Learning to Assist: Collaborative VLAs for Implicit Human-Robot Collaboration

学习辅助:隐式人机协作的协作视觉-语言-动作(VLA)模型
Xu, Leo, Li, Letian, Cuellar, Alex, Hagenow, Michael
Abstract
Human-robot collaboration (HRC) combines the complementary strengths of humans and robots to improve task efficiency. However, many existing collaborative systems rely on hand-engineered pipelines, limiting their scalability and flexibility for new tasks. In this work, we show that models trained end-to-end with imitation learning, specifically vision-language-action (VLA) models, can support collaborative manipulation, and characterize the key factors affecting their real-world performance. We evaluate two state-of-the-art models and identify a failure mode of action-chunking policies in implicit HRC, where demonstration action leakage (i.e., action chunks crossing latent task transitions) can cause premature assistive behavior. We find that this issue increases with longer execution horizons and occurs in real-world collaborative VLA systems, such as when a robot attempts to hand over a tool before the person is ready. We propose an inference-time steering method to mitigate these erroneous assistive actions while preserving policy performance. Finally, through a 16-participant user study on a long-horizon collaborative assembly task, we show that steering enables a longer execution horizon while mitigating premature assistance, leading to faster collaboration and fewer failures compared to a shorter-horizon policy.

人机协作(HRC)结合了人类和机器人互补的优势,以提高任务效率。然而,许多现有的协作系统依赖于手工设计的流程,这限制了它们在新任务中的可扩展性和灵活性。在本研究中,我们展示了通过模仿学习端到端训练的模型,特别是视觉-语言-动作(VLA)模型,可以支持协作操作,并表征影响其现实世界性能的关键因素。我们评估了两个最先进的模型,并识别出隐式人机协作中行动分块策略的一种失效模式,其中演示动作泄漏(即,动作块跨越潜在任务转变)可能导致过早的辅助行为。我们发现,这一问题在较长的执行时间范围内会增加,并且在现实世界的协作VLA系统中发生,例如当机器人试图在人员准备好之前递交工具时。我们提出了一种推理时引导方法,以减轻这些错误的辅助动作,同时保持策略性能。最后,通过对16名参与者进行的长时间协作组装任务的用户研究,我们展示了引导能够实现更长的执行时间范围,同时减轻过早的辅助行为,从而与短时间范围策略相比,促进更快的协作和更少的失败。

Action-Effect Memory Pretraining for Robot Manipulation

机器人操作的动作-效果记忆预训练
Zhou, Yijing, Liang, Qiwei, Zhuang, Sitong, Li, Jiaxi, Wang, Xianpeng, Cai, Boyang, Mo, Yunyang, Xu, Renjing
Abstract
We present AEM, an Action-Effect Memory pretraining framework for robot manipulation that learns compact temporal representations from vision-action history. Unlike prior robot representation pretraining methods that mainly focus on single-frame visual encoding, AEM targets the temporal nature of manipulation, where the current observation alone is often insufficient under partial observability. AEM models manipulation as an action-driven interaction process by interleaving visual and action features and applying masked modeling to recover missing content from incomplete histories, thereby learning action-conditioned state evolution. The Mamba-encoded output of the final vision token is used as a compact history representation, serving as the global context for decoding and downstream control. This design preserves a single-vector temporal bottleneck while keeping inference efficient. We evaluate AEM with Diffusion Policy and Flow Policy. AEM consistently improves manipulation performance in both simulation and real-world settings, outperforming baselines across clean scenes, cluttered and random scenes, and non-Markovian tasks. Ablation studies further show that history-aware pretraining surpasses single-frame pretraining and direct frame stacking, while reducing inference latency and computational cost.

我们提出了AEM(动作-效果记忆)预训练框架,用于机器人操作,通过视觉-动作历史学习紧凑的时间表示。与以往主要关注单帧视觉编码的机器人表示预训练方法不同,AEM针对操作的时间特性,因为在部分可观测性下,仅凭当前观察往往不足以完成任务。AEM将操作建模为一个以动作驱动的交互过程,通过交错视觉和动作特征,并应用掩蔽建模来恢复不完整历史中的缺失内容,从而学习动作条件下的状态演变。最终视觉标记的Mamba编码输出被用作紧凑的历史表示,作为解码和下游控制的全局上下文。该设计在保持推理高效的同时,保留了单向量时间瓶颈。我们使用扩散策略(Diffusion Policy)和流策略(Flow Policy)对AEM进行了评估。AEM在模拟和现实环境中始终提高了操作性能,在干净场景、杂乱和随机场景以及非马尔可夫任务中均超越了基线。消融研究进一步表明,历史感知的预训练优于单帧预训练和直接帧堆叠,同时降低了推理延迟和计算成本。

Foresight: Iterative Reasoning About Clues that Matter for Navigation

前瞻性:关于导航中重要线索的迭代推理
Zhang, Arthur, Qi, Carl, Su, Donne, Meng, Xiangyun, Zhang, Amy, Biswas, Joydeep
Abstract
Open-world mapless navigation from sparse language instructions requires resolving underspecified goals and inferring which environmental cues are relevant for reaching the goal. For instance, reaching an out-of-view destination may require interpreting ramps, signs, or detours that reveal where to go or which route to take. Prior works are limited by their reliance on known navigation factors and closed-set factor categories, or identify cues before motion planning and miss plan-dependent cues. We argue that pretrained Vision-Language Models (VLMs) can discover novel instruction-relevant cues, but require adaptation to focus on which cues matter and how they should influence motion planning. We realize these ideas in Foresight, a test-time framework in which a finetuned VLM alternates between proposing image-space motion plans and critiquing them using the language goal and visual context. Subsequent plans are conditioned on prior critiques, enabling iterative motion refinement before execution. To align plan critiques and refinements with open-set behavior preferences, we learn a reward model from human feedback and use it to post-train the VLM with reinforcement learning in the plan-critique loop. In offline evaluations and 6 real-world environments, Foresight improves average task success by 37% and reduces interventions per mission by 52% relative to state-of-the-art test-time reasoning and foundation-model baselines, while running in real-time on a Jetson AGX Orin. We will release code, data, and training details to support future work on test-time reasoning for robot motion refinement. Additional videos at: https://amrl.cs.utexas.edu/foresight

从稀疏语言指令进行开放世界无地图导航需要解决不明确的目标,并推断哪些环境线索与实现目标相关。例如,抵达一个视野之外的目的地可能需要解释坡道、标志或绕行,这些都能揭示前往何处或选择哪条路线。先前的研究受限于对已知导航因素和封闭集合因素类别的依赖,或在运动规划之前识别线索而错过依赖于规划的线索。我们认为,预训练的视觉-语言模型(Vision-Language Models, VLMs)能够发现新的与指令相关的线索,但需要适应以关注哪些线索重要以及它们应如何影响运动规划。我们在前瞻性(Foresight)中实现了这些思想,这是一个测试时框架,其中经过微调的VLM在提出图像空间运动计划和使用语言目标及视觉上下文对其进行评估之间交替进行。后续计划基于先前的评估进行条件化,使得在执行之前能够进行迭代的运动优化。为了将计划评估和优化与开放集合行为偏好对齐,我们从人类反馈中学习了一个奖励模型,并利用它在计划-评估循环中使用强化学习对VLM进行后训练。在离线评估和6个真实环境中,前瞻性使平均任务成功率提高了37%,并将每次任务的干预次数减少了52%,相较于最先进的测试时推理和基础模型基线,同时在Jetson AGX Orin上实时运行。我们将发布代码、数据和训练细节,以支持未来在机器人运动优化的测试时推理方面的研究。更多视频请访问:https://amrl.cs.utexas.edu/foresight

G-MAPP: GPU-accelerated Multi-Agent Planning and Perception for Reactive Motion Generation

G-MAPP:基于GPU的多智能体规划与感知加速反应运动生成
Bishnoi, Tanmay, Laha, Riddhiman, Löw, Tobias, Chandy, Jose Alex, Figueredo, Luis F. C., Haddadin, Sami
Abstract
Reactive motion generation in unstructured environments remains an open challenge in robotics. Due to the computational complexity of collision-free motion generation, existing methods either generate global trajectories for static scenarios, or employ models that make conservative assumptions about the environment. This paper identifies the primary bottleneck as the runtime performance demand of planning on high-fidelity environments, and the temporal integration between the perception and planning modules. Therefore, we propose a framework that does not compromise on runtime performance and world representations for perception and planning by accelerating world modeling and vector-field based planning using the GPU. This allows us to achieve faster parallel state exploration for quasi-global trajectory planning, and tighter coupling of the perception-action loop in real-time for dynamic cluttered environments with off-the-shelf depth sensors. We quantitatively evaluate the computation-time and success rate differences for the CPU and GPU versions of our planner, and perform qualitative evaluations of our coupled framework using real-world experiments on a 7-DoF Franka Emika robot. Experimental results demonstrate that our GPU-based framework achieves up to a 5x speedup over the CPU version and successfully avoids collisions across both trivial and challenging physical world scenarios.

在非结构化环境中生成反应性运动仍然是机器人技术中的一个开放挑战。由于无碰撞运动生成的计算复杂性,现有方法要么为静态场景生成全局轨迹,要么采用对环境做出保守假设的模型。本文确定了主要瓶颈为在高保真环境中规划的运行时性能需求,以及感知与规划模块之间的时间集成。因此,我们提出了一种框架,该框架在感知和规划的世界表示上不妥协于运行时性能,通过使用GPU加速世界建模和基于向量场的规划。这使我们能够实现更快的并行状态探索,以进行准全局轨迹规划,并在动态杂乱环境中与现成深度传感器实时紧密耦合感知-动作循环。我们定量评估了规划器的CPU和GPU版本在计算时间和成功率上的差异,并通过在7自由度的Franka Emika机器人上进行真实世界实验,对我们的耦合框架进行了定性评估。实验结果表明,我们基于GPU的框架在速度上比CPU版本快了多达5倍,并成功避免了在简单和具有挑战性的物理世界场景中的碰撞。

From Imitation to Alignment: Human-Preference Flow Policies for Long-Horizon Sidewalk Navigation

从模仿到对齐:用于长距离人行道导航的人类偏好流政策
He, Honglin, Liu, Zhizheng, Ma, Yukai, Zhou, Bolei
Abstract
Autonomous long-horizon sidewalk navigation is essential for micro-mobility applications such as robotic food delivery and assistive electronic wheelchairs. Unlike autonomous driving on the road, long-horizon sidewalk navigation requires precise maneuvering through unpredictable sidewalk terrains and pedestrians, with a lightweight perception stack as minimal as a single monocular RGB camera. While imitation learning (IL) from demonstrations offers a practical solution, the resulting autopilot policy often suffers from compounding errors, a lack of social compliance on sidewalks, and deficiencies in counterfactual reasoning to handle complex situations. To address these challenges, we introduce FlowPilot, a mapless navigation policy that achieves robust and efficient long-horizon navigation performance using only a monocular RGB camera. We first propose to use anchored flow matching as an action representation for policy pre-training on large-scale robot fleet data and to capture the diverse, complex, multimodal distribution of sidewalk navigation behaviors. To bridge the gap between imitation and alignment, we further design a human-in-the-loop preference learning scheme to tune the policy on a small amount of human intervention data. It strengthens the model's counterfactual reasoning and social compliance on sidewalks. We evaluate FlowPilot through extensive simulation and real-world experiments in diverse sidewalk environments. FlowPilot achieves 42% success rate and 66% route completion in simulation, while FlowPilot-HP further improves real-world robustness and social compliance, reducing IR by 40.0% and NIR by 52.1% relative to the base model.

自主的长距离人行道导航对于微型出行应用(如机器人送餐和辅助电子轮椅)至关重要。与道路上的自动驾驶不同,长距离人行道导航需要在不可预测的人行道地形和行人之间进行精确操控,且感知系统的要求最低可仅为单个单目RGB相机。虽然从示范中进行模仿学习(IL)提供了一种实用的解决方案,但所产生的自动驾驶政策往往面临累积误差、缺乏在人行道上的社会合规性以及在处理复杂情况时的反事实推理不足等问题。为了解决这些挑战,我们提出了FlowPilot,这是一种无地图导航政策,仅使用单目RGB相机即可实现稳健和高效的长距离导航性能。我们首先建议使用锚定流匹配作为政策预训练的大规模机器人舰队数据的动作表示,以捕捉人行道导航行为的多样、复杂和多模态分布。为了弥合模仿与对齐之间的差距,我们进一步设计了一种人机协作的偏好学习方案,以在少量人类干预数据上调整政策。这增强了模型在处理人行道上的反事实推理和社会合规性。我们通过在多样的人行道环境中进行广泛的仿真和现实世界实验来评估FlowPilot。FlowPilot在仿真中实现了42%的成功率和66%的路线完成率,而FlowPilot-HP进一步提高了现实世界的稳健性和社会合规性,相较于基础模型,IR降低了40.0%,NIR降低了52.1%。

EgoEngine: From Egocentric Human Videos to High-Fidelity Dexterous Robot Demonstrations

EgoEngine:从自我中心人类视频到高保真灵巧机器人演示
Liu, Yangcen, Cheng, Shuo, Yin, Xinchen, Shin, Woo Chul, Cueva, Alfred, Yang, Yiran, Chen, Zhenyang, Zhang, Chuye, Xu, Danfei
Abstract
Dexterous manipulation is limited by the cost of collecting large-scale robot demonstrations. Egocentric human videos offer a scalable source of diverse manipulation behaviors, but directly using them for robot learning requires bridging two gaps: the visual gap between human and robot observations, and the action gap between human motion and robot-executable action. We propose EgoEngine, a scalable framework for transforming egocentric human manipulation videos into high-fidelity robot data. Given an egocentric RGB video, EgoEngine produces: (i) a high-fidelity robot observation video replacing human with robot while preserving scene context and temporal alignment, and (ii) a task-aligned, executable robot action trajectory under feasibility constraints. Experiments in simulation and on real robots show that EgoEngine enables scalable conversion of human videos into robot data and, to our knowledge, demonstrates the first zero-shot visuomotor dexterous policy learning from egocentric human videos without real-robot demonstrations.

DARRMS -- An Efficient Algorithm for Dynamic Attention Radius in Resource-Constrained Multi-Agent Systems

DARRMS -- 一种用于资源受限多智能体系统的动态注意半径高效算法
Alcorn, Benjamin, Hammad, Eman
Abstract
Multi-agent systems are integral tools for various domains such as robotics, cybersecurity, and autonomous vehicle planning. These types of systems often have constraints on the computational resources, leading to a need for efficient lightweight algorithms. Traditional decision making frameworks often assume ideal conditions, such as full observability and unlimited computational capacity, which do not align with real-world challenges. In this paper, we introduce a new algorithm that allows for reduced demand on computational resources without a large cost of other performance metrics. Agents will limit their observability to some attention radius, which intentionally allows them to ignore parts of the environment that might be unnecessary for action planning. By optimizing both the attention radius and decision-making, our approach enhances coordination and scalability in uncertain environments. Through both theoretical analysis and empirical validation, we demonstrate the effectiveness of adaptive observation in improving system performance and maintaining robust decision-making strategies in resource-constrained systems.

多智能体系统是机器人技术、网络安全和自主车辆规划等多个领域的重要工具。这类系统通常受到计算资源的限制,因此需要高效的轻量级算法。传统的决策框架通常假设理想条件,如完全可观测性和无限计算能力,这与现实世界的挑战并不一致。在本文中,我们提出了一种新算法,允许在不显著增加其他性能指标成本的情况下减少对计算资源的需求。智能体将其可观测性限制在一定的注意半径内,这使得它们可以有意地忽略环境中可能对行动规划不必要的部分。通过优化注意半径和决策过程,我们的方法增强了在不确定环境中的协调性和可扩展性。通过理论分析和实证验证,我们展示了自适应观察在提高系统性能和维持资源受限系统中的稳健决策策略方面的有效性。

EWAM: An Enhanced World Action Model for Closed-Loop Online Adaptation in Embodied Intelligence

EWAM:一种用于具身智能闭环在线适应的增强世界行动模型
Zhou, Xin, Miao, Cong
Abstract
In this paper, we propose the Enhanced World Action Model (EWAM), a closed-loop online adaptation architecture built upon a pretrained and fully frozen Cosmos3 backbone network. Evaluated entirely under a zero-shot task protocol, EWAM is centrally focused on reducing the amount of additional deployment data required to adapt to new task layouts. Notably, no extra task-specific demonstration sets were introduced in any of the evaluations, and no fine-tuning was performed on the backbone network. Its performance gains stem entirely from an inference-time co-reasoning mechanism composed of four inserted lightweight neural layers: the Neural Experience Memory Layer located in the intermediate layers of the Diffusion Transformer (DiT) provides task-relevant execution context; the Neural Anomaly Detection Layer after the state prediction head monitors the divergence between predicted and actual states in real time; the Neural Policy Routing Layer dynamically selects direct execution, conservative replanning, or rollback recovery based on the anomaly severity; and the Neural Action Correction Layer refines the generated action chunks using execution diagnostics. Unlike naive feature fusion, the memory, anomaly detection, and correction modules are deeply integrated into the Cosmos3 forward path in a differentiable manner, with only the final routing decision being a discrete supervised one.

EquiDexFlow: Contact-Grounded SE(3)-Equivariant Dexterous Grasp Generative Flows

EquiDexFlow:基于接触的 SE(3) 等变灵巧抓取生成流
Enwerem, Clinton, Baras, John S., Belta, Calin
Abstract
Most learned dexterous grasp generators relegate contact forces to a downstream verification step, so a kinematically-plausible pose can still violate the conditions for a stable physical grasp. We address this with EquiDexFlow, an SE(3)-equivariant flow-matching model that jointly predicts wrist pose, joint angles, fingertip contacts, surface normals, and contact forces from an object point cloud. Our architecture projects contacts onto the object surface and forces into the Coulomb friction cone by construction, so placement and friction compliance hold without loss penalties. We prove end-to-end SE(3) equivariance and verify it empirically over 200 rotations, with wrist residuals below $0.04^\circ$ and exactly zero joint deviation. Trained on 8,100 force-closure grasps across 81 objects for the 16-DoF Allegro Hand, our model achieves zero friction violations, the best composite score, and the lowest wrench residual among all ablation variants. We retarget decoded fingertip contacts to a 16-DoF LEAP Hand via per-finger inverse kinematics, and our hardware-feasible refinement places every joint at least 5% inside its actuator envelope while preserving wrench balance. On the physical robot, retargeted EquiDexFlow-decoded grasps complete open-loop pick-and-hold trials on all six test objects, with every asymmetric object succeeding at both the canonical pose and a $120^\circ$ co-rotation. Videos, code, and checkpoints are available at https://equidexflow.github.io.

Sparse2Act: Learning Action-Aligned Sparse 3D Representations for Cross-Domain Robot Manipulation

Sparse2Act:学习与动作对齐的稀疏三维表示以实现跨领域机器人操作
Guo, Yu, Yu, Chang, Ma, Siyu, Chen, Yunuo, Yang, Yin, Wu, Ying Nian, Jiang, Chenfanfu
Abstract
Explicit 3D representations are attractive for manipulation because they expose object shape, workspace geometry, and robot-object relations in metric coordinates. However, sparse 3D encoders are often learned through downstream task objectives, tying the representation to a particular data distribution, policy architecture, and action parameterization. We introduce Sparse2Act, an observation-action alignment framework for pretraining sparse point-cloud encoders. The key idea is to use task-space end-effector actions as geometric supervision: masked sparse 3D tokens are trained to organize scene features around the workspace motion paired with the observation. After pretraining, only the encoder initialization is reused by downstream policies, allowing them to retain their own architectures and action spaces, including joint-space commands. On the LIBERO-10 benchmark, our method achieves 86.9% average success after 500 fine-tuning steps. The same pretrained encoder supports LIBERO-to-Meta-World cross-domain transfer, achieving 73.4% average success on the Meta-World-5 benchmark. Ablations on the objective and decoder capacity show that the gains come from the masked action-alignment signal and remain useful across downstream action decoders. In real-world experiments, simulation pretraining followed by limited real-data fine-tuning achieves an average success rate of 72.5% across four tasks, demonstrating effective sim-to-real transfer. These results suggest that robot actions can provide compact geometric supervision for reusable sparse 3D representations.

显式的三维表示在操作中具有吸引力,因为它们以度量坐标展示了物体形状、工作空间几何和机器人与物体之间的关系。然而,稀疏三维编码器通常通过下游任务目标进行学习,这使得表示与特定的数据分布、策略架构和动作参数化相绑定。我们提出了Sparse2Act,一个用于预训练稀疏点云编码器的观察-动作对齐框架。其关键思想是使用任务空间末端执行器动作作为几何监督:被遮蔽的稀疏三维标记被训练以围绕与观察配对的工作空间运动组织场景特征。预训练后,仅重用编码器初始化供下游策略使用,允许它们保留自己的架构和动作空间,包括关节空间命令。在LIBERO-10基准测试中,我们的方法在500次微调步骤后实现了86.9%的平均成功率。相同的预训练编码器支持LIBERO到Meta-World的跨领域迁移,在Meta-World-5基准测试中实现了73.4%的平均成功率。关于目标和解码器容量的消融实验表明,增益来自于被遮蔽的动作对齐信号,并在下游动作解码器中保持有效。在真实世界实验中,模拟预训练后进行有限的真实数据微调,在四个任务中实现了72.5%的平均成功率,展示了有效的模拟到现实迁移。这些结果表明,机器人动作可以为可重用的稀疏三维表示提供紧凑的几何监督。

Stubborn: A Streamlined and Unified Reinforcement Learning Framework for Robust Motion Tracking and Fall Recovery for Humanoids

Stubborn:一个简化且统一的强化学习框架,用于人形机器人稳健的运动跟踪和跌倒恢复
Ren, Xiao, Yang, Yuhui, Weng, Zongbiao, Liu, Zhijie, Kong, He
Abstract
Recent reinforcement learning approaches have shown great promise in improving humanoid motion tracking performance and achieving fall recovery under disturbances. However, most existing works treat motion tracking and fall recovery as different tasks and require multi-stage training with specialized recovery rewards and/or separate recovery policies. Moreover, existing reinforcement learning-based methods often terminate training episodes immediately after severe tracking failures, limiting recovery-oriented exploration in unstable or fallen states. To address the above issues, we propose Stubborn, a streamlined and unified reinforcement learning framework to achieve robust humanoid motion tracking and fall recovery. Specifically, Stubborn uses an asymmetric Actor-Critic architecture and consists of three major components. First, a yaw-aligned tracking representation is adopted to reduce sensitivity to global drift and heading disturbances while preserving gravity-related balance information. Second, we introduce a Bernoulli-based probabilistic termination mechanism that enables the policy to encourage exploration of fall-recovery behaviors under varying failure modes. Third, we propose a probabilistic termination and tracking-error-driven strategy that dynamically reshapes the sampling distribution based on tracking performance, increasing the training efficiency for difficult motion segments and unstable states. Extensive comparisons with SOTA methods and ablation studies show that Stubborn achieved competitive performance, and the proposed probabilistic termination mechanism and adaptive sampling strategy contributed to the performance and robustness gains.

