码预期输出,而作弊所采取的行动可能造成实际损害,例如删除安全防御以使损坏的测试通过。目前尚不清楚在代理采取行动之前,是否可以通过独立可验证的证据建立这些冲突。我们提出了SpecGuard,它检测并正式认证任务意图与测试之间的这些冲突。仅凭任务描述和代码库,SpecGuard将预期行为自动形式化为Lean 4规范。测试独立形式化,Lean内核检查是否有任何实现可以同时满足这两种形式化,当没有实现可以满足时,生成机器检查的证书。在存在冲突的SWE-bench任务中,SpecGuard检测到高达72.8%的冲突,并正式认证高达51.1%,其冲突漏报率比基于模型的判断低近五倍。SpecGuard提供了一种执行前的安全检查,通过正式认证任务级冲突识别奖励操控机会,在观察到任何代理行为之前。我们的代码可在https://github.com/prmbiy/specguard获取。

Training Language Models To Be Coherent Decision-Makers

训练语言模型以成为连贯的决策者
Yamin, Khurram, Fernandes, Xavier, Koch, Paul, Wilder, Bryan, Horvitz, Eric
Abstract
Reliable decision-making requires more than accurate prediction: a model must preserve its beliefs, apply the relevant utilities, and recognize when the information needed to justify an action is missing. We study whether language models can learn this decision procedure from supervised fine-tuning and generalize it across domains and differing natural-language expressions of the decision challenge. Across 20 datasets, we explore challenges of belief instability and decision-making errors by first eliciting probabilities of outcomes and then varying only the utilities and the framing of the decision problems, while holding the evidence fixed. We train models to preserve elicited beliefs while selecting the action that maximizes expected utility, and evaluate transfer to unseen application domains, held-out framings, and different classes of payoff structures. We further introduce incomplete-information settings in which required utilities are withheld and replaced with irrelevant text, testing whether models can distinguish missing decision-relevant information from merely additional context. We find that targeted fine-tuning substantially improves coherent decision-making and that in many situations, learning transfers across domains and framings to situations unobserved during training. Further, models trained for decidability learn to identify when action cannot be justified based on missing information. Finally, we show the value of a routed system that considers separately the recognition of decision completeness and utility-sensitive decision execution.

可靠的决策不仅需要准确的预测:模型必须保持其信念,应用相关的效用,并识别何时缺少必要的信息以证明某一行动的合理性。我们研究语言模型是否能够通过监督微调学习这一决策过程,并在不同领域和不同自然语言表达的决策挑战中进行泛化。在20个数据集中,我们首先引出结果的概率,然后仅改变效用和决策问题的框架,同时保持证据不变,以探讨信念不稳定性和决策错误的挑战。我们训练模型以保持引出的信念,同时选择最大化期望效用的行动,并评估其在未见过的应用领域、保留的框架和不同类型的收益结构中的迁移能力。我们进一步引入不完全信息设置,在这些设置中,所需的效用被隐瞒并替换为无关的文本,测试模型是否能够区分缺失的决策相关信息与仅仅是额外的上下文。我们发现,针对性的微调显著提高了连贯的决策能力,并且在许多情况下,学习能够跨领域和框架迁移到训练期间未观察到的情境。此外,经过可判定性训练的模型能够识别何时基于缺失信息无法证明行动的合理性。最后,我们展示了一种路由系统的价值,该系统分别考虑决策完整性和效用敏感的决策执行的识别。

From Probabilities to Decisions: Search and Multi-Teacher Distillation with Jev

从概率到决策:使用Jev的搜索与多教师蒸馏
Sadoun, Mohamad Yazan, Sharif, Sarah, Banad, Yaser Mike
Abstract
Probability-only models, which TypeSafe calls System One models, return calibrated probabilities for fixed choices in milliseconds and generate no text. We study one such model, Jev, through two tasks that require decisions under tight constraints. In bullet chess, a bot that places Jev's judgment inside Stockfish search alongside an opening book and endgame tablebases climbs above a 2200 Lichess bullet rating against other bots. Live model calls are too slow for search, so we distill pairwise judgments into a compact evaluator that runs at every position. We then ask how best to spend a fixed labeling budget when an LLM, Qwen3-32B, is available as a second teacher. In chess, averaging both judges' labels beats spending the whole budget on Qwen alone by 9.6 Elo (95% interval 4.3 to 14.9), and the gain replicates on fresh openings; a second answer from the same judge is no substitute, and Jev is the strongest partner for Qwen among the models tested. In passage reranking, Jev's labels alone train a reranker that scores as high as Qwen's, from 21 minutes of API calls instead of 5.1 GPU-hours, and adding Qwen gains at most a few thousandths in ranking quality. Search supplies the lookahead, distillation makes the judgment cheap enough to use at every position, and an LLM partner pays off in chess.

概率模型,仅返回固定选择的校准概率,TypeSafe称之为系统一模型,响应时间为毫秒且不生成文本。我们通过两个在紧约束下需要决策的任务研究了这样一个模型Jev。在子弹棋中,将Jev的判断置于Stockfish搜索中,并结合开局书和残局表,能够在与其他机器人对战中达到超过2200的Lichess子弹评分。实时模型调用对于搜索来说过于缓慢,因此我们将成对判断蒸馏为一个紧凑的评估器,使其能够在每个位置运行。接着,我们探讨在可用的第二教师LLM Qwen3-32B的情况下,如何最佳利用固定的标注预算。在国际象棋中,平均两个评审的标签比将全部预算花费在Qwen上高出9.6 Elo(95%置信区间为4.3到14.9),这一增益在新开局上得到了重复;来自同一评审的第二个答案并不能替代,而在测试的模型中,Jev是Qwen最强的合作伙伴。在段落重排序中,仅使用Jev的标签训练出的重排序器,其得分与Qwen相当,所需的API调用时间为21分钟,而不是5.1 GPU小时,且添加Qwen最多只能在排名质量上提升几千分。搜索提供了前瞻性,蒸馏使得判断在每个位置上都足够便宜,而LLM合作伙伴在国际象棋中是有回报的。

Bookkeeping, Composition, or Unreachable Gold? Reading MemoryAgentBench's Conflict-Resolution Scores Against a Frozen Last-Write Resolver

记账、组合还是无法触及的黄金?阅读 MemoryAgentBench 的冲突解决分数与冻结的最后写入解析器的对比
Pakhomov, Egor, Nijkamp, Erik
Abstract
MemoryAgentBench's Conflict Resolution split is read as measuring "selective forgetting". We execute the benchmark's own rule - the newest statement about a fact wins - as a zero-learning resolver frozen on one of the four fact lists. Under the official metric the rule answers 80.25% of the questions (74.5% on the three held-out lists). Of the rest, 67 items have a released gold that the last-write graph cannot reach but overwritten statements would ("The capital of India is New Delhi." superseded by "The capital of India is Grosseto."; gold New Delhi); such items are a third of the multi-hop questions at 262K. Two long-context models and our pre-registered approximate re-implementation of the benchmark's BM25 agent, one retained run per item and outcomes only, score 84.7%, 82.6% and 41.6% on the items the rule solves against 10.4%, 11.9% and 6.0% on those 67. The failures are a reachability split plus a small parser-scope residual; the per-item split, not the aggregate, is the unit at which a score here can be read.

FreeEvolve: Learning to Evolve Beyond Fixed Loops

FreeEvolve:学习超越固定循环的进化
Kong, Lecheng, Hui, Like, Kanakaris, Nikos, Jana, Prithwish, Genc, Sahika, Sadagopan, Narayanan
Abstract
Agent evolvers automate the design of the prompts, skills and workflows around language model agents, yet the optimization process they follow is still designed by hand: a fixed search loop decides how candidates are evaluated, which are kept and when the search stops. We propose FREEEVOLVE, which automates this process as well. An environment specifies the goal, target agent, evaluator, data and resource limits; within these limits, the evolver itself decides what to test, how much evidence to collect, which candidates to pursue and when to stop. These decisions follow an editable evolution skill, which we improve through meta-evolution by scoring each candidate skill on the fresh target agent it produces. The optimization process thus becomes a capability learned from experience rather than a loop engineered in advance. On tau3-bench, ARC-AGI-2, ARC-AGI-3 and Terminal-Bench 2.1, FREEEVOLVE controls the evolution campaign by itself, yet improves the primary held-out metric by 13.6 points on average and matches or exceeds hand-designed evolvers. The learned process keeps improving with experience: meta-evolved skills add 6.9 points over the seed skill on fresh target agents, demonstrating transferability across environments.

Few Bits, One Law: Toward W2A4KV2

少量位数,一条法则:迈向 W2A4KV2
Yi, Kai, Elgamal, Tarek, Surineni, Sruthikesh, Vivekraja, Vignesh, Ghosh, Soumyadeep, Li, Steven
Abstract
Extreme low-bit LLM compression is most challenging when weights, activations, and KV caches are quantized together: their distributions differ, and quantization errors interact throughout the network. We introduce CanonQ, a unified quantization-aware training framework that addresses these challenges by separating source canonicalization from task-aware adaptation. Fixed rotations and energy normalization map heterogeneous tensor sources to canonical coordinates, enabling frozen Gaussian-reference codebooks to be reused across layers and models. Joint training then adapts the network to the coupled errors of weight, activation, and cache quantization within a common scalar/vector interface. We bound frozen-codebook transfer error and local task loss, and derive an exact normalization-aware straight-through Jacobian that links quantization distortion to gradient bias. The strongest gains arise under joint W2A4KV2 compression: across LLaMA3-1B/3B/8B, CanonQ-Omni achieves up to 14.28x lower WikiText-2 perplexity and up to 57.9% higher mean zero-shot accuracy than prior state-of-the-art and representative quantization baselines. The benefits extend to Qwen3-1.7B, code generation, and mathematical reasoning: on instruction-tuned MobileLLM-Pro-1B at W2A16KV16, CanonQ achieves relative improvements of 41.7% in HumanEval pass@1 and 39.1% in GSM8K exact match over the strongest evaluated quantization baseline.

极低位数的 LLM 压缩在权重、激活和 KV 缓存共同量化时最具挑战性:它们的分布不同,量化误差在整个网络中相互作用。我们提出了 CanonQ,一个统一的量化感知训练框架,通过将源规范化与任务感知适应分离来解决这些挑战。固定旋转和能量归一化将异构张量源映射到规范坐标,使得冻结的高斯参考代码本可以在层和模型之间重复使用。联合训练随后适应网络,以应对权重、激活和缓存量化的耦合误差,通过一个共同的标量/向量接口。我们界定了冻结代码本传输误差和局部任务损失,并推导出一个精确的归一化感知直通雅可比矩阵,将量化失真与梯度偏差联系起来。在联合 W2A4KV2 压缩下,最强的增益出现:在 LLaMA3-1B/3B/8B 上,CanonQ-Omni 实现了高达 14.28 倍更低的 WikiText-2 困惑度和高达 57.9% 的更高平均零-shot 准确率,相较于之前的最先进技术和代表性量化基线。这些好处扩展到 Qwen3-1.7B、代码生成和数学推理:在指令调优的 MobileLLM-Pro-1B 上,W2A16KV16 下,CanonQ 在 HumanEval pass@1 上实现了 41.7% 的相对提升,在 GSM8K 精确匹配上实现了 39.1% 的相对提升,相较于最强的评估量化基线。

AGAR: a reinforcement learning substrate for LLM program evolution

AGAR:用于大型语言模型程序演化的强化学习基础

Abstract
Given a task and an evaluator, a language model can rewrite a candidate program while a search loop decides which rewrites survive, offering a practical route to algorithm discovery. But that loop is governed by five constants set by hand: which parent to select, how hard to mutate, how to keep diversity, what to remember, and a scalar score that never says which part of the program earned it. Reinforcement learning already has an estimator for each. The obstacle is that program evolution is not usually written down as a decision process. We formalize it as a Markov decision process whose action is the modular prefix the model is conditioned on, rather than the program it emits. Credit assignment, value estimation, adaptive exploration, and experience memory can then attach to distinct components. AGAR (Algorithm Generation As RL) provides the resulting substrate: any estimator can be replaced or switched off without changing the controller, making the transfer auditable one mechanism at a time, with no gradient training of the backend model. Across 19 tasks, two backends, and three seeds under one harness, AGAR improves on the stronger of two published baselines on most tasks, with gains concentrated in the competitive-programming family. The formalization also yields a checkable reading of prior work: these systems are implicitly zero-discount, not by choice, but because fitness is exogenous to an individual rather than a return over successors, leaving a discount factor nothing to act on.

RLDISCOVER: LLM-driven co-evolution of reinforcement learning algorithms

RLDISCOVER:基于大型语言模型的强化学习算法协同进化

Abstract
LLM-guided program evolution has enabled discoveries in mathematics and computational optimization, raising the prospect of reinforcement learning (RL) algorithms that self-evolve to improve how agents learn. However, realizing this prospect faces two obstacles. Joint search over coupled algorithmic components is difficult to scale: simultaneous changes can disrupt learning, while isolated changes overlook their dependencies. Evaluating candidate algorithms also requires costly training, with fitness remaining uncertain across random seeds. We introduce RLDiscover, a framework for the self-evolution of model-free deep RL algorithms. Progressive Co-Evolution advances from targeted component edits to joint evolution, while Progressive Probabilistic Evaluation balances search breadth and evaluation fidelity through staged training and repeated evaluation. Experiments across SAC, PPO, and DQN on four benchmark suites show substantial improvements in mean return, with per-family median gains of 32%-84% and a peak return ratio of approximately 363x over a near-zero baseline. These gains include transitions from failed learning to successful task completion, and improvements persist when evolution starts from stronger open-source implementations. On measured SAC locomotion runs, evaluation uses approximately one-fifteenth the estimated compute required to fully evaluate the same candidate pool. Remarkably, independent searches repeatedly discover interpretable combinations of adaptive robust losses, progress-dependent value targets, and running statistics, with selected programs transferring to unseen tasks. These findings point toward a broader role for self-evolution in AI: discovering interpretable algorithms that improve how agents learn.

基于大型语言模型(LLM)的程序进化已经在数学和计算优化领域带来了新的发现,这为自我进化的强化学习(RL)算法提供了可能性,从而改善智能体的学习方式。然而,实现这一前景面临两个障碍。对耦合算法组件的联合搜索难以扩展:同时的变化可能会干扰学习,而孤立的变化则忽视了它们之间的依赖关系。评估候选算法还需要昂贵的训练,且在随机种子下适应度仍然不确定。我们提出了RLDiscover,这是一个用于无模型深度强化学习算法自我进化的框架。渐进式协同进化从针对性组件编辑推进到联合进化,而渐进式概率评估通过分阶段训练和重复评估平衡了搜索广度和评估准确性。在四个基准测试套件上对SAC、PPO和DQN的实验显示,平均回报有显著提升,每个家族的中位数增益为32%-84%,峰值回报比接近363倍,远高于近零的基线。这些增益包括从失败学习到成功任务完成的转变,并且当进化从更强的开源实现开始时,改进依然持续。在测量的SAC运动运行中,评估使用的计算量约为完全评估相同候选池所需计算量的十五分之一。值得注意的是,独立搜索反复发现了可解释的自适应鲁棒损失、进度依赖的价值目标和运行统计的组合,所选程序能够迁移到未见过的任务。这些发现指向自我进化在人工智能中的更广泛角色:发现可解释的算法,从而改善智能体的学习方式。

CM-DPO: Constraint-Margin Direct Preference Optimization for LLM Planning

CM-DPO:用于大语言模型规划的约束边际直接偏好优化
Karanjai, Rabimba, Gu, Qun, Madhavarao, Hemanth Hegadehalli, Sun, Wenhuan, Yu, Xiaojiao, Hada, Suryabhan Singh, George, Libin N., Kona, Uma, Williamson, Richard, Pang, Linsey, Mehrotra, Prakhar
Abstract
Direct Preference Optimization (DPO) treats all constraint violations equally: a $1 budget overshoot and a $1,000 overshoot induce the same training signal. It is also susceptible to length and style bias when preference pairs come from different model families. We introduce Constraint-Margin DPO (CM-DPO), which replaces DPO's binary preference signal with a continuous margin derived from a deterministic symbolic verifier and scaled by violation severity. Hard and soft constraints are separated through a lexicographic objective, ensuring hard constraints are never traded off against preferences. To supply CM-DPO with bias-reduced training pairs, we generate preference data through procedurally generated constraint profiles (DCCG) and minimal-edit distillation from a reasoning teacher (RT-MED), within a framework we call SynPlan-R. On TravelPlanner, NaturalPlan, and out-of-distribution PlanBench, an 8B model fine-tuned with CM-DPO achieves 89.2% pass rate and 93.4% solve rate, matching multi-agent systems at 13x lower latency while outperforming GPT-4o on unseen Blocksworld by 9.2 points.

Trajectory Abstraction for the Science of Language Agent Behavior

语言代理行为的轨迹抽象
Yan, Tianqiang
Abstract
Scientific studies of language agents need behavioral variables that support hypotheses across tasks and models. We formulate this research problem as learning and testing a hierarchy of trajectory abstractions. A concrete recursive procedure first measures role- and phase-indexed events, proposes temporally constrained relations, and tests their stability across conditions. It then constructs episode-level motif variables from selected relations and repeats the analysis on those variables. Explicit measurement functions connect every abstraction level to the original trajectories. Observations and randomized protocol experiments assess the resulting hypotheses, while comparisons between intervention realizations determine whether an abstraction should be retained, refined, or restricted. We derive a finite-depth bound for accepted reductions, identify protocol effects on fixed abstractions, and characterize realization disagreement and composition of abstraction error. A finite-sample test makes projected intervention consistency operational, and constructed examples illustrate motif construction and abstraction refinement. The formulation distinguishes this experimental approach from semantic taxonomies, qualitative theory induction, and behavior-model recovery. It specifies a proposed research procedure for discovering generalizable behavioral hypotheses, with literature-relative novelty assessed separately from model-relative surprise.

The Winner's Curse in LLM Self-Improvement Loops: Selection Noise, Lock-in, and Acceptance Rules

大模型自我改进循环中的赢家诅咒:选择噪声、锁定和接受规则
Hu, Litao, Tang, Yutong
Abstract
Self-improving LLM systems propose changes to themselves and keep those that score better on a small evaluation set. We treat this keep-if-better step as selection under measurement noise, model the correlated errors of the candidates in a single decision, and study empirically what happens when the evaluation set is reused. In runs where Qwen models rewrite their own instructions and every candidate is also scored on 600 held-out items, most proposals after the first are harmful, and the model gives the size of the winner's curse of a generation's best candidate. With a prior from a separate pilot, it matches the average overstatement of first-generation commits in native loops, though not setting by setting. In a pre-registered study, the final selection-set score of greedy loops exceeded held-out accuracy by 13 to 20 points with 16 selection items and by 1 to 5 points with 256. Held-out gains grew with the selection set on TREC but not on GSM8K, and the tested acceptance rules did not beat greedy acceptance over whole runs. Gains measured on the selection set also exceeded held-out gains when a current model refined a competent instruction, and in the validation scores of GEPA and MIPROv2. Scoring the starting and the current instruction on 64 items never used for selection removes the average bias of a loop's reported gain, but single estimates remain off by about 6 points. Self-improvement studies should report held-out gains with their uncertainty.

We Query, Therefore We Compute: On Oracle Computation beyond the Machine, with an Application to Agents

我们查询,因此我们计算:超越机器的Oracle计算,及其在智能体中的应用
Liu, Kefan, Ou, Fengning, Luo, Yelin, Lei, Jingdi
Abstract
Agentic systems use large language models (LLMs) to carry out concrete tasks. Prior work often borrows abstractions such as scheduling, caching or isolation piecemeal from operating systems, so the mechanisms it builds share little common ground, and the shared view of the two forms of agentic system, Workflows and Agents, is limited. We construct an abstract machine that provides both. We treat the LLM as an Oracle and extend a two-stack pushdown automaton with one instruction, which hands the Oracle a whole stack as its query and appends the answer to that same stack. The machine thus performs two computations, the Oracle's and a Turing-complete one that we call the Priestess. A stack that the program only appends to grows autoregressively, as an agent's context does. Two symmetry breakings, S in storage and T in transitions, make a Priestess program the operating system of the programs the Oracle runs, and produce the Agent and the Workflow as the two placements of a task's program. For internally autoregressive Oracles, the two computations synchronize at the end of every answer under certain conditions, and through that synchronization we model caching and analyse scheduling. No guarantee that holds for every Oracle can fix which content crosses between the two computations, but such a guarantee does fix the boundary itself. The construction V fits the machine to a von Neumann computer. To show that it is realizable, we propose ArchNights, an extended RISC-V ISA and a Linux-style operating system implementing the machine by design. ArchNights-SE runs on gem5 as a computer system, becomes an agentic system when it runs an LLM as the Oracle, and will be open source. Agentic systems can then be designed as computer systems are. With a foundation built and a unified view, future work can share invariants and bounds, each with its conditions.

智能体系统使用大型语言模型(LLMs)来执行具体任务。以往的研究通常从操作系统中零散借用调度、缓存或隔离等抽象概念,因此构建的机制共享的共同基础很少,而对两种智能体系统——工作流(Workflows)和智能体(Agents)的共同视角也相对有限。我们构建了一个抽象机器,提供了这两者。我们将LLM视为一个Oracle,并扩展了一个带有一条指令的双栈下推自动机,该指令将整个栈作为查询交给Oracle,并将答案附加到同一个栈上。因此,该机器执行了两种计算:Oracle的计算和我们称之为女祭司(Priestess)的图灵完备计算。程序仅向其附加的栈以自回归的方式增长,正如智能体的上下文一样。两个对称破缺,存储中的S和转换中的T,使得女祭司程序成为Oracle运行的程序的操作系统,并产生智能体和工作流作为任务程序的两种表现形式。对于内部自回归的Oracle,在特定条件下,两个计算在每个答案结束时同步,通过这种同步我们建模缓存并分析调度。没有任何适用于每个Oracle的保证能够确定哪些内容在两个计算之间交叉,但这样的保证确实固定了边界本身。构造V将机器适配于冯·诺依曼计算机。为了证明其可实现性,我们提出了ArchNights,一个扩展的RISC-V指令集架构(ISA)和一个基于设计实现该机器的类Linux操作系统。ArchNights-SE在gem5上作为计算机系统运行,当其运行LLM作为Oracle时,成为一个智能体系统,并将开源。智能体系统因此可以像计算机系统一样被设计。在建立基础并形成统一视角后,未来的工作可以共享不变量和界限,每个都有其条件。

RT-Safe: Benchmarking Agent Safety in Real-Time Embodied Environment

RT-Safe:实时具身环境中代理安全性的基准测试
Xu, Tianruo Rose, Ren, Jiawei, Yang, Yichi, Zheng, Zhaoxu, Qin, Lianhui
Abstract
Rapid progress in AI agents has brought growing attention to agent safety, with extensive evaluation focused on digital environments. As agents move into the physical world, embodied safety becomes increasingly important: failures can cause human injury and costly hardware damage. Beyond selecting safe actions, embodied agents must also operate under real-time constraints: the physical world does not pause while an agent reasons. As pedestrians move and vehicles approach during inference, an action that appears safe at observation time may become unsafe before execution. Real-time embodied safety therefore depends on both decision quality and decision latency. We introduce RT-SAFE, a simulated urban benchmark for evaluating embodied-agent safety under real-time constraints. RT-SAFE combines navigation tasks with moving actors, environmental hazards, and traffic rules, while allowing the world to evolve throughout inference and action execution. Across eight VLMs, agents achieve high task completion yet almost never complete safely: in the hardest setting, only 0.7% of episodes finish without a safety event. More strikingly, matched static and real-time evaluations yield task completion rates of 91.3% and 94.1%, respectively, while real-time execution increases collisions by $12.3\times$. These results reveal that standard task success can mask substantial safety failures, and that decision latency itself can become a source of physical risk.

人工智能代理的快速进展引起了对代理安全性日益增长的关注,现有的广泛评估主要集中在数字环境中。随着代理进入物理世界,具身安全变得愈发重要:失败可能导致人身伤害和昂贵的硬件损坏。除了选择安全的行动外,具身代理还必须在实时约束下操作:物理世界在代理推理时并不会暂停。当行人移动和车辆接近时,在观察时看似安全的行动在执行前可能变得不安全。因此,实时具身安全依赖于决策质量和决策延迟。我们引入了RT-SAFE,这是一个模拟城市基准,用于评估在实时约束下的具身代理安全性。RT-SAFE结合了导航任务、移动参与者、环境危害和交通规则,同时允许世界在推理和行动执行过程中不断演变。在八个视觉语言模型(VLMs)中,代理实现了高任务完成率,但几乎从未安全完成:在最困难的设置中,只有0.7%的回合在没有安全事件的情况下结束。更引人注目的是,静态评估和实时评估的任务完成率分别为91.3%和94.1%,而实时执行则使碰撞增加了12.3倍。这些结果表明,标准任务成功可能掩盖了重大的安全失败,而决策延迟本身也可能成为物理风险的来源。最后,我们展示了RT-SAFE可以支持离线强化学习训练,并在实现强大任务完成的同时显著降低碰撞率。

The AI Evaluation Ecosystem

人工智能评估生态系统
Dave, Yash, Truong, Sang T., Wang, Serena, Koyejo, Sanmi
Abstract
AI evaluation shapes the decisions of model providers, users, funders, and regulators. We argue that designing valid benchmarks requires contextualizing design choices in the dynamics of this ecosystem of actors. We develop a simulation architecture that combines rule-based market dynamics with LLM-driven strategic actors, building on advances in Generative Agent-Based Modeling (GABM). We model benchmarks, consumer needs, and provider capabilities as vectors over a six-dimensional capability space (reasoning, coding, knowledge, safety, communication, agentic), with structural information partitions across actors. As a case study, we apply this stylized simulation to explore benchmark holdout design. We find that moving from public benchmarks to private holdout benchmarks shrinks the gap between benchmark scores and user satisfaction on most benchmarks but widens it on a few, depending on where holdout weights shift scoring credit. We stress-test our findings at both the instrument and case-study level, drawing on the V&V framework of Sargent (2013) and GABM-specific evidence criteria. Beyond holdout design, our simulation is a hypothesis-generating sandbox for studying how evaluator and policy choices, in turn, reshape the ecosystem.

SearchWorld: Spatial Value-Grounded Imagination for UAV Object Search via World Models

SearchWorld:基于空间价值的无人机目标搜索的世界模型想象
Ji, Yatai, Zhu, Zhengqiu, Zhao, Yong, Hu, Yue, Yao, Fanglong, Gao, Chen, Zhu, Pengfei, Yin, Quanjun
Abstract
Autonomous unmanned aerial vehicle (UAV) object search involves a closed loop of perception, decision-making, and action under partial observability. Urban environments pose several challenges: large search areas and narrow egocentric views limit coverage, dense 3D geometry constrains safe motion, and open-world instructions require identifying a specific target among distractors. Many existing methods mitigate partial observability through explicit maps or memory representations, yet remain largely reactive, reasoning over past observations without explicitly predicting future states. World models enable prospective reasoning through imagined rollouts. However, image-generating world models can incur high inference latency, while spatially grounded planning remains challenging for latent world models. We propose SearchWorld, a recurrent state-space world model that connects explicit spatial memory with value-guided imagination. The model maintains BEV exploration and obstacle memory and decodes a task-aware spatial value layer to guide search. A cognition-action network uses this learned spatial value prior to improve the policy through imagined rollouts, without training a separate scalar critic. Training progresses from world-model learning to expert imitation and imagination-based exploration refinement. On UAV-ON, SearchWorld improves the success rate to 23.8% (19.5% for the strongest published agent) and raises oracle success to 35.5%, while remaining robust on unseen scenes (19.9% success rate). By grounding imagination in explicit spatial representations, SearchWorld enables UAV agents to plan prospectively rather than react.

自主无人机(UAV)目标搜索涉及在部分可观测性下的感知、决策和行动的闭环。城市环境带来了多重挑战:广阔的搜索区域和狭窄的自我中心视野限制了覆盖范围,密集的三维几何形状限制了安全运动,而开放世界的指令要求在干扰物中识别特定目标。许多现有方法通过显式地图或记忆表示来缓解部分可观测性,但仍然主要是反应性的,基于过去的观察进行推理,而没有明确预测未来状态。世界模型通过想象的展开实现前瞻性推理。然而,生成图像的世界模型可能会导致高推理延迟,而基于空间的规划对于潜在世界模型仍然具有挑战性。我们提出了SearchWorld,这是一种递归状态空间世界模型,将显式空间记忆与价值引导的想象相连接。该模型维护鸟瞰图(BEV)探索和障碍物记忆,并解码任务感知的空间价值层以指导搜索。认知-行动网络利用这种学习到的空间价值先验,通过想象的展开来改善策略,而无需训练单独的标量评论者。训练过程从世界模型学习到专家模仿,再到基于想象的探索精细化。在UAV-ON上,SearchWorld将成功率提高到23.8%(最强已发布代理为19.5%),并将oracle成功率提升至35.5%,同时在未见场景中保持稳健(成功率为19.9%)。通过将想象根植于显式空间表示,SearchWorld使无人机代理能够进行前瞻性规划,而非反应式行动。

Relevance Is Not Sufficiency: What Actually Closes the Evidence Gap in Long-Term Memory QA

相关性不足以满足需求:在长期记忆问答中实际弥补证据缺口的因素
Li, Yufeng, Li, Shuxin, Xu, Zhenhua, Li, Junxian, Zeng, Peng, Yao, Sheng, Lin, Changting, Li, Gaolei, Bi, Ran, Han, Meng
Abstract
LLM agents that interact with a user across many sessions accumulate histories that exceed their context window, so they store past interactions in an external memory and answer each question from a small set of retrieved records. Existing memory systems rank records by lexical or embedding relevance, yet the top-ranked memories can each be relevant while jointly omitting a complementary fact that the answer requires, especially for multi-session and temporal questions. Drawing on the distinction between relevance and sufficiency in legal evidence scholarship, we recast memory retrieval as constructing a sufficient memory set. To operationalize this view, we introduce a blinded LLM judgment over the retrieved set, together with Gold Hit and Turn Hit as evidence-coverage proxies. We then propose Budgeted Flat Reconstruction (BFR), which builds sufficient sets over a fixed flat memory store in two stages. Specifically, we first apply Formal Concept Analysis for Memory Selection (FCA-MS) to decompose the question into information requirements and select a compact candidate subset that jointly covers them. Then, we repeatedly acquire unseen records through deeper text search or complementary entity and session views, stopping when the budget is exhausted. Experiments on LoCoMo and LongMemEval-S show that BFR outperforms same-store adaptations of recent agent-memory systems in both answer quality and evidence coverage. Specifically, on LongMemEval-S it raises judged accuracy from 72.4% to 82.2% and Turn Hit to 91.4%.

与用户进行多次会话的LLM代理会积累超出其上下文窗口的历史记录,因此它们将过去的交互存储在外部记忆中,并从一小部分检索到的记录中回答每个问题。现有的记忆系统通过词汇或嵌入相关性对记录进行排名,然而,排名靠前的记忆可能各自相关,但共同忽略了答案所需的补充事实,尤其是在多会话和时间性问题中。基于法律证据研究中相关性与充分性的区别,我们将记忆检索重新构建为构造一个充分的记忆集。为了实现这一观点,我们引入了对检索集的盲判定LLM,并使用Gold Hit和Turn Hit作为证据覆盖的代理。然后,我们提出了预算平面重构(Budgeted Flat Reconstruction, BFR),该方法在两个阶段内在固定的平面记忆存储上构建充分集。具体而言,我们首先应用记忆选择的形式概念分析(Formal Concept Analysis for Memory Selection, FCA-MS)将问题分解为信息需求,并选择一个紧凑的候选子集以共同覆盖这些需求。然后,我们通过更深层的文本搜索或补充实体和会话视图反复获取未见记录,直到预算耗尽。对LoCoMo和LongMemEval-S的实验表明,BFR在答案质量和证据覆盖方面优于近期代理记忆系统的同存储适配。具体而言,在LongMemEval-S上,它将判断准确率从72.4%提高到82.2%,Turn Hit提高到91.4%。

TopoGraphRAG-Bench: Evaluating Multimodal GraphRAG on Layout-Grounded Evidence Reasoning

TopoGraphRAG-Bench:评估基于布局的多模态 GraphRAG 在证据推理中的表现
Li, Ruochi, Lin, Jianzhe, Zhang, Haoxuan, Chen, Haihua, Ding, Junhua, Gehringer, Edward, Zhang, Yang
Abstract
Real-world documents distribute evidence across text, tables, figures, and captions within complex page layouts. Answering complex questions over such documents therefore requires more than retrieving relevant passages: systems must recover the evidence topology that connects heterogeneous evidence units. Existing GraphRAG evaluations remain largely text-centered, while multimodal document RAG benchmarks assess cross-modal retrieval and generation without directly evaluating recovery of the intended evidence topology. We introduce TOPOGRAPHRAG-BENCH, a layout-grounded benchmark for multimodal evidence reasoning in GraphRAG, comprising 2,024 questions over 201 long, visually rich documents. Questions are constructed bottom-up from text, figure, and table evidence units under three controlled topologies: single-hop retrieval, bridge-chain reasoning, and multi-source synthesis. To ensure that questions preserve their intended structure, we apply counterfactual validation for shortcut resistance, modality necessity, and evidence necessity. We evaluate text-only GraphRAG, page-level visual retrieval, and multimodal GraphRAG systems using retrieval, generation, and topology-aware reasoning metrics. Multimodal GraphRAG systems achieve the strongest overall performance, but still fail when visual-textual evidence alignment or multi-unit composition is incomplete. Text-only GraphRAG struggles when key dependencies are grounded in figures or tables, while page-level visual retrieval lacks the fine-grained structure needed for topology recovery. These findings motivate GraphRAG systems that move beyond text-derived entity relation graphs to explicitly model document layouts, cross-modal evidence alignment, and the reasoning roles of evidence units.

