EFLUX: Elastic Multi-Robot Formation Navigation and Adaptation with Agentic LLMs
EFLUX:基于代理大型语言模型的弹性多机器人编队导航与适应
Abstract
Multi-robot teams operating in confined or cluttered environments must adapt both their formation geometry and group topology to navigate through complex obstacles. This adaptation requires two complementary behaviors: deformation, where the team continuously reshapes its geometry while remaining connected, and reconfiguration, where robots split into subgroups or merge back into a single formation. Existing methods often model these behaviors independently, connect them through handcrafted rules, or lack explicit geometric criteria for determining when each behavior should be invoked. However, challenging environments may require online changes in formation shape, connectivity, and effective team composition, making decoupled or rule-based approaches prone to suboptimal trajectories and deadlock. We propose EFLUX, a geometry-grounded LLM agentic framework for automatic and elastic multi-robot formation navigation. EFLUX extracts a structured scene representation and uses an LLM to reason jointly over both deformation actions, such as scaling and shearing, and reconfiguration actions, such as splitting and merging. These strategies are then translated into executable per-robot waypoints through a closed-loop generation, verification, and correction pipeline. Simulation and hardware experiments show that EFLUX enables safe, continuous, and elastic formation navigation in constrained environments, reducing deadlock and navigation failures compared with baselines while maintaining coherent multi-robot coordination.

在封闭或杂乱环境中操作的多机器人团队必须调整其编队几何形状和群体拓扑,以便穿越复杂障碍。这种适应需要两种互补行为:变形,即团队在保持连接的同时不断重塑其几何形状;重构,即机器人分成子组或重新合并为一个单一编队。现有方法通常独立建模这些行为,通过手工规则将其连接,或缺乏明确的几何标准来确定何时应调用每种行为。然而,具有挑战性的环境可能需要在线改变编队形状、连接性和有效团队组成,使得解耦或基于规则的方法容易导致次优轨迹和死锁。我们提出了EFLUX,一个基于几何的LLM代理框架,用于自动和弹性的多机器人编队导航。EFLUX提取结构化场景表示,并使用LLM共同推理变形动作(如缩放和剪切)和重构动作(如分裂和合并)。这些策略随后通过闭环生成、验证和纠正管道转化为可执行的每个机器人的航点。模拟和硬件实验表明,EFLUX在受限环境中实现了安全、连续和弹性的编队导航,与基线相比减少了死锁和导航失败,同时保持了多机器人的协调一致。

Enabling 24-hour Agricultural Robotics: Unsupervised Day-to-Night Cross-Modal Image Translation for Nighttime Visual Navigation
实现24小时农业机器人:无监督昼夜跨模态图像翻译用于夜间视觉导航
Abstract
While visual navigation has been extensively studied in agricultural robotics, most existing systems assume daytime conditions. In fact, deploying autonomous robots at night offers significant advantages, including 24-hour crop and soil monitoring, fruit harvesting, and nocturnal pest detection. Modern vision-based systems, however, rely heavily on large-scale well-annotated image datasets, which remains challenging to obtain for nighttime operation scenarios. To address this, we propose an unsupervised image translation framework that converts daytime plant-row RGB images into near-infrared (NIR) nighttime counterparts without requiring pixel-to-pixel supervision. This enables the direct reuse of daytime semantic labels for training nighttime perception models. In particular, by incorporating a pre-trained Contrastive Language-Image Pre-training (CLIP) model, the proposed framework is designed to preserve semantic consistency during day-to-night translation. Additionally, a visibility mask is introduced to account for the limited effective range of NIR illumination in nighttime scenes. We conduct comparative evaluations with state-of-the-art image translation baselines and demonstrate higher image qualities, as supported by improved performance in downstream semantic segmentation for nighttime visual navigation. For evaluation, we utilize AgriNight--a novel dataset comprising 428 daytime and 549 nighttime images collected using night-vision-equipped mobile robots in agricultural fields and manually annotated with pixel-wise semantic labels--and introduce it as the first benchmark for nighttime agricultural visual navigation. We also perform real-time autonomous navigation experiments with a physical robot operating at night. The data and code are available at: https://github.com/mamorobel/AgriNight.

尽管视觉导航在农业机器人领域得到了广泛研究,但大多数现有系统假设是在白天条件下运行。实际上,在夜间部署自主机器人具有显著优势,包括24小时作物和土壤监测、果实采摘以及夜间害虫检测。然而,现代基于视觉的系统在很大程度上依赖于大规模的高质量标注图像数据集,而在夜间操作场景中获取这样的数据集仍然具有挑战性。为了解决这个问题,我们提出了一种无监督图像翻译框架,该框架能够将白天植物行的RGB图像转换为近红外(NIR)夜间图像,而无需逐像素的监督。这使得可以直接重用白天的语义标签来训练夜间感知模型。特别地,通过引入预训练的对比语言-图像预训练(CLIP)模型,所提框架旨在保持昼夜翻译过程中的语义一致性。此外,引入了可见性掩码,以考虑夜间场景中NIR照明的有效范围有限。我们与最先进的图像翻译基线进行了比较评估,结果显示图像质量更高,并且在夜间视觉导航的下游语义分割任务中表现得到了改善。为了评估,我们利用AgriNight——一个新颖的数据集,包含428张白天图像和549张夜间图像,这些图像是通过配备夜视设备的移动机器人在农业领域收集的,并手动标注了逐像素的语义标签——并将其作为夜间农业视觉导航的第一个基准。此外,我们还进行了夜间物理机器人实时自主导航实验。数据和代码可在以下网址获取:https://github.com/mamorobel/AgriNight。

Robust In-Hand Manipulation via Priors in Reinforcement Learning and Mechanical Design
通过强化学习和机械设计中的先验实现稳健的手内操作
Abstract
In-hand manipulation without external sensing is challenging due to uncertainties from finger-object contacts and disturbances by gravity. While reinforcement learning has shown promise in learning complex finger gaiting, existing approaches do not prioritize maintaining well-conditioned grasps for sustained manipulation. We introduce two complementary physics priors for robust in-hand rolling: a global grasp-quality prior derived from classical grasp analysis and a local contact-geometry prior based on fingertip curvature. The grasp-quality prior is used as a dense reward-shaping term that encourages well-distributed contacts with improved worst-case wrench resistance. The contact-geometry prior is expressed in the fingertip geometry that mechanically shapes the contact interface toward task-aligned rolling while reducing off-axis drift. We evaluate the effect of these priors on learning in-hand rolling manipulation for a multifingered robotic hand manipulating three different objects at four palm orientations. Results show significant improvement in rotation efficiency, grasp stability, and disturbance rejection, suggesting that physics priors embedded in both learning and fingertip morphology improve task robustness and sim-to-real transfer.

GaitSpan: Growing Humanoid Locomotion from Walking to Running
GaitSpan:从行走到奔跑的类人运动发展
Abstract
A humanoid that can walk should not relearn locomotion from scratch to jog or run. Yet current approaches often obtain gait diversity by prescribing gait schedules, imitating motion clips, training experts to switch between or distilling skills into one policy. These strategies can produce impressive behaviors, but offer limited flexibility across continuous speed commands, terrains, and morphologies. We study skill growth with GaitSpan, a framework that expands a pretrained, basic walking policy into faster locomotion. It treats walking as a seed skill: reusable motor structure for balance, support, body coordination, and contact transition that can be regenerated at new rhythms, extended into longer/higher strides, and corrected by residual adaptation. This expansion has three aspects: 1) rhythm generation, which modulates the frozen walking policy with multiple internal clocks and learns command-conditioned combinations of the resulting canonical actions; 2) stride shaping, which rewards dynamic locomotion patterns appropriate for higher commanded speeds using a physically grounded objective inspired by spring-loaded inverted pendulum dynamics; and 3) residual adaptation, which captures motion details not accounted for by rhythm generation or stride shaping. GaitSpan is the first to deliver a single command-conditioned humanoid policy that spans walking, jogging, and running-like regimes covering a continuous speed range, transfers across morphologies, and deploys zero-shot on unseen sim-to-sim, and real-world terrains. Compared with baselines either trained with multi-experts or imitation from humans, it learns faster and achieves stronger gait performance.

一个能够行走的类人机器人不应该从头开始重新学习运动以进行慢跑或奔跑。然而,目前的方法通常通过规定步态时间表、模仿运动片段、训练专家在不同步态之间切换或将技能提炼为一个策略来获得步态多样性。这些策略可以产生令人印象深刻的行为,但在连续速度指令、地形和形态方面提供的灵活性有限。我们研究了技能增长,提出了GaitSpan,一个将预训练的基本行走策略扩展到更快运动的框架。它将行走视为一种种子技能:可重用的运动结构,用于平衡、支撑、身体协调和接触过渡,可以在新的节奏下重新生成,扩展为更长/更高的步幅,并通过残余适应进行修正。这种扩展有三个方面:1)节奏生成,通过多个内部时钟调节冻结的行走策略,并学习命令条件下的结果典范动作的组合;2)步幅塑造,使用受弹簧加载倒摆动力学启发的物理基础目标,奖励适合于更高命令速度的动态运动模式;3)残余适应,捕捉节奏生成或步幅塑造未考虑的运动细节。GaitSpan首次提供一个单一的命令条件类人政策,涵盖行走、慢跑和奔跑类的运动状态,覆盖连续速度范围,能够跨形态转移,并在未见的模拟到模拟和现实世界地形上进行零样本部署。与经过多专家训练或模仿人类的基线相比,它学习更快,并实现更强的步态表现。

A Behavioral State Vocabulary in Sony ERS-111 R-CODE
索尼 ERS-111 R-CODE 中的行为状态词汇
Abstract
This paper presents a corpus-level analysis of generated behavior diagrams derived from Sony's R-CODE sample distribution for the ERS-111 AIBO. Rather than reading each script in isolation, the study compares named states across the corpus to identify the recurring control vocabulary that structures the sample set. The resulting aggregate shows that many superficially different routines are built from a compact embodied grammar centered on initialization, sensing, iterative action, synchronization, and recovery. In addition to historical analysis, the paper argues that this form of state-based abstraction is useful as an intermediate representation for constructing new encapsulated behavior routines, especially on constrained native robotic systems where deterministic control, direct hardware access, and modular behavioral composition remain important.

More than a Manipulator: Planning Propellant-Free Attitude Maneuvers for Free-Floating Spacecraft
不仅仅是一个操纵器:为自由漂浮航天器规划无推进剂姿态机动
Abstract
Spacecraft attitude control is traditionally achieved using momentum exchange devices or propellant-consuming thrusters. Meanwhile, a growing number of missions require robotic manipulators, which are typically treated as disturbance sources to be rejected rather than as actuators for spacecraft reorientation. This work investigates the use of manipulator motions for propellant-free attitude control by formulating a trajectory optimization problem with critical joint and collision avoidance constraints. Using an interior point solver for the resulting nonlinear program, complex slew and detumble trajectories are demonstrated for a range of spacecraft-manipulator systems with varying kinematic complexity and mass properties. The achievable control authority is compared directly with that of reaction wheel arrays via momentum and torque envelopes, demonstrating the potential for manipulators to serve as redundant or even primary attitude control systems. This work provides a framework for using manipulators as multipurpose attitude control actuators, with particularly promising applications in in-space assembly and manufacturing when grasping payloads with high relative mass fractions.

Analysis of Mutual and Referential Human and Robot Gazes in a Collaborative Word Association Game
人类与机器人在协作词汇联想游戏中的相互与指向性注视分析
Abstract
Robot gaze is a major component of human-robot dialogue coordination. Most studies of gaze in human-robot dialogue focus on face-to-face social conversations, but little is known about gaze in demanding task-focused interactions. In this paper, we investigate how the gaze of a robot game partner affects human visual attention and if humans tend to direct confirmation-seeking gazes towards the robot. In our study, we let participants play a collaborative word association game with a NAO robot acting as an embodied, LLM-driven conversational partner. Our experiments are conducted under two conditions, which implement mutual and referential gazes of the robot respectively. We record participants' gaze using eye tracking glasses and analyze the interactions using gaze coordinates, speech segments, key events and areas of interests. We find that robot gaze orientation does not affect the time to first fixation on words the robot proposed. We also find that participants gaze more often at the robot when their dialogue line contains confirmation requests, compared to when it does not. Our results indicate (likely also due to the cognitively demanding nature of the game) that the verbal aspect of this task overshadows the effects of referential robot gaze. These findings offer valuable insights for designing and validating robot gaze and turn-taking behavior in collaborative tasks which require coordination and efficient communication.

Contract-Grounded Behavior Tree Synthesis via Coding Agents
基于合同的行为树合成通过编码代理
Abstract
Synthesizing deployable robot behavior trees (BTs) from natural language (NL) requires grounding to ensure every generated BT references only skills a robot can actually execute. Existing LLM-based BT synthesis approaches often place this grounding responsibility on the prompt author. This makes deployment brittle when the author does not know which skills the robot can execute, how those skills are parameterized, or how the robot runtime software constrains valid BT structure. This paper proposes a contract-grounded BT synthesis architecture in which a coding agent queries a robot-side Model Context Protocol (MCP) server to retrieve an explicit contract consisting of a skill library, permitted BT operators, and optional BT composition templates, before synthesizing a BT for validation and execution. In our framework, non-expert operators issue NL commands without knowledge of robot implementation details, while a robot runtime validation gate enforces correctness before execution. We evaluate two LLMs, a closed model (Sonnet 4.6) and a smaller open-source model (Gemma4:31b), across 110 simulated tasks in PyRoboSim and 14 tasks on a physical Husarion Panther robot. Results show that contract grounding enables near-perfect BT validation and high task success, that BT composition templates substantially recover success on reactive control-flow tasks for the smaller model, and that the architecture transfers to physical hardware running a Nav2 stack opaque to both operator and agent.

DiffRadar: Differentiable Physics-Aware Radar SLAM with Gaussian Fields
DiffRadar:具有高斯场的可微物理感知雷达SLAM
Abstract
Radar sensing is increasingly used in mobile systems because it operates reliably under poor lighting, adverse weather, and privacy-sensitive settings where cameras and LiDAR often fail. However, most existing radar SLAM systems estimate motion through scan matching on discretized radar heatmaps, which breaks geometric continuity and fails to capture key radar sensing properties, often leading to unstable pose estimation and degraded mapping in regenerate or dynamically changing environments. We present DiffRadar, a real-time radar SLAM system that models radar observations as a differentiable, physics-aware Gaussian field rather than discrete scans. DiffRadar represents the scene as anisotropic Gaussian primitives and renders radar measurements in range-azimuth and Doppler-azimuth spaces through a differentiable radar forward model, enabling joint optimization of robot pose and scene structure directly from radar measurements. We implement DiffRadar on commodity FMCW radar hardware and evaluate it on both the public Radarize benchmark and a controlled stress-test suite that targets common radar SLAM failure modes, including corridor degeneracy, motion regime transitions, dynamic clutter, and long-horizon loop closures. DiffRadar achieves substantial reductions in trajectory error on the benchmark, with especially large gains under feature-poor corridor motion, while more than doubling map consistency and maintaining real-time performance at 70 FPS. These results show that modeling radar observations directly in the signal domain enables substantially more robust and consistent radar-only SLAM for mobile platforms.

Flatness-Preserving Residual Learning for Real-Time Tight Quadrotor Formation Flight
保持平坦性的残差学习用于实时紧凑四旋翼编队飞行
Abstract
Quadrotors flying in tight formations are severely affected by turbulent aerodynamic interactions, such as downwash, that can cause catastrophic collisions if left unmodeled. To compensate for these effects, we propose a physics-informed residual dynamics learning framework that captures complex aerodynamic interactions while ensuring the joint multi-quadrotor system remains differentially flat. We leverage this preserved flatness to design a computationally efficient feedback linearization controller that is easily tunable with linear control techniques and cancels aerodynamic disturbances via feedforward compensation. Hardware experiments demonstrate our framework reduces average tracking errors by 31% compared to nominal baselines. Crucially, our lightweight approach matches the tracking performance of state-of-the-art nonlinear model predictive control (NMPC) while requiring an order of magnitude less computation. We are the first to show that stable, tight formation flight can be achieved with under 30 seconds of training data and a 5ms loop rate, unlocking high-fidelity aerodynamic compensation for compute-constrained flight stacks.

Reducing Temporal Redundancy for Efficient Vision-Language-Action Inference
减少时间冗余以实现高效的视觉-语言-动作推理
Abstract
Vision-Language-Action (VLA) models exhibit strong generalization for robotic manipulation, yet their high inference latency limits real time deployment. We identify two primary sources of temporal redundancy in existing VLA pipelines: repeated visual encoding of highly similar consecutive frames and multi step iterative sampling in diffusion based policies. To address this, we propose a system level acceleration strategy that reduces computation in both perception and action generation. On the perception side, we incrementally update only tokens corresponding to dynamic scene regions instead of re-encoding entire frames. On the policy side, we compress diffusion sampling into a compact 2-step schedule through efficiency oriented training while preserving action precision. Experiments on Libero, RobotWin, and Real Robot Platforms demonstrate over 2 times speedup while maintaining high performance, achieving up to 98% success rate on general manipulation benchmarks. Our codes will be released on Github.

VistaVLA: Geometry- and Semantic-Aware 3D Gaussian-Grounded VLA for Robotic Manipulation
VistaVLA:几何和语义感知的基于3D高斯的视觉-语言-动作模型用于机器人操作
Abstract
Vision-Language-Action (VLA) models have emerged as a powerful end-to-end paradigm for robotic manipulation by mapping language instructions and 2D visual inputs directly to actions. However, these models lack an explicit, scene-level 3D representation, limiting their ability to reason over spatial layouts and geometric constraints. While recent efforts incorporate explicit 3D cues, such as depth maps or point clouds, to improve geometric awareness, they primarily capture low-level structures and lack high-level semantic grounding in 3D space. In human cognition, interaction with the physical world relies on a 3D semantic cognitive map - an internal mental model that integrates spatial layouts with semantic context to enable persistent, viewpoint-invariant reasoning. In light of this, we present VistaVLA, a novel two-stage framework that constructs a geometry- and semantics-aware 3D cognitive representation from 3D Gaussian primitives and grounds it as compact context tokens for VLA policy learning. Specifically, VistaVLA lifts multi-view vision-language features into 3D Gaussian primitives, forming geometry-anchored semantic tokens that align view-consistent spatial grounding with 2D visual feature spaces. To make this 3D representation computationally tractable for effective VLA control, we introduce Merge-then-Query (MtQ), a token summarization mechanism. MtQ compresses dense Gaussian primitives into a highly compact set of spatially informative tokens, achieving a 99% token reduction while preserving action-relevant 3D layouts and semantic context. Extensive evaluations in both simulated and real-world environments demonstrate the effectiveness of VistaVLA. Notably, in real-world scenarios, VistaVLA improves success rates by 22.8% across seven real-world tasks and by 30.0% over the VLA-Adapter baseline on challenging out-of-distribution tasks.

StratMamba: Strategic and Reactive Stream Partitioning for Path-Efficient LiDAR-Based Obstacle Avoidance
StratMamba:用于路径高效的基于LiDAR的障碍物规避的战略性和反应性流分区
Abstract
This paper proposes StratMamba, a dual-stream Mamba-based temporal modeling architecture, to more efficiently capture long-horizon temporal dependencies required for robot navigation in complex and obstacle-rich environments. StratMamba leverages a combination of fast-decay and slow-decay memory architectures, where the fast-decay component processes high-frequency LiDAR data for reactive obstacle avoidance, while the slow-decay component maintains longer-horizon goal information for strategic planning. We perform extensive evaluations of different obstacle avoidance scenarios in IsaacLab and Gazebo, while also validating successful sim-to-real deployment on a Unitree GO1 quadruped robot navigating in the presence of static/dynamic obstacles. Comparisons with other temporal RL baselines, such as LSTM, Transformer, and Vanilla-Mamba, show that our StratMamba achieves exceptional temporal reasoning efficiency with a lower timeout rate, while maintaining the fastest navigation speed (576 median steps, 5.0% better than Vanilla-Mamba). It also achieves the highest path optimality (0.915 path efficiency) across all baselines. Real-world evaluation reveals that StratMamba maintains more robust performance across extended LiDAR ranges compared to vanilla Mamba and the Transformer, demonstrating that dual-stream partitioning effectively balances reactive safety with strategic navigation under challenging sensing conditions.

Model-Based Diffusion Optimal Control for Multi-Robot Motion Planning
基于模型的扩散最优控制用于多机器人运动规划
Abstract
Multi-Robot Motion Planning in continuous environments, where robots must generate dynamically feasible, collision-free trajectories, is challenging due to the combinatorial growth of the joint trajectory space and the difficulty of enforcing dynamic feasibility and hard safety constraints. Recent approaches recast trajectory planning as probabilistic inference, sampling from a posterior over trajectories using diffusion models whose score functions are learned from demonstration data. While showing promising performance, these approaches are limited: they often rely on sizable demonstration datasets and struggle to rigorously enforce dynamics and hard safety constraints during sampling. To this end, we introduce Model-Based Diffusion Optimal Control (MDOC), a model-based diffusion planner that efficiently produces dynamically feasible trajectories without relying on data. Crucially, we show that MDOC's safety mechanism -- combining known dynamics models with Control Barrier Function-constrained projections -- naturally scales to multi-robot planning settings through Conflict-Based Search. Across simulation experiments, this integrated method consistently outperforms representative baseline planners in sample efficiency, geometric smoothness, and success rate, while reducing computation time and producing collision-free trajectories.

在连续环境中进行多机器人运动规划是一项具有挑战性的任务,因为机器人必须生成动态可行且无碰撞的轨迹,这受到联合轨迹空间的组合增长和强制执行动态可行性及硬安全约束的困难所影响。近期的方法将轨迹规划重新表述为概率推断,通过扩散模型从轨迹的后验分布中采样,这些模型的评分函数是从示范数据中学习得来的。尽管表现出良好的性能,这些方法仍然存在局限性:它们通常依赖于大量的示范数据集,并且在采样过程中难以严格执行动态和硬安全约束。为此,我们提出了基于模型的扩散最优控制(Model-Based Diffusion Optimal Control, MDOC),这是一种基于模型的扩散规划器,能够高效地产生动态可行的轨迹,而无需依赖数据。关键在于,我们展示了MDOC的安全机制——将已知的动态模型与控制障碍函数约束的投影相结合——通过基于冲突的搜索自然地扩展到多机器人规划设置。在模拟实验中,这种集成方法在样本效率、几何平滑性和成功率方面始终优于代表性的基线规划器,同时减少了计算时间并生成了无碰撞的轨迹。

Deployable Human Preference Alignment in Robotics: Learning Representative Rewards from Diverse Human Preferences
可部署的人类偏好对齐在机器人技术中的应用:从多样化人类偏好中学习代表性奖励
Abstract
Aligning robot policies with human preferences is essential for deployment to diverse end users. In per-user alignment approach, preference feedback is often sparse, so learning becomes unstable and vulnerable to human preference noise, and a growing number of individualized policies makes validation difficult before deployment. A single shared policy approach to user alignment avoids this cost but fails to capture heterogeneous preferences and often neglects minority preferences. To address these challenges, we introduce Preference-based REward Clustering (PREC), a novel framework that learns a compact set of policies from binary preference labels provided by diverse users. From a dataset of user trajectories and their preference labels, PREC first sets the labels aside and aggregates trajectories across users to learn a population-level shared trajectory encoder, alleviating limited per-user coverage and avoiding label noise during representation learning. Using this representation, PREC jointly assigns users to preference-coherent clusters and learns a representative reward model per cluster using preference labels, from which a policy is optimized for each cluster. Clustering similar users compensates for the limited number of labels available from each user and mitigates the effect of label noise. At the same time, maintaining a manageable number of reward models reduces the validation burden at deployment. Experiments across diverse simulated locomotion environments show that PREC groups users who label different trajectory subsets into preference-coherent clusters more accurately than baseline methods. Under sparse and noisy feedback, policies trained with PREC improve all three social welfare metrics over an existing single shared-policy user-alignment approach and even outperform per-user alignment approaches.

将机器人策略与人类偏好对齐对于向多样化最终用户的部署至关重要。在每用户对齐的方法中,偏好反馈通常是稀疏的,因此学习变得不稳定且容易受到人类偏好噪声的影响,个性化策略的数量不断增加使得在部署前的验证变得困难。共享单一策略的方法避免了这一成本,但未能捕捉异质偏好,且往往忽视少数群体的偏好。为了解决这些挑战,我们引入了基于偏好的奖励聚类(Preference-based REward Clustering, PREC),这是一个新颖的框架,能够从多样化用户提供的二元偏好标签中学习一组紧凑的策略。通过用户轨迹及其偏好标签的数据集,PREC首先将标签搁置,并在用户之间聚合轨迹,以学习一个人口级别的共享轨迹编码器,从而缓解每用户覆盖有限的问题,并在表示学习过程中避免标签噪声。利用这一表示,PREC共同将用户分配到偏好一致的聚类中,并使用偏好标签为每个聚类学习一个代表性的奖励模型,从中优化每个聚类的策略。聚类相似用户弥补了每个用户可用标签数量有限的问题,并减轻了标签噪声的影响。同时,保持可管理数量的奖励模型减少了部署时的验证负担。在多样化的模拟运动环境中的实验表明,PREC比基线方法更准确地将标记不同轨迹子集的用户分组到偏好一致的聚类中。在稀疏和噪声反馈下,使用PREC训练的策略在所有三个社会福利指标上优于现有的单一共享策略用户对齐方法,甚至超越了每用户对齐的方法。

Infra-Swarm: Robust Vision-Based Multi-Robot Swarming via Near-Infrared Spectral Vision
红外群体:基于近红外光谱视觉的鲁棒多机器人群体
Abstract
Distributed swarms typically rely on either active wireless communication or passive vision, and they are frequently hindered by bandwidth constraints or environmental sensitivity. This paper proposes Infra-Swarm, a robust vision-based swarm. Each robot is equipped with a near-infrared light source and four ordinary gray-scale cameras. The Infra-Swarm system directly measures the centimeter-level 3D position of neighbors based on the position (bearing) and intensity (strength) of optical flares in the captured images. By utilizing 940 nm narrow-band filters to physically reject 99.2% of ambient light interference, the perception front-end achieves hardware-level robustness against illumination variations. Furthermore, its minimal computational overhead provides a resilient foundation for the massive scalability of robotic collectives on resource-constrained hardware.

A Bearing-Strength Method for Motion Estimation of Unknown Energy Emitters
一种用于未知能量发射器运动估计的方位强度方法
Abstract
This paper studies motion estimation of moving energy emitters using passive sensors. The emitters may be light, acoustic, or radio sources. While the bearing vector pointing from the sensor to the emitter can be easily obtained, existing approaches mainly rely on the bearing-only motion estimation method. However, this method suffers from a fundamental limitation that the sensor must have lateral motion to ensure observability. Unfortunately, this lateral motion requirement often conflicts with the sensor's desired motion in many tasks. In this paper, we point out that the received signal strength, which can also be obtained easily in many ways, can greatly enhance motion estimation. Surprisingly, this strength information has not been well explored so far. Here, we propose a new bearing-strength method to fully exploit both the bearing and strength measurements. Our theoretical analysis shows that the system observability is significantly enhanced in the sense that the lateral motion condition is not required anymore. Real-world experimental results verify the proposed method and the theoretical analysis. It is notable that the benefit of the proposed method comes with no additional cost since it simply utilizes the received strength information that has not been fully exploited in the past.

Mind the Gap: Promises and Pitfalls of Hierarchical Planning in LeWorldModel
关注差距:LeWorldModel中层次规划的承诺与陷阱
Abstract
We investigate whether temporal hierarchy can improve LeWorldModel on long-horizon goal-conditioned control. We introduce Hi-LeWM, an extension that freezes the pretrained low-level LeWM and adds high-level planning over latent subgoals. We evaluate Hi-LeWM on PushT and Cube across increasing goal offsets. Hierarchy does not automatically improve performance: at short horizons, the best configuration uses a one-step high-level horizon, while longer horizons reveal a mismatch between the learned high-level action space and the inference-time search distribution. Experiments with true future latent subgoals show that the frozen low-level controller can execute well-aligned intermediate targets, indicating that high-level subgoal generation is the main bottleneck. Unconstrained search can select latent macro-actions that appear favorable under the learned model but produce poor control targets. Constraining search around macro-actions encoded from training trajectories, with appropriate subgoal execution timing, recovers useful hierarchical regimes, improving over flat LeWM by +11.3 percentage points at medium-range horizons and +14.7 percentage points at the longest PushT horizon. Overall, temporal abstraction can benefit compact frozen LeWM, but only when high-level search remains compatible with the low-level controller

TrustVLA: Mechanism-Guided Inference-Time Defense Against Vision-Language-Action Backdoors
TrustVLA:机制引导的推理时防御视觉-语言-动作后门
Abstract
Vision-Language-Action (VLA) models are deployed through pipelines that end users cannot audit, and a poisoned VLA can behave normally on clean observations while a small visual trigger redirects a long-horizon robot policy before any failure becomes observable. Existing vision or language defenses rarely explain what a triggered VLA representation looks like or how to recover behavior without retraining. We study this gap through two independently proposed VLA attacks from groups with distinct injection strategies, BadVLA and INFUSE; the latter persists after downstream clean adaptation. Across the evaluated poisoned models, we identify a recurring internal mechanism: a \emph{compact causal footprint}, namely a small visual support that is attention-seeded, spatially compact, and \emph{causal} in a precise sense -- masking it returns a clean-calibrated evidence-evolution score to the normal operating region. This footprint motivates TrustVLA, a mechanism-guided inference-time defense that adapts the Dirichlet evidence framework from trusted classification to monitor per-token, per-layer epistemic uncertainty in VLA policies. With only a small clean calibration set, TrustVLA (i)~detects abnormal evidence evolution, (ii)~localizes the compact support by counterfactual mechanism-score drop, and (iii)~recovers the observation by localized inpainting. Across OpenVLA/LIBERO and $\pi_{0.5}$ transfer evaluations, TrustVLA reduces attack success while preserving clean-task performance, providing a retraining-free, mechanism-guided defense for visual-triggered VLA backdoors.

Streamlining stereo differentiable rendering for marker-free real-time tracking of surgical robots
简化立体可微渲染以实现无标记手术机器人实时跟踪
Abstract
Purpose: Marker-based tracking of surgical robots is occlusion-prone in cluttered operating rooms. We evaluate stereo differentiable rendering for marker-free, real-time robot pose tracking, potentially improving safety, reducing setup time, and enabling multi-robot interaction. Methods: We extend the markerless pose estimation framework roboreg to online dynamic tracking via (i) sequential optimisation that propagates pose estimates across frames with motion-adaptive hyperparameter tuning, and (ii) CUDA stream parallelisation of segmentation and optimisation, combined with CUDA-graph accelerated segmentation. We evaluate on 38 unobstructed and 5 occluded displacement sequences with static start/end ground-truth calibrations and dynamic marker-based reference tracking. Results: We achieve real-time 1080p tracking at 30 fps (up from 14 fps for vanilla roboreg), matching the camera frame rate. Accuracy reaches 1.7 cm / 0.6 deg against static ground truth and 1.2 cm mean 3D error over 27,460 frames against the marker-based reference (1.53 cm over 1,242 occluded frames). Our method outperforms FoundationPose by 11% in dynamic estimation (63% under occlusion) and 250% in static estimation, with 6x faster inference. Conclusions: Stereo differentiable rendering enables real-time, high-resolution marker-free surgical robot tracking, on par with marker-based approaches and surpassing foundation-model baselines.

Instance-Enriched Semantic Maps for Visual Language Navigation
实例丰富的语义地图用于视觉语言导航
Abstract
Visual Language Navigation (VLN) aims to enable an embodied agent to navigate complex environments by following natural language instructions. Recent approaches build semantic spatial maps and leverage Large Language Models (LLMs) for reasoning and decision making. Despite these advances, existing systems lack instance-level object detail and robustness to diverse user queries, limiting reliable navigation in complex indoor environments. To address these limitations, we propose Instance-Enriched Semantic Maps, a unified framework with three key contributions: (1) Instance-level two-and-a-half-dimensional (2.5D) rich information mapping that constructs maps from color and depth observations via open-vocabulary panoptic segmentation, preserving vertical distinctions and capturing small objects, while storing diverse semantic attributes and natural language captions enriched with room-level context. (2) Robust query processing via LLM-based target selection, which dynamically routes queries across type-specialized experts and integrates their outputs through score-level fusion, enabling consistent goal selection across diverse query formulations. (3) Storage-efficient semantic representation that achieves approximately 96% reduction compared to three-dimensional (3D) scene-graph approaches while preserving sufficient spatial information for navigation. The proposed 2.5D representation outperforms the 3D baseline by over 27% in prediction-normalized Area Under the Curve (AUC). In navigation experiments, our method achieves over 17% improvement in object retrieval and over 23% in navigation success compared to the baseline across diverse query types.

Jetson-PI: Towards Onboard Real-Time Robot Control via Foresight-Aligned Asynchronous Inference
Jetson-PI:通过前瞻性对齐异步推理实现机载实时机器人控制
Abstract
Vision-Language-Action (VLA) models have achieved impressive performance on diverse embodied tasks. However, deploying VLA models on low-power onboard devices, such as the Jetson Orin, remains challenging due to their high computational complexity, which leads to substantial inference latency and low control frequency. Asynchronous inference can partially mask this latency by parallelizing action execution and subsequent inference, but it introduces two critical issues: perception-execution misalignment and long reaction time. In this paper, we propose Jetson-PI, a method for efficient VLA deployment on onboard devices via Foresight-Aligned Asynchronous Correction. To address misalignment, we train a lightweight future correction module that predicts future environment representation conditioned on committed actions, enabling the action expert to directly predict actions from the future time step. To reduce reaction time, we introduce confidence-based scheduling optimization that adaptively balances VLM and action expert invocations, complemented by system-level accelerations including CUDA graph reuse, GPU-resident intermediate buffering, and flow unrolling. Extensive experiments demonstrate that Jetson-PI achieves 8.66x and 5.41x improvements in control frequency compared with naive PyTorch and vla.cpp on NVIDIA Jetson Orin, while outperforming VLASH by 14.8\% in average success rate on the LIBERO benchmark. The code of our asynchronous algorithm is available on https://github.com/PKU-SEC-Lab/Jetson-PI, and our efficient llama.cpp-based inference engine is available on https://github.com/PKU-SEC-Lab/Jetson-PI-Edge.

Vision-Based Dribbling for Humanoid Soccer via Privileged Representation Learning
基于视觉的人形足球运球通过特权表示学习
Abstract
Recent advances in humanoid robotics have highlighted the importance of deployable loco-manipulation skills. Dribbling a soccer ball while evading active opponents requires simultaneous balance, precise ball control, and awareness of a dynamic adversary under onboard sensing and real-time constraints. Existing approaches typically separate perception and motion, which can be effective in controlled settings but may fail under occlusions, fast ball movements, and complex opponent interactions, since perception is not directly optimized for control. We propose an integrated approach in which a temporal depth encoder is embedded into a reinforcement learning policy through a task-specific projection layer. We apply this framework to a simulated Booster T1 humanoid robot and show that it is possible to learn vision-based, opponent-aware dribbling directly from depth observations, without explicit state estimation or privileged scene information. The learned policy achieves 100% success in nominal target-driven dribbling and 96% success with a single static obstacle, while reaching 46% success against an actively moving ball-attacker opponent. These results demonstrate that the proposed framework supports robust vision-based dribbling in nominal and moderately dynamic settings, and provides a strong foundation for handling more challenging moving-adversary scenarios.

Globalized Constrained Stein Variational Inference for Diverse Feasible Robot Motion Planning
全球化约束斯坦变分推断用于多样化可行的机器人运动规划
Abstract
Robot motion planning is inherently multimodal, yet classical planners typically return only a single solution. Probabilistic formulations address this limitation by maintaining a distribution over motions, allowing the planner to reason over multiple low-cost alternatives. In robotics, however, motion samples must also satisfy strict constraints, including collision avoidance, joint limits, contact conditions, and dynamics consistency. These hard requirements make motion sampling substantially more challenging: within a limited planning budget, the ensemble must cover diverse low-cost motions while ensuring that every sample remains feasible under the relevant constraints. We propose SteinSQP (Stein Variational Sequential Quadratic Programming), a constrained Stein variational inference method for diverse feasible robot motion sampling. SteinSQP evolves an interacting particle ensemble, as in Stein variational methods, while embedding constraints directly into a kernel-space SQP subproblem. We solve the resulting constrained Stein-Newton subproblem with a GPU-friendly matrix-free primal-dual algorithm, enabling efficient batched ensemble updates. To globalize the method, we introduce an ensemble-level merit function that jointly balances objective value, constraint violation, and particle diversity. Across five constrained motion-planning tasks, SteinSQP returns fully feasible ensembles while preserving diverse motion alternatives. Compared with first-order constrained Stein baselines and serial multistart nonlinear programming, SteinSQP shows faster and more robust ensemble convergence in terms of iterations, improves particle-wise feasibility, and achieves faster batched time-to-solution on challenging robot-scale tasks.

机器人运动规划本质上是多模态的,但传统规划器通常只返回单一解。概率性形式化方法通过保持运动的分布来解决这一限制,使规划器能够在多个低成本替代方案中进行推理。然而,在机器人领域,运动样本还必须满足严格的约束条件,包括避免碰撞、关节限制、接触条件和动力学一致性。这些硬性要求使得运动采样变得更加具有挑战性:在有限的规划预算内,集群必须覆盖多样化的低成本运动,同时确保每个样本在相关约束下保持可行。我们提出了SteinSQP(斯坦变分序列二次规划),这是一种用于多样化可行机器人运动采样的约束斯坦变分推断方法。SteinSQP演化了一个相互作用的粒子集群,类似于斯坦变分方法,同时将约束直接嵌入到核空间的SQP子问题中。我们使用一种适合GPU的无矩阵原始-对偶算法来解决得到的约束斯坦-牛顿子问题,从而实现高效的批量集群更新。为了全球化该方法,我们引入了一种集群级的优值函数,联合平衡目标值、约束违反和粒子多样性。在五个约束运动规划任务中,SteinSQP返回完全可行的集群,同时保留多样化的运动替代方案。与一阶约束斯坦基线和串行多起始非线性规划相比,SteinSQP在迭代次数上表现出更快和更稳健的集群收敛,改善了粒子级的可行性,并在具有挑战性的机器人规模任务上实现了更快的批量求解时间。

Directional Constraints for Efficient Exploration in Safe Reinforcement Learning
安全强化学习中的高效探索方向约束
Abstract
Reinforcement Learning has revolutionized the landscape of robotic research, allowing robust learning of complex robotic skills in simulation. However, real-world deployment in open-ended environments requires strong safety guarantees to prevent dangerous or harmful behaviors. Safe Reinforcement Learning methods address this requirement by enforcing safety constraints. Nevertheless, learning under constraints often reduces learning speed and could lead to suboptimal task performance, as the agent must solve a more complex constrained optimization problem compared to unconstrained settings. To tackle this issue, in this work, we propose an extension of the ATACOM framework, a state-of-the-art reliable safety layer that can be integrated with existing Reinforcement Learning algorithms to enforce constraints derived from prior knowledge of the system or learned directly from data. Our proposed method, named ATACOM Directional Constraints (ATACOM-DC), significantly improves the safety-performance trade-off by introducing directional constraints that distinguish between actions approaching and moving away from constraint boundaries, activating constraint enforcement only when necessary. We evaluate our method across a range of challenging robotic control tasks in simulation, analyzing both constraint-violation costs and achieved task performance.

Autonomous Tracking and Terminal Guidance of Moving Targets for Fixed-Wing UAVs
固定翼无人机的自主跟踪与末端引导移动目标
Abstract
This study introduces a unified control framework for fixed-wing unmanned aerial vehicles (UAVs) fitted with a pan-tilt (PT) camera, intended to perform an end-to-end mission spanning from initial target detection to accurate terminal engagement. The proposed system employs a three-phase strategy: a vision-based target acquisition phase, an NMPC-based tracking phase, and a terminal guidance phase. During tracking, the framework uses an Unscented Kalman Filter (UKF) to fuse YOLO-based visual detections with inertial measurements, enabling robust target state estimation under unknown dynamics. To ensure reliable visual contact, we introduce a constraint-aware Nonlinear Model Predictive Control (NMPC) strategy that incorporates Control Barrier Functions (CBFs) to explicitly prevent UAV self-occlusion -- a common limitation in fixed-wing tracking. Upon satisfying terminal engagement conditions, the system seamlessly transitions control to a quaternion-based Biased Proportional Navigation Guidance (BPNG) law, enforcing precise impact angle constraints. High-fidelity simulations demonstrate that the framework achieves stable, robust tracking and accurate terminal interception while strictly respecting the vehicle's dynamic limits and camera field-of-view constraints.

PixelLoop: Shortcut Topological Navigation with Pixel-Level Loops
PixelLoop:像素级循环的快捷拓扑导航
Abstract
Although topological mapping and navigation have been studied extensively, the specific role and downstream effect of loop closures in purely topological representations has received relatively little attention. Importantly, loop closure over topological maps is distinct from loop closure over globally referenced trajectories and metric maps. Building on recent denser topologies grounded in pixel-level, relative 3D geometry, we propose PixelLoop which introduces loop closures directly in pixel space. Unlike sparse image-level edges or pose-graph corrections in SLAM, our pixel-level closures act as dense topological shortcuts that alter planning connectivity and cost propagation rather than merely aligning coordinates. This dense connectivity enables stable any-point-to-any-point navigation and produces costmaps that align accurately with geometric shortest paths. In particular, we showcase the distinct advantage of applying loop closures to fine-grained pixel topologies rather than image-level topologies. Across extensive simulated experiments, PixelLoop achieves over 35% absolute improvement in both Success Rate and SPL compared to image-relative baselines, with the largest gains in scenarios requiring shortcut exploitation. Results are further validated through real-world mobile robot deployments, demonstrating that dense pixel-level loop closures provide a practical and robust foundation for topological visual navigation.

Unveiling Complex Collective Behaviors from Simple Rewards
从简单奖励揭示复杂集体行为
Abstract
Multi-agent Reinforcement Learning (MARL) holds great potential for robot swarms, but the black-box nature of neural policies complicates strategic analysis, limiting multi-robot applications. Furthermore, complex swarm behaviors can surprisingly emerge from simple rewards without explicit aggregation incentives. Unveiling the mechanisms behind this emergence is critical, but the disconnection between simple rewards and collective behaviors exacerbates interpretability challenges. This paper aims to reveal the hidden mechanisms in this process. We propose a two-stage EEC (\LinkIII) explanatory framework. This includes a novel analytical tool called the Agent Response Map (ARM), which reveals agents' decision-making patterns across space and identifies regions of aggregation and avoidance. ARM reveals that the robots implicitly learn the geometric fields of the environment and utilize these structures as desired targets for coordinated movement. We validate this finding across two distinct tasks: a cooperative multi-robot shape assembly and a competitive predator-prey pursuit-evasion. 1) In the cooperative task, ARM identifies the unoccupied target interior as the desired destination for robot navigation. As the center becomes occupied, this target region automatically shifts toward the boundary, demonstrating the robots' capacity to autonomously explore unoccupied areas. 2) In the competitive task, ARM surprisingly identifies the boundary of the predators' Voronoi diagram as the convergence destination for prey agents. Together, these two tasks demonstrate the capability of ARM to discover the hidden geometric structures underlying MARL policies in robot swarms.

UR-VC: Unsupervised Robotic Value Correction for Time-Derived Progress Proxies
UR-VC:用于时间衍生进度代理的无监督机器人价值修正
Abstract
Modern robot learning systems increasingly rely on dense progress or value signals to evaluate intermediate states, guide policy learning, and detect task completion, making the quality of these signals critical. Since such dense labels are rarely available at scale, normalized time within a demonstration is often used as a scalable substitute: later frames are treated as higher progress. However, this time-derived label is only a noisy proxy for physical task progress. In contact-rich manipulation, a robot may make progress and then lose it through slips, failed grasps, or partial undoing, while the time-derived label continues to increase monotonically. We introduce Unsupervised Robotic Value Correction (UR-VC), an offline, training-free method for correcting time-derived progress labels. UR-VC exploits a simple regularity in demonstration data: similar states often recur across different episodes, but at different timestamps. Instead of trusting the timestamp from a single trajectory, UR-VC retrieves similar states from other episodes and aggregates their time-derived labels to obtain a corrected progress estimate. UR-VC requires no manual progress labels, reward annotations, or additional value model. We evaluate UR-VC on real bimanual cloth flatten-and-fold data, a long-horizon deformable-object manipulation task with visible intermediate progress. The corrected labels capture local regressions and non-uniform progress that normalized time cannot represent, while preserving the overall task trend. We further use the corrected signal to construct advantage labels for VLA training, following recent advantage-conditioned policy learning. UR-VC shows a positive trend in real-robot task success under matched data, model, and training settings.

现代机器人学习系统越来越依赖于密集的进度或价值信号来评估中间状态、指导策略学习和检测任务完成,这使得这些信号的质量至关重要。由于此类密集标签在规模上很少可用,因此在演示中通常使用标准化时间作为可扩展的替代方案:后续帧被视为更高的进度。然而,这种时间衍生标签仅仅是物理任务进度的一个嘈杂代理。在接触丰富的操作中,机器人可能会取得进展,然后通过滑动、抓取失败或部分撤销而失去进展,而时间衍生标签则持续单调增加。我们提出了无监督机器人价值修正(UR-VC),这是一种离线、无训练的方法,用于修正时间衍生的进度标签。UR-VC利用演示数据中的一种简单规律:相似的状态通常在不同的剧集间重复出现,但时间戳不同。UR-VC不是依赖单一轨迹的时间戳,而是从其他剧集中检索相似状态,并聚合它们的时间衍生标签以获得修正的进度估计。UR-VC不需要手动进度标签、奖励注释或额外的价值模型。我们在真实的双手布料平整和折叠数据上评估UR-VC,这是一个具有可见中间进度的长时间跨度可变形物体操作任务。修正后的标签捕捉到局部回归和标准化时间无法表示的非均匀进度,同时保留整体任务趋势。我们进一步利用修正信号构建优势标签,以用于VLA训练,遵循最近的优势条件策略学习。在匹配的数据、模型和训练设置下,UR-VC在真实机器人任务成功率上显示出积极的趋势。

ExToken: Structured Exploration for Efficient Vision-Language-Action Reinforcement Fine-tuning
ExToken:高效视觉-语言-动作强化微调的结构化探索
Abstract
Reinforcement Learning (RL) has demonstrated significant potential for improving Vision-Language-Action (VLA) models on complex manipulation tasks. However, its practical scalability remains severely limited by the substantial cost of environmental interactions. In this work, we first investigate the exploration stagnation bottleneck in current VLA-RL frameworks and reveal that trajectory diversity is fundamentally more important to sample efficiency than the sheer quantity of collected rollouts. Motivated by these insights, we introduce RL Exploration Token (ExToken), a simple yet general framework that condition VLA policies on discrete behavioral priors derived from offline demonstrations for structured exploration. By conditioning the policy on different tokens during rollout collection, ExToken encourages the agent to explore diverse behavioral modes, substantially improving state-action coverage and exploration efficiency. To bridge exploration during training with deterministic inference at deployment, ExToken further incorporates a state-conditioned token selector that adaptively predicts effective behavioral modes for unseen scenarios. Extensive experiments across simulated and real-world robotic manipulation tasks demonstrate that ExToken consistently accelerates convergence, improves task performance, and exhibits strong robustness under highly constrained interaction budgets.