近期的强化学习方法在改善人形机器人运动跟踪性能和在干扰下实现跌倒恢复方面展现出了巨大的潜力。然而,大多数现有研究将运动跟踪和跌倒恢复视为不同的任务,并需要多阶段训练,配合专门的恢复奖励和/或单独的恢复策略。此外,现有的基于强化学习的方法通常在严重的跟踪失败后立即终止训练阶段,限制了在不稳定或跌倒状态下的恢复导向探索。为了解决上述问题,我们提出了Stubborn,一个简化且统一的强化学习框架,以实现稳健的人形机器人运动跟踪和跌倒恢复。具体而言,Stubborn采用了不对称的Actor-Critic架构,并由三个主要组件组成。首先,采用了与偏航对齐的跟踪表示,以减少对全局漂移和航向干扰的敏感性,同时保留与重力相关的平衡信息。其次,我们引入了一种基于伯努利分布的概率终止机制,使得策略能够在不同的失败模式下鼓励探索跌倒恢复行为。第三,我们提出了一种基于概率终止和跟踪误差驱动的策略,动态重塑采样分布,基于跟踪性能提高困难运动段和不稳定状态的训练效率。与最先进的方法进行的广泛比较和消融研究表明,Stubborn实现了具有竞争力的性能,所提出的概率终止机制和自适应采样策略对性能和稳健性提升起到了重要作用。有关实际演示,请参见 https://aislab-sustech.github.io/Stubborn/。

AIR-VLA+: Decoupling Movement and Manipulation via Cascaded Dual-Action Decoders with Asymmetric MoE for Aerial Robots

AIR-VLA+: 通过级联双动作解码器与不对称专家混合模型解耦运动与操作以适应空中机器人
Sun, Jianli, Tian, Bin, Zhang, Qiyao, Liu, Zijian, Wang, Yutong, Cui, Zhiyong, Li, Bai, Lv, Yisheng, Tian, Yonglin
Abstract
Aerial manipulation systems have long suffered from representation coupling in end-to-end control, as platform-level Unmanned Aerial Vehicle (UAV) movement and end-effector-level arm manipulation differ substantially in action scale, dynamics, and control objectives. In this paper, we propose AIR-VLA+, a flow matching action generation architecture specifically designed for aerial manipulation, featuring cascaded dual-action decoders and an asymmetric feature-level Mixture of Experts (MoE). We construct cascaded manipulation and movement decoders, allowing the UAV to unidirectionally observe the manipulator's intent during movement to achieve workflow coordination, while isolating the impact of UAV movement information backpropagation on arm manipulation stability. Addressing the characteristic that UAV movement is highly dependent on high-level semantics and responsible for task state transitions in aerial manipulation, we design an input feature enhancement module for the UAV movement decoder. This module introduces an implicit visual grasp projector to perceive the interaction state between the gripper and the object, and injects compressed global semantic features. Within the UAV movement decoder, we deploy an implicit MoE architecture, enabling different movement experts to spontaneously exhibit capacity inclinations for various task stages during training. Through dense soft blending computation on the feature manifold, the UAV movement is endowed with stronger task-stage adaptability. Experiments on the standardized AIR-VLA benchmark demonstrate that our method comprehensively surpasses all baselines with an overall average score of 48.0. The overall task completion score improves by 80.2\% compared to the single-head $\pi_{0.5}$ policy, effectively mitigating the heterogeneous coordinated control conflicts of composite robots.

Learning to Adapt: Representation-Based Reinforcement Learning for Multi-Task Skill Transfer

学习适应:基于表征的多任务技能迁移强化学习
Naveen, Aryan, Ma, Haitong, Balim, Haldun, Li, Na
Abstract
Reinforcement learning has achieved remarkable success in learning complex control policies, yet its applicability remains limited due to sample inefficiency and poor generalization across tasks. In this work, we propose RepMT-SAC, a framework for multi-task RL that enables efficient knowledge sharing and robust transfer to new tasks. RepMT-SAC uses spectral MDP decomposition to capture transferable dynamics, structuring the value function into a task-agnostic core with a minimal task-specific adjustment. This design allows for strong zero-shot performance on in-distribution tasks and rapid few-shot adaptation to out-of-distribution tasks. We evaluate RepMT-SAC on quadcopter trajectory-following tasks across in-distribution and out-of-distribution contexts, demonstrating that it outperforms baselines by up to 30%.

Bounding Boxes as Goals: Language-Conditioned Grasping via Neuro-Symbolic Planning

将边界框作为目标:通过神经符号规划实现语言条件的抓取
Andreyev, Allison, Eum, Landon, Tiglao, Nestor, Gomez, Romel
Abstract
For robotics to be effectively integrated into household or industrial environments, machines must adapt to natural-language prompts in real time. Although Vision-Language Models (VLMs) have enabled zero-shot generalization in robot task and motion planning (TAMP), current state-of-the-art approaches often remain computationally "heavyweight" or require extensive training on thousands of demonstrations. We present GRASP (Grounded Reasoning and Symbolic Planning), a framework designed as a step toward open-vocabulary tabletop manipulation. Our approach leverages a pretrained VLM to translate natural-language queries into neuro-symbolic goal states, grounded in the physical world via a bounding-box detection pipeline. Unlike methods that rely on fixed color lists or hard-coded coordinates, GRASP enables robots to interpret abstract spatial concepts such as "top shelf" and execute tasks without additional fine-tuning. We achieve 73.3% overall success across 90 real-robot trials at three difficulty levels, requiring no task-specific training.

Liu, Zhe, Jin, Huanbo, Du, Zhaohui, Wang, Zhe, Xu, He, Li, Peijia, Gu, Jiaming, Lu, Quan, Wang, Qi, Ji, Bin, Xiao, Ting
Abstract
Wet-lab robots can improve the reproducibility, throughput, and safety of biomedical experiments, but scaling their learning requires customizable simulators for safe and reproducible task generation, open editable laboratory assets, and efficient pipelines that turn limited demonstrations into usable training data. We present Pipette, an embodied simulation platform, benchmark, and data-efficient augmentation framework for wet-lab robot learning. Pipette releases over 43 open-source and re-editable wet-lab assets, together with an extensible asset-building pipeline. A key component of Pipette is its simulation-based data augmentation pipeline, replaying human demonstrations in simulation, applies lighting, camera, speed, and action perturbations, and filters generated episodes with automatic task success checks, rapidly expanding usable training data from limited manual demonstrations. We further introduce an 11-task wet-lab embodied benchmark covering sample handling, culture-ware manipulation, device operation, and precision placement. With only 30 demonstrations per task, ACT achieves 65.5% average success rate, while simulation augmentation improves SmolVLA from 44.1% to 74.7% and {\pi}0 from 40.4% to 46.5%, validating the effectiveness of Pipette for data-efficient VLA training and evaluation. Pipette also supports natural-language-driven scene construction and task registration, lowering the barrier for non-expert users to define new wet-lab robotic tasks.

Towards Reliable Sequential Object Picking in Clutter: The Runner-up Solution to RGMC 2025

朝着可靠的杂乱环境中顺序物体抓取:RGMC 2025 的亚军解决方案
Yu, Wei, Zhang, Xidan, Zheng, Ziyi, Kong, Weijie, Dong, Huixu
Abstract
As a long-standing challenge in robotic manipulation, stable and efficient grasping in cluttered environments is of great importance in industrial settings. While recent studies have achieved relatively high success rates in grasping from clutter, there remain few mature solutions for more demanding tasks such as sequential object search and sorting. This work addresses sequential object picking in cluttered environments based on the Cluttered Environment Picking Benchmark (CEPB) and presents our solution to the Pick-in-Clutter track of the 10th Robotic Grasping and Manipulation Competition (RGMC) at ICRA 2025. The task poses several key challenges. First, it requires robust and collision-aware grasping with high success rates across a diverse set of objects, including both rigid and deformable ones. Second, it demands efficient search for target objects, which places stringent requirements on the decluttering and searching strategies of the solution. To address the above challenges, we design an integrated hardware-software pipeline that combines object recognition, decluttering, and multi-modal grasping. The main contributions include the hardware design of a multifunctional gripper and novel representations for object distribution and occlusion relationships in cluttered space. This pipeline enables efficient recognition, search, and sequential grasping of objects in clutter, demonstrating strong performance in both laboratory tests and competition scenarios, and ultimately achieving second place in the Pick-in-Clutter track of the RGMC 2025.

SERF: Spatiotemporal Environment and Robot Feature Map for Long-Horizon Mobile Manipulation

SERF:用于长时间移动操控的时空环境与机器人特征图
Kim, Sunghwan, Pak, Byeonghyun, Long, Kehan, Tian, Yulun, Atanasov, Nikolay
Abstract
Long-horizon robot mobile manipulation requires continual reasoning about localization, environment changes, and task progress, all of which are challenging to infer from image observations alone. In this paper, we show that conditioning a mobile manipulation policy on a spatiotemporal feature map improves reasoning over long horizons. The map represents the environment and the articulated robot body as neural points in a shared latent space and is updated online from egocentric observations and proprioceptive state. We update the environment neural points using object-level rigid tracking and the robot neural points using forward kinematics. We use our spatiotemporal environment and robot feature (SERF) map as a state input to a vision-language-action (VLA) model by extracting map tokens from multiple reference frames and spatial scales, providing the policy with both local and global context. We demonstrate SERF on BEHAVIOR-1K, a benchmark for long-horizon mobile manipulation in household environments. Experiments show that the SERF VLA policy outperforms image-only baselines, reaches subgoals faster by following more direct trajectories, improves robustness to scene-configuration shifts, and recovers from object-drop failures.

EmbodiSteer: Steering Embodiment-Agnostic Visuomotor Policies with Joint-Space Guidance for Zero-Shot Cross-Embodiment Deployment

EmbodiSteer:通过关节空间引导实现零-shot跨身体部署的与身体无关的视觉运动策略的引导
Wang, Shihefeng, Lv, Kangchen, Yu, Mingrui, Li, Xiang
Abstract
Scalable robot imitation learning relies on large-scale heterogeneous data from diverse robots or body-free data, making Cartesian end-effector actions a key interface for embodiment-agnostic policy learning. However, end-effector-only abstraction leaves Cartesian policies unaware of the deployed robot body, making them brittle under robot-specific constraints such as whole-body collision avoidance. To overcome this limitation, we present EmbodiSteer, a training-free framework that steers embodiment-agnostic visuomotor policies toward zero-shot, embodiment-aware deployment. EmbodiSteer keeps policy learning in Cartesian space while efficiently lifting inference-time diffusion sampling into the target robot's joint space via forward kinematics and Jacobian-based updates. With whole-body collision-aware guidance over joint trajectories after each denoising step, the arm can be steered away from collisions while preserving learned end-effector behavior. Compared with Cartesian-only execution, EmbodiSteer reduces collision rate by 46.1% and improves task success rate by 28.5% across 9 simulated robots, and further achieves 90.0% collision rate reduction and 36.7% success rate increase on two physical robots in highly constrained scenarios.

可扩展的机器人模仿学习依赖于来自多样化机器人或无身体数据的大规模异构数据,使得笛卡尔末端执行器动作成为与身体无关的策略学习的关键接口。然而,仅依赖末端执行器的抽象使得笛卡尔策略无法感知所部署的机器人身体,从而在特定于机器人的约束条件下变得脆弱,例如全身碰撞避免。为了解决这一限制,我们提出了EmbodiSteer,这是一个无训练的框架,旨在将与身体无关的视觉运动策略引导至零-shot、感知身体的部署。EmbodiSteer在笛卡尔空间中保持策略学习,同时通过正向运动学和基于雅可比的更新有效地将推理时的扩散采样提升到目标机器人的关节空间。在每个去噪步骤后,通过对关节轨迹的全身碰撞感知引导,手臂可以在保持已学习的末端执行器行为的同时,避免碰撞。与仅使用笛卡尔执行相比,EmbodiSteer在9个模拟机器人上将碰撞率降低了46.1%,任务成功率提高了28.5%;在两个高度受限的物理机器人上,进一步实现了90.0%的碰撞率降低和36.7%的成功率提升。我们的项目页面地址为 https://frankwang67.github.io/EmbodiSteer-Page。

Trajectory-Level Redirection Attacks on Vision-Language-Action Models

基于轨迹级的视觉-语言-动作模型重定向攻击
Puthumanaillam, Gokul, Dongre, Vardhan, Thangeda, Pranay, Nayyeri, Hooshang, Hakkani-Tür, Dilek, Ornik, Melkior
Abstract
Vision-language-action (VLA) policies bring natural language into closed-loop robot control, enabling robots to execute manipulation tasks directly from text instructions. The same interface gives text a recurring role in control because the prompt is reused at every replanning step, and each prompt-conditioned action changes the future observations on which the policy acts. Existing VLA attacks study adversarial prompts that elicit targeted low-level actions or make such actions persist across changing images. We identify a stronger trajectory-level failure mode: a prompt that still $\textit{appears}$ to specify the intended task but redirects the final physical outcome. We mathematically formalize this setting as $\textit{command-preserving trajectory redirection}$, a prompt-only threat model in which the attacker chooses one prompt before the episode, all policy and environment components remain fixed, and the prompt must stay close to the benign instruction while omitting target words and correction language. To find such prompts, we introduce an on-policy prompt search method that uses rollouts to discover perturbations whose closed-loop behavior tracks a target task while satisfying the command-preserving constraints. Experiments in simulation and on hardware show that near-benign prompt perturbations can redirect VLA rollouts to attacker-specified targets. These results expose a trajectory-level vulnerability in VLA instruction grounding: text that appears to preserve the intended command can still give an adversary control over the robot's final physical outcome.

GenHOI: Contact-Aware Humanoid-Object Interaction by Imitating Generated Videos without Task-Specific Training

GenHOI:通过模仿生成视频实现接触感知的人形机器人与物体的交互,无需特定任务训练
Bi, Zhihai, Zhang, Qiang, Zhao, Guoyang, Cao, Jiahang, Luo, Xueyin, Zhang, Yushan, Xu, Jinglan, Geng, Ruoyu, Li, Yulin, Luo, Andrew F., Ma, Jun
Abstract
Humanoid-Object Interaction (HOI) is a fundamental capability for humanoid robots, yet it remains challenging due to the tight coupling between dynamic balance and stable interaction with diverse objects. Existing methods often require time-consuming task-specific policy training or rely on rigid trajectory replay, which limits their ability to accommodate novel interaction scenarios. In this work, we present \textit{GenHOI}, a simple yet effective framework that enables humanoid robots to perform diverse object-interaction tasks in a zero-shot manner by directly imitating a single generated video, without task-specific training or physical demonstration data. GenHOI first reconstructs the robot-object scene in simulation and renders a first-frame image, which, together with the language command, conditions the synthesis of a task-oriented interaction video. The generated video is then analyzed to identify interaction-relevant contact events and estimate hand-object contact regions, which are encoded as object-centric geometric constraints that convert visual interaction cues into physically grounded optimization priors. Guided by these priors, the reference motion recovered from the video is refined and smoothed to resolve the scale ambiguity inherent in 2D video generation, while adapting a single reference trajectory to unseen robot-object relative poses. The optimized trajectory is finally executed by a closed-loop tracking controller. We validate the proposed framework in extensive simulation and real-world experiments across diverse object-interaction tasks, including box grasping, asymmetric bimanual chair carrying, table lifting from below, and cylindrical-object enveloping.

RoboProcessBench: Benchmarking Process-Aware Understanding in Vision-Language Robotic Manipulation

RoboProcessBench:视觉语言机器人操作中的过程感知理解基准测试
Xia, Dayu, Shi, Yue, Mu, Yao, Ji, Huiting, Ma, Chaofan, Zhou, Yingjie, Chen, Hua, Liu, Yang, Cao, Jiezhang, Zhai, Guangtao
Abstract
Vision-language models (VLMs) are increasingly explored as visual critics, reward generators, and failure detectors in robotic manipulation. These roles implicitly require models to judge not only final task success, but also how a manipulation execution is physically and temporally progressing. However, existing evaluations fail to test whether VLMs possess fine-grained process understanding. To address this gap, we present RoboProcessBench, a benchmark for process-aware understanding in vision-language robotic manipulation. RoboProcessBench decomposes such capability into two complementary dimensions, \emph{static monitoring} and \emph{dynamic reasoning}, instantiated as 12 diagnostic question families covering phase, contact, motion, coordination, primitive-local progress, temporal order, outcome, and primitive-level transitions. Built from physically grounded execution traces, the curated benchmark corpus ProcessData contains \textasciitilde 58k question-answer pairs across 260 manipulation tasks, which is further split into ProcessData-SFT and ProcessData-Eval for post-training and evaluation purposes. Extensive evaluation of various VLMs on ProcessData-Eval reveals broad limitations across 12 diagnostic task families, suggesting current models still lack robust process-aware understanding of manipulation executions. But with ProcessData-SFT, the post-trained \textit{Qwen2.5-VL-7B} and \textit{InternVL-3-8B} exhibit consistent gains on local state, motion, progress, and primitive-aware cues. These results demonstrate that RoboProcessBench serves as both an evaluation benchmark and a learnable supervision source for developing VLMs capable of monitoring and evaluating robotic manipulation processes.

Abstract
Quadruped robots are capable of traversing a wide range of complex terrains with high flexibility. As highly mobile ground-based intelligent platforms, they can be equipped with modules for navigation control, environmental perception, and intelligent interaction, thereby serving as real-world mobile deployment platforms for various algorithms. In this paper, we introduce Y-BotFrame, an extensible embodied platform that turns a robot into an intelligent ground assistant.

The system maps user natural-language instructions into executable embodied task units that can be carried out by the robot. Y-BotFrame supports natural interaction through voice commands and visual feedback, removing the need for a remote controller and enabling efficient human-robot collaboration. With a highly extensible framework, Y-BotFrame supports plug-and-play integration of new functional modules as well as modular upgrades and iterative development, offering a reference implementation for the real-world deployment of general-purpose, instruction-driven embodied agents.The supplementary video is available at https://xdei-group.github.io/Y-BotFrame/.

EA-WM: Event-Aware World Models with Task-Specification Grounding for Long-Horizon Manipulation

EA-WM:具有任务规范基础的事件感知世界模型用于长时间跨度的操作
Wang, Kailin, Jie, Haoxiang, Yan, Yaoyuan, Zhou, Jiacheng, Heng, Zhiyou
Abstract
Pretrained-feature world models provide a useful substrate for robot imagination, but visual or latent prediction alone does not determine whether an imagined future satisfies task-relevant events. Long-horizon manipulation requires progress signals that are relational, predicate-level, and physically grounded: whether an object has moved, whether a drawer or contact state has changed, whether a placement predicate is satisfied, and whether a candidate future is reliable enough for execution. We introduce EA-WM, an event-aware world-model framework that augments frozen visual-feature dynamics with task-specification-grounded event prediction and verification. EA-WM rolls out candidate futures in pretrained visual-feature space, decodes them into structured event states, and scores them using task-progress, semantic-consistency, physical-feasibility, and uncertainty terms. The verifier guides sampling-based planning, gates candidate actions, and, in the contact-sensitive LIBERO wine-rack setting, selects among PPOgenerated proposals. Across navigation, deformable-object, wall-constrained, and languagedescribed manipulation studies, EA-WM shows that event-aware verification can make featurespace world models more interpretable and better aligned with task progress.

Abstract
Despite the success of vision-based generalist robotic policies, existing tactile-based policies remain tied to fixed embodiments and sensor setups. This is because tactile signals are highly heterogeneous across hardware, making cross-sensor generalization difficult. We present FTP-1,the first generalist foundation tactile policy pretrained to acquire transferable tactile manipulation abilities across diverse sensors and embodiments. FTP-1 supports varied tactile inputs, including image-, array-, and state-based signals, by using heterogeneous encoders to project them into unified morphology-aware latent tokens that are jointly modeled by a shared tactile Transformer expert. Pretrained on around 3,000 hours of tactile manipulation data aggregated from 26 data sources, spanning human and robot demonstrations across 21 sensors, FTP-1 learns tactile skills that transfer beyond the sensors seen during pretraining. Across downstream finetuning experiments spanning 5 hardware configurations, FTP-1 improves contact-rich manipulation on seen sensor setups by +17.2% and, surprisingly, transfers to two previously unseen tactile-sensor setups, achieving a +31% gain in success rate. FTP-1 establishes the first unified foundation baseline for tactile manipulation, providing future tactile policies with a shared model-level starting point.