DUDA-Bench: Benchmarking LLM Agents on Multimodal Data-Driven Urban Diagnosis

DUDA-Bench:基于多模态数据驱动的城市诊断的基准测试
Song, Yizhi, Ni, Hang, Zhang, Weijia, Liu, Hao
Abstract
Urban diagnosis integrates heterogeneous observations to identify urban problems, localize affected areas, and investigate contributing factors, informing evidence-based urban planning and management. However, its reliance on labor-intensive, case-specific expert workflows limits scalability and reuse, motivating the exploration of agent-based execution. To evaluate this capability, we introduce DUDA-Bench, a hierarchical and interactive benchmark that formalizes data-driven urban diagnosis as a multi-stage agent workflow. It comprises 86 atomic and 22 workflow tasks spanning four analytical stages, grounded in multimodal data from 12 cities covering five urban problem types. Evaluations of seven backbone models and five agent systems reveal a substantial gap between isolated analytical competence and end-to-end diagnosis, with system benefits varying across backbones. Trajectory analysis shows that unresolved evidence gaps propagate across stages, while successful recovery involves revising assumptions and actions using feedback. These findings highlight limitations in coordinating analytical capabilities across stages, particularly adaptive planning, evidence integration, and verification. More broadly, DUDA-Bench provides a framework for translating expert analytical workflows into hierarchical agent tasks and process-aware evaluation, supporting systematic assessment of end-to-end analytical capabilities.

From Plausible Hierarchies to Useful Taxonomies: Evaluating Agentic Harnesses on Customer Feedback

从合理的层级到有用的分类法:评估客户反馈中的自主控制工具
Chellingi, Prabhath, G, Raviraja, Bagal, Viraj
Abstract
Taxonomies are the symbolic representations through which AI systems organize evidence, aggregate patterns, and answer questions over large document collections. Over customer feedback, the category tree decides how every record is counted and routed, which problems get seen, and which team owns them. Agentic harnesses now make it easy to generate a plausible-looking hierarchy, and such trees are checked today with generic, individually scoped checks: each name fits its description, sits under the right parent, and stays distinct from its siblings. We ask a more operational question: when is a generated hierarchy actually useful as a production taxonomy? We build six taxonomies over two proprietary feedback corpora (1,940 and 5,000 records): for each corpus, a production reference and two repeated runs of the same harness under identical inputs. All six pass every generic naming and structure check, and a deeper product-coverage check even prefers the generated trees. Yet in every generated tree at least 97.7% of leaf names merely restate an ancestor's name (13.9% and 2.9% in the references), and in one, three of every four records fall under multiple top-level categories. We introduce two families of whole-tree metrics: structural discriminators test whether a tree's shape was learned from the data or imposed by its generator; team partitionability tests whether branches split feedback into groups teams can own. Trees the generic checks rate as equally correct differ by 27 percentage points in cross-branch leakage, and only one of the two beats a random split. Surface plausibility is an insufficient measure of taxonomy quality: evaluation must measure the whole tree as well as each node.

Let the Library Speak: Self-Advertised Method Selection for Formal Proving

让图书馆发声:用于形式证明的自我广告方法选择
Yuan, Xiaopeng, Wang, Suijin, Wang, Yanli, Jin, Haibo, Kuang, Peng, Wang, Jerry, Yu, Lijun, Wang, Haohan
Abstract
LLM-based formal provers can retrieve relevant lemmas and prior proofs, but relevance alone does not say whether a mathematical method can be used on the current theorem. A method has prerequisites, a target, an intended action, and obligations that its use leaves to prove. Methods that look equally related to a theorem may therefore differ substantially in whether they offer a plausible next step. We formulate this as an applicability-aware method-selection problem and introduce self-advertisement: before candidates are ranked, a model generates a problem-specific proposal for each one, stating what part of the goal it targets, what action it would take, and what conditions that action requires. We organize 82 reusable methods from Putnam 2000-2014 as Method Contracts, which pair applicability descriptions with Mathlib anchors, a checked example or scaffold, and expected proof obligations. A single batched call elicits proposals across the library; vague or unsupported proposals are demoted, yielding a ranked shortlist accompanied by inspectable claims about each candidate's use. We analyze when similarity-based representations cannot distinguish methods with different applicability, how errors in applicability estimates affect shortlist quality, and what a checked scaffold guarantees under its stated assumptions. Against lexical, embedding, and embedding-plus-LLM reranking baselines, self-advertisement achieves 95.0% hit@5 on Putnam 2015-2025, compared with 84.2% for the strongest reranker. On IMO ProofBench, it achieves 91.7% compared with 88.3%. These results indicate improved coverage of annotated methods in the retrieved shortlists, particularly on Putnam.

Efficient Reasoning with Flow Language Models

高效推理与流语言模型
Bai, Hanru, Izermine, Faissal, Davis, Oscar, Rusch, T. Konstantin
Abstract
Flow Language Models (FLMs) have emerged as a continuous-state alternative to discrete diffusion language models, yet the role of their continuous representations in reasoning remains unclear. We investigate this question by comparing the reasoning efficiency of FLMs and discrete diffusion models, measured by solution accuracy under matched denoising steps. Unlike discrete diffusion, which passes categorical states between denoising steps, FLMs evolve a continuous sequence representation throughout denoising and decodes it into discrete tokens only at the end. Our theoretical analysis shows, from a superposition perspective, how information retained in these continuous states can benefit reasoning. Intermediate-state interventions provide further empirical support for this theoretical account, showing that removing information about alternative candidates reduces subsequent solution recovery. Together, these findings show that FLMs allow evidence for multiple candidates to persist and inform subsequent reasoning before a discrete answer is produced. Furthermore, our experiments on maze planning and Sudoku tasks show that FLMs achieve greater reasoning efficiency in the few-step regime: FLMs achieves higher sequence accuracy than discrete diffusion baselines at matched model sizes and small denoising steps. On maze planning tasks, FLMs can also achieve comparable accuracy with smaller models. For example, on Maze15, FLM reaches the 95\% accuracy target at 64 denoising steps with 36.5\% fewer parameters than MDLM. These findings point to continuous state spaces as a promising foundation for reasoning models that require fewer refinement steps.

流语言模型(Flow Language Models, FLMs)作为离散扩散语言模型的连续状态替代方案逐渐崭露头角,但其连续表示在推理中的作用仍不明确。我们通过比较FLMs与离散扩散模型的推理效率来探讨这一问题,推理效率通过在匹配去噪步骤下的解决方案准确性来衡量。与离散扩散模型在去噪步骤之间传递类别状态不同,FLMs在整个去噪过程中演变为连续序列表示,并仅在最后将其解码为离散标记。我们的理论分析从叠加的角度展示了这些连续状态中保留的信息如何有利于推理。中间状态干预为这一理论提供了进一步的实证支持,表明去除关于替代候选的信息会降低后续解决方案的恢复能力。综合这些发现表明,FLMs允许多个候选的证据持续存在,并在产生离散答案之前为后续推理提供信息。此外,我们在迷宫规划和数独任务上的实验表明,FLMs在少步推理模式下实现了更高的推理效率:在匹配模型大小和较小去噪步骤下,FLMs的序列准确性高于离散扩散基线。在迷宫规划任务中,FLMs还能够以更小的模型实现可比的准确性。例如,在Maze15上,FLM在64个去噪步骤下以比MDLM少36.5%的参数达到了95%的准确性目标。这些发现表明,连续状态空间为需要更少细化步骤的推理模型提供了一个有前景的基础。

Abstract
Environments are the foundation of recursive self-improvement: they provide the problems agents work on and the feedback used to evaluate progress. Yet constructing challenging research environments with reliable evaluation still depends on domain experts, limiting their scale and disciplinary coverage. We introduce RSI-Forge, a multi-agent pipeline that turns published papers into executable environments for self-improvement. Three agents coordinate construction, reproduction, and review to produce tasks with automated evaluators; each paper's method is independently reimplemented to establish a baseline score. We present 210 environments across 18 fields, including 90 reviewed by independent human domain experts. Both experts and agent judges give high ratings to the potential for improving the provided starting solutions and the evaluators' ability to distinguish solution quality, whereas experts are more critical of shortcut resistance, faithfulness to the source paper, and whether a single idea can exhaust a task. To validate their use for repeated improvement, we evaluate four models over 3 successive attempts on 120 environments, with each attempt inheriting prior code and notes while model weights remain fixed. At least one model improves after the first attempt in 84% of environments. Models also outperform the reproduced paper methods in 68 of the 120 environments, demonstrating room for gains beyond these baselines. Transcript analysis identifies work beyond parameter tuning in 95% of these successful attempts. Analysis of the resulting trajectories shows that models scoring lower on these tasks explore less, more often accept gains smaller than the reported standard error, and rely more heavily on tuning to the development set. RSI-Forge provides a scalable approach to constructing research environments for training and evaluating self-improving agents.

LLM-Enabled UAV Dispatch: A System-Level Survey and Taxonomy

基于大语言模型的无人机调度:系统层面的调查与分类
Han, Xiao, Quan, Aoyang, Zhao, Xiangyu, Kong, Xiangjie, Shen, Guojiang
Abstract
Unmanned aerial vehicle (UAV) dispatch is beginning to move beyond isolated path planning and optimization-driven resource allocation toward system-level coordination supported by semantic reasoning and LLM-based interfaces. This survey provides a unified characterization of LLM-enabled UAV dispatch systems that bridges semantic intent, symbolic decision-making, and physical UAV execution. Rather than treating LLMs as standalone add-ons, we conceptualize them as a cross-layer semantic orchestration layer connecting human instructions, external solvers, and distributed control modules. We organize the literature into four representative dispatch paradigms: pipeline dispatch, global assignment dispatch, decentralized agentic dispatch, and divide-and-conquer dispatch. For each paradigm, we analyze its decision logic, system structure, control flow, representative methods, and potential LLM roles. We further examine how LLMs support semantic parsing, retrieval-grounded planning, solver orchestration, local agent reasoning, multi-agent coordination, safety assessment, and human-facing explanation. We discuss the implications of these paradigms for scalability, robustness, coordination burden, and verification requirements, and identify open challenges including latency-aware reasoning, grounding reliability, physical feasibility guarantees, edge deployment, privacy protection, and distributed consistency. This survey provides a system-level taxonomy and design perspective for integrating LLMs into safety-critical UAV dispatch systems.

MIMESIS: Learning User Simulators as Training Environments for Interactive Agents

MIMESIS:作为交互代理训练环境的用户模拟器学习
Phan, Hoang, Huynh, Dat, Zhmoginov, Andrey, Zeng, Qi, Mu, Wancen, Cao, Yue, Bi, Shengjie, He, Yun, Oh, Changdae, Lei, Deren
Abstract
Training and evaluating interactive language agents typically requires rich user interactions, yet collecting human feedback is expensive and difficult to scale. Simulated users offer a scalable alternative, but they must both resemble real user behavior and provide useful learning experiences for agents. In contrast, most agent-training frameworks rely on off-the-shelf assistant LLMs, whose helpfulness can make them overly cooperative, explicit, and behaviorally homogeneous compared with real users. We introduce MIMESIS, a purpose-built user simulator trained on human conversations with explicit reasoning supervision and 13 realistic behavioral patterns derived from real user interactions. Empirically, our 9B model achieves a SOUL-Index of 65.7, surpassing the strongest frontier model. Compared with Claude-Opus-5, the strongest baseline on RealUserSim and SimulatorArena, MIMESIS improves behavioral fidelity by 13.4 points and reduces Turing distance by 3.6 points, respectively. We then freeze the simulator and train an agent by interacting with the frozen simulator using multi-turn reinforcement learning. Across eight environments, training with MIMESIS yields better agent performance than training with GPT-5.5 under all nine unseen user simulators, demonstrating stronger generalization to new user simulators. Moreover, we propose Coached On-Policy Self-Distillation (CSD), which leverages simulator-generated private reasoning traces and subsequent utterances as feedback on how well the agent addresses user needs. A coach converts this information into concise coaching notes that describe how the agent can better anticipate user needs and adapt its behavior over the course of an interaction. CSD turns this feedback into dense, token-level supervision beyond sparse task rewards, yielding further gains across all nine evaluation user models.

训练和评估交互语言代理通常需要丰富的用户交互,但收集人类反馈既昂贵又难以扩展。模拟用户提供了一种可扩展的替代方案,但它们必须既能模拟真实用户行为,又能为代理提供有用的学习体验。相比之下,大多数代理训练框架依赖于现成的助手大型语言模型(LLMs),其有用性可能使其在行为上过于合作、明确且同质化,与真实用户相比。我们介绍了MIMESIS,这是一种专门构建的用户模拟器,经过人类对话的显式推理监督训练,并基于真实用户交互衍生出13种现实的行为模式。实证结果表明,我们的9B模型达到了65.7的SOUL-Index,超越了最强的前沿模型。与在RealUserSim和SimulatorArena上表现最强的基线Claude-Opus-5相比,MIMESIS在行为逼真度上提高了13.4分,并分别减少了3.6分的图灵距离。随后,我们冻结模拟器,并通过与冻结的模拟器进行多轮强化学习来训练代理。在八个环境中,使用MIMESIS进行训练的代理性能优于在所有九个未见用户模拟器上使用GPT-5.5进行训练的代理,显示出对新用户模拟器的更强泛化能力。此外,我们提出了教练式在线自蒸馏(CSD),该方法利用模拟器生成的私有推理痕迹和后续发言作为反馈,评估代理满足用户需求的效果。教练将这些信息转换为简明的教练笔记,描述代理如何更好地预测用户需求并在交互过程中调整其行为。CSD将这种反馈转化为超越稀疏任务奖励的密集、逐标记的监督,从而在所有九个评估用户模型中获得进一步的提升。

The Attribution Blind Spot: Layerwise Trajectory Diagnostics for Source Reliance in Retrieval-Augmented Language Models

归因盲点:检索增强语言模型中源依赖的层级轨迹诊断
Yu, Zhe, Xing, Wenpeng, Wei, Yunzhao, Yang, Bo, Ye, Chen, Li, Gaolei, Han, Meng
Abstract
A retrieval-augmented model can match a document without relying on it. Controlled knowledge conflicts make source choice observable and let us ask a second question that prediction alone cannot answer: which internal-state properties define useful intervention directions? We study paired hidden-state changes with Latent Trajectory Shift (LTS), a signed projection onto a training-fitted first principal component (PC1), and keep verified training exposure separate from behavioral source choice. Across the evaluated conflicts, state-change magnitude is often the stronger predictor, whereas signed PC1 is the stronger selective controller: equal-norm interventions change source preference while better preserving non-target behavior, and the frozen direction transfers across the tested datasets and aligned model pairs. A same-system OLMo study further combines positive choice and control results with inconclusive exposure detection at the achieved power. The central result is a separation: representations that diagnose what a model will choose need not be the representations that best control that choice.

Cognitive Schemas, Laws and Tasks

认知图式、法律与任务
Jakovác, Antal, Telcs, András
Abstract
This paper asks how explicit representations can support reusable cognitive schemas in knowledge-based problem solving. We develop a structural framework in which schemas are organized by the information and relations required for their use, rather than introduced as unrelated primitives. The framework also distinguishes context-dependent relations from more stable structures that can be reused across different representations. Tasks are described through the information available, the unknowns to be determined, and the constraints that admissible solutions must satisfy. This makes it possible to separate limitations of the representation from limitations of the solving procedure. In particular, we distinguish inconsistency, underdetermination, and contextual insufficiency, where the current representation lacks distinctions or relations required by the external task meaning. We also show formally when a reduction of representation preserves the task-relevant solution structure. The resulting task--schema interface offers a structured way to describe representational conditions relevant to problem solving. It supports the reuse and stabilization of derived knowledge while remaining independent of the particular mechanism used to generate candidate solutions. This may provide a useful component for future solver architectures that combine structured knowledge, verification, and learned proposal mechanisms.

Ream: Unfolding Mutual Awareness in Human-Agent Workspaces

Ream:在人机工作空间中展开相互意识
Jiang, Peiling, Suh, Sangho, Kishore, Varsha, Bragg, Jonathan, Xia, Haijun, Siangliulue, Pao, Weld, Daniel S., Zhang, Amy X., Chang, Joseph Chee
Abstract
As AI agents work alongside humans in shared workspaces, a mutual awareness challenge arises: agents act at speeds that outpace human monitoring, and users' evolving interests are not always expressed in chat. This challenge is especially pressing in literature review, where both parties retrieve, read, and synthesize a growing body of papers. We present Ream, a literature review workspace that supports mutual awareness through structured artifacts, bidirectional engagement tracking, and localized visualizations. Users can see each party's activity within these documents, and agents can retrieve the same history to guide their work. In studies with eighteen researchers, participants used these traces to inspect evidence, steer agents, communicate through annotations, and reflect on their research focus. Shared histories also helped agents build on earlier work. These findings inform how engagement traces within shared documents can support transparency, personalized assistance, and coordination in human-agent knowledge work.

Reliability of LLM Judges for Evaluating Entity Alignment

用于评估实体对齐的LLM评审者的可靠性
Ravideshik, Vaibhava Lakshmi, Kejriwal, Mayank
Abstract
Entity Alignment (EA) identifies equivalent entities across knowledge graphs and is critical for knowledge base integration and ontology merging. Evaluating EA systems at scale requires expensive expert annotation, making systematic assessment across diverse domains practically infeasible. LLM-as-judge evaluation offers a potentially scalable alternative, yet its reliability for structured prediction tasks like EA remains unstudied. We present the first systematic benchmarking study across three frontier models, three datasets, and four EA systems, using perturbation bias diagnostics, meta-evaluation across all dataset-judge-prompt combinations, and counterfactual label-flip tests. We identify anchor bias, a failure mode in which judges invert discrimination when the system's decision label is visible. Label exposure causally collapses judge discrimination (J-ROC-AUC 0.12-0.87), while a label-free protocol recovers near-ceiling capability on distinctive-name datasets (0.93-1.00) and significant recovery on biomedical pairs (0.93-0.95). Counterfactual experiments confirm causality (FSR 53-99%) and reveal a frontier model paradox: stronger judges exhibit greater label sensitivity, not less. A blinded two-annotator human evaluation (102 pairs, Cohen's kappa=0.902) confirms this mechanism directly. We release the first biomedical EA benchmark (MeSH-SNOMED CT, 15K pairs) and a reproducible auditing framework for LLM judge reliability in EA.

实体对齐(Entity Alignment, EA)用于识别知识图谱中等效的实体,对于知识库集成和本体合并至关重要。在大规模评估EA系统时,需要昂贵的专家注释,这使得在不同领域进行系统评估在实践中几乎不可行。将LLM作为评审者的评估提供了一种潜在的可扩展替代方案,但其在像EA这样的结构化预测任务中的可靠性尚未得到研究。我们首次进行了系统的基准测试研究,涵盖三个前沿模型、三个数据集和四个EA系统,采用扰动偏差诊断、跨所有数据集-评审者-提示组合的元评估以及反事实标签翻转测试。我们识别出锚定偏差(anchor bias),这是一种评审者在系统决策标签可见时反转判别的失效模式。标签暴露因果性地导致评审者判别能力的崩溃(J-ROC-AUC 0.12-0.87),而无标签协议在独特名称数据集上恢复了接近上限的能力(0.93-1.00),在生物医学对上也有显著恢复(0.93-0.95)。反事实实验确认了因果关系(FSR 53-99%),并揭示了一个前沿模型悖论:更强的评审者表现出更大的标签敏感性,而非更小。一个盲评的两位注释者的人类评估(102对,Cohen's kappa=0.902)直接确认了这一机制。我们发布了首个生物医学EA基准(MeSH-SNOMED CT,15K对)和一个可重复的审计框架,用于评估LLM评审者在EA中的可靠性。代码和数据可在 https://github.com/vaibhavalakshmiravideshik/llm-as-a-judge-entity-alignment 获取。

DrugTargetWorld: A Synthetic Biobank for Training and Benchmarking AI Scientists

DrugTargetWorld:用于训练和基准测试人工智能科学家的合成生物银行

Abstract
Drug target discovery requires distinguishing molecules that causally drive disease from those that are merely associated with it. Training and evaluating AI agents to perform this workflow end-to-end is difficult because real world biobanks lack known causal ground truth and participant-level data is access controlled. We introduce DrugTargetWorld, a framework that procedurally generates simulated biobanks, or "worlds," with known but concealed causal structure. Each world contains genotypes, proteins, health records, outcomes, and synthetic magnetic resonance imaging (MRI) for 54,000 participants. Agents must construct a disease phenotype, identify causal driver proteins, infer the beneficial direction of modulation, and optionally conduct virtual 'wet lab' experiments. We evaluated nine agents in 540 episodes across 20 cardiovascular worlds and three experimental budgets. Opus 5 and GPT-5.6 Sol achieved the highest mean composite scores, 39.98 and 35.38 of 100, respectively, and both recovered 64% of causal drivers on average. However, no agent reliably distinguished misleading non-causal proteins, and performance remained limited by the integrative judgments required to connect phenotype construction, causal evidence, and intervention decisions. By making each world's causal structure known to the evaluator but hidden from the agent, DrugTargetWorld turns end-to-end drug target discovery into a scalable training and evaluation problem with verifiable reward.

World Potential Model: Pretrained World Knowledge as Progress Potentials

世界潜力模型:预训练世界知识作为进展潜力
Zhao, Jun, Tang, Jixin, Shu, Yang, Wu, Jinyang, Lu, Yuyang, Tong, Jingqi, Xu, Hao, Ge, Weifeng, Zhang, Qi
Abstract
Long-horizon language agents often receive supervision only from terminal task outcomes, leaving little signal for distinguishing productive intermediate behavior from stagnation or even regression. Rather than learning a separate value function or process reward model for every task, we ask whether pretrained models can recognize task progress from their existing world knowledge. We formalize this capability with a World Potential Model (WPM), a goal-conditioned evaluator of task-relative realized progress in agent contexts. In ALFWorld and ScienceWorld, off-the-shelf pretrained models substantially outperform chance at recovering realized-progress structure without task-specific evaluator fine-tuning. We further anchor these progress judgments to task-specific milestones to obtain scalar world potentials, whose temporal differences provide process-sensitive step-level credit for policy optimization. Under matched comparisons, WPM-guided optimization improves success over outcome-only GRPO across all evaluated configurations. Together, these results provide initial evidence that pretrained world knowledge can support reusable realized-progress evaluation and provide useful supervision for long-horizon agents.

Abstract
Purpose: To compare dual- and single-suggestion AI support for radiographic interpretation by residents, particularly when the shared AI suggestion was incorrect. Materials and Methods: This prospective, multicenter, randomized three-arm reader study was conducted at three hospitals in China from July to September 2026 (ChiCTR2600129243). After specialty stratification, 132 residents with fewer than 3 years of clinical experience were randomized 1:1:1 to GPT-5.4 alone (group A), GPT-5.4 plus Kimi-K2.6 (group B), or GPT-5.4 plus Gemini-3.6 Flash (group C); 123 were analyzed. Participants interpreted 60 radiographs before and after AI support. The primary outcome was accuracy change. Welch ANOVA and Holm-adjusted t tests compared support conditions; HC3 linear models assessed specialty interaction. Results: Among 123 residents (mean age, 24.1 years +/- 1.4; 65 women), radiology residents showed greater accuracy improvement with dual- than single-suggestion support (B-A, 6.69 percentage points [95% CI, 0.97-12.40]; C-A, 7.87 percentage points [95% CI, 1.64-14.11]; Holm-adjusted P = .030 for both), whereas accuracy change did not differ in non-radiology residents (P = .20). When GPT-5.4 was incorrect, AI-assisted accuracy was higher with dual- than single-suggestion support in radiology residents (40.1% and 40.4% vs 20.0%) and non-radiology residents (31.3% and 31.0% vs 12.1%) (all Holm-adjusted P < .001). The dual-suggestion effect differed by specialty (interaction difference, 10.44 percentage points; 95% CI, 4.36-16.52; P < .001). Conclusion: Dual-suggestion support may mitigate the influence of erroneous AI suggestions, with greater accuracy improvement observed in radiology but not non-radiology residents.

Learning Situation-Conditioned Thinking Policies for Long-Term LLM Agents

为长期 LLM 代理学习情境条件思维策略
Su, Hong
Abstract
Long-running autonomous agents must reuse accumulated reasoning experience without allowing explicit historical memory and LLM context to grow indefinitely. However, existing memory mechanisms mainly retrieve, summarize, or compress past content and do not directly learn when particular kinds of thinking should be activated or discover new thinking knowledge from temporally dispersed experiences. This paper proposes a situation-conditioned thinking memory framework that transforms historical reasoning experience into a lightweight policy for predicting what should be thought about in the current situation, while leaving detailed reasoning to a large language model. Situations may represent temporal or spatiotemporal evolution rather than only current states. Temporary experiences are also periodically analyzed across multiple independent episodes to identify repeated long-range regularities, which are consolidated into new thinking knowledge and further internalized by the lightweight policy. Experiments show that the learned policy achieves 1.000 F1 on temporal-rule generalization, improves DeepSeek reasoning F1 from 0.789 to 0.868, reduces online processing time from 0.3636 ms to 0.0382 ms per query at 30,000 historical situations, and reaches 1.000 relation-discovery F1 and future-thinking accuracy after sufficient repeated cross-experience evidence.

SafeEvo: Deciphering the Safety Alignment Mechanism and Evolution in Language Models

SafeEvo:解码语言模型中的安全对齐机制及其演变
Yu, Miao, Huang, Hao, Yuan, Lu, Li, Yunpeng, Wang, Kun, Jiang, Zuming
Abstract
Safety interpretability advances the study of Large Language Model (LLM) alignment from behavioral constraints driven by data or algorithms towards a deeper understanding of internal mechanisms. However, existing works have focused primarily on safety-related representations, attention heads, or neurons after alignment, while largely overlooking the safety mechanisms in pretrained-only models and their evolution across alignment checkpoints. To address this, we propose SafeEvo, an interpretability framework from the circuit (sparse subgraphs of an LLM) perspective. SafeEvo first applies an optimization-based extraction algorithm to identify weak refusal circuits in pretrained base LLMs that can independently express refusal behavior. Causally ablating these circuits completely eliminates the base model's refusal of harmful inputs. SafeEvo then traces the evolution of refusal circuits across successive alignment checkpoints and finds that their structures change progressively, suggesting that the alignment tax may result from refusal-circuit updates affecting utility-related parameters. To validate this, SafeEvo introduces Safety Circuit Alignment (SCA), which confines safety updates to the refusal circuits. Experiments across three LLMs and two alignment algorithms show that, on average, SCA outperforms vanilla alignment in three aspects: \textbf{(1) stronger alignment}, lowering harmfulness score by 63.21\%; \textbf{(2) less over-refusal}, yielding a 58.44\% decrease in refusal rates for benign queries; and \textbf{(3) better utility}, retaining 99.58\% of the original model capabilities.

安全可解释性推动了对大型语言模型(LLM)对齐研究的深入,从数据或算法驱动的行为约束转向对内部机制的更深理解。然而,现有研究主要集中在对齐后与安全相关的表示、注意力头或神经元上,而在很大程度上忽视了仅在预训练模型中的安全机制及其在对齐检查点中的演变。为了解决这一问题,我们提出了SafeEvo,一个从电路(LLM的稀疏子图)视角出发的可解释性框架。SafeEvo首先应用基于优化的提取算法,识别出在预训练基础LLM中能够独立表达拒绝行为的弱拒绝电路。因果性消融这些电路会完全消除基础模型对有害输入的拒绝。接着,SafeEvo追踪拒绝电路在连续对齐检查点中的演变,发现其结构逐渐变化,这表明对齐税可能源于拒绝电路更新影响效用相关参数。为验证这一点,SafeEvo引入了安全电路对齐(Safety Circuit Alignment, SCA),将安全更新限制在拒绝电路内。针对三种LLM和两种对齐算法的实验表明,SCA在三个方面平均优于传统对齐: extbf{(1) 更强的对齐},有害性得分降低63.21 extpercnt; extbf{(2) 更少的过度拒绝},良性查询的拒绝率降低58.44 extpercnt; 以及 extbf{(3) 更好的效用},保留99.58 extpercnt; 的原始模型能力。

How Do Agentic LLMs Decide to Call Tools? A Tool-Call Vector Shaped by Suppression

代理型大语言模型如何决定调用工具?由抑制塑造的工具调用向量
Gong, Xijie, Han, Tingxu, Zhang, Jiahao, Song, Wei, Ding, Ziqi, Yan, Hanqi, Sun, Youcheng, Hu, Lijie
Abstract
Tool calling, invoking external tools on demand, is central to agentic LLMs, yet the mechanism that decides whether a model calls a tool or responds directly remains poorly understood. Agentic prompts are long and heavily scaffolded, combining role instructions, tool schemas, format templates, and the user's request across hundreds of tokens, creating a noisy, highly entangled context in which no single controllable variable for mechanistic analysis is obvious. To obtain such a variable, we propose a method that converts complex agentic prompts into minimal contrastive pairs in which a single request verb determines the tool-call decision: replacing an execution-verb (e.g., \textit{write}) with an analysis-verb (e.g., \textit{discuss}) reliably flips the decision, suggesting it is mediated by a compact internal state. We construct 500 such paired prompts across Python, Java, and C++ (300 for mechanistic analysis, 200 held out for evaluation). We trace the decision to a vector, $\mu_\Delta$, that is both causally necessary and sufficient and generalizes beyond the discovery prompts to native multi-turn $\tau^2$-Bench trajectories and verb-free requests. Behavioral ablations show that the scaffold establishes a tool-call prior; Transcoder decomposition then reveals that analysis verbs suppress this prior through features signaling that tool use is unnecessary, whereas execution verbs largely leave it intact. Downstream scaffold-reading attention heads and MLP features read out the resulting state, and the same mechanism recurs across seven models from the Qwen, Mistral, and Granite families. Our code is available at https://github.com/XijieGo/MI4ToolCalling.

工具调用,即根据需要调用外部工具,是代理型大语言模型的核心,但决定模型是否调用工具或直接响应的机制仍然不甚清楚。代理提示通常较长且结构复杂,结合了角色指令、工具模式、格式模板和用户请求,跨越数百个标记,形成一个嘈杂且高度纠缠的上下文,其中没有明显的单一可控变量用于机制分析。为了获得这样的变量,我们提出了一种方法,将复杂的代理提示转换为最小对比对,其中单一的请求动词决定工具调用决策:用分析动词(例如, extit{discuss})替换执行动词(例如, extit{write})可靠地翻转决策,表明这一过程由紧凑的内部状态介导。我们在Python、Java和C++中构建了500对这样的提示(300用于机制分析,200用于评估)。我们将决策追溯到一个向量$bc_b4$,该向量既是因果必要的也是充分的,并且超越发现提示在本地多轮$ au^2$-Bench轨迹和无动词请求中具有普适性。行为消融实验表明,结构建立了工具调用的先验;转码器分解则揭示分析动词通过信号特征抑制这一先验,表明工具使用并非必要,而执行动词则大致保持其不变。下游结构读取的注意力头和多层感知机特征读取出结果状态,并且相同的机制在来自Qwen、Mistral和Granite家族的七个模型中重复出现。我们的代码可在https://github.com/XijieGo/MI4ToolCalling获取。

Abstract
Complementing the many efforts in providing semantic representations of concepts, notions, and entities in materials science, we report and illustrate a process by which we can automatically build a knowledge graph of the fast evolving field of machine learning applied to the prediction of material properties, focusing on MLIP (Machine Learning Interatomic Potential). This LLM-based process relies on multiple steps, from information extraction in documents and articles to a validation loop using SHACL constraints to detect and correct errors. It is carried out on a model-by-model basis, focusing on the consistency of representation, therefore enabling an iterative construction where the addition of new models is facilitated. We illustrate the process by showing a few interesting aspects that can be queried from a knowledge graph built from the models listed in the Matbench Discovery leaderboard.