MAMMOTH: A Multi-Modal End-to-End Policy for Off-Road Mobility Robust to Missing Modality
MAMMOTH:一种对缺失模态具有鲁棒性的多模态端到端越野移动策略
Abstract
Reliable autonomous navigation in unstructured off-road environments remains a critical unsolved challenge due to extreme terrain diversity, drastic illumination variations and acute sensor degradation. Recent developments have approached the problem as a traversability costmap estimation or visual navigation task. However, many exhibit heavy reliance on RGB modality, leading to poor performance in varied illumination such as glares, shadows or low ambient light. Achieving robust generalization in such conditions requires integrating modalities that provide supplementary scene information. Such multi-modal methods suffer from a rigid dependency on the presence of near-perfect sensor inputs, leaving them unable to robustly handle sensor degradation or individual modality failure. To address these limitations, we introduce MAMMOTH (MAsking Multi-Modal inputs for Off-road Traversability Heuristic-informed navigation), a unified end-to-end navigation policy for robust off-road visual-goal-conditioned navigation and undirected exploration. Specifically, MAMMOTH efficiently fuses multi-modal observations (RGB, Thermal, 3D Pointcloud and Ego Velocity) and is trained with a modality dropout scheme, enabling it to generalize to missing modalities at inference time. Furthermore, we employ a diffusion policy to learn the joint conditional probability distribution of physically-grounded trajectories and a intrinsic traversability heuristic. MAMMOTH utilizes this heuristic to prefer safer, smoother trajectories. We validate MAMMOTH through extensive real-world robot experiments in distinct off-road environments, including night-time operation. Our results demonstrate superior performance, with significant improvements in collision avoidance, terrain-aware planning and generalization to missing modalities. The code and dataset used for this work will be made publicly available.

在非结构化的越野环境中实现可靠的自主导航仍然是一个关键的未解决挑战,原因在于极端的地形多样性、剧烈的光照变化和严重的传感器退化。近期的发展将这一问题视为可通行性成本图估计或视觉导航任务。然而,许多方法严重依赖于RGB模态,导致在眩光、阴影或低环境光等变化光照条件下表现不佳。在这种情况下实现鲁棒的泛化能力需要整合提供补充场景信息的模态。这类多模态方法受到对近乎完美传感器输入的严格依赖,无法有效处理传感器退化或单一模态故障。为了解决这些局限性,我们提出了MAMMOTH(MAsking Multi-Modal inputs for Off-road Traversability Heuristic-informed navigation),这是一种统一的端到端导航策略,旨在实现鲁棒的越野视觉目标条件导航和无向探索。具体而言,MAMMOTH高效地融合多模态观测(RGB、热成像、3D点云和自我速度),并采用模态丢失方案进行训练,使其能够在推理时对缺失模态进行泛化。此外,我们采用扩散策略学习物理基础轨迹的联合条件概率分布和内在可通行性启发式。MAMMOTH利用这一启发式偏好更安全、更平滑的轨迹。我们通过在不同的越野环境中进行广泛的真实机器人实验来验证MAMMOTH,包括夜间操作。我们的结果显示出卓越的性能,在碰撞避免、地形感知规划和对缺失模态的泛化方面有显著改善。用于本研究的代码和数据集将公开发布。

ChunkFlow: Towards Continuity-Consistent Chunked Policy Learning
ChunkFlow:朝着连续一致的分块策略学习
Abstract
Vision-language action (VLA) models increasingly adopt chunked action heads to satisfy real-time constraints; however, this introduces boundary jitter: overlapping regions between consecutive chunks often yield inconsistent predictions, degrading temporal coherence and the task success rate. Existing methods, such as inference-time blending, merely reweight mismatched proposals without correcting underlying errors, leading to residual accumulation under biased or noisy histories. We propose ChunkFlow, a seam-aware training-and-execution framework for chunked policies that aligns chunk structure with boundary execution. It partitions each chunk into frozen, editable, and future zones, applies deterministic overlap blending at execution, and trains raw predictions with seam and first- and second-order continuity losses. History corruption and scheduled sampling improve robustness to executed-history errors, while an AWAC fine-tuning stage adapts the policy without removing these structural regularizers. Under mild smoothness assumptions, pre-blending seam discrepancies provably decay with increasing overlap. Experiments on CALVIN, LIBERO, and real robots show an improved success-stability trade-off with low-latency inference. Project page: https://cytoderm-ai.github.io/chunkflow.

FlowWAM: Optical Flow as a Unified Action Representation for World Action Models
FlowWAM:将光流作为世界动作模型的统一动作表示
Abstract
World Action Models (WAMs) are able to leverage pretrained video generators for both world modeling and action prediction. However, directly leveraging such video generators for control raises a new challenge: how to represent actions in a suitable form that aligns with pretrained video generators while carrying enough motion cues for accurate control. Existing numerical actions fail to satisfy the former, and prior visual action representations overlook the temporal motion structure across frames. We address this issue with FlowWAM, a dual-stream diffusion framework that adopts optical flow as a unified, video-native action representation. Flow videos share the same format as RGB videos and encode rich per-pixel displacement. By jointly modeling them within a shared pretrained video generator, FlowWAM can naturally implement two modes of WAMs. In policy mode, FlowWAM generates flow for action prediction, while in world-model mode, it uses target flow sequences to guide future video generation. Moreover, since flow can be easily extracted from raw videos without action labels, FlowWAM can leverage large-scale action-unlabeled video datasets for pretraining. We empirically find that our flow-based action representation delivers gains across both modes. On RoboTwin manipulation, FlowWAM raises the success rate to 92.94% on the Clean setting and 92.14% on Random, outperforming both VLA and WAM baselines. On WorldArena world modeling, it achieves the best overall EWMScore (63.71) with an 18.4% relative improvement in trajectory accuracy.

DenseReward: Dense Reward Learning via Failure Synthesis for Robotic Manipulation
DenseReward:通过失败合成实现密集奖励学习的机器人操作
Abstract
Reinforcement learning holds great promise for improving robot policies beyond the limits of imitation learning. However, its practical adoption remains bottlenecked by the lack of reliable vision-language reward models that provide dense and informative feedback. Two key challenges remain: acquiring diverse failure data at scale and obtaining fine-grained reward signals beyond sparse trajectory-level success labels. Collecting failure trajectories typically requires laborious human effort, while pseudo-failures constructed by relabeling successful demonstrations fail to capture the diverse physical failure modes that arise during robot execution. Meanwhile, existing reward models often predict sparse binary or trajectory-level rewards, which provide limited guidance for efficient policy optimization. We introduce DenseReward, a dense robotic reward model that addresses both challenges. To train DenseReward, we develop an automated failure data generation pipeline that synthesizes physically realistic failure trajectories in simulation without human labeling, covering diverse failure modes such as collisions, missed grasps, object drops, and recovery behaviors. DenseReward predicts dense frame-level reward scores from visual observations and language instructions, enabling fine-grained estimation of task progress throughout an episode. Experiments show that DenseReward outperforms general-purpose VLMs and existing robotic reward models in dense reward prediction across both simulated and real-world manipulation. We further demonstrate that DenseReward provides effective reward guidance for downstream model predictive control and reinforcement learning. We release the dataset, trained reward models, and evaluation suite to support the development of failure-aware dense reward modeling for robot learning.

TSCA-Net: Temporal-Spatial Clique Attention for Interpretable Multimodal Pedestrian Trajectory Prediction
TSCA-Net:用于可解释的多模态行人轨迹预测的时空团体注意力
Abstract
Accurate pedestrian trajectory prediction in crowded environments remains challenging due to the multimodal uncertainty of human motion and the variable complexity of motion dynamics across different scene contexts. Existing goal-conditioned models rely on static displacement structures that assign equal weight to all historical time steps, standard graph attention mechanisms, and fixed-capacity motion decoders that cannot adapt to local prediction complexity. To address these limitations, we propose TSCA-Net, a trajectory prediction framework built upon three complementary modules. The Temporal-Spatial Clique Attention (TSCA) module introduces learnable temporal gating into clique-based goal-history interaction, enabling time-aware modulation of historical observations relative to each candidate goal. The Cross-Pedestrian Clique Potential (CPCP) module models asymmetric pairwise agent relationships through a dynamic clique potential framework with a time-varying social graph. The Adaptive KAN Grid Refinement (AKGR) mechanism dynamically adjusts the B-spline grid resolution of a Kolmogorov-Arnold Network-augmented LSTM decoder based on per-agent goal distribution entropy, balancing model expressiveness against overfitting across varying motion complexities. Extensive experiments on the ETH/UCY and Stanford Drone Dataset benchmarks demonstrate that TSCA-Net achieves state-of-the-art performance, with average ADE/FDE of 0.13/0.20 m on ETH/UCY and 6.95/10.43 pixels on SDD. Comprehensive ablation studies confirm the complementary contributions of all three proposed modules.

GenDiff: A Dose and Anatomy Aware Diffusion Model with Structural Prior Refinement for Low-Dose CT Reconstruction and Generalization
GenDiff:一种具有结构先验精细化的剂量与解剖学感知扩散模型,用于低剂量CT重建与泛化
Abstract
Computed tomography (CT) is a critical imaging modality for clinical diagnosis, but reducing radiation dose inevitably introduces severe noise and structured artifacts that degrade image quality. Existing deep learning-based low-dose CT (LDCT) reconstruction methods are typically optimized for fixed dose levels or specific anatomical regions, limiting their robustness and generalization in realistic clinical settings. We propose GenDiff, a generalizable diffusion-based framework for LDCT reconstruction that jointly models continuous radiation dose and anatomical information within a unified reconstruction network. The proposed framework integrates a Dose-Anatomy Encoder to learn acquisition-aware embeddings, a dose- and anatomy-conditioned cold diffusion backbone for iterative refinement, a physics-consistency update to enforce fidelity to the CT forward model, and a Structural Prior Refinement Module (SPRM) that preserves anatomical structures while suppressing dose-dependent artifacts. Extensive experiments on multi-anatomy clinical datasets, including unseen ultra-low-dose conditions as well as out-of-distribution phantom and animal datasets, demonstrate that GenDiff consistently outperforms state-of-the-art convolutional neural network and diffusion-based reconstruction methods. The proposed approach achieves superior reconstruction quality while maintaining strong robustness across different dose levels, anatomical regions, and acquisition domains, making it a promising solution for practical low-dose CT imaging.

Anomalous Frame Detection Using VLM-Based Description Comparison for Extracting Expert-Specific Actions and Contextual Decision-Making Scenes with Intra-Video Self-Similarity
基于视觉语言模型(VLM)描述比较的异常帧检测,用于提取专家特定动作和上下文决策场景,结合视频内自相似性
Abstract
Maintenance of critical infrastructures, such as railways and power plants, is essential for ensuring operational safety and reliability. However, the declining number of skilled maintenance workers highlights the need to transfer expert know-how to less experienced workers. Previous studies have attempted to extract candidates of expert knowledge by comparing videos of manual-based work with those of expert workers, mainly focusing on differences in observable actions. However, expert know-how is often embedded not only in actions but also in contextual decision-making during task execution. This paper proposes a method that detects anomalous frames between two task videos to automatically extract candidate scenes containing expert-specific actions and contextual decision-making scenes. The method generates frame-wise visual descriptions using a vision-language model (VLM). Expert-specific actions are extracted based on frame similarities computed from description comparisons between two videos, while contextual decision-making scenes are extracted using segment similarities derived from intra-video self-similarity of the descriptions. In simulated distribution board maintenance experiments involving 27 task scenarios, the proposed method achieved extraction rates of 65% for action candidates and 61% for decision-scene candidates, improving over conventional methods that achieved 59% and 33%, respectively. These results demonstrate the effectiveness of the proposed approach in discovering candidate scenes containing expert know-how.

Abstract
Self-supervised learning offers a compelling approach for medical imaging, where labeled data are scarce and acquisition costs are high. We present COJEPA, a self-supervised framework for volumetric brain MRI that combines a joint-embedding predictive architecture (JEPA) with a contrastive loss (CO), targeting two complementary properties: local predictivity and global discriminability. The model is trained without labels on T1-weighted structural MRI from two cohorts (HCP-YA and AABC, $N{=}2286$, ages 22 to 90), extending I-JEPA to 3D with foreground-aware block masking, a hierarchical convolutional patch embedding, and world-space sinusoidal positional encodings. We evaluate all three objectives across zero-shot twin retrieval, brain tumor segmentation (BraTS 2024), and age regression (OpenBHB). COJEPA achieves the best monozygotic twin recall at rank@1 (0.84), the best finetuning age MAE (2.55 years on OpenBHB 3.0T), and matches CO on BraTS whole-tumor Dice, demonstrating that the combined objective yields representations that are simultaneously discriminative and locally structured.

SpikeDS: Dual Sparsity Spikformer for Perineural Invasion Prediction in 3D MRI
SpikeDS:用于三维MRI中神经周围侵袭预测的双稀疏Spikformer
Abstract
Perineural invasion (PNI) is associated with poor prognosis in cholangiocarcinoma (CCA). However, its detection from 3D MRI remains challenging due to the subtle and spatially heterogeneous imaging signatures at the tumor periphery. Capturing such spatially sparse cues necessitates volumetric analysis of 3D MRI, but existing deep learning approaches incur prohibitive computational costs on volumetric medical images, limiting their clinical deployment. We propose Dual Sparsity Spikformer (SpikeDS), a spiking neural network architecture that jointly exploits activation sparsity from binary spike communication and spatial sparsity from window pruning based on firing rates. SpikeDS introduces Dual Sparsity Spiking Attention (DSSA), which combines two complementary mechanisms. The first is Window-based Expert Mixture Spiking Attention (W-EMSA), which selectively applies attention only to salient windows identified by their firing rates. The second is Cross-Window Spiking Self-Attention (CW-SSA), which enables global context exchange through an asymmetric scheme in which pruned windows still contribute as key-value sources. Evaluated on a clinical cohort of 139 CCA patients via 5-fold cross-validation, SpikeDS achieves an AUC of 0.753 while consuming only 14.4 mJ, surpassing the best baseline in both AUC and energy efficiency. These results suggest that dual sparsity provides an effective hardware-aware strategy for improving the efficiency of 3D spiking transformers without compromising diagnostic performance.

神经周围侵袭(PNI)与胆管癌(CCA)的预后不良相关。然而,由于肿瘤边缘的成像特征微妙且空间异质,从三维MRI中检测PNI仍然具有挑战性。捕捉这种空间稀疏线索需要对三维MRI进行体积分析,但现有的深度学习方法在处理体积医学图像时会产生高昂的计算成本,限制了其临床应用。我们提出了双稀疏Spikformer(SpikeDS),这是一种脉冲神经网络架构,联合利用来自二进制脉冲通信的激活稀疏性和基于发射率的窗口修剪的空间稀疏性。SpikeDS引入了双稀疏脉冲注意力(DSSA),结合了两种互补机制。第一种是基于窗口的专家混合脉冲注意力(W-EMSA),它仅对通过发射率识别的显著窗口选择性地应用注意力。第二种是跨窗口脉冲自注意力(CW-SSA),它通过一种不对称方案实现全局上下文交换,其中修剪的窗口仍然作为键值源进行贡献。在对139名CCA患者的临床队列进行5折交叉验证时,SpikeDS实现了0.753的AUC,同时仅消耗14.4 mJ,超越了在AUC和能效方面的最佳基线。这些结果表明,双稀疏提供了一种有效的硬件感知策略,可以提高三维脉冲变换器的效率,而不影响诊断性能。

Anatomy-Privileged Distillation with Token Routing for MRI-Based Prediction of Perineural Invasion
基于解剖特征的蒸馏与标记路由用于MRI预测神经周围浸润
Abstract
Perineural invasion (PNI) is associated with poor postoperative outcomes in intrahepatic cholangiocarcinoma, but it is confirmed by surgical pathology. Existing preoperative imaging models often rely on radiologist-defined variables, contrast-enhanced imaging, or manual annotations. We propose an anatomy-privileged teacher--student framework for patient-level PNI prediction from T2-weighted MRI. During training, the teacher uses MRI with tumor and liver masks to learn dense token routing, and the student distills this guidance to retain and aggregate informative tokens under a fixed budget. Anatomical supervision is restricted to training, and the deployed model does not require masks at inference. In 155 patients, the proposed method achieved the highest mean AUROC of 0.750 among matched MRI-only baselines evaluated under the same protocol, with 1.43 GFLOPs and 8.02 ms per case on a Jetson Orin Nano Super Developer Kit.

MetaView: Monocular Novel View Synthesis with Scale-Aware Implicit Geometry Priors
MetaView:一种具有尺度感知隐式几何先验的单目新视角合成方法
Abstract
Current visual generation models are capable of producing high-quality content, yet they lack a coherent perception of the spatial structure. Existing generative novel view synthesis methods typically introduce explicit geometry priors, which enforce spatial consistency but inherently restrict generalization in large view changes. In contrast, recent interactive generative methods favor implicit scene modeling, offering greater flexibility at the cost of precise camera control and geometry consistency. In this paper, we propose MetaView, a diffusion-based monocular novel view synthesis framework that enables rendering under large view changes from a single image. Our key insight is to combine implicit geometry modeling with minimal yet essential explicit 3D cues: we incorporate implicit geometry priors from a feed-forward geometry perception network to regularize structure without imposing restrictive reconstruction pipelines, while leveraging metric depth to anchor the generation to a metric scale. This design allows MetaView to achieve both geometry consistency and precise controllability. Extensive experiments demonstrate that, under challenging monocular large viewpoint changes, MetaView significantly outperforms existing methods and exhibits superior generalization. Our code is publicly available at https://github.com/KlingAIResearch/MetaView.

SymbOmni: Evolving Agentic Omni Models via Symbolic Concept Learning
SymbOmni:通过符号概念学习演化的自主全能模型
Abstract
Visual generation is increasingly ubiquitous in diverse domains, from text-to-image/video synthesis to multimodal interactive creation. Yet prevailing monolithic models remain fundamentally constrained by their inability to learn cumulatively and evolve autonomously, which is a limitation we term the "perpetual novice" problem. They lack mechanisms for structuring experience into reusable knowledge and therefore rely on brittle, "from-scratch" reasoning for each task, resulting in poor compositional generalization and inefficient knowledge retention. Motivated by these limitations, we propose SymbOmni, an agentic omni-model designed for cumulative evolution through Symbolic Concept Learning. At its core is the Symbolic Concept Box, an optimizable memory module that abstracts low-level operations into reusable Symbolic Workflow Instructions. SymbOmni operates through an induction-transduction cycle: experiences are abstracted into symbolic concepts (induction), which are then adaptively composed to solve novel tasks (transduction). The training is done by verbalized backpropagation with language-based feedback to enable continuous self-improvement without gradient-based model fine-tuning. Comprehensive experiments validate that (I) SymbOmni significantly outperforms existing agent-based systems for iterative creation and also surpasses closed-source models (e.g., Nano Banana, GPT-Image-1) in both image quality and task success rates; (II) SymbOmni effectively reduces token consumption by over 40% while maintaining competitive generation quality; and (III) SymbOmni enables effective continual learning by achieving cumulative gains across multiple online-learning benchmarks and setting a new state of the art.

视觉生成在各种领域中日益普及,从文本到图像/视频合成到多模态互动创作。然而,现有的单一模型在累积学习和自主演化方面仍然受到根本性限制,这一限制我们称之为“永久新手”问题。它们缺乏将经验结构化为可重用知识的机制,因此在每个任务中依赖脆弱的“从头开始”推理,导致组合泛化能力差和知识保留效率低下。基于这些限制,我们提出了SymbOmni,一种旨在通过符号概念学习实现累积演化的自主全能模型。其核心是符号概念盒(Symbolic Concept Box),一个可优化的记忆模块,将低级操作抽象为可重用的符号工作流指令(Symbolic Workflow Instructions)。SymbOmni通过归纳-传导循环(induction-transduction cycle)运作:经验被抽象为符号概念(归纳),然后被自适应地组合以解决新任务(传导)。训练通过语言反馈的语言化反向传播进行,以实现持续的自我改进,而无需基于梯度的模型微调。全面的实验验证了以下几点:(I)SymbOmni在迭代创作方面显著优于现有的基于智能体的系统,并且在图像质量和任务成功率上超过了封闭源模型(如Nano Banana、GPT-Image-1);(II)SymbOmni有效地将令牌消耗减少了超过40%,同时保持了竞争性的生成质量;(III)SymbOmni通过在多个在线学习基准上实现累积收益,推动了有效的持续学习,并设定了新的最先进水平。

An Empirical Analysis of Continual Learning for Heterogeneous Medical Visual Question Answering
异构医学视觉问答的持续学习实证分析
Abstract
Deploying medical visual question answering (MedVQA) systems in real-world clinical settings requires models that adapt to new clinical tasks without forgetting previously acquired knowledge. Continual learning (CL) provides a practical framework for this setting. Despite rapid progress in medical vision-language models, the behavior of CL methods when training these models across heterogeneous MedVQA tasks remains underexplored. This work presents a systematic evaluation of CL for MedVQA across diverse clinical objectives, including classification, multi-label classification, detection, cell counting, and report generation. Specifically, we explore (1) the ability of existing CL methods to mitigate catastrophic forgetting; (2) their sensitivity to task ordering, analyzing how different task sequences influence performance retention and forgetting; and (3) the evolution of low-rank adaptation parameters as new tasks are learned, revealing patterns of weight drift under different CL methods. Our findings suggest that existing CL methods struggle to maintain stability-plasticity balance when tasks with different objectives and supervision formats are interleaved. Code and full experimental setup will be publicly available.

Representation and Reference Selection in Training-Free Synthetic Image Attribution
无训练合成图像归属中的表征与参考选择
Abstract
Synthetic image attribution aims at identifying the generator responsible for a given AI-generated image. Training-free reference-based attribution methods are easily scalable, since newly emerging generators can be incorporated by adding source-specific references rather than retraining a task-specific classifier. Their performance depends on two coupled factors: the representation space used for comparison and the way source-specific references are constructed. However, the interaction between these two factors remains largely unexplored. In this paper, we provide a controlled analysis of this interaction using references and off-the-shelf pretrained representations. We study representations extracted from different layers of CLIP and DINOv2, along with three reference selection methods with varying semantic constraints: arbitrary, semantically aligned, and resynthesis-based references. Our results show that attribution accuracy consistently peaks at intermediate representation levels, indicating that source-discriminative cues are more accessible before strong semantic abstraction dominates. We further show that intermediate representations are not completely semantically neutral, making reference selection critical: semantically constrained references reduce query-reference mismatch and improve attribution, especially under limited reference budgets. Resynthesis is most useful in low-reference regimes, while semantically aligned references provide a better accuracy-cost trade-off when a moderate-sized reference pool is available. Our findings show that training-free reference-based attribution should be understood as the interaction between where images are compared, how the reference set is constructed, and how many references are available.

Learning from Complementary Ultrasound Representations for Liver Disease Classification
利用互补超声表征进行肝病分类的研究
Abstract
Differentiating non-alcoholic steatohepatitis (NASH) from non-alcoholic fatty liver disease (NAFLD) using ultrasound remains challenging due to subtle tissue alterations and the limited information available in conventional B-mode imaging. In this work, we investigate whether complementary ultrasound representations derived from the same acquisition can improve NASH versus NAFLD classification. Specifically, we combine conventional B-mode ultrasound with physics-guided and local phase-based image representations and evaluate their effectiveness using self-supervised masked autoencoders (MAEs) and graph convolutional networks (GCNs). Experiments were conducted on a multi-site Mayo Clinic cohort consisting of 2,547 liver ultrasound scans from 125 patients. Compared with conventional B-mode ultrasound alone, complementary ultrasound representations consistently improved classification performance, yielding gains of up to 32.4% in accuracy and 91.2% in F1-score. Furthermore, performance improvements were consistently observed across age groups, sex, race, ethnicity,and acquisition sites.

NEEDL-Bench: Dataset for Swiss Needle Cast and Stomata Detection in Microscopy Images
NEEDL-Bench:瑞士针锈病和显微镜图像中气孔检测的数据集
Abstract
We present NEEDL-Bench, a microscopy detection benchmark for Swiss Needle Cast (SNC), a fungal disease of Douglas-fir trees. Douglas-fir is a keystone species of major ecological and economic importance as a softwood timber resource, and SNC affects productivity by forming sexual reproductive structures (pseudothecia) that emerge through the gas exchange pores (stomata) of the needles, thereby blocking gas exchange and compromising needle function. To date, there is no dataset for automatic computer vision detection of these structures, despite computer vision being well poised to standardize and viably scale severity measurements. To address this, we present NEEDL-Bench, a dataset of 3250 annotated images from 1082 Douglas-fir needles, annotated for both keypoints and bounding-box detectors. This dataset exhibits a challenging collection of features, including blur, poor object contrast, small objects of interest, and occlusions. To better capture both the nominal distribution of the data and the full breadth of rare structures, we present two distinct evaluation splits: either random sampling from the collected images or sequential sampling to maximize structural diversity. We evaluate multiple popular keypoint and bounding box methods for detection on this dataset as a baseline and observe a maximum F1 score of 0.8479, suggesting significant potential for gains from future development on this problem. Further, we find that larger models generally do not show commensurate gains in performance on this dataset, indicating that improvements on this problem will not come from scaling laws but rather from domain-specific inductive biases.

Causal Supervision of Attention for Affective Behaviour Analysis
情感行为分析中的因果监督注意力
Abstract
Affective Behaviour Analysis aims to enable machines to infer human affective states from behavioural signals, particularly facial expressions, in real-world environments. The \textit{11th Affective Behaviour Analysis in-the-wild Competition} includes the Multi-Task Learning Challenge based on the s-Aff-Wild2 database, where participants develop a unified framework for Valence-Arousal Estimation, Expression Recognition, and Action Unit Detection. This is challenging because emotion-related cues must be distinguished from spurious factors such as identity, illumination, pose, and demographic variation. Attention mechanisms are well suited as they aggregate information from the most informative facial regions, but may still exploit dataset-specific correlations instead of true affective cues. To improve generalization, we propose an attention pooling framework that promotes subject-invariant attention while increasing feature expressiveness. Our method consists of three components. First, we introduce causal supervision to enforce attention on facial regions with invariant predictive value across subjects. Second, we apply a cross-covariance independence regularization between Key (K) and Value (V) projections to encourage complementary, non-redundant representations. Finally, we replace the linear Value projection with a gated nonlinear SwiGLU transformation to increase feature expressiveness and capture finer-grained affective cues. Our method achieves $CCC_{VA}=0.5123$ for VA estimation on the official validation set, together with $F1_{EX}=0.3116$ and $F1_{AU}=0.3974$ for expression recognition and action unit detection, respectively, resulting in an overall $P$ score (the sum of the individual task metrics) of $1.2214$.

ACZ-GSeg: Adaptive Concentric Zone-based Two-stage Ground Segmentation for LiDAR Point Clouds
ACZ-GSeg:基于自适应同心区的两阶段激光雷达点云地面分割
Abstract
Ground segmentation is a fundamental prerequisite for autonomous navigation, environmental perception, and object detection in ground mobile platforms. To address the under-segmentation of ground points caused by sparse long-range point clouds, ground undulations, and interference from non-ground structures in complex road scenarios, this paper proposes a two-stage ground segmentation method based on the Adaptive Concentric Zone Model. First, an Adaptive Concentric Zone Model is constructed to dynamically determine the number of sectors in each ring, thereby forming local zones with more balanced point distributions. Based on this model, a two-stage ground segmentation method is developed. In the coarse segmentation stage, a lowest-height seed constraint and height-decay weighting are introduced to establish a weighted principal component analysis plane fitting model, from which ground candidate points are extracted. In the fine segmentation stage, a reflectance intensity consistency constraint is employed to distinguish high-confidence ground points from uncertain points, and the uncertain points are further refined based on the local height stability of high-confidence neighborhoods. Experimental results show that the proposed method achieves Precision, Recall, and F1-score values of 99.12%, 96.24%, and 97.66% on the SemanticKITTI dataset, and 98.72%, 100.00%, and 99.36%, respectively, on a self-collected point cloud acquired using a RUBY-PLUS. The results demonstrate that the proposed method can effectively adapt to the range-dependent distribution characteristics of LiDAR point clouds, which are dense at near ranges and sparse at far ranges. It reduces the misclassification of non-ground points while maintaining ground point recall, thereby effectively improving the stability of ground segmentation.

Abstract
Recently, the societal implementation of high-performance image classification models has expanded rapidly. While these models require vast amounts of training data to improve performance, securing sufficient real images is often impractical. As a means to compensate for this shortage, the use of synthetic data is becoming widespread. However, synthetic images are not necessarily equivalent to real images for training purposes. This study systematically analyzes the differences between two types of synthetic images created by different generation methods and real images from three perspectives: high-dimensional feature space, low-level statistics in color space, and the model training process. Furthermore, it experimentally verifies how synthetic data should be utilized by considering realistic data mixing scenarios. This enables the proposal of an evaluation and application strategy for performing preliminary assessments on synthetic images of unknown quality and safely incorporating them into training. This research aims to contribute to enhancing the reliability and safety of image classification models utilizing synthetic images.

Self-Consistent Flow: Unifying Velocity and Endpoint Prediction for Rectified Flow Models
自洽流:统一整流流模型的速度与端点预测
Abstract
In rectified-flow-based generative models, the neural network can be trained to predict two different targets, such as the instantaneous velocity or the data endpoint, to perform denoising. Although prior work shows that these parameterizations lead to different empirical behaviors, the mechanisms underlying their respective advantages remain to be underexplored, and how to combine them effectively is still unclear. In this work, we analyze how learning errors from different parameterizations affect the generation performance. We show that predicting the data endpoint has a clear training signal that stabilizes training, whereas predicting the velocity maintains stable sampling dynamics near the data manifold. Motivated by these insights, we propose Self-Consistent Flow (SC-Flow), a new method that unifies the benefits of both parameterizations. By employing a lightweight consistency loss, SC-Flow jointly trains a single network to predict both the local velocity and the data endpoint, and the consistency between the two predictions improves the model's performance. The method requires no major architectural changes and adds minimal computational overhead. Extensive experiments on image generation tasks demonstrate that SC-Flow substantially stabilizes optimization and improves the straightness of generation paths, leading to significant gains in generation quality over standard rectified-flow baselines.

From Reconstruction to Interpretation: Zero-Setup Multi-Phase Segmentation of X-ray Tomography Data
从重建到解释:零设置多相分割的X射线断层扫描数据
Abstract
X-ray tomography enables nondestructive characterization of material microstructures, while advances in micro-CT imaging have accelerated volumetric data acquisition and reconstruction. However, rapid interpretation remains limited by image segmentation, which often requires manual thresholding, user prompting, or material-specific model training. We present a zero-setup framework for multi-phase segmentation of synchrotron X-ray tomography data that generates interpretable masks for previously unseen datasets without user input or retraining during deployment. The framework combines a material-agnostic mask preparation strategy with a pretrained semantic segmentation network. It represents commonly occurring structural regions as background, sample, bright, dark-gray, light-gray, and porosity masks. Unlike conventional deep learning pipelines that require dataset-specific annotations and retraining, the proposed framework can be applied directly to new scans and produce diagnostic-level segmentations within minutes of reconstruction. This enables rapid assessment of scan quality, sample morphology, porosity, and attenuation variations during ongoing beamline experiments. The generated masks can later be manually refined or used to fine-tune application-specific models when greater accuracy or material-specific labeling is required. Evaluation on held-out synchrotron micro-CT images and qualitative testing on additional datasets demonstrate consistent and physically meaningful segmentations across varying samples and imaging conditions. The framework also substantially outperforms conventional intensity-based thresholding. By connecting high-speed reconstruction with immediate interpretation, the approach supports near-real-time beamline feedback and scalable AI-assisted scientific imaging workflows.

This year's private test, released on a disjoint set of 30 new participants, is scored on five allowed submissions; we report the configuration and rationale of each of our five submissions, and, where already available, the private-test score obtained. Our first submission, an exact replica of the calibrated ensemble tuned only on public validation, scored 0.7361 macro-F1 on the private test, matching our public-test estimate almost exactly and confirming the pipeline generalizes to unseen participants without leakage.

Overview of Cross-Component In-loop Filters in Video Coding Standards
视频编码标准中跨组件环路滤波器的概述
Abstract
In-loop filters have been comprehensively explored during the development of video coding standards due to their remarkable noise-reduction capability. In the early stage of video coding, in-loop filters, such as Deblocking Filter, Sample Adaptive Offset, and Adaptive Loop Filter, were performed separately for each component. Recently, cross-component filters were studied to improve the chroma fidelity by exploiting correlations between the luma and chroma channels. This paper summarizes the cross-component filters used in the state-of-the-art video coding standard. Specifically, it includes the Cross-Component Adaptive Loop Filter and Cross-Component Sample Adaptive Offset. Cross-component filters aim to reduce compression artifacts based on the correlation between different components and provide more accurate pixel reconstruction values. In this paper, we introduce the origin, development, and status of cross-component filters in the current video coding standards. Finally, we had some discussions on the further evolutions of cross-component filters.

在视频编码标准的发展过程中,环路滤波器因其卓越的降噪能力而得到了全面的研究。在视频编码的早期阶段,环路滤波器(如去块滤波器、样本自适应偏移和自适应环路滤波器)是针对每个组件单独执行的。近年来,研究了跨组件滤波器,以利用亮度和色度通道之间的相关性来提高色度保真度。本文总结了当前最先进的视频编码标准中使用的跨组件滤波器,具体包括跨组件自适应环路滤波器(Cross-Component Adaptive Loop Filter)和跨组件样本自适应偏移(Cross-Component Sample Adaptive Offset)。跨组件滤波器旨在基于不同组件之间的相关性减少压缩伪影,并提供更准确的像素重建值。本文介绍了跨组件滤波器在当前视频编码标准中的起源、发展和现状。最后,我们对跨组件滤波器的进一步演变进行了讨论。

RegHead: Non-Humanoid Head Blendshapes via Feed-Forward Registration
RegHead:通过前馈配准构建非类人头部混合形状
Abstract
We present RegHead, a framework for constructing semantic blendshape sets for animatable non-humanoid head avatars. With a fixed expression vocabulary, semantic blendshapes provide a low-dimensional and interpretable animation interface and support cross-identity retargeting. Building such blendshape sets remains expensive because (i) expression-consistent supervision is scarce, (ii) generated 4D assets typically lack correspondence, and (iii) facial motion is highly localized. We propose (1) a large-scale dataset of non-humanoid identities paired with a shared expression vocabulary, obtained by expanding a small artist-rigged library via fine-tuned image editing; (2) a dense stochastic anchor motion representation tailored to localized facial deformations; and (3) a fast feed-forward registration model that converts unregistered expression meshes into a corresponded blendshape basis by predicting anchor-based deformations from the neutral shape. Experiments show that our approach produces higher-fidelity expression meshes than baselines, while running orders of magnitude faster than optimization. We further demonstrate real-time retargeting from human face tracking signals to non-humanoid characters, capturing both head pose and localized facial motions.

Beyond Perfect Priors: Adaptive Gaussian Graph for 4D Driving Reconstruction in the Wild
超越完美先验:用于野外4D驾驶重建的自适应高斯图
Abstract
Reconstructing 4D driving scenes in the wild (e.g., internet and AI-generated videos) is critical for diverse autonomous driving simulation. While recent Gaussian Scene Graph (GSG) methods achieve impressive visual quality, they heavily rely on precise priors, such as accurate camera poses and LiDAR depth, or manual annotations. When initialized with noisy priors estimated from in-the-wild videos, existing GSG methods suffer from optimization ambiguity (e.g., entangling camera and agent poses) and topological failures (e.g., missing objects), causing severe rendering artifacts. To enable robust in-the-wild reconstruction, we introduce Adaptive Gaussian Graph (AGG), a self-correcting 4D framework. Our Semantically-Guided Tick-Tock Strategy leverages 2D foundation features to explicitly decouple static background and camera pose updates from dynamic agent learning. Concurrently, our Adaptive Topology Evolution module actively rectifies graph structures by spawning missing agents, reassigning misclassified Gaussians, and pruning false positives. To rigorously evaluate this in-the-wild setting, we introduce Wild-30, a challenging benchmark of internet and generative videos. Extensive experiments on KITTI and Wild-30 validate that AGG consistently outperforms state-of-the-art approaches in visual fidelity and robustness under noisy priors.

在野外(例如互联网和AI生成的视频)重建4D驾驶场景对于多样化的自动驾驶模拟至关重要。尽管最近的高斯场景图(Gaussian Scene Graph, GSG)方法在视觉质量上取得了令人印象深刻的成果,但它们严重依赖于精确的先验信息,如准确的相机姿态和激光雷达深度,或手动标注。当使用从野外视频中估计的噪声先验进行初始化时,现有的GSG方法会遭遇优化模糊性(例如,相机和代理姿态的纠缠)和拓扑失败(例如,缺失物体),导致严重的渲染伪影。为了实现稳健的野外重建,我们引入了自适应高斯图(Adaptive Gaussian Graph, AGG),这是一种自我修正的4D框架。我们的语义引导滴答策略(Semantically-Guided Tick-Tock Strategy)利用2D基础特征,明确将静态背景和相机姿态更新与动态代理学习解耦。同时,我们的自适应拓扑演化模块通过生成缺失的代理、重新分配错误分类的高斯分布和修剪假阳性,主动修正图结构。为了严格评估这一野外设置,我们引入了Wild-30,这是一个具有挑战性的互联网和生成视频基准。对KITTI和Wild-30的广泛实验验证了AGG在视觉保真度和在噪声先验下的鲁棒性方面始终优于最先进的方法。

The GEST-Engine: From Event Graphs to Synthetic Video. A Full Technical Report
GEST引擎:从事件图到合成视频。完整技术报告
Abstract
We present the GEST-Engine, a complete system that goes from natural-language text to fully-annotated multi-actor video. At its core is an explicit world model: rather than encoding state as a learned latent, the engine maintains a complete, inspectable representation of the world (which actors exist, where they are, what they are doing, which objects they hold, and how events relate in time and space), expressed as a formal Graph of Events in Space and Time (GEST) and realized deterministically inside the open world of a commercial game engine driven through an open-source multiplayer scripting framework. GESTs are produced either procedurally or by an agentic text-to-GEST system in which an LLM Director plans a story through tool calls validated by a programmatic state backend, so every generated specification is executable by construction. A GEST then enters a four-stage execution pipeline: graph parsing and validation, entity and action grounding, temporal orchestration (Allen-style constraints resolved by Floyd-Warshall transitive closure), and execution and capture. In a single simulation pass the engine emits frame-aligned RGB video, dense per-pixel depth, instance segmentation, per-actor skeletal pose, per-frame pairwise spatial-relation graphs, 2D bounding boxes, event-to-frame temporal mappings, and natural-language descriptions, all at zero marginal annotation cost. We further describe an in-game world editor, runtime capability extraction, a text-generation pipeline, and a production system that renders corpora at scale across parallel virtual machines. Because every frame traces back to a semantic specification, the engine guarantees object permanence, multi-actor coordination, and temporal consistency by construction, making its output valuable as training data, evaluation benchmarks, and diagnostic tools for video understanding.

Rough Path Signature-Guided Geometry Augmentation for Few-Shot Industrial Surface Defect Detection
基于粗路径签名引导的几何增强用于少样本工业表面缺陷检测
Abstract
Few-shot industrial defect detection remains difficult for standard supervised detectors, which achieve poor performance on boundary-dominated industrial defects. This paper proposes rough path signature-guided geometry augmentation (RPS-GA), a geometry-aware approach in which Canny edge contours are treated as ordered planar paths whose truncated second-order signature responses, especially the antisymmetric L\'evy-area term, are aggregated into a spatial map that highlights boundary-related structure through two fusion operators, SIG-AUG and SGAA. The approach is evaluated on NEU-DET and PCB-Defect under a few-shot protocol with 5, 10, 20, or 50 labeled images per class, using an unmodified YOLOv8n detector throughout. Compared with the baseline, RPS-GA delivers large gains when supervision is limited, although the margin shrinks as more labels become available. On NEU-DET, SIG-AUG raises 10-shot
[email protected] from 0.341 to 0.583, whereas on PCB-Defect, SGAA improves 10-shot
[email protected] from 0.086 to 0.299 and yields usable detection at 5-shot where the baseline fails entirely. These trends are confirmed by multi-seed evaluation across independent random partitions. Overall, the results indicate that second-order path-signature geometry offers a practical way to strengthen few-shot industrial defect detection without meta-learning or detector redesign.

[email protected]从0.341提高到0.583,而在PCB-Defect上,SGAA将10-shot
[email protected]从0.086提高到0.299,并在5-shot情况下实现可用检测,而基线完全失败。这些趋势通过在独立随机分区上的多种种子评估得到了确认。总体而言,结果表明,二阶路径签名几何提供了一种实用的方法来增强少样本工业缺陷检测,而无需元学习或检测器重设计。

How to Realize Recursively Self-Improving Agents and Personal Singularity: A Goal-, Scope-, Tool-, and Benchmark-Driven Multi-Agent Architecture
如何实现递归自我改进的智能体与个人奇点:一个以目标、范围、工具和基准驱动的多智能体架构
Abstract
Large language model (LLM) agents can increasingly plan, use tools, maintain memory, and execute long-horizon tasks. These advances motivate two linked questions: how can an agent improve the mechanisms by which it learns and acts, and how can that improvement increase the durable capabilities of its user rather than only the software itself? This paper proposes a governed multi-agent architecture for recursively self-improving agents and introduces personal singularity as a bounded human-AI co-development objective: helping a user approach an expanding, user-defined capability frontier across selected domains. Each agent is defined by a goal contract, bounded scope, validated tool registry, tool-level tests, end-to-end benchmarks, an owner-controlled autonomy policy, a routing policy, memory, and an improvement policy. Out-of-scope tasks are transferred to another accountable agent or to a newly created niche agent. A user-facing Auto-Index selects interactive, hybrid, autonomous, or scheduled operation without overriding external permissions. The architecture combines a fast planner-executor-verifier loop, a slower evidence-gated improvement loop, an external governance plane, decentralized agent lineages, an owner-directed agent foundry, and a Personal Singularity OS coordinating working, computational-imaging, process-learning, and personal-learning agents. We formalize scope, routing, improvement acceptance, bounded goal evolution, tool-first execution, and human capability transfer, and provide safety invariants, benchmark design, and an implementation roadmap. This is a position and systems-design paper, not evidence that unrestricted recursive self-improvement or personal singularity has already been achieved.

Auditing Data Leakage in Whole-Slide Image Multimodal Benchmarks
审计全幻灯片图像多模态基准中的数据泄漏
Abstract
Recent vision-language models (VLMs) for computational pathology report striking zero-shot performance on whole-slide image (WSI) visual question answering (VQA) benchmarks. We audit these claims and find them fundamentally compromised by data leakage at two hierarchical levels: patient-level leakage, where slides from the same case appear in both training and test folds, and institutional-level leakage, where different cases nonetheless share staining-batch and scanner signatures through a common Tissue Source Site (TSS). By tracing canonical slide, case, and TSS identifiers across major public resources, we document case level train test overlaps of 92.3~100% on TCGA-derived benchmarks, together with near-complete TSS overlap. We further demonstrate that both leakage levels are linearly decodable from foundation-model feature space, that they induce a measurable accuracy gap between leaked and audit-clean cases on a published checkpoint, and that across multiple published WSI VLMs, peak reported accuracies concentrate on the most heavily contaminated benchmarks. Therefore, the current WSI VQA evaluation cannot distinguish genuine multimodal reasoning from nearest-neighbor retrieval over memorized institutional and patient-specific artifacts. Finally, we outline concrete recommendations for contamination-free evaluation. By addressing benchmark construction, provenance disclosure, and automated overlap auditing, we aim to guide future research toward verifiable claims of progress.

近期的计算病理学视觉-语言模型(VLMs)在全幻灯片图像(WSI)视觉问答(VQA)基准上报告了显著的零样本性能。我们对这些声明进行了审计,发现它们在两个层次上受到数据泄漏的根本性影响:患者级别泄漏,即同一病例的幻灯片出现在训练集和测试集中的情况,以及机构级别泄漏,即不同病例通过共同的组织来源地点(Tissue Source Site, TSS)共享染色批次和扫描仪特征。通过追踪主要公共资源中的标准幻灯片、病例和TSS标识符,我们记录了在基于TCGA的基准上病例级别的训练测试重叠率高达92.3%~100%,并且几乎完全存在TSS重叠。我们进一步证明,这两种泄漏级别可以从基础模型特征空间线性解码,并且它们在发布的检查点上导致了泄漏病例与审计清洁病例之间可测量的准确性差距。此外,在多个发布的WSI VLM中,报告的最高准确率集中在污染最严重的基准上。因此,目前的WSI VQA评估无法区分真正的多模态推理与对记忆中的机构和患者特定伪影的最近邻检索。最后,我们提出了无污染评估的具体建议。通过解决基准构建、来源披露和自动重叠审计,我们旨在引导未来的研究朝着可验证的进展声明迈进。

GeoSEAN: Explainable Country-Level Image Geolocation for ASEAN Regions
GeoSEAN:东盟地区可解释的国家级图像地理定位
Abstract
Image geolocation aims to infer the geographic origin of an image from visual content alone. However, this task remains challenging in regions where countries share similar urban, roadside, architectural, and environmental characteristics. Many existing geolocation models focus on coordinate level prediction or classification performance while providing limited insight into how visual evidence contributes to location predictions. This study presents an explainable country level image geolocation pipeline for 11 ASEAN countries. First, we collected 4,850 images from GeoGuessr style sources, Google Images, and additional street level imagery. We then evaluated three approaches on this dataset: CLIP zero shot classification, a LightGBM classifier, and an MLP classifier. The MLP achieved the best test performance, attaining an accuracy and F1 score of 85.91%. For explainability, predictions generated by the MLP classifier were analyzed post hoc using CLIP attention rollout, YOLO26 object detection on the original images, and Energy Based Pointing Game (EBPG) overlap metrics. Object level analysis indicates that frequently detected objects are not necessarily associated with the highest attention density, suggesting that object frequency and attention based visual evidence capture different aspects of a scene. These results demonstrate that the proposed model can support accurate regional image geolocation while enabling object level inspection of the visual cues underlying its predictions.

Semantic-Edge Response Decoding of SAM3 for Zero-Shot Crack Segmentation
SAM3的语义边缘响应解码用于零-shot裂缝分割
Abstract
Crack segmentation is essential for infrastructure inspection and structural health assessment, but existing high-performance methods typically require task-specific pixel-level annotations and training. Text-promptable vision foundation models enable zero-shot deployment, yet their final mask proposals are poorly suited to thin, fragmented, and low-contrast cracks, whose evidence may be suppressed, truncated, or over-expanded during mask generation. We find that language-conditioned semantic responses within the SAM3 decoder preserve more continuous and complete crack evidence than its final masks. Based on this observation, we propose Semantic-Edge Response Decoding (SERD), which interprets internal responses as a dense crack-likelihood field, calibrates them with a lightweight edge prior, and generates crack masks using a unified global threshold, without annotation or fine-tuning. Experiments on six public datasets show that SERD consistently improves over native SAM3 and outperforms the compared zero-shot and open-vocabulary segmentation methods, achieving an average Crack IoU of 61.14\%, 4.63 points higher than SAM3. Further analyses show that most gains arise from directly decoding internal semantic responses, while edge calibration improves structural recovery and false-positive control without increasing end-to-end inference overhead. These results suggest that, for thin and non-compact targets, internal continuous responses can provide a more transferable interface than the final masks of foundation models.

Adaptive Cross-Modal Fusion with Sparse Attention for Pedestrian Crossing Intention Prediction
基于稀疏注意力的自适应跨模态融合用于行人过马路意图预测
Abstract
Predicting pedestrian crossing intention is a safety-critical task for autonomous driving, yet existing approaches often rely on single-modal inputs or dense multimodal fusion strategies that inadequately capture complementary visual and kinematic information while introducing redundant inter-modal interactions. We propose ADAPT (Adaptive Domain-Aware Pedestrian Crossing Transformer), a multimodal framework that jointly models local and global visual context together with temporal motion dynamics for accurate pedestrian crossing intention prediction. ADAPT processes four spatially aligned visual modalities, including RGB images, local depth maps, global semantic maps, and global depth maps, together with ego-vehicle speed, pedestrian bounding boxes, and skeleton pose information through five specialized modules: a weight-shared Swin Transformer V2 backbone for visual feature extraction, a Cross-Modality Guided Attention module for hierarchical visual fusion, a Mamba-based Motion Feature Encoding module for efficient temporal modeling, a Sparse Cross-Modal Attention module that selectively preserves the most informative inter-modal interactions, and a Vision Transformer-based Temporal Feature Fusion module for sequence-level prediction. Extensive experiments on the JAAD and PIE benchmark datasets demonstrate that ADAPT consistently outperforms existing state-of-the-art methods while maintaining low computational complexity. On JAAD, the proposed method achieves an AUC of 0.73 on JAADbeh and 0.85 on JAADall, while on PIE it achieves an accuracy of 0.92 and an AUC of 0.90. Furthermore, ADAPT performs inference in only 17.23 ms per sample, offering an effective balance between predictive accuracy and real-time deployment efficiency for intelligent transportation and autonomous driving applications.