尽管基于视觉的通用机器人策略取得了成功,现有的基于触觉的策略仍然与固定的实体和传感器配置相关联。这是因为触觉信号在硬件之间高度异质,使得跨传感器的泛化变得困难。我们提出了FTP-1,这是第一个经过预训练的通用基础触觉策略,旨在获取可转移的触觉操控能力,适用于多种传感器和实体。FTP-1支持多种触觉输入,包括基于图像、阵列和状态的信号,通过使用异质编码器将其投影到统一的形态感知潜在标记中,这些标记由共享的触觉Transformer专家共同建模。FTP-1在约3000小时的触觉操控数据上进行了预训练,这些数据来自26个数据源,涵盖了21种传感器的人类和机器人演示。FTP-1学习到的触觉技能能够超越预训练期间所见的传感器。在涵盖5种硬件配置的下游微调实验中,FTP-1在已见传感器配置上的接触丰富操控性能提高了17.2%,并且令人惊讶的是,它能够转移到两个之前未见的触觉传感器配置,实现了31%的成功率提升。FTP-1为触觉操控建立了第一个统一的基础基准,为未来的触觉策略提供了一个共享的模型级起点。预训练模型、数据集、训练代码及更多可视化内容请访问 https://ftp1-policy.github.io。

Redesigning Regularization for Effective Policy Smoothing

重新设计正则化以有效平滑策略
Kobayashi, Taisuke, Yamanaka, Naoto
Abstract
This paper proposes a novel regularization design to effectively smooth policy functions in reinforcement learning. While regularization that enhances ``global'' Lipschitz continuity was initially considered, it has been limited to ``local'' Lipschitz continuity due to a tradeoff between smoothness and expressiveness. However, it has become apparent that the original implementation is cumbersome and does not provide sufficient smoothing, leading to a preference for simpler implementations. This stems from a discrepancy between theory and implementation, and a more appropriate implementation can expect to facilitate smoothing. Therefore, this paper identifies three reasons why the original implementation does not function adequately and provide remedies for them. This modified regularization performs well across multiple tasks and algorithms, successfully achieving smooth motion while improving control performance. Furthermore, by applying it to sim-to-real reinforcement learning for a quadruped robot, it is demonstrated that smooth motion provides robustness against sudden changes in target velocity commands.

本文提出了一种新颖的正则化设计,以有效平滑强化学习中的策略函数。尽管最初考虑了增强“全局”Lipschitz连续性的正则化,但由于平滑性与表达能力之间的权衡,它被限制在了“局部”Lipschitz连续性。然而,显然原始实现繁琐,且未能提供足够的平滑效果,导致对更简单实现的偏好。这源于理论与实现之间的差异,更合适的实现有望促进平滑。因此,本文识别了原始实现未能有效工作的三个原因,并为其提供了补救措施。经过修改的正则化在多个任务和算法中表现良好,成功实现了平滑运动,同时提高了控制性能。此外,通过将其应用于四足机器人在仿真到现实的强化学习中,证明了平滑运动对目标速度指令的突变具有鲁棒性。

Multi-Modal Multi-Agent Robotic Cognitive Alignment enabled by Non-Invasive Consumer Brain Computer Interfaces: A Proof of Concept Exploration

通过非侵入式消费级脑机接口实现的多模态多智能体机器人认知对齐:概念验证探索
Kosmyna, Nataliya, Jenkins, Liz, Sinha, Anoop K.
Abstract
While non-verbal behaviors and expressive movements are essential for natural human-robot interaction, existing methods often overlook a crucial element: the human's internal cognitive state. Frequently, proactive multi-agent systems can interrupt humans at inopportune moments, leading to cognitive overload and decreased task performance. This paper introduces a framework for generating "cognitively aligned" multi-agent interactions, enhancing the ability of robotic systems to contextually defer communications to the user of an agent system during moments of high human mental workload and engagement. We present the design and implementation of a closed-loop architecture that explores the interplay between autonomous task execution and real-time neurophysiological focus. Using a consumer-grade Brain-Computer Interface (BCI), our approach continuously monitors Electroencephalography (EEG) spectral band powers while a human performs an engagement-inducing task. We propose an engagement-driven pipeline where an HTTP-based signaling mechanism places a primary agent's sensory inputs and audio outputs into a holding state upon detecting high engagement. This allows secondary agents to seamlessly process complex, delegated tasks in the background. Once the human's cognitive state returns to a lower cognitive load baseline, the primary agent releases the queued agent message. Our preliminary results demonstrate the feasibility of leveraging real-time signal processing, Large Language Models (LLMs), and physical robotic embodiments to create cognitively-aware, non-intrusive multi-agent systems.

Embedding ISO 10218 Safety Compliance in Robots via Control Barrier Functions for Human-Robot Collaboration

通过控制障碍函数在机器人中嵌入ISO 10218安全合规性以促进人机协作
Parma, Federico, Tonola, Cesare, Pedrocchi, Nicola, Beschi, Manuel
Abstract
Human-Robot Collaboration (HRC) requires strict adherence to safety standards, such as ISO 10218, to prevent harmful interactions. Standard Speed and Separation Monitoring (SSM) filters calculate safe robotic speeds based on conservative assumptions, such as constant human velocity, which prevents accurate predictions of minimum separation distances and causes unnecessary operational halts. This paper proposes a Control Barrier Function (CBF) that explicitly incorporates human acceleration data to analytically forward-predict the minimum human-robot separation distance during a worst-case robotic stopping trajectory. To guarantee safety at the control level, this predictive CBF is integrated as an inequality constraint within a Sequential Quadratic Programming (SQP) framework. Specifically, two methods are proposed: Method I, a CBF-constrained PD safety filter; and Method II, a task-scaling SQP controller that enforces a spatial tube constraint. Simulated and real-world experiments on a UR10e robot evaluate the two proposed methods against a standard industrial SSM module baseline. Results demonstrate that Method II dynamically modulates execution speed and confines spatial deviations. Compared to Method I, Method II achieves a 63\% reduction in mean trajectory error and avoids excessive evasive manoeuvres, ensuring high task throughput while complying with ISO 10218 SSM guidelines.

人机协作(HRC)要求严格遵守安全标准,如ISO 10218,以防止有害的交互。标准速度与间隔监测(SSM)过滤器基于保守假设(如恒定的人类速度)计算安全的机器人速度,这限制了对最小间隔距离的准确预测,并导致不必要的操作暂停。本文提出了一种控制障碍函数(CBF),该函数明确结合了人类加速度数据,以分析性地前向预测在最坏情况下机器人停止轨迹下的人机最小间隔距离。为了在控制层面保证安全,这一预测性CBF被作为不等式约束集成到序列二次规划(SQP)框架中。具体而言,提出了两种方法:方法I,一种CBF约束的PD安全过滤器;方法II,一种任务缩放的SQP控制器,强制执行空间管道约束。在UR10e机器人上进行的模拟和真实世界实验评估了这两种提出的方法与标准工业SSM模块基线的表现。结果表明,方法II动态调节执行速度并限制空间偏差。与方法I相比,方法II在平均轨迹误差上实现了63%的减少,并避免了过度的规避机动,确保了高任务吞吐量,同时遵循ISO 10218 SSM指南。

Proprioceptive-visual correspondence enables self-other distinction in humanoid robots

本体感知-视觉对应促进类人机器人自我与他者的区分
Chen, Yurun, Gao, Tianyuan, Ge, Yizhong, Ban, Shikun, Wang, Yizhou, Xiong, Hongkai, Zeng, Wenjun, Zhu, Wentao
Abstract
Distinguishing self from others is a prerequisite for social intelligence, yet humanoid robots that increasingly share workspaces with humans still lack this ability. Here we show that a humanoid robot can learn self-other distinction from proprioceptive-visual correspondence, without any identity labels or kinematic models. Once established, this distinction bootstraps a predictive self-model that maps joint configurations to three-dimensional body occupancy, capturing how the robot's body changes with action. In multi-agent scenes involving humans or morphologically identical robots, the system reliably identifies itself, learns a 3D self-model, and supports downstream tasks including target reaching, collision-aware motion planning, and human-to-robot motion retargeting. Together, these results outline a route toward bodily self-representation in robots that act and coordinate alongside others in shared physical environments.

WT-UMI: Tactile-based Whole-Body Manipulation via Force-Supervised Contact-Aware Planning

WT-UMI:基于触觉的全身操控通过力监督的接触感知规划

Abstract
Whole-body humanoid manipulation of bulky, deformable, and shared-load objects requires distributed contact sensing and explicit force regulation, yet most imitation policies treat contact force only implicitly. On the other hand, different demonstration sources provide complementary modalities with inherent trade-offs: human demonstrations capture natural contact forces but not robot-executable actions, while teleoperation directly records robot actions but with less natural force regulation. This paper presents \textbf{WT-UMI}, a wearable whole-body tactile interface worn by human operators or mounted on humanoids, providing accurate observations of tactile images, contact forces, and end-effector poses across both human demonstration and humanoid teleoperation modes. We introduce a force-conditioned target-pose correction module that converts measured human poses into contact-aware robot targets by learning corrections from teleoperation data. To leverage the natural force interaction in human data, we propose a force-supervised planner that predicts end-effector pose chunks and contact-force trajectories. The predicted contact force serves as the reference for a tactile-based admittance controller. Across five contact-rich tasks spanning deformable objects, bulky rigid objects, and human--humanoid collaboration, WT-UMI improves success rate and reduces contact-position tracking error over four policy baselines.

Humor Style Drives Laughter, Topic Shapes Acceptability: Evaluating Bilingual Personal and Political Robot-Delivered AI Jokes

幽默风格驱动笑声,话题塑造可接受性:评估双语个人和政治机器人传递的人工智能笑话
Velentza, Anna-Maria, Bosser, Anne-Gwenn
Abstract
Humor plays a central role in human social relationships, and recent advances in computational humor create new opportunities for integrating humor into human-robot interaction (HRI). While large language models (LLMs) can generate diverse forms of humor, it remains unclear how humor style, joke content, and language preference shape perceptions of robot-delivered humor in group settings. In this exploratory study, we employed a mixed factorial design in which participants evaluated AI-generated jokes delivered by a robot in a university classroom. We examined the effects of humor type (Affiliative, Self-Enhancing, Aggressive, Self-Defeating) and joke content (person-related vs. political) on perceived funniness and appropriateness, as well as preferred language. Results show that humor type significantly influences funniness, with Aggressive and Affiliative humor rated higher, while joke content primarily affects appropriateness, with person-related jokes preferred over political ones. Language preference was shaped by both joke content and participants' self-reported fluency and humor practices.

See Selectively, Act Adaptively: Dual-Level Structural Decomposition for Bimanual Robot Manipulation

选择性观察,适应性行动:双层结构分解用于双手机器人操作
Choi, Yoon-Ji, Son, Young-Chae, Lim, Soo-Chul
Abstract
In bimanual robotic manipulation, task-relevant visual information varies with the task stage and context, while the interaction of the two arms shifts between independent and coordinated modes, making policy learning challenging. However, existing monolithic Vision-Language-Action (VLA) policies process diverse visual inputs and interaction patterns through a single shared representation and action generation pathway, often failing to separately account for visual relevance and bimanual interaction structure. To address this issue, we propose a bimanual manipulation VLA framework based on Dual-Level Structural Decomposition. The View-Selective Visual Router dynamically adjusts wrist-view contributions to emphasize relevant visual cues, while the Interaction-Aware Action Mixture-of-Experts (MoE) decomposes action generation into coordinated and arm-wise pathways to adapt to varying bimanual interaction modes. We evaluate the proposed method on six simulated bimanual manipulation tasks in RoboTwin 2.0 and three long-horizon real-world tasks. Our model improves the overall average success rate over a monolithic baseline by 27.7% in simulation and 43.3% in real-world evaluation, while consistently outperforming single-module variants across both settings. These results demonstrate that jointly considering selective visual processing and explicit decomposition of bimanual interaction structures provides an effective inductive bias for robust bimanual manipulation.

EMG-Based Adaptation of Anisotropic Virtual Fixtures for Robot-Assisted Surgical Resection and Dissection

基于肌电信号的各向异性虚拟夹具适应性系统用于机器人辅助外科切除和解剖
Onfiani, Dario, Dyck, Michael, Biagiotti, Luigi, Klodmann, Julian
Abstract
In this paper, we address the development of an adaptive assistance system for robot-assisted laparoscopic surgery, specifically for delicate tasks such as Resection and Dissection. Even if Virtual Fixtures offer significant advantages for guiding a surgeon's movements, conventional Virtual Fixtures are often defined by fixed geometries, lacking the flexibility to adapt to the surgical workflow or the surgeon's immediate intent. To address these limitations, we propose a novel framework for an adaptive and anisotropic virtual fixture. In addition, we introduce an intuitive control interface that modulates the fixture's geometry in real-time based on the surgeon's intent, inferred from EMG signals. This approach allows the surgeon to dynamically expand or disengage the constraint by contracting their forearm muscles, enabling seamless transitions between precise guided motion and free repositioning of the tool. Experimental results from a pilot user study, based on a standardized surgical training task, demonstrate the effectiveness of the proposed method. The system showed significant improvements in task accuracy and movement consistency, alongside a reduction in perceived cognitive load, effort, and frustration.

Abstract
Existing stretch and touch sensors for robots are generally expensive with respect to at least one of material costs, required manufacturing equipment, or manufacturing time. We present and experimentally characterize a conductive fiber made using only inexpensive commercial off-the-shelf parts (conductive thread at $0.07/ft, silicone tubing at $0.94/ft) and tools (loop-style needle threader at $2), which can be manufactured quickly (20 cm length in 2 minutes.) We demonstrate its use as a resistive strain sensor with three applications: Triggering a grasp in a pneumatically actuated assistive finger, sensing the pose of a pneumatically actuated robotic strap, and estimating the pose of a flexible solid. We also demonstrate that it can be used as a capacitive sensor with two applications: First, as a touch sensor which triggers a commercial robot arm to move, and second, as a near-field sensor enabling the robot arm to follow a moving hand. The capacitive sensors are knitted, showcasing the high flexibility of the fiber. We discuss methods for improving manufacturing scalability and their cost trade-offs. Finally, we demonstrate a method for repairing a cut fiber.

Real-Time Execution with Autoregressive Policies

基于自回归策略的实时执行
Lee, Sangkyu, Park, Seohyeon, You, Tackgeun, Caciularu, Avi, Szpektor, Idan, Lim, Hwasup, Yu, Youngjae
Abstract
Real-time execution, enabled by asynchronous inference that ensures both smooth action trajectories and fast reactivity, is critical for realistic deployments of large-scale Vision-Language-Action models. However, recent work on real-time execution primarily focuses on variants of diffusion policies, even though it is more critical for autoregressive policies given their slower rollout speed in synchronous inference. In contrast, we demonstrate that autoregressive policies can achieve real-time execution by adjusting the tokenization horizon and applying constrained decoding, thereby guaranteeing strict latency bounds that enable multi-trajectory decoding to maximize performance. Across simulated and real-world environments, we find that the autoregressive policy consistently outperforms its equivalent-level flow-matching policy counterpart while achieving significantly improved task completion speeds from synchronous inference. Coupled with the inherent advantages of autoregressive policies, such as faster convergence and better generalizability in instruction-following, these results confirm that autoregressive policies can remain a competitive policy type supporting real-time execution.

GeoHAT: Geometry-Adaptive Hybrid Action Transformer for Mobile Manipulation

GeoHAT:用于移动操作的几何自适应混合动作变换器
Zhu, Xiangyu, Wu, Renjun, Ge, Luzhou, Liu, Jinyan, Li, Xuesong
Abstract
Whole-body mobile manipulation requires coordinating mobile base and manipulator under shifting viewpoints, posing challenges in geometric perception and action generation. Current policies either rely on 2D features or sparse 3D representations that lack dense spatial structure, and typically encode arm and base within one action vector that ignores their distinct control demands. Moreover, existing dense fusion strategies risk corrupting pretrained representations under noisy depth while incurring heavy computational overhead. We present GeoHAT, an end-to-end diffusion-based framework built on a simple principle: geometry should be injected only where reliable and attended to only where needed. GeoHAT employs a lightweight Fourier spatial encoder that maps dense per-pixel 3D coordinates into geometric tokens without an additional 3D vision backbone. These tokens are then selectively injected into vision foundation model features through per-token gated fusion modulated by depth validity, preserving the semantic prior while enriching spatial understanding. For action generation, a Hybrid Whole-Body Action Decoder decomposes arm and base into distinct subspaces and lets each action modality attend to its task-relevant visual context through sparse cross-attention, while causal temporal modeling captures intra-timestep coordination and inter-timestep dependencies. Experiments on the ManiSkill-HAB simulation benchmark demonstrate that GeoHAT achieves a 79.3% mean success rate, surpassing the strongest baseline by 23.7%. Furthermore, real-world experiments on diverse tasks also confirm consistent improvements over all baselines.

GIVE: Grounding Human Gestures in Vision-Language-Action Models

GIVE:将人类手势与视觉-语言-动作模型相结合
Liu, Pengfei, Li, Gen, Fan, Junqiao, Ma, Boyu, Jia, Jindou, Xiao, Yang, Yang, Jianfei
Abstract
Human communication is inherently multimodal, where language is often accompanied by non-verbal cues such as gestures to convey intentions. However, current Vision-Language-Action (VLA) models treat robotic manipulation as a pure text-driven task, overlooking the important role of gestures in Human-Robot Interaction (HRI). This often leads to inaccurate intent grounding and unreliable manipulation when language instructions are ambiguous or underspecified. To address this challenge, we propose GIVE (Gesture Intent via Visual-Semantic Enhancement), an effective approach that enhances pre-trained VLA models with human gesture understanding without architectural modifications. Specifically, GIVE incorporates gesture information through two complementary pathways: a visual pathway that overlays hand skeletons and fingertip rays onto robot observations for explicit object grounding, and a semantic pathway that generates high-level descriptions of human gestures and task instructions for robust intent grounding. By jointly leveraging visual and semantic guidance, GIVE enables VLA policies to better associate gestures with manipulation behaviors and adapt to dynamic interaction intents. In real-world HRI experiments, GIVE substantially outperforms the baseline, improving target object recognition accuracy by 40% and overall task success rate by 80%, while demonstrating strong robustness and generalization to unseen spatial layouts and diverse participants.

NavWAM: A Navigation World Action Model for Goal-Conditioned Visual Navigation

NavWAM:一种用于目标条件视觉导航的导航世界动作模型
Azuma, Daichi, Miyanishi, Taiki, Sakamoto, Koya, Kurita, Shuhei, Zhu, Yaonan, Khrapchenkov, Petr, Kawanabe, Motoaki, Iwasawa, Yusuke, Matsuo, Yutaka
Abstract
Goal-conditioned visual navigation requires a robot to act under partial observability by anticipating how its motion will change the future egocentric view and whether that change brings it closer to the goal. Navigation world models provide such visual foresight, but they remain prediction modules that require an external planner to convert predicted futures into closed-loop control. We propose Navigation World Action Model (NavWAM), a diffusion-transformer policy that turns navigation world-model prediction into executable action by representing future observations, goal-progress values, and action chunks in a shared latent sequence. By learning future prediction jointly with the action and value targets that determine closed-loop behavior, NavWAM makes visual foresight directly usable for robot control. We build NavWAM through simulation pretraining and real-robot adaptation, and evaluate it on image-goal navigation against planning-based world models and a representative direct navigation policy. Across offline benchmarks and closed-loop real-robot deployment, NavWAM improves over planning-based world-model baselines in our evaluations while using the default policy mode without CEM-style action search.

SPARC: Reliable Spatial Annotations from Robot Demonstrations at Scale

SPARC:来自机器人演示的可靠空间注释
Blank, Nils, Mattes, Paul, Li, Maximilian Xiling, Suliga, Jakub, Roth, Thomas, Reuss, Moritz, Vanjani, Pankhuri, Lioutikov, Rudolf
Abstract
This work introduces Spatial Annotations from Robot Demonstrations with Reliability Calibration (SPARC), a risk-aware framework that automatically labels robot demonstrations with structured spatial annotations and assigns each annotation a reliability score. Structured spatial annotations, such as bounding boxes, object trajectories, and manipulation phase labels, benefit a broad range of robotics applications from training grounded robot policies and embodied foundation models to motion planning and hierarchical task composition. Existing automated pipelines generate such annotations at scale but provide no reliable quality signal: detector confidence is poorly calibrated for annotation correctness, forcing a choice between accepting noisy labels or discarding useful samples. In contrast to existing automated pipelines, SPARC leverages the spatio-temporal structure inherent to robot tasks to generate a reliability signal, reducing noisy labels and retaining more useful samples. We further introduce Interaction-Aware Bench (IA-Bench), a benchmark that measures model accuracy in grounding the locations of interacted objects in robot demonstrations. On 1.7k human-annotated demonstrations spanning diverse embodiments and scenarios, SPARC significantly outperforms detection-only baselines in localization accuracy while retaining three times more samples at high-precision operating points. Our experiments demonstrate that models finetuned on our annotations achieve state-of-the-art results on object-grounding and pointing benchmarks among similarly sized models, while remaining competitive on broader spatial-reasoning suites without manually verified or annotated training data. Furthermore, policies trained on SPARC-generated annotations outperform baselines in cluttered, visually ambiguous real-world scenes. Code, data, and models are available at intuitive-robots.github.io/sparc-labeling.