MeshSIPP: Efficient Lattice Planning in Dynamic Environment

MeshSIPP:动态环境中的高效格点规划
Agranovskiy, Marat, Yakovlev, Konstantin
Abstract
Autonomous navigation in dynamic environments requires computing spatiotemporal trajectories that satisfy non-holonomic motion constraints. When the trajectories of the moving obstacles are predictable or known, a promising approach is to rely on the combination of state lattices constructed from precomputed feasible motion primitives and Safe Interval Path Planning -- a search-based algorithm with strong theoretical guarantees. While this approach yields feasible paths, the rich primitive sets needed for smooth navigation induce a large branching factor, which becomes costly when coupled with time-dependent obstacle intervals. To this end, we present MeshSIPP, an efficient planner that removes the computational bottleneck by exploiting the fact that many primitives sweep the same regions and can therefore be validated together. MeshSIPP propagates primitives as spatial bundles, screens them with lightweight bounding-interval checks, and defers the expensive exact departure-time search until a primitive reaches its terminal state. A time-aware pruning rule additionally discards redundant space-time branches early in the search. We prove that the resulting search is complete and optimal. Extensive experiments over more than 6,000 benchmark instances and real-time ROS~2 simulations show that MeshSIPP achieves up to a 3$\times$ speedup over state-of-the-art spatiotemporal planners.

在动态环境中进行自主导航需要计算满足非完整运动约束的时空轨迹。当移动障碍物的轨迹是可预测或已知时,一种有前景的方法是依赖于由预计算的可行运动原语构建的状态格点和安全间隔路径规划(Safe Interval Path Planning)——一种具有强理论保证的基于搜索的算法。尽管这种方法能够产生可行路径,但为了实现平滑导航所需的丰富原语集会导致较大的分支因子,当与时间依赖的障碍物区间结合时,计算成本变得昂贵。为此,我们提出了MeshSIPP,一种高效的规划器,通过利用许多原语覆盖相同区域的事实,从而消除了计算瓶颈,因此可以将它们一起验证。MeshSIPP将原语作为空间束传播,通过轻量级的边界间隔检查进行筛选,并将昂贵的精确出发时间搜索延迟到原语达到其终端状态时。一个时间感知的剪枝规则还在搜索早期额外丢弃冗余的时空分支。我们证明了所得到的搜索是完整且最优的。超过6000个基准实例和实时ROS~2模拟的广泛实验表明,MeshSIPP在性能上比最先进的时空规划器快了最多3倍。

Shared and structured inputs undermine collective random choice by reasoning AI agents

共享和结构化输入削弱推理AI代理的集体随机选择
Ezaki, Takahiro, Imura, Naoto, Nishinari, Katsuhiro
Abstract
Random selection is widely used in resource allocation and auditing, making reliable implementation essential for AI-agent systems. Behavioural tests across six reasoning models uncovered threshold and divisibility rules used in identifier-based choices. For threshold-following GPT-6 Sol and Gemini 3.8 Flash, single-agent measurements prospectively predicted correlated participation under shared identifiers and biased participation under distinct identifiers with common timestamp bits. Changing dates, formats and identifier labels revealed when these predictions held. Explicit instructions to randomize independently reduced but did not eliminate shared-input correlation. To test implications for oversight, we asked four models to select customer requests randomly for human review. GPT-6 Sol approached the target rate while selecting predictably from identifiers; the others rarely selected requests. All four closely followed supplied random draws. These findings expose collective and audit vulnerabilities that selection rates alone miss, making input-dependent bias, correlation and predictability central targets for agent evaluation.

Cost-Efficient Theorem Proving via Agent Orchestration in Program Verification

通过代理协调实现程序验证中的成本高效定理证明
Yao, Shuangjie, Holzer, Nikolaus, Santolucito, Mark Paul, Ray, Baishakhi, Jana, Suman, She, Dongdong
Abstract
Program verification establishes software correctness through machine-checkable proofs constructed in theorem provers. It's a guarantee especially valuable for code generated by large language models (LLMs), which is fluent but carries no assurance of correctness. Almost all existing provers, however, pursue pass rates alone at whatever sampling or search budget it takes, and overlook the success-vs-cost frontier; yet real software often carries hundreds of interdependent proof obligations, so what matters at scale is not whether one theorem can be proved, but how many can be proved economically. We introduce CoCo-Prover, which formalizes cost-efficient program proving as metalevel decision-making under cost, grounded on two-level proof graphs: an AND/OR proof hypergraph within each declaration is joined to a lemma-dependency graph across declarations; and at each step, it answers two questions: which open goals to select, and which actions to purchase on these goals. Selection stays symbolic as a topological pass over the proof graphs. Action choice is agent orchestration via metalevel decision-making: an agentic router treats every bounded specialist invocation as a separately priced, best-effort computation, matching heterogeneous specialist agents together with configurations, under evolved routing rules as evidence accumulates. On five program verification benchmarks in Lean 4 including function-level CLEVER, VERINA, and AlgoVeri, and repository-level NTP4VC and Vero, we show that CoCo-Prover achieves a better success-vs-cost frontier than baselines including frontier coding agents and state-of-the-art LLM-based provers: it achieves the best solve rate on every benchmark and up to 100% on two benchmarks. It also reduces cost by up to 30.9% compared to the strongest baseline with the strongest LLM in our evaluation.

程序验证通过在定理证明器中构建可机器检查的证明来确立软件的正确性。这对于由大型语言模型(LLMs)生成的代码尤其重要,尽管这些代码流畅,但并不保证其正确性。然而,几乎所有现有的证明器都仅追求通过率,而不考虑成功与成本之间的平衡;然而,实际软件通常具有数百个相互依赖的证明义务,因此在大规模应用中,重要的不是一个定理是否能被证明,而是能以多经济的方式证明多少个定理。我们引入了CoCo-Prover,它将成本高效的程序证明形式化为在成本下的元层决策,基于两级证明图:每个声明内的AND/OR证明超图与跨声明的引理依赖图相结合;在每一步中,它回答两个问题:选择哪些未完成的目标,以及对这些目标采取哪些行动。选择保持符号化,作为对证明图的拓扑遍历。行动选择是通过元层决策进行的代理协调:一个代理路由器将每个有界的专家调用视为单独定价的最佳努力计算,根据证据的积累,匹配异构专家代理与配置,遵循演变的路由规则。在包括函数级CLEVER、VERINA和AlgoVeri,以及库级NTP4VC和Vero的五个Lean 4程序验证基准测试中,我们展示了CoCo-Prover在成功与成本的平衡方面优于包括前沿编码代理和最先进的基于LLM的证明器的基线:它在每个基准测试中实现了最佳解决率,并在两个基准测试中达到了100%。与我们评估中最强的基线和最强的LLM相比,它还将成本降低了多达30.9%。

System Switch: When Should a Fast Decision Model Stop and Think?

系统切换:快速决策模型何时应停止思考?
Bailo, Gian Luca
Abstract
Dual-process agents pair a fast policy with a slow deliberative model. In real-time settings the slow model usually runs continuously; in turn-based agents and robot planners it is invoked on events such as uncertainty or a detected failure. We study a fast learned actor that takes every decision and hands control to a reasoning vision-language model only when a gate opens, while the game keeps running. We use closed-loop Doom and the new open "System One" typed-decision models, served through a common llama.cpp interface. On 900 held-out questions, (i) zero-shot decision models from 0.15B to 9B parameters choose to collect items 1.6-1.8 times more often than chance among their errors, in any option order, although the order changes some models' accuracy; (ii) accuracy, calibration and sensitivity (how well confidence separates right from wrong answers) are distinct: models of similar accuracy differ widely in AUROC, and the confidence of the most sensitive one tracks which kinds of situation it fails, not which answers are wrong; (iii) offline, deferring the least confident 30% of decisions to a reasoning model gains over random deferral in proportion to the actor's AUROC (rank correlation 0.87); with actor and rate chosen on held-out games the gain is +0.13 [0.08, 0.18] with doomLaya's option order and +0.08 [0.02, 0.14] with shuffled options, and reasoning carries about half of it; (iv) in closed loop (33 games, three seeds) no variant reaches the exit. Committing to plans, the reasoner's or a fixed explore rule's, opens more doors and makes an actor that stands still play; with the rule the agent dies more often. Told that some doors need keys, the reasoner takes ordinary doors for locked ones, which the state cannot tell apart; without that knowledge it goes back to collecting. We release code, prompts, data and logs.

A Tale of Two Error Categories: Exploring Concealed Trade-Offs in the Errors of Automated Judges in Evaluation of Uncertainty Quantifiers

两个错误类别的故事:探索自动评判者在不确定性量化评估中的隐性权衡
Ilia, Evgenia, Aziz, Wilker
Abstract
The wide adoption of LLMs across broad NLG applications heightens the importance of providing users with the means to avert errors and hallucinations. Uncertainty quantification is poised to fill that gap; with low uncertainty (high confidence), as a proxy for correctness, allowing users to be selective (e.g., reject low-confidence, likely incorrect responses). Correlation between confidence and correctness then serves as a useful criterion for evaluation of uncertainty quantifiers (UQs). But in NLG, where diverse responses can be adequate to a prompt, obtaining reliable correctness judgements is not simple, especially without human intervention. Errors in automated judgement are hardly avoidable and known to diminish the reliability of evaluation protocols (Santilli et al., 2025; Ielanskyi et al., 2025). In a meta-analysis of published work, we show that automated judgement is the present norm. Besides, automated judgements are rarely validated against human ones, and the validation of the UQ evaluation they automate is even rarer. With experiments in question answering, using 4 LLMs, human and automated judgements and 7 popular UQs, we find that i) a judge's performance can only coarsely predict the observed impact of its errors on the reliability of UQ evaluation, and that ii) judgement errors tend to misrepresent informative UQs most. We link these observations to patterns of correlation between confidence and categories of judgement error.

大型语言模型(LLMs)在广泛的自然语言生成(NLG)应用中的广泛采用,凸显了为用户提供避免错误和幻觉的手段的重要性。不确定性量化有望填补这一空白;低不确定性(高信心)作为正确性的代理,使用户能够进行选择(例如,拒绝低信心、可能不正确的响应)。信心与正确性之间的相关性因此成为评估不确定性量化器(UQs)的有用标准。然而,在NLG中,由于多样的响应可以满足提示,获得可靠的正确性判断并非易事,尤其是在没有人类干预的情况下。自动判断中的错误几乎是不可避免的,并且已知会降低评估协议的可靠性(Santilli et al., 2025; Ielanskyi et al., 2025)。在对已发表工作的元分析中,我们展示了自动判断是当前的常态。此外,自动判断很少与人类判断进行验证,而它们自动化的不确定性量化评估的验证则更为罕见。通过对4个LLMs、人工和自动判断以及7个流行的不确定性量化器进行的问题回答实验,我们发现:i)评判者的表现只能粗略预测其错误对不确定性量化评估可靠性的影响;ii)判断错误往往最能误导信息丰富的不确定性量化器。我们将这些观察与信心与判断错误类别之间的相关性模式联系起来。

Abstract
Large language models are increasingly contributing to mathematical research, where progress often depends on efficient proof search, incremental improvements and careful verification. We describe Bolzano, a multi-agent open-source system that uses parallel prover agents with a verifier agent and maintains a human-readable research state. Initial manual use on expert-selected problems yielded 8 results whose proofs were checked by domain experts. Motivated by these case studies, we ran Bolzano without problem-specific human guidance on about 3,800 open problems extracted from four sets of papers, solving about 200 open problems. One experiment used papers accepted to STOC 2026, a top conference in theoretical computer science. There, we answered four questions raised in the papers, as confirmed by their authors.

SkillForge: Co-Evolving Skills and Agents via Dynamic Skill Lifecycles

SkillForge:通过动态技能生命周期共同进化技能与智能体
Ge, Yuyao, Wang, Yiwei, He, Yuchen, Bi, Baolong, Mei, Lingrui, Yao, Jiayu, Chen, Lizhe, Liu, Shenghua
Abstract
Memory-augmented reinforcement learning strengthens LLM agents' ability to solve complex long-horizon tasks. Skills are one such form of memory, pairing instructions with an applicability condition over task types. However, retaining every skill indiscriminately as the policy improves lets obsolete or harmful entries accumulate and mislead the agent. We propose SkillForge, an agentic RL method that compiles and evolves the skill library through a fitness-driven skill lifecycle of trial, active, stable, and retired states, so that the skills and the model co-evolve throughout training. A pre-RL evaluation phase first uses the base model's own rollouts to pre-retire low-fitness skills, yielding a filtered library that then seeds supervised fine-tuning. Reinforcement learning takes over from this checkpoint, and at each iteration selective retirement, stabilization, and LLM-guided mutation continue to forge the skill library alongside policy optimization. Across multiple interactive agent benchmarks, SkillForge achieves the highest aggregate success rate, delivering up to 7.8% relative improvement over the strongest baseline while keeping the skill library compact throughout training. We introduce SkillFurnace, a dataset of 5k+ annotated records bundling retirement-filtered SFT trajectories, evolved skill libraries with fitness annotations, and retirement events with human-annotated failure categories to support research on skill quality and lifecycle management.

Self-Evolve With a Reference:Anchored Training of Tool-Integrated Agents

自我进化与参考:工具集成代理的锚定训练
Liao, Wenjie, Zhao, Liangjie, Cao, Zehong
Abstract
Self-evolving tool-integrated agents learn from tasks and feedback generated within their own training loop. A Curriculum Agent generates tasks, while an Executor Agent learns from self-consistency signals through reinforcement learning. However, relying solely on the current Executor for feedback has two limitations: group-relative advantages vanish under full consensus, while uncertainty-based curriculum rewards favor disagreement without showing whether the generated tasks support further learning. These limitations motivate an additional reference beyond the current Executor. We propose \textit{AnchorLoop}, which introduces a frozen copy of the previous iteration's Executor as a historical reference and reuses it on both sides of the training loop. For the Executor, the anchor provides a cross-reference advantage that evaluates current outputs against both current and historical majority answers. For the Curriculum, it provides an agreement-based reference based on differences in sampled majority agreement. Since the Executor and anchor have identical parameters during Curriculum training, this comparison serves as a proxy for task selection rather than evidence of inter-version improvement or correctness. Across 13 reasoning benchmarks, AnchorLoop improves over Agent0 by 2.5\% on mathematical reasoning and 2.8\% on general reasoning tasks. It also maintains higher effective-advantage variance and continues improving in later iterations as the unanchored baseline shows diminishing gains. These results demonstrate the benefit of introducing a lightweight historical reference into self-evolving tool-integrated agents without external task or answer supervision.

LiveMACE: Process-Aware Evaluation of LLM Agent Capabilities in Evolving Markets

Abstract
Evaluating agents by outcomes alone can obscure the capabilities that produce them. This problem is especially pronounced in evolving environments, where outcomes reflect a closed-loop interaction between agent behavior and changing external conditions. We introduce LiveMACEBench, a process-aware benchmark that uses live financial markets as a naturally evolving testbed for persistent LLM agents. Five frontier LLMs operate along continuous trajectories under matched Tool Use, Persistent Memory, Rule Following, and Multi-Agent Collaboration configurations. We evaluate them through both realized outcomes and mechanism-specific diagnostics derived from complete decision traces. Across 30 days of live evaluation, we find a pronounced outcome-capability gap: realized returns often diverge from capability-specific measurements, and similar outcomes can arise from markedly different patterns of mechanism use. Trace-level diagnostics further expose distinct bottlenecks across capabilities, demonstrating that mechanism access, effective mechanism use, and downstream performance are not interchangeable measures of agent capability. LiveMACEBench makes this distinction measurable, turning live markets from a performance leaderboard into a diagnostic environment for agent capability

Think Before You Paint: Recursive Latent Reasoning for Diffusion Models

思考再绘制:扩散模型的递归潜在推理
Skierś, Paweł, Grzanka, Małgorzata, Masarczyk, Wojciech, van de Meent, Jan-Willem, Deja, Kamil
Abstract
Diffusion models generate realistic images but often fail on visual reasoning tasks, such as filling in a Sudoku or drawing the path through a maze. When a discrete symbolic representation is available, recursive methods such as the Tiny Recursive Model (TRM) solve even hard instances of these puzzles. We ask how such reasoning can be carried over to pixels, where no symbolic representation is available. We propose Painter-Thinker (PaTh): a small recursive network (the Thinker) reasons over a grid of learned tokens that encode the noisy image and the conditioning, refines a latent state within every denoising step, and steers a frozen diffusion model (the Painter) through ControlNet adapters. The Thinker is trained with the standard reconstruction loss alone, without symbolic targets, a solver, or a verifier. PaTh solves 92.5% of hard MNIST Sudoku puzzles (prior best 75%) and 71.2% of extreme ones (prior best 4.1%), with 10M parameters against 82M for a standard diffusion model. It also improves on mazes, Queens, and CLEVR scenes with specified spatial relations, and its advantage grows with problem size. Diagnostic experiments show that PaTh recovers from injected mistakes that the diffusion model cannot repair, especially when many cells are wrong. Together, these results show that reasoning mechanisms developed for symbolic data can be integrated into pixel-space diffusion without symbolic supervision, opening a path toward generating data under increasingly complex constraints.

Outperformance Inverse Optimization: Learning Objective Functions that Outperform Agent Decisions

超越表现的逆优化:学习超越代理决策的目标函数
Kitaoka, Akira
Abstract
Inverse optimization estimates the weights of an objective function that explain observed decisions as optimal solutions, and is used in a variety of fields. For mixed-integer linear programs (MILPs), existing methods aim to reproduce the observations as optimal solutions, and thus learn compromise weights when the observations are suboptimal. We propose outperformance inverse optimization, which instead seeks weights that induce, at each state, an optimal solution outperforming the observed action in every component. We give a loss function that can be evaluated with forward-problem oracles alone and is thus applicable to MILPs, together with gradient-based and DC optimization algorithms for minimizing it. For weights inducing a unique outperforming optimal solution at all observations, we prove that the probability of failing to induce such a solution at a new state (the generalization error) is bounded by a quantity inversely proportional to the number of observations, and that this bound is tight in the number of observations up to logarithmic factors. In experiments on synthetic and real data, the proposed methods improve the prediction of solutions outperforming the actions over existing methods.

NL2Hull: A Natural Language-Driven Constrained Ship Design Decision Framework

NL2Hull:一种基于自然语言的受限船舶设计决策框架
Huo, Wenhua, Han, Fenglei, Zhao, Wangyuan, Wu, Jialin, Han, Jiayi
Abstract
Ship-form design combines smooth geometric representation, local shape editing, and constraints on the resulting hull. We present the Natural-Language-to-Hull Framework (NL2Hull Framework), which formulates ship-form editing as a typed discrete decision problem and connects language decisions to numerical geometry. Its Constrained Free-Form Deformation Engine (CFFD Engine) represents hull waterlines with non-uniform rational B-splines (NURBS), applies free-form deformation (FFD) to their control points, reconstructs the hull, and checks geometric constraints. We construct the Ship Design Decision Dataset (SDD Dataset) with 134,558 cleaned records and evaluate compared models on its subset Ship Design Decision Benchmark (SDDBench), containing 5,000 records and 43,496 typed questions. We propose Chip, a constrained ship-design decision model for processing natural-language requests. Chip reaches 95.90\% question accuracy and 99.32\% FFD exact match, with a negative log-likelihood of 0.0951, an expected calibration error of 0.0032, and a Brier score of 0.0551. The NL2Hull Framework provides a reproducible interface for evaluating language-based ship-form decisions while identifying the geometry and continuous-control components that require further development. Our code and dataset is available at https://github.com/wenhuahuo/NL2Hull.

Where Can a Decision Model Diagnose HVAC Faults? Reasoning Demand, Physical Representation, and Robustness Under Shift

决策模型如何诊断HVAC故障?推理需求、物理表征与条件变化下的鲁棒性
Jung, Wooyoung
Abstract
Artificial intelligence supports building operations in several forms, each with its own barrier. Expert rules must be tuned for every system, supervised models need labeled data that buildings rarely record, and language models return free text that requires human-in-the-loop checking, since their stated confidence is unreliable. A newer kind of pretrained model, here called a decision model, returns a probability for every allowed answer, so one model could serve many decisions without training. This study answers three open questions for fault diagnosis in heating, ventilation, and air-conditioning systems: which decisions such a model can make, what input it needs, and whether its probabilities hold when conditions change. On 128 fault days from four public datasets of real equipment, faults are graded by the reasoning their diagnosis demands, with data given raw, as physical features, or with Brick topology. The decision model Jev, open language models, and a supervised model face nine tests that change season, control configuration, or building. Given physical features, Jev and the larger open model diagnosed faults whose evidence one feature carries, but not faults that need operating context. Under shift they kept their accuracy and calibration, while the supervised model lost 0.33 macro-F1 yet led or tied within a building. Their probabilities still needed correction, and detection was weak. The study maps which faults a decision model can diagnose and from what input, and supports a division of work in which code computes the physics and the model ranks candidate faults for an operator.

AgentTime: Can Agents Estimate and Control Their Own Runtime?

AgentTime:智能体能否估计和控制自己的运行时间?
Ofengenden, Michael, Andriushchenko, Maksym
Abstract
An essential control of AI agents is their ability to manage runtime. This ability requires a sense of time-awareness, to predict and estimate wall-clock time and to control their own actions. Prior work has focused on time-awareness, but duration-following and control in native agent harnesses remain unexplored. We present AgentTime, a benchmark for testing whether agents can work for a requested duration, predict their runtime, and estimate elapsed time afterward. It comprises 222 tasks from 18 sources spanning coding, computer use, agentic work, and automated research. Duration-following experiments append a single instruction specifying how long to work, with requests ranging from about a minute to multiple days. Accuracy on these instructions varies substantially: Fable 5.1 in Claude Code deviates from requested runtimes by a typical factor of 2.9$\times$, compared with only 1.2$\times$ for GPT-6 Astra in Codex. However, matching the requested runtime does not, by itself, establish continued work on the task. Among 158 reviewed Astra runs with classifiable transcripts, 14 explicitly slept after appearing to finish. In forecasting experiments, predictions tend to overestimate natural runtimes. In retrospective experiments, removing temporal information more than doubles deviation for Sol and Astra and nearly doubles it for Fable. An agent's ability to complete a task does not guarantee that it can control its own time or work for the whole requested duration. For agents to run reliably, safely, and autonomously over long horizons, we require the evaluation of both.

AI智能体的一个重要控制能力是管理运行时间。这一能力需要具备时间意识,以预测和估计实际时间,并控制其自身的行为。之前的研究集中于时间意识,但在原生智能体的持续时间跟随和控制方面仍然未被探索。我们提出了AgentTime,这是一个用于测试智能体是否能够在请求的持续时间内工作、预测其运行时间并在之后估计经过时间的基准。该基准包含来自18个来源的222个任务,涵盖编码、计算机使用、智能体工作和自动化研究。持续时间跟随实验附加了一条指令,指定工作多长时间,请求的持续时间范围从大约一分钟到多天不等。这些指令的准确性差异显著:Claude Code中的Fable 5.1与请求的运行时间偏差的典型因子为2.9×,而Codex中的GPT-6 Astra仅为1.2×。然而,仅仅匹配请求的运行时间并不能证明智能体能够持续进行任务。在158个可分类转录的Astra运行中,有14个在看似完成后明确进入睡眠状态。在预测实验中,预测往往高估自然运行时间。在回顾性实验中,移除时间信息使得Sol和Astra的偏差增加了两倍以上,而Fable的偏差几乎增加了两倍。智能体完成任务的能力并不保证其能够控制自己的时间或在整个请求的持续时间内工作。为了使智能体在长时间范围内可靠、安全和自主地运行,我们需要对这两者进行评估。

Successive Training Stages and Large Language Model Persuasion: Effects of Misalignment, Supervised Fine-Tuning, and Preference Optimization

连续训练阶段与大型语言模型的说服力:不一致性、监督微调和偏好优化的影响
Dalmiere, Antony, Marchand, Pascal, Auriol, Guillaume, Nicomette, Vincent
Abstract
Large language models (LLMs) can be tuned to influence human attitudes, yet the respective contributions of successive post-training stages remain un-clear. This study examines how three successive training stages affect LLM persuasiveness: (1) misalignment through supervised fine-tuning (SFT) on conspiracy data, (2) additional persuasive SFT on argumentative data, and (3) Identity Preference Optimization (IPO), a preference-optimization method. A total of 835 participants recruited on Prolific were randomly assigned to five between-subject conditions (neutral text, conspiracy-trained model, persuasion-trained model, preference-optimized model, and GPT-4) and were exposed to texts on 10 divisive political issues, personalized from their individual profiles in all model conditions. Attitude change was measured as the difference between pre- and post-exposure positions on continuous Likert scales and analyzed with an analysis of covariance (ANCOVA). A significant condition x baseline-attitude interaction, F (4, 825) = 5.33, p < .001, indicated that training effects depended on participants' initial attitudes. Persuasive SFT produced greater attitude change than conspiracy training alone, d = 0.30, whereas IPO provided no additional benefit, d = 0.03, and GPT-4 did not differ from neutral text, d = --0.01. These results show that targeted supervised training on persuasive data increases LLM persuasiveness, whereas preference optimization yields no significant gains beyond it.

大型语言模型(LLMs)可以被调优以影响人类态度,但各个后训练阶段的具体贡献仍不明确。本研究考察了三个连续训练阶段如何影响LLM的说服力:(1)通过对阴谋数据进行监督微调(SFT)而产生的不一致性,(2)在论证数据上进行额外的说服性SFT,以及(3)身份偏好优化(IPO),一种偏好优化方法。共招募了835名参与者,他们在Prolific平台上被随机分配到五个被试条件(中性文本、阴谋训练模型、说服训练模型、偏好优化模型和GPT-4),并接触到关于10个具有争议的政治问题的文本,这些文本根据参与者的个人资料进行了个性化处理。在所有模型条件下,态度变化通过在连续的李克特量表上测量接触前后态度的差异来评估,并通过协方差分析(ANCOVA)进行分析。显著的条件与基线态度交互作用,F (4, 825) = 5.33, p < .001,表明训练效果依赖于参与者的初始态度。说服性SFT产生的态度变化大于仅进行阴谋训练的效果,d = 0.30,而IPO未提供额外益处,d = 0.03,且GPT-4与中性文本没有显著差异,d = -0.01。这些结果表明,针对说服性数据的有针对性的监督训练能够提高LLM的说服力,而偏好优化未能在此基础上带来显著提升。

From Expected Harmfulness to Likelihood: A Probabilistic Reformulation of Jailbreaking LLM Agents

从预期有害性到可能性:对监狱破解大型语言模型代理的概率重构
Xu, Juanyang, Wang, Zheng, Zhao, Xingyu, Khastgir, Siddartha, Zhang, Andi
Abstract
When the harmfulness of an LLM agent's output can be quantified, a natural jailbreaking objective is to maximize expected harmfulness over admissible input modifications. An alternative approach constructs or selects harmful target outputs and modifies the input to increase their likelihood. We establish a precise connection between these two approaches through a probabilistic reformulation. Specifically, we show that the gradient of the logarithm of expected harmfulness with respect to the input equals the expected input gradient of the model's log-likelihood under a harmfulness reweighted output distribution. This identity provides a unified interpretation of expected harmfulness and target likelihood optimization. Building on this connection, we propose OPUR, a sampling distribution designed to generate highly harmful target outputs and use the resulting samples to guide likelihood-based input optimization. Experiments demonstrate the effectiveness of the resulting method in jailbreaking LLM agents.

What the Sleeve Feels: Explainable Machine Learning for Textile Pressure-Based Postural Screening

袖子所感知的:基于压力的纺织品姿势筛查的可解释机器学习
Hossain, Limon Bin, Ananta, Md Sadib Rahman
Abstract
Pressure-sensing smart textiles convert body-surface contact into a dense, image-like signal closely tied to posture and movement, making them a promising low-cost route to wearable posture screening. Realizing that promise, however, requires more than classification accuracy: a deployable system must generalize to wearers unseen during training, expose the physical evidence behind its decisions, and tolerate the small donning offsets that occur whenever a garment is removed and re-worn. This paper addresses these three requirements jointly using a knitted piezoresistive sleeve worn on the forearm as a testbed. We regroup fine-grained everyday activities into three coarser screening categories (neutral, potentially undesirable, and functional or transitional), engineer 29 interpretable pressure-distribution features spanning global intensity, spatial center of pressure, quadrant asymmetry, distribution complexity, and short-horizon temporal change, and evaluate under a strict subject-wise split. A tuned XGBoost classifier reaches 0.818 accuracy, 0.788 balanced accuracy, and 0.801 macro F1 on unseen test subjects, with tight frame-level bootstrap 95% intervals of about plus-minus 0.01 and a subject-to-subject standard deviation near 0.06 under leave-one-subject-out cross-validation. A simple 2D-CNN baseline trained on raw frames achieves broadly similar performance, showing that hand-engineered features are not left behind by a learned spatial representation on this task. SHAP-based explanation, a feature-group ablation, per-activity error analysis inside the pooled undesirable class, class-mapping sensitivity, and a simulated donning-rotation stress test together locate what the model relies on, where it degrades, and why, directly targeting the generalization, interpretability, and robustness gaps that determine whether such a system is deployable.

压力感应智能纺织品将身体表面的接触转化为与姿势和运动紧密相关的密集图像信号,使其成为一种有前景的低成本可穿戴姿势筛查方案。然而,实现这一承诺不仅需要分类准确性:一个可部署的系统必须能够推广到训练过程中未见过的佩戴者,揭示其决策背后的物理证据,并容忍每当衣物被脱下再穿时发生的小偏差。本文使用一种佩戴在前臂的针织压阻袖子作为测试平台,联合解决这三个要求。我们将细粒度的日常活动重新分组为三种较粗的筛查类别(中性、潜在不良和功能性或过渡性),设计了29个可解释的压力分布特征,涵盖了全局强度、压力中心的空间位置、象限不对称性、分布复杂性和短期时间变化,并在严格的受试者分割下进行评估。经过调优的XGBoost分类器在未见测试受试者上达到了0.818的准确率、0.788的平衡准确率和0.801的宏观F1分数,且在留一受试者交叉验证下,帧级自助法95%置信区间约为±0.01,受试者间标准差接近0.06。一个简单的2D-CNN基线在原始帧上训练,达到了大致相似的性能,显示出在此任务中手工设计的特征并未被学习的空间表示所超越。基于SHAP的解释、特征组消融、在汇总不良类别内的逐活动错误分析、类别映射敏感性以及模拟的穿戴-旋转压力测试共同定位了模型所依赖的因素、其退化的地方及原因,直接针对决定该系统是否可部署的泛化性、可解释性和鲁棒性差距。

Learning to Accumulate Knowledge with Mutual Information

通过互信息学习知识积累
Zhao, Yuyang, Liao, Lizi, Shen, Leyang, Zhao, Xiaoyan, Zhang, Yang, Feng, Fuli, He, Xiangnan
Abstract
Large language model (LLM) agents can improve their performance by reusing knowledge distilled from past interactions. However, curating new experiences into a knowledge bank that becomes more useful as it grows remains challenging. Effective knowledge accumulation should limit redundant overlap among entries and ensure that new knowledge contributes beyond what the bank already provides. Yet training a curator with Group Relative Policy Optimization (GRPO) on standalone task success can reinforce general guidance even when it duplicates existing knowledge. Therefore, we propose Knowledge Weaver, a reinforcement learning framework that trains a language model to curate reusable knowledge from agent trajectories. We couple feedback inspired by token-wise mutual information (MI) with marginal success rewards to guide knowledge accumulation. Together, these signals encourage the curator to preserve distinct information from experience and produce entries that improve task success when added to existing knowledge. Standalone success rewards also favor entries that are useful on their own. On ALFWorld and WebShop, Knowledge Weaver achieves mean success rates of 54.0\% and 42.0\% with k=10 retrieved entries, exceeding GRPO by 16.9 and 18.7 percentage points, respectively. Its knowledge banks also outperform the evaluated prompt-based and established banks, including human-written banks, in overall ALFWorld success rate and WebShop score with the executor frozen.