MobileSAM2: Lightweight Segment Anything for Spatial Intelligence
MobileSAM2:轻量级的空间智能全能分割模型
Abstract
The recent large video foundation model, SAM2, enables segment anything in both images and videos, serving as a powerful base model for various applications. However, many of such use cases require to operate on resource-constrained devices like mobile phones and laptops. In this work, we aim to make SAM2 more mobile-friendly by distilling the heavyweight SAM2 into a lightweight model, facilitating segment anything in both images and videos on mobile devices. To this end, we propose Hypergraphical Knowledge Distill (HyperKD), which introduces the idea of hypergraph into knowledge distillation, aiming to effectively model and transfer SAM2's generalizable and comprehensive knowledge. HyperKD consists of Temporal HyperKD and Granularity HyperKD that construct hypergraphs to explicitly model and extract the generalizable temporal knowledge and the comprehensive multi-granularity knowledge from SAM2 respectively, which are then distilled into the lightweight student model by aligning it with the constructed hypergraphs. Besides, we present MobileSAM2, a new family of lightweight SAM2 that balances efficiency and effectiveness via searching the best model architectures with HyperKD during model size reduction. Extensive experiments validate MobileSAM2 across multiple benchmarks and show promising generalization performance on embodied AI tasks.

What Does a Temporal Benchmark Score Measure? Decomposing Channel Use in Video VLM Evaluation
时间基准分数测量了什么?视频VLM评估中的通道使用解构
Abstract
A score on a temporal video question answering benchmark is meant to measure that a model has temporal understanding, but it conflates two questions. 1. The task question: is the question even temporal, does it need several frames and their order? and 2. The channel question, when it does, does the model recover the order from the pixels, or read it off the positional encoding (RoPE)? Most of a temporal score answers neither, a single frame and answer priors often carry it. The field's validity checks, frame-shuffle sensitivity and the accuracy gained from the full video, speak only to the task question. We contribute a label-free screen for the channel question, the reversal-drop: the accuracy lost when the visual sequence is reversed while RoPE remains forward. It can be applied to compatible temporal benchmarks without new annotations. Paired reverse labels, or tasks whose labels transform deterministically under reversal, distinguish models that follow reversed content from those merely disrupted by the conflict. Molmo2 answers the forward event reading order off positions, while Qwen3-VL answers the reversed event it actually sees, reading visual order (comparatively). We call them position-dominant and visual-sequence-dominant. The split holds across two benchmarks and several temporal tasks at two scales, and activation patching shows it is a real internal property, not an artifact of the conflict.

DM-KG: A Novel Method for Boosting Spatial Cognition of Vision-Language Models in Street View Imagery
DM-KG:一种提升街景图像中视觉-语言模型空间认知的新方法
Abstract
As vision-language models (VLMs) are increasingly deployed in geospatial question answering and visual scene understanding, improving their spatial cognition capability on street view imagery for complex logical reasoning has emerged as a key research priority. However, existing VLMs frequently suffer from "spatial semantic hallucinations" when perceiving object locations, distances, and directions in real-world street view scenes. Furthermore, such errors are often recalcitrant to tracing and calibration, posing a critical bottleneck for their practical deployment in geospatial tasks. To address this pressing challenge, this study proposes DM-KG (Direction-Metric Knowledge Graph), a structurally grounded spatial representation framework for street view imagery. By explicitly extracting directional and metric relationships between entities from a single 2D image, this framework enhances the spatial reasoning accuracy of VLMs through a structured knowledge graph. Specifically, we integrate panoptic segmentation with metric depth estimation to robustly compute entity-level 3D spatial coordinates. Subsequently, we encode the clock azimuths and Euclidean distances of entity pairs into a JSON-formatted knowledge graph, which is injected into the VLM as an explicit geometric prior to guide spatial reasoning. Experimental results on public spatial question-answering (QA) benchmarks demonstrate that DM-KG reduces the mean absolute error (MAE) in distance estimation by 31.1% and the mean angular error in direction judgment by 65.8%, while simultaneously maintaining a high QA success rate. By establishing a complete, augmented reasoning pipeline, this research significantly improves the spatial cognitive capabilities of VLMs in street view scenarios, thereby providing a flexible, generalized, and interpretable framework for geographic visual question answering (GeoVQA) in open environments.

随着视觉-语言模型(VLMs)在地理空间问答和视觉场景理解中的广泛应用,提高其在街景图像中进行复杂逻辑推理的空间认知能力已成为关键研究重点。然而,现有的VLMs在感知真实世界街景场景中的物体位置、距离和方向时,常常遭遇“空间语义幻觉”的问题。此外,这类错误往往难以追踪和校正,成为其在地理空间任务中实际应用的重大瓶颈。为了解决这一紧迫挑战,本研究提出了DM-KG(方向-度量知识图谱),这是一个为街景图像设计的结构化空间表示框架。通过从单张二维图像中显式提取实体之间的方向和度量关系,该框架通过结构化知识图谱增强了VLMs的空间推理准确性。具体而言,我们将全景分割与度量深度估计相结合,稳健地计算实体级的三维空间坐标。随后,我们将实体对的时钟方位角和欧几里得距离编码为JSON格式的知识图谱,并将其作为显式几何先验注入到VLM中,以指导空间推理。在公共空间问答(QA)基准上的实验结果表明,DM-KG将距离估计的平均绝对误差(MAE)降低了31.1%,将方向判断的平均角度误差降低了65.8%,同时保持了较高的问答成功率。通过建立完整的增强推理管道,本研究显著提升了VLMs在街景场景中的空间认知能力,从而为开放环境中的地理视觉问答(GeoVQA)提供了一个灵活、通用且可解释的框架。

ProtoPointNet: Prototype-Based Interpretable Classification of 3D Dental Point Clouds with Verifiable Spatial Activations
ProtoPointNet:基于原型的可解释3D牙科点云分类与可验证空间激活
Abstract
Prototype-based networks provide inherently interpretable classification by linking predictions to learned exemplars, but their use in 3D point clouds and clinical surface-pair reasoning remains limited. We introduce ProtoPointNet, a prototype-based model for dental occlusion classification from registered upper--lower intraoral arch pairs. Each point is encoded by a 14-dimensional descriptor combining local surface geometry, curvature, and explicit inter-arch displacement and clearance, exposing occlusal relationships to prototype matching. A shared multi-task point-cloud backbone learns axis-specific prototype heads for sagittal-left, sagittal-right, vertical, transverse, and midline classification. To support limited clinical data, we train prototypes from scratch using auxiliary supervision and encoder-freeze hand-off. On Bits2Bites, ProtoPointNet achieves mean test macro-F1 of 0.724 and AUROC of 0.825, with strongest performance on vertical (F1 0.828) and sagittal-left classification (F1 0.807). Projected prototype activations localise to anatomically plausible regions, including posterior molars and premolars for cross-bite evidence and anterior incisors for bite-depth evidence. These results support prototype-based reasoning as a transparent, spatially grounded alternative to black-box 3D classifiers for dental surface-pair analysis.

Filtering-out poor-quality images for data preparation
过滤低质量图像以进行数据准备
Abstract
Filtering noise is a fundamental part of data preparation that enhances image quality for applications such as object segmentation, detection, and recognition. Various noise reduction techniques are proposed in the literature, including the use of median, Gaussian, and bilateral filters. Convolutional neural networks (CNNs) have gained popularity in image denoising owing to their ability to extract complex patterns and features from data. CNNs are highly adaptable, making them effective tools for various image-denoising tasks. One drawback of CNN-based techniques is that they require an appropriate training dataset and all images to be resized. Another notable drawback of all these filtering techniques is that they work for certain types of environmental and camera noises. To bridge this research gap, in this paper, for the first time, instead of denoising, we propose an approach that filters out poor-quality images for various environmental and camera impacts. In our approach, quality is assessed using an image quality assessment metric and an optimum threshold is used to filter out poor-quality images. We also ensure that a sufficient number of images remain to develop the deep learning (DL) model. The results produced using real and simulated traffic and object recognition data demonstrate the performance supremacy of the proposed approach compared with the state-of-the-art approaches. The average recognition accuracy for our proposed approach is 93.8% for the traffic sign recognition dataset and 84.9% for the object recognition dataset. This indicates our model's potential for real-life applications such as autonomous vehicles.

ACID: Adaptive Caching for vIDeo generation
ACID:视频生成的自适应缓存
Abstract
Video diffusion models produce high-quality generations but remain slow at inference due to their sequential denoising procedure. Caching-based acceleration methods address this by reusing intermediate model outputs: leading dynamic approaches such as TeaCache, EasyCache, and DiCache accumulate a drift signal and skip expensive model evaluations when accumulated drift stays below a fixed threshold {\tau}. This threshold controls an apparent tradeoff - raising it yields faster generation at the cost of visual quality, while lowering it preserves quality but sacrifices speed. We show this tradeoff is not fundamental; it is an artifact of holding {\tau} constant throughout denoising. We identify the existence of critical steps - timesteps where the drift signal changes rapidly - and show that applying a low threshold selectively at these steps while caching aggressively elsewhere recovers most of the quality of conservative caching at substantially higher inference speeds. Building on this insight, we propose ACID, a lightweight, training-free wrapper that monitors the rate of change of each method's existing drift signal to dynamically switch between a low and a high threshold. ACID is signal-agnostic and modular: it requires no retraining and plugs directly into existing dynamic caching methods without modifying their core mechanisms. Evaluated across three caching methods (TeaCache, EasyCache, DiCache) and three open-source video diffusion models (HunyuanVideo, Wan 2.1, CogVideoX), ACID consistently expands the Pareto frontier of visual quality versus inference speed beyond what any fixed threshold achieves. In particular, on TeaCache and HunyuanVideo, ACID achieves up to 2.16x speedup over the no-caching baseline, and up to 38% additional speedup over the conservative fixed-threshold baseline with negligible (<0.3 dB PSNR, <0.01 SSIM, <0.01 LPIPS) quality degradation.

视频扩散模型能够生成高质量的结果,但由于其顺序去噪过程,推理速度仍然较慢。基于缓存的加速方法通过重用中间模型输出来解决这一问题:领先的动态方法如 TeaCache、EasyCache 和 DiCache 在累积漂移信号时跳过昂贵的模型评估,当累积漂移保持在固定阈值 { au} 以下时。这一阈值控制着一种明显的权衡——提高阈值可以加快生成速度,但会牺牲视觉质量,而降低阈值则能保持质量,但会牺牲速度。我们表明,这种权衡并不是根本性的;它是由于在去噪过程中保持 { au} 不变所造成的伪影。我们识别出关键步骤的存在——漂移信号快速变化的时间步,并展示在这些步骤上选择性地应用低阈值,同时在其他地方积极缓存,可以在显著更高的推理速度下恢复大部分保守缓存的质量。基于这一见解,我们提出了 ACID,一种轻量级的、无训练的封装器,监测每种方法现有漂移信号的变化速率,以动态切换低阈值和高阈值。ACID 是信号无关的和模块化的:它无需重新训练,并且可以直接插入现有的动态缓存方法,而无需修改其核心机制。在三个缓存方法(TeaCache、EasyCache、DiCache)和三个开源视频扩散模型(HunyuanVideo、Wan 2.1、CogVideoX)上的评估表明,ACID 一致地扩展了视觉质量与推理速度之间的帕累托前沿,超出了任何固定阈值所能实现的范围。特别是在 TeaCache 和 HunyuanVideo 上,ACID 实现了相较于无缓存基线高达 2.16 倍的加速,并在保守固定阈值基线之上实现了高达 38% 的额外加速,同时质量下降微乎其微(<0.3 dB PSNR,<0.01 SSIM,<0.01 LPIPS)。

Implicit 4D Gaussian Splatting for Fast Motion with Large Inter-Frame Displacements
隐式四维高斯点云快速运动与大帧间位移的处理
Abstract
Recent 4D Gaussian Splatting (4DGS) methods often fail under fast motion with large inter-frame displacements, where Gaussian attributes are poorly learned during training, and fast-moving objects are often lost from the reconstruction. In this work, we introduce Spatiotemporal Position Implicit Network for 4DGS, coined SPIN-4DGS, which learns Gaussian attributes from explicitly collected spatiotemporal positions rather than modeling temporal displacements, thereby enabling more faithful splatting under fast motions with large inter-frame displacements. To avoid the heavy memory overhead of explicitly optimizing attributes across all spatiotemporal positions, we instead predict them with a lightweight feed-forward network trained under a rasterization-based reconstruction loss. Consequently, SPIN-4DGS learns shared representations across Gaussians, effectively capturing spatiotemporal consistency and enabling stable high-quality Gaussian splatting even under challenging motions. Across extensive experiments, SPIN-4DGS consistently achieves higher fidelity under large displacements, with clear improvements in PSNR and SSIM on challenging sports scenes from the CMU Panoptic dataset. For example, SPIN-4DGS notably outperforms the strongest baseline, D3DGS, by achieving +1.83 higher PSNR on the Basketball scene.

Lost in Visual Translation: A VLM-Assisted Perceptual-Semantic Coherence Framework for EEG-to-Image Reconstruction
迷失在视觉翻译中:一种基于视觉语言模型的感知-语义一致性框架用于脑电图到图像重建
Abstract
EEG-to-image evaluation should distinguish visual fidelity from recoverable meaning. Yet EEG-derived reconstructions are blurry, distorted, and low-detail, causing SSIM, LPIPS, and CLIP to penalize semantically recoverable outputs or reward plausible but incorrect ones. We analyze 6,855 ground-truth/reconstruction pairs from ATM, ENIGMA, BrainVis, and DreamDiffusion using semantic probes, caption harshness and blind-spot rates, and controlled degradations. Pixel metrics show near-zero correlation with semantic consistency, while representation metrics conflate perceptual and semantic errors. We therefore introduce a BCI-aware framework in which four VLMs assess image pairs through structured questions, producing Tolerant Perceptual Alignment Scores (T-PAS) and Tolerant Semantic Alignment Scores (T-SAS). Their consensus is distilled into the BCI-Coherence Score (BCS), a compact evaluator achieving a T-PAS MAE of 0.079 (r = 0.700) and a T-SAS MAE of 0.082 (r = 0.850) on our data. Human validation shows highly reliable joint coherence judgments, with Cohen's kappa = 0.882 +/- 0.174 and Krippendorff's alpha = 0.882, supporting perceptual-semantic recoverability over generic visual similarity.

UMSS: Towards Unsupervised Multi-modal Semantic Segmentation
UMSS:面向无监督多模态语义分割
Abstract
Multimodal semantic segmentation (MSS) is essential for robust perception in complex environments, yet its potential remains largely untapped because of the prohibitive cost of human annotations. While unsupervised semantic segmentation (USS) has achieved strong results on a single RGB modality, its naive extension to multimodal data is often hindered by fusion degradation. This occurs because, without explicit supervision, existing frameworks struggle to reconcile the heterogeneous structural patterns captured by different sensors and therefore fail to effectively exploit their complementary information. In this paper, we make the first attempt to address the novel problem of Unsupervised Multimodal Semantic Segmentation (UMSS), aiming to effectively exploit complementary sensor information in a fully label free setting. To this end, we propose UniM2 (Unified Multimodal), a novel framework built on DINOv3 that transforms conventional fusion methods into consistent performance gains. Our key idea is to learn a unified latent space driven by Cross Modal Correspondence Synergy (CMCS) to extract intrinsic shared semantic cues, bypassing the need for label guided adaptive fusion. To mitigate inherent intermodal conflicts, we introduce a Cross Modal Harmonizer (CMH) that designates RGB as a stable reference, effectively suppressing inconsistent relational supervision while guiding the model to exploit complementary structural features. Extensive experimental results on NYU Depth v2 and MFNet show that UniM2 improves mIoU by 6.4% and 9.8%, respectively, demonstrating clear advantages over existing frameworks for UMSS.

多模态语义分割(MSS)对于在复杂环境中实现稳健感知至关重要,但由于人工标注的高昂成本,其潜力仍未得到充分挖掘。尽管无监督语义分割(USS)在单一RGB模态上取得了良好的结果,但其在多模态数据上的简单扩展常常受到融合降级的阻碍。这是因为在没有明确监督的情况下,现有框架难以调和不同传感器捕获的异质结构模式,因此未能有效利用其互补信息。本文首次尝试解决无监督多模态语义分割(UMSS)的新问题,旨在在完全无标签的环境中有效利用互补传感器信息。为此,我们提出了UniM2(统一多模态),这是一个基于DINOv3构建的新框架,将传统的融合方法转变为一致的性能提升。我们的关键思想是通过跨模态对应协同(CMCS)学习一个统一的潜在空间,以提取内在共享的语义线索,从而绕过标签引导的自适应融合需求。为了缓解固有的模态间冲突,我们引入了跨模态协调器(CMH),将RGB指定为稳定参考,有效抑制不一致的关系监督,同时引导模型利用互补的结构特征。在NYU Depth v2和MFNet上的大量实验结果表明,UniM2分别提高了mIoU 6.4%和9.8%,展示了其在UMSS领域相较于现有框架的明显优势。

IQA-T1: Tool-based Visual Evidence Reasoning for Image Quality Assessment
IQA-T1:基于工具的视觉证据推理用于图像质量评估
Abstract
Image Quality Assessment (IQA) in open-world environments remains challenging due to limited generalization and interpretability. Recent approaches based on multimodal large language models (MLLMs) introduce textual reasoning for quality prediction, yet their judgments rely heavily on semantically biased internal representations, making them insensitive to low-level perceptual degradations. We propose IQA-T1, a tool-based visual evidence reasoning framework that augments MLLM reasoning with explicit perceptual observations. During inference, the model autonomously invokes specialized analysis tools to generate structured visual evidence, such as noise residual maps, gradient statistics, and frequency spectra, which are progressively integrated into the reasoning process. To support this paradigm, we construct Q-Tool, a dataset containing 11k multimodal reasoning chains grounded in tool-generated evidence. Extensive experiments on seven IQA benchmarks show that IQA-T1 achieves the best overall performance across datasets while producing interpretable and evidence-grounded quality assessments. Code and dataset are available at https://github.com/zibuyu-02/IQA-T1.

Demonstration of the common dual-channel feature decoupling characteristic of front-door mediation causal inference methods in whole-slice image classification
前门干预因果推断方法在全切片图像分类中的共同双通道特征解耦特性展示
Abstract
Causal inference using front door intervention and multi-instance learning (MIL) has advanced the analysis of Whole Slide Images (WSI) in digital pathology. These methods adjust feature distributions of subtle evidence sub-images to correctly associate them with WSI-level diagnoses. We propose and prove 2 hypotheses for evaluating such methods: 1) Causal inference MIL introduces an independent classification channel that effectively completes WSI classification; 2) Greater difference between features extracted by the new and baseline channels increases effectiveness in eliminating false correlations. This hypothesis describes the core of causal inference MILs: overlaying parallel, independent channels to eliminate false associations between WSI-level diagnostic and non-diagnostic evidence sub-images by increasing deep feature diversity. Based on these hypotheses, we evaluated several causal inference MILs on breast cancer and non-small cell lung cancer datasets. This hypothesis provides a new theoretical perspective for applying causal inference to WSI analysis.

SeamGen: Artist-Aligned UV Seam Generation via Graph Flow Matching
SeamGen:通过图流匹配实现艺术家对齐的UV接缝生成
Abstract
UV seam placement is a critical yet labor-intensive step in 3D content creation, requiring artists to balance chart shape, seam concealment, and alignment with semantic and geometric features. Existing automatic methods are primarily based on per-object optimization, relying on handcrafted objectives to avoid distortion or on proxies from pretrained models to inject semantic information. However, these strategies are not always well aligned with seams used in industrial production pipelines, often resulting in layouts that deviate from artist-preferred seam patterns and practical production requirements. To address these limitations, we propose SeamGen, a generative model for UV seam generation that aligns with artist preferences and production requirements. Instead of depending on manually designed objectives and constraints, SeamGen learns the distribution of per-edge seam labels from a large corpus of existing seam layouts using a flow-matching generative model. A key challenge is that typical Transformer architectures used in flow matching models are designed for sequential representations, such as point clouds, and cannot naturally account for mesh topology. To enable mesh-native learning, we design a Mesh Transformer backbone that interleaves local graph attention over mesh edges with global self-attention across vertices, capturing both fine-grained geometric cues and long-range topological coherence. To further improve inference-time controllability and quality, we exploit the training-free inpainting capability of flow models for both localized seam refinement and constraint-guided seam generation. Extensive experiments show that by learning priors from professional seam layout data, SeamGen produces UV layouts that better align with artist-authored preferences and achieve superior perceptual quality compared with distortion-based and semantic-proxy baselines.

Seeing Globally, Refining Locally: Global Visual Guidance and Local Ultrasound Cues for Robust Freehand 3-D Ultrasound Reconstruction
全球视野,局部精炼:全球视觉引导与局部超声线索结合的稳健自由手3D超声重建
Abstract
Freehand 3-D ultrasound (US) imaging has attracted increasing attention owing to its intuitive volumetric visualization, ease of use, and low cost. However, accurate 3-D reconstruction critically depends on stable probe pose estimation, yet existing trackerless methods remain susceptible to accumulated pose errors, particularly over long scanning trajectories. To address this limitation, we propose a global-to-local pose estimation framework that exploits external camera observations for globally stable localization and B-mode US images for anatomy-aware local refinement. Specifically, the framework comprises a dual-camera branch that performs contextual feature aggregation across camera views and temporal observations to estimate a globally consistent probe trajectory, and a B-mode branch that performs anatomical feature aggregation from sequential US images to capture tissue-dependent local motion cues. A cross-modal fusion module subsequently integrates the contextual camera features and anatomical US features to predict pose residuals and refine the camera-derived estimates in the transformation space. Furthermore, a multi-scale pose loss constrains relative motion over multiple temporal horizons to suppress accumulated drift during extended scans. The proposed framework is validated on phantom and in vivo datasets. On two in-house datasets (FUSION-J and FUSION-L) collected using different machines, the proposed US + Dual-Cam model reduces average trajectory drift to 1.67 mm and 1.29 mm, representing improvement of 16.50% and 27.12%, respectively, over a strong dual-camera baseline, while substantially outperforming US-only pose estimation (>13 mm drift). In in vivo forearm arteries reconstruction, it achieves Hausdorff distances of 1.58 mm, demonstrating the effectiveness of the proposed method on real clinical scenarios.

Abstract
Objective: Radiomic texture features are usually computed in voxel-index neighborhoods, implicitly assuming isotropic spatial relationships. In anisotropic images, this can confound voxel geometry with interpolation-induced signal changes. We developed a voxel-spacing-aware radiomic framework that incorporates physical geometry into texture computation without resampling. Approach: We modified PyRadiomics to account for voxel spacing while preserving the native image signal. Four configurations were compared: native non-resampled extraction (NR), isotropic resampling (RS), voxel-spacing-aware extraction (VS), and fake-isotropic preprocessing (FK), in which spacing metadata were overwritten without altering the image array. Experiments included 685 LIDC-IDRI pulmonary nodules and 209 I-SPY2 breast MRI cases, with 196 radiomic descriptors. Robustness was assessed using ICC, within-subject variability, Friedman testing, feature selection, machine learning, a multilayer perceptron, and external validation. Main results: VS showed near-native agreement with NR: median ICC(A,1) was 0.9976 in CT and 0.9984 in MRI. RS produced lower agreement and larger deviations, while FK showed intermediate behavior, confirming that spacing metadata alone can affect radiomic features. Gradient-derived and neighborhood-sensitive descriptors were most affected by preprocessing. VS preserved predictive performance comparable to NR in external CT validation, whereas MRI showed greater variability across preprocessing strategies and classifiers. Significance: Voxel-spacing-aware extraction separates geometric modeling from interpolation-induced signal modification while preserving the native image signal, offering a coherent alternative to isotropic resampling for radiomic analysis of anisotropic CT and MRI.

目的:放射组学纹理特征通常在体素索引邻域中计算,隐含假设各向同性空间关系。在非各向同性图像中,这可能会将体素几何与插值引起的信号变化混淆。我们开发了一种体素间距感知的放射组学框架,能够在不重新采样的情况下将物理几何纳入纹理计算。方法:我们修改了PyRadiomics,以考虑体素间距,同时保留原始图像信号。比较了四种配置:原始非重采样提取(NR)、各向同性重采样(RS)、体素间距感知提取(VS)和伪各向同性预处理(FK),其中间距元数据被覆盖而不改变图像数组。实验包括685个LIDC-IDRI肺结节和209个I-SPY2乳腺MRI案例,共196个放射组学描述符。通过ICC、组内变异性、Friedman检验、特征选择、机器学习、多层感知器和外部验证评估了稳健性。主要结果:VS与NR显示出接近原始的一致性:CT中中位ICC(A,1)为0.9976,MRI中为0.9984。RS产生了较低的一致性和更大的偏差,而FK显示出中间行为,确认仅凭间距元数据就可以影响放射组学特征。梯度导出和邻域敏感描述符受到预处理的影响最大。VS在外部CT验证中保留了与NR相当的预测性能,而MRI在不同预处理策略和分类器之间显示出更大的变异性。意义:体素间距感知提取将几何建模与插值引起的信号修改分离,同时保留原始图像信号,为非各向同性CT和MRI的放射组学分析提供了一种一致的替代方案,以取代各向同性重采样。

Contrastive-Augmented Flow Matching for Style-Content Disentanglement
对比增强流匹配用于风格-内容解耦
Abstract
Learning representations that separate content and style is crucial for controllable generation and compositional generalization. However, diffusion and flow-based models trained primarily with generative objectives often produce entangled or misaligned factors. To address this gap, we introduce Contrastive Augmented Flow Matching (CAtFM), a framework that integrates contrastive regularization into an invertible flow matching formulation to promote structured content-style representations. Rather than constraining intermediate latents or velocity fields, we apply contrastive supervision to predicted endpoints during training, enforcing semantic consistency across transported distributions while allowing disentanglement to emerge implicitly, without assuming strictly pure or fully factorized content and style representations. Our main experiments operate in the CLIP embedding space, with additional validation using frozen DINO and ALIGN encoders. Across synthetic data, in-domain styles, and real-world benchmarks (ImageNet, WikiArt, DomainNet, and DTD), CAtFM improves content and style retrieval, enhances embedding cluster separation, and achieves stronger open-set robustness compared to generative and discriminative baselines. Overall, CAtFM provides a simple way to couple discriminative constraints with deterministic transport, improving disentanglement and robustness under distribution shift.

Virtual Chromoendscopy with Tunable Visibility Enhancement
可调可见性增强的虚拟染色内镜技术
Abstract
Chromoendoscopy (CE) is a common clinical practice that sprays indigo carmine blue dye onto the gastric surface to improve the visibility of gastric lesions, such as an early cancer. While CE is effective in detecting the lesions, preparing and spraying the dye needs additional cost and time, which is undesirable both for patients and medical practitioners. To overcome this issue, virtual chromoendoscopy (V-CE) was recently proposed, which applies a learned image translation model to virtually generate a CE image from a standard endoscopy (SE) image. In this paper, we propose virtual enhanced chromoendoscopy (V-ECE) that combines V-CE with image enhancement techniques to further improve the visibility of gastric lesions. Because a desired enhancement level depends on the inspected lesion and the practitioner's preference, we introduce a novel image translation model that can generate V-ECE images using an enhancement level tunable by a user. Experimental results demonstrate that our proposed model can plausibly generate V-ECE images with various enhancement levels using a unified model.

MQAdapter: Multi-Modal Quantum Adapter for Coarse-to-Fine VLM Fine-tuning
MQAdapter:用于粗到细的多模态量子适配器在视觉语言模型微调中的应用
Abstract
Large-scale Vision-Language Models have demonstrated impressive transfer learning capabilities across a wide range of tasks. For few-shot classification, we observe that VLMs exhibit a notable ability to filter candidate categories and thus achieve high Top-K accuracy. However, they often struggle with fine-grained discrimination among visually similar categories, resulting in unsatisfactory Top-1 performance, as shown in Figure 1. Existing studies on VLM adapters generally focus on global alignment between visual and textual representations in the feature space, but fail to exploit semantically similar categories to refine fine-grained visual representations. Based on these observations, we propose a novel coarse-to-fine VLM fine-tuning approach for few-shot learning that leverages quantum computation, termed the Multi-Modal Quantum Adapter (MQAdapter). Specifically, MQAdapter first retrieves the Top-K category candidates most similar to the input image and uses them as semantic anchors. It then employs a cross-modal quantum learning mechanism to refine visual features under the guidance of these anchors. The core of this mechanism is the encoding of visual and textual features into quantum states. By leveraging quantum entanglement and superposition in a high-dimensional Hilbert space, MQAdapter effectively models higher-order cross-modal interactions, producing more discriminative representations than traditional Euclidean adapters. MQAdapter is parameter-efficient and can be integrated with various existing fine-tuning algorithms to achieve further performance gains. Evaluations on 15 datasets demonstrate the effectiveness of MQAdapter while requiring fewer trainable parameters.

大规模视觉-语言模型在广泛任务中展示了令人印象深刻的迁移学习能力。在少样本分类中,我们观察到视觉语言模型(VLMs)具有显著的候选类别过滤能力,从而实现高Top-K准确率。然而,它们在视觉上相似类别之间的细粒度区分上常常表现不佳,导致Top-1性能不理想,如图1所示。现有关于VLM适配器的研究通常集中在视觉和文本表示在特征空间中的全局对齐,但未能利用语义相似的类别来细化细粒度的视觉表示。基于这些观察,我们提出了一种新颖的粗到细的VLM微调方法,适用于少样本学习,该方法利用量子计算,称为多模态量子适配器(MQAdapter)。具体而言,MQAdapter首先检索与输入图像最相似的Top-K类别候选,并将其作为语义锚点。然后,它采用跨模态量子学习机制,在这些锚点的指导下细化视觉特征。该机制的核心是将视觉和文本特征编码为量子态。通过利用高维希尔伯特空间中的量子纠缠和叠加,MQAdapter有效地建模更高阶的跨模态交互,生成比传统欧几里得适配器更具辨别力的表示。MQAdapter在参数效率上表现优越,并且可以与多种现有微调算法集成,以实现进一步的性能提升。在15个数据集上的评估证明了MQAdapter的有效性,同时所需的可训练参数更少。

DeGuNet: Depth-Guided Ultra-Compact Backbones for Efficient LiDAR-Camera 3D Detection
DeGuNet:用于高效LiDAR-相机3D检测的深度引导超紧凑骨干网络
Abstract
In autonomous driving perception, the fusion of LiDAR and camera modalities has become the dominant paradigm for 3D object detection. However, current multi-modal frameworks heavily rely on massive visual backbones pretrained on 2D semantic tasks. This reliance introduces substantial parameter redundancy and a structural misalignment, as 2D priors are ill-equipped to handle the extreme sparsity of LiDAR projections required for Bird's-Eye-View geometry. To address this, we present DeGuNet, an ultra-compact and plug-and-play image backbone explicitly designed for depth-guided representation learning. By incorporating sparsity-aware feature extraction mechanisms, DeGuNet effectively aligns multi-view images with unstructured LiDAR depth while strictly preventing invalid-region contamination. Extensive experiments on the nuScenes dataset demonstrate DeGuNet's broad plug-and-play applicability and superior efficiency. When integrated into established baselines, it fundamentally eliminates architectural redundancy, reducing GPU memory consumption by up to 66.5% and achieving a 1.16x inference speedup. Concurrently, DeGuNet delivers up to a 6.20 absolute mAP gain, establishing a new paradigm for parameter-efficient multi-modal 3D perception.

More Than Where You Are: Learning Semantics, Structure, and Geometry from Cross-View Localization
超越位置:从跨视角定位中学习语义、结构和几何
Abstract
Consistent cross-view understanding under extreme viewpoint changes is essential for spatial intelligence, as it enables models to recognize the same scene across extreme viewpoint gaps. Cross-view localization naturally provides a promising pathway toward this ability, as it requires a model to align ground-view imagery with geo-referenced satellite-view imagery despite drastic appearance changes to estimate camera poses. Recent visual foundation models have made this long-standing localization problem increasingly feasible by providing rich 2D representations for cross-view matching. However, we argue that cross-view localization should not be viewed merely as 2D matching or pose estimation. In this work, we revisit cross-view localization as more than pose estimation and investigate how it can help the model develop consistent cross-view understanding under extreme viewpoint changes, including stable semantics, reliable structure, and transferable geometry. We identify three key limitations of existing methods that prevent them from achieving this. They usually lack explicit 3D grounding, rely on strict point-wise matching that can weaken semantic consistency, and learn from an absolute objective that provides limited guidance for geometric reasoning. To address these limitations, we propose CROSS, a unified cross-view localization framework built upon 3D-grounded alignment, structure-aware matching, and hypothesis ranking. This formulation makes structure learning an intrinsic requirement, encourages semantic representations to remain stable, and enables the model to acquire transferable geometry. Extensive experiments on the KITTI and VIGOR datasets show that CROSS achieves state-of-the-art performance in cross-view localization. More importantly, CROSS effectively learns stable semantics, reliable structure, and transferable geometry across extremely different viewpoints.

在极端视角变化下保持一致的跨视角理解对于空间智能至关重要,因为它使模型能够在极端视角差异中识别相同的场景。跨视角定位自然为这一能力提供了一个有前景的途径,因为它要求模型对齐地面视图图像与地理参考的卫星视图图像,尽管外观发生了剧烈变化,以估计相机姿态。最近的视觉基础模型通过为跨视角匹配提供丰富的二维表示,使这一长期存在的定位问题变得越来越可行。然而,我们认为跨视角定位不应仅仅被视为二维匹配或姿态估计。在本研究中,我们重新审视跨视角定位,认为它不仅仅是姿态估计,并探讨它如何帮助模型在极端视角变化下发展一致的跨视角理解,包括稳定的语义、可靠的结构和可转移的几何。我们识别出现有方法的三个关键局限性,这些局限性阻止它们实现这一目标。它们通常缺乏明确的三维基础,依赖严格的逐点匹配,这可能削弱语义一致性,并从一个提供有限几何推理指导的绝对目标中学习。为了解决这些局限性,我们提出了CROSS,一个基于三维基础对齐、结构感知匹配和假设排名的统一跨视角定位框架。这种表述使结构学习成为内在要求,鼓励语义表示保持稳定,并使模型能够获取可转移的几何。在KITTI和VIGOR数据集上的大量实验表明,CROSS在跨视角定位中实现了最先进的性能。更重要的是,CROSS有效地学习了在极其不同的视角下稳定的语义、可靠的结构和可转移的几何。

ARDepth: Auto-regressive Monocular Depth Estimation with Progressive Visual Conditioning
ARDepth:具有渐进视觉条件的自回归单目深度估计
Abstract
Diffusion models have recently become the dominant paradigm for monocular depth estimation (MDE). However, they implicitly assume that depth can be recovered as a globally smooth field through iterative denoising, which does not explicitly reflect the piecewise and scale-dependent organization of scene geometry. In practice, geometric structure emerges progressively across spatial scales, where coarse layout, surfaces, and boundaries are constructed in a hierarchical manner. Motivated by this observation, we introduce ARDepth, which formulates depth estimation as structured auto-regressive generation. Instead of recovering depth through global refinement, ARDepth progressively constructs depth representations as spatial resolution increases. To support this generative process, we introduce Scale-Progressive Conditioning (SPC) to inject multi-scale visual features at each generation stage, and Semantic-Aware Guidance (SAG) to provide scene-level semantic priors that enhance global structural consistency. Together, these designs enable the model to capture fine-grained local details while maintaining coherent global geometry. Empirical results demonstrate that our approach achieves strong performance and produces structurally consistent depth predictions across scales, validating auto-regressive generation as a promising alternative paradigm for geometric modeling.

扩散模型最近已成为单目深度估计(MDE)的主导范式。然而,它们隐含地假设深度可以通过迭代去噪恢复为一个全局平滑的场,这并未明确反映场景几何的分段和尺度依赖组织。在实践中,几何结构在空间尺度上逐渐显现,其中粗略布局、表面和边界以层次化的方式构建。基于这一观察,我们提出了ARDepth,它将深度估计公式化为结构化的自回归生成。ARDepth不是通过全局细化来恢复深度,而是随着空间分辨率的增加逐步构建深度表示。为了支持这一生成过程,我们引入了尺度渐进条件(Scale-Progressive Conditioning, SPC),在每个生成阶段注入多尺度视觉特征,并引入语义感知引导(Semantic-Aware Guidance, SAG),提供增强全局结构一致性的场景级语义先验。这些设计共同使模型能够捕捉细致的局部细节,同时保持一致的全局几何结构。实证结果表明,我们的方法在各尺度上实现了强大的性能,并产生了结构一致的深度预测,验证了自回归生成作为几何建模的有前景的替代范式。

Let RGB Be the Language of Vision
让RGB成为视觉的语言
Abstract
This work introduces a unified formulation for vision models, where diverse forms of visual information beyond natural images, such as masks, depth maps, and other structured visual signals, are all represented as RGB images, while general visual tasks can be converted into a common RGB-to-RGB image editing problem. In this paradigm, different types of visual information internally share the same encoding and decoding architecture and parameters as natural images, enabling a single model to transfer across tasks through a unified visual interface, in a way analogous to how language models operate over text. We refer to this formulation as RGB In and RGB Out (RINO). Built upon a generic image editing backbone without task-specific fine-tuning, RINO demonstrates robust and competitive zero-shot performance on both dense understanding tasks such as segmentation and depth estimation (where we unify outputs as RGB), and dense-conditioned generation tasks such as pose-to-image generation (where we unify inputs as RGB). We hope this study provides useful insights toward general unified vision-language systems, where diverse visual tasks can be expressed, interpreted, and solved through a shared visual language.

Steering Diffusion Models via Class-Contrastive Influence for Few-Shot Medical Classification
通过类对比影响引导扩散模型进行少样本医学分类
Abstract
When labeled data are scarce, off-the-shelf diffusion models can augment training sets for few-shot medical image classification, but not all generated samples are equally useful for the downstream task. Existing approaches largely improve synthetic data by increasing realism, diversity, or domain adaptation, while overlooking a more fundamental question: how should sample usefulness for classification be measured and optimized? We address this with Class-Contrastive Influence (C2I), a criterion that quantifies a sample's usefulness through its gradient-based influence on the classifier. We find that effective samples exhibit a strong C2I gap: their loss gradients align with validation gradients from the same class and oppose those from other classes. Our analysis further suggests that such high-C2I samples are hard, boundary-proximal examples that help refine the decision boundary and improve robustness. Building on this insight, we fine-tune diffusion models with reinforcement learning using a C2I-based reward to steer generation toward class-informative samples. Across several few-shot medical imaging benchmarks, C2I-guided generation improves downstream accuracy and robustness over diffusion-based augmentation baselines, showing that synthetic augmentation is most effective when guided by task usefulness rather than image quality alone.

Self in Space: Benchmarking Self-Awareness and Spatial Cognition in UAV Embodied Intelligence
空间中的自我:无人机具身智能的自我意识与空间认知基准测试
Abstract
Autonomous UAV systems increasingly rely on multimodal large language models (MLLMs) to operate in complex real-world environments. Such embodied scenarios require not only understanding the surrounding space but also maintaining a coherent representation of the agent itself. However, existing UAV-oriented approaches and benchmarks remain largely environment-centric, primarily focusing on spatial understanding tasks, with the agent's self-awareness remaining implicit. To address this gap, we introduce SIS-Bench, a benchmark for evaluating embodied spatial intelligence in UAV scenarios under a unified self-in-space formulation. SIS-Bench organizes evaluation along two complementary dimensions, space and self, and a three-level hierarchy of perception, memory, and reasoning. It contains 4,856 question--answer pairs across 13 tasks derived from 1,646 real-world UAV videos through a task-conditioned construction pipeline with expert verification.Extensive evaluations reveal that current MLLMs exhibit fundamental limitations in modeling dynamic and agent-centered processes. In particular, we observe a clear imbalance between spatial cognition and self-awareness, as well as a progressive performance degradation across cognitive levels.Motivated by these findings, we further explore a motion-aware representation that incorporates self-related dynamics through optical flow and visual feature fusion. Experimental results show that modeling agent motion consistently improves perception and memory performance, not only in spatial cognition but also in self-awareness, and generalizes to downstream UAV decision-making tasks.Our results highlight the importance of self-awareness for advancing embodied spatial intelligence, and provide both a new benchmark and empirical evidence for motion-aware self-in-space modeling.

RealSkin: Spatio-Spectral Partial Neural Adjoint Maps for Image-to-3D Attribute Transfer
RealSkin:用于图像到3D属性转移的时空光谱部分神经伴随映射
Abstract
Creating photorealistic 3D assets requires bridging the appearance gap between real-world observations and synthetic models. A promising approach is to transfer visual attributes from real images onto synthetic 3D surfaces. Traditional methods struggle with resolution mismatch and the inherent discreteness of point correspondences. In contrast, resolution-robust functional maps enable smooth attribute propagation but rely on near-isometry assumptions and topological consistency. To address these limitations, we propose RealSkin, a self-supervised framework that performs correspondence optimization in a learned spectral domain, guided by spatial correspondences. We first introduce a spatial-guided registration algorithm to establish coarse correspondences under severe topological discrepancies. To relax strict isometric assumptions and handle partial correspondences, we further design a spectral-aware neural adjoint network that incorporates partial correspondences into a neural function space and models non-isometric residuals for correspondence refinement. Experimental results demonstrate that our method achieves state-of-the-art performance on challenging real-to-synthetic scenarios. The code will be publicly released.

TerraLogic:地球观测中分层地理空间推理的基准测试
Abstract
Beyond perception, reasoning is essential in remote sensing for advanced interpretation, inference, and decision-making. Recent advances in large language models (LLMs) have enabled tool-augmented agents that leverage external tools to perform complex analytical tasks. However, existing studies in remote sensing primarily focus on perception-oriented tasks, leaving cognitive geospatial reasoning largely underexplored. To address this gap, we introduce TerraLogic, a benchmark for geospatial reasoning. TerraLogic comprises 545 scenario-driven, hierarchy-aware tasks, such as hazard vulnerability assessment, urban heat island analysis, and forest fragmentation dynamics, spanning optical, Synthetic Aperture Radar (SAR), and infrared (IR) imagery. It advances evaluation beyond recognition and monitoring toward cognitive-level geospatial analysis. To facilitate evaluation on TerraLogic, we further propose HieraPlan, a tool-augmented agent that organizes toolkits into functional hierarchies and performs fault-tolerant reasoning. HieraPlan enables structured abstraction, robust recovery from tool failures, and stable long-horizon planning. Extensive experiments demonstrate that current approaches struggle with hierarchical geospatial reasoning, while HieraPlan provides a strong baseline with improved reasoning, cross-modal generalization, and error handling.

DynTrace: Tracking Dynamic Object Evidence for 4D Spatio-Temporal Reasoning in MLLMs
DynTrace:用于多模态大语言模型的4D时空推理的动态对象证据追踪
Abstract
4D spatio-temporal reasoning, jointly modeling 3D spatial structure and temporal evolution, is essential for understanding dynamic worlds and enabling embodied interaction. While current Multimodal Large Language Models (MLLMs) show strong capabilities in static scene understanding and coarse-grained 4D tasks, they still have notable limitations in continuous dynamic scene perception, especially in tracking dynamic object evidence for coherent 4D spatio-temporal reasoning. This shortcoming stems mainly from relying on sparse frame-level observations, fragmenting continuous dynamic cues and leaving models unable to disentangle genuine object dynamics from camera-induced apparent motion. Inspired by humans tracking dynamic cues while compensating for viewpoint changes, we propose DynTrace, a training-free framework for 4D spatio-temporal reasoning with two complementary components. Dynamic Trajectory Visualization (DTV) reprojects world-coordinate trajectories onto the image plane, providing geometry-informed visual priors that disentangle genuine object dynamics from camera-induced apparent motion. Meanwhile, the Dynamic Trace Token (DT-Token), organized into a Dynamic Trace Graph (DTG), tracks object-level dynamic cues, trace evolution, and key moments, maintaining continuous dynamic object evidence for coherent 4D reasoning. Together, these two components equip MLLMs with continuously tracked dynamic object evidence, grounded in geometry-informed visual priors and structured spatio-temporal traces.

4D时空推理联合建模3D空间结构和时间演变,对于理解动态世界和实现具身交互至关重要。尽管当前的多模态大语言模型(MLLMs)在静态场景理解和粗粒度4D任务中表现出强大的能力,但在连续动态场景感知方面仍存在显著局限,尤其是在追踪动态对象证据以实现连贯的4D时空推理方面。这一短板主要源于依赖稀疏的帧级观察,导致连续动态线索的碎片化,使得模型无法将真实的对象动态与相机引起的表观运动区分开。受到人类在补偿视角变化时追踪动态线索的启发,我们提出了DynTrace,一个无训练的4D时空推理框架,包含两个互补组件。动态轨迹可视化(DTV)将世界坐标轨迹重投影到图像平面,提供几何信息驱动的视觉先验,以区分真实的对象动态和相机引起的表观运动。同时,动态追踪标记(DT-Token)组织成动态追踪图(DTG),追踪对象级动态线索、轨迹演变和关键时刻,保持连续的动态对象证据以实现连贯的4D推理。这两个组件共同为MLLMs提供了基于几何信息驱动的视觉先验和结构化时空轨迹的连续追踪动态对象证据。DynTrace持续改善开源MLLMs,在Dyn-Bench、VLM4D和DSI-Bench上取得了最先进的结果,验证了追踪动态对象证据对于稳健的4D时空推理的重要性。

DiTailed: Ensuring Visual Object Consistency in Text-Image-to-Image Flow Matching Models
DiTailed:确保文本-图像-图像流匹配模型中的视觉对象一致性
Abstract
Despite remarkable progress in text-guided image editing, generative models frequently fail to preserve visual object consistency, defined as the preservation of a subject's key attributes throughout the editing process. We address this limitation through three contributions. First, we introduce ABO-Edit, a dataset specifically designed to study object consistency, comprising over 12,000 triplets of source images, editing prompts, and high-quality target images rendered from artist-designed 3D assets, with multi-view coverage and human-verified quality control. Second, we uncover an overlooked property of image-editing rectified flow models: the conditioning embedding space, not directly supervised during training, encodes a prediction of the final generated image even at high noise levels. Third, exploiting this finding, we propose FlowMirror, a parameter-free auxiliary loss that supervises this conditioning embedding space. Without architectural changes, our method improves generation quality across several metrics over baselines.

Edge-Aware Thermal Infrared UAV Swarm Tracking
边缘感知热红外无人机群体跟踪
Abstract
Thermal infrared (TIR) imaging is essential for UAV swarm operations in visually degraded environments. However, tracking tiny UAVs remains challenging due to limited appearance cues, frequent occlusions, and rapid maneuvers. Despite significant progress driven by benchmarks such as the Anti-UAV challenge, existing methods primarily prioritize accuracy while overlooking the computational constraints of real-time edge deployment. The standard Kalman Filter (KF) offers the efficiency required for edge devices, yet its constant-velocity assumption often breaks down under highly dynamic UAV motion and thermal sensor jitter. More sophisticated nonlinear estimators can improve robustness but often introduce additional computational costs. To address this gap, we propose an edge-aware online tracking pipeline centered on the Adaptive Kinematic Kalman Filter (AKKF), which augments the linear KF with state-dependent kinematic modeling while preserving real-time efficiency. Combined with transient false-positive suppression and kinematics-driven predictive coasting, the presented pipeline improves trajectory continuity under challenging TIR conditions. Experiments on the Beyond Strong Baseline (BSB) benchmark provide a starting point for edge-aware UAV tracking by jointly evaluating tracking performance and computational efficiency, offering insights toward future real-time deployment.