本研究介绍了带有可靠性校准的机器人演示空间注释(SPARC),这是一个风险感知框架,能够自动为机器人演示标注结构化空间注释,并为每个注释分配一个可靠性评分。结构化空间注释,如边界框、物体轨迹和操作阶段标签,能够为广泛的机器人应用提供支持,从训练基础机器人策略和具身基础模型到运动规划和分层任务组合。现有的自动化管道能够大规模生成此类注释,但未提供可靠的质量信号:检测器的置信度对于注释的正确性校准较差,迫使用户在接受噪声标签与丢弃有用样本之间做出选择。与现有的自动化管道相比,SPARC利用机器人任务固有的时空结构生成可靠性信号,从而减少噪声标签并保留更多有用样本。我们进一步介绍了交互感知基准(IA-Bench),这是一个评估模型在机器人演示中定位交互对象位置准确性的基准。在1.7k个人工注释的演示中,涵盖了多种体现和场景,SPARC在定位准确性上显著优于仅使用检测的基线,同时在高精度操作点保留了三倍以上的样本。我们的实验表明,基于我们的注释微调的模型在物体定位和指向基准测试中取得了同类模型中的最先进结果,同时在更广泛的空间推理任务中保持竞争力,而无需手动验证或注释的训练数据。此外,基于SPARC生成的注释训练的策略在杂乱且视觉模糊的真实场景中优于基线。代码、数据和模型可在 intuitive-robots.github.io/sparc-labeling 获取。

MCR-Bionic Hand: Anatomical Structural Priors for Dexterous Manipulation

MCR仿生手:灵巧操作的解剖结构先验
Yang, Haosen, Wei, Guowu
Abstract
Dexterous robotic hands are usually formulated as high dimensional active control systems governed by degrees of freedom, actuation, and algorithms. Human hand dexterity, however, is partly encoded in the physical architecture of bones, ligaments, tendons, aponeuroses, and intrinsic muscles. This work describes that contribution as two linked forms of structural intelligence: structural prior generation, in which wrist to finger tenodesis, FDS/FDP routing, and the dorsal extensor hood transform low dimensional posture inputs into default grasp configurations and PIP to DIP coordination; and muscle mediated modulation, in which extrinsic muscles, lumbricals, and interossei regulate MCP posture, distal stability, fingertip force paths, and contact states around that default state. Based on this framework, MCR-Bionic Hand is developed as a 1:1 musculoskeletal biomimetic hand integrating a two row eight bone wrist, cross wrist tendons, anatomical flexor routing, volar plate and collateral ligament constraints, the dorsal extensor hood, and intrinsic muscle pathways within one body. Functional demonstrations and geometric mechanical models show that wrist posture induces multi joint pre shaping, the extensor hood maps PIP posture to a coupled DIP response, and intrinsic plus pathways modulate distal stability and fingertip action direction after grasp formation. Contact rich tasks, including coin rotation, pen transfer, dorsal coin flipping, and cube manipulation, show that MCR-Bionic links low dimensional state generation with fine post contact modulation. These results suggest that anatomical biomimetics is valuable not for visual similarity, but for identifying human hand structures that perform part of control.

灵巧的机器人手通常被视为由自由度、驱动和算法控制的高维主动控制系统。然而,人手的灵巧性部分体现在骨骼、韧带、肌腱、腱膜和内在肌肉的物理结构中。本研究将这种贡献描述为两种相互关联的结构智能形式:结构先验生成,其中腕部到手指的腱连结、深屈肌/浅屈肌的走向以及背侧伸肌罩将低维姿态输入转化为默认抓握配置和PIP到DIP的协调;以及肌肉介导的调节,其中外在肌肉、虫肌和骨间肌调节MCP姿态、远端稳定性、指尖施力路径和围绕该默认状态的接触状态。基于这一框架,MCR仿生手被开发为1:1的肌肉骨骼仿生手,整合了双排八骨腕部、交叉腕腱、解剖屈肌走向、掌板和侧韧带约束、背侧伸肌罩以及内在肌肉通路于一体。功能演示和几何机械模型表明,腕部姿态诱导多关节的预成型,伸肌罩将PIP姿态映射到耦合的DIP响应,而内在加通路在抓握形成后调节远端稳定性和指尖动作方向。包括硬币旋转、笔转移、背侧硬币翻转和立方体操作在内的接触丰富任务表明,MCR仿生手将低维状态生成与细微的接触后调节相结合。这些结果表明,解剖仿生学的价值不在于视觉相似性,而在于识别执行部分控制的人手结构。

$\texttt{WEAVER}$, Better, Faster, Longer: An Effective World Model for Robotic Manipulation

WEAVER:更好、更快、更长的机器人操控有效世界模型
Jain, Arnav Kumar, Wu, Yilin, Farebrother, Jesse, Swamy, Gokul, Bajcsy, Andrea
Abstract
The potential impacts of world models (WMs, i.e., learned simulators) on robotics are far-reaching -- policy evaluation, policy improvement, and test-time planning -- all with limited real-world interaction. To unlock these downstream capabilities, a WM needs to jointly satisfy three desiderata: $\textit{(i)}$ fidelity (i.e., producing simulated trajectories that correlate with reality), $\textit{(ii)}$ consistency (i.e., producing simulated trajectories that are coherent over long horizons), and $\textit{(iii)}$ efficiency (i.e., producing simulated trajectories quickly). We propose $\texttt{WEAVER}$ (World Estimation Across Views for Embodied Reasoning): a WM architecture that simultaneously achieves all three desiderata, providing state-of-the-art results on robotic manipulation tasks. $\texttt{WEAVER}$ is a multi-view WM trained to predict future latents and reward values via a flow-matching loss. We distill the key design decisions across model architecture, memory, and prediction objectives required to unlock the kinds of long-horizon dynamic manipulation tasks that have confounded prior world modeling approaches. We apply $\texttt{WEAVER}$ in robotic hardware, demonstrating its effectiveness at policy evaluation ($\rho$=0.870 correlation with real-world success rate), policy improvement (real-world success rate improvement of $38\%$ on top of the $\pi_{0.5}$ robot foundation model), and test-time planning (real-world success rate improvement of $14\%$ with a $5-10\times$ speedup over prior WMs). $\texttt{WEAVER}$ also demonstrates better performance than prior WMs when evaluated on out-of-distribution scenarios.

世界模型(WMs,即学习的模拟器)对机器人技术的潜在影响深远——政策评估、政策改进和测试时规划——所有这些都需要有限的现实世界交互。为了释放这些下游能力,世界模型需要共同满足三个要求:(i) 保真度(即产生与现实相关的模拟轨迹),(ii) 一致性(即产生在长时间范围内连贯的模拟轨迹),以及(iii) 效率(即快速产生模拟轨迹)。我们提出了WEAVER(跨视角的世界估计用于具身推理):一种同时实现这三项要求的世界模型架构,在机器人操控任务上提供了最先进的结果。WEAVER是一个多视角的世界模型,通过流匹配损失训练以预测未来的潜在状态和奖励值。我们提炼了在模型架构、内存和预测目标方面的关键设计决策,这些决策是解锁以前的世界建模方法所无法解决的长时间动态操控任务所必需的。我们在机器人硬件上应用了WEAVER,展示了其在政策评估(与现实世界成功率的相关性为0.870)、政策改进(在基础模型π_{0.5}上实现38%的现实世界成功率提升)和测试时规划(在现实世界成功率上实现14%的提升,速度比之前的世界模型快5-10倍)方面的有效性。WEAVER在评估分布外场景时也表现出比之前的世界模型更好的性能。代码、模型和视频可在:https://arnavkj1995.github.io/WEAVER/ 获取。

Improving Robotic Generalist Policies via Flow Reversal Steering

通过流反转引导改善机器人通用策略
Tang, Andy, Chen, William, Wagenmaker, Andrew, Finn, Chelsea, Levine, Sergey
Abstract
Generalist policies can learn a wide range of skills from diverse robot datasets. In order to solve or improve on challenging news tasks, we need a way to infer and invoke the appropriate actions from the policy's rich behavioral prior, especially when directly commanding the policy fails. We focus on flow matching generalists and propose Flow Reversal Steering (FRS): a method that takes suboptimal but ``reasonable'' actions, finds their latent noises by passing them through the flow policy in reverse, and maps them to nearby generalist action modes. We evaluate FRS across many simulated and real-world manipulation settings. First, FRS can turn coarse semantic guidance from humans or vision-language models (VLMs) into corresponding good robot actions, improving zero-shot control. These gains can be distilled with behavioral cloning by training an auxiliary policy to output noises that the generalist maps to good actions -- showing up to 95% absolute task success rate boosts in under a minute of training. Finally, FRS enables policy improvement by bootstrapping reinforcement learning with semantic knowledge, improving on several tasks that standard RL fails to improve on.

通用策略能够从多样的机器人数据集中学习广泛的技能。为了应对或改善具有挑战性的任务,我们需要一种方法,从策略丰富的行为先验中推断并调用适当的动作,特别是在直接指令策略失败时。我们专注于流匹配通用策略,并提出了流反转引导(Flow Reversal Steering, FRS):一种采取次优但“合理”动作的方法,通过反向传递流策略找到其潜在噪声,并将其映射到附近的通用动作模式。我们在许多模拟和现实世界的操作环境中评估了FRS。首先,FRS能够将来自人类或视觉-语言模型(Vision-Language Models, VLMs)的粗略语义指导转化为相应的良好机器人动作,从而改善零-shot 控制。这些收益可以通过行为克隆进行提炼,通过训练辅助策略输出通用策略映射到良好动作的噪声——在不到一分钟的训练时间内,任务成功率提升可达95%。最后,FRS通过利用语义知识引导强化学习,从而实现策略改进,改善了标准强化学习未能改善的多个任务。

Mana: Dexterous Manipulation of Articulated Tools

Mana:关节工具的灵巧操控
Yin, Zhao-Heng, Shi, Guanya, Abbeel, Pieter, Liu, C. Karen
Abstract
Articulated tool manipulation remains a major challenge in dexterous robotics due to the need to coordinate internal degrees of freedom and contact-rich interactions. While prior work has largely focused on rigid objects, articulated tool use remains underexplored because of its physical complexity and the difficulty of learning functional grasping and manipulation policies. We present Mana (Manipulation Animator), a general sim-to-real framework that reinterprets dexterous manipulation as an animation problem. Inspired by computer animation, Mana employs a coarse-to-fine pipeline that transforms procedurally-generated grasp keyframes into manipulation trajectories through motion planning and reinforcement learning. The data generation process is largely automatic, requiring only a few mouse clicks to specify functional affordances (<1 minute per tool). Across four articulated tools spanning different scales and joint types, Mana achieves zero-shot sim-to-real transfer for both grasping and in-hand manipulation, demonstrating a scalable approach to dexterous articulated tool use.

Stereo Vision-Based Fall Prediction and Detection using Human Pose Estimation on the AMD Kria K26 SOM

基于立体视觉的人体姿态估计的跌倒预测与检测系统在AMD Kria K26 SOM上的应用
Ramesh, Shreyas Narasimhiah, Rathika, P. D., Sarkar, Mahasweta, Wells, Kristen, Audette, Michel, Paolini, Christopher
Abstract
Background and Objective: Falls among elderly people can cause serious injury and reduce quality of life. Timely prediction and detection are essential to prevent harm and support well-being. We propose a portable, low-power, battery-operated, vision-based fall prediction and detection system using HPE on an AMD Kria K26 System-on-Module (SOM). The objective is a non-intrusive, privacy-preserving system for real-time fall detection. Methods: The system uses an Intel RealSense D455 range-sensing camera connected to the K26 SOM by USB. It captures synchronized RGB and depth frames, 640 x 480 x 3 and 640 x 480 pixels, at 60 FPS. The SOM runs a three-stage pipeline with quantized YOLOX, Anchor-to-Joint (A2J), and fall-detection models. YOLOX identifies human bounding boxes from RGB frames, then discards the RGB frames to preserve privacy. A2J uses depth frames to estimate 15 joint keypoints per person. A CNN uses selected joint coordinates (x, y, z) to classify fall activity. YOLOX was trained on CrowdHuman; A2J on ITOP, MP-3DHP, UR Fall Detection, and a custom SDSU PSG dataset; and the CNN on UR Fall Detection and SDSU PSG. The design used a single-core DPU with a serial pipeline and a dual-core DPU running YOLOX and A2J with multiple threads. Results: Quantized accuracy was evaluated using IoU >= 50% for YOLOX, mAP with a 10-cm rule for A2J, and classification accuracy, (TP + TN)/(TP + TN + FP + FN), for the CNN. Accuracies were 74%, 84.13%, and 75.85%. Throughput improved from 2.5 FPS for the single-threaded pipeline to 4.5 FPS for the multi-threaded version. Conclusion: Results demonstrate the feasibility of privacy-preserving fall detection on an AMD Kria K26 edge device. On-device HPE and fall classification runs without cloud dependency, supporting elderly monitoring and assistive healthcare. Future work will improve model accuracy and speed.

HairPort: In-context 3D-aware Hair Import and Transfer for Images

HairPort:基于上下文的3D感知发型导入与转移
Heidari, Alireza, Alimohammadi, Amirhossein, Lira, Wallace Michel Pinto, Bar-Lev, Adi, Mahdavi-Amiri, Ali
Abstract
Transferring hairstyles between images is an important but challenging task in computer graphics, computer vision, and visual effects. It enables users to explore new looks without physically altering their hair, with applications in virtual try-on systems, augmented reality, and entertainment. Most prior works operate best under small pose gaps, and they fall short under large viewpoint and scale differences, where missing hair content must be synthesized rather than transferred. We propose HairPort, a 3D-aware hairstyle transfer framework that attempts to solve these issues by explicitly separating hair removal from transfer and enforcing geometric consistency before synthesis. We introduce a Bald Converter, which produces realistic bald versions of faces through LoRA-based in-context adaptation of FLUX.1 Kontext. To train our Bald Converter, we introduce a new dataset, Baldy, containing 6,000 paired bald and original images across diverse identities and conditions. We also use a 3D-Aware Transfer Pipeline that reconstructs and re-renders the reference hairstyle from the target viewpoint before compositing it onto the source image. Being 3D aware, our method supports large pose and scale discrepancies between the source and target. Finally, a conditional flow-matching generator synthesizes the transferred result from the bald source and geometry-aligned reference guidance. Together, our method enables accurate, pose-consistent, and identity-preserving hairstyle transfer, outperforming existing methods both qualitatively and quantitatively.

在计算机图形学、计算机视觉和视觉效果领域,发型在图像之间的转移是一项重要但具有挑战性的任务。它使用户能够在不实际改变发型的情况下探索新形象,应用于虚拟试穿系统、增强现实和娱乐等领域。大多数先前的研究在小姿态差异下表现良好,但在大视角和尺度差异下则表现不佳,此时缺失的发型内容必须通过合成而非转移来补充。我们提出了HairPort,一个3D感知的发型转移框架,旨在通过明确将发型去除与转移分开,并在合成之前强制执行几何一致性来解决这些问题。我们引入了一种秃头转换器(Bald Converter),通过基于LoRA的上下文适应FLUX.1 Kontext,生成逼真的秃头面孔版本。为了训练我们的秃头转换器,我们引入了一个新的数据集Baldy,其中包含6000对不同身份和条件下的秃头和原始图像。我们还使用了一个3D感知转移管道,该管道在将参考发型合成到源图像之前,从目标视角重建和重新渲染参考发型。由于具备3D感知能力,我们的方法支持源图像和目标图像之间的大姿态和尺度差异。最后,一个条件流匹配生成器从秃头源图像和几何对齐的参考引导中合成转移结果。综上所述,我们的方法实现了准确、姿态一致且保持身份特征的发型转移,在定性和定量上均优于现有方法。

High-Fidelity Two-Step Image Generation via Teacher-Aligned End-to-End Distillation

通过教师对齐的端到端蒸馏实现高保真度的两步图像生成
Liu, Dongyang, Du, Ruoyi, Liu, David, Jiang, Dengyang, Li, Liangchen, Wu, Qilong, Li, Zhen, Hoi, Steven C. H., Li, Hongsheng, Gao, Peng
Abstract
Few-step diffusion distillation has become increasingly mature for 4-8-step generation, yet pushing further to 2 steps remains challenging. In this work, we introduce Z-Image Turbo++, a high-quality 2-step image generation model distilled from the 8-step Z-Image Turbo teacher. Our method addresses the central bottlenecks of increased task difficulty and limited model capacity in 2-step generation through three simple but effective design choices tailored to this regime. First, we propose Distribution-Aligned Adversarial Learning, which uses teacher-generated images rather than external real images as real samples for GAN training, providing a more attainable and informative adversarial target. Second, we adopt Step-Decoupled Parameterization, assigning independent model parameters to the two denoising steps to better match their distinct capacity demands. Third, we perform End-to-End Training with Iterative Regularization, allowing the first step to receive gradients from final image quality while preserving a meaningful intermediate generation through an explicit step-1 loss. Together, these designs substantially narrow the quality gap between 2-step and 8-step generation in both qualitative and quantitative evaluations, highlighting the potential of carefully tailored distillation strategies for improving the quality-efficiency trade-off in few-step generation.

少步扩散蒸馏在4-8步生成中逐渐成熟,但进一步推进到2步仍然具有挑战性。在本研究中,我们引入了Z-Image Turbo++,这是一个从8步Z-Image Turbo教师模型蒸馏而来的高质量2步图像生成模型。我们的方法通过三种简单但有效的设计选择,针对这一领域的任务难度增加和模型容量有限的核心瓶颈进行了改进。首先,我们提出了分布对齐对抗学习(Distribution-Aligned Adversarial Learning),该方法使用教师生成的图像而非外部真实图像作为GAN训练的真实样本,从而提供了更可达和信息丰富的对抗目标。其次,我们采用了步解耦参数化(Step-Decoupled Parameterization),为两个去噪步骤分配独立的模型参数,以更好地匹配它们各自的容量需求。第三,我们进行端到端训练与迭代正则化(End-to-End Training with Iterative Regularization),使得第一步能够接收来自最终图像质量的梯度,同时通过显式的步骤1损失保持有意义的中间生成。综合来看,这些设计在定性和定量评估中显著缩小了2步生成与8步生成之间的质量差距,突显了精心设计的蒸馏策略在改善少步生成中的质量与效率权衡的潜力。

Analyzing and Improving Fine-grained Preference Optimization in Medical LVLMs

分析与改进医疗领域细粒度偏好优化的视觉语言模型
Mohammadizadehsamakosh, Shayan, Sarkar, Pritam, Sigal, Leonid, Etemad, Ali, Dolatabadi, Elham
Abstract
Large Vision-Language Models (LVLMs) have achieved strong performance across medical imaging tasks, yet they remain prone to factual inconsistencies, poor visual grounding, and misalignment with clinically meaningful feedback. Existing post-training alignment approaches, including Direct Preference Optimization (DPO) and its variants, face three critical limitations in the medical domain: (1) sequence-level reward signals treat clinically critical tokens identically to generic filler text; (2) reliance on static supervised fine-tuning references as preferred responses introduces an off-policy distribution shift, steering optimization toward stylistic artifacts over clinical correctness; and (3) alignment objectives lack explicit visual grounding constraints, leaving models insensitive to subtle yet diagnostically decisive pathological features. Our method leverages a bidirectional token-wise KL regularizer alongside a visual-contrastive grounding objective that pairs clean and lesion-corrupted images to penalize responses generated without adequate visual evidence. Together, these components form a fine-grained, on-policy alignment framework that constructs preference pairs by minimally editing model-generated outputs, correcting only clinically erroneous spans while preserving the original linguistic style. Extensive experiments across medical imaging tasks and clinical text generation benchmarks validate the effectiveness of our approach.

Dual-State Slot Attention: Decoupling Appearance and Identity for Video Object-Centric Learning

双状态插槽注意力:解耦外观与身份以实现视频对象中心学习
Tran, Sieu, Nguyen, Duc, Vo, Hao, Vo, Khoa, Le, Ngan
Abstract
Unsupervised video object-centric learning aims to decompose dynamic scenes into persistent, object-level representations without supervision. However, existing slot-based methods struggle to maintain stable object identity in challenging settings such as rapid motion and partial occlusion. First, they typically encode both the per-frame appearance of an object and its identity across frames in a single slot vector, creating an objective conflict that leads to slot swapping: reconstruction requires sensitivity to transient visual changes, whereas temporal consistency requires invariance to them. Second, the token renormalization used in Slot Attention can amplify weakly attending slots, allowing them to absorb tokens from other objects and destabilize slot-to-object correspondence. We propose Dual-State Slot Attention (DSSA), a fully self-supervised framework that addresses these limitations by separating appearance from identity and by reducing spurious updates from weakly matching slots. DSSA decomposes each slot into a local state for per-frame appearance and an identity state for temporally stable object information, thereby aligning reconstruction and temporal consistency with separate representations. The identity state is updated through a learned recurrent transition that acts as a temporal filter on the local state, while competition-modulated aggregation (CMA) down-weights updates from weakly matching slots and prevents them from absorbing tokens from other objects. Experiments on MOVi-C, MOVi-D, and YouTube-VIS demonstrate that DSSA consistently improves segmentation quality and temporal consistency over prior methods, while also yielding stronger downstream object recognition and video dynamics prediction. Code and models will be made publicly available upon acceptance.