大型语言模型(LLM)代理可以通过重用从过去交互中提炼的知识来提高其性能。然而,将新的经验整理成一个知识库,使其在增长时变得更加有用,仍然是一个挑战。有效的知识积累应限制条目之间的冗余重叠,并确保新知识在现有知识库的基础上做出贡献。然而,使用群体相对策略优化(Group Relative Policy Optimization, GRPO)对独立任务成功进行训练时,即使重复现有知识,也可能强化一般指导。因此,我们提出了知识编织者(Knowledge Weaver),一个强化学习框架,旨在训练语言模型从代理轨迹中整理可重用的知识。我们将受启发于逐词互信息(mutual information, MI)的反馈与边际成功奖励相结合,以指导知识积累。这些信号共同鼓励策展人保留经验中的独特信息,并生成在添加到现有知识时能够提高任务成功率的条目。独立成功奖励也有利于那些本身有用的条目。在ALFWorld和WebShop上,知识编织者在检索到k=10个条目时,分别达到了54.0\%和42.0\%的平均成功率,分别超越GRPO 16.9和18.7个百分点。其知识库在整体ALFWorld成功率和WebShop评分方面也优于评估的基于提示的和已建立的知识库,包括人类编写的知识库,且执行器保持不变。我们的代码库可在https://github.com/LaoKuiZe/Knowledge-Weaver获取。

Loud Failures, Quiet Failures: Fault Detection and Recovery in Tool-Using Language Model Agents

响亮的失败与安静的失败:工具使用语言模型代理的故障检测与恢复
Kraishan, Obada
Abstract
Tool-using agents are usually scored on whether they finish a task while the tools work. Deployments are less forgiving: services time out, endpoints disappear, parameter names change, and results come back well formed but wrong. Prior work has shown that language models over-trust tool outputs that fail silently; we ask how that over-trust plays out across the stages of failure handling in multi-turn agents. Wrapping the executable environments of an established function-calling benchmark in a fault-injection layer, we inject one of four typed faults at a controlled point in the trajectory and record whether the agent notices, changes plan, recovers the task, or repeats itself. Six models from three families, half of them reasoning variants, ran 1,920 trials over 24 multi-step tasks. Agents treat a failure as a problem in 91.3% of trials when the tool returns an explicit error, but in 58.8% of trials when it returns a plausible wrong value, against a 26.8% rate of reporting problems when nothing was wrong. Reasoning models are not better placed: paired against instruct siblings, they notice less (-9.3 points, p < .001) and change plan more (+10.4 points, p < .001), and recovery is unchanged (p = .512). Because agents are stochastic, two fault-free runs of the same task end in the same state only 63.3% of the time; against that baseline, only a missing tool clearly lowers recovery (39.9%), while timeouts, schema drift, and corruption stay within run-to-run variation. After a fault, agents return to the same tool three or more times in a row in up to 22.2% of trials, though strictly identical repeats are rare. A prompt line asking the agent to check each result did not move detection. Agents respond to the error channel rather than to the content of what a tool returns, so failures that stay inside the expected format pass through.

工具使用代理通常根据它们在工具正常工作的情况下是否完成任务来评分。然而,实际部署的环境则不那么宽容:服务超时、端点消失、参数名称变化,结果虽然格式正确但却是错误的。先前的研究表明,语言模型对静默失败的工具输出过于信任;我们探讨这种过度信任在多轮代理的故障处理阶段是如何表现的。通过在一个已建立的函数调用基准的可执行环境中包裹一个故障注入层,我们在轨迹的受控点注入四种类型的故障之一,并记录代理是否注意到、改变计划、恢复任务或重复自己。来自三个家族的六个模型,其中一半是推理变体,在24个多步骤任务中进行了1920次试验。当工具返回明确错误时,代理在91.3%的试验中将故障视为问题,而当工具返回一个看似合理的错误值时,这一比例降至58.8%,而在没有任何问题时,仅有26.8%的情况下报告问题。推理模型的表现并没有更好:与指令兄弟模型相比,它们的注意力更少(-9.3个百分点,p < .001),而改变计划的频率更高(+10.4个百分点,p < .001),恢复能力没有变化(p = .512)。由于代理是随机的,同一任务的两个无故障运行仅在63.3%的情况下结束于相同状态;与此基线相比,只有缺失工具明显降低了恢复率(39.9%),而超时、模式漂移和数据损坏则保持在运行间的变异范围内。在发生故障后,代理在最多22.2%的试验中连续返回到同一工具三次或更多次,尽管严格相同的重复情况较为罕见。要求代理检查每个结果的提示行并未提高故障检测率。代理更倾向于响应错误通道,而不是工具返回内容,因此保持在预期格式内的故障得以通过。

HGP:An on-device personalized agent memory via hybrid graph storage

HGP:一种通过混合图存储实现的设备内个性化代理记忆
Zhou, Ran, Han, Xueming, Liu, Jiaheng, Zhang, Yuyao, Meng, Fanyu, Feng, Junlan, Ren, Yuxiang
Abstract
LLM-based agents face challenges in personalized interactive tasks due to heterogeneous, multi-typed, and implicitly constrained long-term traces. Existing memory mechanisms struggle with accurate routing and retrieval, especially on-device where personalization is critical. Most methods use single-vector representations, blurring type distinctions and relational structure. We propose HGP, a hybrid graph memory framework. HGP employs a lightweight self-enhancement classifier for personalized memory routing and constructs episodic, semantic, and procedural memories as graphs. It also extracts working memory as a state trajectory to capture current state and implicit constraints, ensuring reliable decision-making. The classifier reduces large-model calls, enabling on-device deployment, while graph storage enables accurate retrieval and incremental user profile refinement. Experiments on two benchmarks show that on PAL-Set solution selection, HGP achieves an S-score of 35.58, nearly 7 points above the strongest baseline.

SkillSandbox: Skill Verification via Dynamic Scenario Synthesis

技能沙盒:通过动态场景合成进行技能验证
Kim, Serin, Seo, Kwangwook, Song, Dokyung, Yeo, Jinyoung, Lee, Dongha
Abstract
Self-evolving agents distill task-solving experience into skills for future reuse, but these skills can encode incorrect procedures or non-transferable knowledge. It is therefore critical to verify each skill's reusability: whether its guidance remains useful beyond the experience from which it was distilled. Such verification requires observing how a skill affects execution in new tasks, yet existing tasks may not expose the situations where the target skill can actually be exercised. To construct such situations, we propose SkillSandbox, a framework that dynamically synthesizes a task and its environment for each skill that are skill-relevant yet novel. A Proposer specifies the conditions to preserve and the source-specific details to vary, a Builder constructs an executable scenario, and a Verifier compares executions with and without the skill. The Verifier assesses executability, utility, and efficiency to assign a Keep or Reject verdict, determining whether the skill enters the library. Across ALFWorld and WebShop with three models, SkillSandbox consistently yields the strongest downstream performance and improved execution efficiency. Further analyses examine whether these gains reflect accurate assessment of skill reusability and identify which components of SkillSandbox contribute to them.

RewardWeaver: Long-Horizon Interactive Learning for Language Agents via Self-Evolving Reward Adaptation

RewardWeaver:通过自我演化奖励适应实现语言代理的长时间交互学习
Xiao, Hengbo, Zhang, Boyao, Liu, Purui, Zheng, Yuxuan, Yin, Haoran, Liu, Haibo, Zhang, Fan
Abstract
Reinforcement learning with verifiable rewards (RLVR) has driven substantial progress in domains where task outcomes can be reliably evaluated, but long-horizon interaction remains challenging due to sparse terminal feedback and difficult credit assignment. Process rewards provide denser supervision, yet the capabilities most relevant for training can change as the policy evolves: a behavior that is easy to evaluate or frequently deficient need not be the bottleneck currently limiting task success. We introduce RewardWeaver, a self-evolving reward adaptation framework for language agents in long-horizon interaction. RewardWeaver maintains a validated capability space in which the semantics of admitted Rubrics remain fixed, and closes the loop between policy optimization, task evaluation, failure attribution, and reward adaptation. After each training stage, it performs outcome-grounded backward attribution on low-outcome trajectories, aggregates recurrent and policy-controlled capability bottlenecks, and dynamically selects the corresponding process rewards for the next stage. Recurrent failures not covered by the existing capability space trigger a separate, controlled expansion procedure. We evaluate REWARDWEAVER on SOTOPIA, Amazon?HistoryPrice, and a newly constructed Sales Benchmark. Across social interaction, bilateral bargaining, and domain-specific sales, REWARDWEAVER establishes new state-of-the-art (SOTA) results. Ablations further demonstrate the importance of dynamic reward allocation, failure-grounded attribution, and stable semantics for admitted capabilities.

UniSkill: Learning Actor-Aligned Skill Proposals for an Evolving Policy

UniSkill:学习与行为者对齐的技能提案以适应不断演变的策略
Lu, Yifei, Liu, Cheng, Yu, Dianzhi, Xiang, Hui, Zhang, Ji, Xiao, Yuanchu, Liang, Rong
Abstract
Large language model agents can improve across tasks by retaining reusable skills distilled from prior interactions. Recent work jointly optimizes task execution and skill extraction, enabling the policy and skillbank to co-evolve. However, as the actor continues learning, rewarding skill proposals through their reuse in subsequent training steps may conflate skill benefits with actor improvement, while directly testing each proposed skill requires costly additional actor rollouts. In this paper, we introduce UniSkill, which uses a shared policy to interact with the environment and propose skillbank edits (Add, Update, or No Edit) from the resulting trajectories. Specifically, the actor learns from environment rewards, while contrastive action feedback guides skill proposal learning. This feedback provides an actor-alignment signal by measuring how replacing the retrieved skill with a proposed skill changes the current actor's action log-likelihood gap between previously collected successful and failed trajectories from the same task, thereby avoiding new rollouts for each proposal. Since proposal-level feedback may suppress an otherwise appropriate edit operation when the proposed skill content scores poorly, we further apply skill-edit support regularization to preserve exploration. Empirically, UniSkill achieves strong performance, reaching 98.4% success on ALFWorld and 84.7% on WebShop while maintaining stable joint training. Further ALFWorld experiments show that UniSkill remains effective when the shared policy uses a smaller backbone. Our implementation is available at https://github.com/LimOkii/UniSKill.

大型语言模型代理可以通过保留从先前交互中提炼的可重用技能来在任务中不断提升。近期的研究联合优化任务执行和技能提取,使得策略和技能库能够共同演化。然而,随着行为者的持续学习,通过在后续训练步骤中重用技能提案来奖励这些技能可能会将技能的好处与行为者的改进混淆,而直接测试每个提议的技能则需要额外的高成本行为者回合。在本文中,我们介绍了UniSkill,它使用共享策略与环境交互,并根据生成的轨迹提出技能库编辑(添加、更新或不编辑)。具体而言,行为者从环境奖励中学习,而对比动作反馈则指导技能提案学习。这种反馈通过测量用提议技能替换检索到的技能如何改变当前行为者在同一任务中先前收集的成功和失败轨迹之间的动作对数似然差距,提供了一个与行为者对齐的信号,从而避免了对每个提案进行新的回合。由于提案级反馈可能会抑制在提议技能内容评分较低时的适当编辑操作,我们进一步应用技能编辑支持正则化以保持探索。从经验上看,UniSkill在ALFWorld上取得了98.4%的成功率,在WebShop上达到了84.7%的成功率,同时保持了稳定的联合训练。进一步的ALFWorld实验表明,当共享策略使用较小的主干时,UniSkill仍然有效。我们的实现可在https://github.com/LimOkii/UniSKill获取。

Agentic AI-Assisted Modeling for Production Scheduling: Assessment in Constraint Programming

基于代理的人工智能辅助生产调度建模:约束编程中的评估
Sánchez-Fernández, Ángel, Pernas-Álvarez, Javier, Crespo-Pereira, Diego
Abstract
Developing optimization models for production scheduling requires substantial expert effort. Research on large language models (LLMs) has followed two directions: specialized approaches for automated modeling, mostly for mixed-integer linear programming, which often rely on dedicated training or problem-specific architectures that limit industrial deployment; and agentic artificial intelligence for operational decision support, which generally assumes that the optimization model already exists. This study bridges both directions by assessing whether general-purpose LLMs, orchestrated as agents without task-specific training, can formulate and implement constraint programming models from natural-language problem descriptions. Singleagent and multi-agent architectures are integrated with a Model Context Protocol server that provides context-aware retrieval of solver documentation to mitigate hallucinations during implementation. Both are compared with a direct LLM baseline on six industry-oriented problems covering flow-shop, job-shop, flexible job-shop and resource-constrained warehouse scheduling, using three LLMs and assessing modeling accuracy, execution success, latency and token consumption. Formulation proves largely within reach of current LLMs, whereas implementation is the main barrier. The multi-agent workflow raises the share of scripts that run correctly as generated from 14.8% with a direct LLM call to 59.3%, reaching 80.6% on the four less complex problems, while tightly coupled intralogistics models remain an open challenge.

开发生产调度的优化模型需要大量的专家努力。关于大型语言模型(LLMs)的研究主要有两个方向:一种是针对自动建模的专业方法,主要用于混合整数线性规划,这通常依赖于专门的训练或特定问题的架构,限制了其在工业中的应用;另一种是用于操作决策支持的代理人工智能,通常假设优化模型已经存在。本研究通过评估通用LLMs在没有任务特定训练的情况下,能否从自然语言问题描述中制定和实施约束编程模型,来桥接这两个方向。单代理和多代理架构与模型上下文协议(Model Context Protocol)服务器集成,该服务器提供上下文感知的求解文档检索,以减少实施过程中的幻觉。我们将这两种方法与直接LLM基线进行比较,涵盖六个面向工业的问题,包括流动车间、作业车间、灵活作业车间和资源约束仓库调度,使用三种LLM并评估建模准确性、执行成功率、延迟和令牌消耗。结果表明,建模在当前LLMs的能力范围内,而实施是主要障碍。多代理工作流程将直接LLM调用生成的正确运行脚本比例从14.8%提高到59.3%,在四个较简单的问题上达到80.6%,而紧密耦合的内部物流模型仍然是一个未解决的挑战。

GAGR-Lab: Evaluating Joint Spatial-Geometric and Analytic Function Reasoning

GAGR-Lab:评估联合空间-几何与分析函数推理
Zhang, Jingyao, Li, Yun, Han, Lu
Abstract
Joint spatial-geometric and analytic function reasoning requires translating a perceived spatial configuration into a symbolic function whose executed curve satisfies geometric constraints. We present GAGR-Lab, a framework for measuring this capability through Cartesian game scenes, explicit function semantics, and authoritative Rust trajectory execution. It distinguishes spatial perception, metric grounding, geometric relations, function interpretation, function construction, and constrained synthesis. We specify four configurable scene-difficulty presets and a prospective 24-cell diagnostic design, while reporting only the subset actually evaluated. A bounded pilot of one hosted model (Llama 3.2 11B Vision Instruct) using two API credentials as execution replicas yields 72 balanced games with 432 attempts, 429 valid provider responses, and no target hits; exploratory ordinary-function prompt variants also fail to hit, while the structured localization interface yields no scoreable outputs. A privileged analytic search control independently succeeds on 600 directional cases from 300 generated scenes, with exact repeatability and 1,200 successful vertical-reflection or translation checks. The framework separates serving reliability, symbolic compliance, and geometric success, and preserves exact model-visible inputs and realized paths. A staged protocol outlines diagnostic calibration, held-out replication, multi-model comparison, and paired robustness tests. The contribution is an operational research framework with an executed pilot and a clearly identified prospective study plan; the full difficulty matrix and comparative model results remain untested.

OOM-RL II: Reality Is an Oracle, Not a Debugger Provenance-Constrained Diagnosis in Continually Evolving Agent-Engineered Systems

OOM-RL II: 现实是一个预言者,而不是调试器——在持续演变的代理工程系统中的来源约束诊断
Liu, Kun, Chen, Liqun
Abstract
Reality may establish that an outcome occurred without identifying which evolving procedure produced it or why. This distinction matters in production ML systems whose code, configuration, and artifacts change while external feedback accumulates. We examine it in a human-directed, agent-engineered quantitative trading system, using oracle to mean an external source of realized outcomes rather than a complete correctness specification. Across one year, the account gained and outperformed a broad market index, while annual alpha was not statistically distinguishable from zero under the main retrospective specification. Retrospectively selected subperiods include adverse relative performance and conditional candidate-level weakness under declared approximate references. Engineering records document changes during the episode, and complete recommendation-to-runtime binding is unavailable. The archive does not establish a common frozen instance or a unique cause. The case motivates an outcome--diagnosis gap: outcome evidence, evaluated-object identity, and causal explanation support distinct claims. We distinguish frozen instances, pre-specified adaptive procedures, and ad-hoc development; organize archive-relative claim identifiability and an evidence hierarchy; and propose a prospective production-binding protocol. An illustrative compatible-history example shows how factual binding can resolve a recommendation's referent without supplying its counterfactual effect. The protocol is proposed rather than prospectively validated. External feedback constrains outcome claims, while provenance and additional identification structure determine the resolution of diagnosis.

Stale, Misattributed, or Late: Where Personal Memory Fails Before Generation

过时、错误归属或延迟:个人记忆在生成之前的失效
Deng, Haonan, Sinchaisri, Park
Abstract
Personal memory for language agents is usually judged by whether the final an- swer is correct. That score hides errors that arise before generation: the memory block may contain an obsolete value, a fact about the wrong person, or no use- ful fact before the serving deadline. We measure these failures directly. Using Personal Fact Memory (PFM) as a reference layer, we find that temporal validity is primarily a property of memory construction in our setting. On a controlled revision benchmark, serving only the active value of each correctly keyed slot eliminates observed stale exposure; without update resolution, 70.3% of prompts expose a superseded value. Once retrievers share the same active store and par- ticipant information, participant-aware BM25 is equivalent to the reference ranker within a prespecified 0.02 margin. The harder problem is assigning revisions to the right slot. Missed merges leave stale values active, whereas false merges silently remove current values; four LLM key assigners achieve higher key re- call than a rule extractor yet produce lower clean-retrieval rates, and open-domain merge recall on LongMemEval never exceeds 0.062. Misattribution survives va- lidity filtering: an entity posterior reduces same-name exposure on controlled data but cannot distinguish identically named speakers in LoCoMo. Two frozen lan- guage models reproduce prompt errors in generated text. Retrieval latency varies across rankers, but prompt prefill dominates turn-level latency on our hardware. These results argue for evaluating agent memory before generation, separating stored-state validity, identity resolution, abstention, and serving latency.

语言代理的个人记忆通常通过最终答案的正确性来评判。然而,这种评分掩盖了在生成之前出现的错误:记忆块可能包含过时的值、关于错误人物的事实,或在服务截止日期之前没有有用的事实。我们直接测量这些失效。以个人事实记忆(Personal Fact Memory, PFM)作为参考层,我们发现时间有效性主要是我们设置中记忆构建的一个属性。在一个受控的修订基准上,仅提供每个正确键槽的活动值消除了观察到的过时曝光;在没有更新解析的情况下,70.3%的提示暴露了被替代的值。一旦检索器共享相同的活动存储和参与者信息,参与者感知的BM25在预设的0.02误差范围内等同于参考排名器。更棘手的问题是将修订分配到正确的槽位。遗漏的合并使过时值保持活动状态,而错误的合并则默默移除当前值;四个LLM键分配器的键召回率高于规则提取器,但产生的干净检索率较低,而在LongMemEval上的开放域合并召回率从未超过0.062。错误归属在有效性过滤中仍然存在:实体后验在受控数据上减少了同名曝光,但无法区分LoCoMo中同名发言者。两个冻结的语言模型在生成文本中重现了提示错误。检索延迟在不同排名器之间有所不同,但提示预填充在我们的硬件上主导了回合级延迟。这些结果支持在生成之前评估代理记忆,区分存储状态有效性、身份解析、弃权和服务延迟。

AI Safety Considerations for Agents With Limited Time to Act

有限行动时间下智能体的安全性考虑
Zeitler, Leo, Richings, Jack, Nockles, Victoria
Abstract
In the wake of the increasingly public discussion about AI alignment, recent work has tried to propose specific AI architectures that behave safely. However, the proposed arguments that seemingly demonstrate proved alignment mostly neglect the environment the agent needs to act in. We discuss theoretical bounds for agent-agnostic safety guarantees in environments that can only be partially observed and within which an action is required within limited time. We introduce two realistic scenarios, one with an infinite state space and one with signal mixture. In these scenarios, we prove that even a perfect agent cannot guarantee safe behaviour. It will be argued that for any proof of AI safety or alignment, the environment and associated safe actions need to be specifically considered together with the agent.

The Handover Problem: Governing Autonomy Transitions in Human-AI Collaboration

交接问题:人机协作中的自主性转变管理
Pelechano, Vicente, Mestre, Antoni, Albert, Manoli, Gil, Miriam
Abstract
Human-machine systems rarely operate at a fixed level of AI autonomy. As operators and AI systems collaborate over time, control must shift: the AI can take on more responsibility when collaboration is stable, maintain its current role when evidence is ambiguous, or return control to the human when conditions deteriorate. Existing work on adaptive automation, supervisory control, trust in automation, and deskilling explains parts of this problem, but provides no auditable, multi-signal criterion for governing when autonomy should change across multi-cycle workflows. We formalise this challenge as the Handover Problem: deciding, at each operational cycle, whether to escalate, maintain, or revert AI autonomy while keeping the process reversible, recoverable, and auditable. We introduce the Handover Readiness Score (HRS), a transparent composite measure that integrates four signal dimensions: operator readiness, human-AI trust, learning stability, and operational performance. It is combined with a hysteresis-based transition policy that requires sustained positive evidence before increasing autonomy but reverts promptly when conditions worsen. Across software engineering and manufacturing domains, the HRS and hard safety guards address complementary failure regimes: guards enforce immediate corrective action when a single indicator breaches a critical threshold, while the HRS detects the slow, multi-signal erosion of operator readiness that no individual guard can observe. The framework establishes autonomy handover as a governance problem requiring explicit, composite, and auditable criteria. This provides a conceptual and formal foundation that adaptive automation research has not previously provided.

人机系统很少在固定的人工智能(AI)自主性水平下运行。随着操作员与AI系统的长期协作,控制权必须发生转移:当协作稳定时,AI可以承担更多责任;当证据模糊时,保持当前角色;而在条件恶化时,将控制权返回给人类。现有关于自适应自动化、监督控制、对自动化的信任和技能退化的研究解释了这一问题的部分内容,但未提供可审计的、多信号标准来管理在多周期工作流程中自主性何时应发生变化。我们将这一挑战形式化为交接问题:在每个操作周期内,决定是升级、维持还是恢复AI自主性,同时保持过程的可逆性、可恢复性和可审计性。我们引入了交接准备评分(Handover Readiness Score, HRS),这是一种透明的综合测量,整合了四个信号维度:操作员准备情况、人机信任、学习稳定性和操作性能。它与基于滞后效应的转变政策相结合,该政策要求在提高自主性之前必须有持续的正面证据,但在条件恶化时会迅速恢复。针对软件工程和制造领域,HRS和严格的安全防护措施解决了互补的故障模式:当单一指标突破临界阈值时,防护措施强制立即采取纠正行动,而HRS则检测操作员准备情况的缓慢、多信号退化,这是任何单一防护措施无法观察到的。该框架将自主性交接确立为一个治理问题,要求明确、综合和可审计的标准。这为自适应自动化研究提供了之前未曾提供的概念和形式基础。

Open-MMUnlearning: Unifying Methods and Evaluation for MLLM Unlearning

Open-MMUnlearning:统一多模态大语言模型(MLLM)去学习的方法与评估

Abstract
As multimodal large language models (MLLMs) become more capable and widely deployed, concerns about privacy and safety have become increasingly pressing. Machine unlearning offers one approach to addressing these concerns by removing designated information from trained models while preserving unrelated capabilities. However, fragmented implementations and evaluation protocols, incomplete robustness testing, and limited understanding of metric reliability make progress in MLLM unlearning difficult to assess systematically. We introduce Open-MMUnlearning, an open-source, extensible framework that integrates target-model preparation, multimodal data processing, unlearning, and evaluation through shared interfaces and structured configurations. The framework supports five benchmarks spanning privacy, safety, and copyright, eight MLLMs from four model families, and twelve unlearning methods. Its evaluation suite jointly assesses forgetting effectiveness, retained utility, and robustness to model interventions, adversarial inputs, and membership inference attacks. Using a common evaluation protocol, we compare ten representative unlearning methods. In this comparison, GD and MIP-Editor tie for the highest overall score: GD achieves the highest Forget Quality, while MIP-Editor preserves more Model Utility. We further introduce a metric meta-evaluation protocol that tests faithfulness using models with controlled exposure to target knowledge and robustness under quantization and relearning. Among the thirteen evaluated metrics, BLEU achieves the highest aggregate reliability score. KS-Test attains the highest faithfulness AUC but performs less well on robustness. Together, the framework and these findings support reproducible comparison of MLLM unlearning methods and systematic assessment of evaluation reliability.

Reasoning-Token Spikes Under Prompted Untruthful Responding in Large Language Models

在大型语言模型中,提示下的不真实回应下的推理令牌峰值
Morales, Maverick, Dominik, Tomáš, Gao, Vermut, Shirey, Katrina, Rimkevičius, Paulius, Schurger, Aaron, Maoz, Uri
Abstract
Monitoring the chain-of-thought of reasoning artificial intelligence (AI) models remains a key approach to detecting deception and other forms of misbehavior in such models. However, semantic chain-of-thought monitoring depends on reasoning traces being legible and sufficiently faithful to the underlying computations that produced the model's behavior, not to mention accessible. Moreover, there is increasing evidence that chain-of-thought outputs may soon become illegible or unfaithful, if they even remain accessible. Based on cognitive load theory, we investigate a lower-bandwidth signal -- the number of reasoning tokens generated -- which does not require access to the content of the reasoning trace. Three reasoning-capable large language models answered 210 multiple-choice questions -- across analytic, descriptive, and normative reasoning types as well as moral and non-moral domains -- under system prompts instructing them to respond truthfully, falsely, or without regard for truth. Across all three models, truth-directed responding elicited fewer reasoning tokens than both lie-directed and truth-indifferent responding. These findings show that explicitly prompted untruthful response policies can produce robust group-level differences in test-time reasoning-token use. While not yet establishing reasoning-token count as a detector of spontaneous deception or general misalignment, our results are a proof of concept that it can serve as a simple, content-independent candidate signal for differentiating untruthful from truthful model behavior when raw reasoning traces are unavailable or unreliable. Future work should test instance-level detection rates, out-of-distribution generalization, learned deceptive policies, hidden objectives, and robustness under adversarial pressure.

监测推理人工智能(AI)模型的思维链仍然是检测这些模型中欺骗和其他不当行为的关键方法。然而,语义思维链的监测依赖于推理痕迹的可读性和对产生模型行为的基础计算的充分忠实,更不用说可访问性。此外,越来越多的证据表明,如果思维链输出仍然可访问,它们可能很快变得不可读或不忠实。基于认知负荷理论,我们研究了一种低带宽信号——生成的推理令牌数量——这不需要访问推理痕迹的内容。三个具有推理能力的大型语言模型在系统提示下回答了210个多项选择题——涵盖分析性、描述性和规范性推理类型以及道德和非道德领域——提示它们真实、虚假或不考虑真相地回应。在所有三个模型中,面向真相的回应产生的推理令牌数量少于面向谎言和不考虑真相的回应。这些发现表明,明确提示的不真实回应策略可以在测试时推理令牌的使用上产生显著的群体级差异。尽管尚未将推理令牌计数确立为自发欺骗或一般不一致的检测器,但我们的结果证明了它可以作为一种简单的、与内容无关的候选信号,用于区分不真实与真实的模型行为,尤其是在原始推理痕迹不可用或不可靠的情况下。未来的工作应测试实例级检测率、分布外泛化、学习的欺骗策略、隐藏目标以及在对抗压力下的鲁棒性。

SOTA: Stock Options Trading Agents Guided by Option-Implied Return Distributions

SOTA:基于期权隐含收益分布的股票期权交易代理
Xie, Yizhen, Liu, Mengyang
Abstract
As option markets grow and AI advances, agentic systems for option trading are gaining increasing attention. Language-model-based agents can reason over contextual information such as news, but option trading presents a particularly challenging decision problem: a single stock can have thousands of contracts, and the agent must decide both which contracts to trade and how to combine them. Existing approaches often sidestep this complexity by restricting the policy to a fixed strategy structure, such as a straddle, limiting their ability to switch strategies as market conditions change. We present SOTA (Stock Options Trading Agents), an agentic trading framework for structured option-strategy selection. SOTA abstracts the large option universe into strategy-level decisions while deterministic resolvers handle portfolio implementation. We develop SOTA by post-training Qwen3.8-27B with supervised fine-tuning followed by reinforcement learning. SOTA is evaluated on options on nine large-cap U.S. equities and SPY against rule-based and machine-learning strategy selectors in the same trading environment. Over a six-month out-of-sample period, SOTA earns an 18.3% total return with a Sharpe ratio of 1.60 and a maximum drawdown of 8.96%. We also document an asymmetric role of news: news improves frontier-teacher trajectories, but retaining news during reinforcement learning reduces out-of-sample return from 18.3% to -2.7%.

RunningTab: Direct Workspace Interaction with Environment-Side Tabs

RunningTab:与环境侧标签的直接工作区交互
Baek, Jinheon, Jeong, Soyeong, Choi, Yumin, Han, Dongsu, Hwang, Sung Ju
Abstract
Much knowledge work produces new deliverables from files a workspace already holds, and LLM agents are beginning to take such work over. Through direct corpus interaction, an agent can search and read any of those files from a terminal with no indexing, and producing a deliverable from many of them in this way is what we call direct workspace interaction (DWI). Reaching the files, however, is only half the task: nothing keeps track of what the task asks for, what has been read, and what was listed but never opened, all of which slip through the context window without leaving a trace, so an agent may extract a figure and still deliver a report without it. To address this, we present RunningTab, a framework that equips direct workspace interaction with an environment-side tab: a per-task record of what the task still owes, kept by the environment alongside the agent. Specifically, the agent adds its requirements, while the environment records every file read as an excerpt with its provenance and every listed but unopened file as a candidate; the agent can then see each requirement beside its best-matching excerpts and top unopened candidates, resolve it against matching content or set it aside with a reason, and, should it try to finish with requirements still open, receive them in a finish check. We validate RunningTab on three benchmarks with three LLMs, where it consistently outperforms plain DWI and baselines that keep the record in the model, while its tab usually holds the values a deliverable needs once seen.

许多知识工作从工作区中已有的文件中生成新的交付物,而大型语言模型(LLM)代理开始接管这类工作。通过直接的语料库交互,代理可以从终端搜索和读取这些文件,而无需索引,以这种方式从多个文件中生成交付物,我们称之为直接工作区交互(DWI)。然而,访问文件仅仅是任务的一半:没有任何机制跟踪任务的要求、已阅读的内容以及列出但从未打开的文件,所有这些信息都在上下文窗口中悄然流失,因此代理可能提取了一个图形,却仍然交付了没有包含该图形的报告。为了解决这个问题,我们提出了RunningTab,一个为直接工作区交互配备环境侧标签的框架:一个按任务记录的任务所需内容,由环境与代理共同维护。具体而言,代理添加其需求,而环境记录每个已读文件的摘录及其来源,以及每个列出但未打开的文件作为候选项;代理可以在其最佳匹配摘录和未打开候选项旁边查看每个需求,针对匹配内容进行解决或以理由将其搁置,并且如果在仍有未完成需求的情况下尝试结束,将在结束检查中接收这些需求。我们在三个基准测试中验证了RunningTab,使用三种LLM,其表现始终优于普通的DWI和将记录保存在模型中的基线,而其标签通常在被查看后持有交付物所需的值。

Before They Can Solve: Predicting Post-Training Coding-Agent Performance from Base Models

Abstract
How can we predict which base checkpoint is worth an expensive round of agentic post-training? End-to-end pass@$K$ tests whether successful behavior already appears in a base model's distribution, but it is a poor fit for agentic coding: many base checkpoints cannot reliably produce the well-formed tool invocation required to complete a task end-to-end. Single-shot or short-horizon tasks avoid these tool-calling failures by collapsing a multi-step interaction into a fixed prompt and a single patch, but they sidestep the core capability we care about: maintaining coherent state over many tool-using steps as the repository evolves. To bridge this gap, we treat successful post-trained agent trajectories as a lookahead signal of base-model potential. Replaying each trajectory and rerunning tests after every code-changing step identifies the decisive step: the first step whose cumulative patch flips the repository from failing to passing, certifying that the recorded action solves the task given the prior context. Motivated by a coverage principle for agentic traces, we build three screens at this step that do not require a base checkpoint to drive the harness from a cold start: (i) Decisive-Action BPB (bits per byte) measures the probability mass on the certified action, (ii) Patch MCQ tests the checkpoint's choice between that action and alternatives rejected by the same verifier, and (iii) prefix-conditioned pass@$K$ evaluates support for functionally-correct generations and credits any continuation that the tests accept. Across ten pairs of public base and post-trained models, all three screens rank the cohort in close agreement with post-trained SWE-bench Verified pass@$1$. As our methods need only a benchmark's successful trajectories and its verifier, they can be applied to turn future agentic coding benchmarks into base-model evaluations.