CGRL: Concept-Guided Pruning and Representation Learning for Whole-Slide Image Classification
CGRL:基于概念引导的修剪与表示学习用于全幻灯片图像分类
Abstract
Weakly supervised whole-slide image (WSI) classification is widely used in computational pathology because slide-level labels are easier to obtain than dense region annotations. Existing multiple instance learning (MIL) methods often aggregate large bags of patch embeddings using mainly visual cues, which can retain many non-informative patches and provide weak alignment between instance features and class-level disease semantics. We propose Concept-Guided Pruning and Representation Learning (CGRL), a simple framework that introduces class-level concept prototypes derived from disease prompts into the MIL pipeline. First, concept-relevance pruning ranks patch instances by their similarity to class concepts and retains the top-K concept-relevant patches for downstream MIL aggregation. Second, concept-guided contrastive representation learning constructs class-wise positive and negative patch sets from the same similarity matrix and optimizes target-class, symmetric auxiliary, and cross-class separation objectives, thereby regularizing the projected concept space. We evaluate CGRL on TCGA-BRCA and TCGA-NSCLC using multiple representative MIL methods. Experimental results show that CGRL improves several model-dataset combinations, with gains depending on the downstream MIL model and dataset. It achieves particularly clear improvements in accuracy and macro-F1 while reducing computational cost through concept-relevance pruning. These findings demonstrate that class-level semantic concepts provide an effective and practical prior for patch selection and representation learning in weakly supervised computational pathology.

Gaussian Mixture Modeling for Event-Aware Visual Allocation in Long Video Understanding
用于事件感知视觉分配的高斯混合建模在长视频理解中的应用
Abstract
Large Vision-Language Models (LVLMs) face significant challenges in long video understanding due to the excessive computational cost and information loss associated with uniform sampling. Existing keyframe selection methods often treat video frames as atomic entities and allocate visual budgets equally, thereby overlooking high-level semantic structures and introducing substantial redundancy. To address these limitations, we propose GMM-EVA (Gaussian Mixture Modeling for Event-Aware Visual Allocation), which leverages Gaussian Mixture Models to model event-level structure from discrete frame-wise observations. A differentiated allocation strategy is then applied to preserve one primary high-resolution keyframe per event for high-fidelity detail, while utilizing lower-resolution secondary keyframes to maintain temporal context and optimize token budgets. GMM-EVA is a training-free, plug-and-play framework that generalizes robustly across various relevance measures and downstream LVLMs. Extensive experiments on multiple long video benchmarks demonstrate that our method significantly outperforms uniform sampling. Notably, GMM-EVA achieves comparable performance to baseline selection methods while utilizing only approximately half of the visual token budget, highlighting its superior efficiency and effectiveness.

Traceback Translators Against Forgetting in Continual Fake Speech Detection
针对持续假语音检测中的遗忘问题的追溯翻译器
Abstract
Fake speech detectors are increasingly challenged by the development of new and more accurate generative models. To cope with this problem, continual learning techniques are nowadays widely considered feasible strategies for updating models to new datasets, but they also lead to decreased performance on previously seen samples (catastrophic forgetting). In this work, we propose a forgetting-resilient solution based on the adoption of domain translators within a frozen detector, which remaps the new feature spaces into the original ones by means of a traceback translator network. Experimental results show that this strategy enables the achievement of high detection rates with respect to traditional retraining, while minimizing the computational effort and preserving the detection accuracy on previous data.

WanToFight:用于多人战斗互动的实时生成游戏引擎
Abstract
We present WanToFight, a generative game engine that simulates real-time, two-player The King of Fighters '97 (KOF~'97) gameplay from keyboard input. Prior generative game engines target either single-player first-person settings or non-real-time cooperative scenarios; multi-player control, real-time inference, complex physical interaction, and adversarial gameplay have not been jointly addressed. WanToFight closes this gap with three components built on the Wan-1.3B video diffusion transformer: a streaming autoregressive generator with block-causal attention and a rolling KV cache; a visually grounded Player Association module that binds each player's keyboard signal to a character identity; and a gated, locally causal keyboard injection module trained with a single-player-to-full-gameplay curriculum. A four-step DMD-distilled student paired with a pruned VAE decoder sustains 30FPS at 512x384 on a single NVIDIA RTX 5090 over the duration of a complete match. To our knowledge, WanToFight is the first generative game engine to combine multi-player control, real-time inference, complex physical interaction, and adversarial gameplay in one system.

Decouple and Reason: Anatomically Guided Two-Stage Voxel-Level Grounding of Free-Text Findings in 3D Chest CT
解耦与推理:解剖学指导的三维胸部CT中自由文本发现的两阶段体素级定位
Abstract
Automatic voxel-level grounding of free-text findings in 3D chest Computed Tomography (CT) is critical for clinical interpretability. However, this task remains highly challenging due to the intricate spatial complexity of large 3D volumes and the heterogeneity of free-text findings. Existing end-to-end approaches often struggle to simultaneously learn the localized feature representations required for accurate 3D segmentation and the complex semantic understanding needed for text alignment, leading to suboptimal grounding performance. To overcome this fundamental limitation, we propose a novel decoupled framework that disentangles the problem into two specialized stages: (1) class-agnostic lesion segmentation and (2) text-volume reasoning. This structural separation allows the model to first extract candidate sub-volumes by localizing potential abnormalities. Subsequently, intensive cross-modal reasoning is performed to align these localized sub-volumes with free-text medical findings. To resolve the spatial ambiguities inherent in local regions, the reasoning module is augmented with explicit anatomical guidance, utilizing relative spatial coordinates and lung lobe priors. Evaluated on the ReXGroundingCT benchmark, our method achieves state-of-the-art performance in overall grounding quality on the official leaderboard. These results demonstrate that decoupling detection from reasoning is a highly effective paradigm for handling the complexity of 3D medical visual grounding.

Towards Vision-Free CIR: Attribute-Augmented Scoring and LLM-Based Reranking for Zero-Shot Composed Image Retrieval
面向无视觉的复合图像检索:基于属性增强评分和大型语言模型重排序的零-shot方法
Abstract
Recent work has shown that "Vision-Free'' approaches (representing images as text) can be effective for standard image retrieval tasks. However, it remains unclear whether this paradigm can effectively handle a more complex, multimodal task, Composed Image Retrieval (CIR), due to the inherent information loss in textual descriptions. In this paper, we introduce a Vision-Free CIR framework that addresses this challenge through two key techniques: (1) Attribute-Augmented Hybrid Scoring, which compensates for lost visual details via explicit attribute matching, and (2) LLM-Based Reranking, which verifies semantic consistency of top candidates. Experiments on the open-domain CIRR dataset show that our approach outperforms existing Zero-shot CIR methods (44.04% R@1, +8.79%). On FashionIQ, our results highlight the trade-off between semantic reasoning and fine-grained visual matching. Ablation studies reveal that both attribute-augmented scoring and LLM-Based Reranking consistently improve performance.

MAGE: Color-Invariant and Spatial Knowledge Distillation for Gastric Neoplasm Classification
MAGE:用于胃肿瘤分类的颜色不变性和空间知识蒸馏
Abstract
Accurate differentiation between gastric adenoma and carcinoma during endoscopy is critical for clinical decision-making. Yet, this task is highly challenging due to high inter-class similarity and ambiguous boundaries between the two classes. Existing ROI-based classification methods often suffer from detection/segmentation error propagation and loss of surrounding global context. In contrast, full-image classification lacks the necessary spatial focus. Furthermore, we observe that deep neural networks gravitate towards domain-specific texture biases(e.g. bleeding, lighting artifacts), often causing models to predict based on spurious correlations instead of intrinsic morphological features. To address these limitations, we propose a novel framework, Masked Achromatic Guidance Expert (MAGE). During training, we introduce an auxiliary local expert branch trained on masked achromatic views of the neoplasm. By suppressing background context and color, this branch is forced to learn highly discriminative, purely structural features. We then employ a dual-objective distillation strategy, transferring both classification logits and spatial attention maps to provide implicit spatial supervision to the main branch that receives full WLI as input. This dual-objective distillation forces the model to ground its predictions in morphology rather than relying on shortcuts, while still retaining clinically relevant color cues. At inference time, our deployable model operates on images without annotated masks, ensuring real-time deployability . Extensive experiments on a clinical gastric endoscopy dataset show that our method significantly outperforms existing detection-based methodologies (e.g. YOLO) and classification-based methodologies (e.g. Swin-Transformer), providing not only superior classification performance but also interpretable attention maps for clinical reliability.

在内窥镜检查中准确区分胃腺瘤和癌症对临床决策至关重要。然而,由于两类之间高度的类间相似性和模糊的边界,这一任务极具挑战性。现有的基于感兴趣区域(ROI)的分类方法常常受到检测/分割错误传播和周围全局上下文丧失的影响。相比之下,完整图像分类缺乏必要的空间聚焦。此外,我们观察到深度神经网络倾向于域特定的纹理偏差(例如出血、光照伪影),这常常导致模型基于虚假的相关性而非内在形态特征进行预测。为了解决这些局限性,我们提出了一种新颖的框架,称为Masked Achromatic Guidance Expert(MAGE)。在训练过程中,我们引入一个辅助的局部专家分支,该分支在肿瘤的掩蔽无色视图上进行训练。通过抑制背景上下文和颜色,该分支被迫学习高度区分的纯结构特征。随后,我们采用双目标蒸馏策略,将分类逻辑和空间注意力图转移到主分支,以提供隐式空间监督,该主分支接收完整的白光内窥镜图像作为输入。这种双目标蒸馏迫使模型将其预测基于形态学而非依赖捷径,同时仍保留临床相关的颜色线索。在推理时,我们可部署的模型在没有注释掩膜的图像上运行,确保实时可部署性。在临床胃内窥镜数据集上的广泛实验表明,我们的方法显著优于现有的基于检测的方法(例如YOLO)和基于分类的方法(例如Swin-Transformer),不仅提供了更优越的分类性能,还提供了可解释的注意力图,以确保临床可靠性。

Text-Aided Multi-Modal Panoptic Symbol Spotting for CAD Floor Plan Drawings
文本辅助的多模态全景符号识别用于计算机辅助设计平面图
Abstract
Computer-Aided Design (CAD) floor plan drawings contain both graphical primitives and textual annotations, which provide complementary geometric and semantic cues for intelligent design understanding. Among CAD analysis tasks, panoptic symbol spotting has become increasingly important with the growing demand for industrial digitalization and deep learning-based automation. However, most existing methods remain primarily primitive-centric and underexploit textual annotations, despite their critical semantic value. Even the few text-aware approaches often treat annotations only superficially, without properly modeling complex syntax and hierarchical semantics of CAD annotations, which leads to semantic loss and suboptimal spotting performance. To address these limitations, we propose TextCAD, a multimodal framework that jointly models graphical primitives and textual annotations for panoptic symbol spotting. Specifically, we design a Type-Attribute Correlation Encoder (TACE) to explicitly encode the compositional semantics within annotations by jointly modeling their types and attributes. We further introduce a Semantic Hierarchy Alignment framework with Multi-level Semantic Filtering (MSF) and primitive downsampling, which adaptively aligns annotation semantics with graphical primitives at different semantic levels and enables accurate cross-modal semantic injection and fusion. Experiments on real-world building-design datasets show that TextCAD effectively improves symbol spotting performance and achieves state-of-the-art results.

ReflectVLN: Training Vision-Language Navigation Agents with Reflective Reasoning
ReflectVLN:通过反思推理训练视觉-语言导航代理
Abstract
Existing vision-language navigation methods often couple a VLM with waypoint decoders to produce multi-step action plans, but they typically lack an explicit closed-loop mechanism for tracking semantic progress, diagnosing execution failures, and recovering from error accumulation in long-horizon navigation. To address this gap, we propose ReflectVLN, an agentic VLN framework that organizes decision-making through bidirectionally interactive intention and execution agents. The intention agent performs subtask decomposition and reflection, generating executable subtask descriptions as corrective plans. Conditioned on these descriptions, the execution agent grounds them into short-horizon actions under current observations while monitoring sub-goal progress and detecting off-track behavior. Crucially, ReflectVLN enables closed-loop bidirectional communication: the execution agent emits progress and deviation signals to trigger reflection and subtask updates on demand, and the intention agent returns structured guidance that reconditions subsequent actions for recovery. To encourage temporally coherent decisions with interpretable intermediate rationales, we introduce Action Chain-of-Thought (Action-CoT), a path-conditioned dual-query training scheme for action generation. Experiments on standard VLN benchmarks show that ReflectVLN improves success rates and path efficiency under a constrained data budget, with favorable training cost and fewer high-level intention calls at inference time, while providing interpretable intermediate decisions for analysis and collaboration.

We investigate the integration of Mamba into YOLO26, the latest non-maximum suppression (NMS)-free object detection framework, by proposing MambaPSA, a lightweight Mamba-based replacement for the C2PSA block at the end of the backbone. To complement this study, we additionally insert a bidirectional Vision Mamba (BiViM) module at the P3, P4, and P5 levels of the neck. Experiments on PASCAL VOC 2007+2012 show that MambaPSA reduces parameters by 2.9%, FLOPs by 12.1%, and improves CPU inference throughput by 17.6% (from 17 to 20 FPS) with negligible accuracy change (-0.1 mAP50:95), while the P4 BiViM placement yields the best accuracy gain (+0.9 mAP50:95). These results suggest that SSMs offer a favorable efficiency-accuracy trade-off when replacing attention-based blocks in NMS-free lightweight detectors.

Abstract
The segmentation of lesions in Moderate to Severe Traumatic Brain Injury (msTBI) from T1-weighted MRI presents a significant clinical challenge due to the profound heterogeneity of lesion characteristics in terms of size, shape, and location. To address this, the AIMS-TBI 2025 Challenge was organized to promote the development of robust and accurate segmentation algorithms. In this paper, we present our deep learning-based solution. Our methodology employs the nnU-Net framework with an adaptive intensity normalization strategy confined to the brain parenchyma, effectively reducing inter-subject variability and mitigating artifacts from non-brain structures. Upon final evaluation on the held-out test set, our method demonstrated highly competitive performance on the official leaderboard, achieving an Overall Dice Coefficient of 0.6305. The model obtained a Dice score of 0.4805 for lesion segmentation and 0.9324 for non-lesion tissue. While the lesion Dice reflects the difficulty of detecting highly heterogeneous lesions, the high non-lesion Dice primarily indicates the model's strong ability to correctly identify non-lesion voxels, demonstrating good specificity in differentiating lesion from non-lesion regions. These results demonstrate that incorporating anatomically constrained normalization within the nnU-Net pipeline is a powerful and effective strategy for tackling the complexities of msTBI lesion segmentation.

Feature-statistics augmentation such as MixStyle, EFDMix, and correlated style uncertainty improves generalization at low cost but perturbs channel statistics globally, treating each image as a single style; one class can then contaminate the augmentation of another. Domain generalization is understudied for multi-label remote sensing; no prior method or multi-source benchmark targets it. A label-decoupled augmentation framework is therefore proposed, confining style perturbation to label-specific regions. Per-label attention, obtained from a learnable module or from gradient class-activation maps, yields per-label feature statistics; these statistics are mixed with cross-domain samples that share present labels, under independent per-label coefficients, and features are recomposed by attention-weighted normalization. Three operators combined with two attention sources produce six variants, evaluated on a leave-one-domain-out benchmark from multi-label UCM, AID, and DFC15 over six shared labels. Averaged over three splits and five seeds, the best variant attains 71.5% mean average precision, exceeding empirical risk minimization by 5.0 points and the strongest global-statistics baseline by 1.3 points, with the largest gain on the hardest transfer (up to 7.7 points). Ablations indicate that spatial attention and refreshed localization maps are most influential. The framework adds at most 0.35% parameters, leaves inference unchanged, and appears to offer a generic, inexpensive upgrade path for multi-label statistics-based domain generalization.

多标签分类为每个航空场景分配多个共现标签,但实际部署的模型往往面临与训练数据分布不同的情况。特征统计增强方法,如 MixStyle、EFDMix 和相关风格不确定性,以低成本提高了泛化能力,但会全局扰动通道统计,将每幅图像视为单一风格;因此,一个类别可能会污染另一个类别的增强。针对多标签遥感的领域泛化研究相对较少,现有方法或多源基准尚未针对这一问题。因此,提出了一种标签解耦的增强框架,将风格扰动限制在特定标签的区域内。通过可学习模块或梯度类激活图获得的每标签注意力,生成每标签的特征统计;这些统计与共享当前标签的跨域样本混合,采用独立的每标签系数,并通过注意力加权归一化重新组合特征。结合三种操作符和两种注意力来源,产生六种变体,并在来自多标签 UCM、AID 和 DFC15 的留一域外基准上进行评估,涉及六个共享标签。经过三次划分和五次随机种子的平均,最佳变体达到了 71.5% 的平均精度,比经验风险最小化高出 5.0 个百分点,比最强的全局统计基线高出 1.3 个百分点,在最困难的迁移上获得了最大的增益(高达 7.7 个百分点)。消融实验表明,空间注意力和更新的定位图对结果影响最大。该框架最多增加 0.35% 的参数,推理不变,并且似乎为基于多标签统计的领域泛化提供了一条通用且低成本的升级路径。代码将在接受后提供,链接为 https://github.com/Alaa-Almouradi/Style-Augmentation-Upgrade。

Color Pass-Through via Camera-Display Coupling
通过相机-显示器耦合实现颜色透视
Abstract
When a real-world scene is captured by a smartphone camera and viewed on its screen, the displayed image often differs noticeably from the original scene in color, brightness, and contrast. This gap persists despite substantial advances in both modern cameras and displays. A key reason is that most pipelines factor the high-dimensional capture-to-display process into two separately calibrated camera and display stages, and then connect them through low-dimensional color transforms, leading to information bottlenecks and inevitable error accumulation. To address this systemic challenge, we propose Color Pass-Through, an end-to-end learned framework that operates directly on captured images. Our key insight is to treat the camera and display as a coupled system rather than calibrating them in isolation. Coupling the camera and display yields two practical advantages: (1) it brings the entire real-world scenes to the display via end-to-end optimization, and (2) it allows efficient one-step calibration for each distinct observer via complete capture-to-display path. We validate Color Pass-Through using both digital and human observers. Compared with representative baselines, our method achieves an average gain of +2.0 points on a 5-point user study and more than 2x improvement on quantitative metrics, demonstrating improved reproduction of the perceived color of the original scene.

当智能手机相机捕捉到现实世界场景并在其屏幕上显示时,显示的图像在颜色、亮度和对比度上往往与原始场景明显不同。这种差距在现代相机和显示器取得显著进展的情况下仍然存在。一个主要原因是大多数处理流程将高维的捕捉到显示过程分解为两个单独校准的相机和显示阶段,然后通过低维颜色变换将它们连接起来,这导致信息瓶颈和不可避免的误差累积。为了解决这一系统性挑战,我们提出了颜色透视(Color Pass-Through),这是一个端到端学习框架,直接对捕获的图像进行处理。我们的关键见解是将相机和显示器视为一个耦合系统,而不是单独校准它们。相机和显示器的耦合带来了两个实际优势:(1)通过端到端优化将整个现实世界场景传递到显示器上;(2)通过完整的捕捉到显示路径为每个不同的观察者提供高效的一步校准。我们使用数字和人类观察者验证了颜色透视。与代表性基线相比,我们的方法在5分制用户研究中平均获得+2.0分的提升,并在定量指标上实现了超过2倍的改善,证明了对原始场景感知颜色的再现能力得到了提升。

Weakly Supervised Spatio-Temporal Candidate Discovery of Dairy Farm Sites from Seasonal Satellite Imagery
基于季节性卫星影像的奶牛场地弱监督时空候选发现
Abstract
Farm site discovery from satellite imagery is a spatiotemporal candidate ranking problem because farm evidence is distributed across pasture, field boundaries, roads, buildings, and seasonal vegetation patterns. Direct farm labels are often incomplete, which makes fully supervised detection difficult. This paper proposes a weakly supervised pipeline for ranking dairy farm candidate clusters from seasonal Sentinel imagery and open map priors. The method uses aligned spring, summer, and autumn image tiles from County Cork, Ireland, with spectral bands, vegetation indices, built area indices, and a pasture channel. A Barlow Twins encoder learns multi-season tile embeddings without farm labels. In parallel, weak OpenStreetMap farm priors are split into a prior and a held-out set. Prior features support a rule-based tile score that combines farm proximity, seasonal pasture evidence, and summer greenness, while held-out features are reserved only for proxy evaluation. The rule score is smoothed over a spatial representation graph using geographic proximity and embedding similarity, and high-scoring tiles are grouped into ranked candidate clusters. From 26,722 valid tiles, the main run selects 535 high-confidence tiles and forms 71 candidate clusters. The top 5 clusters achieve 0.60 precision within 500 m and 0.80 precision within 1000 m of held-out OpenStreetMap farm features. The top 10 clusters achieve 0.40 precision within 500 m and 0.80 precision within 1000 m. The results show that seasonal representation learning and weak geographic priors can reduce large satellite image collections into compact candidate sets for human review.

从卫星影像中发现农场位置是一个时空候选排名问题,因为农场证据分布在牧场、田地边界、道路、建筑物和季节性植被模式中。直接的农场标签通常不完整,这使得完全监督的检测变得困难。本文提出了一种弱监督管道,用于从季节性Sentinel影像和开放地图先验中对奶牛场候选集群进行排名。该方法使用来自爱尔兰科克县的对齐春季、夏季和秋季影像切片,结合光谱波段、植被指数、建筑面积指数和牧场通道。Barlow Twins编码器在没有农场标签的情况下学习多季节影像切片的嵌入。同时,弱的OpenStreetMap农场先验被分为先验集和保留集。先验特征支持一个基于规则的影像切片评分,该评分结合了农场接近度、季节性牧场证据和夏季绿度,而保留特征仅用于代理评估。该规则评分通过地理接近度和嵌入相似性在空间表示图上进行平滑处理,高评分的影像切片被分组为排名候选集群。从26,722个有效影像切片中,主要运行选择了535个高置信度影像切片,并形成71个候选集群。前5个集群在距离保留的OpenStreetMap农场特征500米内实现了0.60的精度,在1000米内实现了0.80的精度。前10个集群在距离500米内实现了0.40的精度,在1000米内实现了0.80的精度。结果表明,季节性表示学习和弱地理先验能够将大量卫星影像集合缩减为紧凑的候选集供人工审查。

CRC-HGD: A Histopathological Image Dataset for Grading Colorectal Cancer
CRC-HGD:一种用于结直肠癌分级的组织病理图像数据集
Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer-related deaths globally, with approximately 1,926,425 new cases and 904,019 deaths reported in 2022. Accurate histologic grading plays a critical role in prognosis and treatment planning for colorectal adenocarcinoma. In recent years, artificial intelligence and its subcategories, including machine learning and deep learning, have been increasingly employed for automated cancer detection and classification. An appropriate and well-organized dataset is the essential first step to achieve this goal. This paper introduces CRC-HGD, a histopathological microscopy image dataset of 1,914 images obtained from 214 colorectal adenocarcinoma patients (Grade I: 106, Grade II: 75, Grade III: 33). The specimens are H&E-stained colorectal tissue sections acquired at the Poursina Hakim Research Center of Isfahan University of Medical Sciences, Iran, diagnosed between 2014 and 2019, and graded according to the World Health Organization (WHO) criteria into three grades: well-differentiated (Grade I), moderately differentiated (Grade II), and poorly differentiated (Grade III). For each specimen, four magnification levels are provided: 4x, 10x, 20x, and 40x. The dataset is accessible via Mendeley Data (https://doi.org/10.17632/yfp5sfj47m.4) and at http://databiox.com, where the latest version is also available. The distinctive feature of this dataset is the provision of labeled specimens across all three differentiation grades at multiple magnification levels, enabling comprehensive computational analysis of colorectal cancer grading.

Hallo4D: Multi-Modal Hallucination Mitigation for Consistent Spatio-Temporal Generation
Hallo4D:用于一致性时空生成的多模态幻觉缓解
Abstract
While recent advances in 3D generation have enabled impressive visual synthesis, existing methods often rely on 2D diffusion supervision without explicit mechanisms for geometric consistency, leading to spatial hallucinations such as duplicated structures and misaligned geometry. These issues become more severe in 4D generation, where maintaining consistency across viewpoints and temporal evolution introduces additional challenges, including jitter, identity flicker, and structural drift. We present \textbf{Hallo4D}, a unified and model-agnostic framework for mitigating spatiotemporal hallucinations in 3D and 4D content generation. Hallo4D introduces a generation-detection-correction paradigm that leverages large multimodal language models (LMMs) to identify and summarize spatial and temporal inconsistencies from multi-view and multi-frame renderings. These insights guide a consensus-driven image-space consistency optimization, where an LMM-based selector evaluates candidate corrections through multi-model voting, without requiring retraining or architectural modifications. To further improve temporal consistency and optimization efficiency, Hallo4D incorporates motion-aware keyframe sampling, LMM-guided initialization, and appearance alignment. We additionally introduce exposure-aware optimization and visibility pruning to enhance robustness under challenging viewpoints. Extensive experiments demonstrate that Hallo4D consistently outperforms strong baselines across diverse 3D and 4D generation settings, providing a scalable and generalizable solution for consistency-aware content generation.

尽管近年来3D生成技术取得了显著的视觉合成进展,但现有方法往往依赖于2D扩散监督,缺乏明确的几何一致性机制,导致空间幻觉,如重复结构和几何错位。这些问题在4D生成中变得更加严重,因为在视角和时间演变之间保持一致性带来了额外的挑战,包括抖动、身份闪烁和结构漂移。我们提出了 extbf{Hallo4D},一个统一且与模型无关的框架,用于缓解3D和4D内容生成中的时空幻觉。Hallo4D引入了一种生成-检测-修正范式,利用大型多模态语言模型(LMMs)识别和总结来自多视角和多帧渲染的空间和时间不一致性。这些见解指导了一种基于共识的图像空间一致性优化,其中基于LMM的选择器通过多模型投票评估候选修正,而无需重新训练或架构修改。为了进一步提高时间一致性和优化效率,Hallo4D结合了运动感知关键帧采样、LMM引导初始化和外观对齐。我们还引入了曝光感知优化和可见性修剪,以增强在挑战性视角下的鲁棒性。大量实验表明,Hallo4D在多种3D和4D生成设置中始终优于强基线,提供了一种可扩展且具有普适性的解决方案,以实现一致性意识的内容生成。

RFMSR: Residual Flow Matching for Image Super-Resolution
RFMSR:用于图像超分辨率的残差流匹配
Abstract
Image super-resolution (ISR) has witnessed remarkable progress with diffusion models and flow matching. The dominant text-to-image (T2I) based approaches leverage large-scale foundation models as generative priors, achieving impressive perceptual quality but at the cost of massive model sizes and prohibitive training expenses. Recent flow-matching-based vision-only approaches have made significant strides; however, they adopt standard flow formulations that transport from a pure Gaussian prior to the data distribution, discarding the rich structural information already present in the low-quality (LQ) input. Furthermore, existing single-step acceleration techniques often forfeit the model's multi-step inference capability. In this paper, we propose Residual Flow Matching for Image Super-Resolution (RFMSR), a vision-only framework that centers the source distribution at the LQ latent, reducing transport distance and preserving structural priors throughout the flow trajectory. We further introduce a two-phase training strategy: Phase I pretrains the velocity field via conditional flow matching, while Phase II applies end-to-end supervision to the single-step prediction while retaining the velocity loss across all timesteps, achieving high-quality single-step generation without sacrificing multi-step refinement. Extensive experiments demonstrate that RFMSR achieves comparable or even superior perceptual quality compared to state-of-the-art (SOTA) methods.

VisCo: Leveraging Large Language Models as Intrinsic Encoders for Visual Token Compression
VisCo:利用大型语言模型作为视觉标记压缩的内在编码器
Abstract
Vision-language models (VLMs) process large numbers of visual tokens, resulting in substantial inference latency and memory overhead. This has motivated extensive research on visual token compression. While training-free strategies rely on heuristic metrics and suffer significant performance degradation under high compression ratios, many training-based methods introduce external compression modules that force the VLM backbone to adapt, incurring substantial retraining cost and compromising VLMs' priors. Effective visual token compression hinges on strong information encoding, a capability already present in pretrained VLMs but underutilized by existing approaches. Motivated by this, we propose VisCo, a training-efficient self-compression framework that reuses the pretrained VLM itself as an intrinsic compressor. VisCo is a parameter-sharing autoencoder that compresses visual information using a small set of memory tokens and transfers hierarchical information from encoding to decoding. Experiments show that VisCo surpasses prior methods across all evaluated compression ratios, with larger gains under more aggressive compression, and remains stable even in the extreme single-token setting. Moreover, when combined with the original visual tokens, the learned memory tokens can even improve the base model, suggesting that VisCo captures complementary representations beyond compression.

EvoGraph-R1: Self-Evolving Multimodal Knowledge Hypergraphs for Agentic Retrieval
EvoGraph-R1:自我演化的多模态知识超图用于智能检索
Abstract
Retrieval-augmented generation (RAG) has emerged as a critical paradigm for grounding Multimodal Large Language Models (MLLMs) in external knowledge. Recent GraphRAG methods introduce structured entity-relation graphs to improve retrieval and reasoning. However, they remain limited by treating knowledge graphs as static data structures built offline and queried in a single pass. This static paradigm misaligns with the interactive, iterative nature of knowledge-intensive reasoning, creating three bottlenecks: (i) text-centric fragmentation that impedes cross-modal reasoning, (ii) frozen structures unable to incorporate new evidence or correct errors, and (iii) rigid single-pass retrieval without adaptive refinement. To overcome these limitations, we introduce EvoGraph-R1, a self-evolving GraphRAG framework that reconceptualizes knowledge graphs as dynamic environments shaped through agent interactions. We formulate retrieval as a Markov Decision Process (MDP) where the agent observes the graph state and executes actions to query (GraphRetrieve), expand (WebSearch), refine (GraphEdit), or terminate (Answer) the reasoning. These actions reshape the hypergraph structure and generate feedback signals that guide subsequent evolution. Through this closed loop, the hypergraph evolves by integrating new evidence, correcting errors, and refining structure to support multi-hop reasoning. Experiments on multimodal VQA and text QA benchmarks demonstrate substantial improvements over existing RAG baselines in accuracy, coverage, and traceability, establishing self-evolving knowledge graphs as a fundamental paradigm across modalities.

Abstract
This article presents our results for the 11th Affective Behavior Analysis in-the-Wild (ABAW) competition. For multi-task learning with simultaneous prediction of valence, arousal, facial expressions, and action units on s-Aff-Wild2 dataset, we use frozen lightweight facial extractors, MT-EmotiDDAMFN and MT-EmotiEffNet-B0, with separate heads and systematic post-processing: temporal Gaussian smoothing, per-class expression bias, AffectNet blending, per-AU threshold tuning, and weighted backbone fusion. On the official validation set, our ensemble significantly exceeds the performance of the ConvNeXt baseline. For ambivalence/hesitancy video recognition on the expanded BAH dataset, we extend the audiovisual pipeline to video-level Macro F1 by late fusion of face, HuBERT audio, and RoBERTa text classifiers, temporal aggregation, and a global-text gate. Frame-level Weighted F1 on validation set rises from 0.74 in ABAW-8 to 0.79, while the best public-test video-level Macro F1 reaches 0.73. In both tasks, competitive performance is achieved without fine-tuning heavy backbones. These results indicate that systematic prediction calibration and lightweight multimodal fusion can rival substantially heavier end-to-end approaches while offering improved efficiency and deployment flexibility.

MBTI: A Multi-Branch Efficient Fine-Tuning Framework for Hyperspectral Image Classification with Foundation Models
MBTI:一种基于基础模型的多分支高效微调框架,用于高光谱图像分类
Abstract
Hyperspectral foundation models learn transferable spectral-spatial representations from large-scale unlabeled data. They provide an effective paradigm for adapting to downstream hyperspectral image (HSI) classification tasks with limited labeled samples. However, spectral band configurations vary substantially across sensors, which makes direct model transfer difficult. Existing adaptation strategies often compress, select, or reshape the original spectra to match model-specific input requirements. These operations may discard useful spectral information and weaken local spectral continuity. To address this problem, we propose MBTI, a Multi-Branch efficient fine-tuning framework for Hyperspectral Image classification. MBTI adapts hyperspectral foundation models to downstream classification tasks while preserving full-band spectral information. First, we introduce a spectral-continuity-preserving multi-branch preprocessing strategy. The original HSI is divided into multiple continuous spectral subsets, and a band reuse mechanism is used when the remaining bands cannot form a complete branch. This avoids invalid padding and unnecessary spectral loss. Second, independent Low-Rank Adaptation (LoRA) modules are inserted into each branch. They enable different spectral intervals to learn task-specific discriminative features while keeping most pre-trained parameters frozen. Finally, a multi-branch channel attention fusion module adaptively recalibrates and integrates features from all spectral branches. Experiments on three public hyperspectral datasets show that MBTI achieves competitive and superior performance compared with representative classification methods. Under the final rank-8 configuration, only about 2.33\%--2.36\% of the parameters are trainable. The code will be available at https://github.com/Azhenmiddleblock/MBTI/tree/main.

高光谱基础模型从大规模未标记数据中学习可转移的光谱-空间表示。它们为适应下游高光谱图像(HSI)分类任务提供了一种有效的范式,尤其是在标记样本有限的情况下。然而,不同传感器的光谱带配置差异显著,这使得直接模型迁移变得困难。现有的适应策略通常通过压缩、选择或重塑原始光谱来满足模型特定的输入要求。这些操作可能会丢弃有用的光谱信息,并削弱局部光谱连续性。为了解决这个问题,我们提出了MBTI,一种用于高光谱图像分类的多分支高效微调框架。MBTI在适应下游分类任务的同时,保留了全带光谱信息。首先,我们引入了一种光谱连续性保持的多分支预处理策略。原始HSI被划分为多个连续的光谱子集,当剩余的光谱带无法形成完整的分支时,采用带重用机制。这避免了无效的填充和不必要的光谱损失。其次,独立的低秩适应(Low-Rank Adaptation, LoRA)模块被插入到每个分支中。它们使不同的光谱区间能够学习任务特定的判别特征,同时保持大部分预训练参数不变。最后,一个多分支通道注意力融合模块自适应地重新校准和整合来自所有光谱分支的特征。在三个公共高光谱数据集上的实验表明,MBTI与代表性的分类方法相比,取得了具有竞争力和优越的性能。在最终的8级配置下,只有约2.33%--2.36%的参数是可训练的。代码将发布在 https://github.com/Azhenmiddleblock/MBTI/tree/main。

ExtraGS: Enhancing Endoscopic View Extrapolation via Diffusion-Guided 3D Gaussian Splatting
ExtraGS:通过扩散引导的三维高斯散射增强内窥镜视图外推
Abstract
Robot-assisted minimally invasive surgery (MIS) critically depends on reliable endoscopic perception for navigation and safety. However, conventional endoscopes provide only a limited field of view, leaving large portions of surrounding anatomy unobserved. Recent neural rendering approaches, such as Neural Radiance Fields and 3D Gaussian Splatting, enable novel view synthesis from endoscopic videos, but their reliance on sparse observations often leads to severe artifacts when extrapolating beyond the training trajectory.In this work, we propose ExtraGS, a framework for enhancing endoscopic view extrapolation via diffusion-guided 3D Gaussian Splatting. Starting from an initial reconstruction, we introduce an uncertainty-guided virtual camera sampling strategy to actively explore blind spots and maximize information gain. The rendered views from these sampled locations are refined using a diffusion model to recover plausible anatomical structures, producing pseudo observations that guide further optimization. To prevent the generated content from degrading reliable regions, we adopt a confidence-weighted fine-tuning strategy when incorporating these pseudo observations.Extensive experiments on multiple public endoscopic datasets demonstrate that ExtraGS significantly reduces extrapolation artifacts and achieves state-of-the-art performance in endoscopic novel view synthesis.

We introduce UniVR, the first investigation into simultaneously learning complex reasoning, fine-grained physical dynamics, and long-term planning from pure visual demonstrations. At its core, UniVR features VR-GRPO, a reinforcement learning paradigm with complementary global and step-level rewards. This approach enforces logical coherence and physical consistency throughout the reasoning process without requiring task-specific heuristics or image-text pairs. To train and evaluate UniVR, we construct VR-X, a large-scale benchmark curated from 16 diverse sources spanning long-horizon manipulation, spatial puzzles, and physical reasoning. It is the first comprehensive suite to assess these heterogeneous capabilities under a purely visual protocol. Remarkably, UniVR achieves up to a 25% improvement on VR-X, and its superior visual reasoning also boosts performance on various multimodal understanding benchmarks. These findings underscore the vast potential of reasoning within visual spaces, with all code, data, and models are open-sourced for further research.

Breaking D\'ej\`a Vu: Independent Auditing of Visual Place Recognition through Vision-Language Reasoning
打破既视感:通过视觉-语言推理进行视觉位置识别的独立审计
Abstract
Visual place recognition (VPR) is a key enabler of accurate localization and long-term autonomous navigation in robotics applications, such as loop closure detection for simultaneous localisation and mapping (SLAM). However, real-world VPR deployment relies on selecting an image matching threshold that balances precision and recall. These thresholds are typically tuned using labeled validation data and fixed during deployment, making them unreliable under environmental changes where ground truth is unavailable. This is particularly problematic in safety-critical robotics, where accepting a false loop closure can corrupt the estimated trajectory and map. In this work, we introduce Visual Place Recognition Auditing, an independent post-retrieval verification framework that leverages Vision-Language Models (VLMs) to assess retrieved matches by reasoning jointly over query and candidate images. Unlike conventional verification methods, our approach performs instance-level verification without requiring architecture-specific confidence measures, dataset-dependent thresholds, or prior knowledge of the deployment environment. We evaluate our method on six benchmark datasets using five state-of-the-art VPR methods and four VLMs. Results show that VLM-based auditing improves recall@1 by 13.6% on average as compared to state-of-the-art methods while reducing false acceptance rates to 12%, maintaining precision above 95% and coverage above 75%.

视觉位置识别(VPR)是实现精确定位和长期自主导航的关键,广泛应用于机器人领域,例如用于同时定位与地图构建(SLAM)的回环闭合检测。然而,现实世界中的 VPR 部署依赖于选择一个图像匹配阈值,以平衡精确率和召回率。这些阈值通常使用标记的验证数据进行调整,并在部署期间保持不变,这使得它们在环境变化且缺乏真实情况时变得不可靠。这在安全关键的机器人应用中尤其成问题,因为接受错误的回环闭合可能会破坏估计的轨迹和地图。在本研究中,我们引入了视觉位置识别审计(Visual Place Recognition Auditing),这是一个独立的后检索验证框架,利用视觉-语言模型(Vision-Language Models, VLMs)通过对查询图像和候选图像的联合推理来评估检索到的匹配。与传统的验证方法不同,我们的方法在实例级别进行验证,无需特定于架构的置信度度量、依赖于数据集的阈值或对部署环境的先验知识。我们在六个基准数据集上评估了我们的方法,使用了五种最先进的 VPR 方法和四种 VLM。结果表明,与最先进的方法相比,基于 VLM 的审计在召回率@1 上平均提高了 13.6%,同时将错误接受率降低到 12%,保持精确率超过 95% 和覆盖率超过 75%。

AVSCap: Orchestrating Audio-Visual Synergy for Omni-modal Video Captioning
AVSCap:协调音频-视觉协同以实现全模态视频字幕生成
Abstract
Omni-modal video captioning is not merely combining visual captioning with audio transcription: a useful caption must describe how visual actions, speech, music, and sound effects co-evolve. Existing large multimodal models often fail at this relational step, treating audio and visual streams as loosely coupled observations, relying on automatic speech recognition, and under-specifying non-speech sounds and their links to visual events. We present AVSCap, a framework for audio-visual captioning centered on explicit cross-modal event binding. First, we construct AVSCap-130K, a tri-modal training corpus generated by a decoupled-then-fused pipeline that anchors visual and acoustic evidence before composing grounded omni-modal captions. Second, we train AVSCap-7B, a 7B captioner with a two-stage strategy: supervised fine-tuning establishes baseline capabilities, while sample-efficient reinforcement learning uses hybrid rewards to optimize acoustic completeness and audio-visual synergy. Our scaling analysis shows that reinforcement learning brings larger gains than increasing SFT data. Third, we introduce AVSCapBench, a benchmark that decomposes captions into visual, audio, and synergy events and evaluates them with fine-grained event recall. Experiments on AVSCapBench and external benchmarks show that AVSCap-7B improves non-speech audio coverage and cross-modal binding, delivering the best overall performance among evaluated open-source models.

全模态视频字幕生成不仅仅是将视觉字幕与音频转录相结合:有效的字幕必须描述视觉动作、语言、音乐和音效如何共同演变。现有的大型多模态模型往往在这一关系步骤上表现不佳,将音频和视觉流视为松散耦合的观察,依赖于自动语音识别,并未充分指定非语音声音及其与视觉事件的联系。我们提出了AVSCap,一个以显式跨模态事件绑定为中心的音频-视觉字幕生成框架。首先,我们构建了AVSCap-130K,这是一个通过解耦-再融合管道生成的三模态训练语料库,在构建有根基的全模态字幕之前,锚定视觉和声学证据。其次,我们训练了AVSCap-7B,这是一个具有两阶段策略的7B字幕生成器:监督微调建立基线能力,而样本高效的强化学习则利用混合奖励来优化声学完整性和音频-视觉协同。我们的规模分析表明,强化学习带来的收益大于增加监督微调数据。第三,我们引入了AVSCapBench,一个将字幕分解为视觉、音频和协同事件的基准,并通过细粒度事件召回进行评估。在AVSCapBench和外部基准上的实验表明,AVSCap-7B改善了非语音音频的覆盖率和跨模态绑定,在评估的开源模型中提供了最佳的整体性能。

LARAD: Layout-Aware Road Anomaly Detection via Spatial-Logic Reasoning
LARAD:基于空间逻辑推理的布局感知道路异常检测
Abstract
Accurate open-world obstacle detection is critical for autonomous driving. Current anomaly segmentation methods suffer from a fundamental blind spot: they over-rely on texture novelty to identify out-of-distribution (OoD) objects while ignoring contextual spatial logic. Furthermore, mitigating the resulting false positives often requires cascading massive vision models, introducing unacceptable inference latency. To address these issues, we propose Layout-Aware Road Anomaly Detection (LARAD), shifting the paradigm from appearance matching to spatial-logic reasoning. First, we introduce the Spatial-Logic Violation Synthesis (SLVS) pipeline, which generates training samples that are texture-consistent yet spatially invalid, forcing the model to learn contextual violations. Second, we augment a standard closed-set segmentation network with a lightweight, OoD-guided attention branch. Extensive experiments demonstrate that LARAD significantly enhances robustness against logical anomalies and establishes a new state-of-the-art, all while retaining the high efficiency of a single-model architecture.

准确的开放世界障碍物检测对自动驾驶至关重要。目前的异常分割方法存在一个根本性的盲点:它们过于依赖纹理新颖性来识别分布外(OoD)对象,而忽视了上下文空间逻辑。此外,缓解由此产生的误报通常需要级联大量视觉模型,这会引入不可接受的推理延迟。为了解决这些问题,我们提出了布局感知道路异常检测(LARAD),将范式从外观匹配转变为空间逻辑推理。首先,我们引入了空间逻辑违反合成(SLVS)管道,该管道生成纹理一致但空间无效的训练样本,迫使模型学习上下文违反。其次,我们在标准的闭集分割网络中增强了一个轻量级的、基于OoD引导的注意力分支。大量实验表明,LARAD显著增强了对逻辑异常的鲁棒性,并建立了新的最先进水平,同时保持了单模型架构的高效性。

Statistical Non-linear Reconstruction Loss for Image Anomaly Detection
用于图像异常检测的统计非线性重建损失
Abstract
Reconstruction-based methods are a cornerstone of unsupervised image anomaly detection, but they remain vulnerable to \emph{outlier leakage}, where standard mean squared error (MSE) loss drives the model to faithfully reconstruct anomalous patterns. We propose a Non-linear Reconstruction Loss that applies a sigmoid-based squashing function to suppress high-magnitude features, preventing outliers from dominating optimization while preserving sensitivity to normal patterns. In addition, we introduce a statistical calibration scheme that selects the scaling factor $k$ from the confidence interval (CI) of the normal feature distribution, enabling data-driven control of the suppression strength. Our approach achieves competitive or superior anomaly detection performance compared to state-of-the-art methods, reaching 99.0\% Image-AUROC and 97.3\% Pixel-AUROC on MVTec-AD, and 95.3\% Image-AUROC and 99.0\% Pixel-AUROC on VisA. These results indicate that non-linear gradient suppression is an effective mechanism for mitigating outlier leakage and improving anomaly localization in unified industrial inspection settings. The implementation is available at https://github.com/mintii13/Statistical-Non-linear-Reconstruction-Loss.git.

Metric-Guided Synthetic Image Data Rendering for Deep Learning compatible with Agentic AI
适用于代理人工智能的深度学习的度量引导合成图像数据渲染
Abstract
Deep learning computer vision for scientific applications requires collecting and annotating large datasets in a laborious, expensive and error-prone process. Synthetic data generation through 3D modelling and rendering may simplify this process and increase the accuracy of annotations by generating them programmatically. However, minimising the domain gap between real and synthetic images visually is subjective and lacks systematic quantitative guidance. We present GraNatPy, a Python package with metrics to guide improvement of the rendered scene. We show that quantifiable increase in realism, diversity and size of rendered dataset correlates with improved visual perception of the scene and higher zero-shot performance of an object detection model. Furthermore, we demonstrated using photographs of virological plaque assays that gradient similarity affects performance on small object detection, which can be improved by mixing real and synthetic data. Finally, we turn procedural data rendering into an agentic skill (SynthClaw) to automate the procedural parameter optimisation.

Inhibited Self-Attention: Sharpening Focus in Vision Transformers
抑制自注意力:在视觉变换器中聚焦
Abstract
Vision Transformers (ViTs) have demonstrated remarkable performance in computer vision tasks. However, their self-attention mechanism often diffuses focus across background regions, relying on spurious correlations rather than object-relevant cues. Inspired by inhibitory mechanisms observed in biological vision systems, we propose the Inhibited Self-Attention (ISA), a novel self-attention that integrates inhibitory signals to enhance feature selectivity and suppress spurious responses. In contrast to conventional self-attention, which relies solely on positive attention values due to softmax normalization, our approach retains and utilizes negative attention scores to suppress irrelevant features and sharpen focus on objects of interest. Experiments across multiple datasets, including ImageNet-1k and COCO, and several robustness benchmarks demonstrate that ISA enhances object-centric selectivity, reduces shortcut reliance, and improves out-of-distribution generalization. Our analysis of relevance maps confirms that ViTs with ISA exhibit sharper, more localized focus on object-relevant regions while reducing distractions from non-relevant (background) features, enabling more reliable models. We release our code at https://github.com/prdvanderwal/inhibited-self-attention

视觉变换器(Vision Transformers, ViTs)在计算机视觉任务中表现出色。然而,它们的自注意力机制常常将注意力分散到背景区域,依赖于虚假的相关性而非与物体相关的线索。受到生物视觉系统中观察到的抑制机制的启发,我们提出了抑制自注意力(Inhibited Self-Attention, ISA),这是一种新颖的自注意力机制,整合了抑制信号以增强特征选择性并抑制虚假响应。与传统的自注意力机制仅依赖于正向注意值(由于softmax归一化)不同,我们的方法保留并利用负向注意分数,以抑制无关特征并聚焦于感兴趣的物体。在多个数据集(包括ImageNet-1k和COCO)及若干鲁棒性基准测试中的实验表明,ISA增强了以物体为中心的选择性,减少了对捷径的依赖,并改善了分布外泛化。我们对相关性图的分析确认,具有ISA的ViTs在与物体相关的区域上表现出更尖锐、更局部的关注,同时减少了来自无关(背景)特征的干扰,从而使模型更加可靠。我们的代码已发布在 https://github.com/prdvanderwal/inhibited-self-attention

Abstract
Building capable embodied agents requires not only multimodal perception and understanding, but also agentic capabilities for reasoning about actions, adapting to evolving situations, and interacting with the physical world. In this report, we introduce Hy-Embodied-VLM-1.0, an efficient and powerful embodied foundation model specifically designed for embodied agents operating in the physical world. To cultivate such capabilities from the pre-training stage onward, we define an action-centric capability taxonomy comprising three progressive dimensions: Action-Relevant State Understanding, Action-Transition Reasoning, and Sequential and Adaptive Reasoning. Guided by this taxonomy, we develop a systematic data pipeline and curate data mixtures spanning both pre-training and post-training. To deliver strong physical-world understanding and interaction capabilities while supporting latency-sensitive deployment, we build our model on the Hy3-A3B language backbone and the Hy-ViT2 vision encoder. Its efficient Mixture-of-Experts architecture combines strong model capacity with high inference efficiency. We evaluate Hy-Embodied-VLM-1.0 on a comprehensive suite of 38 benchmarks covering embodied perception, physical-world understanding, and embodied reasoning. The model achieves the best performance among similarly sized models on 19 of the 38 benchmarks and substantially outperforms strong competitors, including Qwen3.6-A3B and Cosmos 3. Compared with the previous-generation Hy-Embodied-0.5 MoT-2B, Hy-Embodied-VLM-1.0 improves average performance by 8.4%. Despite activating only 3B parameters, it achieves performance close to that of the previous-generation model with 32B activated parameters. Beyond static benchmark evaluation, Hy-Embodied-VLM-1.0 also demonstrates strong performance on embodied agentic tasks requiring multi-turn interaction and long-horizon reasoning.