无监督视频对象中心学习旨在将动态场景分解为持久的对象级表示,而无需监督。然而,现有的基于插槽的方法在快速运动和部分遮挡等挑战性环境中难以保持稳定的对象身份。首先,它们通常将对象的每帧外观和跨帧的身份编码到一个单一的插槽向量中,这造成了目标冲突,导致插槽交换:重建要求对瞬时视觉变化敏感,而时间一致性则要求对其不变。其次,插槽注意力中使用的令牌重归一化可能会放大弱关注插槽,使其能够吸收来自其他对象的令牌,从而破坏插槽与对象之间的对应关系。我们提出了双状态插槽注意力(Dual-State Slot Attention, DSSA),这是一个完全自我监督的框架,通过将外观与身份分离并减少来自弱匹配插槽的虚假更新来解决这些限制。DSSA将每个插槽分解为用于每帧外观的局部状态和用于时间稳定对象信息的身份状态,从而使重建和时间一致性与单独的表示对齐。身份状态通过一个学习的递归转移进行更新,该转移作为局部状态的时间滤波器,而竞争调制聚合(Competition-Modulated Aggregation, CMA)则降低来自弱匹配插槽的更新权重,防止其吸收来自其他对象的令牌。在MOVi-C、MOVi-D和YouTube-VIS上的实验表明,DSSA在分割质量和时间一致性方面始终优于先前的方法,同时也带来了更强的下游对象识别和视频动态预测能力。代码和模型将在接受后公开发布。

Context-Aware Feature-Fusion for Co-occurring Object Detection in Autonomous Driving

面向上下文的特征融合用于自动驾驶中的共现物体检测
Singh, Binay Kumar, Lobo, Niels Da Vitoria
Abstract
Object detection in autonomous driving requires precise localization and an inherent understanding of the relational context between co-occurring objects. In extremely complex heterogeneous environments rare classes, small-scale objects, and frequently appearing objects are difficult for standard object detection frameworks to handle. In this paper, we propose a novel framework called Context-Centric Feature Fusion (CCFF), which utilizes two attention-based modules, Local Context Fusion Module (LCFM) uses the RoI-to-RoI self-attention mechanism to resolve spatial interactions, mainly considering small and partially obscured objects, while Global Context Attention Module (GCAM) converts the co-occurrence of objects priors by pooling top-K RoI features into a global context attention token, avoiding the computational overhead of pixel-level global pooling. This fusion of local and object-centric global features yields contextualized embeddings that enhance classification results and co-occurring objects detection. Our method is evaluated on two datasets, Cityscapes and BDD100K which demonstrate significant improvement on relational consistency, achieving a Category-level Consistency Strategy (CCS) of 0.973 and 0.969, respectively. Furthermore, our approach produces substantial gains in small object detection (AP_S: 14.1%) and successfully recovers rare classes such as "Train" that are typically lost in large distributions.

自动驾驶中的物体检测需要精确的定位以及对共现物体之间关系上下文的内在理解。在极其复杂的异质环境中,稀有类别、小规模物体和频繁出现的物体对于标准物体检测框架来说是难以处理的。本文提出了一种新颖的框架,称为以上下文为中心的特征融合(Context-Centric Feature Fusion, CCFF),该框架利用两个基于注意力的模块:局部上下文融合模块(Local Context Fusion Module, LCFM)使用RoI到RoI的自注意力机制来解决空间交互,主要考虑小型和部分被遮挡的物体,而全局上下文注意力模块(Global Context Attention Module, GCAM)通过将前K个RoI特征汇聚成一个全局上下文注意力标记来转换物体的共现先验,避免了像素级全局汇聚的计算开销。这种局部和以物体为中心的全局特征的融合产生了上下文化的嵌入,增强了分类结果和共现物体的检测。我们在两个数据集Cityscapes和BDD100K上评估了我们的方法,结果显示在关系一致性上有显著改善,分别达到了0.973和0.969的类别级一致性策略(Category-level Consistency Strategy, CCS)。此外,我们的方法在小物体检测上也取得了显著提升(AP_S: 14.1%),并成功恢复了通常在大分布中丢失的稀有类别,如“火车”(Train)。我们的效率报告显示,该框架以实时处理图像,额外开销为0.2 FPS。代码可在https://github.com/BinayKSingh/CCFF获取。

ECA: Efficient Continual Alignment for Open-Ended Image-to-Text Generation

ECA:开放式图像到文本生成的高效持续对齐
Kong, Jiangtao, Zhao, Peijun, Chen, Chun-Fu, Do, Youngwook, Hu, Shaohan, Zhou, Tianyi, Shao, Huajie
Abstract
Incremental Learning (IL) for Open-ended Image-to-Text Generation (OpenITG) enables models to continuously generate accurate, contextually relevant text for new images while preserving previously acquired knowledge. Unlike prior studies, this paper addresses a more practical scenario in which the predominant category of visual data shifts over time as environments evolve. In this context, we introduce a new notion of continual alignment, which incrementally adapts the alignment module within pre-trained VLMs to preserve high-quality cross-modal representations. Based on this idea, we propose Efficient Continual Alignment (ECA), a novel exemplar-free IL approach for OpenITG. The key challenge is enabling the model to acquire new, task-specific features while minimizing interference with the established alignment without accessing raw data from previous tasks. To address this, ECA employs three core mechanisms: a Mixture of Query (MoQ) module that adapts task-specific query tokens, a Fisher Dynamic Expansion (FeDEx) that dynamically expands model structure based on a Fisher Information Matrix (FIM)-based metric, and an embedding dictionary with Dictionary Replay (DR) to retain past knowledge. To evaluate ECA's performance, we construct four new IL OpenITG benchmarks that better reflect real-world scenarios. Experimental results demonstrate that ECA significantly mitigates catastrophic forgetting and improves IL performance compared to baseline methods. Code and benchmarks are available at https://github.com/Snowball0823/ECA.

CD-RCM: Generalizable Continuous-Depth Novel View Synthesis for Reflectance Confocal Microscopy

CD-RCM:用于反射共聚焦显微镜的可推广连续深度新视图合成
Imtiaz, Tooba, Rajadhyaksha, Milind, Kose, Kivanc, Dy, Jennifer
Abstract
Reflectance confocal microscopy (RCM) provides noninvasive, cellular-resolution "optical biopsies" of human skin \emph{in vivo} by acquiring en-face images at successive depths, forming a sparse z-stack. Due to optical limitations, these stacks are anisotropic 3D volumes with lateral resolution (0.5 $\mu$m) $\sim$6 times higher compared to axial resolution, which is defined by the optical sectioning (3 $\mu$m), limiting the interpretation of tissue. Our goal is to provide continuous-depth visualization by interpolating intermediate sections and making the 3D volume isotropic. Such a representation permits arbitrary-direction sectioning, including histopathology-like cross-sectional examination, without requiring per-patient optimization. To that end, we introduce the first RCM-specific novel-view synthesis (NVS) approach, CD-RCM, a feedforward model that predicts realistic, unseen depths from sparsely sampled RCM stacks. Classical neural rendering methods focus on reconstruction from surface-level multi-view observations. In contrast to surface-level camera views, RCM can acquire optically sectioned en-face images of tissue beyond the surface up to 200 $\mu$m. However, during visualization of the RCM stacks, observations of the shallower sections (towards the surface) obscure the deeper ones. This unique axial imaging geometry and layer-dependent anatomical organization motivated our development of a tailored architectural and training framework that explicitly accounts for RCM's depth-resolved, occlusive imaging physics. Experiments demonstrate that CD-RCM achieves high-fidelity novel-view synthesis with sub-second inference time.

SalArt-VQA: Diagnosing Whether VLMs Understand Salient Artifacts in Generated Images

SalArt-VQA:诊断视觉语言模型是否理解生成图像中的显著伪影
Sun, Xiaoxiao, Zhang, Ruotian, Huang, Junzhe, Burgess, James, Yeung-Levy, Serena
Abstract
Vision-language models (VLMs) are increasingly used to detect whether AI-generated images contain visible artifacts, yet their ability to analyze such artifacts remains poorly understood. A correct image-level decision can still hide important failures: a model may correctly flag an artifact while relying on the wrong visual cue, selecting the wrong region, or describing a defect that the image does not support. To evaluate these behaviors directly, we introduce SalArt-VQA, a diagnostic benchmark for fine-grained SALient ARTifact understanding in AI-generated images. SalArt-VQA contains 950 images and 3,681 human-authored multiple-choice questions spanning artifact images, matched real reference images, and paired generated reference images. Four aligned question types evaluate presence detection, semantic localization, spatial grounding, and evidence-grounded defect identification, while the reference splits test calibration and abstention when the annotated defect is absent. Across 20 VLMs, SalArt-VQA reveals failures that image-level detection accuracy hides: the strongest model reaches 99.37% detection recall on artifact images but answers all four artifact-side questions correctly on only 53.26% of images. Comparing artifact images with artifact-free references reveals a sensitivity-calibration tradeoff: sensitive models often make unsupported artifact claims, while conservative models avoid false alarms largely by missing real artifacts. These results show that high artifact detection accuracy alone does not imply grounded artifact understanding. SalArt-VQA exposes these hidden failure modes and provides a fine-grained evaluation of whether VLM artifact claims are supported by local visual evidence.

视觉语言模型(VLMs)越来越多地用于检测AI生成的图像中是否存在可见的伪影,但它们分析这些伪影的能力仍然不够清楚。一个正确的图像级决策可能仍然掩盖重要的失败:模型可能正确标记一个伪影,但依赖错误的视觉线索、选择错误的区域,或描述图像不支持的缺陷。为了直接评估这些行为,我们引入了SalArt-VQA,这是一个用于AI生成图像中细粒度显著伪影理解的诊断基准。SalArt-VQA包含950张图像和3,681个由人类撰写的多项选择题,涵盖伪影图像、匹配的真实参考图像和成对的生成参考图像。四种对齐的问题类型评估存在检测、语义定位、空间定位和基于证据的缺陷识别,而参考分割测试在标注缺陷缺失时的校准和放弃。在20个VLMs中,SalArt-VQA揭示了图像级检测准确性所隐藏的失败:最强模型在伪影图像上的检测召回率达到99.37%,但在53.26%的图像上仅正确回答所有四个伪影相关问题。将伪影图像与无伪影参考图像进行比较揭示了敏感性与校准之间的权衡:敏感模型往往会做出不支持的伪影声明,而保守模型则主要通过错过真实伪影来避免误报。这些结果表明,仅仅高的伪影检测准确性并不意味着对伪影的理解是有根据的。SalArt-VQA揭示了这些隐藏的失败模式,并提供了对VLM伪影声明是否得到局部视觉证据支持的细粒度评估。

VLADriveBench: Evaluating CoT-Action Relationship in VLA for Autonomous Driving

VLADriveBench:评估自主驾驶中VLA的CoT-行动关系
Nguyen, Thach, Guo, Danhua, Lampo, Tom, Wu, Fei, Yaman, Burhan
Abstract
Vision-language-action (VLA) models generate chain-of-thought (CoT) reasoning alongside driving trajectories, but existing benchmarks evaluate only trajectory quality and do not assess whether the CoT is relevant, consistent, or causally connected to the driving action. We introduce VLADriveBench, a framework that combines observational metrics (mentioning, hallucination, contradiction, action alignment) with a CoT intervention protocol to provide complementary views of the CoT-action relationship. Applying VLADriveBench to three models across two architectures, we find that the two analyses can diverge sharply: ORION scores highest on observational alignment yet its CoT is epiphenomenal, while Alpamayo v1.5 scores lower yet its CoT is strongly causal, with visual salience gating the extent of CoT influence.

GRIP: Feedback-Guided Prompt Retrieval for Large Multimodal Models

GRIP:用于大型多模态模型的反馈引导提示检索
Allabadi, Garvita, Sodano, Matteo, Estevão, Roberto, Wang, Yuxiong, Adve, Vikram, Kiciman, Emre, Chandra, Ranveer
Abstract
In-Context Learning (ICL) has become a powerful mechanism for adapting Large Language Models (LLMs) to new tasks without fine-tuning. Extending this concept to Large Multimodal Models (LMMs), Multimodal In-Context Learning (M-ICL) relies on retrieving relevant examples, such as images, captions, or question-answer pairs, to guide predictions across tasks like classification, captioning, and visual question answering (VQA). Most existing approaches select in-context examples based on feature-space similarity, assuming that semantically similar samples provide the most useful context. However, our systematic analysis reveals that this assumption does not always hold: visually similar examples are not necessarily those that most effectively enhance in-context learning performance. To address this, we propose the Guided Retrieval of In-context Prompts (GRIP), a learnable vision-only retrieval framework that leverages feedback from LMMs to identify examples that truly improve model predictions. GRIP learns to distinguish beneficial from detrimental in-context examples through contrastive training, refining retrieval beyond pure similarity. Across three multimodal tasks, namely classification, captioning, and VQA, GRIP improves consistently over similarity-based retrieval on Qwen2.5-VL-7B, with its strongest gains in classification on Idefics2-8B. Moreover, we demonstrate that retrievers trained with feedback from one open LMM can be transferred to other models without retraining, including closed-source GPT-4o and Gemini, enabling scalable and cost-efficient deployment of M-ICL. Code will be published upon acceptance.

DIMOS: Disentangling Instance-level Moving Object Segmentation

DIMOS:解耦实例级移动物体分割
Huang, Hongxiang, Ren, Hongwei, Lin, Xiaopeng, Huang, Yulong, Xie, Zeke, Cheng, Bojun
Abstract
Moving instance segmentation (MIS) attracts increasing attention due to its broad applications in traffic surveillance, autonomous driving, and animal tracking. Event cameras record asynchronous brightness changes, providing high temporal resolution and dynamic range, which makes them highly sensitive to motion information. By fusing event and image features, motion cues from events can complement spatial details from images, enhancing the performance of MIS. However, current multimodal MIS methods still struggle to segment small moving instances, as event cameras often yield sparse features under limited resolution. Moreover, event features entangle appearance attributes with motion cues, which further restricts effective cross-modal fusion. To address these challenges, we first propose a dual-disentangling feature extraction framework that separates and extracts appearance and motion information within both image and event modalities, thereby improving feature density. Subsequently, a multi-granularity cross-modal alignment is introduced to align distributionally and semantically consistent features across modalities, enabling more effective fusion with rich spatial and temporal details. The experiment results demonstrate that our method achieves state-of-the-art performance in multimodal MIS, especially for small instances under challenging conditions such as fast motion and low-light settings.

Perceive, Interact, Reason: Building Tool-Augmented Visual Agents for Spatial Reasoning

感知、互动、推理:构建工具增强的视觉智能体以实现空间推理
Li, Changye, Lu, Meng, Wu, Yi, Zhu, Ligeng
Abstract
While recent vision-language models (VLMs) demonstrate strong multimodal understanding, they remain limited in spatial reasoning tasks that require active evidence acquisition and multi-step visual interaction. This limitation suggests that relying solely on implicit visual representations from vision encoders is insufficient for recovering fine-grained spatial evidence. We introduce PERception-Interaction-reason Agent (PERIA), a tool-augmented visual agent for spatial reasoning tasks across map reasoning, visual probing, and vision reconstruction. PERIA uses two lightweight tool families: vision perception tools for exposing textual, symbolic, and spatial evidence, and vision interaction tools for manipulating visual context, tracing paths, and verifying spatial relations. To train PERIA, we develop a unified recipe that combines supervised tool-use trajectory synthesis, composite rewards, and Observation-Relaxed Group-in-Group Policy Optimization (OR-GIGPO) for effective multi-tool behavior. Experiments on 13 benchmarks from 8 datasets show that PERIA-8B improves over the Qwen3-8B backbone by 10.0% on in-distribution benchmarks and 4.4% on out-of-distribution benchmarks, while outperforming previous state-of-the-art baselines of similar size by 7.0%-14.8%. It also achieves performance comparable to much larger models such as Qwen3-VL-235B-A22B-Thinking and GPT-5, demonstrating the effectiveness of PERIA in enhancing spatial reasoning capabilities.

Language-Guided Abstraction for Visual Reasoning

语言引导的视觉推理抽象
Ye, Xu-Jing, Wang, Yuan-Gen, Wang, Ruping
Abstract
The Abstraction and Reasoning Corpus (ARC) is viewed as a critical avenue to Artificial General Intelligence (AGI), as it enables models to learn abstract transformation rules from few-shot examples and then generalize to new tasks. However, prevalent ARC methodology is either pure language or vision-only (i.e., VARC). The former depends heavily on LLMs, consuming billions of parameters. The latter often struggles to capture high-level semantics, leading to overfitting on pixel-level patterns. To bridge this gap, we propose L-VARC, a novel framework that enhances visual reasoning via a language-guided Learning Using Privileged Information (LUPI) branch. Specifically, we design a Semantic Compression Module by feeding a unified, task-agnostic prompt into DeepSeek-V3. In this way, the raw LARC (a crowd-sourced language description dataset) can be substantially refined and structured, fitting with the context length constraint of standard text encoders (e.g., CLIP). Moreover, we design a Cross-Attention Projector to align visual features with semantic embeddings, aiming to guide the training of the ARC model. Notably, the LUPI branch is taken in the training process and will be discarded during inference, thereby yielding a lightweight model with a mere 18 million parameters. Extensive experiments demonstrate that our L-VARC effectively leverages linguistic priors to boost visual reasoning and outperforms state-of-the-art. Ablation studies further confirm the contribution of the two new designs towards the L-VARC framework. The code is available at https://github.com/GZHU-DVL/L-VARC.

抽象与推理语料库(ARC)被视为通向人工通用智能(AGI)的关键途径,因为它使模型能够从少量示例中学习抽象转换规则,并随后推广到新任务。然而,现有的ARC方法要么是纯语言的,要么是仅基于视觉的(即VARC)。前者严重依赖大型语言模型(LLMs),消耗数十亿参数;后者往往难以捕捉高层次的语义,导致在像素级模式上过拟合。为了解决这一问题,我们提出了L-VARC,一个通过语言引导的特权信息学习(LUPI)分支来增强视觉推理的新框架。具体而言,我们通过将统一的、与任务无关的提示输入DeepSeek-V3,设计了一个语义压缩模块。通过这种方式,原始的LARC(一个众包的语言描述数据集)可以被显著精炼和结构化,以适应标准文本编码器(如CLIP)的上下文长度限制。此外,我们设计了一个跨注意力投影器,以将视觉特征与语义嵌入对齐,旨在指导ARC模型的训练。值得注意的是,LUPI分支在训练过程中使用,在推理时将被丢弃,从而产生一个仅有1800万参数的轻量级模型。大量实验表明,我们的L-VARC有效利用语言先验来提升视觉推理,并超越了现有的最先进水平。消融研究进一步确认了这两个新设计对L-VARC框架的贡献。代码可在https://github.com/GZHU-DVL/L-VARC获取。

Learning Task-Aware Sampling with Shared Saliency through Density-Equalizing Mappings

通过密度均衡映射学习任务感知采样与共享显著性
Ip, Tsz Lok, Zhang, Han, Lui, Lok Ming
Abstract
In image and surface-based learning tasks, convolutional features are typically extracted using receptive fields that are sampled uniformly across the entire domain. However, informative structures are rarely distributed uniformly in practice and are often concentrated in localized regions. Such phenomena are particularly common in medical imaging, where pathological changes are spatially confined. Consequently, uniform convolution allocates equal computational effort to both informative and uninformative regions, resulting in inefficient feature extraction and suboptimal utilization of model capacity. To address this issue, we propose a framework for task-adaptive sampling that dynamically redistributes computational attention according to the spatial importance of the data. Specifically, we introduce the Density-Equalizing Convolutional Neural Network (DECNN), which employs density-equalizing mappings to guide convolution through a learned density function. The density function encodes the relative importance of different regions and induces a transformation that enlarges informative areas while compressing less relevant ones. As a result, convolutional receptive fields are redistributed non-uniformly over the domain, enabling denser sampling in task-relevant regions. By coupling this importance-driven transformation with convolution, DECNN performs adaptive feature extraction that focuses computational resources on informative structures. This leads to more efficient use of model capacity, yielding a lightweight yet expressive architecture while simultaneously producing an interpretable saliency map. Experiments on image classification and craniofacial surface analysis demonstrate that DECNN achieves competitive or superior performance with fewer parameters, accurately identifies task-relevant regions, and remains robust under complex geometric variations.

在图像和基于表面的学习任务中,卷积特征通常是通过在整个领域均匀采样的感受野提取的。然而,信息丰富的结构在实际中很少均匀分布,通常集中在局部区域。这种现象在医学成像中尤为常见,其中病理变化在空间上是局限的。因此,均匀卷积对信息丰富和无信息区域分配了相同的计算努力,导致特征提取效率低下和模型能力的次优利用。为了解决这个问题,我们提出了一种任务自适应采样框架,该框架根据数据的空间重要性动态重新分配计算注意力。具体而言,我们引入了密度均衡卷积神经网络(Density-Equalizing Convolutional Neural Network, DECNN),它利用密度均衡映射通过学习的密度函数引导卷积。密度函数编码了不同区域的相对重要性,并诱导出一种变换,扩大信息丰富区域的同时压缩不太相关的区域。因此,卷积感受野在领域上非均匀地重新分配,使得在任务相关区域进行更密集的采样。通过将这种基于重要性的变换与卷积相结合,DECNN实现了自适应特征提取,将计算资源集中在信息结构上。这导致模型能力的更有效利用,产生一种轻量且富有表现力的架构,同时生成可解释的显著性图。在图像分类和颅面表面分析的实验中,DECNN以更少的参数实现了具有竞争力或更优的性能,准确识别任务相关区域,并在复杂几何变化下保持鲁棒性。

Bridging Modal Isolation in Interleaved Thinking: Supervising Modality Transitions via Stepwise Reinforcement

跨越交错思维中的模态隔离:通过逐步强化监督模态转变
Li, Tingyu, Zhou, Le, Li, Siyuan, Wu, Yujun, Xu, Xinglong, Wei, Jingxuan, He, Conghui, Tan, Cheng
Abstract
Interleaved thinking, where a unified multimodal model alternates between textual reasoning and visual generation, has shown promise on spatial and physical tasks. However, in complex long-chain scenarios, we identify a fundamental failure mode: generated images diverge from the textual context while subsequent text ignores the visual evidence, causing the two modalities to alternate without genuinely informing each other. We term this Modal Isolation and attribute it to compounding information loss at modality boundaries. We decompose each reasoning cycle into atomic operations and define modality transition loss, quantifying cross-modal hallucination (text-to-image) and visual utilization deficit (image-to-text) at each boundary. We propose MoTiF (Modality Tiransition Fidelity), a two-stage training framework that directly optimizes these transitions: Reflective SFT trains the model to detect and recover from erroneous visual outputs; Flow-GRPO improves image generation fidelity via reinforcement learning. All training signals in MoTiF derive from transition-level fidelity rather than end-task accuracy. Across four visual puzzle benchmarks, this transition-level supervision substantially improves both cross-modal coherence and final task accuracy. The results demonstrate that effective interleaved reasoning requires explicit structural supervision at modality boundaries, not merely scaling or end-task optimization.