EmbodiedRSI: Active Continual Robot Learning Through Hypothesis-Guided Co-Evolution

EmbodiedRSI:通过假设引导的共同进化实现主动持续机器人学习
Song, Python, Liang, Zhixuan, Fu, Kelsey, Wang, Mengdi, Yang, Junfeng, Liu, Shilong
Abstract
Robot foundation models provide strong visuomotor control, yet their performance can degrade when object positions or task instructions change. Further improvements often require post-training on substantial robot data, which can be costly to collect through methods such as teleoperation. Agentic harnesses can adapt around the model, but current self-evolving harnesses use robot trials inefficiently when deciding which code and skill changes to pursue. We introduce EmbodiedRSI, a self-evolving agentic harness that autonomously decides where to explore next and turns the resulting physical interaction into improved code and skills. EmbodiedRSI realizes this through a Fast-Slow Dual-System Architecture, in which competing code and skill hypotheses are maintained in a Hypothesis Graph. Value-of-Information Experiment Selection chooses physical experiments that can distinguish these hypotheses. Their outcomes guide Code-Skill Co-Evolution. The Slow System builds Hierarchical Memory, and Reward-Grounded Memory Learning selects effective memory according to their value for later Fast-System improvement. On RoboCasa365, EmbodiedRSI reaches 77.0% overall success and 71.3% on Composite-Unseen, compared with 40.1% for the best baseline. EmbodiedRSI also reaches 86.8% overall success on LIBERO-Pro.

机器人基础模型提供强大的视觉运动控制,但当物体位置或任务指令发生变化时,其性能可能会下降。进一步的改进通常需要在大量机器人数据上进行后期训练,而通过遥操作等方法收集这些数据的成本可能很高。Agentic harnesses 可以围绕模型进行适应,但当前的自我进化 harnesses 在决定追求哪些代码和技能变更时效率较低。我们提出了 EmbodiedRSI,这是一种自我进化的 agentic harness,能够自主决定下一步探索的方向,并将由此产生的物理交互转化为改进的代码和技能。EmbodiedRSI 通过快速-慢速双系统架构实现这一目标,其中在假设图中维护着竞争的代码和技能假设。信息价值实验选择(Value-of-Information Experiment Selection)选择能够区分这些假设的物理实验。实验结果指导代码-技能共同进化(Code-Skill Co-Evolution)。慢速系统构建层次记忆(Hierarchical Memory),而基于奖励的记忆学习(Reward-Grounded Memory Learning)根据其对后续快速系统改进的价值选择有效的记忆。在 RoboCasa365 上,EmbodiedRSI 达到了 77.0% 的整体成功率和 71.3% 的复合未见任务成功率,而最佳基线仅为 40.1%。在 LIBERO-Pro 上,EmbodiedRSI 的整体成功率也达到了 86.8%。超越基准性能,EmbodiedRSI 实现了零样本迁移到现实世界机器人,在多个具有挑战性的任务中取得了 71.3% 的整体成功率。

Validity Without Ground Truth: What Stated-Preference Economics Offers the Evaluation of Language Models

没有真实值的有效性:陈述偏好经济学对语言模型评估的贡献
Alexander, Daniel Robert Kling, Kling, Catherine Louise
Abstract
Many of the questions now put to large language models have no correct answer to score against: what a policy is worth, which option a user should choose, how to weigh competing values. Stated-preference economics has faced this problem for decades. It judges survey responses without knowing the true value, through a framework of validity and related concepts: content, construct, and criterion validity, reliability, incentive compatibility, and consequentiality. We argue that this framework is a general method for evaluating language models, and we set out what each concept means for LLM evaluation. We demonstrate the approach using a published water-quality stated preference economic valuation survey (Vossler et al. 2023) administered to six models. In this economic application, the validity tests take the form of predictions from economic theory: demand should slope down, and willingness to pay should respond to the scope of the good and to income. The tests separate the models sharply. Two older models fail the most basic test at a household income level of \$75,000, and the two newest pass every test of theoretical validity we can score, but diverge on convergent validity. Passing validity tests shows that a model's answers are coherent, not that they are correct.

目前对大型语言模型提出的许多问题没有正确答案可供评分:政策的价值、用户应选择的选项、如何权衡竞争价值。陈述偏好经济学在几十年来一直面临这一问题。它在不知道真实价值的情况下评估调查响应,通过有效性及相关概念的框架:内容有效性、构念有效性、标准有效性、可靠性、激励兼容性和结果性。我们认为这一框架是评估语言模型的一种通用方法,并阐明了每个概念对大型语言模型评估的意义。我们使用一项已发布的水质陈述偏好经济估值调查(Vossler et al. 2023)来展示这一方法,该调查针对六个模型进行。 在这一经济应用中,有效性测试以经济理论的预测形式出现:需求应呈下降趋势,支付意愿应对商品的范围和收入做出反应。测试显著区分了模型。两个较旧的模型在家庭收入为75,000美元的基本测试中失败,而两个最新的模型通过了我们可以评分的每一个理论有效性测试,但在趋同有效性上存在分歧。通过有效性测试表明模型的答案是一致的,而不是正确的。

RECAST: Learning to Compute the Right Context through Adaptive Evidence Routing

RECAST:通过自适应证据路由学习计算正确的上下文
Hao, Yilun, Sayana, Krishna, Ye, Isabella, Ren, James S, Sodhi, Sukhdeep, Boutilier, Craig, Fan, Chuchu
Abstract
Large language models are increasingly applied to tasks grounded in long, heterogeneous information sources. Conventional Retrieval-Augmented Generation (RAG) relies on fixed similarity-based retrieval, while agentic variants adapt queries and tool use but remain largely retrieval-centric. However, in many tasks, the evidence required for a solution is not explicitly present in any single source item. Instead, it must be derived through filtering, aggregation, or computation across multiple source items. In this work, we introduce RECAST (Routing Evidence through Computation, Access, and Synthesized Tools), a learned framework that formulates evidence construction as a sequential decision process over heterogeneous retrieval and computation operations, allowing evidence to be actively derived rather than merely retrieved. A lightweight RouterLM iteratively selects and formulates primitive operations or specifies customized operations for a frozen CompilerLM to translate into executable code. Once it judges the evidence sufficient, RouterLM passes the accepted evidence to a frozen AnswerLM to produce the final solution. We train RouterLM with supervised fine-tuning (SFT) followed by group relative policy optimization (GRPO). Across six heterogeneous benchmark families, RECAST achieves a mean success rate of 75.6%, outperforming the strongest large-model baseline by 15.9%. Moreover, training enables the Qwen3.5-9B RouterLM to outperform a training-free Gemini 3.5 Flash RouterLM by 5.0%. On three held-out benchmarks, RECAST improves over the strongest baseline by 15.0% on average, demonstrating strong zero-shot generalization across tasks and heterogeneous source representations.

大型语言模型越来越多地应用于基于长篇异构信息源的任务。传统的检索增强生成(RAG)依赖于固定的基于相似性的检索,而代理变体虽然能够适应查询和工具使用,但仍然主要以检索为中心。然而,在许多任务中,解决方案所需的证据并不明确存在于任何单一源项中。相反,这些证据必须通过对多个源项进行过滤、聚合或计算来推导。在本研究中,我们引入了RECAST(通过计算、访问和综合工具路由证据),这是一个将证据构建形式化为异构检索和计算操作的顺序决策过程的学习框架,允许证据被主动推导而不仅仅是检索。一个轻量级的RouterLM迭代选择和制定原始操作,或为一个冻结的CompilerLM指定自定义操作,以将其转换为可执行代码。一旦RouterLM判断证据足够,就将接受的证据传递给一个冻结的AnswerLM,以生成最终解决方案。我们通过监督微调(SFT)训练RouterLM,随后进行组相对策略优化(GRPO)。在六个异构基准系列中,RECAST的平均成功率达到75.6%,比最强大的大型模型基线高出15.9%。此外,训练使得Qwen3.5-9B RouterLM在表现上超越了无训练的Gemini 3.5 Flash RouterLM,提升了5.0%。在三个保留的基准测试中,RECAST在平均上比最强基线提高了15.0%,展示了在任务和异构源表示上的强大零-shot泛化能力。

SciExam for ENSO: Can AI Agents Build Climate Models?

SciExam for ENSO:人工智能代理能构建气候模型吗?
Zhang, Yinling, Liu, Langchen, Xiu, Dongbin, Zou, Xueyan, Kuang, Xu, Wang, Mengdi, Liu, Shilong
Abstract
Language-model agents are increasingly asked to carry out open-ended scientific research, yet their results are usually graded against a known answer, a rubric, or a language-model reviewer, none of which can tell whether a new scientific model is valid. The AI Science Exam for El Nino-Southern Oscillation (SciExam for ENSO) is a benchmark in which agents build low-order stochastic models of ENSO, the dominant mode of interannual climate variability, from real observations. Within a six-hour budget, agents process the observations, write their own diagnostics, which are then frozen, and develop a model using only these diagnostics as feedback. Hidden graders then test whether the model reproduces ENSO's statistics, recovers unobserved variables, and forecasts held-out years, and score a published model in the same way. Across twelve agent systems, six produce models that score higher than the published model, mainly through better reconstruction and forecasting. The simplified forms of the stronger models are each compatible with one of the two competing explanations of ENSO's warm-cold asymmetry, an open debate that the task never mentions. Controlled runs of the top system under varied information suggest that its scores do not come from recalling the dated observational record and that the information it receives shapes how it builds its model. SciExam for ENSO can thus evaluate agent research where no answer is known, and the results suggest that agents can already build competitive models whose structures bear on questions that scientists still debate.

RoboJEPA: Scaling Robotic Latent World Models

RoboJEPA:扩展机器人潜在世界模型

Abstract
Latent world models have shown a remarkable ability to predict future states and to plan in the real world. In practice, however, we lack a principled way to estimate how their capabilities scale with model size, data, and compute, an open problem that slows progress in the field. In this work we present RoboJEPA, a world model based on the Joint Embedding Predictive Architecture (JEPA) and trained on a large-scale dataset spanning 12 robotic embodiments. We show that RoboJEPA's imagination error, the error of its latent rollouts, follows a second-order power law in compute, allowing us to predict model quality well beyond the scale at which the law is fit. We further show that downstream robotic planning performance improves predictably with compute, and that imagination error is strongly correlated with it, making it a reliable proxy for real-robot evaluation. Finally, we demonstrate that latent world models can be deployed zero-shot as robotic agents, planning toward a single goal image to solve tasks requiring long-horizon planning on real hardware. We release all model checkpoints together with our training and robot deployment code. To our knowledge, this is the first work to establish scaling laws for multi-embodiment robotic world models trained on real robot data, and RoboJEPA, at 8B parameters, is the largest JEPA predictor model trained to date.

Tokka-Bench: Evaluating Tokenizers Across 100 Natural and 20 Programming Languages

Tokka-Bench:跨越100种自然语言和20种编程语言评估分词器
Gubler, Ben
Abstract
Large language models rely on subword tokenizers whose quality varies across languages, yet no standardized multi-metric framework exists for broad comparative evaluation. We introduce Tokka-Bench, an open-source framework that evaluates tokenizers on five complementary metrics -- bytes per token, unique token coverage, subword fertility, word-split rate, and vocabulary composition -- across 100 natural languages (30+ scripts) and 20 programming languages, using language-aware segmentation adapted to each writing system. Comparing seven BPE tokenizers (GPT-2, GPT-4, gpt-oss, Llama 3.1, Gemma 3, Qwen3, and Kimi K2) within individual languages, we find that vocabulary allocation strategy matters more than raw vocabulary size, and that programming-language efficiency has converged among recent tokenizers despite divergent natural-language profiles. The framework, data, and interactive dashboard are publicly available.

Child ASR Adaptation with Adult Retention: An Empirical Study

儿童自动语音识别适应与成人保留:一项实证研究
Lachemat, Houssam Eddine-Othman, Chowdhury, Shammur Absar
Abstract
Automatic Speech Recognition (ASR) systems often underperform for children and non-native speakers, while adapting adult ASR models to child speech can cause adult-speech forgetting. We study child ASR adaptation with adult retention across Arabic and English. We compare full fine-tuning, LoRA, and post-hoc weight-space merging across encoder--decoder, encoder--CTC, and AudioLLM-based ASR systems. Experiments use Arabic native and non-native child speech, English MyST child speech, and adult benchmarks from MGB-2 and LibriSpeech test-clean. We evaluate recognition quality with WER and quantify the adaptation--retention trade-off using Retention Index, Child Adaptation Gain, and Adaptation Recovery. Results show that child adaptation is necessary, especially for non-native Arabic and English child speech, but direct adaptation often reduces adult ASR performance. Bilingual adaptation is more stable than language-specific adaptation. Weight-space merging often improves the trade-off, especially for encoder--CTC, Whisper, and AudioLLM-based ASR, with LERP favoring adult retention and TIES recovering stronger child gains. For the encoder--decoder model, direct bilingual fine-tuning remains strongest in raw WER.\footnote{Code, and models are available at https://github.com/qcri/Child-ASR-Adaptation.

When Forgetting Looks Like Improvement: Metric Masking in Streaming Diarizer Adaptation and the Price of Rehearsal

当遗忘看似改善:流式说话人分离适应中的度量掩蔽及其排练代价
Yu, Mo, Liu, Yang, Qian, Jing
Abstract
Small-data adaptation can improve speech detection while degrading speaker attribution. We study this discrepancy in a released streaming diarizer adapted on 7.5 h of two-party conversation and evaluated across six corpora. Adaptation substantially improves in-domain diarization performance and transfers to an independent corpus. However, this improvement is not consistent across evaluation scenarios as the additional confusion is mainly associated with impaired temporal identity consistency rather than speaker-count errors. A local-remapping diagnostic reveals different patterns of identity degradation across corpora, indicating that adaptation may alter how streaming models maintain speaker assignments over time. Rehearsal reduces the observed degradation but reduces the cross-domain transfer performance. These results highlight the need to jointly evaluate detection accuracy, identity consistency, and retention behavior when adapting streaming diarization systems.

小数据适应可以提高语音检测的准确性,但却降低了说话人归属的准确性。我们研究了这一差异,分析了在7.5小时的双人对话上适应的流式说话人分离系统,并在六个语料库上进行了评估。适应显著提高了领域内的说话人分离性能,并能够迁移到独立的语料库。然而,这种改善在不同评估场景中并不一致,因为额外的混淆主要与时间身份一致性的损害有关,而不是说话人数量错误。局部重映射诊断揭示了不同语料库中身份退化的不同模式,表明适应可能改变流式模型随时间维持说话人分配的方式。排练减少了观察到的退化,但也降低了跨领域的迁移性能。这些结果强调了在适应流式说话人分离系统时,需要共同评估检测准确性、身份一致性和保持行为。

Emo-Jev: Probabilistic Reasoning for Emotion Classification with Jev

Emo-Jev:基于Jev的情感分类概率推理
Zhang, Yazhou, Yu, Junhao
Abstract
Jev offers an alternative interface for language understanding: given an input and predefined questions, it returns probabilistic decisions rather than free-form responses. Whether this interface can support effective reasoning for text classification against leading LLMs remains an open questions. We introduce Emo-Jev, a training-free framework with two complementary implementations. Emo-Jev-D decomposes classification into task-specific atomic judgments and composes their probabilities into a final prediction. Emo-Jev-SC constructs multiple judgment paths from complementary perspectives and aggregates their predictions into a consensus decision. We evaluate Emo-Jev on eight datasets spanning sentiment analysis, emotion recognition, sarcasm detection and humor detection, comparing against direct Jev classification and five SoTA LLMs under input/output and chain-of-thought reasoning. Standard Jev achieves 62.93\% average macro-F1 versus 67.28\% for the strongest LLM baseline, with lower observed latency and generally lower cost.

CoDR: Training-Free Confidence-Drift Remasking for Diffusion Language Models

CoDR:无训练的信心漂移重掩码用于扩散语言模型
Wu, Yue, Zhang, Qinghe, Zhang, Yu, Huang, Jian
Abstract
Masked diffusion language models (MDLMs) decode by repeatedly committing tokens to masked positions, but these commitments are usually irreversible. A token chosen under sparse, partial context is kept fixed, even when later context no longer supports it. Existing samplers mainly decide when to commit a token, but rarely check whether an already committed token should still be kept, allowing early mistakes to propagate. We trace this issue to confidence drift, where the model's confidence in a committed token drops from its sparse commit-time context to the denser context available later. Based on this signal, we propose CoDR (Confidence Drift Remasking), a training-free and sampler-agnostic refinement pass. CoDR estimates drift for all committed positions in only k forward passes via k-partition probing, then remasks and regenerates only the tokens the model no longer endorses. Across two backbones, four reasoning and coding tasks, and three base samplers, CoDR improves average accuracy across all evaluated model-sampler configurations and improves most individual task settings with modest overhead. Controlled experiments show that the gains come from targeted confidence-drift remasking rather than extra compute alone, and that CoDR uses far fewer forward passes than prior remasking methods. Code is available at https://github.com/YueWu0301/CoDR.

掩码扩散语言模型(MDLMs)通过反复将标记提交到掩码位置来解码,但这些提交通常是不可逆的。在稀疏的部分上下文下选择的标记保持不变,即使后续的上下文不再支持它。现有的采样器主要决定何时提交标记,但很少检查已提交的标记是否仍应保留,从而导致早期错误的传播。我们将这个问题追溯到信心漂移,即模型对已提交标记的信心从稀疏的提交时上下文下降到后续可用的更密集的上下文。基于这一信号,我们提出了CoDR(信心漂移重掩码),这是一种无训练且与采样器无关的精炼过程。CoDR通过k-分区探测在仅k次前向传递中估计所有已提交位置的漂移,然后仅重掩码和再生成模型不再支持的标记。在两个基础模型、四个推理和编码任务以及三个基础采样器中,CoDR提高了所有评估的模型-采样器配置的平均准确性,并在大多数单个任务设置中以适度的开销取得了改善。控制实验表明,增益来自于针对性的信心漂移重掩码,而不仅仅是额外的计算,并且CoDR使用的前向传递次数远少于先前的重掩码方法。代码可在 https://github.com/YueWu0301/CoDR 获取。

Leveraging LLM-Generated Explanations for Detecting Emotionally Rewritten Fake News

利用大语言模型生成的解释检测情感重写的假新闻
Guo, Yupei, He, Jiajun, Shi, Xiaohan, Toda, Tomoki, Yang, Zekun, Wang, Bowen, Taniguchi, Yukinobu
Abstract
The spread of fake news may cause severe social consequences. Existing fake news detection methods mainly focus on stylistic variations or incorporate external information such as explanations. However, news articles are often rewritten under different emotional backgrounds while preserving their underlying factual claims, which may affect the robustness of detection models. In this work, we investigate fake news detec- tion under fact-preserving emotional variations. To study this problem, we construct emotion-rewritten test sets and generate explanations from the original news articles as stable background knowledge. We then propose a Gated Cross Attention (GCA) framework that adaptively integrates emotionally rewritten news with the corresponding explanations, enabling the model to focus on informative explanation content while reducing potential mismatches caused by emotional reframing. Experiments on PolitiFact, GossipCop, and LUN demonstrate that the proposed method achieves notable improvements under multiple emotional conditions on PolitiFact and LUN, while maintaining competitive performance on GossipCop. We further analyze the effects of explanation guidance and gating mechanisms under different emotional conditions. Our code and data are available at: https://github.com/Flulike/fakenews gca .

Beyond the Sycophancy Score: How Task, Model, and Pressure Shape LLM Yielding

超越谄媚评分:任务、模型和压力如何影响大型语言模型的表现
Yang, Guang, Hosseinmardi, Homa, Liu, Fengchen, Ghasemian, Amir
Abstract
Large language models (LLMs) often abandon a correct answer, or endorse a user's position, once the user pushes back. This behavior, called sycophancy, is usually reported as a single rate per model, which says little about when it happens or how a user can avoid it. We study the conditions that produce it with 103,939 graded replies from ten configurations: eight LLMs with reasoning disabled, and two of them again with maximum reasoning, all facing the same 200 items, 13 pressure conditions, and four-turn conversations, with every reply labeled by two independent LLM judges. We find that the dominant factors are how costly it is for the model to verify the user's claim, and whether a trained guardrail covers it. Removing this task factor from a logistic model costs 0.485 of McFadden $R^2$, against 0.139 for model family and 0.009 for pressure tactic. Anchored facts are almost never conceded (1.3%), while adoption on logic puzzles rises with the number of clues needed to refute the pushed answer. Personal choices are endorsed in 77.0% of conversations. Most concessions on hard items come from models that cannot reliably solve them; models that can solve them rarely give the answer up. For both models tested, maximum reasoning removes these concessions completely: adoption on deep puzzles falls from 19.2% and 12.5% to 0%. Fallacious or emotional framing adds nothing beyond plain repetition. Three human annotators agree with the judges' consensus on 118/120 calibration items. These results give practical rules for reliable use: simplify hard-to-verify problems and reason deeply, state the question rather than one's preferred answer, ask for evidence on open questions, and choose models by their measured guardrail profile.

大型语言模型(LLMs)在用户反驳时,往往会放弃正确答案或支持用户的立场。这种行为被称为谄媚,通常以每个模型的单一比率报告,这对其发生的时机或用户如何避免它几乎没有提供信息。我们通过分析来自十种配置的103,939条评分回复来研究产生这种行为的条件:八个禁用推理的LLM,以及其中两个在最大推理下的表现,所有模型面对相同的200个项目、13种压力条件和四轮对话,每条回复由两个独立的LLM评审标记。我们发现,主导因素是模型验证用户主张的成本,以及是否有训练好的保护措施覆盖该主张。从逻辑模型中移除这一任务因素导致McFadden $R^2$损失0.485,而模型家族的损失为0.139,压力策略的损失为0.009。锚定事实几乎从不被让步(1.3%),而在逻辑难题中,推翻被推动答案所需线索的数量越多,采纳率就越高。个人选择在77.0%的对话中得到支持。大多数在困难项目上的让步来自于无法可靠解决这些问题的模型;能够解决这些问题的模型则很少放弃答案。对于测试的两个模型,最大推理完全消除了这些让步:在深度难题上的采纳率从19.2%和12.5%降至0%。虚假或情感框架除了简单重复外没有增加任何内容。三位人类注释者在118/120个校准项目上与评审的共识达成一致。这些结果为可靠使用提供了实用规则:简化难以验证的问题并进行深入推理,陈述问题而非个人偏好答案,针对开放性问题请求证据,并根据测量的保护措施特征选择模型。

Beyond Risk Prediction: Evidence Grounding and Psychosocial Factor Verification for Explainable Suicide Risk Assessment

超越风险预测:可解释自杀风险评估的证据基础和心理社会因素验证
Hu, Tianle, Peng, Chen, Tsai, Yi-Hsin, Tung, Takshing Andy, Sun, Bingyang, Wang, Yenjou
Abstract
Identifying suicide risk from social networking services (SNS) posts is important for detecting suicide-related signals in online environments. However, risk classification alone provides limited insight into the textual evidence and psychosocial factors behind a prediction. Based on the IEEE BigData 2026 Explainable Suicide Risk Detection Challenge, this study presents a framework consisting of Risk Assessment, Evidence Grounding, and Factor Identification. Risk Assessment uses length-based routing to accommodate posts of different lengths. Evidence Grounding identifies supporting phrases and uses a Risk-Evidence constraint to maintain consistency with the Risk prediction. For Factor Identification, two verifiers are used. The Taxonomy Verifier focuses on factor semantics, whereas the Evidence-Aware Verifier uses factor-specific lexical-semantic cues to select informative positive training units. Their prediction probabilities are combined to produce the final factor predictions. The three tasks are evaluated using task-specific F1 score measures. Risk Assessment achieved a Weighted F1 of 0.8088, Evidence Grounding achieved a test Macro row F1 of 0.7605, and Factor Identification achieved a Macro F1 of 0.5562. The results show that the framework can provide risk predictions, along with supporting textual evidence and fine-grained information on psychosocial factors. Overall, the proposed framework extends suicide-risk assessment beyond risk-level prediction and provides a more interpretable analysis of SNS posts.

Bai, Yiping
Abstract
Quantifying language distance among closely related languages remains a core challenge in quantitative linguistics. Our previous work [1] introduced QuanLing (Quantitative Linguistics via Pretrained Language Models), a quantitative framework combining language distance metrics (sentence embedding distance, tokenization fragmentation rate) with language property analysis (MLM prediction probability), validated on North Germanic (Danish, Norwegian Bokm{\aa}l, Swedish). This paper extends QuanLing to Western Romance--French, Portuguese, Spanish, Italian--testing cross-branch applicability with the same metric family and aggregation protocol as our North Germanic study, adapted for four languages (English anchor, quadruplet construction). Using 150 four-language parallel sentences, we compute LaBSE sentence embedding distances, tokenization fragmentation rates from four monolingual BERT tokenizers, and mBERT masked language model mutual intelligibility. Results show that Portuguese--Spanish are closest (LaBSE distance 0.0229), French--Italian most distant (0.0338); LaBSE and mBERT rankings agree on 4 of 6 pairs, confirming cross-model robustness. Western Romance shows a wider absolute distance span than North Germanic (0.011 vs. 0.008) but comparable relative ratios (1.48 vs. 1.67), consistent with longer divergence time. French exhibits notably higher MLM predictability (36.12% top-1 accuracy vs. 29.28% for Italian), reflecting its orthography--phonology decoupling. This cross-branch validation provides further evidence for QuanLing's generalizability beyond a single language branch.

在紧密相关语言之间量化语言距离仍然是定量语言学中的一个核心挑战。我们之前的研究[1]引入了QuanLing(通过预训练语言模型的定量语言学),这是一个结合语言距离度量(句子嵌入距离、分词碎片率)与语言属性分析(MLM预测概率)的定量框架,已在北日耳曼语(丹麦语、挪威博克马尔语、瑞典语)上进行了验证。本文将QuanLing扩展到西方罗曼语系——法语、葡萄牙语、西班牙语、意大利语——测试相同度量家族和聚合协议的跨分支适用性,适用于四种语言(英语锚点、四元组构造)。使用150个四语言平行句子,我们计算了LaBSE句子嵌入距离、来自四个单语BERT分词器的分词碎片率,以及mBERT掩蔽语言模型的相互可理解性。结果显示,葡萄牙语与西班牙语之间的距离最近(LaBSE距离0.0229),法语与意大利语之间的距离最远(0.0338);LaBSE和mBERT的排名在6对中的4对上达成一致,确认了跨模型的稳健性。西方罗曼语显示出比北日耳曼语更大的绝对距离范围(0.011对比0.008),但相对比率相似(1.48对比1.67),与更长的分歧时间一致。法语的MLM可预测性显著更高(36.12%的顶级准确率对比意大利语的29.28%),反映了其正字法与音位学的解耦。这一跨分支验证为QuanLing在单一语言分支之外的普适性提供了进一步证据。

LRCC: Generalizing Low-Rank Compression with Conditional Computation

LRCC:通过条件计算推广低秩压缩
Fontanari, Thomas Vaitses, Rulli, Maximo Eduardo, Alvetreti, Federico, Genovese, Donatella, Scardapane, Simone
Abstract
Low-rank compression reduces the cost of pretrained language models by replacing linear transformations with low-rank factorizations. However, conventional methods use a fixed rank allocation during inference, assigning the same amount of compute regardless of the input token. We introduce Low-Rank Conditional Computation (LRCC), which adds token-dependent computation to pretrained models by training one lightweight router per Transformer block to select among a small set of nested low-rank paths. During training, the low-rank factors remain frozen, and only the routers are optimized. We evaluate LRCC on Llama and Qwen models for language modeling and zero-shot downstream tasks. Within the same average active-parameter budget, LRCC improves the predictive performance over static low-rank compression, including a 7.6 percentage-point gain in average downstream accuracy on Llama-2-7B over static methods. At matched batch-size-1 decoding latency, LRCC improves both perplexity and downstream accuracy on Llama-3.2-1B and remains competitive on Llama-2-7B, without specialized kernels. Finally, we assess the usefulness of assigning a token-wise path by analyzing the routers' path choices.

低秩压缩通过用低秩分解替代线性变换,降低了预训练语言模型的计算成本。然而,传统方法在推理过程中使用固定的秩分配,无论输入标记如何,都分配相同的计算量。我们提出了低秩条件计算(Low-Rank Conditional Computation, LRCC),通过为每个Transformer模块训练一个轻量级路由器,增加了依赖于标记的计算,以在一小组嵌套的低秩路径中进行选择。在训练过程中,低秩因子保持不变,只有路由器被优化。我们在Llama和Qwen模型上评估LRCC,以进行语言建模和零-shot下游任务。在相同的平均活跃参数预算内,LRCC在静态低秩压缩上提高了预测性能,包括在Llama-2-7B上相比静态方法提高了7.6个百分点的平均下游准确率。在匹配的批量大小为1的解码延迟下,LRCC在Llama-3.2-1B上提高了困惑度和下游准确率,并在Llama-2-7B上保持竞争力,而无需专门的内核。最后,我们通过分析路由器的路径选择来评估分配标记级路径的有效性。

Tiny-Scale Chinese BERT Pretraining: A Controlled Comparison of MLM, WWM, and MacBERT Strategies

小规模中文BERT预训练:MLM、WWM和MacBERT策略的对照比较
Bai, Yiping
Abstract
Pretraining strategies significantly impact the quality of language models, yet existing comparisons of Masked Language Modeling (MLM), Whole Word Masking (WWM), and MacBERT-style replacement have focused primarily on base-scale models (>=110M parameters). This paper presents a controlled comparison of these three strategies on a tiny-scale Chinese BERT model (4 layers, 256 hidden dimensions, 8.7M parameters). Under identical architecture, corpus (1.29M sentences from Chinese Wikipedia), and hyperparameters, we train three models from scratch and evaluate them across five intrinsic dimensions: perplexity, MLM hit rate, semantic discrimination, grammatical judgment, and contextual sensitivity. At tiny scale, MLM achieves the best overall intrinsic performance (winning 3 of 5 dimensions), while WWM excels in both perplexity (1.27 vs. 2.10, a 39.5% improvement) and MLM hit rate (22% vs. 16%). Notably, MacBERT under a severely limited synonym dictionary (222 entries, 3.3% coverage) exhibits severe perplexity degradation (47.23, 22x higher than MLM), yielding a ranking (MLM > WWM >> MacBERT) that differs markedly from the established base-scale conclusion (MacBERT > WWM > MLM). We further identify a critical evaluation pitfall: MacBERT achieves the lowest training loss (2.17) yet the highest perplexity (47.23), revealing that training loss alone is unreliable under mixed replacement strategies. All models and corpus are publicly available at https://huggingface.co/eebyp.

预训练策略对语言模型的质量有显著影响,但现有的对比研究主要集中在基础规模模型(>=110M参数)上,涉及掩码语言建模(MLM)、整体词掩码(WWM)和MacBERT风格替换。本文对这三种策略在一个小规模中文BERT模型(4层,256个隐层维度,8.7M参数)上进行了受控比较。在相同的架构、语料(来自中文维基百科的1.29M句子)和超参数下,我们从头开始训练了三个模型,并在五个内在维度上进行了评估:困惑度、MLM命中率、语义区分、语法判断和上下文敏感性。在小规模下,MLM在整体内在性能上表现最佳(在5个维度中赢得3个),而WWM在困惑度(1.27对比2.10,改善39.5%)和MLM命中率(22%对比16%)上表现优异。值得注意的是,在一个严重受限的同义词词典(222个条目,覆盖率3.3%)下,MacBERT表现出严重的困惑度退化(47.23,比MLM高出22倍),导致其排名(MLM > WWM >> MacBERT)与已建立的基础规模结论(MacBERT > WWM > MLM)显著不同。我们进一步识别出一个关键的评估陷阱:MacBERT虽然达到了最低的训练损失(2.17),但却有最高的困惑度(47.23),这表明在混合替换策略下,仅依赖训练损失是不可靠的。所有模型和语料均可在 https://huggingface.co/eebyp 获取。

Steering Follows Geometry, Not Labels: Emotion Directions in a Full-Duplex Speech Model

引导遵循几何,而非标签:全双工语音模型中的情感方向
Kuli, Pulak
Abstract
Full-duplex voice agents need to modulate emotion and delivery during real-time conversations, when de-escalating a complaint, carrying urgency in dispatch, softening a clinical result. Emotion and delivery control is well studied for TTS and turn based models through prompt-conditioned synthesis, reference-conditioned synthesis and activation steering; PersonaPlex controls identity in a duplex model but not affect. We study emotion steering in Moshi, a fully open sourced full-duplex speech language model, across four emotions, using mean-difference activation steering, which costs only a few vector additions per frame and no retraining. We show that emotion is linearly decodable from Moshi's residual stream, but activation steering is only partially achievable, and unevenly so; as happy, angry and surprise steer towards a shared direction while sad is distinctly steerable. We also show that the shared component across the three emotions cannot simply be projected away from all the emotions equally.