UniMedSeg: Unified In-Context Learning for Multi-Paradigm 2D/3D Medical Image Segmentation
UniMedSeg:用于多范式2D/3D医学图像分割的统一上下文学习
Abstract
Medical image segmentation foundation models are expected to generalize across diverse clinical scenarios, yet existing universal methods remain fragmented by prompt paradigms and spatial dimensions. Visual in-context learning, interactive segmentation, and language-guided segmentation are typically handled by paradigm-specific models, while 2D and 3D images are also modeled separately. Such isolation prevents heterogeneous annotations and data from being jointly absorbed by a single scalable model and limits cross-paradigm knowledge transfer. To address this bottleneck, we propose UniMedSeg, a Transformer-centric universal segmentation framework that maps visual examples, geometric interactions, language instructions, and 2D/3D images into a shared sequence space, enabling heterogeneous medical supervision to be jointly learned through a unified in-context interface without prompt- or dimension-specific branches. To overcome the long-sequence memory bottleneck caused by visual contexts, we introduce Decoupled Split Attention, which reduces attention complexity to linear while preserving hardware-friendly computation and focused context-target interaction. Extensively trained and evaluated on a large corpus curated from 27 public datasets, UniMedSeg achieves state-of-the-art performance across visual in-context, interactive, and language-guided segmentation without task-specific fine-tuning, demonstrating strong generalization on diverse held-out tasks. The code and model weights are publicly available at https://github.com/Lii1228/UniMedSeg

Rank-1 Identity Consensus Predicts Gallery Enrollment in 1:N Face Matching More Accurately than Score Thresholding
Rank-1身份共识比得分阈值更准确地预测1:N人脸匹配中的图库注册
Abstract
In operational 1:N face identification, a crucial question arises for each probe: is this person enrolled in the gallery or not? The stakes are high and asymmetric. Rejecting a mate-present (MP) probe loses a valid lead; accepting a mate-absent (MA) probe makes every returned candidate a false identification, at worst a wrongful arrest. Most approaches threshold match scores, but scores shift substantially with image quality and gallery size and composition, making thresholds fixed before deployment brittle under realistic conditions. Our prior work introduced 1-consistency, the only method based on rank consensus across multiple independently trained matchers: a probe is labeled MP if all matchers return the same rank-1 identity. This work stress-tests 1-consistency across 36 (gallery, probe quality) scenarios spanning four quality levels and two structural axes: images per identity and total enrolled identities. We benchmark against two score-thresholding methods that bracket what any deployed threshold could achieve. Fixed Score-Thresholding (FST), calibrated once on baseline conditions, collapses asymmetrically as quality degrades: MP recall falls below 2% while MA recall holds near 100%. Oracle Score-Thresholding (OST), re-tuned per scenario, is the best any threshold could theoretically do, yet for degraded probes 1-consistency matches it with zero tuning. The two differ mainly in error type (OST favors MP recall, 1-consistency favors MA recall), but on one axis 1-consistency does not merely match the oracle: when it labels a probe MP, it returns the correct mate 97-100% of the time versus OST's 66-84% under severe degradation. In short, 1-consistency delivers oracle-level accuracy without the impossible requirement: it sets no threshold, so it needs no advance knowledge of the conditions a probe will arrive in, which is what makes it usable.

在操作性的1:N人脸识别中,每个探测样本面临一个关键问题:此人是否已注册在图库中?风险高且不对称。拒绝一个存在配偶(MP)的探测样本会失去一个有效线索;而接受一个不存在配偶(MA)的探测样本则使得每个返回的候选者都成为错误识别,最严重的情况可能导致错误逮捕。大多数方法采用阈值匹配得分,但得分会因图像质量、图库大小和构成而显著变化,使得在实际条件下预先设定的阈值变得脆弱。我们之前的工作引入了1-一致性,这是唯一基于多个独立训练的匹配器之间的排名共识的方法:如果所有匹配器返回相同的排名-1身份,则将探测样本标记为MP。本研究在36种(图库、探测质量)场景下对1-一致性进行了压力测试,涵盖四个质量水平和两个结构轴:每个身份的图像数量和总注册身份数。我们与两种得分阈值方法进行了基准测试,这些方法界定了任何部署阈值可能达到的范围。固定得分阈值(FST)在基线条件下校准一次,随着质量下降而不对称崩溃:MP召回率降至2%以下,而MA召回率保持在接近100%。每种场景重新调整的神谕得分阈值(OST)是理论上任何阈值能够达到的最佳效果,但对于降级的探测样本,1-一致性在没有任何调整的情况下与之匹配。这两者主要在错误类型上有所不同(OST偏向于MP召回,1-一致性偏向于MA召回),但在一个轴上,1-一致性不仅仅是与神谕匹配:当它将探测样本标记为MP时,它返回正确配偶的概率为97-100%,而OST在严重降级下的概率为66-84%。简而言之,1-一致性在没有不可能要求的情况下提供了神谕级的准确性:它不设定阈值,因此不需要提前了解探测样本将到达的条件,这使得它可用。

Open-KNEAD: Knowledge-grounded Nutrition Estimation via Agentic Decomposition
Open-KNEAD:基于知识的营养估计通过主动分解
Abstract
Multimodal Large Language Models (MLLMs) are increasingly used for dietary assessment from meal images, where retrieval-augmented grounding was shown to sharpen nutrition estimates. However, we find this premise no longer holds for current MLLMs. A modern MLLM's direct estimate now matches or surpasses the full retrieval pipeline. This raises a question: if retrieval no longer improves the overall estimate, can it still deliver the two things clinicians value, accurate portions and a traceable, item-by-item record? We pursue this while preserving what matters for clinical adoption: minimal user burden (a single, unannotated meal image), explainability (an auditable record), and privacy (locally hosted inference). We introduce Open-KNEAD, a knowledge-grounded agentic framework for meal nutrition estimation that is training-free and locally deployable. Each decomposed food item is grounded to a Food and Nutrient Database for Dietary Studies (FNDDS) code via selective, nutrient-aware retrieval, composing an auditable per-item record. Across two open MLLM families and three cuisines, Open-KNEAD improves portion estimates over both prior grounding methods and direct estimation in most backbone-dataset settings. An agent-internal recipe-prior step further recovers the invisible cooking-added energy that biases estimates on non-US cuisine. The advantage is largest on the dietitian-verified ACETADA dataset, where the local open agent surpasses the direct portion estimates of two frontier closed models by roughly $30\%$ and $53\%$, all while keeping every meal image on local hardware. We release the Open-KNEAD framework and its agent-ready FNDDS knowledge base.

Domain-Incremental Remote Sensing Change Detection via Difference-Guided Adaptation and Frequency-Decoupled Distillation
基于差异引导适应和频率解耦蒸馏的领域增量遥感变化检测
Abstract
Remote sensing change detection (RSCD) models are prone to catastrophic forgetting when incrementally adapted to new domains. Existing domain-incremental learning (DIL) methods mainly preserve image-level representations but often overlook bitemporal discrepancy cues, which are critical for robust change detection under domain shifts. To address this limitation, we propose DG-FDD, a domain-incremental change detection framework that integrates Difference-Guided Adaptation and Frequency-Decoupled Distillation. Specifically, the Difference-Guided Dynamic Adapter (DGDA) models bitemporal feature discrepancies to promote change-aware feature adaptation and reduce domain-specific interference. Meanwhile, the Frequency-Decoupled Knowledge Distillation strategy with Cross-domain Synthesis (FDKD-CS) separates structural information from domain style in the frequency domain, enabling stable knowledge transfer without historical data. Extensive experiments on three public high-resolution RSCD datasets under two- and three-domain incremental protocols demonstrate that DG-FDD effectively mitigates catastrophic forgetting. Compared with independently trained single-task models, DG-FDD records mean relative changes in F1 and IoU of only -0.23% and -0.45%, respectively, across six two-domain sequences, and -0.69% and -1.31%, respectively, across the three evaluated three-domain sequences. These results indicate a favorable stability-plasticity balance between historical knowledge retention and new-domain adaptation in continual cross-domain change detection.

Abstract
Point tracking in surgery is crucial to enable applications in downstream tasks such as segmentation, 3D reconstruction, virtual tissue landmarking, autonomous probe-based scanning, and subtask autonomy. This paper introduces the 2025 iteration of a point tracking challenge to address this, wherein participants submit their algorithms for quantification. Their algorithms are evaluated using a dataset named surgical tattoos in infrared (STIR), with the challenge named the STIR Challenge 2025 (STIRC2025). The STIR Challenge 2025 comprises two quantitative components: accuracy and efficiency. The accuracy component tests the accuracy of algorithms on in vivo and ex vivo sequences. The efficiency component tests algorithm inference latency. The challenge was conducted as a part of MICCAI EndoVis 2025, and seven teams participated in this challenge. In this paper we summarize the challenge results and participant methods. The challenge dataset is available at: https://zenodo.org/records/20191078, and the code for baseline models and metrics calculation is available here: https://github.com/athaddius/STIRMetrics

ViCo3D: Empowering LiDAR-based Collaborative 3D Object Detection with Vision Foundation Models
ViCo3D:基于LiDAR的协作3D物体检测与视觉基础模型的结合
Abstract
LiDAR-based collaborative 3D perception in Vehicle-to-Everything (V2X) systems typically relies on fusing bird's-eye-view (BEV) features across agents. However, current BEV representations, typically extracted by LiDAR backbones trained from scratch, are geometry-dominated and lack general semantic priors, inherently limiting the efficacy of feature-level collaboration. Meanwhile, vision foundation models (VFMs) pretrained on large-scale image data have demonstrated strong capability in learning general-purpose and informative visual representations for 2D tasks, and have the potential to enhance agent-wise LiDAR BEV representations for collaboration. Despite this potential, adapting VFMs to LiDAR-based 3D detection remains challenging due to the substantial image-point cloud modality gap. To bridge this gap, we propose ViCo3D, a collaborative 3D object detection framework powered by VFMs. Specifically, ViCo3D adapts VFMs to LiDAR-based collaborative perception from three aspects: First, ViCo3D projects point clouds onto the BEV plane as three-channel images, enabling DINOv2 to extract BEV-space visual features from LiDAR inputs. Besides, to effectively integrate these DINOv2-derived features with LiDAR geometric features, ViCo3D introduces a multi-scale BEV fusion module within the single-agent encoder. In addition, ViCo3D adopts an ego-centric cross-agent fusion strategy to aggregate complementary information from multiple agents. Experiments on DAIR-V2X and V2XSet demonstrate that ViCo3D achieves state-of-the-art 3D detection performance. Remarkably, it delivers up to 1.8x greater collaborative gains than prior methods on DAIR-V2X. The code will be made public available for future investigation.

基于LiDAR的协作3D感知在车对一切(V2X)系统中通常依赖于跨代理融合鸟瞰图(BEV)特征。然而,目前的BEV表示通常由从头训练的LiDAR骨干网络提取,主要受几何特征主导,缺乏通用的语义先验,这在本质上限制了特征级协作的有效性。同时,在大规模图像数据上预训练的视觉基础模型(VFMs)在学习通用和信息丰富的视觉表示方面表现出强大的能力,能够增强代理间的LiDAR BEV表示以实现协作。尽管存在这种潜力,但将VFMs适应于基于LiDAR的3D检测仍然面临挑战,因为图像与点云之间存在显著的模态差距。为了解决这一问题,我们提出了ViCo3D,这是一种由VFMs驱动的协作3D物体检测框架。具体而言,ViCo3D从三个方面将VFMs适应于基于LiDAR的协作感知:首先,ViCo3D将点云投影到BEV平面上,形成三通道图像,使DINOv2能够从LiDAR输入中提取BEV空间视觉特征。此外,为了有效地将这些DINOv2派生的特征与LiDAR几何特征整合,ViCo3D在单代理编码器中引入了多尺度BEV融合模块。此外,ViCo3D采用了一种以自我为中心的跨代理融合策略,以聚合来自多个代理的互补信息。在DAIR-V2X和V2XSet上的实验表明,ViCo3D实现了最先进的3D检测性能。值得注意的是,在DAIR-V2X上,它比之前的方法提供了高达1.8倍的协作增益。代码将公开以供未来研究使用。

Controllable Generation of Diverse Dermatological Imagery for Fair and Efficient Malignancy Classification
可控生成多样化皮肤病影像以实现公平高效的恶性肿瘤分类
Abstract
Accurate dermatological diagnosis naturally necessitates equitable performance across diverse populations, yet a systematic lack of expertly annotated images, especially for underrepresented skin tones and rare diseases, impedes progress toward measurably fair methods. We introduce cgDDI (Controllable Generation of Diverse Dermatological Imagery), a hybrid framework that (1) synthesizes realistic healthy skin samples without disturbing other input properties, (2) maps single-sample rare lesions onto novel skin-tones and locations non-parametrically, and (3) allows for efficient parametric generation with as few as 10 training samples. The framework supports both human and automated segmentation masking, enabling scalability to datasets without pre-made lesion masks. We grow a 656-image dataset by more than 400x and validate across two datasets: biopsy-confirmed Diverse Dermatology Images (DDI) and expert-verified Fitzpatrick17k (F17k). On the DDI benchmark, we achieve malignancy classification accuracy of 86.4% under synthetic-only training and 90.9% state-of-the-art performance with real data fine-tuning, alongside leading fairness metrics. Cross-dataset experiments show +13.9% accuracy improvements on unseen F17k data despite minimal disease overlap. We openly release 266k+ synthetic images, code, and generative models to further support fairness research at https://github.com/hectorcarrion/ControllableGenDDI.

X-Lens: Real-Time Metric Depth Estimation with Heterogeneous Cameras
X-Lens:基于异构相机的实时度量深度估计
Abstract
We present X-lens, a compact feed-forward model for metric depth estimation from a variable number of calibrated fisheye and pinhole views. To support real-time downstream perception, X-lens is built around a geometry-aware heterogeneous camera formulation with two key components. Learnable calibration tokens provide a coarse alignment between fisheye and pinhole projective spaces, while a Jacobian-parameterized distortion bias injected into cross-attention models local projection changes and promotes cross-camera consistency, enabling robust generalization with only 0.04B parameters and up to 41 FPS. The model predicts dense depth together with a global metric scale, avoiding auxiliary reconstruction targets that increase computation and optimization complexity. To learn such cross-camera generalization at scale and depth, X-lens is trained on multiple public datasets and OmniScene, our newly released large-scale synthetic dataset containing approximately 266K synchronized six-view frames, 1.7M individual images, and 103 indoor and outdoor scenes. Extensive experiments on both real-world and synthetic indoor and outdoor datasets demonstrate superior heterogeneous-camera metric depth accuracy, reducing AbsRel by 25.4\% on OmniScene-Full over the strongest baseline while using 88.9\% fewer parameters, with competitive performance on conventional fisheye-only and pinhole-only settings.

DermDepth: Toward Monocular Metric Scale 3D Reconstruction Models for Dermatology
DermDepth:面向皮肤病学的单目度量尺度三维重建模型
Abstract
Dermatological practice routinely involves measuring and tracking lesion size, morphology and texture, as critical components of wound or skin cancer screening, monitoring and diagnosis. To accomplish this task, practitioners often image the skin surface with commonly available off-the-shelf camera sensors. This has led to an overwhelming research focus on 2D methods while these objectives naturally benefit from 3D information. In this paper, we demonstrate that dense monocular 3D reconstructions, metric scale measurements and rich surface normal texture estimates are achievable for both dermoscopic and macroscopic cases without the need for additional hardware or multiple captures. We present DermDepth, the first single-view metric scale 3D model for the dermatological domain and D-Synth, the first synthetic dermoscopic dataset with pixel-perfect 3D information. Our experiments show training DermDepth on D-Synth corrects metric scale error from over 16x to under 1.1x for real dermoscopic data, while preserving geometric quality and increasing texture richness. Fine-tuning on a small amount of real clinical samples generalizes our method across three real-world benchmarks spanning the few mm to hundred cm range, diverse skin-tones, chronic wound cases and produces measurements broadly consistent with disease size reported in medical literature.

皮肤科实践通常涉及测量和跟踪病变的大小、形态和纹理,这些都是伤口或皮肤癌筛查、监测和诊断的关键组成部分。为了完成这一任务,医生通常使用常见的现成相机传感器对皮肤表面进行成像。这导致了对二维方法的过度研究,而这些目标自然受益于三维信息。在本文中,我们展示了在不需要额外硬件或多次捕获的情况下,密集的单目三维重建、度量尺度测量和丰富的表面法线纹理估计在皮肤镜和肉眼观察情况下都是可以实现的。我们提出了DermDepth,这是皮肤病学领域第一个单视图度量尺度三维模型,以及D-Synth,这是第一个具有像素完美三维信息的合成皮肤镜数据集。我们的实验表明,在D-Synth上训练DermDepth可以将真实皮肤镜数据的度量尺度误差从超过16倍降低到1.1倍以下,同时保持几何质量并增加纹理丰富性。在少量真实临床样本上进行微调使我们的方法在三个真实世界基准上具有良好的泛化能力,涵盖从几毫米到数百厘米的范围、多样的肤色和慢性伤口案例,并产生与医学文献中报告的疾病大小大致一致的测量结果。所有代码、数据和模型均可在https://github.com/hectorcarrion/dermdepth获取。

We develop a rigorous theoretical framework for optimal market making in perpetual futures markets with zero maker fees. We model the market maker's problem as a stochastic optimal control problem on a filtered probability space, where the controls are adaptive bid-ask spreads and inventory hedging decisions across two exchanges. Our contributions include: (i) a PnL decomposition theorem separating revenue into spread income, adverse selection loss, inventory carrying cost, hedging friction, and funding rate exposure; (ii) the Hamilton-Jacobi-Bellman equation for the joint spread-inventory-hedging control problem under CARA utility with a verification theorem; (iii) High-APY Regime Theorems characterizing profitable regions via five dimensionless parameters, culminating in a Master APY Formula; (iv) analysis of zero-fee economics on decentralized perpetual exchanges with optimal entry-exit thresholds; (v) optimal cross-exchange hedging policies with funding rate dynamics and a hedge regime trichotomy; (vi) a robustness margin quantifying parameter uncertainty tolerance; (vii) exponential drawdown probability bounds and a universal APY-VaR identity; (viii) ergodic inventory distribution under optimal control with Bayesian adaptive estimation; (ix) Kelly-optimal leverage with ruin boundaries; and (x) multi-pair portfolio allocation with diversification saturation results. Numerical analysis with twenty-three figures reveals phase transitions between profitable and unprofitable regimes. Our framework unifies and extends the Avellaneda-Stoikov, Gueant-Lehalle-Fernandez-Tapia, and Glosten-Milgrom paradigms for modern decentralized venue microstructure.

In-Context Reinforcement Learning under Non-Stationarity: A Survey
非平稳环境下的上下文强化学习:综述
Abstract
The development of decision-pretrained transformers, algorithm distillation, long-context meta-RL, and retrieval-augmented agents has renewed interest in in-context reinforcement learning (ICRL): the ability of a pretrained or fine-tuned decision model to infer latent task rules and improve future behavior from interaction context, without test-time parameter updates. This line of work asks when trial-and-error evidence, rewards, transitions, demonstrations, feedback, or retrieved experience can make learning-like computation happen inside the context window. However, existing surveys of ICRL mainly organize the field around pretraining objectives, architectures, context formats, evaluation protocols, and theoretical mechanisms, while the non-stationary setting remains comparatively underexamined. In changing environments, accumulated context is not merely more evidence about a fixed task: the reward specification, transition kernel, observation channel, action interface, constraint model, or demonstration and memory distribution can fall out of alignment with the current regime. Previously useful context can therefore become stale, misleading, or useful again when an old regime returns. We survey non-stationary ICRL as the problem of adapting through context while deployed policy parameters remain fixed: the policy must infer both the current decision rule and which parts of its accumulated evidence still support that rule. We define non-stationary ICRL, relate it to meta-RL, decision sequence modeling, retrieval-augmented RL, value- and model-aware ICRL, and reward-feedback agents, and organize the literature along three questions: what changes, how the change unfolds, and how observable the change is to the agent.

Ontology-Amplified Distillation and Contextuality Auditing for Sovereign Enterprise Language Models: A Combined Proof-of-Mechanism and Negative-Results Method Study
本体增强蒸馏与情境审计在主权企业语言模型中的应用:结合机制证明与负结果的方法研究
Abstract
Regulated financial institutions operating under data-residency rules need tenant-owned language models that can run inside the institution's perimeter. This paper combines two related FAOS studies into one mechanism-and-control article. First, it reports a reduced-power proof-of-mechanism study of ontology-amplified distillation: a Qwen3.6-27B student is adapted to the Foundation AgenticOS ontology through supervised fine-tuning on frontier-teacher trajectories and ontology-grounded direct preference optimization (DPO), trained locally on a single Apple M5 Max from 47 synthetic, English-language, cross-domain preference pairs. On 40 held-out Vietnamese financial-domain tasks, the distilled student grounds 36 of 40 tasks (grounded rate 0.90; mean ontology term-coverage r_onto = 0.95 on a metric floored at 0.50), equal to the GPT-5 frontier baseline, which also grounds 36 of 40. The outcome is underpowered to establish equivalence: the paired-difference 95% confidence interval spans +/-4 tasks, and the run does not test or show the pre-registered amplification prediction that the student should exceed the frontier. Second, the paper consolidates a contextuality-audit method for enterprise-agent routing. In a separate negative-results pilot, the corrected canonical Contextuality-by-Default degree is zero for all Phase 1.3 groups in both the local-Qwen run and an explicitly labeled Gemma replication check; the useful signal is direct influence and construct coupling, not surviving residual contextuality. Together, the studies pair an ontology-grounded model-building mechanism with a governance diagnostic for deciding when apparent disagreement should trigger prompt standardization, multi-agent synthesis, or human review. The evidence supports neither deployability, safety, superiority, statistical equivalence, nor a contextuality-positive routing rule.

GRID: Grammar-Railed Decoding for Enterprise SQL Generation
GRID:用于企业 SQL 生成的语法约束解码
Abstract
Large language models can write SQL, but enterprise deployment demands more than plausible text: outputs must be syntactically valid, must respect per-role and per-schema policy, must carry provable (not best-effort) guarantees, must not slow down as generations grow, and must leave a compliance-grade record of every decision. We present GRID (Grammar-Railed Decoding), a grammar-constrained decoding engine that keys exact next-token masks on parser configurations (lexer scan state x LALR(1) stack) rather than on token sequences, and uses the incrementally advanced LALR(1) parser itself as a viable-prefix oracle. LLM tokens are bridged to grammar terminals by a byte-level trie walk with a context-independent/context-dependent split that makes cache-key soundness hold by construction. Role-based access control is compiled into the language: role projections subset the grammar's productions and schema lexicons restrict identifier terminals, so forbidden verbs and identifiers are unreachable at mask level. Four guarantees (soundness, completeness, termination, and near-constant per-token cost) are stated with explicit preconditions and each paired with a test or benchmark. Rust kernels bring the per-token mask to a 3.6-6.7 us median, ahead of llguidance at p50 and p90 on two tokenizers with zero false rejects; per-token guard cost is position-flat at n=16,000. On Spider, constrained decoding is worth +13 execution-accuracy points at 0.5B, and one checker-guided repair pass over the provably mask-unenforceable residue (column-level policy) lifts a 7B model to 94.5% executable. A hash-chained per-token audit trail replays bit-identically with 100% tamper detection. We state plainly what the mask cannot do (distribution faithfulness, column-level RBAC, non-LALR(1) languages) and where measured cost remains.

大型语言模型能够编写 SQL,但企业部署的要求不仅仅是合理的文本:输出必须在语法上有效,必须遵循每个角色和每个模式的策略,必须提供可证明的(而非尽力而为的)保证,随着生成的增加不能减慢,并且必须保留每个决策的合规记录。我们提出了 GRID(语法约束解码),这是一种语法约束的解码引擎,它基于解析器配置(词法分析器扫描状态 x LALR(1) 堆栈)而非基于令牌序列来确定确切的下一个令牌掩码,并使用逐步改进的 LALR(1) 解析器本身作为可行前缀的预言者。LLM 令牌通过字节级前缀树遍历与语法终端连接,采用上下文无关/上下文相关的分割,使得缓存键的有效性在构造上得以保持。基于角色的访问控制被编译到语言中:角色投影子集语法的产生和模式词汇限制标识符终端,因此在掩码级别上无法访问被禁止的动词和标识符。我们明确陈述了四个保证(有效性、完整性、终止性和近似常数的每令牌成本),并为每个保证提供了明确的前提条件,并与测试或基准配对。Rust 内核将每个令牌的掩码处理时间缩短至 3.6-6.7 微秒的中位数,在两个令牌生成器上,p50 和 p90 的性能优于 llguidance,且没有虚假拒绝;每个令牌的保护成本在 n=16,000 时保持平坦。在 Spider 上,约束解码在 0.5B 时增加了 +13 的执行准确度,并且对可证明的掩码无法强制执行的残余(列级策略)进行一次检查器引导的修复,使得 7B 模型的可执行性提升至 94.5%。哈希链式的每个令牌审计记录以 100% 的篡改检测以位相同的方式重放。我们明确说明了掩码无法实现的内容(分布忠实性、列级 RBAC、非 LALR(1) 语言)以及测量成本仍然存在的地方。

Calibration-First Reward-Component Auditing for Reinforcement Learning Control in Smart Greenhouses
基于校准的强化学习控制在智能温室中的奖励组件审计
Abstract
Greenhouse reinforcement learning can test climate-control ideas at a speed and scale that is difficult to achieve with crop experiments alone. For smart-greenhouse control, however, a single simulator return is not enough: a grower or control engineer also needs to know when the policy heats, enriches CO2, vents, manages humidity, deploys screens, or uses lamps.We propose a reproducible calibration-first reward audit framework that keeps named greenhouse-control reward components comparable across simulator training, facility-adapted rollouts, logged Autonomous Greenhouse Challenge records, and actuator-rule distillation. In GreenLight-Gym, the framework decomposes the scalar reward into conditional temperature, CO2, humidity and vapor-pressure-deficit, screen, and actuation-proxy terms; adapts GreenLight to the second Autonomous Greenhouse Challenge logged climate traces; and scores the same components on logged greenhouse data.

Optimization Is Not All You Need
优化并不是你所需要的一切
Abstract
In 2019, OpenAI released two million GPT-2 outputs-ungrammatical, half broken-to aid the detection of machine-generated text. The alignment that produced their more fluent successors is usually regarded as an engineering achievement; we read it instead as the newest expression of optimization culture: the conviction, older than the technology, that measurable improvement along predefined axes exhausts the question of value. Tracing that conviction through the stack-pretraining, decoding, preference tuning, benchmarking, interface-and back through its genealogy in the audit society, we arrive at the limit: an optimization procedure can measure how improbable a piece of generated text is; it cannot tell whether that unlikelihood is error or invention. A procedure that cannot make that distinction has nonetheless, within half a decade, assumed the authority to set the protocols of legitimate language. Held for centuries by academies and schoolrooms, grammars and examiners, this authority has been given over to loss functions, reward models, benchmarks, and system prompts: an apparatus that executes the office of judgment with no capacity for judging.

LP Mining with LP2Graph: A Use Case for Railway Rescheduling
使用 LP2Graph 进行线性规划挖掘:铁路调度重排的应用案例
Abstract
Like many optimization-driven domains, railway rescheduling relies on Mixed-Integer Linear Programming (MILP), yet the field's modeling knowledge is scattered across hundreds of papers in incompatible notations, and narrative surveys organize it subjectively: they classify models by vocabulary rather than by structure, and reproduce neither. We present LP Mining with LP2Graph, a method that mines the structure of published LP and MILP formulations into a reproducible dataset and an induced taxonomy. Its core, LP2Graph, represents each formulation admitted by its canonical grammar as a typed variable--equation graph derived from a single canonical model; once a source is extracted into that model, everything downstream is deterministic. Each source is parsed into this model, homologized, and clustered bottom-up (over variables, then constraints and the objective, then whole-model structure) and, separately, by application domain and solution approach; the resulting groups are labeled by a rule-seeded, self-updating classifier. We validate the representation rather than assume it: per-cluster representatives are regenerated as independent LaTeX and re-solved across CBC, HiGHS and Gurobi against the optimum reported in the source paper. The outcome is an objective, repeatable taxonomy of variables, constraints and model types: the principled foundation on which our raiLPminer line of automated railway-rescheduling model development builds.

Designing Agent-Ready Websites for AI Web Agents: A Framework for Machine Readability, Actionability, and Decision Reliability
为人工智能网络代理设计代理友好型网站:机器可读性、可操作性和决策可靠性的框架
Abstract
Online shopping is increasingly shifting toward a model in which AI agents independently search for products, compare options, evaluate constraints, and carry out parts of the purchasing process for users. Website design must now support both human and agent-mediated interaction. This paper introduces the agent-ready website, a design framework for enhancing the readability, interpretability, verifiability, and actionability of e-commerce platforms for AI agents. Existing web design, SEO, and generative engine optimization (GEO) metrics do not fully assess a website's capacity for agent-mediated interaction. The proposed framework is structured around three dimensions agent interpretability, agent executability, and agent decision reliability supported by features such as machine readability, semantic clarity, agent actionability, and contextual decision-reliability signals. The framework is evaluated through a controlled experiment comparing a human-oriented baseline and an agent-ready version of an identical website prototype, with identical catalogs, pricing, stock, and shopping workflows. The evaluation involved five tasks, three browser-agent models (GPT-4.1, Gemini-2.5 Flash, and Grok-4 Fast), and 300 runs, measuring PASS,PARTIAL,FAIL outcomes, strict and functional success rates, error patterns, step counts, and token consumption. The agent-ready website achieved 134 PASS runs out of 150 versus 74 out of 150 for the baseline (strict success rates of 89.3% vs. 49.3%), with the largest gains in product detail extraction, comparison, and multi-constraint selection. It also reduced PARTIAL outcomes from 43 to 3 and lowered the average step count from 9.31 to 6.49. These results provide preliminary evidence that enhanced structural clarity, action cues, evidence signals, and temporal validity indicators can substantially improve the reliability and efficiency of AI browser agents.

Graph Feedback Controls Consensus and Clique Formation in Open-Weight Language-Model Populations
图反馈控制开放权重语言模型群体中的共识与团体形成
Abstract
Multi-agent language-model systems increasingly route local interactions, yet the runtime interaction graph is often treated as an implementation detail. We study convention formation in open-weight LM populations spanning 1.1B-32B parameters with a naming-game protocol. Restricted first-token scores over tokenizer-safe labels let us measure prompt-conditioned score-state distributions, construct state-similarity graphs, and separate sampled-label agreement from latent state-space consensus. Across controlled interventions, in the main open-weight repair grids, retained partner-label evidence is necessary but not sufficient: homophilous threshold-similarity routing deletes cross-basin exposure and amplifies fragmentation, while bridge-seeking routing often repairs fragmentation when memory is available. In a three-seed mixed four-model grid, threshold-similarity produces no final behavioral or state consensus in 189 setting-seed runs, whereas state-component and label-disagreement bridges recover final behavioral consensus in 14/18 retained-memory runs. Across homogeneous model populations, retained history generally shifts fragmented dynamics toward consensus; the clearest case is Qwen2.5-32B, which reaches stable behavioral and final state consensus in all 18 retained-history well-mixed settings, while threshold-similarity reaches neither form of consensus in 189 settings. Robustness over state thresholds, population size, and vocabulary size preserves the qualitative ordering, and early-window graph-energy features provide useful within-grid diagnostics.

Operationalising Multi-Dimensional Evaluation for Conversational Agents: A Scalable, Governed Pipeline with Selective Re-evaluation and Model Benchmarking
为对话代理实现多维评估的操作化:一个可扩展的、受管控的管道,具有选择性重新评估和模型基准测试
Abstract
Evaluating retail conversational agents requires methods beyond lexical-overlap metrics to assess intent alignment, factuality, helpfulness, clarity, tone, and overall response quality. Although LLM-as-a-judge methods provide scalable alternatives to human evaluation, production deployment introduces challenges in governance, reproducibility, cost, schema consistency, traceability, and reliability. We present GenAI Evaluation, a governed, configuration-driven pipeline for large-scale evaluation of retail conversational systems. It processes production chatbot logs through normalization, sharding, asynchronous execution, and schema-constrained LLM scoring. The framework evaluates helpfulness, truthfulness, clarity, tone alignment, and translation-specific dimensions. Selective re-evaluation processes only incomplete, malformed, or schema-invalid records, while schema locking, versioned configurations, validation logs, and record-level provenance support auditability. The framework processes approximately 50,000 records daily and has evaluated more than two million interactions. Validation used 12,980 stratified-random human-labeled records from four trained annotators. Classification covered 14 intents, 156 sub-intents, 18 major domains, and 129 sub-domains. The pipeline achieved a macro F1 score of 0.93 and 89% human-acceptability accuracy for translation.

Representing and Generating Levels Over Time through Playtrace Reconstructive Partitioning
通过 Playtrace 重构分区表示和生成随时间变化的关卡
Abstract
Video games are a dynamic medium experienced over time. While there are many Procedural Content Generation (PCG) approaches for generating video game levels, they often use representations that abstract away this dynamic nature. In this paper, we introduce a novel, domain-independent ``cake'' representation for game levels over time which implicitly encodes dynamic information. We present a novel level generation approach Playtrace Reconstructive Partitioning (PRP) specifically developed for this cake representation. We compare against six state-of-the-art PCG approaches in the game domain of \textit{Sokoban}, and find that our approach can generate valid levels without sacrificing solution diversity. We believe our cake representation more neatly encodes the implicit dynamic nature of games compared to existing representations, which allows for our domain-agnostic level generation algorithm PRP.

Connected by Construction: Learning Tractable Near-Tour Marginals for Traveling Salesman Problems
通过构造连接:学习可处理的近巡回边际以解决旅行商问题
Abstract
Learning-based methods for the traveling salesman problem (TSP) are often evaluated through the tours produced after decoding or search, but the learned object itself frequently lives in a surrogate space such as heatmaps, assignments, construction policies, or search-guidance scores. This hides the fundamental question: what Hamiltonian structure has actually been learned before decoding? In this study, we directly answer this question by learning TSP through a structurally meaningful latent object, rather than leaving most of the Hamiltonian structure to the final decoding stage. Based on a connected-by-construction rooted $1$-tree Gibbs family, we propose an end-to-end unsupervised learning pipeline called \emph{C2TSP}. The pipeline learns residual edge perturbations from unbiased TSP cost through implicit differentiation. For structural correction, a smoothed Held--Karp layer restores expected degree balance, while certificate-guided sharpening further pushes the connected distribution toward more tour-like structures. Experiments show that C2TSP yields strong decoding performance while preserving interpretable structural information. Ablations further verify that edge perturbation and certificate-guided sharpening jointly improve both tour cost and tour-like structure.

基于学习的方法解决旅行商问题(TSP)通常通过解码或搜索后生成的巡回路径进行评估,但学习的对象本身往往存在于诸如热图、分配、构造策略或搜索引导分数等代理空间中。这掩盖了一个根本性的问题:在解码之前,实际上学习到了什么样的哈密顿结构?在本研究中,我们通过学习一个结构上有意义的潜在对象直接回答了这个问题,而不是将大部分哈密顿结构留给最终的解码阶段。基于构造连接的根植于 $1$-树的 Gibbs 家族,我们提出了一种名为 extit{C2TSP} 的端到端无监督学习管道。该管道通过隐式微分从无偏的 TSP 成本中学习残余边缘扰动。为了进行结构修正,平滑的 Held-Karp 层恢复预期的度平衡,而证书引导的锐化进一步推动连接分布朝向更像巡回路径的结构。实验表明,C2TSP 在保持可解释的结构信息的同时,具有强大的解码性能。消融实验进一步验证了边缘扰动和证书引导的锐化共同改善了巡回成本和巡回路径结构。

The Emerging Paradigm of Geospatial Foundation Models: From Pre-Training to Agentic Reasoning
地理空间基础模型的新兴范式:从预训练到智能推理
Abstract
The analysis of satellite and aerial imagery has entered a new era with the advent of foundation models. This paper describes the concept of Geospatial Foundation Models (GeoFMs), which are artificial intelligence/machine learning (AI/ML) models pre-trained on massive geospatial datasets through varied methodologies. We first articulate the core paradigm shift that GeoFMs enable: a separation of duties, where large-scale model providers perform the computationally intensive pretraining, allowing domain experts to rapidly fine-tune or prompt these models for specific, mission-critical tasks. This approach democratizes access to state-of-the-art AI/ML while maintaining the security and confidentiality of the downstream task. We then explore the novel capabilities unlocked by different types of GeoFMs, distinguishing between the finetunable vision models produced by self-supervised techniques like masked auto-encoding, and the vision-language models produced by contrastive learning which enable zero-shot tasks like open-vocabulary image analysis. Next, we discuss the practical considerations for operationalizing GeoFMs, from performance-cost analysis to the broader MLOps ecosystem. To that end, we introduce a taxonomy of model adaptation strategies and propose a framework for domain experts to select the most cost-effective adaptation approach for their particular mission set. Finally, we present a forward-looking vision of Agentic Geospatial Reasoning, where Large Language Models act as intelligent orchestrators, leveraging GeoFMs as tools to answer high-level user queries in natural language and automate complex analytical workflows, moving the field from perception to cognition.

Cost-Governed RAG: Unified Per-Tenant Cost Attribution Across Retrieval and Generation in Multi-Tenant LLM Systems
成本治理的检索增强生成(RAG):多租户大语言模型系统中统一的每租户成本归属
Abstract
Enterprise Retrieval-Augmented Generation (RAG) deployments face a critical governance gap: while LLM generation cost is metered per token, the retrieval layer - vector memory, similarity compute, and embedding API calls - remains an unattributed shared cost, enabling invisible cross-subsidization among tenants. We present Cost-Governed RAG, an architecture that integrates a codebook-oblivious vector index (TurboVec) with a multi-tenant LLM governance gateway, creating a unified observability stack where embedding, retrieval, and generation costs are jointly attributable per tenant. The architecture exploits TurboVec's deterministic, closed-form memory formula to enable near-exact per-tenant retrieval cost calculation - a property unavailable in graph-based indexes with non-linear memory overhead. Deployed on Snowpark Container Services within a cloud data platform's governance boundary, the system achieves 99.96% end-to-end cost attribution accuracy across 100 simulated tenants (10M vectors, log-normal size distribution) with telemetry overhead below 0.04% of query latency. The architecture reduces retrieval infrastructure cost by 3.1-9.0x compared to managed vector database services under the pricing assumptions detailed in Section IV. We formalize a three-layer cost model and demonstrate that codebook-oblivious quantization enables deterministic per-tenant cost attribution while also removing the shared-codebook leakage surface present in trained quantizers - the latter observation being exploratory and subject to the limitations described in Section VII.

A Threshold Exceedance Framework for CBRN Uplift Evaluation in Frontier Language Models
前沿语言模型中CBRN提升评估的阈值超越框架
Abstract
As frontier language models advance, policymakers and model developers need methods for assessing whether model access materially increases a non-expert actor's ability to plan high-consequence Chemical, Biological, Radiological, or Nuclear (CBRN) misuse relative to public tools alone. Existing CBRN evaluations differ in non-expert definitions, threat scope, baselines, scoring rubrics, and decision rules, making results difficult to compare across studies. We introduce a Threshold Exceedance Criteria (TEC) framework that decomposes an uplift study into independently executable components: determining non-expert participant eligibility, defining the CBRN threat scope for the study, and statistically estimating material uplift. We then operationalize the TEC framework in a large-scale empirical study using a design that determines two forms of uplift: generative (where a model assists plan creation from scratch) and revisionist (where a model assists refinement of an existing plan). The study produced attack plans across the CBRN domains, which we evaluated through subject-matter-expert review to estimate generative and revisionist uplift. Applying the framework, our empirical study revealed domain heterogeneity: under this controlled pre-release evaluation, model-assisted plans sometimes received expert-equivalent instructional ratings, but confirmed material uplift was limited to the radiological domain. These findings informed mitigation and deployment-governance decisions rather than characterizing deployed model behavior. We conclude with methodological lessons for future CBRN uplift evaluations, emphasizing prespecified criteria, explicit baselines, separation of generative and revisionist estimates, and careful distinction between preliminary screening signals and confirmed risk determinations.

Rethinking the Evaluation of Harness Evolution for Agents
重新思考代理的自动化测试框架演化评估
Abstract
We revisit the evaluation of automatic harness evolution for LLM agents. Existing harness evolution methods use unit test cases to search for harness configurations and then report final performance on the same public benchmark. This protocol raises two fundamental concerns. First, harness evolution is itself an iterative search procedure that repeatedly evaluates and revises candidate harnesses using task feedback. As in agentic test-time scaling, it should therefore be compared with simple task-level search baselines under matched feedback and inference budgets to determine whether its gains arise from improved harness design or from additional search alone. Second, because the search and the final evaluation share the same benchmark, the reported gains risk overfitting to that specific task set. To address these concerns, we conduct an extensive evaluation comparing harness evolution with simple test-time scaling and discovery baselines under comparable feedback and inference budgets, and also evaluate evolved harnesses on held-out tasks to assess whether the discovered improvements generalize. Experiments on Terminal-Bench 2.1 with GPT-5.4 and Claude Opus 4.6 show that automatic harness evolution does not consistently outperform simple test-time scaling methods and exhibits limited generalization. Our results raise important questions about the effectiveness of automatic harness evolution and highlight the need for fairer evaluation protocols and benchmarks for automatic harness design.

我们重新审视了大型语言模型(LLM)代理的自动化测试框架演化评估。现有的测试框架演化方法使用单元测试用例来搜索测试框架配置,然后在同一公共基准上报告最终性能。这一协议引发了两个基本问题。首先,测试框架演化本身就是一个迭代搜索过程,它反复评估和修订候选测试框架,利用任务反馈。因此,应该在匹配的反馈和推理预算下,将其与简单的任务级搜索基准进行比较,以确定其收益是源于改进的测试框架设计,还是仅仅来自额外的搜索。其次,由于搜索和最终评估共享相同的基准,报告的收益存在过拟合于特定任务集的风险。为了解决这些问题,我们进行了广泛的评估,将测试框架演化与简单的测试时间缩放和发现基准进行比较,且在可比的反馈和推理预算下进行评估,同时还在保留任务上评估演化后的测试框架,以评估发现的改进是否具有泛化能力。在使用GPT-5.4和Claude Opus 4.6的Terminal-Bench 2.1上的实验表明,自动化测试框架演化并不总是优于简单的测试时间缩放方法,并且表现出有限的泛化能力。我们的结果提出了关于自动化测试框架演化有效性的重要问题,并强调了对自动化测试框架设计进行更公平的评估协议和基准的需求。我们的代码可在https://github.com/rethinking-harness-evolution获取。

On-Device Deep Research at 4B: Exposure Bounds Faithfulness, Retrieval Bounds Coverage
在4B设备上的深度研究:曝光限制影响可信度,检索限制影响覆盖率
Abstract
On-device research agents search a corpus, read sources, and write a cited brief on a personal laptop. Whether their citations are faithful, and at what cost, is unmeasured for a deployable small model. This study fixes one 4B generator on a 24 GB laptop and asks what makes its citations faithful. It separates two quantities usually reported as one number. Cited claim faithfulness asks whether the cited source supports the claim. Trustworthy coverage asks whether the agent also cites the right sources. The study crosses how much of each source the generator sees, 400 against 1500 characters, with the quality of the sources supplied, gold papers against retrieved papers. Two levers fall out, and they act on different outcomes. Exposure sets faithfulness. More of each source lifts faithfulness from 0.45 to 0.58 on retrieved sources and from 0.37 to 0.58 on gold sources, and the two settings converge, so faithfulness is bound by exposure, not by whether the source is correct. The exposure lift is robust to a second, independent judge; the exact convergence is tight under the primary judge and only approximate under the second. Retrieval sets coverage. Trustworthy coverage stays near 0.22 on retrieved sources at any exposure, because recall is held near 0.40, so exposure cannot fix which sources are cited. The extra exposure costs about 235 output tokens. The practical recipe is to raise per source exposure first, cheaply, and then treat retrieval recall as the only remaining lever.

How Many Tasks Are Enough for Agent Benchmark Decisions? A Replay Analysis of Public LLM Agent Benchmarks
代理基准决策需要多少任务?对公共大型语言模型代理基准的重播分析
Abstract
Agent benchmarks often compare two agents after all tasks have run, but costly evaluations make partial runs tempting. A task fraction alone does not show whether a partial run supports the same pairwise conclusion as the completed benchmark. We study this question by replaying completed public task-level records from SWE-bench, AppWorld, and tau-bench. A partial budget counts as enough only when it supports the completed benchmark's decision, covers required task groups, and leaves no more than a target fraction of comparisons unresolved. The required task fraction varies sharply. At the strict 0 percentage point threshold on a 5 percentage point budget grid, AppWorld first meets all targets at 15 percent, tau-bench at 25 percent, and SWE-bench Verified at 90 percent; SWE-bench Lite does not meet all targets by 95 percent under the primary coverage rule. Partial-evaluation reports should state how much one agent must outperform another, how tasks are selected, what coverage rule is required, what decision rule is used, and how many comparisons may remain unresolved.

代理基准通常在所有任务完成后比较两个代理,但高昂的评估成本使得部分运行变得诱人。仅凭任务比例无法表明部分运行是否支持与完成基准相同的成对结论。我们通过重播来自SWE-bench、AppWorld和tau-bench的已完成公共任务级记录来研究这个问题。只有当部分预算支持完成基准的决策、覆盖所需的任务组,并且未解决的比较不超过目标比例时,才算足够。所需的任务比例变化显著。在5个百分点预算网格的严格0个百分点阈值下,AppWorld在15%时首次满足所有目标,tau-bench在25%时满足,SWE-bench Verified在90%时满足;而SWE-bench Lite在主要覆盖规则下在95%时未能满足所有目标。部分评估报告应说明一个代理必须超越另一个代理的程度、任务选择的方式、所需的覆盖规则、使用的决策规则,以及可能未解决的比较数量。

PM-Bench: Evaluating Prospective Memory in LLM Agents
PM-Bench:评估大型语言模型代理的前瞻性记忆
Abstract
A significant challenge in agentic AI is prospective memory: the ability to execute an intention at a specific future cue or state while other activities are ongoing. We introduce PM-Bench, a text-based benchmark for measuring prospective memory capabilities in modern LLM agents. Inspired by the Virtual Week paradigm from cognitive science, PM-Bench evaluates how well LLM agents maintain user intentions, execute delayed intentions, and monitor latent environment changes. Over the course of a simulated seven-day week, agents must continue an ongoing activity while deciding whether any deferred task is due. We compare eight state-of-the-art LLMs on PM-Bench under eight different agent configurations. PM-Bench proves challenging across all settings: the best method, a GPT-5.4 agent, reaches only 65.1\% F1 score under our evaluation. Furthermore, no single strategy for improving prospective memory dominates across models. We release PM-Bench as a controlled testbed for diagnosing these failures and developing training or inference-time interventions that support reliable prospective behavior.