交错思维是一种统一的多模态模型在文本推理和视觉生成之间交替的方式,已在空间和物理任务中展现出潜力。然而,在复杂的长链场景中,我们识别出一种根本性的失败模式:生成的图像与文本上下文偏离,而后续文本忽视视觉证据,导致两种模态交替而没有真正相互启发。我们将此称为模态隔离,并将其归因于模态边界处信息损失的累积。我们将每个推理周期分解为原子操作,并定义模态转变损失,量化每个边界处的跨模态幻觉(文本到图像)和视觉利用缺失(图像到文本)。我们提出了MoTiF(模态转变保真度),一个两阶段的训练框架,直接优化这些转变:反思性SFT训练模型检测并恢复错误的视觉输出;Flow-GRPO通过强化学习提高图像生成的保真度。MoTiF中的所有训练信号均源于转变级别的保真度,而非最终任务的准确性。在四个视觉难题基准测试中,这种转变级别的监督显著提高了跨模态一致性和最终任务的准确性。结果表明,有效的交错推理需要在模态边界处进行明确的结构监督,而不仅仅是规模化或最终任务优化。

Magnifying What Matters: Attention-Guided Adaptive Rendering for Visual Text Comprehension

放大重要内容:基于注意力引导的自适应渲染用于视觉文本理解
Zeng, Shenglai, Wang, Qirui, Guo, Kai, Dai, Xinnan, Long, Xianxuan, Liu, Hui
Abstract
Visual Text Comprehension (VTC) renders text into images for a vision-language model (VLM) to read, sidestepping LLM context-window limits and powering applications from long-page OCR to multi-page memory QA. Yet existing VTC pipelines treat rendering and layout as a fixed, content-agnostic preprocessing step and offer little mechanistic understanding of how VLMs internally process visualized text. Through a focused empirical study on VTC QA tasks, we reveal that VLMs exhibit a localization-without-utilization regime: evidence-localizing attention emerges sharply in the middle-to-late layers and is largely decoupled from answer correctness, yet simply enlarging the localized spans on the rendered page recovers a large fraction of the failures. Building on these observations, we propose AGAR (Attention-Guided Adaptive Rendering), a training-free, model-agnostic method that leverages a VLM's own middle-to-late layer attention to identify the top-K important visual patches, maps them back to word spans, and re-renders the page with those spans enlarged before re-inferring the answer. Extensive experiments across nine VTC benchmarks (short-form, long-context, and multi-page memory QA) and four VLM backbones show that AGAR (i)consistently improves off-the-shelf VLMs as a plug-and-play enhancement, (ii)composes with VLM post-training to yield further gains, and (iii)remains robust under both visual- and text-side input degradation.

Li, Qiru, Zhou, Ao, Jiang, Zhiwei, Cheng, Zifeng, Wang, Cong, Yin, Yafeng, Gu, Qing
Abstract
Multi-label recognition with frozen Vision-Language Models (VLMs) is brittle under distribution shift: standard zero-shot inference scores labels independently, ignoring co-occurrence structure and producing incoherent label sets where dominant concepts suppress weaker but compatible labels. We introduce Bayesian Conditional Priors (BCP) Estimation, a gradient-free test-time adaptation method that injects label dependency without tuning the backbone. BCP views zero-shot logits as a proxy for marginal posteriors under a fixed image-text likelihood and attributes shift-induced errors mainly to a mismatched label prior. For each test image, it selects a high-confidence anchor label and applies an anchor-conditioned Bayesian refinement. This update is closed-form in logit space and admits a pointwise mutual information (PMI) interpretation, explicitly promoting compatible labels and suppressing incompatible ones. BCP operates without target annotations by estimating anchor-conditioned priors online from the unlabeled test stream via lightweight second-order co-occurrence statistics, adding negligible overhead beyond a single forward pass. Across standard multi-label benchmarks and multiple CLIP backbones, BCP consistently outperforms strong TTA baselines, e.g., improving RN50 average mAP from 57.31 to 69.22 and ViT-B/16 from 62.61 to 71.79.

在分布变化下,使用冻结的视觉-语言模型(VLM)进行多标签识别的表现脆弱:标准的零-shot推理独立地评估标签,忽略了共现结构,导致产生不一致的标签集,其中主导概念抑制了较弱但兼容的标签。我们提出了贝叶斯条件先验(BCP)估计,这是一种无梯度的测试时适应方法,通过不调整主干网络来注入标签依赖性。BCP将零-shot logits视为在固定的图像-文本似然下的边际后验的代理,并将因分布变化引起的错误主要归因于标签先验的不匹配。对于每个测试图像,它选择一个高置信度的锚标签,并应用锚条件的贝叶斯细化。此更新在logit空间中为封闭形式,并具有逐点互信息(PMI)解释,明确促进兼容标签并抑制不兼容标签。BCP通过从未标记的测试流中在线估计锚条件先验而无需目标注释,利用轻量级的二阶共现统计,增加的开销可忽略不计,仅需一次前向传播。在标准多标签基准测试和多个CLIP主干网络上,BCP始终优于强大的测试时适应基线,例如,将RN50的平均mAP从57.31提高到69.22,将ViT-B/16从62.61提高到71.79。

MAMVI: 3D Test-Time Adaptation via Masked Multi-View Point Clouds

MAMVI:通过掩蔽多视角点云进行3D测试时适应
Kong, Inseok, Jung, Geunyoung, Jung, Jiyoung
Abstract
3D point cloud models suffer significant performance degradation under distribution shifts caused by sensor noise, occlusions, and environmental changes. Test-time adaptation (TTA) has emerged as a practical paradigm for mitigating this issue during inference. Recently, leveraging multi-view augmentation has shown promise in improving 3D TTA performance. However, existing multi-view approaches are often constrained by sequential optimization that treats each view independently. This sequential optimization leads to substantial inference latency due to repetitive optimization steps, making real-time adaptation impractical. To address this, we propose Masked Multi-View Test-Time Adaptation (MAMVI), which replaces sequential optimization with a unified single-step adaptation. Specifically, MAMVI utilizes a hybrid masking strategy that combines fixed ratios for stability with Beta-distributed sampling for diversity. By aggregating losses across multiple views, MAMVI performs adaptation through a single backward pass based on multi-view consensus. Additionally, a confidence-based adaptive learning rate is used to dynamically adjust the adaptation intensity for each sample. Extensive experiments on ModelNet-40C, ShapeNet-C, and ScanObjectNN-C demonstrate that MAMVI achieves state-of-the-art accuracy on ShapeNet-C and ScanObjectNN-C. Moreover, it remains competitive on ModelNet-40C while delivering 4.9-8.9 times faster inference, making it highly suitable for real-time applications.

3D点云模型在传感器噪声、遮挡和环境变化引起的分布转移下表现出显著的性能下降。测试时适应(TTA)已成为在推理过程中缓解这一问题的实用范式。最近,利用多视角增强在提升3D TTA性能方面显示出良好的前景。然而,现有的多视角方法通常受到顺序优化的限制,这种方法将每个视角视为独立的。这种顺序优化导致由于重复的优化步骤而产生显著的推理延迟,使得实时适应变得不切实际。为了解决这一问题,我们提出了掩蔽多视角测试时适应(MAMVI),它用统一的单步适应替代了顺序优化。具体而言,MAMVI采用了一种混合掩蔽策略,结合了固定比例以确保稳定性和Beta分布采样以增强多样性。通过在多个视角上聚合损失,MAMVI通过基于多视角共识的单次反向传播进行适应。此外,使用基于置信度的自适应学习率动态调整每个样本的适应强度。在ModelNet-40C、ShapeNet-C和ScanObjectNN-C上的大量实验表明,MAMVI在ShapeNet-C和ScanObjectNN-C上达到了最先进的准确率。此外,在ModelNet-40C上也保持了竞争力,同时提供了4.9-8.9倍更快的推理速度,使其非常适合实时应用。我们的代码可在https://github.com/Inseok-kong/MAMVI获取。

YOLO-AMC: An Improved YOLO Architecture with Attention Mechanisms for Building Crack Detection

YOLO-AMC:一种改进的YOLO架构,结合注意力机制用于建筑裂缝检测
Tsai, Ching-Yu, Lin, Chia-Min, Yang, Chih-Hsiang, Wang, Yung-Che, Chiang, Jen-Shiun
Abstract
Crack detection plays an important role in infrastructure inspection and Structural Health Monitoring (SHM). However, cracks typically appear as thin, low-contrast structures and are easily affected by background noise, posing challenges for existing object detection models. This study proposes an improved YOLO-based architecture with integrated attention mechanisms, termed YOLO-AMC (YOLO with Attention Mechanisms for Crack Detection), to enhance automated crack detection performance. Based on YOLOv11, the original C2PSA module is removed, and multiple attention mechanisms, including Global Attention Mechanism (GAM), Residual Convolutional Block Attention Module (Res-CBAM), and Shuffle Attention (SA), are introduced into the multi-scale feature fusion layers of the Neck to strengthen cross-scale feature integration. Experimental results demonstrate that YOLO-AMC consistently outperforms baseline models YOLOv11n and YOLOv8n across multiple evaluation metrics. Among the evaluated attention modules, GAM achieves the best detection performance, obtaining [email protected] = 0.9917 and [email protected]:0.95 = 0.9506 on the test dataset, which are higher than those of YOLOv11 (0.9833 / 0.9112) and YOLOv8 (0.9707 / 0.8921). Furthermore, while maintaining a computational complexity of 7.6 GFLOPs, the proposed model achieves 110.95 FPS on an NVIDIA RTX 4090 platform and approximately 5 FPS on a Raspberry Pi 5 edge device, demonstrating a favorable trade-off between accuracy and deployment efficiency. The implementation code for this study is available on GitHub at https://github.com/CY-Tsai24/YOLO-AMC.

Efficient, Robust, and Anti-Collusion Fingerprinting of Image Diffusion Models

高效、稳健且具反串通能力的图像扩散模型指纹识别
Fei, Jianwei, Dai, Yunshu, Xia, Zhihua, Cao, Xiaochun, Zhou, Jiantao, Piva, Alessandro, Tondi, Benedetta
Abstract
Model fingerprinting, embedding user-specific identifiers (fingerprints) into generated outputs, has recently emerged as a popular solution to protect the intellectual property rights (IPR) of generative text-to-image (T2I) models and prevent unauthorized redistribution. In this work, we reveal a previously unexplored systematic vulnerability in existing generative model fingerprinting methods: they lack robustness against collusion attacks, where multiple attackers combine their models to remove or obscure the fingerprints. To address this issue, we take the first step towards a robust fingerprinting method for T2I models with anti-collusion capabilities. The proposed method encodes strings of bits, namely fingerprints, into the coefficients of a personalized normalization module (PNM) incorporated into T2I models, so that fingerprints can be reliably recovered from any generated image. To defend against collusion attacks and prevent unauthorized model redistribution, we introduce an anti-collusion mechanism based on lossless function-invariant parameter transformations. This mechanism significantly degrades the image generation quality of colluded models, making them effectively unusable. Moreover, our method allows developers to efficiently create multiple copies of fingerprinted T2I models by reparameterizing the PNM without the need for retraining. We also introduce a worst-case optimization strategy to improve robustness against model-level attacks. Our experiments demonstrate that the proposed method achieves high fidelity and robustness across multiple T2I image generation and editing tasks, with fingerprint extraction accuracy exceeding 99.5%. Compared with existing methods, our method demonstrates, for the first time, a notable proactive robustness to collusion attacks by significantly increasing the FID of colluded models.

模型指纹识别是将用户特定标识符(指纹)嵌入生成输出中,近年来已成为保护生成文本到图像(T2I)模型知识产权(IPR)和防止未经授权再分发的热门解决方案。在本研究中,我们揭示了现有生成模型指纹识别方法中一个先前未被探索的系统性脆弱性:它们在面对串通攻击时缺乏稳健性,多个攻击者可以结合他们的模型以去除或模糊指纹。为了解决这一问题,我们迈出了为T2I模型开发具反串通能力的稳健指纹识别方法的第一步。所提出的方法将比特串(即指纹)编码到个性化归一化模块(PNM)的系数中,该模块被纳入T2I模型中,从而可以可靠地从任何生成的图像中恢复指纹。为了防御串通攻击并防止未经授权的模型再分发,我们引入了一种基于无损函数不变参数变换的反串通机制。该机制显著降低了串通模型的图像生成质量,使其有效不可用。此外,我们的方法允许开发者通过重新参数化PNM高效创建多个指纹化的T2I模型,而无需重新训练。我们还引入了一种最坏情况优化策略,以提高对模型级攻击的稳健性。我们的实验表明,所提出的方法在多个T2I图像生成和编辑任务中实现了高保真度和稳健性,指纹提取准确率超过99.5%。与现有方法相比,我们的方法首次展示了对串通攻击的显著主动稳健性,显著提高了串通模型的FID。

Camera and LiDAR BEV Fusion for Cooperative 3D Object Detection on TUMTraf V2X

相机与激光雷达的鸟瞰视图融合用于TUMTraf V2X的协作3D目标检测
Shahbaz, Muhammad, Agarwal, Shaurya
Abstract
We describe a Camera and LiDAR fusion detector developed for the TUMTraf V2X cooperative 3D object detection track of the DriveX 2026 challenge. The detector fuses three roadside cameras with a fused infrastructure-plus-vehicle point cloud in a shared bird's-eye-view space and predicts boxes through a CenterPoint-style head with a generalized IoU regression loss and an IoU quality re-ranking head. Trained on the provided train and validation splits, the model reaches a 3D mAP of 0.85 on the public Codabench test split. While iterating on the system, we observed that 44 of the 50 test frames are also present in the released train (40) and validation (4) splits with their labels. We therefore conducted two additional studies to quantify how this overlap affects the final score: (1) a finetuning run that oversamples the 44 overlapping frames, reaching 0.89 mAP, and (2) a post-processing run that replaces predictions on those frames with the released ground truth, reaching 0.99 mAP (uploaded to our Codabench account for testing but not published on the leaderboard). All three configurations and their per-class results are reported.

Objects Before Words: Object-First Inductive Biases for Grounding Language in Child-View Video

物体优先于词汇:儿童视角视频中语言基础的物体优先归纳偏差
Silva, Sathira, Gebreselasie, Abrham Kahsay, Sheikh, Muhammad Umer, Kuckreja, Kartik, Harari, Daniel, Khan, Muhammad Haris
Abstract
Learning grounded word meaning from natural experience requires resolving two ambiguities in infant-view recordings: when the named referent appears and where it is in a cluttered frame. In SAYCam-style data, caregiver speech is sparse and weakly synchronized with egocentric video, so single-frame contrastive pairing yields noisy positives in which the intended object is absent or entangled with distractors. We propose BabyMind, an object-first bias for child-view contrastive learning under sparse, noisy supervision. BabyMind extracts candidate object embeddings using an offline mask-based region interface, links candidates across a short utterance-centered window into lightweight object files via tracking, and aligns utterances to bags of object files with a prototype-space multiple-instance contrastive objective. Track-coherence and global-object agreement regularizers stabilize learning and transfer object-file structure into the global frame embedding used at evaluation. On SAYCam-S, BabyMind improves Labeled-S 15 forced-choice accuracy by +2.6 points over CVCL and yields consistent gains on in-vocabulary out-of-distribution benchmarks.

Diffusion Transformer World-Action Model for AV Scene Prediction

用于自动驾驶场景预测的扩散变换器世界-动作模型
Sharifullin, Ruslan, Jiang, Benjamin, Chew, Kai Xi
Abstract
Action-conditioned world models let an autonomous vehicle predict future camera scenes from its own planned controls, enabling planning and simulation without real-world rollouts, but at compact, trainable scale the futures are ambiguous and the field's standard distortion metrics actively mislead: they reward a blurry regression mean over a realistic prediction. We confront this with a compact latent world model that, given the present front-camera latent and a sequence of ego-actions, predicts future scene latents a frozen decoder renders to $256 \times 256$ frames up to 8 seconds ahead, evaluated on 150 held-out nuScenes scenes. We first benchmark where to predict: across six frozen encoders spanning four representation families, V-JEPA2 with temporal context reduces steering RMSE by 40% over the best single-frame encoder. We then train a latent Diffusion Transformer (DiT) and, through a controlled diagnosis, identify the four ingredients it needs: spatial tokens, the $x_0$ objective, residual anchoring, and sampling matched to target uncertainty. In a Stable-Diffusion-VAE encode-predict-decode pipeline we expose the central tension: distortion metrics (cosine similarity, SSIM) favor the blurry mean, masking that the diffusion model is far closer to the real frame distribution. Inception-based FID and KID reveal a clean perception-distortion frontier: diffusion attains KID 0.078 versus 0.375 for regression ($4.8\times$ better), and a deployable train-derived calibration makes this practical without test-time ground truth. The model is genuinely action-controllable (steering drives scene displacement, Spearman $\rho = 0.81$, vs $-0.18$ for regression). We trace limited single-pass motion to a shared-present anchor and engineer a compact 1.7M-parameter "jump" model that recovers full ground-truth motion magnitude ($1.02\times$ GT), where single-pass models capture less than half.

A Machine Learning Framework for Real-Time Personalized Ergonomic Pose Analysis

实时个性化人体工学姿势分析的机器学习框架
Atxa, Manex, Simoes, Bruno, Balzategui, Julen
Abstract
This paper introduces a new methodology for real-time prediction of ergonomic and non-ergonomic human poses using volumetric video data in three dimensions. Although the methodology was designed for ergonomic assessments, it can be adapted to other applications requiring real-time analysis of human posture. One aspect that makes this system stand out is its ability to analyze 3D point clouds during the assessment, enabling computation from multiple angles. This overcomes a critical limitation of cameras which provide often a fixed viewpoint, thereby restricting the data available for a thorough postural evaluation, especially when occlusions occur. The system continuously and automatically performs pose inference using the chosen perspective on the real-time streaming data; however, only the poses manually selected and labeled by the user are used to train the personalized deep learning classifier. The methodology has been refined through a case study in which RGB-D cameras captured subjects performing load-lifting tasks, enabling real-time skeletal labeling. The model was trained on this data and, following the training phase, performs inference on new streaming data in real time. This research offers a scalable and pragmatic approach for real-time ergonomic evaluation by combining state-of-the-art 3D data technologies and traditional 2D pose estimation algorithms. It addresses the increasing need for safety and health monitoring in workplace environments, marking a notable contribution to the domain.

Quality-Preserving Imperceptible Adversarial Attack on Skeleton-based Human Action Recognition

基于骨架的人类动作识别的质量保持隐形对抗攻击
Chang, Ziyi, Zhou, Kanglei, Liang, Xiaohui, Shum, Hubert P. H.
Abstract
Adversarial attacks on skeletal human action recognition have received significant attention. However, existing methods typically introduce noise-like perturbations that degrade motion quality post-attack, and thereby are inherently perceptible with recent advancements in S-HAR systems. We discover that this degradation stems from the gap between empirical and true risks during the optimization process of previous adversarial attacks. To address this issue, we propose an attack where adversarial motions are obtained without compromising their motion quality. To minimize the risk gap and preserve motion quality, we propose a distribution-based adversarial attack method without introducing noise-like perturbations. To faithfully evaluate the motion quality, we propose a new metric that aligns with human perception on real-world naturalness. Experiments have been conducted on the state-of-the-art S-HAR methods across two datasets, demonstrating the superiority of our method in both the attack success rate and the post-attack motion quality through qualitative and quantitative analyses. The success of our quality-preserving attack application and distribution-based method raises serious concerns about the robustness of action recognizers, highlighting the need for further enhancements in this domain.

A Multi-Modal Framework with Cross-Subject Pseudo-Labeling and Semantic Alignment for Micro-Gesture Recognition

一种跨主体伪标签和语义对齐的多模态框架用于微手势识别

Abstract
Micro-gestures (MGs) are spontaneous and subtle body movements that frequently convey hidden human emotions. Recognizing MGs in untrimmed videos remains highly challenging due to their extremely low signal-to-noise ratio, severe long-tailed class distribution, and the inherent domain shift encountered in cross-subject evaluation scenarios. In this paper, we propose a comprehensive multi-modal framework for Track 1 of the 4th MiGA-IJCAI Challenge. To capture fine-grained representations, we design a saliency-guided multi-modal extraction pipeline integrating 68-keypoint skeleton joint coordinates, 3D heatmap volumes, and high-resolution RGB visual features. We introduce a gentle square-root smoothed weighting mechanism paired with an Orthogonal Semantic Embedding Loss to protect tail classes without compromising overall recognition capabilities. More importantly, to bridge the cross-subject generalization gap, we propose a Cross-Modal Pseudo-Labeling (CMPL) strategy for unsupervised domain adaptation, which significantly boosts single-modal robustness. A temperature-scaled soft-voting mechanism is finally utilized to alleviate overconfidence during late fusion. Extensive experiments demonstrate that our framework achieves a competitive F1-score of 68.13\%, securing the 4th place.

GeoCFNet: Geometry-Aware Confidence Field Network for Robot-Assisted Endoscopic Submucosal Dissection

GeoCFNet:面向几何的置信场网络用于机器人辅助内镜下黏膜下切除
Tang, Rui, Wang, Guankun, Bai, Long, Yin, Haochen, Gao, Huxin, Lai, Jiewen, Wang, Jiazheng, Ren, Hongliang
Abstract
Advanced surgical robotics has made robot-assisted endoscopic submucosal dissection (ESD) a promising approach for the en-bloc resection of large lesions, with the potential to reduce recurrence and improve long-term outcomes. However, the technical complexity and risk of complications in ESD demand stable and precise visual guidance to maintain an accurate dissection corridor and a safe tissue margin. Dense confidence fields provide an effective representation for this purpose by describing both the preferred dissection region and its spatial transition to surrounding tissue. However, reliable confidence field estimation remains challenging in dynamic endoscopic scenes due to smoke, specular highlights, tissue deformation, weak texture, and the thin geometric structure of the target region. To address these challenges, we formulate dissection guidance as a geometry-aware confidence field estimation problem and propose GeoCFNet, a geometry-aware confidence field network built on a pretrained DINOv3 backbone. GeoCFNet integrates a Token-Differentiated Fusion module to aggregate class-token context with dense patch representations, a SegFormer decoder for confidence regression, and Geometry-Aware Spatial Regularization (GASR) to preserve spatial coherence and local geometric transitions. Experimental results show that GeoCFNet achieves RMSE 0.0480, PSNR 27.1995, SSIM 0.3397, and CC 0.2466, indicating accurate and geometrically stable confidence field estimation for robot-assisted ESD guidance.