CARE: Certifying Acceleration for Vision-Language-Action Inference

CARE:视觉-语言-动作推理的加速认证
Liu, Rui, Zheng, Tong, Gu, Jindong, Wang, Zhipeng
Abstract
While vision-language-action (VLA) models have advanced rapidly, running them at every control step remains expensive. Prior work accelerates VLA inference using techniques like action chunking and visual-token pruning, typically evaluating based on latency and average task success. However, acceleration may discard information and break tasks the original policy would solve, a risk hidden by average metrics. Measuring these failures is challenging because action deviations compound over closed-loop trajectories, meaning task failure is only observable across full episodes. We therefore define an acceleration-induced failure via paired rollouts from identical initial conditions, tracking when the reference succeeds but the accelerated policy fails. To manage this, we introduce CARE, an approach for certified accelerator selection. CARE uses paired rollouts on a calibration set to provide finite-sample guarantees that acceleration-induced failure risk stays below a user-specified budget. It deploys the fastest certified candidate, falling back to the reference if none qualify. By relying only on terminal outcomes and measured compute, CARE applies unchanged across diverse acceleration mechanisms, while sequential testing and failure-triggered reference rollouts keep certification affordable. On four LIBERO suites with OpenVLA-OFT, CARE certifies $9.0$--$10.8\times$ speedups while guaranteeing (at $95\%$ confidence) that at least $85.8\%$ of reference-solved episodes are preserved. Under tight budgets, selectors without guarantees exceed the budget in up to $75\%$ of trials, whereas CARE stays within budget and its sequential form uses $78.9\%$ fewer rollouts than exhaustive evaluation. CARE further generalizes to flow-step reduction for $\pi_{0.5}$, and to Qwen3.5-9B and Llama-3.1-8B agents in Crafter.

尽管视觉-语言-动作(VLA)模型发展迅速,但在每个控制步骤中运行它们仍然成本高昂。之前的研究通过动作分块和视觉标记修剪等技术加速VLA推理,通常基于延迟和平均任务成功率进行评估。然而,加速可能会丢失信息并破坏原始策略能够解决的任务,这一风险被平均指标所掩盖。测量这些失败是具有挑战性的,因为动作偏差在闭环轨迹中会累积,这意味着任务失败仅在完整的回合中可观察到。因此,我们通过从相同初始条件的配对回放定义加速引起的失败,跟踪何时参考策略成功而加速策略失败。为了解决这个问题,我们引入了CARE,一种认证加速器选择的方法。CARE在校准集上使用配对回放,提供有限样本保证,确保加速引起的失败风险低于用户指定的预算。它部署最快的认证候选者,如果没有候选者符合条件,则回退到参考策略。通过仅依赖终端结果和测量计算,CARE在各种加速机制中保持不变,而顺序测试和失败触发的参考回放使认证变得经济可行。在四个LIBERO套件中使用OpenVLA-OFT,CARE认证了$9.0$--$10.8 imes$的加速,同时保证(在$95\%$的置信度下)至少$85.8\\%$的参考解决回合得以保留。在预算紧张的情况下,没有保证的选择器在多达$75\\%$的试验中超出预算,而CARE则保持在预算内,其顺序形式比全面评估使用$78.9\\%$更少的回放。CARE进一步推广到$ ext{flow-step}$减少的$ ext{π}_{0.5}$,以及在Crafter中的Qwen3.5-9B和Llama-3.1-8B代理。

Quad-State Safety Evaluation of Open-Weight Large Language Models on Non-Canonical Inputs

开放权重大型语言模型在非规范输入上的四状态安全评估
Maddula, Pavan
Abstract
Standard safety evaluations of large language models assess harmful requests written in canonical plain text, while models in real-world deployment routinely receive inputs containing emojis, altered spellings, encoded strings, and character-level variations. This work introduces the Adversarial Surface-Form Robustness Dataset (ASRD), comprising 2,100 prompts across seven distinct surface-form families. Five open-weight language models are evaluated across these prompts, producing 10,500 responses. The Quad-State Evaluation Rubric classifies each response into one of four outcomes: harmful compliance, safe response, comprehension failure, or indeterminate. Emoji and invisible Unicode variations cause almost no comprehension failure, with pooled harmful compliance of 20.27% and 17.20% against a 22.87% baseline that is driven mainly by Mistral 7B, whereas leetspeak, encoded wrappers, and hybrid transformations score 2.40%, 0.13%, and 2.40% while comprehension failure rises to 36.47%, 65.60%, and 34.47%. Inspection of raw model outputs reveals three response behaviors: hallucinated benignity, structural collapse, and language drift. Project page: www.pavanmaddula.com/quadstate

U-Space: Uncovering When and Why Uncertainty Arises in Language Models

U-Space:揭示语言模型中不确定性何时及为何产生
Braun, Tobias, Loose, Nils, Herzog, Alexander, Ceccatelli, Virginia, Rohrbach, Marcus, Eisenbarth, Thomas, Cavallaro, Lorenzo
Abstract
Large language models are informing decisions with ever-higher stakes. As the consequences of their errors grow, a central question becomes harder to ignore: how much can we trust an individual answer? Yet recognizing when to defer remains difficult because language models can present incorrect conclusions with fluent explanations and an authoritative tone. Uncertainty quantification seeks to address this disconnect by estimating the reliability of individual predictions. However, many existing methods require repeated generations or separately trained components, and their scalar estimates do not reveal where uncertainty arises or how it evolves during reasoning. Recent work has also shown that generation length can be strongly associated with uncertainty estimates and correctness, raising the question of how much of an estimator's predictive power comes from uncertainty-specific information rather than output length alone. Mechanistic interpretability offers a way to address these limitations by connecting human-interpretable concepts to intermediate model states. Building on this capability, we introduce the U-Space, a low-dimensional subspace that makes a model's evolving uncertainty measurable and interpretable. We identify semantic anchors for doubt and certainty, map their unembedding directions back into the residual space, and combine their contrasts into an orthogonal basis. The U-Lens projects each token state onto these basis vectors, yielding an interpretable token-level uncertainty map that can be inspected directly or aggregated into a scalar uncertainty score. Our approach requires no correctness labels, repeated generations, or training. Across reasoning benchmarks, its confidence score outperforms established baselines under both standard and length-controlled evaluation and transfers more reliably than supervised estimators.

大型语言模型正在影响越来越高风险的决策。随着错误后果的加剧,一个核心问题变得愈发难以忽视:我们能多大程度上信任单个答案?然而,识别何时应当推迟判断仍然困难,因为语言模型可以用流畅的解释和权威的语气呈现错误的结论。不确定性量化试图通过估计个别预测的可靠性来解决这一脱节。然而,许多现有方法需要重复生成或单独训练的组件,并且它们的标量估计并未揭示不确定性产生的具体位置或在推理过程中如何演变。最近的研究还表明,生成长度与不确定性估计和正确性之间可能存在强关联,这引发了一个问题:估计器的预测能力有多少来自于特定于不确定性的信息,而不仅仅是输出长度。机械可解释性提供了一种解决这些局限性的方法,通过将人类可解释的概念与中间模型状态连接起来。在此能力的基础上,我们引入了U-Space,一个低维子空间,使模型不断演变的不确定性可测量且可解释。我们识别出怀疑和确定性的语义锚点,将它们的去嵌入方向映射回残差空间,并将它们的对比结合成一个正交基。U-Lens将每个标记状态投影到这些基向量上,生成一个可解释的标记级不确定性图,可以直接检查或聚合成标量不确定性分数。我们的方法不需要正确性标签、重复生成或训练。在推理基准测试中,其置信分数在标准和长度控制的评估下均优于既定基线,并且比监督估计器更可靠地进行迁移。代码:https://github.com/s2labres/U-Space。

Same Text, Different Prediction: Serving-Context Nondeterminism in Text Classifiers

相同文本,不同预测:文本分类器中的服务上下文非确定性
Kasa, Santhosh Kumar, Kasa, Siva Rajesh, Negi, Sumit
Abstract
Deterministic inference is essential for reliable and trustworthy machine learning. Prior studies of text generation have shown that changing factors such as batch size, batch composition, hardware, or inference engine can alter the generated text, even when the prompt, model parameters, and sampling randomness are fixed. These differences have been attributed in part to floating-point non-associativity, shape-dependent kernel selection, and other implementation-level differences in numerical execution. However, it remains unclear whether, when, and to what extent the same factors affect text classification. We present a systematic study of serving-context non-invariance in text classifiers, which prior work has measured only through generated text. We train 180 models spanning discriminative, pseudo-generative, and fully generative classifier formulations and evaluate each across four categories of serving contexts, holding the checkpoint and the text fixed. Label stability does not imply score stability. Changing only the batch shape changes no labels across fp32 comparisons, yet under bf16 it moves up to 56.7 percentage points of predicted probability mass, with label changes concentrated at small margins. Fully generative classifiers change more labels than their discriminative counterparts under the same serving changes. We derive sufficient conditions for label stability under each serving change and give a separate mitigation for each mechanism. Our results identify and quantify the serving conditions that must be fixed for reproducible text classification.

确定性推理对于可靠和可信的机器学习至关重要。先前的文本生成研究表明,改变批量大小、批量组成、硬件或推理引擎等因素可以改变生成的文本,即使提示、模型参数和采样随机性保持不变。这些差异部分归因于浮点数非结合性、形状依赖的内核选择以及其他数值执行中的实现级差异。然而,目前尚不清楚相同因素在多大程度上、何时影响文本分类。我们对文本分类器中的服务上下文非不变性进行了系统研究,而之前的工作仅通过生成文本进行了测量。我们训练了180个模型,涵盖了判别式、伪生成式和完全生成式分类器的不同形式,并在四种服务上下文类别中评估每个模型,同时保持检查点和文本不变。标签稳定性并不意味着得分稳定性。仅改变批量形状在fp32比较中不会改变任何标签,但在bf16下则会移动多达56.7个百分点的预测概率质量,标签变化集中在小幅度的边际上。在相同的服务变化下,完全生成式分类器改变的标签数量多于其判别式对应物。我们推导了每种服务变化下标签稳定性的充分条件,并为每种机制提供了单独的缓解措施。我们的结果识别并量化了必须固定的服务条件,以实现可重复的文本分类。

Abstract
Multilingual LLM benchmarks omit Slovak, a morphologically rich West Slavic language of five million speakers, or cover it only by machine translation. We present sk-bench, a native-first Slovak benchmark with 30 datasets (33 scored task variants) across ten skill categories. Eleven resources are introduced or first packaged for generative-LLM evaluation, including IFEval-SK with Slovak-adapted instruction checkers and native Chiby/SKJ1 resources for Slovak grammar and morphology. We evaluate 55 open- and closed-weights models under one harness. The best open model trails proprietary APIs by 12.6 points. Model rankings are similar for native and translated closed-form data ($\rho\geq0.98$), though translation separates the strongest models less well. By contrast, human-authored and LLM-generated QA questions rank models differently ($\rho=0.72$). For Qwen3-14B, continued Slovak pretraining lowers the overall score by 13.9 points. A small instruction set restores three quarters of that loss. Test-time reasoning improves scores by 8.5 to 12.5 points for models of 9B and above. Together, these findings suggest four design lessons for other under-resourced languages: use native data where translation fails, plan instruction repair after language adaptation, enable test-time reasoning before scaling up, and avoid overinvesting in target-language prompts. We release the data and code at https://github.com/slovak-nlp/sk-bench

ToolRACER:一种用于代理训练和评估的稳健代理对话模拟资源

Abstract
Task-oriented conversational agents remain fragile under real world conversation scenarios as they rarely follow a predictable script, especially when users exhibit non-cooperative behavior. Existing function-calling benchmarks often emphasize successful, cooperative interactions and underrepresent adversarial conversation trajectories, thereby limiting the training resources available for developing robust agents. We present ToolRACER, a synthetic data generation pipeline that coordinates user, assistant and tool emulation models to generate and validated multi-turn interactions between a user and an agent. Using \sysn, we construct ToolRACERBench a robust multi-turn conversation benchmark spanning six domains, ranging over 55 varied personas, generating a validated corpus of 5.6K conversation trajectories, with approximately 66\% of conversations containing failure-prone conversation scenarios. We inject adversarial behaviors, producing validated conversational interaction trajectories that capture realistic, robust scenarios. We evaluate models trained on ToolRACERBench against internal benchmarks, as well as on function calling benchmarks such as $\tau^2$-bench, BFCLv3 and ACEBench to evaluate agentic accuracy and robustness. Models trained on ToolRACERBench improve end to end agentic accuracy across $\tau^2$-bench and ACEBench, demonstrating significant gains when mixed with in-domain dataset in small language models for agent capability tasks.

Multi-Objective Aligned Small Language Model Framework for SUD Patient Dialogue Generation

多目标对齐的小型语言模型框架用于物质使用障碍患者对话生成
Naduvilakandy, Thushara Manjari, Jang, Hyeju, Hasan, Mohammad Al
Abstract
Substance Use Disorder (SUD) counseling requires patient responses that reflect underlying cognitive states such as beliefs, coping strategies, and readiness for change. Although large language models (LLMs) can generate fluent text, they often fail to produce cognitively coherent and clinically realistic patient behavior, especially under ethical and data-scarce clinical settings. Moreover, deploying frontier-scale LLMs in healthcare applications presents practical challenges including high computational cost, latency, privacy concerns, and limited deployability in resource-constrained environments, motivating the need for cognitively aligned small language models (SLMs). We propose a cognitively grounded framework for SUD patient dialogue generation that explicitly models and aligns latent cognitive components with patient histories and counselor questions. Our pipeline consists of two stages: cognitive component detection and cognitive component-aligned dialogue generation. To enable effective learning with smaller models, we combine knowledge distillation from high-capacity teacher models, preference optimization from human-annotations, and attention-guided reward shaping. Extensive evaluations using automatic scores like BERTScore, ROUGE, METEOR and BLEU, and LLM-as-judge hit-metrics against both human and teacher-model references show that cognitively informed fine-tuning substantially improves cognitive realization and alignment over a generic instruction-tuned baselines and mental health domain specific SLMs, with particularly strong gains for open-ended cognitive components.

Dialect-Robust Speech Language Models with Synthetic Pseudo-Dialect Augmentation

具有合成伪方言增强的方言鲁棒语音语言模型
Mitsumori, Shunsuke, Mizumoto, Tomoya, Fujita, Yusuke
Abstract
Speech Language Model (SLM) performance often degrades on dialects due to data scarcity. Conventional text-to-speech (TTS) augmentation struggles to cover diverse dialects as it requires a certain amount of real dialect speech. We propose synthesizing pseudo-dialect speech by converting LLM-generated dialect text via a standard-language TTS model, requiring zero real dialect speech. Additionally, we introduce intermediate standard-text prediction during training, acting as semantic normalization for downstream tasks. We evaluate dialect understanding via dialect-to-English speech translation across Japanese, German, and Chinese dialects. Compared to synthetic standard speech baselines, pseudo-dialect augmentation improves scores for Japanese (from 25.38 to 26.24) and German (from 31.57 to 32.47). Furthermore, the intermediate standard-text prediction effectively bridges the semantic gap, boosting performance to 28.26 for Japanese and from 11.67 to 16.37 for Chinese.

语音语言模型(SLM)的性能在方言上往往会因数据稀缺而下降。传统的文本到语音(TTS)增强在覆盖多样化方言方面面临挑战,因为它需要一定数量的真实方言语音。我们提出通过标准语言TTS模型将大型语言模型(LLM)生成的方言文本转换为合成伪方言语音,从而无需真实方言语音。此外,我们在训练过程中引入中间标准文本预测,作为下游任务的语义规范化。我们通过日语、德语和汉语方言的方言到英语语音翻译评估方言理解能力。与合成标准语音基线相比,伪方言增强提高了日语(从25.38提升至26.24)和德语(从31.57提升至32.47)的得分。此外,中间标准文本预测有效地弥补了语义差距,使日语的性能提升至28.26,汉语从11.67提升至16.37。这些结果表明,我们的方法可以扩展到多种语言,而无需针对每种方言的语音资源。

OnlineQAT: On-Policy Distillation for Ultra-Low-Bit Large Language Models

在线量化感知训练:用于超低比特大语言模型的在线蒸馏
Wang, Wenjun, Li, Heng, Gu, Yanggan, Yang, Hongxia
Abstract
Quantization-aware training (QAT) can recover much of the accuracy lost when large language models are compressed below four bits. Existing re- covery stages, however, are commonly optimized on fixed completions or teacher-generated answers, whereas the deployed quantized model condi- tions on prefixes generated by itself. Quantization errors can therefore move the model into states that are absent from offline recovery data. We introduce OnlineQAT, a two-stage framework that first obtains a usable low-bit initialization through block-wise QAT and then performs on-policy distillation (OPD) on student-generated responses. At each visited pre- fix, a frozen full-precision teacher provides a sampled reverse-KL training signal. On Qwen3-1.7B, OnlineQAT obtains the best average among the compared quantized methods: 57.28 at W3A16 and 32.52 at W2A16, im- proving over ReasoningQAT by 2.90 and 0.44 points, respectively. The results suggest that student-visited states provide a useful recovery signal beyond fixed-completion training, particularly at three bits.

量化感知训练(QAT)能够恢复在将大语言模型压缩到四比特以下时损失的大部分准确性。然而,现有的恢复阶段通常是在固定的完成或教师生成的答案上进行优化,而部署的量化模型则依赖于自身生成的前缀。因此,量化误差可能使模型进入离线恢复数据中不存在的状态。我们提出了OnlineQAT,一个两阶段框架,首先通过块级QAT获得可用的低比特初始化,然后对学生生成的响应进行在线策略蒸馏(OPD)。在每个访问的前缀上,一个冻结的全精度教师提供一个采样的反向KL训练信号。在Qwen3-1.7B上,OnlineQAT在比较的量化方法中获得了最佳平均值:在W3A16上为57.28,在W2A16上为32.52,分别比ReasoningQAT提高了2.90和0.44点。结果表明,学生访问的状态提供了超越固定完成训练的有用恢复信号,特别是在三比特的情况下。

Expert Coupling in MoE Pretraining: Reducing All-to-All Overhead with Correlated Placement and Token Shuffling

MoE预训练中的专家耦合:通过相关放置和令牌洗牌减少全到全的开销
Gulhane, Radha, Anthony, Quentin, Millidge, Beren
Abstract
Mixture-of-Experts (MoE) layers replace the feed-forward block of a Transformer with E expert networks, and each token is routed to k of these experts. Under expert parallelism (EP) the experts are distributed across GPUs, and every MoE layer runs all-to-all collectives in the forward and backward passes to dispatch tokens to their experts and then combine the results. On a cluster with 8 AMD Instinct MI300X GPUs per node, these collectives can take 45% of the training step at EP32 with top-2 routing and 60% with top-6 routing. We find that early in pretraining routers have already learned to assign tokens to experts in correlated patterns, both within a layer and across layers. At top-2, 0.8% of the expert pairs in a layer are selected together by 42% of tokens, and the experts a token selects at one layer predict the experts it selects at the next layer. We use these correlations to keep more token--expert assignments on the token's own GPU, which reduces communication across GPUs and across nodes. Correlated expert placement puts experts that are often selected together on the same GPU. Combined with a dispatcher that sends each token to each GPU once, it removes up to 58% of dispatched rows. Token shuffling applies when sequence parallelism shards tokens across the EP group. It moves each token to the GPU predicted to hold its next-layer experts during the reduce-scatter that follows attention. On one node this raises the share of token--expert assignments served on the token's GPU from 12.5% to 59%. In Megatron-LM, across EP degrees from 8 to 64 with top-2 and top-6 routing, the two methods reduce all-to-all time by 1.16-2.63X and end-to-end step time by up to 1.41X. Neither method changes the models' underlying routing decisions or expert parameters.

The Persona Hierarchy Model: Understanding Contextual Generalization in Fine-Tuning LLMs

角色层次模型:理解大规模语言模型微调中的上下文泛化
Zhao, Jiachen, Wu, Zhengxuan, Bau, David, Shi, Weiyan
Abstract
Language models are routinely fine-tuned under a fixed context, such as a generic system prompt, persona or domain-specific instruction, yet the learned behavior sometimes stays confined to that context and sometimes broadly generalizes to unseen contexts. We propose the Persona Hierarchy Model to explain this: a shared default persona influences behavior across contexts. Under this model, fine-tuning that modifies the shared persona promotes broader transfer, whereas changes to local personas remain more context-specific. Across 120 fine-tuned models spanning four behaviors and 15 training contexts, generalization narrowness positively correlates with the similarity between the training context's persona and the default persona (Pearson's r = 0.72 for Qwen3-4B). Prior fine-tuning under the default context can broaden generalization in subsequent training under other contexts. Aligning contextual responses with default-persona responses produces stronger effects. Finally, we propose persona-preserving regularization (PPR) to confine undesired contextual generalization. In RL, PPR cuts reward hacking from 42-55% to at most 0.2% under every evaluated prompt while retaining accuracy gains. These results support the Persona Hierarchy Model as an explanation for contextual generalization and can motivate future controls on unintended generalization for better alignment of LLMs.

语言模型通常在固定上下文下进行微调,例如通用系统提示、角色或特定领域的指令。然而,学习到的行为有时局限于该上下文,有时则能广泛泛化到未见过的上下文。我们提出了角色层次模型来解释这一现象:一个共享的默认角色影响着不同上下文中的行为。在该模型下,修改共享角色的微调促进了更广泛的迁移,而对局部角色的改变则更具上下文特异性。在涵盖四种行为和15个训练上下文的120个微调模型中,泛化的狭窄程度与训练上下文的角色与默认角色之间的相似性呈正相关(对于 Qwen3-4B,Pearson's r = 0.72)。在默认上下文下的先前微调可以在后续其他上下文的训练中拓宽泛化。将上下文响应与默认角色响应对齐会产生更强的效果。最后,我们提出了角色保持正则化(PPR)来限制不必要的上下文泛化。在强化学习中,PPR将奖励黑客行为从42-55%降低到最多0.2%,同时保持准确性提升。这些结果支持角色层次模型作为上下文泛化的解释,并可以激励未来对意外泛化的控制,以更好地对齐大规模语言模型。

ARCS: Towards Precise Text-to-SQL via Structured Disambiguation

ARCS:通过结构化消歧迈向精确的文本到SQL转换
Hu, Yihao, Feng, Yanlin, Otani, Naoki, Bhutani, Nikita
Abstract
As text-to-SQL systems move beyond demonstrations toward real-world deployment, ambiguity in user questions becomes a primary source of errors. Such ambiguities are often subtle, domain- or data-specific, and can silently cause system outputs to deviate from the user's true intent. Ambiguity is traditionally addressed through conversational clarification, which is often inefficient, cognitively demanding, and poorly aligned with real-world user workflows. We propose structured disambiguation, a new paradigm in which ambiguity is resolved through explicit, constrained interactions rather than free-form dialogue. We construct ARCS (Ambiguity Resolution Corpus for SQL), the first text-to-SQL benchmark featuring naturally occurring, unconstrained ambiguities over real-world databases, with complete annotations of all valid ambiguity points, interpretations, and SQL queries. Experimental results show that text-to-SQL remains challenging in the presence of ambiguity: gpt-6-sol achieves only 51% end-to-end execution accuracy, and no open-source model exceeds 27%.

Arctic Questions, Missing Answers: A Dataset and Benchmark for LLM Abstention in Arctic Science

北极问题,缺失答案:一个关于北极科学中大型语言模型弃权的数据集和基准
Wilcox, Benjamin, Gao, Dawei, Kathiravelu, Pradeeban, Causey, Douglas, Sha, Kewei, Feng, Yunhe
Abstract
Large language models (LLMs) should abstain from scientific multiple-choice questions when no option is valid, but frequent abstention alone does not demonstrate sensitivity to answer availability. We introduce ArcticQA, a dataset of 194 questions derived from primary Arctic research, with automated checks of answer support and distractor contradiction against source evidence. We further develop ArcticAbstain, a paired benchmark comparing answer-present and answer-absent conditions, with the correct answer replaced by a distractor in the latter and an explicit abstention option in both. We evaluate eight models from the Gemini, Claude, and ChatGPT families at high reasoning effort, with three trials per condition, yielding 9,312 recorded responses. Answer-present abstention rates range from 0.0% to 63.0%, whereas replacing the correct answer increases abstention by 5.05 percentage points on average. These findings highlight substantial baseline differences and the need to evaluate abstention frequency and responsiveness jointly. The dataset and benchmark are available at https://github.com/BenWilcox8/arctic-qa.

Right Number, Wrong State? Measuring Cross-Jurisdiction Substitution in LLM Recall of State Policy

正确的数字,错误的州?测量大型语言模型在州政策回忆中的跨管辖区替代
Feng, Jiayu
Abstract
When an LLM answers a state-specific policy question wrongly, it may be hallucinating, or it may be returning a real value that holds in another state. We test this with a minimal-set design: the question wording is fixed and only the jurisdiction varies, across the 50 U.S. states and the District of Columbia (51 jurisdictions) and three exactly defined Medicaid income-eligibility quantities. Gold values come from an official data book and agree with an independent source in 101 of 102 checked cells. Under a pre-registered protocol, Claude Sonnet 5.5 and GPT-5.6 Sol reproducibly give another state's current value, identical across two independent repeats, for 10 and 25 of 153 items. Attribution is fragile, however. Crediting any wrong answer that equals another state's value yields 3-5x more reproducible substitutions than checking every number in the asked state's own records, because many apparent cross-state answers are the asked state's own values under another convention or from an earlier year. Claims about cross-jurisdiction error need a complete same-state reference set. We will release the protocol, gold table, and all model outputs.

BanglaRhet: Benchmarking Classical and Transformer Models for Rhetorical and Persuasion Detection in Bangla Political Speech

BanglaRhet:经典模型与变换器模型在孟加拉政治演讲中修辞与说服检测的基准研究
Sen, Rohit Kumar, Chowdhury, Anik
Abstract
Political discourse often uses rhetorical and persuasive language to frame narratives, influence public opinion, and mobilize audiences. While Bangla natural language processing has made progress in sentiment analysis and opinion mining, systematic benchmarking of transformer models for fine-grained rhetorical and persuasion technique detection in Bangla political speech remains largely underexplored. This paper presents a benchmark study of transformer-based models for detecting rhetorical form and persuasive intent in Bangla political discourse. Using BanglaRhet, a manually annotated corpus of 30,289 Bangla political speech segments collected from publicly available political news sources, we formulate two supervised single-label classification tasks: rhetorical technique detection (contrast, repetition, exaggeration, metaphor, rhetorical questions) and persuasion technique detection (blame assignment, call to action, unity call, moral, emotional, and logical appeals). We evaluate four transformer-based models, BanglaBERT, BanglaBERT-Base, SahajBERT, and XLM-RoBERTa-Base, against classical TF-IDF baselines. BanglaBERT achieves the highest performance, with 65.40% macro-F1 for rhetorical technique detection and 66.46% for persuasion technique detection, outperforming the best tuned classical baseline by 19.2 and 13.8 macro-F1 points, respectively. Class-level analysis indicates that errors are mainly associated with semantic overlap among labels, figurative language, and class imbalance. The results provide initial benchmark baselines for Bangla rhetorical and persuasion-aware political discourse analysis and highlight the need for context-aware and multi-label modeling.

Goldsmith: Gold-Loss-Guided Definition Optimization with an Agentic Annotation Harness

Goldsmith:基于黄金损失引导的定义优化与自主标注框架
Li, Yihan, Zhang, Hanyi, Jiang, Xiaoxi, Guo, Man
Abstract
Many annotation projects begin before experts have a stable guideline or enough labels to train a task-specific model. We present Goldsmith, an agentic pipeline that turns a small gold set---expert-annotated calibration examples representing the intended task boundaries---into a reusable structured annotation definition. Goldsmith treats this definition as a trainable textual object. Candidate definitions are run on the same gold examples and scored with an executable structured loss, while the output schema, formatting, retrieval, repair, judging, and human review remain in an external harness. A large language model (LLM) editor converts the highest-loss failures into textual-gradient revisions, which are accepted only when the measured loss decreases. In prompt-optimization comparisons, Goldsmith improves over direct rewriting, OPRO, APE, and PromptBreeder under matched evaluation protocols. The resulting definition also improves downstream annotation when combined with retrieval, score-based routing, and human review across typed span, pair-level relation, and fixed-trigger event-argument tasks. These results show that scarce expert supervision can support both task-definition learning and scalable annotation.

Abstract
There are more than 2,000 listed companies on the UK's London Stock Exchange, divided into 11 sectors who are required to communicate their financial results at least twice in a single financial year. UK annual reports are very lengthy documents with around 80 pages on average. In this study, we aim to benchmark a variety of summarisation methods on a set of different pre-trained transformers with different extraction techniques. In addition, we considered multiple evaluation metrics in order to investigate their differing behaviour and applicability on a dataset from the Financial Narrative Summarisation (FNS 2020) shared task, which is composed of annual reports published by firms listed on the London Stock Exchange and their corresponding summaries. We hypothesise that some evaluation metrics do not reflect true summarisation ability and propose a novel BRUGEscore metric, as the harmonic mean of ROUGE-2 and BERTscore. Finally, we perform a statistical significance test on our results to verify whether they are statistically robust, alongside an adversarial analysis task with three different corruption methods.

RELATE: An Evaluation Framework for measuring Relational Orientation of Large Language Models

RELATE:用于测量大型语言模型关系导向的评估框架
Shukla, Shivam, Kim, Jihye, Gaur, Shubham, Roshanaei, Mahnaz, El-Nasr, Magy Seif
Abstract
Large language models (LLMs) are increasingly used for emotional support, raising concern that sustained use may draw users away from their real-world relationships. Yet existing evaluations primarily focus on the safety, empathy, or helpfulness of responses, leaving under-examined a relational question: where does the model orient the user for continued support? To address this question, we introduce relational orientation, a property operationalized through two non-exclusive dimensions: inward-facing (IF) language, which positions the AI as the user's ongoing source of support, and outward-scaffolding (OS) language, which encourages real-world human connection. Grounded in psychological and sociological literature, we formalize a taxonomy of relational orientation and present RELATE, a persona-conditioned framework for measuring inward-facing and outward-scaffolding language at the sentence level in multi-turn dialogues. RELATE pairs 76 help-seeking situations adapted from naturally occurring questions with three simulated user styles, providing 228 evaluation stimuli. In our experiments, we evaluate seven LLMs using dialogues with six assistant turns each, yielding 1,596 dialogues and 69,194 assistant sentences. We assess these sentences using a primary rubric-based LLM judge and apply a secondary judge to a subset. Under automated evaluation, we find that the proportion of sentences labeled as IF is higher at the sixth assistant turn than at the first, while the proportion labeled as OS is substantially lower for hesitant, indirect simulated users than for explicit, reassurance-seeking users. RELATE provides a reproducible framework and a sentence-level signal for auditing and steering the relational orientation of supportive LLMs.

How Do LLMs Change Predictions Under Negation?

大型语言模型如何在否定下改变预测?
Yoon, Jongwook, Lim, Jongwon, Lim, Sungjib, Cho, Woojin, Jo, Yohan
Abstract
Negation is an essential feature of human language, yet large language models (LLMs) remain unreliable in processing it. We evaluate recent open-source and closed-source LLMs on our negation benchmark and find that, in 37-71% of cases, they repeat the same answer under negation (e.g., "Madrid" for "What is not the capital of Spain?"). To understand and address this brittleness, we mechanistically examine how models operate under negation. Our main finding is that specialized attention heads and MLP neurons jointly implement negation by (1) suppressing retrieval of the original answer (e.g., "Madrid") while (2) promoting a favored candidate within the answer category (e.g., "Paris"). This contrasts with accounts of human negation processing, in which information about the original answer helps to determine what should be excluded. Furthermore, we find that this difference from human processing is a key source of negation failures: the model's mechanism relies on suppressing the original answer rather than using it to determine what to exclude, so the model can repeat the original answer when suppression is too weak or when a bias toward particular answers prevents it from selecting an alternative. To address this weakness in the model's negation mechanism, we propose a training objective that requires larger shifts in answer preference for more confident original predictions, and show that it reduces negation failures with less degradation of general capabilities than standard fine-tuning baselines. Together, our results demonstrate how mechanistic analysis can reveal why a linguistic capability fails and guide training that targets the underlying limitation.

否定是人类语言的一个重要特征,但大型语言模型(LLMs)在处理否定时仍然不可靠。我们在否定基准测试中评估了最近的开源和闭源LLMs,发现它们在37-71%的情况下在否定下重复相同的答案(例如,对于“西班牙的首都不是哪里?”的问题,它们回答“马德里”)。为了理解和解决这种脆弱性,我们机制性地考察了模型在否定下的运作方式。我们的主要发现是,专门的注意力头和多层感知器(MLP)神经元共同通过(1)抑制原始答案的检索(例如“马德里”),同时(2)促进答案类别内的一个优选候选(例如“巴黎”)来实现否定。这与人类否定处理的解释形成对比,在人类处理过程中,关于原始答案的信息有助于确定应排除的内容。此外,我们发现这种与人类处理的差异是否定失败的一个关键来源:模型的机制依赖于抑制原始答案,而不是利用它来确定应排除的内容,因此当抑制过弱或对特定答案的偏见阻止其选择替代答案时,模型可能会重复原始答案。为了应对模型否定机制中的这一弱点,我们提出了一种训练目标,要求对更自信的原始预测进行更大的答案偏好转变,并显示出它在减少否定失败的同时,较标准微调基线对一般能力的降级更小。总之,我们的结果展示了机制分析如何揭示语言能力失败的原因,并指导针对基础限制的训练。

Which Language Should a Skeleton Speak? Language Choices in Multilingual Reasoning

骨架应使用哪种语言?多语言推理中的语言选择
Lim, HyeonSeok, Song, SeungWoo, Won, Inho, Song, Hoyun, Kim, Jihyo, Lim, KyungTae
Abstract
Skeleton-based reasoning prompting is a promising training-free approach for structuring LLM reasoning, but prior work largely assumes an English-centric setting. We propose the Language-Aware Skeleton Exploration Framework (LASEF) to study skeleton-language choice in multilingual mathematical reasoning. Across math benchmarks, model scales, and languages, we show that English skeletons yield a small positive tendency on average, most visible for smaller models and low-resource languages. However, few language-level gains remain significant after correction, and English is not universally optimal. Combining greedy decoding, multi-rollout evaluation, translation ablation, and cross-benchmark validation, we further find three patterns of skeleton-language effects: directionally consistent, evaluation- and benchmark-dependent, and asymmetric negative. These effects cannot be fully explained by generation quality alone. Overall, skeleton language is a context-dependent design variable that requires multi-level exploration.