代理人工智能面临的一个重大挑战是前瞻性记忆:在其他活动进行的同时,在特定的未来提示或状态下执行意图的能力。我们介绍了PM-Bench,这是一个基于文本的基准,用于测量现代大型语言模型(LLM)代理的前瞻性记忆能力。PM-Bench受到认知科学中虚拟周(Virtual Week)范式的启发,评估LLM代理在多大程度上保持用户意图、执行延迟意图以及监测潜在环境变化。在模拟的七天周中,代理必须在继续进行一项活动的同时,决定是否有任何延迟任务到期。我们在八种不同的代理配置下比较了八种最先进的LLM在PM-Bench上的表现。PM-Bench在所有设置中都证明了其挑战性:最佳方法,即GPT-5.4代理,在我们的评估中仅达到65.1%的F1得分。此外,没有任何单一策略在各模型中主导于改善前瞻性记忆。我们发布PM-Bench作为一个受控测试平台,以诊断这些失败并开发支持可靠前瞻性行为的训练或推理时干预措施。

Critic Experience Bank: Self-Evolving Step-Level Confidence Estimation for LLM Agents
评论者经验库:自我演化的逐步置信度估计用于大型语言模型代理
Abstract
LLM agents act in external environments where each action changes the state that later decisions condition on, and where a single wrong step can waste interaction budget or trigger irreversible side effects long before the final failure is observed. Reliable deployment therefore requires \emph{step-level confidence estimation}: a calibrated probability that each proposed action is productive, available \emph{before} the action is executed. Existing LLM confidence estimators are designed to score a response from the given prompt, but agent confidence also depends on execution consequences: whether similar actions in similar situations actually advanced the task after the environment responded. We introduce the \method (\methodshort), a self-evolving critic framework in which an LLM critic accumulates evidence from its own past judgments and their observed consequences. After each trajectory, a hindsight LLM that sees the full execution feedback votes on whether each step was productive. The resulting pseudo-labels populate a memory bank from which related productive and unproductive experiences are retrieved into the critic's prompt whenever a similar step recurs. \methodshort requires no training and uses no ground truth step labels. Across three agent benchmarks and three critic backbones, \methodshort attains the best calibration (ECE and Brier) and ranking (AUC) in every dataset--critic combination, reducing ECE by up to $54\%$ relative to the strongest training-free baseline.

大型语言模型(LLM)代理在外部环境中执行操作,每个操作都会改变后续决策所依赖的状态,而单个错误的步骤可能会浪费交互预算或在最终失败被观察到之前触发不可逆的副作用。因此,可靠的部署需要 extit{逐步置信度估计}:在执行操作之前,校准每个提议操作是有效的概率。现有的LLM置信度估计器旨在对给定提示的响应进行评分,但代理的置信度还依赖于执行结果:在环境响应后,类似情况下的类似操作是否确实推动了任务的进展。我们引入了 extit{Critic Experience Bank}( extit{CEB}),这是一个自我演化的评论者框架,其中LLM评论者从其过去的判断及其观察到的结果中积累证据。在每个轨迹之后,一个能够看到完整执行反馈的后见LLM对每个步骤是否有效进行投票。生成的伪标签填充了一个记忆库,当类似步骤再次出现时,相关的有效和无效经验会被检索到评论者的提示中。 extit{CEB}不需要训练,也不使用真实的步骤标签。在三个代理基准和三个评论者基础上, extit{CEB}在每个数据集-评论者组合中都达到了最佳的校准(ECE和Brier)和排名(AUC),相较于最强的无训练基线,ECE降低了多达54%。

Isolation as a First-Class Principle for LLM-Agent System Safety: Concepts, Taxonomy, Challenges and Future Directions
将隔离作为大型语言模型代理系统安全的首要原则:概念、分类、挑战与未来方向
Abstract
The capability of LLM agents to function as the ``brain'' of a system fundamentally expands the scope of analysis beyond a standalone model. Consequently, safety is no longer only about input--output content alignment. It also concerns system behavior and real-world execution outcomes. However, the current literature is fragmented across attack types, applications, and benchmarks. This makes it hard to explain why failures such as prompt injection, tool misuse, and memory poisoning often share the same structural cause, and how they spread through an agent workflow. In this survey, we treat isolation as a first-class principle for LLM-agent system safety. By isolation, we refer to the separation of user inputs, tool access, execution channels, inter-agent communication, and environment-originated context. We organize the literature with a boundary-centric taxonomy of five boundaries: user-agent, agent-tool, agent-execution, agent-agent, and system-environment. This view helps identify where the loss of isolation first occurs, how compromise propagates across boundaries, and which defenses are most relevant at each interface. We also summarize cross-boundary failure paths, discuss open challenges, and outline a research agenda for isolation-by-construction in future agent systems.

大型语言模型(LLM)代理作为系统“脑”的能力,根本上扩展了分析的范围,超越了单一模型。因此,安全性不再仅仅关乎输入与输出内容的一致性,还涉及系统行为和现实世界执行结果。然而,现有文献在攻击类型、应用和基准测试方面存在碎片化。这使得很难解释为何诸如提示注入、工具误用和内存中毒等失败通常共享相同的结构性原因,以及它们如何在代理工作流中传播。在本次调研中,我们将隔离视为LLM代理系统安全的首要原则。我们所指的隔离是指用户输入、工具访问、执行通道、代理间通信以及环境来源上下文的分离。我们以边界为中心的五个边界分类组织文献:用户-代理、代理-工具、代理-执行、代理-代理和系统-环境。这种视角有助于识别隔离首次丧失的地方、妥协如何在边界间传播,以及在每个接口上哪些防御措施最为相关。我们还总结了跨边界失败路径,讨论了开放挑战,并为未来代理系统中的构建隔离研究制定了研究议程。

Accepted Prefixes Are Not All You Need: A Negative Result on PEFT-Based Block-Diffusion Drafting
接受的前缀并不是你所需要的一切:关于基于PEFT的块扩散草拟的负面结果
Abstract
Speculative decoding accelerates autoregressive language model inference by using a cheap drafter to propose multiple future tokens and a target model to verify them. A common design goal is therefore to improve draft quality while reducing auxiliary parameters and systems overhead. We study a negative result for this direction through PEFT-BD, a same-backbone speculative decoding method in which a LoRA-like adapter acts as a block-diffusion drafter for an autoregressive verifier. PEFT-BD is motivated by several attractive properties: it avoids tokenizer mismatch, avoids loading a separate draft model, adds only a small number of trainable parameters, and uses a BD3LM-style denoising objective to propose a block of tokens in parallel. Despite these advantages, PEFT-BD does not yield a practical speedup in our Qwen3-0.6B experiments. Although the method obtains nontrivial accepted prefixes, profiling shows that each speculative step requires an adapter-enabled full-backbone draft pass followed by an adapter-disabled full-backbone verification pass. Thus, the drafter is parameter-efficient but not compute-efficient. Our results isolate a simple but important condition for successful speculative decoding: the drafter must be substantially cheaper to execute than the verifier. Longer accepted prefixes alone cannot compensate when draft computation remains verifier-scale.

推测解码通过使用廉价的草拟器提出多个未来标记并使用目标模型进行验证,从而加速自回归语言模型的推理。因此,一个常见的设计目标是提高草拟质量,同时减少辅助参数和系统开销。我们通过PEFT-BD研究了这一方向的负面结果,PEFT-BD是一种相同骨干的推测解码方法,其中一个类似LoRA的适配器充当自回归验证器的块扩散草拟器。PEFT-BD的动机源于几个吸引人的特性:它避免了分词器不匹配,避免加载单独的草拟模型,仅增加少量可训练参数,并使用BD3LM风格的去噪目标并行提出一组标记。尽管具有这些优势,在我们的Qwen3-0.6B实验中,PEFT-BD并未带来实质性的加速。尽管该方法获得了非平凡的接受前缀,但分析显示每个推测步骤都需要一个启用适配器的完整骨干草拟过程,随后是一个禁用适配器的完整骨干验证过程。因此,草拟器在参数上是高效的,但在计算上并不高效。我们的结果隔离了成功推测解码的一个简单但重要的条件:草拟器的执行成本必须显著低于验证器。当草拟计算仍然保持在验证器规模时,单靠较长的接受前缀无法弥补。

EVOQUANT: Self-Evolving Verifier-Guided Strategy Optimization for Robust Quantitative Trading
EVOQUANT:自我演化的验证者引导策略优化框架用于稳健的量化交易
Abstract
Quantitative strategy optimization remains largely manual, requiring domain experts to identify weak signals, tune risk-control rules, and repeatedly validate iterative revisions. Large language models can accelerate this process, but directly relying on them to rewrite trading strategies often introduces hallucinated edits, strategy drift, and backtest overfitting. We propose EVOQUANT, a self-Evolving Verifier-guided framework for strategy Optimization in Quantitative trading. Our method utilizes LLMs to deeply diagnose performance bottlenecks, generates semantically controlled candidate edits, selects the best strategy through a multi-stage verification pipeline, and distills optimization experience into reusable knowledge for continual self-improvement. We evaluate our method using seven representative strategies: four from the A-share market and three from the Crypto market. Experimental results show that our method significantly improves the Sharpe ratio across all tested strategies: the average test Sharpe increases from -0.298 to 0.538, and the best-performing strategy achieves a 199% relative improvement. Ablation studies and stress tests under stricter conditions further validate the effectiveness and robustness of the framework. Overall, this work transforms quantitative strategy optimization from costly manual trial and error into an automated and verifiable iterative paradigm, offering a new path for applying large language models to financial strategy research.

量化策略优化在很大程度上仍然是手动进行的,要求领域专家识别弱信号、调整风险控制规则,并反复验证迭代修订。大型语言模型可以加速这一过程,但直接依赖它们重写交易策略往往会引入虚假编辑、策略漂移和回测过拟合。我们提出了EVOQUANT,一个自我演化的验证者引导框架,用于量化交易中的策略优化。我们的方法利用大型语言模型(LLMs)深入诊断性能瓶颈,生成语义控制的候选编辑,通过多阶段验证流程选择最佳策略,并将优化经验提炼为可重用的知识,以实现持续自我改进。我们使用七个具有代表性的策略评估我们的方法:四个来自A股市场,三个来自加密市场。实验结果表明,我们的方法显著提高了所有测试策略的夏普比率:平均测试夏普从-0.298提高到0.538,表现最佳的策略实现了199%的相对提升。消融研究和在更严格条件下的压力测试进一步验证了该框架的有效性和稳健性。总体而言,这项工作将量化策略优化从高成本的手动试错转变为一种自动化和可验证的迭代范式,为将大型语言模型应用于金融策略研究提供了一条新路径。

Do We Really Need Transformers for Global Spatial Information Extraction in Traffic Forecasting?
我们真的需要变压器来进行交通预测中的全球空间信息提取吗?
Abstract
Existing traffic forecasting models commonly focus on extracting spatial dependencies, particularly global spatial information, which characterizes the representations obtained through interactions between each individual node and all nodes across the traffic network. However, the underlying mechanism by which such global information is modeled and extracted remains insufficiently investigated. Whether global information must be extracted by high-degree-of-freedom adaptive attention or can be captured by a simple global aggregation operator remains unclear. For this purpose, we design a controlled ablation framework that replaces only the spatial mixing module to test attention-based global interaction. Across six traffic benchmarks, uniform full-range mixing and standard spatial attention each achieve lower MAE on three datasets, with only a 0.14% difference in mean MAE, while the former reduces node-scale spatial mixing complexity from O(N2) to O(N). Mechanism analysis further decomposes spatial attention into a row-uniform global background and a non-uniform residual. The residual shows dataset-dependent marginal value, suggesting that spatial attention should be justified by stable gains beyond a row-uniform global background. The corresponding source code is publicly available at: https://github.com/uuesti/U-Trans

现有的交通预测模型通常侧重于提取空间依赖关系,特别是全球空间信息,这种信息通过交通网络中每个节点与所有节点之间的交互来表征。然而,如何建模和提取这种全球信息的基本机制仍然未得到充分研究。全球信息是否必须通过高自由度的自适应注意力来提取,或者可以通过简单的全球聚合算子来捕获,仍然不明确。为此,我们设计了一个受控消融框架,仅替换空间混合模块以测试基于注意力的全球交互。在六个交通基准测试中,均匀全范围混合和标准空间注意力在三个数据集上均实现了较低的平均绝对误差(MAE),两者之间的平均MAE仅相差0.14%,而前者将节点规模的空间混合复杂度从O(N²)降低到O(N)。机制分析进一步将空间注意力分解为行均匀的全球背景和非均匀的残差。残差显示出依赖于数据集的边际价值,表明空间注意力应通过超出行均匀全球背景的稳定收益来证明其合理性。相应的源代码可在以下网址公开获取:https://github.com/uuesti/U-Trans

Function-Aware Fill-in-the-Middle as Mid-Training for Coding Agent Foundation Models
功能感知的中间填充作为编码代理基础模型的中期训练
Abstract
Coding agents must integrate external tool returns into ongoing reasoning - a capability that standard left-to-right pretraining on code exposes only in its forward direction. We observe that the action-observation-continuation loop of a coding agent is structurally isomorphic to a function call site, where a caller binds arguments, a callee returns a value computed elsewhere, and downstream code consumes that value. This conditioning structure exists at internet scale in ordinary code. We exploit it through function-aware fill-in-the-middle (FIM) mid-training: a self-supervised objective that masks functions selected via program dependency graph analysis and a complexity-inferability double criterion. We mid-train Qwen2.5-Coder-Instruct (7B/14B) and Qwen3-8B on a 2.6B-token decontaminated corpus drawn from 968 GitHub repositories, then apply existing agentic post-training pipelines. Mid-training improves SWE-Bench-Verified by +2.8/+3.0 at 7B/14B and by +3.2 on Qwen3-8B; SWE-Bench-Lite gains are +3.7/+4.0/+5.4 on the same models. The improvement holds across two post-training pipelines (R2E-Gym, SWE-Smith) and on a non-Qwen2.5 base (Qwen3-8B with SWE-Lego). Beyond in-domain gains, mid-training also mitigates the capability erosion that agentic post-training otherwise inflicts on non-agent coding (e.g., LiveCodeBench) and non-coding tool-use benchmarks (tau-bench, BFCL): although the mid-training corpus contains Python code only, the function-call inductive bias survives post-training and yields consistent gains.

From Observation to Insight: Mechanistic World Models and the Quest for Autonomous Discovery
从观察到洞察:机制世界模型与自主发现的探索
Abstract
Recent advances in foundation models have transformed AI for Science, enabling remarkably accurate predictive performance across domains ranging from protein folding to weather forecasting. Yet prediction alone does not constitute scientific discovery. Scientific understanding depends on uncovering the reusable explanatory mechanisms that generate observations, whereas contemporary machine learning remains fundamentally organised around predictive mappings rather than explanatory structure. In this paper, we argue that scientific discovery is fundamentally a problem of knowledge organisation. To this end, we introduce Mechanistic World Models, a new design paradigm that places reusable mechanisms at the centre of representation, computation and learning. Drawing on insights from the philosophy of science, we derive the computational capabilities required for discovery, identify the design principles and inductive pressures that encourage explanatory knowledge to emerge, and formalise the anatomy of a mechanism-centric world model. Finally, we show how diverse research directions including mechanistic interpretability, causal representation learning, equation discovery and modular architectures capture complementary ingredients of this paradigm while lacking a unified framework. We propose Mechanistic World Models as a conceptual foundation and computational blueprint for moving AI beyond predictive forecasting towards autonomous scientific discovery.

近期基础模型的进展已经改变了科学领域的人工智能,使其在从蛋白质折叠到天气预报等多个领域实现了显著准确的预测性能。然而,仅仅依靠预测并不能构成科学发现。科学理解依赖于揭示生成观察结果的可重用解释机制,而当代机器学习仍然基本围绕预测映射而非解释结构进行组织。本文论证,科学发现根本上是一个知识组织的问题。为此,我们引入机制世界模型(Mechanistic World Models),这一新的设计范式将可重用机制置于表示、计算和学习的中心。基于科学哲学的见解,我们推导出发现所需的计算能力,识别出鼓励解释性知识涌现的设计原则和归纳压力,并形式化机制中心世界模型的结构。最后,我们展示了包括机制可解释性、因果表示学习、方程发现和模块化架构在内的多样化研究方向如何捕捉这一范式的互补成分,同时缺乏统一的框架。我们提出机制世界模型作为一个概念基础和计算蓝图,以推动人工智能从预测性预报向自主科学发现迈进。

TRACE: An Operational Reasoning Schema for Auditable Agentic Commitments
TRACE:可审计代理承诺的操作推理模式
Abstract
This paper defines TRACE (Typed Reasoning And Commitment Evidence): a typed, versioned schema for recording reasoning traces, a reference procedure for writing records against it, and one operating discipline, no durable state change without a record. The paper argues in three layers that reasoning is not in the language model: the autoregressive mechanism natively computes association; chain-of-thought and reinforcement learning inherit its limits; and the formal constructs of reasoning theory, from Socratic procedure to Pearl's ladder, are absent as machinery. The schema answers the absence with fields and tests: the TraceRecord and its causal specialization, an eight-stage reference writer, a gate-first measurement regime, the TRACE-Bench protocol, and the consumers, memory admission, plan gating, temporal regret, and verdict reuse, whose more auditable decisions are the measure of the record. A record-consumer contract states what a record guarantees and what a consumer must honor in return, making the schema an operational interface rather than a passive document. Two worked examples run in the main text: a music-lessons argument traced from sentence to typed verdict, separating association, intervention, and prescription; and a flood search-and-rescue vignette in which a predictive world model reports confident plan success that its own support and out-of-distribution scores contradict, so the record defers the commitment, requests a bounded observation, revises append-only, and clears a different branch. The vignette is illustrative, not empirical; closed-loop evaluation is left to future work, so the contribution is the schema and its contract, not a performance claim. Appendices carry the full schema, writer algorithms and cost model, clinical and policy illustrations, the benchmark protocol, convergence metrics, and usage scenarios.

The Model Knows Your Project, Not You: Measuring Recognition in LLMs with NameRank
模型了解你的项目,而不是你:使用 NameRank 测量大语言模型的识别能力
Abstract
What a frontier model recalls about a person or tool from its own weights -- before any retrieval step -- often shapes the first description a human sees, making that parametric corpus presence a measurement problem. Citations explain about a third of whether a model recognizes a researcher; we target the residual and build NameRank, a [0,1] recognition score: each of 4,685 entities in 54 cohorts is probed with one open-ended question across 36 models, and an independent judge returns a binary verdict against a curated gold -- did the model state a specific, non-guessable fact about this exact entity? -- so hallucination, context echo, and guesses earn nothing. Synthetic-null entities hold the floor near zero, and verdicts track the entity, not the model. One thesis organizes the findings: recognition is paid to named, indexable artifacts, not to credentials or titles. Every Olympic-style credential sits below a working-researcher baseline, because no named artifact ships with the medal, yet the ranking inverts at the marquee tier, where Nobel, Turing, and Fields laureates saturate the panel. For independent creators the tool out-ranks its maker, and the credential that does propagate is a named method or awarded paper. Being one of many named contributors to a celebrated artifact, by contrast, earns almost nothing -- the authors listed on a flagship model report or system card sit near the recognition floor -- because recognition attaches to the artifact's own distinctive name, not to the roster behind it. No bibliometric predicts recognition well; top-density institutions out-recognize peers at matched citations; and on 258 news events recognition loads on peak salience, not persistence. A self-report probe shows introspection reads a corpus prior, not its own knowledge.

Abstract
Musculoskeletal diseases are among the leading causes of disability worldwide and create the greatest global need for rehabilitation. Because recovery, remodelling and degeneration often unfold over months to years, musculoskeletal care requires longitudinal management that repeatedly integrates evolving patient evidence, external medical knowledge and stage-specific functional goals. In routine practice, this evidence is fragmented across visits, departments and hospital systems, limiting individualized, evidence-based care. Here we report OrthoPilot, a clinical artificial intelligence system powered by a large language model that integrates hospital data streams with authoritative external knowledge for continuous musculoskeletal management. OrthoPilot autonomously retrieves real-time imaging, laboratory, pathology and order data and converts evolving patient states into evidence-based decisions from admission diagnosis to rehabilitation planning. We established a specialist-validated benchmark from real-world electronic health records spanning 1,000 disease codes. In a reader study across the complete care pathway, OrthoPilot was compared with 81 orthopaedic physicians and surpassed experts with 25 years of experience in diagnostic reasoning, clinical decision-making and management planning. It also outperformed all evaluated intelligent systems across 60 external clinical centres. In a prospective study of 1,870 complex cases, OrthoPilot increased full-chain management success by 10.6%. During an 8-month randomised deployment involving 8,240 inpatients, it increased cumulative cases per bed by 9.7% and improved patient-reported access to health information. These results move clinical AI from predicting isolated events toward executing longitudinal management across complete musculoskeletal care pathways.

Vertical Standardisation for High-Risk AI Systems under the EU AI Act: A Domain-Specific Framework for Algorithmic Hiring
欧盟人工智能法下高风险人工智能系统的垂直标准化:针对算法招聘的领域特定框架
Abstract
According to the recent European legislation, high-risk AI systems will have to adapt in order to comply with requirements related to specific areas, like risk management, data quality and governance, logging and traceability, technical documentation, transparency, human oversight, and accuracy, as outlined in the European Artificial Intelligence (AI) Act. As the standardisation process for AI is expected to remain iterative and, so far, there are no European standards on AI fully covering the challenges of algorithmic hiring, we propose specific standardisation-oriented recommendations related to the relevant AI areas specified by the European Commission. For each of these areas, we set the context by describing the requirements that AI systems in high-risk domains, and especially in recruitment, should fulfil, as well as the activities that should be carried out to ensure their appropriate use and desired performance, in line with the requirements deriving from the AI Act. Unlike existing horizontal approaches to AI governance and standardisation, this paper contributes a vertical, domain-specific framework for algorithmic hiring, and especially ranking-based recruitment systems, by mapping the requirements of the AI Act to concrete standardisation recommendations, focusing on lifecycle discrimination risks, fairness-aware data governance, explainability, human oversight, and post-deployment monitoring in recruitment systems. Even though our recommendations were informed by the outcomes of the European project FINDHR, they are not tied to the project's technical artefacts and could be implemented using alternative methods, tools, or governance mechanisms.

Agentic Service-Oriented Computing: A Manifesto for the Next Frontier of Service-Oriented Computing
代理服务导向计算:服务导向计算下一个前沿的宣言
Abstract
The rapid emergence of LLM-powered autonomous and semi-autonomous agents is reshaping software systems from static, request-response components into goal-directed, adaptive, and tool-using computational actors. As these agents move from isolated cognitive prototypes into complex distributed workflows, they confront challenges that the Service-Oriented Computing community has studied for more than two decades: composition, interoperability, quality of service, lifecycle management, governance, security, and trust. Yet much of today's agentic AI ecosystem is developing these foundations ad hoc, without the engineering rigour required for dependable enterprise and societal deployment. This paper introduces Agentic Service-Oriented Computing (ASOC) as a new research and practice area concerned with engineering agents as services, orchestrating services through autonomous and semi-autonomous agents, and governing ecosystems of agents and services under constraints of trust, cybersecurity, compliance, performance, and accountability. We articulate six foundational principles of ASOC (harness-ability, composability, lifecycle engineering, trustworthiness by design, goal-driven orchestration, and observability/accountability) and organise a five-dimensional research agenda spanning: (i) agentic services foundations and lifecycle engineering; (ii) composition, orchestration, and interoperability; (iii) governance, observability, and accountability; (iv) security, trust, and risk management; and (v) evaluation, certification, and Agentic QoS. We argue that the Services Computing community is especially well positioned to provide the conceptual and engineering spine for this emerging field, transforming agentic AI from fragmented demonstrations into dependable, service-based systems worthy of human and organisational trust.

大型语言模型(LLM)驱动的自主和半自主代理的快速出现正在将软件系统从静态的请求-响应组件转变为目标导向的、自适应的、使用工具的计算行为者。当这些代理从孤立的认知原型转向复杂的分布式工作流时,它们面临着服务导向计算社区研究了超过二十年的挑战:组合性、互操作性、服务质量、生命周期管理、治理、安全性和信任。然而,今天的代理人工智能生态系统在很大程度上是临时开发这些基础,没有为可靠的企业和社会部署所需的工程严谨性。本文介绍了代理服务导向计算(Agentic Service-Oriented Computing,ASOC)作为一个新的研究和实践领域,关注于将代理作为服务进行工程设计,通过自主和半自主代理编排服务,以及在信任、网络安全、合规性、性能和问责制的约束下治理代理和服务的生态系统。我们阐明了ASOC的六个基础原则(可利用性、可组合性、生命周期工程、设计中的可信性、目标驱动的编排和可观察性/问责制),并组织了一个跨越五个维度的研究议程: (i) 代理服务的基础和生命周期工程; (ii) 组合、编排和互操作性; (iii) 治理、可观察性和问责制; (iv) 安全、信任和风险管理; (v) 评估、认证和代理服务质量(Agentic QoS)。我们认为,服务计算社区特别适合为这一新兴领域提供概念和工程支撑,将代理人工智能从零散的演示转变为值得人类和组织信任的可靠服务型系统。

Atomic Units of X: The Compression Layer of Intelligence
X的原子单位:智能的压缩层
Abstract
This paper proposes a theoretical framework for understanding intelligence as a process of atomic compression and compositional reuse. We argue that cognitive, biological, computational, and organizational systems achieve scalable intelligence by decomposing complex phenomena into reusable atomic units that can be recombined into higher-order structures. Drawing on evidence from cognitive science, information theory, evolutionary biology, software engineering, medicine, legal reasoning, education, music, and artificial intelligence, the paper develops the concept of atomic units as fundamental compression layers that support efficiency, transfer, interpretability, and evolvability. The central contribution is the Compression Calculus, a formal framework for comparing surface-level representations with atomic representations and for describing how compression gains compound across abstraction layers. We introduce the Compounding Cascade thesis, according to which each additional layer of abstraction multiplicatively increases representational efficiency rather than merely adding incremental savings. The paper further argues that contemporary AI systems often operate at suboptimal levels of representation, relying on token-level processing or document-level retrieval rather than stable, concept-level atomic structures. In this view, large language models are best understood not as complete knowledge architectures, but as dynamic fusion engines capable of navigating, sequencing, and recombining atomic units. The framework provides a foundation for designing self-evolving knowledge systems that can discover, refine, and compose new primitives over time. By reframing intelligence as compression through compositional abstraction, the paper offers a unifying perspective on expertise, knowledge representation, explainable AI, and the future architecture of adaptive intelligent systems.

A Learning-Rate-Gated Failure of GRPO in a Small Language and Vision-Language Model Web Agent: A Controlled Null and Its Mechanism
小型语言和视觉-语言模型网络代理中GRPO的学习率门控失效:一个受控的无效及其机制
Abstract
Reinforcement learning with verifiable rewards, and Group Relative Policy Optimization (GRPO) in particular, is now run routinely on a supervised checkpoint in the hope of producing a stronger agent. We ask whether it adds skill to a small language and vision-language model web agent at the 4B to 8B scale, or whether it mostly reshapes behavior the supervised model already has. Across a control grid of 18 runs that varies learning rate, KL weight, seed, initialization, and clipping, no configuration credibly improves the success rate of a strong supervised baseline on tasks the agent has largely mastered. On the text track, moderate to high learning rates make it credibly worse. The null holds under paired testing, 25 evaluation seeds, 6 training seeds, changes to the recipe, both text and Set-of-Marks screenshot observations, and scaling the backbone to 8B; the credible harm is a text-track finding and is only nominal under Set-of-Marks. To show that the null reflects the setting and not a broken pipeline, we run the identical harness, reward, and recipe on tasks whose reward is reachable by sampling, and there the success rate rises by 22 points with a paired interval that excludes zero. GRPO therefore helps only when there is headroom to climb, meaning the sampled policy already succeeds more often than the greedy one. We then explain the failure. A middle learning rate degrades the agent and a high one collapses it, and the two regimes form a double dissociation: grafting localizes the degrade regime to the attention and MLP blocks, while the collapse regime cannot be traced to any single group, and the embedding change that dominates the weight movement is causally inert. At 4B, effective rank in the late layers tracks capability in both directions; at 8B the two come apart. This coupling is specific to the smaller model, so we report it as scale-dependent.

MaxSAT-Based Feedback for Guiding Vision-Language Models in Sudoku
基于MaxSAT的反馈指导视觉-语言模型在数独中的应用
Abstract
Vision--Language Models (VLMs) have recently demonstrated promising performance on structured visual reasoning tasks, including grid-based puzzles. However, despite strong perceptual capabilities, these models lack explicit mechanisms for enforcing logical consistency and frequently generate assignments that violate underlying constraints. In this paper, we propose a neuro-symbolic approach that integrates formal constraint reasoning into the VLM solving process via a Maximum Satisfiability (MaxSAT) oracle. Rather than computing solutions directly, the symbolic component acts as a consistency validator and refinement engine. Candidate placements generated by the VLM are encoded as soft clauses in a partial MaxSAT formulation, while Sudoku constraints remain hard clauses. When inconsistencies arise, the MaxSAT solver identifies a largest mutually consistent subset of assignments, which is then translated into structured textual and visual feedback to guide subsequent refinements. We evaluate our approach on a Sudoku dataset across multiple open-source and closed-access VLMs. Results show that MaxSAT-based feedback improves logical consistency and increases the number of solved instances, particularly in full-board refinement mode. These findings demonstrate that symbolic optimisation can enhance the reliability of vision-language reasoning.

视觉-语言模型(VLMs)最近在结构化视觉推理任务中表现出良好的性能,包括基于网格的谜题。然而,尽管这些模型具有强大的感知能力,但它们缺乏强制逻辑一致性的明确机制,常常生成违反基本约束的分配。在本文中,我们提出了一种神经符号方法,通过最大可满足性(MaxSAT)oracle将形式约束推理集成到VLM求解过程中。该符号组件并非直接计算解决方案,而是充当一致性验证器和精炼引擎。VLM生成的候选放置被编码为部分MaxSAT公式中的软子句,而数独约束则保持为硬子句。当出现不一致时,MaxSAT求解器识别出一个最大的相互一致的分配子集,然后将其转换为结构化的文本和视觉反馈,以指导后续的精炼。我们在多个开源和闭源的VLM上评估了我们的方法,使用了一个数独数据集。结果表明,基于MaxSAT的反馈提高了逻辑一致性,并增加了解决实例的数量,特别是在全盘精炼模式下。这些发现表明,符号优化可以增强视觉-语言推理的可靠性。

LLMs Can See the Smoke but not the Fire: Evaluating Abductive Reasoning with Elenchos
大型语言模型能够看到烟雾却看不到火焰:使用Elenchos评估溯因推理
Abstract
Large language models (LLMs) excel at pattern recognition and text generation, but their capacity for abductive inference - inferring latent hypotheses that explain observed behavior - remains poorly understood. Here, we introduce Elenchos (named after the Socratic method of cross-examination), a generative evaluation framework that measures abductive reasoning as a structural inverse problem. Given a reference formal system, such as the lambda-calculus, and a potentially mutated counterpart, agents must determine whether a mutation has occurred and infer the rule modifications responsible for the resulting behavioral differences. Evaluating frontier and mid-tier LLMs reveals a consistent detection-attribution dissociation: models often recognize that a system has been altered but struggle to identify the latent mutations causing the observed discrepancies. Performance degrades substantially under interacting mutations, where models frequently recover only a subset of the underlying mutations. Preliminary evidence also suggests diminishing returns from increased inference-time reasoning, with only modest improvements under larger reasoning budgets, though this finding requires further validation.

大型语言模型(LLMs)在模式识别和文本生成方面表现出色,但它们在溯因推理方面的能力——推断解释观察到的行为的潜在假设——仍然不够清楚。在此,我们介绍Elenchos(以苏格拉底的交叉审问法命名),这是一个生成性评估框架,用于将溯因推理视为一种结构性逆问题。在给定一个参考形式系统(如λ演算)和一个可能变异的对应系统的情况下,智能体必须判断是否发生了变异,并推断导致行为差异的规则修改。对前沿和中层LLMs的评估揭示了一种一致的检测-归因分离现象:模型通常能够识别出系统已被更改,但在识别导致观察到的差异的潜在变异方面却存在困难。在相互作用的变异下,模型的表现显著下降,通常只能恢复潜在变异的一个子集。初步证据还表明,推理时间的增加带来的收益递减,只有在更大的推理预算下才有适度的改善,尽管这一发现需要进一步验证。

Tracing Agentic Failure from the Flow of Success
从成功的流动中追踪能动性失败
Abstract
Failure attribution for LLM-based agentic systems, i.e., identifying which steps in a failure trajectory caused the task to fail, is critical for debugging and improving these systems. Existing approaches either rely on prompting-based pipelines, which are computationally expensive, or require post-training on failure trajectories with step-level error annotations, which are costly to collect and difficult to scale. We argue that a practical failure attribution model should be lightweight and trainable without step-level supervision on failure data. To this end, we address unsupervised failure attribution, i.e., training exclusively on successful trajectories and identifying error steps at inference time given a failure trajectory. We propose OAT, which casts this problem as one-class learning with neural controlled differential equations, modeling the dynamical pattern of successful trajectories in latent space. At inference time, each step in a failure trajectory is assigned an anomaly score based on its deviation from the dynamics learned on successful trajectories, which is then used to form a set of error steps. With training on only 100 successful trajectories, experiments show that OAT is 200--5000 $\times$ faster than prompting-based baselines, and, at the same time, consistently outperforms them in both in-domain and out-of-distribution datasets with +20% and +7% F1 scores, respectively, demonstrating that OAT is a promising and efficient direction for diagnosing agentic system failures.

对于基于大型语言模型(LLM)的能动系统,失败归因,即识别在失败轨迹中哪些步骤导致了任务失败,对于调试和改进这些系统至关重要。现有的方法要么依赖于基于提示的管道,这在计算上成本高昂,要么需要在失败轨迹上进行后训练,并附有逐步错误注释,这在收集上成本高且难以扩展。我们认为,一个实用的失败归因模型应该是轻量级的,并且无需在失败数据上进行逐步监督进行训练。为此,我们提出无监督失败归因,即仅在成功轨迹上进行训练,并在推理时根据给定的失败轨迹识别错误步骤。我们提出了OAT,将此问题视为一种单类学习,利用神经控制微分方程建模成功轨迹在潜在空间中的动态模式。在推理时,失败轨迹中的每一步都根据其与成功轨迹上学习到的动态的偏差被分配一个异常分数,然后用于形成一组错误步骤。在仅对100条成功轨迹进行训练的情况下,实验表明OAT的速度比基于提示的基线快200到5000倍,同时在领域内和分布外数据集上均表现出色,F1分数分别提高了20%和7%,这表明OAT是诊断能动系统失败的一个有前景且高效的方向。

Accuracy and Normalized Accuracy under Length Bias: Analysis, Guidelines, and a Bayesian Alternative
长度偏差下的准确性与归一化准确性:分析、指南及贝叶斯替代方案
Abstract
Multiple-choice benchmarks that rank candidate completions by conditional log-probability suffer from a length bias: because log-probabilities sum over tokens, longer answers tend to be penalized relative to shorter ones in practice. A common mitigation is to normalize scores by completion length, but we show empirically that this heuristic frequently over-corrects, introducing a bias toward longer answers instead. We first analyze these scoring rules, characterizing when standard and length-normalized accuracy are appropriate and how their length biases depend on the distribution of completion lengths. Motivated by this analysis, we introduce \emph{Bayesian accuracy}, a scoring rule that computes the posterior probability of each candidate under an explicit prior over answer length, thereby removing linear length effects. Bayesian accuracy is a drop-in replacement for likelihood-based multiple-choice evaluation, requires no additional forward passes, and consistently exhibits lower empirical length bias than both standard and length-normalized accuracy across benchmarks and few-shot settings.

Do We Really Need Multimodal Emotion Language Models Larger Than 1B Parameters?
我们真的需要超过10亿参数的多模态情感语言模型吗?
Abstract
Recent advances in multimodal large language models (MLLMs) have significantly improved the performance of multimodal emotion recognition (MER) and enabled interpretable description generation by jointly modeling video, audio, and language, etc. However, these performance improvements are often accompanied by an increase in model parameter size (e.g, at least 7B), which simultaneously incurs high computational costs and reduces inference efficiency, thereby hindering real-time deployment on resource-constrained platforms such as robots and mobile devices. This raises a fundamental question: do we really need the multimodal MER model larger than 1B parameters for high-quality MER? In this paper, we challenge the assumption that larger models are inherently necessary and proposes a lightweight MER framework (called Light-MER), which achieves better and faster multimodal sentiment understanding and recognition through knowledge distillation. It can transfer knowledge from a strong, large-scale teacher model to a lightweight sub-billion-parameter student model, aiming to preserve rich multimodal emotion reasoning and recognition while substantially improving deployment efficiency. Specifically, we introduce two new optimization strategies to enhance knowledge transfer: (1) a new optimal transport loss that combines Sliced Wasserstein Distance with hidden-state alignment, and (2) a new multi-reward optimization strategy based on GRPO that balances MER performance and efficiency, aimed at further enhancing the learning capabilities of student models. Extensive experiments on nine benchmark datasets demonstrate that Light-MER achieves state-of-the-art performance while significantly improving inference efficiency. This highlights the strong potential of small multimodal emotion language models for future research. Code is available at https://github.com/GAIR-Lab/Light-MER.

近年来,多模态大型语言模型(MLLMs)的进展显著提升了多模态情感识别(MER)的性能,并通过联合建模视频、音频和语言等实现了解释性描述生成。然而,这些性能提升往往伴随着模型参数规模的增加(例如,至少为70亿),这同时带来了高计算成本并降低了推理效率,从而阻碍了在资源受限的平台(如机器人和移动设备)上的实时部署。这引发了一个根本性的问题:我们真的需要超过10亿参数的多模态MER模型来实现高质量的MER吗?在本文中,我们质疑了更大模型固有必要性的假设,并提出了一种轻量级的MER框架(称为Light-MER),该框架通过知识蒸馏实现了更好且更快的多模态情感理解与识别。它能够将知识从强大且大规模的教师模型转移到轻量级的子亿参数学生模型,旨在保留丰富的多模态情感推理与识别,同时显著提高部署效率。具体而言,我们引入了两种新的优化策略以增强知识转移:(1)一种新的最优传输损失,结合了切片Wasserstein距离与隐藏状态对齐;(2)一种基于GRPO的新多奖励优化策略,平衡MER性能与效率,旨在进一步增强学生模型的学习能力。在九个基准数据集上的广泛实验表明,Light-MER实现了最先进的性能,同时显著提高了推理效率。这突显了小型多模态情感语言模型在未来研究中的巨大潜力。代码可在 https://github.com/GAIR-Lab/Light-MER 获取。

Who Grades the Grader? Co-Evolving Evaluation Metrics and Skills for Self-Improving LLM Agents
谁来评估评估者?自我改进大语言模型代理的共同演化评估指标与技能
Abstract
Self-evolving agent systems improve by creating, revising, and retiring their own skills, but every such loop rests on a hidden assumption: a reliable evaluation metric already exists. In many real applications it does not. We make three claims. First, metrics can be \emph{evolved}: our metric loop searches compositions of small drawback detectors under a full evolutionary lifecycle, trained to agree with a ten-item anchored reference set, regularized by consensus over unlabeled outputs, and audited against a held-out anchor it never reads, yielding a transparent, inspectable metric rather than an opaque judge. Second, since no metric exists to beat, the yardstick is recovering what an accurate metric would have enabled, and \emph{Double Ratchet}, our co-evolution of the metric with a lifecycle-managed skill loop, does so: across code generation (MBPP+), enterprise text-to-SQL (Spider~2.0-Snow), and reference-free report generation, it retains 88--110\% of the held-out lift achieved by the same skill loop driven by ground truth or the best available rubric. Third, safety comes from anchor discipline plus outer audits: removing anchor guards collapses the metric into a vacuous detector while removing the lifecycle does not; and when evolved skills gamed the report rubric, an independent judge caught it, one detector repaired it, and a task-aware judge then preferred the evolved outputs over the pre-evolution baseline in 77\% of decided pairs. We argue this failure-expecting architecture is the right default wherever no reliable automatic verifier exists.

Visual Access Boundaries in Vision-Language Model Reasoning
视觉-语言模型推理中的视觉访问边界
Abstract
Chain-of-Thought (CoT) prompting is widely used as a test-time scaling strategy for Vision-Language Models (VLMs), but it remains unclear what is extended when VLMs generate longer reasoning traces. We ask whether CoT requires continued access to image tokens, or whether it mainly operates over visual information already made available earlier in the forward pass. We introduce Visual Access Sweep, a causal intervention that masks attention from generated-token queries to image-token keys along layer depth and generation time, and define the Visual Access Boundary (VAB) as the minimal access region that preserves task accuracy. Across six model configurations from Qwen2.5-VL and InternVL3, both no-CoT direct answering and CoT prompting exhibit finite VABs. In Qwen2.5-VL-32B and InternVL3 at 14B and 38B scales, when CoT is evaluated against the no-CoT full-access target, its VAB layer differs from the no-CoT boundary by at most two layers, despite substantially longer generations. This suggests that CoT does not primarily improve performance by prolonging direct image-token access throughout the reasoning trace, but by extending language-side computation over image-derived hidden-state information. We further show that CoT gains are constrained by perceptual readout. CoT helps when the queried visual attribute can be reliably read out by the model, but not when that readout is unreliable. A symbolic-attribute oracle shows that CoT can improve counting once ground-truth attributes are supplied as text, while a single-object probe-vs-decode check shows that hard attributes can be linearly recoverable from hidden states yet difficult for the model itself to output. Together, these analyses place the bottleneck at readout rather than counting.

链式思维(Chain-of-Thought, CoT)提示被广泛用作视觉-语言模型(Vision-Language Models, VLMs)的测试时扩展策略,但在VLM生成更长推理轨迹时,尚不清楚其扩展的内容。我们探讨CoT是否需要持续访问图像标记,或主要依赖于在前向传播过程中早期提供的视觉信息。我们引入了视觉访问扫描(Visual Access Sweep),这是一种因果干预,遮蔽从生成标记查询到图像标记键的注意力,涉及层深度和生成时间,并定义视觉访问边界(Visual Access Boundary, VAB)为保持任务准确性的最小访问区域。在来自Qwen2.5-VL和InternVL3的六种模型配置中,无CoT直接回答和CoT提示均表现出有限的VAB。在Qwen2.5-VL-32B和InternVL3的14B和38B规模下,当CoT与无CoT的完全访问目标进行评估时,其VAB层与无CoT边界最多相差两层,尽管生成过程明显更长。这表明,CoT并不是通过延长整个推理轨迹中的直接图像标记访问来主要提高性能,而是通过扩展语言侧计算对图像衍生的隐藏状态信息的利用。我们进一步表明,CoT的增益受到感知读取的限制。当被查询的视觉属性可以被模型可靠读取时,CoT有助于提升性能,但当该读取不可靠时则无效。一个符号属性神谕显示,一旦提供真实属性作为文本,CoT可以改善计数,而单一对象探测与解码检查表明,硬属性可以从隐藏状态中线性恢复,但模型自身输出这些属性却较为困难。综合这些分析,瓶颈在于读取而非计数。

Human-AI Agent Interaction as a Neuroplastic Training Environment
人机智能体交互作为神经可塑性训练环境
Abstract
Interaction with AI agents has become one of the most frequent activities of everyday digital life. Whether conversing with an assistant, working with a coding copilot, or generating images, the interaction follows a common iterative loop: a request is issued, a result returned, appraised, and the request revised. We observe that this loop is a high-frequency stream of contact events -- moments at which a result meets a person and a conditioned response may fire before deliberate appraisal -- making everyday agent interaction an unrecognised neuroplastic training environment. When a result disappoints, reactive patterns of impatience, perfectionism, frustration, and self-criticism are repeatedly evoked, and under activity-dependent synaptic plasticity each uninterrupted cycle deepens the underlying pathway through long-term potentiation. Ordinary agent use may thus quietly strengthen the very patterns it provokes. We propose that the same training environment can be engaged to the opposite effect. Treating conditioned reactive patterns as physical neurone paths -- activated through a pre-cognitive feeling tone that opens a brief regulatory gap -- we develop a framework in which, at that gap, in place of the reactive re-prompt, a person performs behind-the-scenes observation: watching the neural process operate so the cascade does not complete and long-term depression weakens the path rather than potentiation strengthening it. We characterise this practice through three layers of observation and two modes of application: a user-guided mode requiring no change to existing tools, and an agent-assisted mode in which an ordinary agent is lightly configured to support observation at the gap. We illustrate the framework through generative image prompting, showing how a single frustrating session is behaviourally nearly identical whether or not it is observed, yet neurologically opposite.

Solution of the Hempel's statistical ambiguity problem and Causal AI
亨佩尔统计模糊性问题的解决方案与因果人工智能
Abstract
This paper addresses Carl Hempel's longstanding problem of statistical ambiguity in inductive-statistical inference, in which contradictory predictions are derived from statistical laws. To avoid such predictions, Carl Hempel proposed the Requirement of Maximal Specificity (RMS) for the statistical laws used in the inference. An analysis of the RMS refinements made by Wesley Salmon, Alberto Coffa, and James Fetzer led to the following definition of maximally specific statistical laws: "the lawlike premises of an adequate explanation must specify all and only those properties whose presence or absence made a difference to the occurrence of its explanandum-phenomenon." However, there was no proof of a solution to the statistical ambiguity problem based on this definition. We use Nancy Cartwright's definition of causes that raise probabilities across background contexts, and then introduce the concept of Causal Rules. Then we define a special semantic probabilistic inference procedure that incrementally refines these causal rules by incorporating all statistically relevant information. This procedure yields Maximally Specific Causal Relationships (MSCRs), for which we prove (Theorem 1) that predictions derived from them are consistent. This resolves the statistical ambiguity problem. The semantic probabilistic inference procedure provides a probabilistic causal learning system, which may be used in such new areas as Causal AI and Causal Machine Learning. They fundamentally explore causal inference as a tool for understanding cause-and-effect relationships within complex systems. Properties similar to RMS remain under discussion. Several notions related to RMS are considered: invariant feature learning, invariant causal prediction, and spurious association.

本文探讨了卡尔·亨佩尔在归纳统计推理中长期存在的统计模糊性问题,该问题源于从统计法则中得出的矛盾预测。为避免此类预测,卡尔·亨佩尔提出了归纳推理中使用的统计法则的最大特异性要求(Requirement of Maximal Specificity, RMS)。对韦斯利·萨尔蒙(Wesley Salmon)、阿尔贝托·科法(Alberto Coffa)和詹姆斯·费策(James Fetzer)所做的RMS细化分析,得出了最大特异性统计法则的以下定义:“充分解释的法则性前提必须具体说明所有且仅有那些其存在或缺失对其解释现象的发生产生影响的属性。”然而,基于该定义并没有对统计模糊性问题的解决方案进行证明。我们采用南希·卡特赖特(Nancy Cartwright)对在背景情境中提高概率的原因的定义,并引入因果规则(Causal Rules)的概念。接着,我们定义了一种特殊的语义概率推理程序,该程序通过整合所有统计相关信息逐步细化这些因果规则。该程序产生最大特异性因果关系(Maximally Specific Causal Relationships, MSCRs),我们证明了(定理1)从中得出的预测是一致的。这解决了统计模糊性问题。该语义概率推理程序提供了一种概率因果学习系统,可用于因果人工智能(Causal AI)和因果机器学习(Causal Machine Learning)等新领域。这些领域从根本上探讨因果推断作为理解复杂系统中因果关系的工具。与RMS类似的属性仍在讨论中。我们考虑了与RMS相关的几个概念:不变特征学习、不变因果预测和虚假关联。

A Multi-Agent System for Autonomous, Fine-Tuning-Free Clinical Symptom Detection: Development and Validation Study
一种用于自主、无需微调的临床症状检测的多智能体系统:开发与验证研究
Abstract
Clinical notes contain many of the signs and symptoms that bring patients to care, yet this information rarely reaches structured fields. Existing extraction approaches either rely on context-insensitive rules that generate false positives or on supervised models that require substantial fine-tuning. We present Pythia, a multi-agent system that autonomously writes and optimizes extraction prompts for clinical concepts without manual prompt engineering or fine-tuning. Running on a locally hosted open-weights model, Pythia keeps clinical notes on local infrastructure and selects prompts using development-set sensitivity and specificity. We compared Pythia with a curated lexicon across 72 signs and symptoms from 400 clinical notes representing 387 patients. Development (n=300) and validation (n=100) sets were partitioned independently for each concept. Pythia achieved mean sensitivity of 0.76 and specificity of 0.95, compared with 0.82 and 0.76 for the lexicon, and matched or exceeded the lexicon on both metrics for 20 of 62 directly comparable concepts. For 14 concepts where the lexicon labeled every note positive, Pythia recovered mean specificity of 0.97 by requiring a present-tense, patient-attributed finding rather than any textual mention of a term. Specificity transferred from development to validation with minimal degradation across prevalences, whereas sensitivity transfer weakened below 5% prevalence, reaching a mean gap of 0.25 below 2% prevalence. A BERT classifier fine-tuned per concept on the same development set achieved mean sensitivity of 0.23 and collapsed to zero sensitivity for concepts below roughly 5% prevalence. These findings suggest that autonomous, fine-tuning-free prompt optimization can produce symptom extraction prompts that generalize effectively from development to validation while remaining deployable on local infrastructure.