SAM-Deep-EIoU: Selective Mask Propagation for Multi-Object Tracking

SAM-Deep-EIoU:用于多目标跟踪的选择性掩码传播
Holmberg, Alexander
Abstract
Multi-object tracking has a heavy-tailed difficulty distribution: most frames are easy for a lightweight base tracker, while a small fraction are intrinsically hard. Video object segmentation (VOS) models can often preserve identity through the hard frames where the base tracker fails, but they are much more expensive in compute and memory. We propose selective mask propagation, a tracking algorithm that dispatches from a base tracker to a VOS model only on windows where an assignment-uncertainty signal fires. The base tracker's output is modified only when the VOS model makes a confident prediction that contradicts the base tracker's identity assignment; weak or inconclusive predictions preserve the base output. The method is training-free, treats both the base tracker and the VOS model as black boxes, and can benefit from replacing the VOS component with a more capable model.

多目标跟踪具有重尾的难度分布:大多数帧对于轻量级基础跟踪器来说是简单的,而只有一小部分帧本质上是困难的。视频目标分割(VOS)模型通常能够在基础跟踪器失败的困难帧中保持身份,但它们在计算和内存方面的开销要大得多。我们提出了选择性掩码传播,这是一种跟踪算法,仅在分配不确定性信号触发的窗口中从基础跟踪器切换到VOS模型。只有当VOS模型做出与基础跟踪器的身份分配相矛盾的自信预测时,基础跟踪器的输出才会被修改;而弱或不确定的预测则保留基础输出。该方法不需要训练,将基础跟踪器和VOS模型视为黑箱,并且可以通过用更强大的模型替换VOS组件来获益。在DanceTrack上,选择性掩码传播改善了三种不同的基础跟踪器。在SportsMOT上,身份保持对于体育分析至关重要,采用全局轨迹关联的SAM3-Deep-EIoU在基准测试中实现了86.8 HOTA的最先进性能。

TetherCache: Stabilizing Autoregressive Long-Form Video Generation with Gated Recall and Trusted Alignment

TetherCache:通过门控回忆和可信对齐稳定自回归长视频生成
Meng, Yu, Luo, Xiangyang, Li, Letian, Jiang, Wenyuan, Gao, Chen, Chen, Xinlei, Li, Yong, Zhang, Xiao-Ping
Abstract
Autoregressive video diffusion models provide a natural formulation for streaming and variable-length video generation by conditioning newly generated frames on previously generated content. However, extending these models to minute-level generation remains challenging: the limited KV-cache budget prevents the model from retaining the full history, while repeatedly conditioning on self-generated frames induces a context distribution shift that accumulates over time, leading to visual artifacts, quality degradation, and temporal drift. In this paper, we propose TetherCache, a training-free and plug-and-play cache management strategy for drift-resistant long video generation. TetherCache organizes the cache into sink, memory, and recent regions, and introduces two complementary mechanisms. First, GRAB (Gated Recall with Attention-Diversity Balancing) selects long-range memory frames using a gated score that combines attention-based relevance with temporal diversity, preserving informative yet diverse historical context under a fixed cache budget. Second, TAME (Trusted Alignment via Memory Editing) lightly edits newly recalled memory tokens by aligning their statistics to a trusted context distribution, reducing the pollution caused by drifted historical features. Built on Self-Forcing, TetherCache consistently improves long-video generation quality on VBench-Long across 30s, 60s, and 240s settings. In particular, for 240s generation, it substantially improves overall and semantic scores while reducing quality drift from 7.84 to 1.33, demonstrating its effectiveness for stable long-horizon autoregressive video diffusion.

自回归视频扩散模型为流式和可变长度视频生成提供了一种自然的表述,通过将新生成的帧与先前生成的内容进行条件化。然而,将这些模型扩展到分钟级生成仍然具有挑战性:有限的KV缓存预算使模型无法保留完整的历史记录,而反复对自生成帧进行条件化会导致上下文分布的偏移,随着时间的推移积累,导致视觉伪影、质量下降和时间漂移。在本文中,我们提出了TetherCache,这是一种无训练且即插即用的缓存管理策略,旨在抵抗漂移的长视频生成。TetherCache将缓存组织为汇聚区、记忆区和最近区,并引入了两种互补机制。首先,GRAB(门控回忆与注意力多样性平衡)使用结合了基于注意力的相关性和时间多样性的门控评分选择长距离记忆帧,在固定的缓存预算下保留信息丰富但多样的历史上下文。其次,TAME(通过记忆编辑实现可信对齐)轻微编辑新回忆的记忆标记,通过将其统计数据对齐到可信的上下文分布,减少了漂移的历史特征造成的污染。在自我强制(Self-Forcing)的基础上,TetherCache在VBench-Long的30秒、60秒和240秒设置中持续提高了长视频生成的质量。特别是对于240秒的生成,它显著提高了整体和语义得分,同时将质量漂移从7.84降低到1.33,证明了其在稳定长时间自回归视频扩散中的有效性。

SeamEdit: A Black-Box VLM-Agnostic Pipeline for Large-Image Semantic Editing

SeamEdit:一种黑箱VLM无关的大图像语义编辑管道
Lyu, Xiangyu, Lei, Dan
Abstract
Semantic region editing for large images must satisfy two requirements at the same time: high generative quality and natural integration with surrounding content. Some related methods rely on white-box models and leave the strong generation capability of closed-source models underexplored. Directly applying closed-source models to tiled editing, however, introduces several failure modes: semantic deformation, canvas-level alignment drift, and visible seam artifacts. This paper presents SeamEdit, a training-free and model-agnostic pipeline that treats any VLM with inpainting capability as a black-box oracle. SeamEdit mitigates these issues through a five-stage post-hoc pipeline: overlay-based tile decomposition, black-box VLM inpainting, geometric and color-consistency correction, seam-risk-based multi-candidate ranking, and dynamic-programming curved seam fusion. The pipeline reduces seam visibility and supports semantic modification of arbitrary tile regions.

大图像的语义区域编辑必须同时满足两个要求:高生成质量和与周围内容的自然融合。一些相关方法依赖于白箱模型,未能充分挖掘闭源模型的强大生成能力。然而,直接将闭源模型应用于平铺编辑会引入几种失败模式:语义变形、画布级对齐漂移和可见接缝伪影。本文提出了SeamEdit,这是一种无训练且无关模型的管道,将任何具有修补能力的VLM视为黑箱神谕。SeamEdit通过五个阶段的后处理管道来缓解这些问题:基于叠加的瓦片分解、黑箱VLM修补、几何和颜色一致性校正、基于接缝风险的多候选排名以及动态规划曲线接缝融合。该管道减少了接缝的可见性,并支持任意瓦片区域的语义修改。

LaME: Learning to Think in Latent Space for Multimodal Embedding via Information Bottleneck

LaME:通过信息瓶颈在潜在空间中学习多模态嵌入的思维方式
Wu, Peixi, Yang, Biao, Ma, Feipeng, Chai, Bosong, Lin, Bo, Yuan, Wei, Yang, Fan, Gao, Tingting, Li, Hebei, Sun, Xiaoyan
Abstract
Reasoning-driven universal multimodal embedding has advanced rapidly by introducing Chain-of-Thought (CoT) reasoning into the embedding pipeline. Despite the strong performance across both general and complex tasks, this paradigm suffers from two core limitations: (i) autoregressive CoT reasoning incurs high computational cost, making it impractical for low-latency retrieval; and (ii) embedding performance is heavily coupled with CoT annotation quality, making large-scale training unreliable. These raise fundamental questions: Is textual CoT the optimal form of reasoning for embedding, and can effective embedding reasoning be accomplished in latent space? To this end, we propose LaME (Latent Reasoning Multimodal Embedding), which formulates embedding-oriented latent reasoning as a weakly supervised information bottleneck. LaME employs K learnable reason tokens as a fixed-capacity bottleneck, completing all reasoning within a single forward pass. The two weak supervision signals structurally decouple contrastive from autoregressive objectives and eliminate dependence on CoT annotations, while a two-stage training pipeline ensures stable convergence. Experiments on MMEB-v2 and MRMR show that LaME achieves competitive performance, surpassing some explicit CoT-based models, while delivering 60x faster inference than explicit CoT methods and 2x faster than latent baselines with throughput comparable to discriminative embedding models. Code will be released.

基于推理的通用多模态嵌入通过将链式思维(Chain-of-Thought, CoT)推理引入嵌入流程而迅速发展。尽管在一般和复杂任务中表现强劲,但这一范式存在两个核心限制:(i)自回归的 CoT 推理带来了高计算成本,使其在低延迟检索中不切实际;(ii)嵌入性能与 CoT 注释质量高度耦合,使大规模训练变得不可靠。这引发了基本问题:文本 CoT 是否是嵌入的最佳推理形式?有效的嵌入推理是否可以在潜在空间中完成?为此,我们提出了 LaME(潜在推理多模态嵌入),将面向嵌入的潜在推理形式化为一种弱监督信息瓶颈。LaME 使用 K 个可学习的推理标记作为固定容量瓶颈,在单次前向传递中完成所有推理。这两个弱监督信号在结构上将对比目标与自回归目标解耦,并消除了对 CoT 注释的依赖,同时双阶段训练流程确保了稳定收敛。在 MMEB-v2 和 MRMR 上的实验表明,LaME 实现了具有竞争力的性能,超越了一些显式 CoT 基础的模型,同时在推理速度上比显式 CoT 方法快 60 倍,比潜在基线快 2 倍,且吞吐量可与判别嵌入模型相媲美。代码将会发布。

Unified MRI Brain Image Translation via Hierarchical Tumor Structure Comparison

通过分层肿瘤结构比较实现统一的MRI脑图像翻译
Cai, Yupeng, Wei, Jia, Zhou, Jianlong
Abstract
Multi-modal MRI brain image translation via available modalities holds significant practical importance in modern medicine, providing robust support for early diagnosis, treatment planning, and outcome assessment of diseases. For this purpose, it is important to ensure the fidelity of the tumor regions after translation. However, existing brain image translation methods ignore the structure information of different tumor regions, which could assist translation models in enhancing the quality and clinical applicability of the translated images. In this work, we propose a novel translation model called HTSCGAN, which is a unified multi-modal brain image translation generative adversarial model integrating the structural information within tumor regions with the aim of improving the quality of brain image translation. Specifically, the generator employs three Patch Contrast Module (PCM) with different patch sizes to capture the hierarchical structural information of the tumor regions. In addition, a pretrained Patch Classifier (PC) and a pretrained Structure-Aware Encoder (SAE) are employed to derive the generated image containing the same tumor region structure as the ground truth image via patch classification loss and tumor perceptual loss, respectively. The experiments on BraTS2020 and BraTS2021 demonstrate strong performance of our model in both translation tasks and down stream segmentation tasks, highlighting its effectiveness in enhancing the quality and clinical relevance of the translated brain images. Our code is available at https://anonymous.4open.science/r/HTSCGAN.

PP-OCRv6: From 1.5M to 34.5M Parameters, Surpassing Billion-Scale VLMs on OCR Tasks

PP-OCRv6:从150万到3450万参数,在OCR任务中超越十亿规模的视觉语言模型

Abstract
Vision-Language Models (VLMs) have achieved impressive results on general vision-language tasks, yet they suffer from hallucination, imprecise localization, and prohibitive computational cost when applied to dedicated OCR scenarios. This paper presents PP-OCRv6, a lightweight OCR system that combines architectural innovation with data-centric optimization. PP-OCRv6 redesigns the backbone, detection neck, and recognition neck around a unified MetaFormer-style building block with structural reparameterization, decoupling spatial token mixing from channel mixing and supporting both tasks through task-specific stride configurations. Three model tiers (medium, small, tiny) share the same block primitives, covering deployment scenarios from server to edge. On our in-house benchmarks, PP-OCRv6_medium achieves 83.2% recognition accuracy and 86.2% detection Hmean, outperforming PP-OCRv5_server by +5.1% and +4.6% respectively while surpassing Qwen3-VL-235B, GPT-5.5, and Gemini-3.1-Pro with orders of magnitude fewer parameters. The tiny tier achieves 3.9$\times$ faster inference than PP-OCRv5_mobile on Intel Xeon CPU while maintaining comparable accuracy.

Fully Distributed Multi-View 3D Tracking in Real-Time

实时全分布式多视角三维跟踪
Hernandez, Byron, Li, Fangyu, Wu, Aotian, Shin, Paul J., Purandare, Kaustubh, Medeiros, Henry
Abstract
Multi-camera tracking with overlapping fields of view typically relies on centralized fusion, which creates computational bottlenecks that prevent deployment at scale. We present MV3DT, a fully distributed framework for real-time multi-view 3D tracking that achieves accurate identity propagation and occlusion recovery through peer-to-peer coordination, eliminating the need for central aggregation. Each camera node executes a lightweight modular pipeline comprising monocular 3D perception, distributed multi-view association, and collaborative fusion via lightweight messaging. MV3DT achieves 94.3% IDF1 and 93.3% MOTA on WILDTRACK, competitive with state-of-the-art centralized methods, while demonstrating superior scalability by sustaining 30 FPS on 100 cameras with less than 10 ms inter-camera latency and only 2.2% communication overhead. MV3DT operates in a zero-shot regime given camera calibrations, requiring no scene-specific learning and making it directly deployable in new environments. These results establish MV3DT as a practical solution for real-time multi-view tracking in large-scale overlapping camera networks.

Cascade Classification of Dermoscopic Images of Skin Neoplasms with Controllable Sensitivity and External Clinical Validation

具有可控灵敏度的皮肤肿瘤皮肤镜图像级联分类及外部临床验证
Kozachok, Elena S., Seregin, Sergey S., Kozachok, Aleksandr V., Latyshev, Ilya P., Samovarov, Oleg I.
Abstract
Purpose. To compare deep learning architectures and classification schemes for dermoscopic images of skin neoplasms and assess their generalization on transfer from open international datasets to independent clinical datasets of Russian practice. Methods. Four architectures (ViT-B/16, Swin-S, ConvNeXt-S, EfficientNetV2-S) were compared in three schemes: binary (malignant/benign), single-stage four-class (benign, MEL, SCC, BCC), and a two-stage cascade (binary triage, then three-class differentiation MEL/SCC/BCC). All models used ImageNet-pretrained weights and a single augmentation protocol on aggregated open ISIC Archive data, and were evaluated on an internal held-out sample and two clinical datasets (Melanoscope AI mobile system; Sechenov University). Results. Internally the binary stage attains ROC-AUC 0.952-0.966; on Sechenov University it drops to 0.797-0.893, sensitivity to 0.53-0.67, and ECE rises from 0.02 to 0.27-0.39 with underestimation of malignancy, quantifying a generalization gap in ranking and calibration. Paired tests confirm one inter-architecture result on clinical data: the deficit of ViT-B/16 at the binary stage (p<0.05); at the differentiation stage no architecture has a proven advantage. The cascade raises macro F1 over single-stage four-class classification for most architectures, but significantly only for ViT-B/16, by recovering malignant lesions assigned to the dominant benign class. On ISIC MILK10k, direct 11-class classification yields mean-class sensitivity 0.525. Conclusion. A tunable triage threshold gives sensitivity control not attainable in standard single-stage (argmax) classification and better reproduces clinical differential-diagnosis logic. The persistent generalization gap mandates external clinical validation and recalibration before deployment.

An Extensible and Lightweight Unified Architecture for Demosaicing Pixel-bin Image Sensors

一种可扩展且轻量化的统一架构用于去马赛克像素分箱图像传感器
Kumar, Saurabh, Yenneti, Nutan Sairam
Abstract
Pixel-bin image sensors are becoming the default choice for smartphone cameras due to their resolution vs light-gathering trade-off. However, their larger inter-color separation compared to the Bayer color filter array (CFA) makes them challenging to demosaic. Furthermore, existing deep learning-based demosaicing methods are CFA-specific, requiring multiple individual models that take up precious onboard resources and demand larger development and maintenance efforts. In this work, we propose a modular unified architecture for demosaicing various pixel-bin sensors that provides higher image quality while being extensible and lightweight. Additionally, to enable plug-and-play operation, we introduce a learning-free CFA-identification module to detect the CFA type of raw data accurately.

Iterative Visual Thinking: Teaching Vision-Language Models Spatial Self-Correction through Visual Feedback

迭代视觉思维:通过视觉反馈教导视觉-语言模型进行空间自我修正
Tripathy, Animesh, Krishnan, Aswanth
Abstract
Vision-language models (VLMs) achieve strong singleshot spatial grounding, yet lack any mechanism to observe and correct their own predictions. We find that naively prompting a VLM to iterate over rendered visualizations of its predictions causes catastrophic failure: [email protected] on referring expression comprehension collapses from 79.6% to 48.7% (a 31 percentage point drop), revealing a fundamental gap between grounding capability and self-correction ability. We propose Iterative Visual Thinking (IVT), a closed-loop framework in which the model predicts a bounding box, observes the prediction rendered on the image, and iteratively refines through visual feedback. A two-phase training recipe closes the self-correction gap: first, we exploit the base model's own predictions as realistic errors and prompt a teacher VLM to generate corrective reasoning traces, yielding supervised data without human annotation; second, we apply Group Relative Policy Optimization (GRPO) with a simple IoU reward to stabilize multi-step refinement. On a mixed benchmark spanning RefCOCOg, Ref-Adv, and Ref-L4 (505 test samples), SFT warm-up with IVT surpasses the single-shot base model on every metric: [email protected] rises to 82.0% (+2.4pp), [email protected] to 74.1% (+3.2pp), and [email protected] to 48.3% (+2.8pp). GRPO further reduces per-step IoU degradation by 5x, stabilizing the refinement trajectory. All training uses only 2,400 samples on a single GPU, demonstrating that spatial self-correction is a learnable capability that can be instilled at modest scale.

Transformer-Guided Graph Attention for Direct Cardiac Mesh Reconstruction: A Structural Digital Twin Framework

基于变换器引导的图注意力用于直接心脏网格重建:结构数字双胞胎框架
S, Abhishek H, Ganamukhi, Akash, Suresh, Abhimanyu, Hiremath, Aditya G, Honnavalli, Prasad B, Balasubramanyam, Adithya
Abstract
Building patient-specific cardiac models sits at the heart of precision cardiology, yet getting those models into clinical use keeps running into the same wall: mesh generation is slow, messy, and frustrating. The standard workflow -- segmenting the image, running Marching Cubes, and then manually cleaning up the result -- is time-consuming, inconsistent across operators, and demands specialist knowledge most clinical teams do not have. We take a fundamentally different approach. Instead of treating segmentation and mesh generation as two separate problems, we train a single end-to-end network that goes directly from a raw 3D medical image to a smooth, simulation-ready cardiac surface mesh. The core is a 3D Swin Transformer encoder-decoder that extracts volumetric features from CT or MRI volumes, paired with a Graph Attention Network (GAT) head that iteratively deforms a template mesh to fit the patient's cardiac boundary. We tested on the MM-WHS 2017 benchmark using both CT and MRI. Segmentation scores were competitive (Dice of 0.84 on CT, 0.83 on MRI), but the primary focus is mesh quality: mean Chamfer distance of 1.8 mm, with 95th-percentile surface distance below 5 mm. Every mesh is produced in a single forward pass -- no Marching Cubes, no smoothing filters, no manual cleanup. We argue that for cardiac digital twin pipelines, geometric fidelity and topological correctness matter more than pixel-level Dice scores. By removing the post-processing bottleneck, this approach makes patient-specific cardiac simulation substantially more accessible for clinical use.

Visual Place Recognition in Forests with Depth-Aware Distillation

基于深度感知蒸馏的森林视觉位置识别
Nedov, Walter, Rahman, Saimunur, Katuwandeniya, Kavindie, Hall, David, Roy, Kaushik, Moghadam, Peyman
Abstract
Visual place recognition in natural forest environments remains challenging due to repetitive vegetation, weak structural cues, and significant appearance variation across traversals. To address this limitation, this paper proposes a lightweight depth-aware distillation framework that injects geometric cues into a DINOv2-based place recognition model, while maintaining its pre-trained descriptor space. Evaluated on the recent WildCross benchmark, the proposed approach yields gains over an appearance-only counterpart, providing robustness to appearance variations. These results demonstrate the importance of depth as a strong complementary modality for place recognition in natural environments and identify depth-aware distillation as a promising direction for more robust forest perception.

TimeLens: On-Device Artifact Recognition with Retrieval-Augmented Question Answering for the Grand Egyptian Museum

TimeLens:针对大埃及博物馆的设备内文物识别与检索增强问答
Hesham, Rawan, Ashraf, Ali, Ahmed, Amr, Alaa, Malak, Ahmed, Omar, Wagih, Omar
Abstract
TimeLens is an AI-powered bilingual mobile guide for the Grand Egyptian Museum (GEM). Pointing a phone at an exhibit, a visitor sees the artifact recognized in real time and can ask follow-up questions answered in English or Arabic. The work addresses three problems specific to in-gallery deployment: fine-grained visual similarity among 51 catalogued artifacts (many near-identical Ramesside statues), the gap between curated training data and handheld camera conditions, and the risk of an AI guide stating unsupported historical facts. Two engineering contributions are reported. First, an on-device artifact detector was developed through a data-quality-driven iteration study -- from foundation-model auto-annotation (YOLO-World), through spatial label-cleaning rules, to a fully hand-annotated dataset -- isolating label quality as the decisive factor: the final YOLOv8n model resolves every previously failing class while remaining a 5.97 MB TensorFlow Lite asset that runs in real time on a mid-range phone ([email protected] = 0.995, [email protected]:0.95 = 0.924). Second, a bilingual Retrieval-Augmented Generation (RAG) guide, grounded in a 108-record ChromaDB knowledge base, was benchmarked across seven candidate language models, with Gemma 4 E2B (Q4 K M) selected; ten targeted optimizations reduce end-to-end latency from over 30 s to approximately 10 s.