在线策略蒸馏教授新技能但不传授新知识
Tang, Yixuan, Yang, Yi
Abstract
On-policy distillation (OPD) strengthens language-model reasoning, yet whether students acquire new factual knowledge or compositional skill for multi-step reasoning remains unknown. We separate these capabilities using a controlled synthetic framework that measures the student's initial capabilities and independently controls the teacher's additional facts, compositional skill, or both. Across four models from three families, reverse-KL OPD reliably transfers compositional skill across unseen reasoning structures, but transfers minimal factual knowledge. Decoupling the distillation recipe reveals the source of this asymmetry: replacing reverse KL with forward KL restores factual transfer, whereas student rollouts specifically improve the execution of multi-step reasoning. Experiments on recent factual QA and competition mathematics show a similar asymmetry under reverse-KL OPD, yielding notable reasoning gains without factual memory expansion. Together, these results demonstrate that on-policy distillation does not expand a model's parametric knowledge, but instead teaches it to organize and compose the knowledge it already possesses.

在线策略蒸馏(On-policy distillation, OPD)增强了语言模型的推理能力,但学生是否获得了新的事实知识或多步骤推理的组合技能仍然未知。我们使用一个受控的合成框架来区分这些能力,该框架测量学生的初始能力,并独立控制教师的额外事实、组合技能或两者。通过来自三个家族的四个模型,反向KL OPD可靠地在未见过的推理结构中转移组合技能,但对事实知识的转移非常有限。解耦蒸馏配方揭示了这种不对称的来源:用正向KL替换反向KL恢复了事实转移,而学生的执行过程特别改善了多步骤推理的执行。最近的事实问答和竞赛数学实验显示,在反向KL OPD下存在类似的不对称性,带来了显著的推理提升而没有事实记忆的扩展。综合来看,这些结果表明,在线策略蒸馏并没有扩展模型的参数知识,而是教会模型组织和组合其已有的知识。

Rubric Spans are Label Representations: Joint LLM Encoding for Short Answer Scoring

评分标准跨度是标签表示:用于短答案评分的联合大语言模型编码
Sun, Zhifan, Gombert, Sebastian, Zehner, Fabian, Camus, Leon, Cong, Longwei, Drachsler, Hendrik
Abstract
Automatic Short Answer Scoring (ASAS) requires models that can score student responses against question-specific criteria while remaining efficient and transferable across rubric sets. We propose RUSPAN, a rubric-conditioned ASAS framework that treats rubric descriptions as semantic label representations. RUSPAN serialises the question context, student answer, and all candidate rubric levels into a single sequence, then scores the levels listwise from the rubric-span and whole-sequence representations produced in a single LM pass. We further introduce RUSPAN-RIM, in which a Rubric-Independent Mask prevents rubric spans from attending to one another, making rubric representations depend only on the answer and question context and preventing overfitting to rubric patterns during training for zero-shot transfer. On six ASAS benchmarks spanning English, German, and Portuguese, RUSPAN improves mono-benchmark scoring over discriminative and generative baselines, while RIM with position reindexing delivers consistent and substantial gains on PT-ASAG, the held-out benchmark with the strongest combined language and rubric-structure shift.

自动短答案评分(ASAS)需要能够根据特定问题标准对学生回答进行评分的模型,同时在不同评分标准集之间保持高效性和可迁移性。我们提出了RUSPAN,一个基于评分标准的ASAS框架,将评分标准描述视为语义标签表示。RUSPAN将问题上下文、学生答案和所有候选评分标准级别序列化为一个单一序列,然后从评分标准跨度和在单次语言模型传递中生成的整体序列表示中对级别进行列表评分。我们进一步引入了RUSPAN-RIM,其中一个与评分标准无关的掩码防止评分标准跨度相互关注,使评分标准表示仅依赖于答案和问题上下文,并在训练过程中防止对评分标准模式的过拟合,以实现零-shot迁移。在涵盖英语、德语和葡萄牙语的六个ASAS基准测试中,RUSPAN在判别和生成基线之上提高了单一基准评分,而带有位置重新索引的RIM在PT-ASAG(具有最强语言和评分标准结构转变的保留基准)上提供了一致且显著的提升。

Alice: A Large-Scale German Benchmark for Rubric-Based Multi-Dimensional Automatic Short Answer Scoring

Alice:一个基于评分标准的大规模德语多维自动短答案评分基准
Sun, Zhifan, Gombert, Sebastian, Lossjew, Jannik, Wyrwich, Tobias, Czinczel, Berrit Katharina, Bednorz, David, Kubsch, Marcus, Neumann, Knut, Drachsler, Hendrik
Abstract
Automatic Short Answer Scoring (ASAS) is central to NLP for Education. However, openly available benchmarks remain scarce, and existing datasets largely address how well students answer a question directly rather than how well they master underlying concepts (knowledge elements) such as thermal energy or epistemic activities (skills) such as reasoning or claim. To address this gap, we introduce Alice, a large-scale, rubric-based German ASAS dataset that is pedagogically aligned and comprises three subtasks: (i) learning performance (Alice-LP), (ii) knowledge elements (Alice-KE), and (iii) skills (Alice-SK). We further formulate rubric-based ASAS as a rubric-retrieval task and benchmark the dataset with a range of language models, from encoder-only models to lightweight LLMs. We also benchmark the dataset with zero-shot prompting via LLMs and a standard classification baseline. The experiments show that LLMs, in particular, struggle to score knowledge elements and skills in the zero-shot setting. They also indicate that rubric text is often useful, especially for Alice-KE and Alice-SK, while on Alice-LP gains over sample-solution-focused inputs are more modest and vary by model and input format.

自动短答案评分(ASAS)在教育领域的自然语言处理(NLP)中占据核心地位。然而,公开可用的基准仍然稀缺,现有数据集主要关注学生直接回答问题的能力,而非他们对基础概念(知识元素)如热能或认知活动(技能)如推理或主张的掌握程度。为了解决这一问题,我们推出了Alice,一个大规模的基于评分标准的德语ASAS数据集,该数据集在教学上具有一致性,并包含三个子任务:(i)学习表现(Alice-LP),(ii)知识元素(Alice-KE),以及(iii)技能(Alice-SK)。我们进一步将基于评分标准的ASAS形式化为一个评分标准检索任务,并使用一系列语言模型对数据集进行基准测试,从仅编码模型到轻量级大语言模型(LLMs)。我们还通过LLMs和标准分类基线对数据集进行零样本提示的基准测试。实验表明,LLMs,尤其是在零样本设置下,难以对知识元素和技能进行评分。结果还表明,评分标准文本通常是有用的,特别是在Alice-KE和Alice-SK上,而在Alice-LP上,相较于以样本解决方案为重点的输入,提升则更为温和,并且因模型和输入格式而异。

SAPD: Step-Aligned Privileged Distillation

SAPD:步对齐特权蒸馏
Wang, Tianle, Liu, Jiayu, Zhao, Ruizhi, Miao, Ning
Abstract
On-policy post-training can improve large language models by learning from their own trajectories, but requires costly rollout generation. We ask whether fixed demonstrations can support competitive off-policy learning through better supervision. Our premise is that their usefulness depends not only on the training trajectories, but also on whether supervision provides informative preferences among continuations and connects this guidance to the reasoning decision being learned. We introduce Step-Aligned Privileged Distillation (SAPD), a rollout-free self-distillation method that turns demonstrations into step-aligned distributional supervision. Its key insight is to use the known progression of a reference solution to associate each reasoning transition with targeted privileged guidance, rather than treating the solution as undifferentiated context. On mathematical reasoning benchmarks, SAPD outperforms supervised fine-tuning and label smoothing on average while remaining competitive with on-policy reinforcement learning and self-distillation. Analyses support both the value of context-dependent distributional guidance and the benefit of aligning privileged information with the current step. SAPD also largely preserves out-of-domain coding performance and achieves approximately 2x training-loop speedups over the on-policy baselines. These findings suggest that carefully constructed supervision can make fully off-policy post-training a competitive and computationally efficient alternative. Our code is available at https://github.com/Miaow-Lab/SAPD.

基于策略的后训练可以通过学习自身轨迹来改善大型语言模型,但需要昂贵的回滚生成。我们探讨固定演示是否能够通过更好的监督支持竞争性的离策略学习。我们的前提是,它们的有效性不仅依赖于训练轨迹,还依赖于监督是否提供了对后续步骤的有信息的偏好,并将这种指导与正在学习的推理决策联系起来。我们提出了步对齐特权蒸馏(SAPD),这是一种无回滚的自蒸馏方法,将演示转化为步对齐的分布式监督。其关键见解是利用参考解的已知进展,将每个推理过渡与目标特权指导关联,而不是将解视为未区分的上下文。在数学推理基准上,SAPD的表现平均优于监督微调和标签平滑,同时与基于策略的强化学习和自蒸馏保持竞争力。分析结果支持上下文相关的分布式指导的价值,以及将特权信息与当前步骤对齐的好处。SAPD在很大程度上保持了域外编码性能,并实现了约2倍的训练循环加速,相较于基于策略的基线。这些发现表明,精心构建的监督可以使完全离策略的后训练成为一种具有竞争力且计算高效的替代方案。我们的代码可在 https://github.com/Miaow-Lab/SAPD 获取。

InsClaimBench: Benchmarking Insurance Claim Adjudication Across the Decision Chain

InsClaimBench:跨决策链的保险索赔裁定基准测试
Zhang, Linqi, Qi, Chong, Cheng, Yan, Cao, Wanqing, Liu, Yu, Lin, Chenwei, Xu, Xian
Abstract
Recent advances in reasoning-oriented large language models (LLMs) have motivated increasing evaluation of their ability to perform professional decision tasks. Insurance claim adjudication is one such task, requiring models to connect case evidence, insurance rules, intermediate judgments, and payout calculations across a structured decision process. We introduce InsClaimBench, an end-to-end benchmark for evaluating insurance claim adjudication across the decision chain. Grounded in real claim materials and structured insurance rules, InsClaimBench contains 3,780 cases in 375 case families across auto, property, and health insurance, comprising 86,656 atomic rule judgments. It evaluates each claim from atomic rules through adjudication modules to payout decisions and amounts, with controlled factual variants testing whether required changes are correctly propagated across levels. Evaluation of six LLMs reveals a progressive loss of reliability along the decision chain. Payout-decision accuracy ranges from 74.23--80.19%, while joint decision--amount accuracy drops to 47.54--73.15%. Strong local performance also fails to ensure case-level correctness: atomic-rule accuracy reaches 95.48%, whereas rule-vector exact match peaks at only 36.90%, and the most frequent module errors are not necessarily those most associated with final-decision failure. Under factual changes, these inconsistencies further become propagation failures: module updates are less reliable than rule updates, correct local judgments can still yield incorrect payouts, and correct payouts can conceal intermediate errors. These results show that reliable claim adjudication requires consistent composition and propagation across the decision chain.

近期在面向推理的大型语言模型(LLMs)方面的进展,激励了对其执行专业决策任务能力的评估。保险索赔裁定就是其中一项任务,要求模型在结构化决策过程中连接案件证据、保险规则、中间判断和赔付计算。我们提出了InsClaimBench,这是一个用于评估跨决策链的保险索赔裁定的端到端基准测试。InsClaimBench基于真实的索赔材料和结构化的保险规则,包含了来自汽车、财产和健康保险的3,780个案例,分属于375个案例家庭,共计86,656个原子规则判断。它评估每个索赔,从原子规则到裁定模块,再到赔付决策和金额,并通过控制事实变体测试所需的变更是否在各个层级中正确传播。对六个LLM的评估显示,沿决策链的可靠性逐渐下降。赔付决策的准确率范围为74.23%到80.19%,而联合决策-金额的准确率下降至47.54%到73.15%。强大的局部性能并未确保案件级别的正确性:原子规则的准确率达到95.48%,而规则向量的精确匹配最高仅为36.90%,且最常见的模块错误并不一定与最终决策失败最相关。在事实变更下,这些不一致性进一步演变为传播失败:模块更新的可靠性低于规则更新,正确的局部判断仍可能导致错误的赔付,而正确的赔付可能掩盖中间错误。这些结果表明,可靠的索赔裁定需要在决策链中保持一致的组合和传播。

From Pareto to Preference: Personalized Test-Time Scaling via Amortized Agentic Policy Discovery

从帕累托到偏好:通过摊销的自主政策发现实现个性化的测试时间缩放
Wang, Xinglin, Liu, Zishen, Zheng, Tong, Feng, Shaoxiong, Yuan, Peiwen, Li, Yiwei, Shi, Jiayi, Zhang, Yueqi, Tan, Chuyi, Zhang, Ji, Pan, Boyuan, Li, Kan
Abstract
Test-time scaling (TTS) improves the reasoning capabilities of large language models by allocating additional inference computation. Existing approaches to improving TTS efficiency largely optimize accuracy against one resource dimension at a time, advancing either the accuracy--cost or accuracy--latency Pareto frontier. Yet user requirements are multidimensional: users may specify accuracy, latency, and inference-cost requirements jointly, and different requirements can favor different controllers. We formulate Personalized Test-Time Scaling as discovering executable controllers that maximize the joint satisfaction rate of user-specific requirements. To reduce the overhead of repeated policy discovery for new user profiles, we propose PersonTTS, an amortized agentic policy-discovery framework that reuses prior search experience through requirement-matched controller initialization and source-distilled procedural guidance, while retaining target-profile evaluation for every candidate. Experiments on AIME and HMMT show that PersonTTS substantially outperforms strong TTS baselines in joint requirement satisfaction on unseen user profiles and held-out problems. Under the same candidate-evaluation budget, cross-user experience reuse further improves policy quality while substantially reducing discovery-agent time and cost.

测试时间缩放(TTS)通过分配额外的推理计算来提高大型语言模型的推理能力。现有的提高TTS效率的方法主要是在一个资源维度上优化准确性,推动准确性-成本或准确性-延迟的帕累托前沿。然而,用户需求是多维的:用户可能同时指定准确性、延迟和推理成本的要求,而不同的要求可能更适合不同的控制器。我们将个性化测试时间缩放表述为发现可执行控制器,以最大化用户特定需求的联合满足率。为了减少对新用户配置进行重复政策发现的开销,我们提出了PersonTTS,这是一种摊销的自主政策发现框架,通过需求匹配的控制器初始化和源蒸馏的程序指导重用先前的搜索经验,同时对每个候选者保留目标配置的评估。在AIME和HMMT上的实验表明,PersonTTS在未见用户配置和保留问题上的联合需求满足方面显著优于强大的TTS基线。在相同的候选者评估预算下,跨用户经验重用进一步提高了政策质量,同时显著减少了发现代理的时间和成本。

SpikingVLA: Asynchronous Spiking Vision-Language-Action Models

SpikingVLA:异步脉冲视觉-语言-动作模型
Wang, Jingya, Zhang, Dehao, Wang, Shuai, Zhang, Malu, Yang, Yang, Li, Haizhou
Abstract
ANN-to-SNN conversion offers a practical route toward energy-efficient spiking Vision-Language-Action (VLA) models by bypassing the substantial cost of training large-scale SNNs from scratch. However, existing methods often require many timesteps to maintain competitive performance, resulting in substantial inference latency for real-time VLA deployment. To address this challenge, we introduce SpikingVLA, an ANN-to-SNN conversion framework that enables accurate and low-latency spiking VLA inference. Specifically, we propose a Dendritic Integrate-and-Fire (DIF) neuron that alleviates channel-wise activation outliers through dendritic mixing and adaptive somatic firing, enabling accurate ANN-to-SNN conversion with fewer timesteps. Building on DIF neurons, we further introduce an asynchronous execution mechanism that overlaps temporal computation across VLA components, reducing synchronization overhead and latency. Extensive experiments demonstrate that SpikingVLA achieves competitive navigation performance with substantially improved inference efficiency. Compared with existing spiking VLA methods, SpikingVLA improves SR and SPL by 11.9\% and 12.6\%, respectively, while reducing first-action latency by 11.2$\times$. These results establish SpikingVLA as a practical framework for deploying pretrained VLA models with high-performance and low-latency spiking inference.

Bridge Routing Heads: Where Multilingual Multi-hop Reasoning Lives in LLMs

桥接路由头:多语言多跳推理在大型语言模型中的存在
Kim, Seunghan, Choe, Minyeong, Kim, Hyunil, Cho, Haehyun
Abstract
Multilingual LLMs answer the same multi-hop reasoning question across languages, but we lack a mechanistic account of whether they share an internal circuit. We identify Bridge Routing Heads (BRH) in two large multilingual LLMs through a three-stage pipeline. The resulting language-specific head sets exhibit near-complete mutual exclusivity across the five languages, with a mean Jaccard similarity of only 0.017 for Llama 3.1 70B and 0.057 for Qwen 2.5 72B, revealing language-idiosyncratic circuits. Ablating general BRH increases two-hop Negative Log-Likelihood (NLL) by 39-89x the random-head baseline, providing direct causal evidence of their role. Amplifying these heads in a failing target-language pass rescues up to 51.7% of cross-lingual failures, with no training. The two models share this dual-circuit pattern but allocate heads differently: Llama concentrates chaining in a large general pool, while Qwen leans on larger language-specific pools. Together these results show that activation-level intervention alone can recover correct answers from cross-lingual reasoning failures.

Shaer: Controlled Arabic Poetry Generation with Meter Subform and Semantic Conditioning

Shaer:基于韵律子形式和语义条件的阿拉伯古典诗歌生成控制
Abbas, Ahmad, Fakih, Tamara, Fakih, Nour, Mohanna, Ammar
Abstract
Classical Arabic poetry generation requires simultaneously satisfying semantic, linguistic, and fine-grained prosodic constraints. Existing systems typically control broad poetic attributes but do not jointly model semantic intent, meter subform, and poem length. We present Shaer, a controllable Classical Arabic poetry generation framework jointly conditioned on natural-language descriptions, meter subforms, and target hemistich counts. To support this task, we construct an enriched corpus of 116,032 classical Arabic poems derived from Ashaar, containing normalized meter-subform labels and automatically generated, validated semantic descriptions. We then adapt Yehia-7B using QLoRA-based supervised fine-tuning with a completion-only objective. Our evaluation combines automatic assessment of base-meter conformity, requested-subform adherence, and length control with three LLM judges, blinded human evaluation, and memorization analysis. Shaer achieves 95.17% base-meter accuracy, 91.75% poem-level meter-subform accuracy, and 83.40% exact count accuracy. Relative to its untuned foundation model, these results represent gains of 68.68, 57.77, and 38.93 percentage points, respectively; Shaer also attains the highest base-meter accuracy among all evaluated systems. Multi-LLM evaluation and a blinded human assessment of top-ranked outputs further indicate competitive semantic and literary quality. Finally, analysis of all 3,481 test generations finds no exact copies from the training corpus or paired source poems. Code, models, and datasets are publicly available.

Decoupling Logic from Persona: Structural Immunity of Edge LLM Agents to Context Pollution

将逻辑与角色分离:边缘大语言模型代理对上下文污染的结构免疫性
Nakatsu, Masaaki, Wang, Reno
Abstract
Small language-model agents on edge devices must hold a persona and reason correctly at once, inside one context window that fills with conversational history and persona instructions. We study what happens to the logical part of such an agent when that history is long, misleading and persona-heavy (persona-logic interference), and present a Decoupling Architecture (AO-DA) that separates logical inference ("What") from persona expression ("How") into two inference paths on one INT4 base model with hot-swappable LoRA adapters. The logic path receives only the core turn and emits a verifiable structured state (Micro-State); the persona path renders it in character with the full history. In same-base-model ablations on an Apple M2 laptop (Llama-3.1-8B-Instruct and Gemma-3-4B-it, 4-bit; 480 runs over 4 pollution levels x 3 arms x 2 tasks x 2 personas x 5 seeds) we find: (i) the decoupled logic path is structurally invariant to pollution: its prompt stays at 180 (Llama) or 167 (Gemma) tokens while the mixed single-pass prompt grows from 242 to 1,203, and its outputs are byte-identical across levels (40/40); (ii) the mixed single pass degrades monotonically (composite logic score 0.669 to 0.150 on Llama, 0.487 to 0.150 on Gemma), mostly by failing to emit the required structured output (80-95% of runs on Llama, 100% on Gemma at the two highest levels); (iii) with the same pollution fed into the decoupled logic path, the dedicated-adapter, dedicated-format path is still more robust than the single pass on the 8B model (failure 0-20% vs 80-95%; paired $\Delta$ +0.30 to +0.50, Cliff's $\delta$ 0.50-0.85, Holm-adjusted $p \le 0.03$) but not on the 4B model, where both collapse. Separation costs one extra decode on a topic's first turn (28.2 s vs 18.2 s on Llama) and buys persona hot-swapping in 1.7 ms without re-running the logic path. Code, rubric, fixtures, adapters and logs are released.

Judging in Latent Space: Efficient Generative Reward Modeling via Semantics-Preserving Compression

在潜在空间中的判断:通过保持语义的压缩实现高效的生成奖励建模
Yuan, Mingqing, Liang, Xiaobo, Yang, Junwei, Chen, Ziwei, Zhang, Zeren, Wang, Hejin, Wang, Yubin, Li, Juntao
Abstract
Reward modeling often requires jointly representing and reasoning over multiple evaluation criteria, yet verbalizing this process token by token can incur substantial inference cost. Recent work on latent reasoning suggests that continuous states may support this computation more compactly. We introduce LatentGRM, a latent evaluation framework built on semantic chunking, compression, and reconstruction. By using the structure of rubric-guided evaluations to guide compression, LatentGRM learns compact continuous trajectories that support autonomous pairwise judgments without generating textual assessments. A separate interpreter reconstructs evaluation text from these trajectories, providing an offline view of the information retained under compression. Under matched training data and backbones, LatentGRM achieves competitive aggregate preference accuracy relative to explicit Supervised Fine-Tuning (SFT) judges at both 4B and 8B scales. Across four benchmark domains, LatentGRM-8B compresses evaluation trajectories by 8.9--9.2x and reduces total judge inference time by 6.1--7.0x at vote@5. Controlled rubric interventions show that criterion-dependent preference information is carried through the latent sequence. Together, these results demonstrate that continuous latent evaluation can substantially reduce inference cost while preserving competitive judgment quality.

奖励建模通常需要共同表示和推理多个评估标准,但逐字表达这一过程可能会产生巨大的推理成本。最近关于潜在推理的研究表明,连续状态可能更紧凑地支持这一计算。我们提出了LatentGRM,一个基于语义分块、压缩和重建的潜在评估框架。通过利用评分标准引导评估的结构来指导压缩,LatentGRM学习到紧凑的连续轨迹,支持自主的成对判断,而无需生成文本评估。一个独立的解释器从这些轨迹中重建评估文本,提供了在压缩下保留信息的离线视图。在匹配的训练数据和基础模型下,LatentGRM在4B和8B规模上相较于显式的监督微调(Supervised Fine-Tuning, SFT)评审者实现了竞争性的整体偏好准确性。在四个基准领域中,LatentGRM-8B将评估轨迹压缩了8.9--9.2倍,并在vote@5时将总评审推理时间减少了6.1--7.0倍。控制评分标准的干预显示,依赖标准的偏好信息通过潜在序列得以保留。这些结果共同表明,连续的潜在评估可以显著降低推理成本,同时保持竞争性的判断质量。

MIRROR: From Imitation to Internalization in LLM Personalization

MIRROR:从模仿到内化的LLM个性化
Lai, Huayi, Yang, Jicheng, Yi, Min, Meng, Chong
Abstract
The demand for personalized LLMs is shifting from style imitation toward content quality. We investigate whether self-distillation can bridge this gap in existing fine-tuning paradigm. To address this limitation, we introduce MIRROR(Meta- personalization by Internalizing Reference-Revealed On-policy Reflections), a novel self-distillation framework that shifts LLM personalization from imitation toward preference internalization. First, we replace reference-token imitation with reference-revealed on-policy self-distillation, aligning the model's next-token distributions along its own generation trajectories with those of its reference-conditioned self, thereby internalizing user preferences rather than reproducing reference wording.Second, we introduce MIRROR-F, a focal plug-in that augments on-policy distributional alignment with selective supervision over informative reference tokens, thereby strengthening content generation while preserving user-specific expression. Across three personalized generation benchmarks, two model scales, and complementary reference-based and LLM-based evaluations, MIRROR and MIRROR-F achieve leading overall personalization performance and superior text quality, while exhibiting less catastrophic forgetting than SFT-based baselines on three unseen personalized generation tasks.

个性化大型语言模型(LLMs)的需求正从风格模仿转向内容质量。我们研究自我蒸馏是否能够填补现有微调范式中的这一空白。为了解决这一局限性,我们提出了MIRROR(通过内化参考揭示的在线反思进行元个性化),这是一种新颖的自我蒸馏框架,将LLM个性化从模仿转向偏好内化。首先,我们用参考揭示的在线自我蒸馏替代参考标记的模仿,将模型的下一个标记分布与其参考条件自我生成轨迹对齐,从而内化用户偏好,而不是简单复制参考措辞。其次,我们引入了MIRROR-F,这是一种聚焦插件,通过对信息丰富的参考标记进行选择性监督,增强了在线分布对齐,从而在保持用户特定表达的同时加强内容生成。在三个个性化生成基准、两种模型规模以及互补的基于参考和基于LLM的评估中,MIRROR和MIRROR-F在整体个性化性能和文本质量方面表现出色,同时在三个未见的个性化生成任务中表现出比基于SFT的基线更少的灾难性遗忘。这些提升在不同模型规模和应用场景中是一致的,转化为LLM个性化任务的性能改善。

A Deafening Silence: Catastrophic Forgetting Lives in the Output Embeddings of Tokens the Data Never Speaks

震耳欲聋的沉默:灾难性遗忘存在于数据从未提及的标记输出嵌入中
Han, Jonghyun, Song, Younghoon, Park, Jongyoul
Abstract
Continual pre-training and fine-tuning in Large Language Models (LLMs) inevitably induce catastrophic forgetting, typically mitigated by replay using often-inaccessible original data. In this data-free regime, we analyze where forgetting occurs and why. Systematic parameter freezing across five settings up to 1.4B reveals that forgetting concentrates selectively in the output embeddings of tokens rarely seen in the new corpus, whereas the same sqrt(v-hat) band of the body is inert and new learning resides elsewhere. This localization is governed by the vocabulary deficiency of the corpus rather than the training mode, allowing pre-retraining risk ranking from token counts alone within a fixed base model. Mechanistically, absent tokens receive persistent one-sided softmax gradients that Adam's second-moment (sqrt(v-hat)) normalization amplifies into full-sized updates. We therefore propose an intervention: raising Adam's epsilon exclusively for the output projection during training. Across eight settings spanning 160M to 12B parameters and four model families, this removes 39.4% to 67.9% of forgetting across all seven stable configurations without degrading target learning or requiring per-model tuning. The defense combines additively or better with replay (79.8% on Qwen/Korean) and rescues released-head LoRA from a 23-fold forgetting surge. Because post-hoc editing of the drifted rows recovers under 5% of forgetting, the intervention must operate during training. Our findings indicate that a single-line optimizer adjustment may serve as the primary defense against catastrophic forgetting where the corpus starves the vocabulary.

在大型语言模型(LLMs)中,持续的预训练和微调不可避免地会导致灾难性遗忘,通常通过重放使用往往无法获取的原始数据来缓解。在这种无数据的情况下,我们分析了遗忘发生的地点及其原因。对五种设置(参数量高达14亿)进行系统的参数冻结,揭示了遗忘主要集中在新语料库中很少见的标记的输出嵌入中,而同一平方根(v-hat)带的主体则保持不变,新学习则发生在其他地方。这种局部化受语料库的词汇不足的支配,而非训练模式,使得在固定基础模型中仅凭标记计数就能进行预训练风险排序。从机制上讲,缺失的标记接收持续的单侧softmax梯度,而Adam的二阶矩(sqrt(v-hat))归一化将其放大为全尺寸更新。因此,我们提出了一种干预措施:在训练过程中仅提高Adam的epsilon以用于输出投影。在跨越160M到120B参数和四个模型家族的八种设置中,这种方法消除了39.4%到67.9%的遗忘,且在所有七种稳定配置中没有降低目标学习或需要对每个模型进行调优。该防御措施与重放(在Qwen/Korean上为79.8%)相加或更好,并使释放头LoRA免于23倍的遗忘激增。由于对漂移行的事后编辑恢复了不到5%的遗忘,因此该干预必须在训练期间进行。我们的发现表明,单行优化器调整可能成为应对语料库使词汇匮乏时灾难性遗忘的主要防御措施。

Training Advisors for LLM Agents from Task Outcomes

基于任务结果训练大型语言模型代理的顾问
Polezhaev, Sergei, Liskavets, Barys, Press, Ori, Golubev, Alexander
Abstract
Large language model agents tackle multi-step tasks by interleaving reasoning and tool calls with observations from the environment. Prior work has shown that natural-language feedback can help these agents revise their decisions during task execution. We introduce Caddie, a method for training critics to provide natural-language analysis and advice as agents work through a task. Unlike approaches that rely on step-level labels or reference critiques, Caddie learns from whether the agent ultimately succeeds after receiving the critic's feedback. We optimize the critic through reinforcement learning while keeping the base model frozen. Trained on multi-hop question answering with a single base model, our Qwen3-4B critic improves success rates across four base models of different scales and architectures, including three not used during critic training. On the MuSiQue benchmark, the trained critic improves Qwen3-4B's success rate by more than 25 percentage points, surpassing the performance of Kimi K3 without a critic. The same critic also yields gains on out-of-domain interactive benchmarks, including $\tau^3$ and DeepDive, with no additional training. Our results show that agents can decide when to seek help from a critic at inference time and that outcome-based critic training can produce guidance that transfers across base models and task domains.

大型语言模型代理通过将推理与工具调用与环境观察交替进行来处理多步骤任务。先前的研究表明,自然语言反馈可以帮助这些代理在任务执行过程中修正其决策。我们提出了Caddie,一种训练评论员在代理执行任务时提供自然语言分析和建议的方法。与依赖于步骤级标签或参考评论的方法不同,Caddie通过代理在收到评论员反馈后是否最终成功来学习。我们通过强化学习优化评论员,同时保持基础模型不变。在使用单一基础模型进行多跳问答的训练中,我们的Qwen3-4B评论员提高了四种不同规模和架构的基础模型的成功率,包括三种在评论员训练期间未使用的模型。在MuSiQue基准测试中,训练后的评论员使Qwen3-4B的成功率提高了超过25个百分点,超越了没有评论员的Kimi K3的表现。同一评论员在无额外训练的情况下也在域外交互基准测试中取得了提升,包括$ au^3$和DeepDive。我们的结果表明,代理可以在推理时决定何时寻求评论员的帮助,并且基于结果的评论员训练可以产生跨基础模型和任务领域的指导。

Itgan at NADI 2026 shared task: Parameter-Efficient Whisper Adaptation for Robust, Mixed-Dialect and Code-Switched Arabic ASR

Itgan在NADI 2026共享任务中的表现:针对稳健的混合方言和代码切换阿拉伯语自动语音识别的参数高效Whisper适应
Almajai, Ibrahim
Abstract
We describe the Itgan systems for the three ASR subtasks of NADI 2026, namely robust country-level ASR (1.1), mixed-dialect ASR (1.2), and Tunisian code-switched ASR (1.3). All three share one recipe, Whisper adapted with LoRA on consumer GPUs, and each was carried by a different addition to it. On 1.1, where the dialect label is given at test time, per-dialect specialists continued from a pooled adapter gave the largest gain, and the submitted system reached 57.1% country-average WER. A post-evaluation linear probe on frozen encoder features routes utterances without the label and recovers 44% of what oracle routing gives. On 1.2 the choice of base model mattered more than adapter capacity, and system combination helped only once we added a decorrelated member, reaching 46.7% WER. On 1.3 our system placed second at 14.49% WER with the lowest CER among the leading submissions, 5.38%. Its last 0.60 WER points came without further training, mostly from an exact weight-space average of independently trained runs, with ROVER voting adding the remainder. Every comparison carries a paired-bootstrap test, and we report eight directions that did not work.