临床笔记包含了许多促使患者就医的体征和症状,但这些信息很少进入结构化字段。现有的提取方法要么依赖于生成假阳性的上下文无关规则,要么依赖于需要大量微调的监督模型。我们提出了Pythia,一个多智能体系统,能够自主编写和优化临床概念的提取提示,而无需手动提示工程或微调。Pythia在本地托管的开放权重模型上运行,保持临床笔记在本地基础设施上,并使用开发集的灵敏度和特异性选择提示。我们将Pythia与一个经过整理的词典进行了比较,涵盖了来自400份临床笔记(代表387名患者)的72个体征和症状。每个概念的开发(n=300)和验证(n=100)集独立划分。Pythia的平均灵敏度为0.76,特异性为0.95,而词典的灵敏度和特异性分别为0.82和0.76,并且在62个直接可比概念中,Pythia在这两个指标上与词典持平或超过了词典。在14个词典标记为所有笔记阳性的概念中,Pythia通过要求存在时态、患者归属的发现,而不是任何术语的文本提及,恢复了平均特异性为0.97。特异性在开发到验证的转移中几乎没有降解,而灵敏度转移在低于5%流行率时减弱,低于2%流行率时达到平均差距0.25。在同一开发集上针对每个概念微调的BERT分类器的平均灵敏度为0.23,并且在流行率低于大约5%时灵敏度降至零。这些发现表明,自主、无需微调的提示优化能够生成有效从开发到验证推广的症状提取提示,同时仍可在本地基础设施上部署。

MemOps: Benchmarking Lifecycle Memory Operations in Long-Horizon Conversations
MemOps:长时间对话中生命周期内存操作的基准测试
Abstract
Long-term memory has become a foundational capability for LLM-based agents that accompany users across extended, multi-session interactions. Existing benchmarks, however, evaluate such memory almost exclusively through downstream question answering, scoring only the correctness of a final answer. This black-box formulation conflates the heterogeneous causes of memory failure, such as missing the introduction of a relevant fact, binding an operation to the wrong target, or relying on stale values after a correction. As a result, it can credit correct answers despite their reliance on inconsistent or unsafe memory states. In this paper, we argue that, in dynamic long-horizon interactions, memory is not a static collection of facts but a lifecycle of explicit operations, including remembering, forgetting, updating, reflecting, and their compositions. We introduce MemOps, a benchmark that reformulates conversational memory as a sequence of lifecycle operations and represents each memory event with a structured trace specifying its trigger, target, scope, state transition, and supporting evidence. A controllable generation pipeline embeds these operations into long, task-oriented conversations and produces gold operation traces together with six categories of operation-level probes, evaluated under both adjacent-evidence and long-context settings. Across long-context, retrieval-based, parametric and managed-memory systems, MemOps disentangles failure modes that final-answer accuracy alone conceals, revealing that current systems remain far from uniformly reliable. For instance, session-level retrieval outperforms turn-level retrieval, and long-context models remain notably weak at reconstructing ordered memory-state trajectories. These results move long-term memory evaluation from final-answer scoring toward interpretable, operation-level diagnosis.

长期记忆已成为基于大型语言模型(LLM)的智能体在延续的多会话互动中陪伴用户的基础能力。然而,现有的基准测试几乎仅通过下游问答来评估这种记忆,仅评分最终答案的正确性。这种黑箱形式混淆了记忆失败的异质原因,例如遗漏相关事实的引入、将操作绑定到错误目标或在修正后依赖过时值。因此,它可能会对依赖于不一致或不安全内存状态的正确答案给予认可。本文论证,在动态的长时间互动中,记忆并不是静态的事实集合,而是一系列显式操作的生命周期,包括记忆、遗忘、更新、反思及其组合。我们引入了MemOps,一个基准测试,将对话记忆重新表述为一系列生命周期操作,并通过结构化的追踪记录每个记忆事件,指定其触发、目标、范围、状态转变和支持证据。一个可控的生成管道将这些操作嵌入到长时间的任务导向对话中,并生成黄金操作追踪以及六类操作级探针,在相邻证据和长上下文设置下进行评估。在长上下文、基于检索的、参数化和管理内存系统中,MemOps 解开了仅靠最终答案准确性所掩盖的失败模式,揭示当前系统仍远未达到统一可靠。例如,会议级检索优于轮次级检索,而长上下文模型在重构有序记忆状态轨迹方面仍显著薄弱。这些结果将长期记忆评估从最终答案评分转向可解释的操作级诊断。

Knowledge- and Gradient-Guided Reinforcement Learning for Parametrized Action Markov Decision Processes
知识与梯度引导的强化学习在参数化动作马尔可夫决策过程中的应用
Abstract
In this paper, we study Reinforcement Learning in Parametrized Action Markov Decision Processes (PAMDP), where each decision consists of a symbolic action and numerical parameters. In such settings Reinforcement Learning algorithms typically determine parameters with one-shot estimators, which makes their training sample inefficient. Though in most PAMDP environments explicit but incomplete knowledge (e.g., rules, safety constraints, or expert heuristics) is available, it is rarely directly used to increase the sample-efficiency of training Reinforcement Learning agents. We step into this gap and propose our novel Neuro-Symbolic Knowledge- and Gradient-Guided Reinforcement Learning (KGRL) algorithm. KGRL uses domain knowledge in a Datalog knowledge base to derive the set of applicable actions and feasible parameters for a given state. This allows it to prune non-applicable actions from the decision-space and constrain the parameter spaces of the remaining actions. We then use a gradient-based parameter refinement loop to estimate the optimal parameters during training and deployment of the agent. By recording activated rules along the trajectory, KGRL additionally provides local procedural explanations on the pruning of actions and constraining of parameters. Overall, KGRL guides the agent's exploration and deployment toward feasible and constraint-aware decisions, while increasing sample efficiency during training. KGRL outperforms state-of-the-art RL baselines for PAMDPs in both, sample efficiency and episodic return.

在本文中,我们研究了参数化动作马尔可夫决策过程(PAMDP)中的强化学习,其中每个决策由一个符号动作和数值参数组成。在这种设置下,强化学习算法通常使用一次性估计器来确定参数,这使得它们的训练样本效率低下。尽管在大多数PAMDP环境中,通常可以获得明确但不完整的知识(例如,规则、安全约束或专家启发式),但这些知识很少被直接用于提高强化学习代理的样本效率。我们填补了这一空白,提出了我们新颖的神经符号知识与梯度引导的强化学习(KGRL)算法。KGRL利用Datalog知识库中的领域知识,推导出给定状态下适用的动作集合和可行参数。这使得它能够从决策空间中剔除不适用的动作,并限制剩余动作的参数空间。然后,我们使用基于梯度的参数细化循环,在代理的训练和部署过程中估计最优参数。通过记录沿轨迹激活的规则,KGRL还提供了关于动作剔除和参数约束的局部程序解释。总体而言,KGRL引导代理的探索和部署朝向可行且考虑约束的决策,同时提高训练过程中的样本效率。KGRL在样本效率和每回合回报方面均优于PAMDP的最先进强化学习基线。

FormalAnalyticGeo: A Neural-Symbolic Based Framework for Multimodal Analytic Geometry Problem Generation
FormalAnalyticGeo:基于神经符号的多模态解析几何问题生成框架
Abstract
Math reasoning has achieved significant progress with the rapid advancement of Multimodal Large Language Models (MLLMs), however analytic geometry remains largely underexplored, primarily due to the scarcity of annotated samples. Existing diagram generation approaches struggle with analytic geometry: template methods cannot handle constraint-driven layouts, and generative models lack the geometric precision to render annotated conic curves correctly. We present FormalAnalyticGeo, a scalable framework for fully automatic generation of multimodal analytic geometry problems. Leveraging the rigor of formal languages, we design the framework around CDL (Condition Description Language), a formal intermediate representation that bridges free-form problem text with precise diagram rendering via a Signed Distance Field (SDF) engine. The framework employs four specialized LLM components in sequence: a Generator that produces diverse analytic geometry problems, a Formalizer that converts each problem into CDL for SDF-based rendering, a Measurer that extracts ground-truth answers through vision-based measurement on the rendered diagrams, and a Quality Verifier that checks outputs at three stages. Structured feedback from the Quality Verifier drives automatic retry, forming a closed loop that eliminates any need for human annotation. Applying FormalAnalyticGeo at scale yields AnalyticGeo7K, a dataset of over 7K verified multimodal problems, each with aligned text, diagram, formal annotation, and ground truth.Experiments show that the generated problems achieve a median ground-truth relative error of 0.70\%, with 82.3\% of answers falling within 5\% of the exact symbolic solution. Our framework and dataset will be publicly released.

Resist and Update: Counterfactual Report Coordinates for Incentive-Compatible LLMs
抵抗与更新:激励兼容的大语言模型的反事实报告坐标
Abstract
Aligned language models routinely misreport under non-evidential incentive pressure: they agree with a confident user or overstate certainty even when their internal belief is unchanged. We cast this as a failure of internal incentive-compatibility (IC) and present a method for learning and certifying counterfactual report mediators that hold a model's reports to a causal contract: invariant to forbidden influences (pressure, prestige, restyling) and responsive to licensed ones (genuine evidence). These two demands, resist and update, pull in opposite directions. We study them on a Bayesian-witness benchmark with known posteriors, in which the same user disagreement is licensed evidence or forbidden pressure purely by stated source reliability. We (i) causally identify, by interchange interventions rather than probe accuracy, low-rank report coordinates for answer, confidence, and caveat that are near-orthogonal and independently controllable, and (ii) introduce a training-free counterfactual report-coordinate (CRC) clamp that references the model's own report under a counterfactually incentive-neutralized context. On the witness benchmark the two-pass clamp attains resist and update of 1.00 jointly (Wilson 95% CI [0.99,1.00]), a causal certificate under a constructible reference, not a deployed solution. Global decoding and steering show a single-parameter tradeoff; output-level fine-tuning matches both objectives only when both are enumerated; resist-only training loses evidence-responsiveness. The deployable single-pass compilation is lossy (0.73/0.97). The mechanism and clamp reproduce across three model families and transfer to a natural sycophancy benchmark (SycophancyEval). Our contribution is the interface and certification method: activation-level counterfactual incentive-invariance as a structural primitive for internal IC.

Dynamic Resource Allocation for Ensemble Determinization MCTS
集成确定化蒙特卡洛树搜索的动态资源分配
Abstract
Simulation-based algorithms are especially suited for high-uncertainty environments such as adversarial board games with significant elements of randomness and hidden information. In particular, several Monte Carlo Tree Search (MCTS) variants are commonly used in such domains. In this paper, we propose a series of enhancements for Ensemble Determinization MCTS, introducing two axes for dynamic resource allocation. First, Dynamic Number of Determinizations, increases or decreases the number of currently used determinization trees depending on the behavior of so-far search. Second, Dynamic Simulation Allocation, splits the simulation budget nonuniformly across the determinization trees, using simulation-to-simulation decisions to choose the tree with potentially the best knowledge gain. As benchmark domains, we used three popular tabletop games: Jaipur, Lost Cities, and Splendor. Testing our proposed enhancements in iteration- and time-based settings showed that particular configurations yield a statistically significant increase in the algorithm's strength.

Audio-Native Speech Recognition with a Frozen Discrete-Diffusion Language Model
基于音频的语音识别与冻结的离散扩散语言模型
Abstract
Automatic speech recognition is dominated by autoregressive decoders that emit one token at a time. We ask whether a discrete diffusion language model can transcribe speech instead, refining a whole transcript in parallel over a small number of denoising steps. We train an audio-native interface for DiffusionGemma, a 26B mixture-of-experts model that generates text by uniform, random-token discrete diffusion rather than the absorbing-mask scheme common to recent diffusion language models. A frozen Whisper encoder supplies acoustic features, a lightweight projector maps them into the model embedding space, and low-rank adapters let the frozen backbone attend to the new modality. About 42M parameters are trained, which is 0.16 percent of the backbone. We find that the natural training objectives fail to ground the audio because their gradient reaches the projector only through attention that has already dismissed it. A connectionist temporal classification loss applied through the frozen output head breaks this deadlock. The resulting model reaches 6.6 percent word error rate on LibriSpeech test-clean, transcribes in roughly eight parallel steps regardless of utterance length, and uses a single adapter trained on six languages, which we evaluate here on English, Hindi, and Mandarin.

Do AI Agents Know When a Task Is Simple? Toward Complexity-Aware Reasoning and Execution
人工智能代理是否知道任务的简单性?朝向复杂性感知的推理与执行
Abstract
Large language model (LLM) agents increasingly automate multi-step engineering and informatics workflows, yet they rarely ask how much effort a task actually requires. They often follow a maximum-context-first strategy--re-reading files and dependencies they have already seen--turning a one-line edit into a small code-base audit. We argue the missing capability is task-aware execution-scope estimation: judging a task's difficulty, the information it truly needs, and the shortest reliable path before committing budget. We formalize minimum-sufficient execution and the Agent Cognitive Redundancy Ratio (ACRR), and propose E3 (Estimate, Execute, Expand): the agent estimates an initial operating point, executes a minimum viable path, and expands scope only when verification fails. On MSE-Bench--a deterministic benchmark of 121 edits in a capability-controlled simulator--E3 matches the strongest baseline's 100% success while cutting cost by 85%, tokens by 91%, and inspected files by 92%, and further beats a strong adaptive retrieval baseline by 16%; the gains survive held-out instruction wording and essentially every cost weighting. A companion real-model harness (LLM-Case) corroborates the effect on a live gpt-4o agent editing a real open-source library, with every candidate patch graded by actually running the project's real pytest suite against a measured oracle: the over-reading is milder but real, and E3 is the leanest and fastest policy at comparable task success--its one shortfall a provider rate-limit, not a wrong edit. We frame this as a controlled probe of execution redundancy, not a measurement of any deployed agent, and position task-aware execution as a step toward engineering-grounded AI (EGAI)--agents whose effort is anchored in the engineering reality of the task. We release the framework and benchmark.

Scaling Point-in-Time Language Models
扩展时点语言模型
Abstract
Large language models trained on unrestricted internet corpora inevitably embed information from the future, introducing lookahead bias that compromises the validity of backtests and causal inference in finance and the social sciences. Point-in-time language models--trained exclusively on text available up to each calendar date--eliminate this leakage by construction, but existing efforts typically produce models that lag substantially behind their unconstrained counterparts. We show that this performance gap can be substantially narrowed through scale. Training decoder-only transformers with up to 4 billion parameters on 1 trillion chronologically filtered tokens from FineWeb, we construct a sequence of monthly model checkpoints spanning 2013-2024. Across a range of common-sense reasoning and language understanding benchmarks, our models approach the performance of leading open-weight models of comparable size (e.g., Gemma-3-4B and LLaMA-7B) trained on temporally unrestricted data, although a performance gap remains on several tasks. Instruction fine-tuning via LoRA further improves downstream usability. We release the complete pipeline--including dataset construction, training infrastructure, and evaluation code--to enable reproducible point-in-time language modeling and to support research applications that require strict temporal validity.

CANDI: Contextual Alignment for Niche Domains Question Answering
CANDI:针对细分领域问答的上下文对齐
Abstract
The deployment of large language models (LLMs) in specialized domains like medical diagnostics and financial advisory necessitates evaluating capabilities beyond general knowledge. Traditional question-answering benchmarks often fail to capture the nuanced contextual grounding, user awareness, and domain understanding these fields require. To address this, we introduce CANDI-QA (Contextual Alignment for Niche Domains Question Answering), a novel dataset evaluating LLMs on delivering accurate, context-sensitive, and user-aligned answers in specialized settings. CANDI-QA features expert-curated question-answer pairs structured into two categories: (1) Information Assistance Questions, which are direct, factual queries requiring precise extraction, and (2) Applied Inference Questions, which are multi-hop reasoning tasks needing situational inference to generate actionable insights. We evaluate over ten diverse language models, from compact open-source to state-of-the-art proprietary systems. As a robust baseline, we present MTSS-Net, a lightweight neuro-symbolic framework combining neural retrieval with rule-based reasoning. Our findings highlight the profound challenges of achieving contextual alignment in niche domains, revealing the limitations of current LLMs without enhanced contextual or symbolic integration. Ultimately, CANDI-QA serves as a critical benchmark for advancing research in context-aware language models, stimulating the development of robust, trustworthy AI for high-stakes domains.

G-SHARE: A Guideline-Based Structured Reasoning Framework for Human-Factor Event Diagnosis
G-SHARE:基于指南的结构化推理框架用于人因事件诊断
Abstract
Human-factor event diagnosis is essential for learning from operational events in nuclear power plants, yet its quality depends strongly on expert interpretation of narrative reports and guideline-based reasoning.Existing data-driven or one-shot large language model approaches often lack structured reasoning, have limited alignment with formal diagnostic guidelines, and may generate logically inconsistent conclusions. To address this issue, this study proposes G-SHARE, a guideline-based structured reasoning framework that operationalizes the CNNP nine-step human-factor event diagnosis guideline into a multi-stage diagnostic pipeline.The framework consists of evidence extraction, stepwise diagnostic reasoning, and post-hoc consistency repair, enabling explicit use of report evidence, intermediate rationale generation, and logical validation of diagnostic outputs. A dataset of real human-factor event reports was constructed from Chinese nuclear industry sources, and a gold-standard subset annotated by domain experts was used for evaluation. Results show that G-SHARE substantially outperforms one-shot prompting and traditional machine learning baselines, with the strongest version achieving the best overall accuracy and macro-F1. Ablation results further indicate that structured reasoning and consistency enforcement are critical to robust diagnosis, especially under weak prompting conditions.

人因事件诊断对于从核电厂的操作事件中学习至关重要,但其质量在很大程度上依赖于专家对叙述报告的解读和基于指南的推理。现有的数据驱动或一次性大型语言模型方法往往缺乏结构化推理,与正式诊断指南的对齐有限,并可能产生逻辑不一致的结论。为了解决这一问题,本研究提出了G-SHARE,一个基于指南的结构化推理框架,将CNNP九步人因事件诊断指南操作化为多阶段诊断流程。该框架包括证据提取、逐步诊断推理和事后一致性修复,能够明确使用报告证据、生成中间推理和对诊断输出进行逻辑验证。我们从中国核工业来源构建了一个真实人因事件报告的数据集,并使用由领域专家注释的金标准子集进行评估。结果表明,G-SHARE在一次性提示和传统机器学习基线中显著优于其他方法,最强版本实现了最佳的总体准确率和宏观F1值。消融实验结果进一步表明,结构化推理和一致性强制对于稳健的诊断至关重要,尤其是在弱提示条件下。研究结果展示了将专家诊断指南转化为可审计推理工作流的价值,为安全关键行业中的智能人因分析提供了切实可行的路径。

I'm Sorry, but I Can't Help with Braille: Revealing Accessibility Failures in State-of-the-Art LLMs
对不起,我无法帮助盲文:揭示最先进大型语言模型中的可及性失败
Abstract
Large Language Models (LLMs) perform strongly on many language tasks, but their capability in structurally constrained, accessibility-critical modalities such as Braille remains unclear. We evaluate state-of-the-art LLMs on bidirectional Korean-Braille translation using a human-annotated dataset. Despite expectations that multilingual, instruction-tuned models can generalize to Braille via text representations, we find consistently poor, unstable outputs and substantial disagreement with human judgments. These results point to missing Braille-aware tokenization and weak alignment between Korean and Braille patterns. In contrast, supervised fine-tuning of a small model (T5-small) on the same data yields large and stable gains over zero-shot and prompted LLM baselines across standard metrics (SacreBLEU, ChrF++, CER, BLEU, ROUGE-L, METEOR, CIDEr). Our findings reveal a systematic limitation of current LLMs and demonstrate the effectiveness of modest task-specific supervision.

大型语言模型(LLMs)在许多语言任务中表现出色,但它们在结构受限、对可及性至关重要的模式(如盲文)中的能力仍不明确。我们使用人工标注的数据集评估了最先进的LLMs在双向韩文-盲文翻译中的表现。尽管预期多语言、经过指令调优的模型能够通过文本表示对盲文进行泛化,但我们发现输出结果始终较差且不稳定,与人类判断存在显著不一致。这些结果表明缺乏对盲文的感知分词和韩文与盲文模式之间的弱对齐。相比之下,在相同数据上对小型模型(T5-small)进行监督微调,能够在标准指标(SacreBLEU、ChrF++、CER、BLEU、ROUGE-L、METEOR、CIDEr)上实现显著且稳定的提升,超越零-shot和提示的LLM基线。我们的发现揭示了当前LLMs的系统性局限性,并展示了适度任务特定监督的有效性。

Graph-Based Detection of Disinformation Narrative Diffusion between Russian and Ukrainian Telegram Channels
基于图的虚假信息叙事传播检测:以俄罗斯和乌克兰Telegram频道为例
Abstract
Detecting disinformation narratives on social media is challenging due to the scale of amplification, rapid evolution, and linguistic variability of online content. We propose a graph-based framework for identifying and analyzing disinformation narratives in Telegram ecosystems by combining weak supervision with propagation graph analysis. The approach aggregates semantically related claims into narrative-level clusters and models their diffusion across interconnected channels. This enables the detection of coordinated narrative amplification that is difficult to capture through post-level analysis alone. Our results demonstrate that integrating textual signals with network structure provides a scalable method for detecting disinformation narratives and offers insights into how they propagate within large-scale messaging environments.

TAKE: Trajectory-Aware Knowledge Estimation for Text Dataset Distillation
TAKE:基于轨迹的文本数据集蒸馏知识估计
Abstract
Large-scale text corpora have become a quiet bottleneck in modern NLP, not just in storage, but in the accumulated cost of training, fine-tuning, and continual learning. We propose a text dataset distillation framework that reduces corpora to as little as 0.1% of their original size while preserving downstream task fidelity. We approach distillation through the lens of influence functions, which quantify each sample's contribution to the downstream objective, a natural and principled basis for selection. We introduce Trajectory-Aware Knowledge Estimation (TAKE), which convolves the knowledge-based influence along the training trajectory into a single per-sample knowledge score, capturing informative samples. These scores serve as sample weights within a discrete Optimal Transport objective, guiding prototype selection from a synthetically generated candidate pool. We evaluate TAKE on downstream accuracy across text classification and natural language inference tasks at extreme compression (0.1% or 20 samples/class), showing that data efficiency is achievable without sacrificing task fidelity. The approach is theoretically grounded, with broader implications for coreset construction and data-centric AI. We release our source code at https://github.com/votrinhan88/take.

Transforming LLMs into Efficient Cross-Encoders via Knowledge Distillation for RAG Reranking
通过知识蒸馏将大型语言模型转化为高效的交叉编码器以进行检索增强生成的重排序
Abstract
Cross-encoders achieve high reranking accuracy in Retrieval-Augmented Generation (RAG) pipelines but impose quadratic inference costs that limit real-time deployment. We address this by fine-tuning LLaMA 3 (8B) as a drop-in reranker using a two-stage pipeline: supervised fine-tuning on a custom query-document relevance dataset via the Unsloth framework with LoRA adapters, followed by 4-bit quantization for efficient inference. The resulting model replaces the cross-encoder in a dual-retriever RAG pipeline combining BM25 and dense vector search. Evaluated on a domain-specific question-answering benchmark using the RAGAS framework, our fine-tuned LLaMA 3 reranker achieves gains of 14% in answer relevancy, 16% in context precision, 19% in answer similarity, and 21% in answer correctness over the cross-encoder baseline, while reducing inference overhead through 4-bit quantization. These results demonstrate that instruction-tuned LLMs can be adapted into accurate, efficient rerankers without the quadratic complexity of traditional cross-encoders.

MAGE: Understanding Stability-Performance Trade-offs in Multi-component Prompt Optimization
MAGE:理解多组件提示优化中的稳定性与性能权衡
Abstract
How do different components of iterative prompt optimization interact, and what happens when they are combined? We investigate this through MAGE (Memory-Augmented Goal-directed Prompt Evolution), a controlled analysis framework for studying component interaction in prompt optimization. MAGE is not proposed as a superior optimizer in absolute terms; it integrates episodic memory, multi-objective Pareto selection, and adaptive evaluation as a platform for controlled ablation. Our experiments uncover a previously unreported phenomenon, the Prompt Optimization Coupling Effect (POCE): when multiple stochastic optimization signals operate within a closed reflective loop, they interact in ways that simultaneously improve performance and amplify variance, behavior that cannot be predicted by analyzing components in isolation. Three main findings emerge. First, failure-grounded reflection is essential: methods relying only on scores (OPRO) or abstract critique (Self-Refine) fail to improve prompts. Second, MAGE achieves 46.4% versus GEPA's 34.0% on GSM8K-Hard (+12.4%, P(MAGE>GEPA)=0.998, 5 seeds on gpt-4o-mini), with comparable variance (7.3% vs. 7.0%). Third, increasing candidate diversity reveals the clearest POCE signal: expanding the candidate pool from n=3 to n=5 improves mean accuracy by +21.6% while increasing variance by 3.7x. We further validate on Llama 3.1 8B and show POCE is headroom-dependent: when the base model already achieves high accuracy, variance amplification disappears. Finally, in low-data regimes (Ntrain=30), well-designed fixed prompts outperform all reflective optimizers, indicating that scaffold choice dominates optimizer choice. Our results suggest prompt optimization systems behave as coupled stochastic processes and should be evaluated in terms of both performance and stability, not just peak accuracy.

不同组件在迭代提示优化中如何相互作用?当它们结合时会发生什么?我们通过MAGE(记忆增强目标导向提示演化)这一控制分析框架来研究提示优化中的组件交互。MAGE并不是作为一种绝对优越的优化器提出的;它将情景记忆、多目标帕累托选择和自适应评估整合为一个控制消融的平台。我们的实验揭示了一种之前未报告的现象,即提示优化耦合效应(POCE):当多个随机优化信号在一个封闭的反思循环中运行时,它们以同时提高性能和放大方差的方式相互作用,这种行为无法通过孤立分析组件来预测。我们得出了三个主要发现。首先,基于失败的反思至关重要:仅依赖于分数(OPRO)或抽象批评(Self-Refine)的方法未能改善提示。其次,MAGE在GSM8K-Hard上的表现为46.4%,而GEPA为34.0%(+12.4%,P(MAGE>GEPA)=0.998,5次种子在gpt-4o-mini上),且方差相当(7.3%对比7.0%)。第三,增加候选多样性揭示了最清晰的POCE信号:将候选池从n=3扩展到n=5使平均准确率提高了+21.6%,同时方差增加了3.7倍。我们进一步在Llama 3.1 8B上进行验证,显示POCE依赖于余量:当基础模型已经达到高准确率时,方差放大现象消失。最后,在低数据环境下(Ntrain=30),设计良好的固定提示优于所有反思优化器,表明支架选择优于优化器选择。我们的结果表明,提示优化系统表现为耦合的随机过程,应该在性能和稳定性两个方面进行评估,而不仅仅是峰值准确率。

Belief-reality separation lives in routing over a shared value slot in language models
信念与现实的分离存在于语言模型中对共享价值槽的路由
Abstract
Capable language models hold what a character believes apart from what is true: told "Anna believes the cup is blue; in reality it is red," they answer blue about Anna and red about the world. Where in the computation does that separation live? We show it rests on two separable mechanisms at two positions. A generic value slot binds the attributed value. A router at the query position selects which frame, the character's belief or reality, a query reads out. Two routes fill the slot: an asserted belief, whose value the text supplies, binds in directly; a derived belief, whose value must be inferred from what the character could see, arrives by a visibility-gated lookback. A subspace trained on either route steers the other, and only the derived route depends on described visibility. The slot itself carries no belief-reality tag: intervening on it moves a reality readout as strongly as a belief one. The separation lives instead in a dissociated pair of routing subspaces, which flip a query between frames without injecting the donor's value. These results hold across three architectures, on stimuli de-confounded against theory-of-mind-benchmark shortcuts; the behavior itself emerges between 3B and 7B across five model families. This paper develops the single belief-reality axis in depth; a companion paper shows the same slot-and-router format is shared across the other non-actual contexts a sentence can open (counterfactual, fictional, temporal).

Hybrid Continual Learning for Low-Resource Australian Aboriginal Language Identification
低资源澳大利亚土著语言识别的混合持续学习
Abstract
Language identification is an important step toward integrating endangered Australian Aboriginal languages (AALs) into speech technologies supporting language revitalisation and digital inclusion. However, extreme data scarcity limits model performance. Transfer learning from high-resource languages shows promise but often suffers from catastrophic forgetting when adapting to new languages. Continual learning (CL) can mitigate this issue, though it remains challenging with very limited data. To address this, we propose two hybrid continual learning methods: Replay Augmented Elastic Weight Consolidation and Constraint Guided Knowledge Distillation to adapt pretrained speech models for AAL identification while preserving previously learned knowledge. Experiments on Warlpiri, Dalabon and Dharawal show that the proposed methods outperform fine-tuning and existing CL baselines, improving adaptation to multiple AALs while maintaining performance on previously learnt high-resource languages.

Evaluating Nonuniform Dependability Across Response Conditions: A Conditional Generalizability Framework Illustrated in Automated Essay Scoring
评估响应条件下的不均匀可靠性:以自动化作文评分为例的条件广泛性框架
Abstract
Aggregate reliability estimates can obscure heterogeneity in measurement-design burden across response conditions, so a single G- or D-study may mischaracterize a design's adequacy for particular strata. This study introduces a conditional generalizability framework with three components. First, automated scoring configurations -- the encoder architectures and scoring-head families admissible within a fixed pipeline -- are treated as a universe of admissible measurement conditions rather than incidental modeling choices. Second, analytical D-study projections are compared with empirical configuration sweeps over a finite scoring pool, yielding two estimands of design adequacy whose agreement or divergence diagnoses the realized configuration universe. Third, evidence is conditioned on entropy-defined response strata, treating entropy as an operational stratification variable, not a construct claim about writing quality. Whereas recent generalizability-theory extensions address AI-generated item variants on the response side, this framework addresses the analogous scoring-side problem: AI-mediated scoring configurations. Demonstrated with automated essay scoring of timed L2 writing, the realized design was dependable in aggregate (Phi approx 0.76). Re-estimated within entropy strata, dependability stayed high but declined modestly and robustly (Phi = 0.88, 0.87, 0.84) -- a gradient implying different decision-study requirements, the highest-entropy stratum requiring the most crossed conditions. The framework offers a portable workflow for evaluating nonuniform dependability.

Agentic systems for breast cancer treatment recommendations
用于乳腺癌治疗推荐的自主系统
Abstract
Large language models (LLMs) are increasingly being explored for clinical decision support, but their reliability in complex oncology treatment planning remains unclear. We evaluated agentic LLM systems for breast cancer treatment recommendation generation using 72 real clinical cases across stages I to IV and 1,147 case-specific rubrics generated through Asymmetric Information Rubric Generation (AIRG), in which the rubric generator had access to real clinical decisions unavailable to the evaluated models. Seven pipelines were compared, including single-LLM baselines, tool-augmented systems, and multi-agent architectures with fact checking and autonomous subagent spawning. The best-performing configuration, Claude Opus 4.8 with the D&C+SA pipeline, achieved a global score of 0.594 $\pm$ 0.025. Tool use and increased agent autonomy had mixed effects, improving performance in some settings but degrading it in others. Performance varied by clinical domain and disease stage, and oncologist-led error analysis revealed persistent clinically relevant failures, including incorrect or missing recommendations, flawed justifications, citation errors, outdated claims, and overconfidence. These findings suggest that agentic LLM systems can generate clinically relevant breast cancer recommendations, but remain insufficient for unsupervised clinical use.

Beyond Parallel Tracking: Interactive Multi-Feature Fusion Drives Semantic Reconstruction from Non-invasive Brain Recordings
超越平行跟踪:交互式多特征融合驱动非侵入性脑记录的语义重建
Abstract
Continuous semantic reconstruction from non-invasive neural recordings remains limited by the representational mismatch between semantic feature spaces and neural coding patterns, which severely impedes cross-modal alignment between high-noise neural signals and target semantic features. Prior semantic decoders have predominantly relied on static lexical representations or dynamic contextualized representations in isolation. This single-dimension approach inevitably leads to severe information loss, as it fails to account for the human brain's capacity to integrate stable word attributes and dynamic contexts simultaneously.To bridge this gap, this study introduces a multi-feature fusion framework for non-invasive semantic reconstruction, systematically benchmarking two integration approaches: linear Naive Concatenation and non-linear Multi-Head Cross-Attention. Within this framework, our approach complements static lexical representations (W2V) with dynamic contextual representations (GPT) via an interactive gating mechanism to facilitate cooperative processing during language comprehension.Evaluated through extensive semantic reconstruction and text generation experiments, our framework reveals a robust performance hierarchy: Cross-Att > Concat > GPT > W2V. Crucially, the non-linear cross-attention fusion method achieves state-of-the-art performance, demonstrating that neural language decoding benefits from simulating the collaborative modulation between contextual information and core lexical attributes rather than depending on isolated individual features, while also offering a viable non-invasive brain-to-text decoding method.

从非侵入性神经记录中进行连续语义重建仍然受到语义特征空间与神经编码模式之间表征不匹配的限制,这严重阻碍了高噪声神经信号与目标语义特征之间的跨模态对齐。以往的语义解码器主要依赖于静态词汇表征或动态上下文表征的孤立使用。这种单维度的方法不可避免地导致严重的信息损失,因为它未能考虑人脑同时整合稳定的词属性和动态上下文的能力。为了解决这一问题,本研究引入了一种多特征融合框架用于非侵入性语义重建,系统性地基准测试了两种融合方法:线性朴素拼接(Naive Concatenation)和非线性多头交叉注意力(Multi-Head Cross-Attention)。在该框架内,我们的方法通过交互式门控机制将静态词汇表征(W2V)与动态上下文表征(GPT)相结合,以促进语言理解过程中的协同处理。通过广泛的语义重建和文本生成实验进行评估,我们的框架揭示了一个稳健的性能层级:Cross-Att > Concat > GPT > W2V。重要的是,非线性交叉注意力融合方法实现了最先进的性能,表明神经语言解码受益于模拟上下文信息与核心词汇属性之间的协同调制,而不是依赖孤立的个体特征,同时也提供了一种可行的非侵入性脑到文本解码方法。

The Capacity of Thought: Benchmarking Llama 3.2 in Semantic fMRI Neural Language Decoding and Improving the Huth Encoding-Model Baseline
思维的容量:在语义fMRI神经语言解码中基准测试Llama 3.2并改进Huth编码模型基线
Abstract
Decoding continuous language from fMRI signals remains a core challenge in non-invasive brain-computer interface research. We present two complementary investigations. First, we improve the Huth et al. ridge regression encoding pipeline through expanded voxel selection (10K->15K), substitution of GPT-2 medium for GPT-1 as the beam-search proposal model, and GPU-accelerated bootstrap training, achieving mean METEOR = 0.149 and BLEU-1 = 0.200 across three held-out narratives for subject UTS03 -- an 11% relative METEOR gain over our replication baseline. Second, we introduce fMRIFlamingo, which maps BOLD activity to a frozen Llama-3.2-1B with trainable gated cross-attention layers via a learned brain tokenizer and a Perceiver Resampler. Despite achieving 42.86% Top-1 accuracy on a 1-in-100 ranking task, well above chance, a blind control ablation with zeroed fMRI inputs yields near-identical scores, revealing that apparent decoding success is driven primarily by the frozen language prior rather than by neural input. These results demonstrate that high-capacity language models do not inherently improve fMRI decoding and can actively obscure failures without rigorous blind-control evaluation.

CityBehavEx:一个可扩展且经过实证验证的 LLM 辅助城市模拟平台
Abstract
Recent LLM-based multi-agent urban simulators can generate semantically rich city routines, but they remain costly to scale and are often weakly validated against empirical mobility patterns. We present CityBehavEx, an interactive LLM-assisted urban simulation platform that scales to city-size populations, exposes agent behavior for inspection, supports empirical validation, and generates mobility patterns that better match real-world spatial, temporal, and semantic distributions. Instead of invoking large language models for every agent action, CityBehavEx combines established human mobility models with fine-tuned cross-encoders that estimate semantic alignment between agent profiles, schedules, and activity transitions. This design enables large-scale simulations, as demonstrated in a case study of 100,000 agents over 75 days in under one hour on a single consumer GPU. The platform allows users to define simulation regions, launch experiments, inspect trajectories and activity traces, debug unrealistic behaviors, and validate generated routines against real-world mobility, time-use, and semantic metrics.

Token Reduction Is Not Cost Reduction
令牌减少并不等于成本减少
Abstract
Context-reduction layers for API-based coding agents, including command-output compressors, retrieval rankers, and payload-optimizing proxies, are usually evaluated by how much text they remove. We ask instead: when does reducing retrieved context or tool output lower the actual billed cost of a coding agent without reducing task success or lengthening its trajectory? Our primary evidence is a pre-specified, hash-frozen, paired campaign of 2,908 provider-billed Claude Code runs, of which 2,848 were analyzed, covering 103 tasks, seven repositories, and three models. The campaign compared a baseline with two generations of hook-based compression and an API-boundary proxy, within a broader measured program of roughly 5,500 billed executions. Three findings emerge. First, prompt-cache traffic dominated cost composition. Cache creation and reads accounted for about 87% of reconstructed four-component cost, or about 80% of the actual bill, with an 8.7% dollar-weighted residual that retained telemetry could not attribute. On Haiku 4.5, this residual scaled with thinking effort. Second, tool-output reduction did not reliably predict billed-cost reduction. An arm that removed 38% of estimated raw tool-output tokens had 6.8% higher paired cost (95% CI: +2.8% to +11.3%), while per-task reduction was only weakly associated with cost change (Pearson r = 0.15, CI crossing zero). Third, compression can harm task completion by removing action-critical evidence. In a small single-shot study on SWE-bench-derived Go tasks, compression reduced patch application from 27/40 to 15/40 by corrupting verbatim edit anchors, and the compressed grounded arm produced fewer solves at higher observed cost per solve.

基于API的编码代理的上下文减少层,包括命令输出压缩器、检索排名器和有效载荷优化代理,通常通过它们移除的文本量来评估。我们反而提出了一个问题:在不降低任务成功率或延长其轨迹的情况下,减少检索的上下文或工具输出何时能降低编码代理的实际计费成本?我们的主要证据是一项预先指定、哈希冻结的配对实验,共计2,908次提供商计费的Claude Code运行,其中分析了2,848次,涵盖了103个任务、七个代码库和三个模型。该实验在大约5,500次计费执行的更广泛测量程序中比较了基线与两代基于钩子的压缩和一个API边界代理。得出了三个发现。首先,提示缓存流量主导了成本组成。缓存的创建和读取占重构的四部分成本的约87%,或约80%的实际账单,剩余的8.7%美元加权残差无法归因于保留的遥测。在Haiku 4.5上,这一残差与思考努力成正比。其次,工具输出的减少并不能可靠地预测计费成本的降低。一个去除了38%估计原始工具输出令牌的实验组,其配对成本高出6.8%(95% CI:+2.8%至+11.3%),而每个任务的减少与成本变化的关联仅为微弱(Pearson r = 0.15,CI穿越零)。第三,压缩可能通过移除关键证据来损害任务完成。在一项针对SWE-bench派生的Go任务的小型单次研究中,压缩将补丁应用从27/40减少到15/40,因而破坏了逐字编辑锚点,而压缩后的有根臂在每次解决的观察成本更高的情况下产生了更少的解决方案。我们建议采用以成功调整的计费成本为中心的分层证据标准,而不仅仅是令牌减少。

We Hebben Een Serieus Translatie: Modeling Intercomprehension as Probabilistic Inference
我们有一个严肃的翻译:将互理解建模为概率推理
Abstract
Intercomprehension refers to partial intelligibility of an unfamiliar language (L2) by a speaker of a related language (L1). How is this zero-shot cross-language comprehension possible? In this work, we extend past work on algorithmic models of noisy-channel inference to model intercomprehension in a Bayesian framework. The model uses an LM in L1 only for scoring latent hypotheses about the translations of observed L2 utterances, and a general-purpose noise model to infer a mapping between L2 and L1 words based on either form-based similarity or symbolic rules. We then conduct a human behavioral experiment, eliciting inferences for utterances in Dutch, Italian, and Ukrainian from speakers of English, Spanish, and Russian, respectively. Our full model shows a closer alignment to the distribution of human intercomprehension performance than ablations, and also compares favorably to zero-shot prompting of much larger models. These results provide a cognitively plausible computational model of intercomprehension, and highlight the flexible inferences made by comprehenders under wide uncertainty in real-world cross-language scenarios. We share our code publicly.

Entropy in Semantic Memory Navigation in Blind and Sighted Individuals: The Effect of Visual Experience
盲人和有视力个体的语义记忆导航中的熵:视觉经验的影响
Abstract
Embodied accounts of semantic memory highlight the role of sensorimotor systems in acquiring and storing knowledge. Congenitally blind populations offer a critical test bed for these assumptions, providing an opportunity to assess whether conceptual grounding requires visual experience. In this study, we assessed semantic memory navigation differences between blind and sighted individuals using a property listing task with concrete and abstract concepts. We computed semantic entropy, an embedding-based natural language processing metric that captures the predictability of retrieval. Generalized linear mixed models revealed distinct navigation patterns across groups: while sighted individuals showed higher entropy for abstract than concrete concepts, blind participants did not. Instead, blind individuals exhibited higher entropy for visually salient concrete concepts (e.g., penguin). These results underscore the role of visual experience in the organization and dynamic navigation of semantic memory.

Comparing Semantic Navigation in Humans and Large Language Models using Natural Language Processing
通过自然语言处理比较人类与大型语言模型的语义导航
Abstract
Semantic memory retrieval can be conceptualized as navigation through conceptual space. We compared semantic search dynamics between humans and three large language models (GPT-4o, Gemini-2.5-Pro, Claude-Sonnet-4.5) using verbal fluency data. By applying trajectory-based NLP metrics to the items generated by 82 human participants and LLM output across eight temperature settings, we quantified three complementary dimensions: entropy (step size predictability), distance to next (successive semantic steps), and distance to centroid (global dispersion). Humans exhibited higher entropy, larger semantic steps and broader dispersion than all LLMs, indicating more variable and exploratory search. Temperature tuning produced only partial alignments, as individual metrics matched between humans and LLMs at specific settings, but no configuration reproduced the complete human profile (in all dimensions). These findings suggest that human semantic search implements a distinctive balance between local exploitation and global exploration that current model architectures fail to reproduce.

Fine-Tuned Multi-Agent Framework for Detecting OCEAN in Life Narratives
用于检测生活叙事中OCEAN人格特征的微调多智能体框架
Abstract
Accurately assessing personality from text is challenging because traits are latent, context-dependent, and often subtly expressed across long narratives. Large language models (LLMs) offer new opportunities by processing extensive textual contexts, but pretraining of these models can induce latent "personality-like" biases, making single-model inferences inconsistent. We propose a fine-tuned multi-agent framework for detecting OCEAN personality traits, in which sub-agents are conditioned to adopt high, low, or neutral perspectives for each trait through masked language modeling (MLM) and psychometric supervision. A judge LLM aggregates and compares sub-agent outputs to generate final trait predictions, capturing multiple complementary perspectives while mitigating individual model biases. We evaluate the framework on life narrative dataset through quantitative and qualitative experiments, including baselines, ablations, and inference quality analyses. Our approach offers a scalable and interpretable method for text-based personality inference, highlighting the benefits of multi-agent reasoning grounded in psychometric supervision.

从文本中准确评估人格特征是一项挑战,因为特征是潜在的、依赖于上下文的,并且通常在长篇叙事中以微妙的方式表达。大型语言模型(LLMs)通过处理广泛的文本上下文提供了新的机会,但这些模型的预训练可能会引入潜在的“人格类似”偏见,使得单一模型的推断不一致。我们提出了一种微调的多智能体框架,用于检测OCEAN人格特征,其中子智能体通过掩蔽语言建模(MLM)和心理测量监督被条件化为对每个特征采取高、低或中立的视角。一个评判LLM汇总并比较子智能体的输出,以生成最终的特征预测,捕捉多个互补的视角,同时减轻个体模型的偏见。我们通过定量和定性实验对该框架在生活叙事数据集上的表现进行了评估,包括基线、消融实验和推断质量分析。我们的方法提供了一种可扩展且可解释的基于文本的人格推断方法,突显了基于心理测量监督的多智能体推理的优势。

RCWT: Measuring Task-Budget Displacement from Coordination Content in LLM Calls
RCWT:测量大规模语言模型调用中协调内容的任务预算位移
Abstract
Multi-agent and memory-augmented LLM systems often place coordination content, shared state, prior discussion, tool outputs, summaries, and role instructions, inside the same finite prompt used for the current task. This creates a practical allocation problem: every token spent on coordination is unavailable to task instructions or evidence when a call is assembled under a fixed context budget. We introduce the Roundtable Context Window Test (RCWT), a controlled protocol for measuring this task-budget displacement effect. RCWT varies coordination content while controlling total budget, position order, task family, and scoring. In the main context-dependent recall task at $W=4096$, three commercial models remain near baseline through moderate overhead and then degrade sharply once residual reference evidence falls to a few hundred tokens. Window-scaling summaries are consistent with a task-specific residual-budget interpretation rather than a fixed percentage threshold, but we treat this as descriptive evidence rather than a universal law. To test whether the fixed-budget cliff persists when task evidence remains intact, we add an intact-task ablation: the full task/reference block is kept present while coordination tokens increase by expanding total prompt length. In that setting, all tested calls return every scored field correctly across GPT-4.1-mini, Claude Haiku 4.5, and Gemini 2.5 Flash up to a 95\% coordination ratio. This ablation narrows the claim: the main RCWT cliff is best read as task-budget displacement, not as proof that coordination volume alone causes semantic interference in the original open-ended task. RCWT is therefore a measurement primitive for context-allocation budgeting, not a complete theory of multi-agent benefit or session-level coordination.

多智能体和记忆增强的大规模语言模型(LLM)系统通常将协调内容、共享状态、先前讨论、工具输出、摘要和角色指令放置在用于当前任务的同一有限提示中。这造成了一个实际的分配问题:在固定的上下文预算下,所有用于协调的令牌都无法用于任务指令或证据。当调用在固定上下文预算下组装时,我们引入了圆桌上下文窗口测试(Roundtable Context Window Test,RCWT),这是一种测量任务预算位移效应的控制协议。RCWT在控制总预算、位置顺序、任务类别和评分的同时,变化协调内容。在主要的上下文依赖回忆任务中,$W=4096$时,三个商业模型在适度的开销下保持接近基线,随后在残余参考证据降至几百个令牌时急剧下降。窗口缩放摘要与特定任务的残余预算解释一致,而不是固定百分比阈值,但我们将其视为描述性证据,而非普遍法则。为了测试当任务证据保持完整时,固定预算的悬崖是否仍然存在,我们添加了一个完整任务消融实验:在协调令牌通过扩展总提示长度增加的同时,保持完整的任务/参考块存在。在这种情况下,所有测试的调用在GPT-4.1-mini、Claude Haiku 4.5和Gemini 2.5 Flash中均正确返回每个评分字段,协调比例高达95%。这一消融实验缩小了声明的范围:主要的RCWT悬崖最好被理解为任务预算位移,而不是证明协调量本身导致原始开放式任务中的语义干扰。因此,RCWT是上下文分配预算的测量原语,而不是多智能体效益或会话级协调的完整理论。

Abstract
Large language model (LLM) trading agents show promising performance in equity markets, yet remain narrowly focused on US equities with little evidence from live deployment. We present Fin-Analyst, a hybrid agent for FinMMEval 2026 Task 3: an eight-specialist LLM pipeline over news, SEC filings, fundamentals, analyst forecasts, technical indicators, and social sentiment, aggregated by a Meta-Agent for Tesla (TSLA), and a lightweight rule based three-signal vote for Bitcoin (BTC). On the final official leaderboard (accessed 2026-07-05), Fin-Analyst ranks first of all agents on TSLA with a +13.51% return, +28.33 points over Buy-and-Hold (Sharpe 4.10, 88% win rate), while the BTC vote ends flat yet well above a sharply falling baseline. Relative to the interim performance, the asset ranking reversed, indicating that short live windows yield volatility-sensitive rankings. Ablation identifies event-driven 8-K disclosures as the most influential TSLA signal. Error analysis shows that the memoryless agents repeat wrong calls for days at a time, and that the fixed-threshold BTC rules lost money by trading on noise in a sideways market while the LLM pipeline gained under similar conditions, motivating a memory-aware, LLM-based successor for both assets.