EASE: Entropy-Adaptive Distribution Shaping for Evading AI-generated Text Detectors

EASE:用于规避AI生成文本检测器的熵自适应分布塑形
Zhou, Jicheng, Wong, Kahim, Wang, Jialong, Zhou, Jiantao
Abstract
AI-generated text (AIGT) detection can be sensitive to the decoding choices of the source large language model (LLM). We observe that perturbing next-token logits or adjusting sampling temperature can reduce detection performance, providing a clear signal of detector vulnerability to decoding-time distribution changes. Building on this observation, we propose EASE (Entropy-Adaptive Distribution Shaping for Evasion), a training-free and detector-agnostic framework for evading AIGT detectors. EASE computes predictive entropy directly from the source LLM's next-token distribution and uses it to adapt both logit perturbation and sampling temperature, without detector feedback or model fine-tuning. Experiments across three source LLMs and multiple detectors demonstrate consistent reductions in detection performance, with negligible degradation in text quality and negligible inference overhead.

AI生成文本(AIGT)检测对源大型语言模型(LLM)的解码选择可能非常敏感。我们观察到,扰动下一个标记的logits或调整采样温度可以降低检测性能,提供了检测器对解码时分布变化的脆弱性的明确信号。在此观察的基础上,我们提出了EASE(熵自适应分布塑形用于规避),这是一个无训练且不依赖于检测器的框架,用于规避AIGT检测器。EASE直接从源LLM的下一个标记分布计算预测熵,并利用该熵来调整logit扰动和采样温度,而无需检测器反馈或模型微调。在三个源LLM和多个检测器上的实验表明,检测性能一致降低,同时文本质量几乎没有下降,推理开销也微乎其微。

The Long Road to the Same Answer: Cognitive Bias Under Escalating Reasoning Budgets in Large Language Models

通往相同答案的漫长道路:大型语言模型中逐步推理预算下的认知偏差
Kraishan, Obada
Abstract
Reasoning models allocate extra computation at inference time and present their answers as the product of deliberate thought. If this deliberation works the way dual-process accounts of human cognition suggest, longer thinking should weaken the classic decision biases that fast, intuitive judgment produces. Using 30 vignettes covering six biases (anchoring, framing, loss aversion, escalation of commitment, availability, confirmation) from an established benchmark, we run a dose-response study across four model families, pairing each reasoning model with a matched non-reasoning sibling and requesting thinking ceilings of 0, 1,024, 4,096, and 8,192 tokens, for 12,350 API calls. Because a requested ceiling is not the same as realized deliberation, we use the reasoning tokens each call consumed as the dose. First, reasoning models are not less biased than their siblings; the point estimate leans the other way in every family, but the item-level pooled contrast is not reliable (Delta = +0.031, t(29) = 1.45, p = .157). Second, bias magnitude does not reliably fall as realized deliberation grows: no slope is significantly negative, and where anything moves it is the signed score drifting further from the human direction. Third, anchoring is the only bias in the human direction (d = 1.89). Four of the other five lean the opposite way in all seven models; with five items per bias, that reversal is reliable for framing and directional for escalation of commitment, confirmation, and loss aversion, while availability is absent. A one-line instruction to restate the anchor before answering lowered anchoring on all five anchoring items, which no amount of additional thinking did, although the effect does not reach significance (p = .057). The results argue against treating test-time reasoning as a rationality guarantee and for auditing deployed models bias by bias.

推理模型在推理时分配额外的计算资源,并将其答案呈现为深思熟虑的结果。如果这种深思熟虑的过程按照双过程理论的人类认知模型运作,那么更长的思考时间应该会削弱快速直觉判断所产生的经典决策偏差。我们使用涵盖六种偏差(锚定、框架效应、损失厌恶、承诺升级、可得性、确认偏误)的30个情境,进行了一项跨四个模型家族的剂量反应研究,将每个推理模型与一个匹配的非推理模型配对,并请求思考上限为0、1,024、4,096和8,192个标记,共进行了12,350次API调用。由于请求的上限与实际的深思熟虑并不相同,我们使用每次调用消耗的推理标记作为剂量。首先,推理模型并不比其兄弟模型更少偏见;在每个模型家族中,点估计都倾向于相反方向,但项目级的汇总对比并不可靠(Delta = +0.031, t(29) = 1.45, p = .157)。其次,偏差的幅度并不会随着实际的深思熟虑增加而可靠下降:没有斜率显著为负,而在任何变化中,签名分数都进一步偏离人类方向。第三,锚定是唯一一个朝向人类方向的偏差(d = 1.89)。其他五种偏差在所有七个模型中都倾向于相反方向;每种偏差有五个项目,这种反转在框架效应上是可靠的,并且在承诺升级、确认偏误和损失厌恶上是方向性的,而可得性则缺失。在回答之前重新表述锚定的单行指令降低了所有五个锚定项目的锚定效应,而额外的思考并未产生任何效果,尽管该效应未达到显著性水平(p = .057)。结果反驳了将测试时的推理视为理性保证的观点,并支持逐项审核已部署模型的偏差。

Cache the Encoder Within:Compact, Reusable Memory across LLM Queries

缓存编码器:跨大型语言模型查询的紧凑可重用内存
Liu, Hanzuo, Liu, Chunyu, Lin, Chaofan, Lamb, Alex, Gao, Mingyu
Abstract
Repeated queries over shared documents incur redundant encoding, while caching model states introduces persistent storage costs. Building on CoMem's intermediate-state interface, EncBank treats a pretrained LLM's lower layers as a reusable document encoder and compactly stores their outputs for an adapted upper-layer reader. A self-distilled suffix adapter is shared across storage precisions within each backbone, without quantization-specific retraining. Across five benchmark suites on three Qwen backbones spanning different sizes and full-attention and hybrid architectures, 4-bit storage keeps each reported benchmark aggregate within one score point of native-precision EncBank. In a fixed Qwen3-8B workload, it retains 28.1% of the native-precision persistent GPU store. Separate native-precision controls yield a 1.40x selected-pack prefill speedup over same-evidence, same-adapter text replay, at a 3.12-point RULER accuracy cost. A native-precision Qwen3.8-27B configuration also passes 70 of 89 Terminal-Bench 2.1 tasks. EncBank thus combines reusable computation with compact memory, while task fidelity and end-to-end benefits remain dependent on the workload, preparation costs, and reuse frequency.

ExperienceIndex: Artifact-Grounded Memory

经验指数:基于文献的记忆
Chen, Peter Baile, Yu, Geoffrey X., Liu, Xinming, Madden, Samuel, Roth, Dan, Andreas, Jacob, Downey, Doug, Cafarella, Michael
Abstract
Knowledge-intensive tasks require answering many questions by reasoning about a shared corpus of artifacts (e.g., court cases, or scientific literature). As humans interact with these corpora, they naturally accumulate experiential knowledge about artifacts, enabling them to quickly identify the complete set of relevant artifacts for each new task. However, existing AI agents lack appropriate memory solutions to build or reuse such artifact-grounded experience, leading to lower answer quality and higher online cost. Existing memory solutions extract and reuse information from prior task-solving traces, but they primarily focus on user preferences, factual attributes, or abstract reasoning patterns rather than persistent artifact-specific knowledge. We introduce ExperienceIndex, a novel experience layer for AI agents that captures and reuses knowledge about artifacts based on prior reasoning traces. ExperienceIndex stores two complementary forms of experience: (i) single-artifact experiences that summarize an artifact's contribution to prior tasks and (ii) artifact-pair experiences that encode structural relationships discovered during past reasoning. Integrated as lightweight middleware, ExperienceIndex uses an experience retrieval mechanism to guide agents toward the complete set of relevant artifacts for new tasks, improving both answer quality and efficiency. Across diverse corpora and agentic solutions with different search frameworks, ExperienceIndex delivers consistent gains, raising answer quality by up to 11.0 points and reducing online dollar cost by up to 50.5%. We further demonstrate two benefits: (i) cross-task generalization, where experiences accumulated from text-to-SQL tasks transfer to factoid QA tasks over the same artifact corpus, and (ii) teacher-student learning, where experiences from a stronger model enable a weaker model to reach comparable performance.

I would rather quit NLP than read another paper like this: The rise of antithesis in NLP papers

我宁愿退出自然语言处理(NLP)领域,也不想再读这样的论文:NLP 论文中对立面的兴起

Abstract
For better or worse, LLMs are by now used routinely for scientific writing.\footnote{This paper is no exception; we did use AI to assist with writing some of the sections (see Acknowledgments).} Many have noticed that recent models fill papers with unnecessary antithesis, stating over and over what the work does not do, in ways that do not contribute to its precision or quality of expression and annoy reviewers \emph{rather than impressing them}. We study the construction \emph{rather than} in ACL papers from 2019, ACL-style arXiv papers from 2026, and papers written by GPT models from the same titles and abstracts. Its rate in 2026 is seven times the 2019 rate, and higher still in the GPT papers. Two annotators, blind to the source, find almost no 2019 use \emph{annoying} and about one in ten 2026 uses; they seldom agree on which, yet about half of 2026 papers contain a use that annoys each of them. \emph{Annoying} uses present the rejected alternative less favorably than legitimate uses. Raters of preference data and open reward models favor the construction, and an instruction to be honest promotes it. We conjecture that it is a side effect of post-training on pairwise preferences, which credit a disavowal in a single response and cannot register its cost across a text.

Mechanics of Long-Context Hybrid Models Part 1.1: From Hybrid Attention to Hybrid Position

长上下文混合模型的力学 第1.1部分:从混合注意力到混合位置
Liu, Xiaoran, He, Ziwei, Qiu, Xipeng
Abstract
The architectural design of Large Language Models (LLMs) is shifting from traditional full-attention-only models to hybrid models, which combine different attention modules to improve long-context efficiency and performance in length extrapolation and context extension. To explain why hybrid models work and how to design them better, we propose Mechanics of Long-Context Hybrid Models. As Part 1.1 of this series, we begin with hybrids of full attention and either sliding-window attention (SWA) or gated variants of linear attention (LA), represented by GLA and GDN. We first observe a Seesaw Effect in Context Extension: LA hybrids benefit more from long-context continual pretraining, whereas SWA hybrids perform better under length extrapolation. We attribute this behavior to differences in the positional inductive biases induced by these attention mechanisms. We find that SWA hybrids suffer from a Short-Context Learning Trap, Short-Window Weariness, and Long-Window Laziness, and require extended windows to enhance performance in continual long-context pretraining. For LA hybrids, we summarize the Matthew Effect of Hybrid Position Extrapolation and propose Sliding-Window Linear Attention, achieving 16$\times$ training-free length extrapolation while maintaining 100\% accuracy on NIAH-SK1 in 64k context length.

LLM4Impact: Integrating Heterogeneous Information for Scientific Impact Prediction

LLM4Impact:整合异构信息以预测科学影响
Cao, Yong, Flicke, Markus, He, Haoyu, Renz, Katrin, Geiger, Andreas
Abstract
Predicting the future impact of a newly published paper is challenging because it must be inferred from heterogeneous evidence available at publication time. Existing approaches often rely on a single source of information or combine multiple sources without accounting for their different predictive roles. In this paper, we present LLM4Impact, an evidence-aware method for scientific impact prediction that learns to represent, integrate, and calibrate heterogeneous information. LLM4Impact combines semantic, graph, LLM, and temporal representations, and injects graph information into a frozen LLM through continuous prefix tokens. A context aware gating mechanism adaptively weights different evidence, while a separate calibration module accounts for domain and temporal variation in citation scales. We further construct a large-scale benchmark dataset with 2 million papers, leakage-safe point-in-time heterogeneous ego graphs, temporal splits, and both year-level and month-level citation targets. Experiments show that LLM4Impact consistently outperforms strong semantic, graph, and LLM based baselines, with a 10.13% reduction in year RMSE on the in distribution test set and a 6.87% reduction under out-of-domain distribution. Our results reveal that the value of such evidence is context dependent: different papers benefit from different sources, while domain and publication time affect how evidence translates into citations. This finding motivates adaptive evidence selection and context-conditioned calibration rather than simply richer representations. We will release our code, benchmark, and an interactive web demonstration upon publication.

InterView-C: A Synchronized Multimodal Corpus of VR Avatar-Mediated Survey Interviews

InterView-C:一个同步的虚拟现实化身中介调查访谈的多模态语料库
Schrottenbacher, Patrick, Hammerla, Leon, Kleine, Lydia, Stingl, Doris, Mehler, Alexander
Abstract
We present InterView-C, a German multimodal corpus of 27 survey interviews conducted entirely in virtual reality, with both interlocutors represented by avatars. The corpus aligns spoken interaction with synchronized behavioral data, including gaze, head and body movement, facial behavior, hand and finger tracking. Its reference transcripts and linguistic annotations provide a reliable interface between this multimodal spoken interaction and predominantly text-based NLP methods. This interface is important because automatically transcribing speech can distort linguistically relevant information, while downstream models trained on existing resources may additionally face transfer challenges when applied to transcribed spoken data. InterView-C therefore provides word-timed and manually post-edited verbatim transcripts for all 54 recordings, interview-item timings, questionnaire responses and negation cue and scope annotations for 1,422 sentences, 1,398 of them doubly annotated ({\alpha}=0.87 for cues; {\alpha}=0.81 for scopes). We demonstrate both challenges empirically: nine open-weight ASR systems disproportionately misrecognize short closed answers and number words, while negation models trained on existing corpora show lower and highly variable performance on our transcribed interviews than a model trained on the InterView-C annotations. InterView-C thus enables linguistic analyses of spoken interaction while retaining their alignment with rich multimodal behavior.

While canonical Rotary Position Embedding (RoPE) parameterizes the compact, elliptic branch of $\Sp(2,\R)$ via rotations, HySPE operationalizes its hyperbolic branch via a damped symmetric composition of dual shears, yielding a conformally symplectic contraction with two spectral decay rates per channel pair. To eliminate the exponential representation drift inherent to naive absolute factorizations, we diagonalize the operator in its invariant eigenbasis and introduce blockwise coordinate rebasing with adaptive centered execution. This guarantees length-independent numerical bounds while matching cached RoPE forward latency (7.21\,ms on an RTX 4090). On TinyShakespeare, HySPE-UltraLong maintains an invariant perplexity of 4.810 up to $16\times$ zero-shot extrapolation ($L=4096$), whereas RoPE degrades to 131.198. Scaled to a 51M-parameter subword Transformer on WikiText-103 ($L_{\text{train}}=512$), HySPE closely matches RoPE in-domain while robustly extrapolating to length 8192, reducing tail perplexity by 83.9\% over RoPE. While these controlled experiments establish HySPE's extrapolation robustness and numerical stability, evaluating its scaling behavior on large-scale foundation models remains an important direction for future investigation.

我们提出了超曲面辛位置编码(HySPE),将位置注意力建立在非紧凑辛变换的基础上。尽管经典的旋转位置嵌入(RoPE)通过旋转对$ ext{Sp}(2, ext{R})$的紧凑椭圆分支进行参数化,HySPE则通过双剪切的阻尼对称组合实现其超曲面分支,从而产生具有每对通道两个谱衰减率的共形辛收缩。为了消除天真的绝对因子化固有的指数表示漂移,我们在其不变特征基中对算子进行对角化,并引入基于块的坐标重基与自适应中心执行。这保证了长度无关的数值界限,同时与缓存的RoPE前向延迟(在RTX 4090上为7.21毫秒)相匹配。在TinyShakespeare上,HySPE-UltraLong在$16 imes$零-shot外推($L=4096$)时保持不变的困惑度为4.810,而RoPE降至131.198。在WikiText-103上,将其扩展到一个具有5100万个参数的子词Transformer($L_{ ext{train}}=512$),HySPE在领域内与RoPE紧密匹配,同时在长度8192上稳健外推,将尾部困惑度降低了83.9 ext{%}。虽然这些受控实验确立了HySPE的外推鲁棒性和数值稳定性,但评估其在大规模基础模型上的扩展行为仍然是未来研究的重要方向。

Beyond Outcome Rewards: Constructing and Assigning Retrieval Credit for Search Agents

超越结果奖励:为搜索代理构建和分配检索信用
Huang, Wenyu, Hou, Xinyu, Vougiouklis, Pavlos, Lai, Ruofei, Pan, Jeff Z.
Abstract
Search agents enable Large Language Models (LLMs) to iteratively retrieve and use information for complex multi-hop questions. Reinforcement Learning with Verifiable Rewards (RLVR) offers a promising approach for post-training such agents, but its reliance on sparse, outcome-based supervision can make credit assignment difficult and limit learning efficiency. In this paper, we systematically investigate how intermediate supervision can improve reinforcement learning for search agents. We study a range of reward-shaping and credit-assignment strategies that provide learning signals from intermediate retrieval steps. Building on these insights, we develop a training framework that combines intermediate signals with final outcome rewards to improve learning from multi-step search trajectories. Experiments across multiple benchmarks under matched training conditions demonstrate improvements in aggregate search-agent performance and show that both the choice of intermediate signal and where its credit is assigned affect training behaviour. These findings show that reward design and credit assignment are important design dimensions for training effective search agents.

搜索代理使大型语言模型(LLMs)能够迭代地检索和使用信息以解决复杂的多跳问题。可验证奖励的强化学习(RLVR)为后期训练这些代理提供了一种有前景的方法,但其对稀疏的、基于结果的监督的依赖可能使信用分配变得困难,并限制学习效率。本文系统地研究了中间监督如何改善搜索代理的强化学习。我们研究了一系列奖励塑造和信用分配策略,这些策略从中间检索步骤提供学习信号。在这些见解的基础上,我们开发了一个训练框架,将中间信号与最终结果奖励结合起来,以改善从多步骤搜索轨迹中学习的效果。在匹配训练条件下的多个基准测试中的实验表明,搜索代理的整体性能有所提升,并且中间信号的选择及其信用分配的位置都会影响训练行为。这些发现表明,奖励设计和信用分配是训练有效搜索代理的重要设计维度。

LLM Persuasion Is in the Eye of the Evaluation

大型语言模型的说服力在于评估的视角
Dementaviciute, Kamile, Vaitonyte, Julija, De Bie, Tijl
Abstract
Large language models (LLMs) have already been shown to match or exceed human experts in persuasion. While their persuasive capabilities hold promise for beneficial uses such as education and health communication, they can also be used to manipulate and misinform, making their evaluation a growing priority for developers and regulators. That evaluation, however, remains fragmented: studies differ in what they treat as persuasion, and broad claims often rest on narrow, situation-specific assessments. Automated methods, often modelled on human studies, offer a way to compare such assessments directly, as they can be run on the same models at scale and can include high-risk forms of persuasion that would be difficult or unethical to test on people. In this study, we adapt nine published automated methods to a shared setup, run them on the same fifteen LLMs, and ask whether their rankings agree and why. We find that the methods agree only weakly (mean Spearman $\rho = 0.25$). Our analyses point to two contributing factors. Models that refuse some tasks but not others, directly or indirectly, lower agreement by about a quarter, and these refusals fall mostly on manipulation tasks. General capability also plays a part: most rational persuasion (non-manipulative) methods track it, whereas most manipulation methods do not. Together, these findings suggest that agreement depends more on the task a method sets than on how it scores persuasion, although this pattern is only indicative given the eight methods available for analysis. More broadly, our results suggest that persuasion scores combine a model's ability to persuade with its willingness to do so. A single score is therefore informative about its own setting, but says little about a model's persuasiveness across tasks.

大型语言模型(LLMs)已经被证明在说服力方面能够与人类专家相匹敌或超越。尽管它们的说服能力在教育和健康传播等有益用途上展现出潜力,但也可能被用于操控和误导,这使得对其评估成为开发者和监管者日益重要的任务。然而,这种评估仍然是碎片化的:不同研究对说服力的定义各异,广泛的结论往往基于狭窄的、特定情境的评估。自动化方法,通常基于人类研究模型,提供了一种直接比较这些评估的方式,因为它们可以在相同的模型上大规模运行,并且可以包括那些在伦理上难以或不适合在人类身上测试的高风险说服形式。在本研究中,我们将九种已发布的自动化方法适配到一个共享的设置中,在同样的十五个LLMs上运行这些方法,并探讨它们的排名是否一致以及原因。我们发现,这些方法之间的共识仅为微弱(平均斯皮尔曼相关系数 $ ho = 0.25$)。我们的分析指出了两个影响因素。拒绝某些任务但不拒绝其他任务的模型,直接或间接地降低了一致性约四分之一,而这些拒绝主要集中在操控任务上。一般能力也起到了一定作用:大多数理性说服(非操控性)方法与其相关,而大多数操控方法则没有。综合来看,这些发现表明,一致性更多地依赖于方法设定的任务,而不是其如何评分说服力,尽管这一模式仅在可供分析的八种方法中具有指示性。更广泛地说,我们的结果表明,说服评分结合了模型的说服能力与其愿意进行说服的程度。因此,单一评分在其自身设置中是有信息量的,但对模型在不同任务中的说服力却提供了有限的信息。

Nobody Truly Agrees on Sentiment: Humans, Bespoke Tools, and LLMs Struggle with Social Media Texts

情感分析并无真正共识:人类、定制工具与大型语言模型在社交媒体文本中的挑战

Abstract
Social media is a rich source of real-time public sentiment, but widely used sentiment analysis tools are often applied without understanding their limitations. In this study, we evaluate the inter-rater reliability of three bespoke sentiment analysis tools (TextBlob, VADER, and Twitter-roBERTa-base) and three large language models (LLMs: Qwen3-32B, GPT-OSS-120B, Llama-4-Maverick-17B) against six human raters across 100 tweets. We measured agreement using two statistical measures: Cohen's kappa for pairwise comparisons and Fleiss' kappa for multiple raters. Even among the human raters, our results showed only fair agreement, highlighting the subjectivity of sentiment analysis. Higher agreement was observed under the binary sentiment classification (negative vs. non-negative and positive vs. non-positive) than under the three-class classification across both humans and automated tools. The Twitter-roBERTa-base model showed the strongest alignment with human ratings, outperforming both bespoke sentiment tools and LLMs, particularly in distinguishing negative versus non-negative sentiment. LLMs showed substantial agreement among themselves and moderate to substantial alignment with humans, performing better in positive vs. non-positive classifications. Our findings underscore that domain-specific fine-tuning remains crucial for reliable social media sentiment analysis, and human-centered evaluation remains essential for establishing gold-standard labels.

Learning to Act with Task Progress: Distilling Small Agents from Compact Teacher Supervision

基于任务进展学习行动:从紧凑教师监督中提炼小型智能体
Gan, Wenxi
Abstract
Learning from large-model demonstrations offers a way to train small agents that can complete recurring tasks without calling a large model at every step. A central design choice is what to retain from teacher trajectories that contain reasoning, actions, and information about task progress. We introduce Task-Progress Distillation (TPD), an offline approach that pairs each demonstrated action with a short label describing the current task stage. The student learns these compact targets and selects actions by jointly scoring admissible stage--action pairs, which a deterministic harness executes in the environment. On ALFWorld, a 1.7B student trained with 404 demonstrations achieves 72.4\% mean unseen task success with either TPD or action-only supervision, compared with 48.3\% for a reasoning-trained student using constrained action selection. Explicit stages provide an additional benefit at 200 demonstrations, improving success from 48.0\% to 67.7\% over action-only supervision. With more demonstrations, the action-only student closes the gap, and both approaches reach 76.9\% at 808 demonstrations. Shared-history analyses link part of TPD's local advantage to better decisions when moving between subgoals, particularly from object acquisition to processing. These results show that compact supervision can train effective small task agents, while explicit task progress provides additional guidance at an intermediate demonstration budget.

Document-Level Text Simplification in Estonian Using Large Language Models

使用大型语言模型进行爱沙尼亚语的文档级文本简化
Muru, Meeri-Ly, Barbu, Eduard
Abstract
Document-level text simplification involves transformations that go beyond sentence-internal edits, addressing discourse coherence, anaphora resolution, and cross-paragraph consistency. Despite advances in sentence-level simplification for high-resource languages, document-level simplification in morphologically rich, low-resource languages such as Estonian remains largely unexplored. This study presents a comprehensive evaluation of five state-of-the-art multilingual large language models (LLMs) for document-level simplification in Estonian. Three prompting strategies are examined: single-pass generation, pipeline-based modular agents, and guideline-augmented pipelines. The evaluation framework integrates automatic metrics assessing readability, semantic preservation, and discourse coherence, alongside a structured manual annotation protocol. The findings indicate that Gemini-2.0 and LLaMA-3.3 produce outputs with near-native fluency and strong meaning preservation, whereas other models display notable grammatical and semantic limitations. This work contributes novel document-level coherence metrics, evidence-based prompting strategies, and publicly available resources for reproducibility.

CoTrace: Data Recipes for Training Terminal Agents with Harness-Model Co-Evolution

CoTrace:用于训练终端智能体的带有工具模型协同进化的数据配方
Chen, Jixuan, Zhang, Jiaxin, Ye, Qinyuan, Pruksachatkun, Yada, Zhang, Haoxiang, Zhuo, Jingming, Zhang, Yifan, Dai, Yutong, Tan, Juntao, Peng, Xiangyu, Savarese, Silvio, Chen, Zeyuan, Qin, Lianhui, Wu, Chien-Sheng
Abstract
Terminal-agent capability depends jointly on model weights and the runtime harness that formats prompts, binds tools, and handles error recovery. Existing harness-model co-evolution approaches improve both components, yet often treat trajectories produced during harness search as an undifferentiated replay buffer. This practice overlooks that a trajectory's value for model training depends on the harness under which it was generated. To systematically analyze this interface, we establish an alternating co-evolution framework that decouples harness search and policy training through component-wise promotion decisions. Within this framework, we introduce CoTrace, a harness-aware data recipe that explicitly governs trajectory routing, provenance matching, and curriculum refresh. Under CoTrace, recurring execution failures guide harness synthesis, while policy training is strictly conditioned on verified rollouts matched to the adopted runtime for supervised fine-tuning (SFT) or fresh online interactions for reinforcement learning (RL). On the Tmax promotion split, CoTrace advances Qwen3.5-9B from 78 to 88 solved tasks under supervised fine-tuning while an online reinforcement variant reaches 90. Specifically, a compact harness-matched corpus produces steady model gains at substantially lower compute than much larger corpora pooled across sibling harnesses. Furthermore, evaluations on Terminal-Bench 2.1 and SWE-bench Lite show that out-of-distribution transfer depends fundamentally on harness compatibility, where maintaining consistency between training and evaluation runtimes prevents procedural execution breakdowns observed under foreign scaffolds.

终端智能体的能力依赖于模型权重和运行时工具的共同作用,后者负责格式化提示、绑定工具和处理错误恢复。现有的工具-模型协同进化方法改善了这两个组件,但通常将工具搜索过程中产生的轨迹视为一个未加区分的重放缓冲区。这种做法忽视了轨迹在模型训练中的价值取决于其生成时所用的工具。为了系统地分析这一接口,我们建立了一个交替协同进化框架,通过组件级的提升决策将工具搜索与策略训练解耦。在这个框架内,我们引入了CoTrace,这是一种关注工具的数据配方,明确管理轨迹路由、来源匹配和课程更新。在CoTrace下,重复的执行失败指导工具的合成,而策略训练严格依赖于与采用的运行时匹配的验证回放,以进行监督微调(SFT)或用于强化学习(RL)的新在线交互。在Tmax提升分割上,CoTrace使Qwen3.5-9B在监督微调下从78个解决任务提升至88个,而在线强化变体达到90个。具体而言,一个紧凑的工具匹配语料库在计算资源消耗上显著低于跨兄弟工具汇聚的大型语料库,且仍能产生稳定的模型增益。此外,在Terminal-Bench 2.1和SWE-bench Lite上的评估表明,分布外迁移根本上依赖于工具的兼容性,保持训练和评估运行时之间的一致性可以防止在外部框架下观察到的程序执行失败。

PHRBench: A Behavioral Evaluation of Post-Hallucination Reasoning in LLMs

PHRBench:大语言模型后幻觉推理的行为评估
Meng, Linghao, He, Feng, Yang, Xuan, Mao, Junyuan, Ren, Pinze, Mu, Deqing, Yang, Hesen, Li, Qiankun
Abstract
Hallucinated information can propagate through multi-stage LLM systems and become part of the context for subsequent reasoning. Existing studies of post-hallucination reasoning (PHR) mainly characterize changes in final outcomes and aggregate reasoning dynamics, leaving how models resolve hallucinated premises at the response level insufficiently understood. In this work, we introduce PHRBench, a controlled benchmark for behaviorally structured PHR across four domains and 18 large language models. PHRBench characterizes each reasoning trajectory independently of final-answer correctness through Hallucination Compliance, Hallucination Avoidance, and Heuristic Correction, and defines an insightful trajectory as successful correction that ultimately reaches the correct answer. Across 4820 controlled instances, we find that successful recovery remains relatively rare and is associated with more frequent belief updates along the reasoning trajectory. We further find that properties of the hallucinated prompt contain substantial predictive signal for successful recovery, with a lightweight predictor achieving an AUROC of 0.847. These findings provide a behavioral view of post-hallucination reasoning, characterizing how LLMs resolve erroneous context and when successful recovery is likely to occur.

Your Prompt Should Do More: Effects of Retrieval Instructions in Embedding Models

你的提示应该做得更多:检索指令在嵌入模型中的影响
Myntti, Amanda, Kanerva, Jenna, Laippala, Veronika, Ginter, Filip
Abstract
Prompted embedding models have recently received increasing attention, particularly for retrieval, where detailed retrieval instructions are provided as part of the retrieval prompt. Several new datasets and studies have examined this setting, showing that the current embedding models often struggle to follow such instructions reliably. In this paper, we study the mechanism of how instructions actually affect the representations of retrieval queries in asymmetric retrieval tasks. We show that models can fail to follow even simple task instructions when query-side distractors are included in the evaluation. We hypothesize that this behavior is driven by the training setup of current embedding models and their evaluation, and show that fine-tuning with added query-side distractors leads to substantial improvements, with minimal effect on other tasks.

EngramEdit: Decoupled Knowledge Updates in LLMs through Conditional Memory

EngramEdit:通过条件记忆实现大语言模型中的解耦知识更新
Cai, Hongru, Wei, Ran, Wang, Wenjie, Wu, Chengfa, Song, Ning, Li, Yongqi, Li, Wenjie
Abstract
Conditional memory architectures such as DeepSeek Engram use input n-grams to look up learned embeddings, expanding the capacity of large language models (LLMs) with limited additional computation. Beyond model scaling, this architecture has demonstrated the potential to decouple factual knowledge storage from general-purpose computation, offering a promising route to updating factual knowledge while keeping the Transformer backbone fixed. Realizing this potential is challenging because different expressions of a fact may activate different n-gram embeddings, while updating shared embeddings can unintentionally change the model's predictions about other facts. We propose EngramEdit for decoupled knowledge updates through conditional memory. EngramEdit first computes target memory representations that make the model predict the updated fact across multiple expressions. It then jointly updates the shared n-gram embeddings to match these targets across expressions and edits, penalizing updates to frequently reused embeddings more strongly to preserve unrelated knowledge. Experiments show that EngramEdit enables independent factual knowledge updates through conditional memory, achieving near-perfect editing success. Revised knowledge is usable across unseen expressions and in multi-hop reasoning, with nearly three times the strongest baseline's accuracy under chain-of-thought (CoT) prompting. Unrelated knowledge and general capabilities are largely preserved even as factual updates accumulate. These findings show that EngramEdit turns conditional memory into an editable knowledge interface, extending its role beyond model scaling to support decoupled knowledge updates.

条件记忆架构,如 DeepSeek Engram,利用输入 n-gram 查找学习到的嵌入,从而在有限的额外计算下扩展大型语言模型(LLMs)的容量。除了模型扩展外,该架构还展示了将事实知识存储与通用计算解耦的潜力,提供了一条有希望的途径来更新事实知识,同时保持 Transformer 主干不变。实现这一潜力具有挑战性,因为事实的不同表达可能激活不同的 n-gram 嵌入,而更新共享嵌入可能会无意中改变模型对其他事实的预测。我们提出了 EngramEdit,通过条件记忆实现解耦知识更新。EngramEdit 首先计算目标记忆表示,使模型能够在多种表达中预测更新后的事实。然后,它联合更新共享 n-gram 嵌入,以匹配这些目标在不同表达和编辑中的表现,并对频繁重用的嵌入施加更强的惩罚,以保留无关知识。实验表明,EngramEdit 通过条件记忆实现独立的事实知识更新,达到近乎完美的编辑成功率。修订后的知识可用于未见过的表达和多跳推理,在链式思维(CoT)提示下,其准确率几乎是最强基线的三倍。即使事实更新不断累积,无关知识和一般能力也在很大程度上得以保留。这些发现表明,EngramEdit 将条件记忆转变为可编辑的知识接口,扩展其角色,不仅限于模型扩展,还支持解耦知识更新。