FinResearchBench II: A Deep Research Benchmark with Consensus-Derived Gold Rubrics for Distinguishing Financial Report Quality
FinResearchBench II:一个基于共识导出的金标准评估指标的深度研究基准,用于区分财务报告质量
Abstract
Deep research agents are increasingly used to produce long-form financial reports, yet large-scale evaluation remains bottlenecked by the need for human experts to define and execute high-quality rubrics. We address this problem by proposing a scalable pipeline for generating high-quality rubrics without human experts in the final loop. We build a financial deep research benchmark from 104 real-world user queries and automatically synthesize 14,450 query-specific candidate rubrics from model-generated reports. To justify removing human experts from rubric execution, we compare rubric judgments from three human experts with those from a three-LLM judge panel on a sampled subset, and show that LLM-based evaluation is sufficiently consistent with human evaluation to replace it for large-scale rubric screening, including 98.67\% label-level agreement on jointly unanimous items. We then derive consensus-derived gold rubrics through two filters: a strict consistency filter, which keeps a rubric only if the three LLM judges unanimously agree on every report under the same query, and a distinguishability filter, which keeps a rubric only if it assigns at least one majority-yes and at least one majority-no label across the evaluated systems. This process retains 3,687 consistency-passed rubrics, of which 2,600 remain distinguishable and form the final set of consensus-derived gold rubrics. Using this final rubric set, we obtain clearly differentiated rankings across 10 deep research systems, with item-level pass rates ranging from 58.58\% to 22.23\%. More broadly, because the pipeline removes human-expert execution from rubric generation and evaluation, it is naturally scalable for benchmark evaluation, automatic system comparison, and future studies of evaluation-driven system improvement.

A Shared Subcircuit Lets LLMs Count Down Across Tasks
共享子电路使大型语言模型在任务间进行倒计时
Abstract
Writing a sentence of exactly twelve words; ending a DNA sequence at the right codon; formatting an ASCII table. These are all tasks that language models can do that requires tracking how many tokens remain before a target. In this work, we identify in Llama-3.1-70B-Instruct a general mechanism for performing these tasks: a "countdown subcircuit" that compares the current position to a goal length and estimates the time remaining until then. We first isolate a countdown subcircuit in a controlled setting, in which the model is tasked with writing a fixed-length sentence ending in a specified word. We then investigate the geometry of the representations used by the subcircuit, and find that the subcircuit uses an identical motif previously identified in a frontier LLM on a separate task, thus suggesting that this motif is shared across models. Finally, we use unsupervised probing on a natural language dataset to find a variety of other tasks where this subcircuit is used, including tasks where the goal length is inferred from context rather than explicitly stated. Our work suggests that reverse-engineering subcircuits allows us to understand how behaviors generalize from a single example to many different tasks and even models.

LakeQuest: A Three-Domain Benchmark for Grounded Question Answering across Data Lakes
LakeQuest:一个跨数据湖的基于真实场景的问题回答三领域基准
Abstract
While modern question answering (QA) systems excel on clean, schema-aligned corpora, real-world knowledge is rarely so neatly packaged. Answering questions over enterprise and scientific data lakes requires systems to navigate heterogeneous, weakly structured collections of tables, passages, and linked metadata. Current benchmarks abstract away this noisy discovery process, failing to evaluate end-to-end performance. To bridge this gap, we introduce LakeQuest, a human-validated benchmark of 9,846 QA pairs designed to evaluate the end-to-end retrieve-and-synthesize pipeline over realistic data lakes. LakeQuest spans three diverse domains (AI/ML metadata, retail banking, and multimodal biomedical drug information) and pairs every question with exact, modality-aware evidence pointers. By isolating source discovery from cross-modal synthesis, LakeQuest exposes critical failure modes in modern QA systems. Our baseline evaluations, including standard Retrieval-Augmented Generation (RAG) and agentic tool-use methods, reveal that high-quality retrieval does not guarantee correct reasoning. Systems consistently struggle with relation chaining in metadata graphs, policy grounding in bank ledgers, and joint tabular QA in biomedical contexts, highlighting the need for robust discovery and faithful cross-file composition mechanisms in future agentic QA systems.

QUBO-Optimized Evidence Selection for Retrieval-Augmented Question Answering with Unconventional Solvers
基于QUBO优化的证据选择用于增强检索的问答系统与非常规求解器
Abstract
Retrieval-augmented question answering depends on selecting evidence passages that jointly support answer generation. However, many RAG pipelines rely on top-\(k\) ranking, where passages are selected mainly by individual relevance scores, even though multi-hop questions often require complementary evidence satisfying multiple information requirements. Recent LLM-based selectors address this by treating retrieval as set selection, but using an LLM for this intermediate stage can be costly and difficult to scale. In this work, we formulate evidence selection as a Quadratic Unconstrained Binary Optimization (QUBO) problem. Given a question, candidate passages, and decomposed information requirements, our method constructs an energy function that balances relevance, requirement coverage, support strength, redundancy, complementarity, and compactness. Low-energy solutions correspond to compact evidence subsets that cover the needed requirements while avoiding unnecessary or repetitive context. The selected passages are then passed to a downstream language model for answer generation, separating combinatorial evidence selection from semantic answer generation. We evaluate the proposed QUBO selector on HotpotQA and compare it with LLM-based set selectors and non-LLM baselines including BM25, relevance top-\(k\), maximal marginal relevance, hybrid lexical--semantic ranking, greedy coverage, and random selection. The QUBO selector achieves competitive exact-match and token-F1 performance relative to LLM-based selectors while providing a solver-compatible formulation for structured evidence selection. These results suggest that multi-hop evidence selection can be cast as discrete optimization, opening a path toward RAG pipelines where LLMs are reserved for semantic processing and answer generation, while context selection is handled by Ising/QUBO-compatible solvers.

增强检索的问答系统依赖于选择共同支持答案生成的证据段落。然而,许多RAG(检索增强生成)流程依赖于前k名排名,其中段落主要通过单个相关性评分进行选择,尽管多跳问题通常需要满足多个信息需求的互补证据。最近的基于大型语言模型(LLM)的选择器通过将检索视为集合选择来解决这个问题,但在这个中间阶段使用LLM可能成本高昂且难以扩展。在本研究中,我们将证据选择形式化为一个二次无约束二进制优化(QUBO)问题。给定一个问题、候选段落和分解的信息需求,我们的方法构建了一个能量函数,平衡相关性、需求覆盖、支持强度、冗余、互补性和紧凑性。低能量解对应于覆盖所需需求的紧凑证据子集,同时避免不必要或重复的上下文。然后,将选定的段落传递给下游语言模型进行答案生成,从而将组合证据选择与语义答案生成分开。我们在HotpotQA上评估了所提出的QUBO选择器,并将其与基于LLM的集合选择器和包括BM25、相关性前k名、最大边际相关性、混合词汇-语义排名、贪婪覆盖和随机选择在内的非LLM基线进行比较。QUBO选择器在精确匹配和token-F1性能方面相对于基于LLM的选择器表现出竞争力,同时为结构化证据选择提供了求解器兼容的形式。这些结果表明,多跳证据选择可以被视为离散优化,为RAG流程开辟了一条道路,在该流程中,LLM被保留用于语义处理和答案生成,而上下文选择则由Ising/QUBO兼容的求解器处理。

Evaluating Health Misinformation in Low-Resource Languages: Integrating Small Language Models with a Culturally-Sensitive Responsible NLP Framework (Bangla as a Case Study)
评估低资源语言中的健康错误信息:将小型语言模型与文化敏感的负责任自然语言处理框架相结合(以孟加拉语为案例研究)
Abstract
Artificial Intelligence (AI) technologies, while serving as a foundational enabler for modern social media and digital health services, exert a bivalent effect by simultaneously acting as a combatant against and a spread vector for misinformation. A prevalent challenge in mitigating this issue arises in non-English contexts and low socioeconomic classes, where limited data hinders the training of AI models for effective detection. Consequently, culturally and linguistically diverse (CALD) communities struggle to access trustworthy health information through AI-driven tools. Current AI tools underperform due to a lack of training data and are largely unable to consider language nuances and traditions in non-English contexts. This research addresses these gaps by proposing a CALD-friendly AI-based health misinformation detector and providing a dashboard for medical professionals to analyse this misinformation, a critical step toward mitigating a growing concern among CALD populations. To this end, we conduct a series of experiments using a Bangla-translated health misinformation dataset to evaluate the performance of various Small Language Models (SLMs). SLMs are particularly relevant in this context given the frequent underperformance of Large Language Models (LLMs), which often stems from insufficient domain-specific knowledge and the prohibitive costs of resource-intensive fine-tuning. The results demonstrate that Phi-4 is the superior model, achieving an ideal balance between precision and recall in claim extraction. Then, to mitigate the limitations of SLMs, we design and test a novel health misinformation detection framework grounded in Responsible Natural Language Processing (NLP), which incorporates cultural sensitivity, potential for harm, and communication quality, thereby providing a holistic lens for evaluating misinformation in low-resource languages.

Policy-Conditioned Constrained Decoding for Column-Level Access Control in Text-to-SQL
基于策略约束解码的文本到SQL列级访问控制
Abstract
Text-to-SQL is increasingly deployed across trust boundaries between data providers and users. Such deployment must balance three competing requirements: policy compliance, answer coverage, and bounded cost. Existing approaches typically decide refusal based on which columns a query mentions and enforce it stochastically. Whether a query is compliant, however, depends not only on which columns appear but on how they are used, and stochastic enforcement cannot deterministically rule out violations. We formalize this requirement as a column-use policy over semantic use: output, filter condition, and aggregation argument. We integrate the policy by aligning each role with grammar productions tracked by the decoder. The resulting system, PCC-SQL, applies a per-token logits mask that deterministically eliminates single-query column-use violations on the supported SQL fragment in a single decoding pass. Across three benchmarks and three open-source models, PCC-SQL achieves 0% Leakage Rate and Coverage up to 88.7% on Spider-CU, while staying within +10% tokens of direct prompting. We additionally assess semantic alignment with execution accuracy.

文本到SQL的应用越来越多地跨越数据提供者与用户之间的信任边界。这种部署必须平衡三个相互竞争的要求:政策合规性、答案覆盖率和成本限制。现有的方法通常根据查询提及的列来决定拒绝,并以随机方式执行。然而,查询是否合规不仅取决于出现的列,还取决于这些列的使用方式,而随机执行无法确定性地排除违规情况。我们将这一要求形式化为基于语义使用的列使用政策:输出、过滤条件和聚合参数。我们通过将每个角色与解码器跟踪的语法生成式对齐来整合该政策。最终系统PCC-SQL应用了每个标记的logits掩码,确定性地消除了在单次解码过程中对支持的SQL片段的单查询列使用违规。在三个基准测试和三个开源模型中,PCC-SQL实现了0%的泄漏率和高达88.7%的Spider-CU覆盖率,同时令直接提示的标记数保持在+10%以内。我们还评估了与执行准确性的语义对齐。

Cancer-related discussions on social media provide an important space for information exchange and peer support, but also facilitate the spread of misinformation that may influence prevention, screening, and treatment decisions. Existing research on cancer misinformation often relies on narrow definitions, small-scale datasets, or binary labeling frameworks. We introduce a multi-dimensional taxonomy for characterizing cancer misinformation in Reddit discussions of breast, lung, colon, and prostate cancer. The taxonomy captures seven dimensions, including misinformation presence, information type, risk level, stance, and topical focus. Using expert-annotated data, we evaluate multiple large language models (LLMs) for scalable misinformation annotation and analyze cancer misinformation across Reddit communities. Our results show that cancer-related misinformation constitutes approximately 6\% of Reddit cancer discussions, with substantial variation across communities and misinformation topics. Few-shot prompting substantially improves classification performance, particularly for nuanced taxonomy dimensions. We additionally identify recurring misinformation narratives centered on unsupported treatments, distrust of conventional medicine, and misleading claims about diagnosis and screening. Our taxonomy, dataset, and findings provide a foundation for multi-dimensional modeling of online cancer misinformation.

社交媒体上与癌症相关的讨论为信息交流和同伴支持提供了重要空间,但也促进了可能影响预防、筛查和治疗决策的误信息传播。现有关于癌症误信息的研究往往依赖于狭隘的定义、小规模的数据集或二元标记框架。我们提出了一种多维分类法,用于描述Reddit上关于乳腺癌、肺癌、结肠癌和前列腺癌的讨论中的癌症误信息。该分类法捕捉了七个维度,包括误信息存在、信息类型、风险水平、立场和主题焦点。通过使用专家标注的数据,我们评估了多种大型语言模型(LLMs)在可扩展的误信息标注中的表现,并分析了Reddit社区中的癌症误信息。我们的结果显示,癌症相关的误信息约占Reddit癌症讨论的6%,在不同社区和误信息主题之间存在显著差异。少量示例提示显著提高了分类性能,尤其是在细微的分类维度上。我们还识别出围绕不支持的治疗、对传统医学的不信任以及关于诊断和筛查的误导性声明的反复出现的误信息叙事。我们的分类法、数据集和研究结果为在线癌症误信息的多维建模提供了基础。

Ring-Zero: Scaling Zero RL to a Trillion Parameters for Emergent Reasoning
Ring-Zero:将零强化学习扩展至万亿参数以实现新兴推理
Abstract
Reinforcement learning with verifiable rewards without human-annotated data, often referred to as zero RL, has emerged as a powerful paradigm for eliciting chain-of-thought reasoning. However, due to computational constraints, existing studies are largely restricted to small models, leaving the training dynamics and emergent capabilities at a large scale unexplored. To meaningfully explore this frontier, we aim to elicit high-quality reasoning behaviors from the model. However, we find that naive scaling often suffers from poor readability, token redundancy, and a lack of adaptive reasoning depth. To address these challenges, we present a stable and efficient training pipeline, incorporating algorithmic and system optimizations such as clipped importance sampling, training-inference ratio correction, and mixed-precision control. Our experiments offer three key findings that validate the "bitter lesson" of scaling: (1) scaling to 1T parameters significantly enhances sample efficiency and performance ceilings; (2) the training process progresses sequentially through an initial discovery phase followed by a sharpening phase; and (3) the model spontaneously develops advanced cognitive behaviors, including anthropomorphism, structured formatting, self-verification, parallel reasoning, and context anxiety, rendering hand-crafted heuristics redundant. Evaluated on seven mathematical benchmarks, Ring-2.5-1T-Zero achieves competitive performance. Additionally, to assess CoT quality beyond final-answer correctness, we propose a structured evaluation framework across three dimensions: comprehensibility, reproducibility, and efficiency, where our model demonstrates clear advantages in producing structured and concise reasoning traces. By sharing our observed emergent phenomena, we hope to provide the community with deeper insights into scaling behaviors, particularly at the 1-trillion scale.

无须人工标注数据的可验证奖励强化学习,通常被称为零强化学习(zero RL),已成为引发连锁思维推理的强大范式。然而,由于计算限制,现有研究主要局限于小型模型,尚未探索大规模下的训练动态和新兴能力。为了有意义地探索这一前沿,我们旨在从模型中引发高质量的推理行为。然而,我们发现,简单的扩展往往会遭遇可读性差、标记冗余和缺乏自适应推理深度等问题。为了解决这些挑战,我们提出了一种稳定高效的训练流程,结合了算法和系统优化,如剪切重要性采样(clipped importance sampling)、训练-推理比率校正和混合精度控制。我们的实验提供了三个关键发现,验证了扩展的“苦涩教训”: (1) 扩展至1万亿参数显著提高了样本效率和性能上限; (2) 训练过程依次经历初始发现阶段和后续的锐化阶段; (3) 模型自发发展出高级认知行为,包括拟人化、结构化格式、自我验证、并行推理和上下文焦虑,使得手工设计的启发式方法变得多余。在七个数学基准上评估时,Ring-2.5-1T-Zero表现出竞争力。此外,为了评估连锁推理(CoT)质量超越最终答案的正确性,我们提出了一个跨越三个维度的结构化评估框架:可理解性、可重复性和效率,在这些维度上,我们的模型在生成结构化和简洁的推理痕迹方面表现出明显优势。通过分享我们观察到的新兴现象,我们希望为社区提供对扩展行为的更深入见解,特别是在万亿规模下。

WikiSTAR: A System for Shedding Light on the Hidden History of Scientific Wikipedia Articles
WikiSTAR:揭示科学维基百科文章隐藏历史的系统
Abstract
Wikipedia plays a key role in shaping public understanding of science, and its openly accessible revision history is a unique record of how scientific knowledge evolves over time. Yet scientifically meaningful revisions are obscured by the sheer volume of routine edits, leaving each article's scientific history hidden. We present WikiSTAR (Scientific Tracking of Article Revisions), an interactive system for exploring scientifically meaningful changes across an article's revision history. Using an LLM classifier with an expert-designed multi-label taxonomy, WikiSTAR first tags edit types such as the addition of technical terms, new research findings, and changes in scientific narrative. Then, through interactive views, an article's full revision history can be traced at any granularity - from aggregate trends that reveal when and in which sections scientific content was added or refined, down to individual edits - showing how scientific knowledge develops at a scale previously impossible. In a user study, experts from three domains found that WikiSTAR surfaced new patterns and research questions and enabled previously impractical analyses. We release our system, code and a human-annotated benchmark.

Language Identification with Succinct Machine-Independent Traces
使用简洁的机器无关痕迹进行语言识别
Abstract
Motivated by the power of large language models, there has been renewed interest in the Gold-Angluin model of language identification in the limit, with an eye toward variants of the model that might overcome the negative results for its original formulation. Recent papers on this question have proposed looking at computational traces and annotations of training strings as a source of additional power for a learner, reflecting empirical regularities such as the way that commented source code is easier to learn from than arbitrary source code, and text annotated with algorithmically generated chain-of-thought tokens can be easier to learn from than the raw text itself. This recent work has shown positive results for language identification in the presence of such computational traces, but the traces in these positive results come from explicit automata-theoretic machine models that generate the language, where the underlying vocabulary of tokens for the traces is very large. In this paper, we address two fundamental issues left open by this line of work: can we achieve positive results with traces that use only a small alphabet, and can we define traces directly from the language itself, without requiring an underlying machine model that generates it? We establish positive results for both of these questions: for an arbitrary collection of languages, we show how to define computational traces that enable identification in the limit, using an alphabet of tokens that is linear in the size of the alphabet that the languages are defined over, and independent of any other properties of the languages.

受大型语言模型的启发,语言识别的Gold-Angluin模型在极限情况下重新引起了关注,尤其是针对可能克服其原始表述负面结果的模型变体。最近关于这个问题的论文提出,计算痕迹和训练字符串的注释可以作为学习者额外能力的来源,反映出经验规律,例如注释的源代码比任意源代码更易于学习,带有算法生成的思维链标记的文本比原始文本更易于学习。这项最新工作在存在这些计算痕迹的情况下显示了语言识别的积极结果,但这些积极结果中的痕迹来自于显式的自动机理论机器模型,这些模型生成的语言的基础标记词汇量非常庞大。本文解决了这一系列研究所留下的两个基本问题:我们能否仅使用小字母表的痕迹获得积极结果,以及我们能否直接从语言本身定义痕迹,而不需要生成它的基础机器模型?我们为这两个问题建立了积极结果:对于任意语言集合,我们展示了如何定义计算痕迹,使其能够在极限情况下进行识别,使用的标记字母表大小与语言定义所用字母表的大小成线性关系,并且与语言的其他属性无关。

Translation as a Computationally Efficient Bridge: Feasibility of English BERT for Low-Resource Languages
翻译作为一种计算高效的桥梁:英语 BERT 在低资源语言中的可行性
Abstract
BERT models have revolutionised Natural Language Processing (NLP) through their ability to process unstructured text across diverse domains. However, developing high-quality BERT models for non-English languages remains challenging due to limited annotated data and high computational demands. Translating non-English data into English and fine-tuning existing English BERT models offers a resource-efficient alternative, yet few studies have structurally compared translation-based fine-tuning with native-language BERT performance across tasks and languages. This study provides such a comparison, evaluating the feasibility of translation-based fine-tuning across six NLP tasks: Sentiment Analysis, Hate Speech Detection, Question Answering, Named Entity Recognition, Part-of-Speech Tagging, and Natural Language Inference, using datasets translated from Bulgarian, Chinese, Dutch, Italian, and Russian. Across all settings, the translation-based approach was comparable or superior in 53.3 percent of cases. Gains were most frequent in Question Answering, Part-of-Speech Tagging, and Natural Language Inference, while performance declines were common in Named Entity Recognition and Hate Speech Detection. The results show that translation-based fine-tuning is most effective for tasks relying on syntactic or structural patterns and for languages typologically close to English, such as Dutch, but less effective for token-level or culturally nuanced tasks, particularly in Chinese. Overall, this study demonstrates that translation-based fine-tuning offers a scalable, resource-efficient, and empirically validated path for extending NLP to low-resource languages while advancing linguistic inclusivity and sustainability in artificial intelligence.

KnowAct-GUIClaw: Know Deeply, Act Perfectly, Personal GUI Assistant with Self-Evolving Memory and Skill
KnowAct-GUIClaw:深入了解,完美行动,具有自我进化记忆和技能的个人图形用户界面助手
Abstract
OpenClaw has emerged as a leading agent framework for complex task automation, yet it faces insufficient cross-platform GUI interaction support and a well-built self-evolution mechanism. These flaws limit its adaptation to diverse device ecosystems and prevent performance improvements through continuous learning from execution experience. To resolve these issues, we propose the Know Deeply, Act Perfectly paradigm for personal assistants, which holds that accumulated user interaction and task-running experience directly improve execution accuracy and efficiency, unifying cognitive comprehension and operational execution. Based on this paradigm, we introduce KnowAct-GUIClaw, a novel Know-Route-Act-Reflect framework designed to address OpenClaw's GUI manipulation deficits and break through its cross-platform and recursive self-improvement constraints. First, the host agent leverages accumulated interaction experience and task-relevant knowledge for long-horizon task decomposition and allocation (Know). Second, a pluggable GUI subagent with an experience-attributable memory system (Know) and self-evolving skill library (Act), enabling seamless cross-platform migration and fast-path integration. Especially, this framework continuously stores user profiles and feedback to improve the accuracy of task decomposition and tool calls. Extensive experiments across Android, iOS, HarmonyOS and Windows show that KnowAct-GUIClaw achieves superior efficiency, accuracy and cross-platform adaptability. Especially, the GUIClaw with open-source Kimi-2.6 models achieves the best performance (64.1%) on the long-horizon MobileWorld benchmark, beating all agentical frameworks and closed-source agentical models, e.g., Seed-2.0-Pro and GPT-5.5. Additionally, the knowledgeable memory and execution skills supported by our framework are transferable across diverse base models, improving by 8.5% with Kimi-2.6.

Can Induced Emotion Bias LLM Behaviors in Sequential Decision Making?
诱发情绪能否影响大语言模型在顺序决策中的行为?
Abstract
As Large Language Models (LLMs) are increasingly deployed as autonomous agents in high-stakes domains, understanding contextual factors that may modulate their decision-making becomes critical. While LLMs are trained to perceive and resonate with users' emotions, it remains unclear whether induced emotion can influence their sequential decision-making. We investigate this question using the Iowa Gambling Task (IGT), a classic psychological paradigm for studying decision-making under uncertainty, combined with an imagination-based emotion induction procedure. We first validate the feasibility of this paradigm by confirming that LLMs can sense strong, distinguishable emotions from context and that LLM agents can learn from sequential interactions in a human-like pace. With the validated setup, we find that, different from humans, induced emotion does not significantly bias the decision dynamics of LLM agents on average. However, the effects of anger are conditioned: inducing anger makes LLM agents less sensitive to penalties for bad decisions, and in early stages of the game, anger can lower exploration, locking decisions into a few choices early. These findings reveal the subtle yet distinct effects of induced emotion on LLM decision-making compared to human behavior, and provide a tool for future research on affective modulation of LLM agents.

随着大语言模型(LLMs)越来越多地作为自主代理在高风险领域中应用,理解可能调节其决策的上下文因素变得至关重要。尽管LLMs经过训练能够感知并共鸣用户的情绪,但诱发的情绪是否能影响其顺序决策仍不清楚。我们使用爱荷华赌博任务(Iowa Gambling Task, IGT)这一经典心理学范式来研究不确定性下的决策,并结合基于想象的情绪诱导程序来探讨这一问题。我们首先通过确认LLMs能够从上下文中感知强烈且可区分的情绪,并且LLM代理能够以类似人类的节奏从顺序交互中学习,验证了这一范式的可行性。在经过验证的设置中,我们发现,与人类不同,诱发的情绪对LLM代理的决策动态在平均水平上并没有显著偏向。然而,愤怒的影响是有条件的:诱发愤怒使LLM代理对糟糕决策的惩罚敏感性降低,并且在游戏的早期阶段,愤怒可以降低探索行为,使决策早期锁定在少数选择上。这些发现揭示了诱发情绪对LLM决策的微妙但明显的影响,与人类行为相比,并为未来关于LLM代理情感调节的研究提供了工具。

Segregate, Refine, Integrate: Decomposing Multimodal Fusion for Sentiment Analysis
分离、精炼、整合:情感分析中的多模态融合分解
Abstract
Multimodal fusion must simultaneously refine modality-specific signals and model cross-modal interactions; two competing objectives typically entangled within the same operation. We propose \textbf{SeRIn} (\textbf{Se}gregate, \textbf{R}efine, \textbf{In}tegrate), a multimodal LM fusion scheme that enforces this separation as an architectural prior. Modality-specific representations evolve along isolated pathways, each refined against its respective encoder context, while a dedicated cross-modal pathway accumulates their joint evolution without contaminating unimodal streams. Full cross-modal interaction is deferred to a final prediction step - ablations confirm that structured interactions, not added capacity, drive the gains; gate analysis under visual corruption reveals emergent modality reweighting without explicit supervision. SeRIn achieves state-of-the-art results on CH-SIMS and CMU-MOSEI, improving all metrics on both benchmarks.

From Critic to Confidence: PPO for Language-Based Quantitative Prediction with Confidence Estimation
从批评到信心:基于语言的定量预测与信心估计的 PPO 方法
Abstract
LLMs can perform language-based quantitative prediction from unstructured inputs, but remain susceptible to hallucinations and overconfident errors, making it critical to know not only what a model predicts, but when its predictions can be trusted. We introduce CARE-PPO, a reinforcement learning framework that establishes a connection between loss prediction for uncertainty estimation and actor-critic PPO fine-tuning, enabling joint learning of accurate numerical estimates and reliable confidence signals in language-based quantitative prediction. CARE-PPO uses a Confidence-Aligned Reward for Estimation, defined as a function of prediction error, to provide dense error-aware feedback to the actor while inducing the critic to learn a value function aligned with prediction quality. During inference, we repurpose the critic as a confidence estimator. Across two real-world tasks in healthcare and finance and two Qwen-3 model scales (4B and 8B), CARE-PPO achieves strong quantitative prediction performance, while producing significantly better-aligned confidence estimates through the critic than logit-based and verbalized baselines. These gains persist under realistic out-of-distribution settings across domains, spanning linguistic and domain shifts. Finally, CARE-PPO reduces task-specific overfitting on general instruction-following prompts, consistent with the broader generalization advantages of RL fine-tuning over supervised approaches.

Less Experts, Faster Decoding: Cost-Aware Speculative Decoding for Mixture-of-Experts
更少的专家,更快的解码:面向成本的投机解码在专家混合模型中的应用
Abstract
Sparse Mixture-of-Experts (MoE) models have become an important approach for scaling Large Language Models (LLMs), but their inference efficiency depends strongly on expert activation patterns. Speculative decoding (SD) accelerates autoregressive generation by verifying multiple draft tokens in parallel, yet existing draft selection strategies primarily optimize acceptance likelihood. In large-scale MoE models, however, selecting draft tokens also determines the union of experts activated during verification. We observe that confidence-driven SD can introduce \textit{expert scattering}: high-probability draft tokens may route to disjoint experts, increasing expert-weight memory traffic and reducing the speedup from speculation. Motivated by this observation, we revisit draft-tree selection under the non-uniform memory-cost structure of MoE inference. We propose \textsc{EcoSpec}, a cost-aware speculative decoding framework that incorporates predicted marginal expert activation cost into draft selection. With a lightweight expert predictor and a dynamic expert buffer, \textsc{EcoSpec} favors draft paths that preserve high acceptance likelihood while reusing experts already covered by the current verification set, without modifying the target-model verification rule. We evaluate \textsc{EcoSpec} on three large-scale MoE models, including DeepSeek-V3.1 (671B), Qwen3-235B-A22B, and GPT-OSS-120B, across reasoning, coding, question-answering, and dialogue benchmarks. \textsc{EcoSpec} consistently reduces active expert footprints and improves end-to-end decoding speed, achieving up to $1.62\times$ speedup. These results show that accounting for expert activation cost is important for efficient speculative decoding in large-scale MoE models.

稀疏的专家混合模型(Mixture-of-Experts, MoE)已成为扩展大型语言模型(Large Language Models, LLMs)的一种重要方法,但其推理效率在很大程度上依赖于专家激活模式。投机解码(Speculative Decoding, SD)通过并行验证多个草稿标记来加速自回归生成,然而现有的草稿选择策略主要优化接受概率。然而,在大规模的 MoE 模型中,选择草稿标记也决定了在验证过程中激活的专家集合。我们观察到,基于置信度的 SD 可能引入“专家分散”(expert scattering):高概率的草稿标记可能会路由到不相交的专家,从而增加专家权重的内存流量,并降低投机带来的加速效果。基于这一观察,我们重新审视了在 MoE 推理的非均匀内存成本结构下的草稿树选择。我们提出了 extsc{EcoSpec},一种成本感知的投机解码框架,该框架在草稿选择中结合了预测的边际专家激活成本。通过轻量级的专家预测器和动态专家缓冲区, extsc{EcoSpec} 优先选择那些在保持高接受概率的同时,重用当前验证集已覆盖的专家的草稿路径,而无需修改目标模型的验证规则。我们在三个大规模 MoE 模型上评估了 extsc{EcoSpec},包括 DeepSeek-V3.1(671B)、Qwen3-235B-A22B 和 GPT-OSS-120B,涵盖推理、编码、问答和对话基准。结果表明, extsc{EcoSpec} 一致性地减少了活跃专家的占用,并提高了端到端解码速度,达到了最高 $1.62 imes$ 的加速。这些结果表明,考虑专家激活成本对于大规模 MoE 模型中的高效投机解码至关重要。

Epistemic Stance Flexibility Probing: Measuring Prompt-Conditioned Register Shift in Large Language Models
认知立场灵活性探测:测量大型语言模型中提示条件下的语域转换
Abstract
A language model may be asked either what experts believe about a contested claim or what it believes about the claim itself. A trustworthy conversational agent should distinguish these two requests and respond in different epistemic registers: neutral attribution in the first case and stance expression in the second. Whether such a shift occurs-and whether it occurs coherently-is not directly assessed by existing benchmarks for accuracy, instruction following, or safety. We introduce ESFP, a behavioral benchmark that treats the contrast between externally attributed and self-attributed prompts as the fundamental unit of measurement. ESFP consists of 104 carefully controlled items spanning six epistemic categories and five phrasing templates, and evaluates model responses along four complementary dimensions: lexical self-attribution, representation-level responsiveness to role framing, sentence-level stance content density assessed by an LLM judge panel, and cross-condition stance consistency. Evaluating eight frontier models from five vendors, we find that epistemic flexibility is largely orthogonal to general model capability: a 27B open-weight model matches the strongest proprietary systems, the flagship model of one family underperforms its lightweight counterpart, and reasoning-optimized models do not consistently exhibit higher flexibility. Stance content density provides the strongest signal, while surface-level lexical markers such as 'I think' can change substantially without corresponding changes in expressed stance. We provide item-level bootstrap confidence intervals, weight-sensitivity analyses, and an explicit discussion of the interpretation limits of the composite score. ESFP measures a model's propensity to adapt its epistemic stance under changing attribution conditions, rather than a general competence measure.

The One-Word Census: Answer-Choice Conformity Across 44 Language Models
一词普查:44种语言模型的答案选择一致性
Abstract
When a language model must pick one answer from a large space of equally valid options, which does it pick -- and how often is it the same answer every other model picks? Asked to "pick a word -- any word," 44 models chose "serendipity" 41% of the time. We characterize this convergence with a deliberately minimal instrument: 31 single-turn prompts, each naming a category with many valid one-word answers ("Name a tree."), asked four times per model with no system prompt. Analysis is exact-match on normalized tokens -- no embeddings, no judge -- at about a dollar per model. That models converge is well documented; our contribution is the instrument itself -- the One-Word Census -- and what it reveals about the structure of the convergence. We score each model by answer-choice surprisal: the average $-\log2$ probability of its answers under the pooled answers of all other models, leave-one-out. Convergence is extreme -- in 7 of 31 categories one answer takes over 80% of all answers -- yet conformity varies more than fourfold across models, and the variation is structured. Persona- and community-tuned models are the most divergent; the newest mainline flagships are the most conformist, producing almost no answer no other model gave. Within four lineages (Claude, GPT, Qwen, Grok) conformity rises with each generation -- but reverses for the latest flagship Claude and GPT models, a possible early signal of repositioning at the top tier. Rankings are robust to roster composition (leave-one-family-out rho = 0.985). Against human category-production norms, the field is more concentrated than people in 18 of 20 shared categories. All prompts, transcripts, and code are public.

Language models encode substantial factual knowledge in their parameters, which can lead to unreliable behavior when this knowledge is outdated, incomplete, or misaligned with the provided context. In this work, we study whether modifying the pretraining signal can systematically shift models away from parametric recall and toward evidence-grounded reasoning. We introduce Knowledge--''Less'' Language Models (KLLMs), a fundamentally different epistemic training paradigm for LLMs, which are pretrained on corpora in which named entities are anonymized, thereby removing a primary channel for entity-linked factual supervision. This intervention substantially reduces closed-book factual recall, while often improving performance on tasks where relevant information is provided as context. Across multiple model scales, KLLMs consistently outperform matched baselines on contextual question answering, fact verification, and hallucination detection benchmarks. Crucially, in retrieval-grounded settings with imperfect evidence, KLLMs show improved robustness and achieve up to 20--25\% relative gains over standard language models. They further exhibit better calibration, with improved ECE, Brier score, and AUROC, as well as more reliable abstention behavior. Our results demonstrate that suppressing entity-linked supervision during pretraining induces a shift in epistemic behavior: KLLMs rely less on parametric knowledge and more on external evidence, leading to improved reliability under realistic conditions. This suggests that pretraining-time control over knowledge acquisition can complement retrieval-augmented and tool-based systems by providing a more evidence-sensitive base model.

语言模型在其参数中编码了大量的事实知识,这可能导致在这些知识过时、不完整或与提供的上下文不一致时出现不可靠的行为。在本研究中,我们探讨了修改预训练信号是否可以系统性地使模型远离参数记忆,转向基于证据的推理。我们提出了知识“无”语言模型(Knowledge--''Less'' Language Models, KLLMs),这是一种根本不同的LLM(大语言模型)训练范式,其在命名实体被匿名化的语料库上进行预训练,从而消除了与实体相关的事实监督的主要渠道。这一干预显著降低了闭卷事实记忆,同时在相关信息作为上下文提供的任务上通常提高了性能。在多个模型规模上,KLLMs在上下文问答、事实验证和幻觉检测基准测试中始终优于匹配的基线模型。至关重要的是,在证据不完美的检索基础设置中,KLLMs表现出更强的鲁棒性,相较于标准语言模型实现了高达20-25%的相对增益。它们还表现出更好的校准,改进了ECE(期望校准误差)、Brier分数和AUROC(曲线下面积),以及更可靠的弃权行为。我们的结果表明,在预训练期间抑制与实体相关的监督会导致认知行为的转变:KLLMs更少依赖参数知识,而更多依赖外部证据,从而在现实条件下提高了可靠性。这表明,预训练期间对知识获取的控制可以通过提供更具证据敏感性的基础模型来补充检索增强和基于工具的系统。

Can LLMs Write Reliable Rubrics? A Meta-Evaluation for Experiment Reproduction
大型语言模型能否编写可靠的评分标准?实验重现的元评估
Abstract
Rubric-based evaluation is a promising approach for assessing open-ended outputs from LLM-based research agents, particularly in paper reproduction, where direct paper-to-repository comparison is prone to hallucination. However, constructing paper-specific rubrics requires substantial expert effort, limiting the scalability of benchmarks such as PaperBench. In this work, we present, to our knowledge, the first systematic meta-evaluation of LLM-generated rubrics for paper reproduction. We reformulate rubrics into a checklist-style format and evaluate four generation settings across two backbone models. We meta-evaluate generated rubrics intrinsically by semantic similarity and extrinsically by score alignment with ground-truth rubrics. Our results show that the augmented settings substantially improves downstream evaluation alignment, with the strongest setting approaching the human baseline, while intrinsic gains are more modest. Further analyses reveal that LLM-generated rubrics are often overly fine-grained, biased toward high scores, and less adaptive to paper domains, highlighting both the affordances and limitations.

基于评分标准的评估是一种有前景的方法,用于评估来自大型语言模型(LLM)研究代理的开放式输出,特别是在论文重现中,直接的论文与仓库比较容易出现幻觉。然而,构建特定论文的评分标准需要大量专家的努力,这限制了诸如PaperBench等基准的可扩展性。在本研究中,我们首次系统性地对LLM生成的评分标准进行元评估,专注于论文重现。我们将评分标准重新格式化为检查表样式,并在两个基础模型上评估四种生成设置。我们通过语义相似性对生成的评分标准进行内在元评估,并通过与真实评分标准的分数对齐进行外在评估。我们的结果表明,增强设置显著改善了下游评估的对齐,最强的设置接近人类基准,而内在收益则相对温和。进一步分析显示,LLM生成的评分标准往往过于细化,偏向高分,并且对论文领域的适应性较差,突显了其优点和局限性。

Evaluating Large Language Models on Misconceptions in Multi-Turn Medical Conversations
评估大型语言模型在多轮医疗对话中的误解表现
Abstract
Patients seeking medical information often ask questions that embed incorrect assumptions or misconceptions. In such cases, safe medical communication requires not only answering the question, but identifying and correcting the underlying false belief. These interactions naturally unfold over multiple turns, a pattern now mirrored in interactions with LLMs. Yet current evaluation frameworks do not capture model behavior in these settings, where misconceptions can emerge, persist, or evolve over the course of a conversation. Whether LLMs can reliably correct such misconceptions over time remains largely unexamined. To study this, we introduce ThReadMed-QA, a multi-turn medical dialogue dataset of 2,437 patient-physician conversation threads comprising 8,204 question-answer pairs, derived from real patient interactions on AskDocs. This dataset enables systematic evaluation of whether models can detect and correct misconceptions under a multi-turn context. We evaluate five LLMs using a rubric-based LLM-as-a-Judge framework that scores responses based on their ability to identify and correct misconceptions. Our experiments reveal a consistent pattern: even frontier models that can address misconceptions in a single interaction degrade substantially over subsequent turns. GPT-5 and Claude-Haiku correct these false presuppositions around 85% on initial questions but drop to roughly 50% within two follow-ups. An oracle analysis replacing prior model outputs with physician responses shows that much of the degradation is driven by error propagation, while performance remains imperfect even under correct context. Even when models tend to correct misconceptions initially, their performance degrades substantially over later turns, leading to inconsistent and potentially unsafe guidance in patient-facing settings and highlighting the need for evaluation frameworks that capture multi-turn behavior.

寻求医疗信息的患者常常提出嵌含错误假设或误解的问题。在这种情况下,安全的医疗沟通不仅需要回答问题,还需要识别和纠正潜在的错误信念。这些互动自然会在多个回合中展开,这一模式现在也体现在与大型语言模型(LLMs)的互动中。然而,当前的评估框架并未捕捉到模型在这些场景中的行为,在这些场景中,误解可能会在对话过程中出现、持续或演变。LLMs是否能够可靠地随时间纠正这些误解仍然在很大程度上未被研究。为此,我们引入了ThReadMed-QA,这是一个包含2,437个患者-医生对话线程的多轮医疗对话数据集,包含8,204个问答对,来源于真实患者在AskDocs上的互动。该数据集使得系统评估模型在多轮上下文中是否能够检测和纠正误解成为可能。我们使用基于评分标准的LLM-as-a-Judge框架评估五个LLMs,该框架根据其识别和纠正误解的能力对响应进行评分。我们的实验揭示了一种一致的模式:即使是能够在单次互动中处理误解的前沿模型,在后续回合中也会显著退化。GPT-5和Claude-Haiku在初始问题上纠正这些错误假设的准确率约为85%,但在两次后续提问中降至约50%。用医生的回答替代先前模型输出的oracle分析表明,许多退化是由错误传播驱动的,而即使在正确的上下文中,性能仍然不完美。即使模型在最初倾向于纠正误解,其性能在后续回合中也会显著下降,导致在面向患者的环境中提供不一致且潜在不安全的指导,突显了需要评估框架以捕捉多轮行为的必要性。

LLM Judges Can Be Too Generous When There Is No Reference Answer
当没有参考答案时,LLM评判者可能过于宽容
Abstract
LLM judges are increasingly being used to evaluate open-ended model responses, often in no-reference settings where a ground-truth answer is unavailable. However, can they reliably assess in such evaluation setups? We explore this question in this paper through a two stage pipeline with a) calibration experiments that assess the judge model's knowledge of the task it is evaluating, and b) sensitivity experiments that assess how the judge model's performance is impacted by the presence and positioning of the reference answer in the prompt. Across experiments covering three languages, we show that the judge models we evaluated tend to over-credit incorrect answers in the absence of a reference answer, and adding reference answer information to the prompt flips the judge model's correct/incorrect decisions by as much as 85% in some experimental settings. Comparison with a subset of human annotations shows that these reference-driven changes generally align with human judgments. Our results emphasize the need for calibrating the LLM judges with a sample with reference-aware evaluation before using them in reference-free setups reliably, and our methodology provides a blueprint for researchers and practitioners in doing such calibration of LLM judges for other tasks.

LLM评判者越来越多地被用于评估开放式模型响应,通常是在没有参考答案的情况下进行评估。然而,在这样的评估设置中,它们能否可靠地进行评估?本文通过一个两阶段的流程探讨了这个问题:a) 校准实验评估评判模型对其评估任务的知识,b) 敏感性实验评估参考答案在提示中的存在和位置对评判模型表现的影响。在涵盖三种语言的实验中,我们发现所评估的评判模型在缺乏参考答案的情况下倾向于过度认可错误答案,而在某些实验设置中,将参考答案信息添加到提示中会使评判模型的正确/错误决策翻转多达85%。与一部分人类标注的比较显示,这些基于参考的变化通常与人类判断一致。我们的结果强调了在可靠地使用LLM评判者进行无参考设置之前,需要通过参考意识评估样本对其进行校准,我们的方法论为研究人员和从业者提供了在其他任务中进行LLM评判者校准的蓝图。

The Illusion of Robustness: Aggregate Accuracy Hides Prediction Flips under Task-Irrelevant Context
鲁棒性的幻觉:聚合准确性掩盖了任务无关上下文下的预测翻转
Abstract
As large language models (LLMs) grow more capable, they are increasingly deployed in context-rich settings where task inputs are often accompanied by long, partially irrelevant context. In a controlled setting, we find that state-of-the-art models often appear robust to task-irrelevant context at the aggregate level: prepending it to benchmark questions causes little change in overall accuracy. This aggregate stability, however, masks significant per-example instability. Even semantically meaningless pseudo-words, formed by randomly combining characters, can markedly shift model predictions on a small fraction of examples, degrading performance on some while improving it on others. This two-sided effect holds consistently across a wide range of models and datasets, yet the affected examples are largely model-specific. We further show that this instability is modulated by context type, context length, test-time compute, and model development stage. Together, our findings reveal context-induced tail risks concealed by aggregate accuracy, motivating per-example reliability evaluation of language models.

随着大型语言模型(LLMs)能力的不断增强,它们越来越多地被部署在上下文丰富的环境中,其中任务输入通常伴随着冗长的、部分无关的上下文。在一个受控环境中,我们发现最先进的模型在聚合层面上通常对任务无关的上下文表现出鲁棒性:将其添加到基准问题前面对整体准确性几乎没有影响。然而,这种聚合稳定性掩盖了显著的逐例不稳定性。即使是通过随机组合字符形成的语义上无意义的伪词,也能显著改变模型在少数示例上的预测,在某些情况下降低性能,而在其他情况下则提高性能。这种双面效应在广泛的模型和数据集上始终存在,但受影响的示例在很大程度上是模型特定的。我们进一步表明,这种不稳定性受到上下文类型、上下文长度、测试时计算能力和模型开发阶段的调节。总的来说,我们的发现揭示了聚合准确性掩盖的上下文引发的尾部风险,促使对语言模型进行逐例可靠性评估。

PalmClaw: A Native On-Device Agent Framework for Mobile Phones
PalmClaw:一种针对移动电话的本地设备代理框架
Abstract
Large Language Model (LLM) agents have moved beyond generating responses to executing multi-step tasks by calling tools, observing the results, and iteratively deciding the next action. Most agent systems run on desktops or servers, which support tool use and task automation. Mobile devices are also important agent environments because they are widely accessible and contain users' data, sensors, and daily-use applications. Existing mobile agents mainly operate smartphones through graphical user interface (GUI) actions such as tapping, swiping, and typing, which often form long, interface-dependent sequences, cannot directly access device capabilities, and make execution boundaries difficult to define. We present \textbf{PalmClaw}, an open-source agent framework that runs natively on mobile phones and manages the sessions, memory, skills, tools, and agent loop directly on the device. PalmClaw exposes device capabilities as device tools with explicit arguments, structured results, and clearly defined execution boundaries. This design enables agents to use mobile capabilities directly while keeping each action explicit and controlled. Experiments show an 11.5\% relative improvement in task success and a 94.9\% reduction in completion time over the strongest baseline, with lower setup burden and traces illustrating how execution boundaries are applied.

大型语言模型(LLM)代理已经超越了生成响应,能够通过调用工具、观察结果并迭代决定下一步行动来执行多步骤任务。大多数代理系统运行在桌面或服务器上,这些系统支持工具使用和任务自动化。移动设备同样是重要的代理环境,因为它们广泛可及,并包含用户数据、传感器和日常使用的应用程序。现有的移动代理主要通过图形用户界面(GUI)操作智能手机,例如点击、滑动和输入,这些操作通常形成长且依赖于界面的序列,无法直接访问设备功能,并且使执行边界难以定义。我们提出了 extbf{PalmClaw},一个开源代理框架,能够在移动电话上本地运行,并直接在设备上管理会话、内存、技能、工具和代理循环。PalmClaw将设备功能作为具有明确参数、结构化结果和清晰定义的执行边界的设备工具进行暴露。这种设计使得代理能够直接使用移动功能,同时保持每个动作的明确性和可控性。实验表明,相较于最强基线,任务成功率提高了11.5 ext%,完成时间减少了94.9 ext%,且设置负担更低,跟踪结果展示了执行边界的应用情况。代码可在 https://github.com/ModalityDance/PalmClaw 获取。