Zero-Shot Captioning for Cultural Heritage: Automated Image Analysis of Traditional Indonesian Clothing

文化遗产的零样本图像描述:传统印尼服装的自动图像分析
Yotolembah, Anugrah Aidin, Yudistira, Novanto, Setyawan, Gembong Edhi
Abstract
This paper presents Custom ZeroCLIP, a retrieval-augmented vision-language framework for zero-shot captioning of Indonesian traditional garments. The dataset contains 3,800 expert-annotated images from all 38 Indonesian provinces. Using a province-level inductive zero-shot protocol, the model is trained on 24 seen provinces, validated on 6 seen provinces, and evaluated on 8 unseen provinces. The framework combines a frozen CLIP ViT-B/32 image encoder, a CLIP text encoder, a BERT text encoder, and an LSTM caption decoder. During inference, unseen-province labels and captions are unavailable, and retrieval uses only captions from training provinces. No unseen-province image, label, or caption is used during training, validation, or retrieval-bank construction. Custom ZeroCLIP achieves a CLIPScore of 0.8536, BLEU-4 of 0.3342, and METEOR of 0.4859, outperforming existing baselines. Ablation results show that retrieval improves cultural vocabulary recovery with a 19.3\% METEOR gain, while human evaluation confirms stronger cultural accuracy and fluency. The results demonstrate the effectiveness of retrieval-augmented domain adaptation for culturally grounded caption generation in low-resource heritage settings. The dataset is publicly available at https://github.com/AnugrahAidinYotolembah/Traditional-Indonesian-Clothing-Captioning-Dataset.

Cross-Modal Masked Compositional Concept Modeling for Enhancing Visio-Linguistic Compositionality

跨模态掩蔽组合概念建模以增强视觉-语言组合性
Li, Wei, Huang, Zhen, Tian, Xinmei
Abstract
Contrastively trained vision-language models like CLIP, have made remarkable progress in learning joint image-text representations, but still face challenges in compositional understanding. They often exhibit a "bag-of-words" behavior--struggling to capture the object relations, attribute-object bindings, and word order dependencies. This limitation arises not only from the reliance on global, single-vector representations for optimization, but also from the insufficient exploitation and modeling of the rich compositional information inherently present in paired image text data. In this work, we propose MACCO (MAsked Compositional Concept MOdeling), a framework that masks compositional concepts in one modality and reconstructs them conditioned on the full contextual information from the other, enabling the model to capture and align cross-modal compositional structures more effectively. To facilitate this process, we introduce two auxiliary objectives that jointly align and regularize masked features both inter-modally and intra-modally. Extensive experiments on five compositional benchmarks, along with in-depth analyses, demonstrate that our approach not only significantly enhances compositionality in VLMs but also improves their ability to capture syntactic structure and linguistic information. Additionally, the improved compositionality also benefits text-to-image generation and multimodal large language model. Code is available at https://github.com/hiker-lw/MACCO.

对比训练的视觉-语言模型,如CLIP,在学习联合图像-文本表示方面取得了显著进展,但在组合理解上仍面临挑战。它们常常表现出“词袋”行为——难以捕捉对象关系、属性-对象绑定和词序依赖。这一局限性不仅源于对全局单向量表示的优化依赖,还源于对成对图像文本数据中固有的丰富组合信息的不足利用和建模。在本研究中,我们提出了MACCO(掩蔽组合概念建模)框架,该框架在一种模态中掩蔽组合概念,并基于另一种模态的完整上下文信息重建它们,从而使模型能够更有效地捕捉和对齐跨模态组合结构。为促进这一过程,我们引入了两个辅助目标,这些目标共同对齐和正则化掩蔽特征,既在模态间也在模态内。对五个组合基准的广泛实验以及深入分析表明,我们的方法不仅显著增强了视觉-语言模型的组合性,还提高了它们捕捉句法结构和语言信息的能力。此外,改进的组合性还对文本到图像生成和多模态大型语言模型带来了好处。代码可在 https://github.com/hiker-lw/MACCO 获取。

Abstract
Holistic visual tokenizers are fundamental to unified multimodal models (UMMs) as they map diverse visual inputs into a unified representation space. In this paper, we present HYDRA-X, the first UMM that unifies image and video tokenization within a single Vision Transformer (ViT). Our design is driven by two core challenges: efficiently injecting spatiotemporal reconstruction capability into a native ViT, and embedding image- and video-level semantic awareness into the latent space. To address the first, comprehensive ablations reveal two key findings: (1) frame-level causal temporal attention suffices for visual reconstruction, whereas full spatiotemporal attention degrades it; and (2) hierarchical temporal compression substantially outperforms single-step alternatives. To tackle the second, we propose a lightweight decompressor that upsamples temporally compressed features under joint image-video teacher supervision, thereby enforcing complementary semantic structures within the compact latent space. Building on this holistic tokenizer, we further propose a principled improvement of the editing pipeline: source-target interaction should occur at the latent level inside the tokenizer rather than at the semantic level inside the LLM, substantially improving editing consistency and accelerating convergence. Instantiated at the 7B dense model, HYDRA-X achieves strong performance across image and video understanding and generation tasks, paving the way for future unified-tokenizer UMMs.

整体视觉标记器是统一多模态模型(UMMs)的基础,因为它们将多样的视觉输入映射到统一的表示空间。在本文中,我们提出了HYDRA-X,这是第一个在单一视觉变换器(ViT)中统一图像和视频标记化的UMM。我们的设计受到两个核心挑战的驱动:有效地将时空重建能力注入原生ViT,以及在潜在空间中嵌入图像和视频级别的语义意识。为了解决第一个问题,全面的消融实验揭示了两个关键发现:(1)帧级因果时序注意力足以用于视觉重建,而完整的时空注意力则会降低其效果;(2)层次时序压缩显著优于单步替代方案。为了解决第二个问题,我们提出了一种轻量级解压器,在联合图像-视频教师监督下对时序压缩特征进行上采样,从而在紧凑的潜在空间内强制执行互补的语义结构。在这一整体标记器的基础上,我们进一步提出了编辑流程的原则性改进:源-目标交互应在标记器内部的潜在层面进行,而不是在大型语言模型(LLM)内部的语义层面进行,从而显著提高编辑一致性并加速收敛。在7B密集模型中实例化的HYDRA-X在图像和视频理解及生成任务中表现出色,为未来的统一标记器UMMs铺平了道路。

DuET: Dual Expert Trajectories for Diffusion Image Editing

DuET:用于扩散图像编辑的双专家轨迹
Troeshestova, Lidia, Ustyuzhanin, Alexander, Kastryulin, Sergey
Abstract
Recent diffusion editors perform diverse instruction-based edits while conditioning on the source image at every denoising step. Yet persistent source-image conditioning can limit how fully an edit is executed and how natural the result appears, especially when the target scene diverges substantially from the input. We introduce DuET (Dual Expert Trajectories), a training-free inference method that temporarily relaxes source-image conditioning by transitioning through a text-to-image phase before returning to edit mode, allowing the denoising trajectory to move toward the target distribution while retaining the structural benefits of image-conditioned editing. Without modifying model weights or increasing sampling cost, DuET consistently improves instruction relevance, semantic fidelity, and perceptual quality across diverse models and benchmarks. In some cases, these gains come with a modest reduction in source-image preservation, revealing a predictable trade-off between source preservation and edit fidelity.

近期的扩散编辑器在每个去噪步骤中基于源图像执行多样的基于指令的编辑。然而,持续的源图像条件限制了编辑的执行程度和结果的自然性,尤其是在目标场景与输入有显著偏离时。我们提出了DuET(双专家轨迹),这是一种无训练推理方法,通过在返回编辑模式之前过渡到文本到图像的阶段,暂时放松源图像条件,从而允许去噪轨迹朝向目标分布移动,同时保留图像条件编辑的结构优势。在不修改模型权重或增加采样成本的情况下,DuET在多个模型和基准测试中持续改善了指令相关性、语义保真度和感知质量。在某些情况下,这些提升伴随着源图像保留的适度减少,揭示了源保留与编辑保真度之间的可预测权衡。

ReFree: Towards Realistic Co-Speech Video Generation via Reward-Free RL and Multilevel Speech Guidance

ReFree:通过无奖励强化学习和多层次语音指导实现逼真的共语视频生成
Mohamed, Salaheldin, Mughal, M. Hamza, Dabral, Rishabh, Theobalt, Christian
Abstract
Speech-driven talking character animation seeks to generate life-like portrait videos that convey natural conversation behavior, aligning facial motion with spoken audio. Although recent advances in video generation have substantially improved realism in video-based animation, achieving both accurate lip articulation and expressive behavior remains challenging. Existing approaches typically trade off precise phoneme-to-lip synchronization against dynamic facial expressions and head motion, yielding animations that are either accurate yet rigid, or expressive but poorly synchronized. We address this challenge by proposing ReFree-S2V, a flow-matching speech-to-portrait animation framework that builds upon a pretrained video generation model to achieve fine-grained speech articulation and high-level expressive cues in speech-driven portrait animation. This model introduces a multi-level speech representation capturing phonetic and prosodic information at both local and global granularities. These representations are selectively injected into transformer blocks via learnable level selectors, enabling both accurate lip synchronization and natural expressive motion. To achieve natural head movements, we further introduce a novel reward-free reinforcement learning scheme into flow-matching training to discourage perceptually implausible motion without relying on handcrafted synchronization metrics or reward models, or the high cost of human preference annotation. Extensive experiments demonstrate that ReFree-S2V achieves state-of-the-art performance, significantly outperforming existing methods in both quantitative lip-sync accuracy and qualitative human evaluations of naturalness and expressivity.

MagPlus: Bridging Micro-to-Regular Facial Expressions through Learnable Magnification

MagPlus:通过可学习的放大技术连接微表情与常规表情
Jammal, Sliman, Sharf, Andrei
Abstract
Facial micro-expressions are subtle and short-lived facial movements that provide important cues about genuine human emotions. However, modeling and generating them remains difficult because annotated micro-expression data is limited and the underlying facial motions are extremely weak. Existing micro-expression generation methods therefore often suffer from limited quality, weak robustness, and poor generalization. We propose MagPlus, a transferable micro-expression processing pipeline that connects micro-expression analysis with standard facial animation models. Instead of training a dedicated generator from scratch, MagPlus learns to magnify subtle facial motions into the range of regular facial expressions, transforming micro-expressions into signals that are compatible with existing facial expression processing models. The magnified sequence is then used by a standard facial expression model for tasks such as transfer and synthesis. A complementary DeMagPlus module then restores the generated motion back to realistic micro-expression intensity levels while preserving the synthesized dynamics. We evaluate the framework using four facial animation models: FOMM, FSRT, MetaPortrait, and EmoPortraits. None of these models are trained on micro-expression data. Experiments show that MagPlus-DeMagPlus enables pretrained macro-expression models to generate more realistic micro-expression motion without retraining the backbones.

Masked and Predictive Self-Supervised Foundation Models for 3D Brain MRI

用于3D脑部MRI的掩蔽与预测自监督基础模型
Ergün, Esra, Chandarana, Hersh, Sodickson, Dan, Ünal, Gözde
Abstract
Self-supervised foundation models have shown strong promise in medical imaging. However, existing MRI foundation-model studies have primarily emphasized segmentation and dense prediction tasks, while systematic investigation of self-supervised foundation models for MRI-based disease detection remains limited. In this work, we investigate two major self-supervised pretraining paradigms for MRI-based disease detection: reconstruction-based learning via Masked Autoencoders (MAE) and predictive representation learning via Joint Embedding Predictive Architectures (JEPA). We study the role of auxiliary objectives by introducing a novel spectral-domain reconstruction loss for MAE to enhance sensitivity to fine-grained anatomical structure, and by integrating variance--covariance regularization (VCR) within our JEPA framework to encourage decorrelated latent representations. Our models are pretrained on heterogeneous single-contrast MRI volumes in a contrast-agnostic setting, without modality concatenation. Across five downstream disease detection tasks, our results highlight the importance of self-supervised objective design for medical foundation model pretraining, demonstrating that the downstream benefit of each objective is determined by its relevance to the task's structure. Specifically, spectral regularization yields the largest improvements when the downstream discriminative signal is characterized by strong high-frequency anatomical structures, while covariance regularization is most beneficial when discriminative information spans multiple decorrelated feature dimensions. MAE with spectral-domain supervision consistently achieves superior downstream performance for MRI-based disease detection. These findings suggest that self-supervised objectives in medical imaging encode specific biases, and their downstream benefit is fundamentally conditioned on the task's structure.

OR-Action: Multi-Role Video Understanding with Fine-Grained Actions

OR-Action:多角色视频理解与细粒度动作
Tristram, Felix, Özsoy, Ege, Benz, Christian, Walch, Marcel, Ghazaei, Ghazal, Navab, Nassir
Abstract
Fine-grained understanding of operating room (OR) activity could enable workflow-aware assistance, yet remains difficult due to clutter, occlusions, and limited sensing. The prevailing approach to model this environment is scene graphs as an interpretable representation of OR interactions. Converting their frame-wise relational predictions into temporally extended, fine-grained actions however, is challenging without explicit temporal modeling. To enable a principled temporal evaluation of current OR understanding methods, we introduce the first action-centric benchmark built on a publicly available ego-exocentric OR dataset by defining a fine-grained, multi-role action taxonomy and generating dense action segments via distillation from ground-truth scene graph state changes. Experiments on this benchmark show that current scene graph prediction methods struggle to model temporal structure, even when adding explicit modeling through Graph Neural Networks. We therefore introduce a vision-only temporal model that outperforms graph-based methods significantly when using all available egocentric video as input. Building on this model we also introduce a novel multi- to single-view feature alignment strategy that improves single-view performance on multi-role action recognition, mitigating the need for extensive egocentric video capture. Benchmark and code will be released upon acceptance.

Dual-Domain Equivariant Generative Adversarial Network for Multimodal CT-PET Synthesis

用于多模态CT-PET合成的双域等变生成对抗网络
Steele, Gabriel, Altalib, Alzahra, Perelli, Alessandro
Abstract
We present a Dual-Domain Equivariant Generative Adversarial Network (DDE-GAN) for multimodal CT-PET image synthesis. Traditional GAN-based approaches often operate solely in the spatial domain and ignore geometric consistency, resulting in limited structural fidelity. DDE-GAN addresses these challenges by jointly learning from both spatial and frequency (Fourier) domains, capturing complementary anatomical and spectral information. Furthermore, rotational equivariance embedded in the physics of the CT and PET measurements are integrated into the loss of both the generator and discriminator to ensure consistent responses under rotations, improving anatomical accuracy. A hierarchical dual-domain training strategy enforces intra- and inter-domain consistency through multi-stage loss functions. Evaluated on the HECKTOR 2022 CT-PET dataset, DDE-GAN achieves superior synthesis quality over baseline models for CT-PET image synthesis. The results demonstrate that combining dual-domain learning with geometric equivariance substantially enhances multimodal image synthesis accuracy and robustness, enabling practical applications in PET completion and data augmentation.

JointEdit3D: Feed-Forward 3D Scene Editing in a Unified Latent Space

JointEdit3D:统一潜在空间中的前馈3D场景编辑
Zhu, Xinnan, Xu, Ruijie, Ying, Jiayu, Dong, Daoguo, Xu, Jiachen, Xie, Yuan, Tan, Xin
Abstract
Existing 3D scene editing methods typically rely on per-scene optimization over explicit 3D representations or cascaded edit-and-reconstruct pipelines, resulting in high test-time cost, limited 3D awareness, and structural inconsistencies. To couple appearance synthesis and geometry prediction during editing, we build on a unified RGB-geometry reconstruction-generation latent space and adapt it to feed-forward 3D scene editing. The resulting framework, \textbf{JointEdit3D}, performs asymmetric latent inpainting by observing only a single edited RGB reference latent and generating the remaining RGB views and edited geometry latent under source-scene anchoring. JointEdit3D introduces a dedicated SceneAnchor Branch to inject source-scene structure without forcing direct copying, and adopts edit/background-aware losses to balance edited-region fidelity with unedited-content preservation. To address the lack of paired resources for standardized 3D scene editing evaluation, we introduce SceneEdit3D-15K, a dataset with 15K paired editing samples and renderer-provided 3D annotations, together with SceneEdit3D-Bench, a curated 100-sample benchmark. Experiments show that JointEdit3D improves edited-region quality and 3D structural completeness over prior baselines while maintaining competitive background preservation.

Dual-Constrained Diffusion Image Compression for Operational Rate-Distortion-Perception Optimization

用于操作率-失真-感知优化的双约束扩散图像压缩
Jiang, Sanxin, Katto, Jiro, Sun, Heming
Abstract
The rate-distortion-perception (RDP) trade-off extends classical rate--distortion theory by imposing a distributional constraint on reconstructions, providing a unified framework for neural image compression that jointly governs fidelity and perceptual realism. While prior work achieves near-optimal rate--perception trade-offs, practical frameworks explicitly realizing the full RDP surface remain scarce, primarily due to the difficulty of introducing common randomness at the decoder. We propose DCIC (Dual-Constrained Diffusion Image Compression), which integrates a learned codec with a diffusion-based decoder governed by joint distortion and idempotence constraints. The distortion constraint bounds reconstruction fidelity relative to the base codec output; the idempotence constraint -- requiring that re-encoding the restored image recovers the base codec reconstruction -- serves as a tractable surrogate for the distributional perception requirement. Together, they steer the reverse denoising process via iterative optimization with consistent noise injection, realizing common randomness without additional rate overhead. At fixed rate, dual attenuation factors $(K_D, K_P)$ jointly navigate the Pareto frontier of the distortion-perception plane, enabling continuously adjustable fidelity-realism trade-offs from a single bitstream. DCIC$_{RD}$ ($K_P{=}0$) and DCIC$_{RP}$ ($K_D{=}0$) arise as boundary curves, with DCIC$_{RDP}$ ($K_D = K_P=1$) realizing the optimal interior operating point. Experiments on CelebA-HQ, CLIC2020, and ImageNet-1K across CNN, Transformer, and hybrid architectures confirm that DCIC$_{RDP}$ achieves superior BD-PSNR over all perceptual codecs, while DCIC$_{RP}$ matches dedicated perception-oriented methods in BD-FID, validating the practical value of full RDP surface navigation.

MoVerse: Real-Time Video World Modeling with Panoramic Gaussian Scaffold

MoVerse:基于全景高斯支架的实时视频世界建模
Zhou, Yang, Wang, Ziheng, Lu, Yuqin, Liu, Haofeng, Liang, Jun, He, Shengfeng, Li, Jing
Abstract
We present MoVerse, a real-time video world model that creates an interactively navigable scene from a single narrow-field-of-view image. This setting is challenging because the input observes only a small fraction of the environment, while interactive roaming requires a complete surrounding world, persistent geometry, controllable camera motion, and temporally coherent high-fidelity observations. MoVerse addresses this problem by separating world construction from observation rendering. It first expands the input into a gravity-aligned 360$^\circ$ panorama with topology-aware diffusion, closing the missing field of view before 3D reasoning. It then lifts the panorama into a persistent 3D Gaussian scaffold using panoramic geometry-aware residual prediction, yielding a dense and directly renderable spatial memory. Finally, a Gaussian-conditioned video renderer translates scaffold renderings along user-specified camera trajectories into photorealistic video. To make this renderer practical for interaction, we train a bidirectional diffusion teacher for high-quality conditional rendering and distill it into a causal autoregressive student for bounded-latency streaming. This design combines the controllability and long-range consistency of explicit 3D representations with the perceptual quality of generative video models.

我们提出了MoVerse,一种实时视频世界模型,它能够从单张狭窄视场图像创建一个可交互导航的场景。这个设置具有挑战性,因为输入仅观察到环境的一小部分,而交互漫游需要一个完整的周围世界、持久的几何结构、可控的相机运动和时间一致的高保真观察。MoVerse通过将世界构建与观察渲染分离来解决这个问题。它首先通过拓扑感知扩散将输入扩展为一个重力对齐的360$^ ext{°}$全景,填补缺失的视场,然后进行3D推理。接着,它利用全景几何感知的残差预测将全景提升为持久的3D高斯支架,从而产生一个密集且可直接渲染的空间记忆。最后,一个高斯条件视频渲染器沿用户指定的相机轨迹将支架渲染转换为照片级真实感视频。为了使该渲染器在交互中实用,我们训练了一个双向扩散教师以实现高质量的条件渲染,并将其提炼为一个因果自回归学生,以实现有限延迟的流媒体。这一设计结合了显式3D表示的可控性和长距离一致性与生成视频模型的感知质量。MoVerse在单个NVIDIA RTX~4090 GPU上支持以8 FPS的速度进行实时场景漫游,展示了通过单图像世界创建与交互视频输出的实用路径。

SmartFont: Dynamic Condition Allocation for Few-Shot Font Generation

SmartFont:用于少样本字体生成的动态条件分配
Yang, Zian, Wang, Zixin
Abstract
Few-shot font generation simultaneously requires global structural completeness and fine-grained local style fidelity. Existing methods usually either rely on global content-style modeling, which is robust but imperfectly disentangled, or emphasize component/local modeling, which captures fine details but relies heavily on local priors and reference coverage. We argue that the key challenge is not merely to learn purer conditions, but to organize complementary yet biased global and local conditions through multi-level allocation during generation. To this end, we propose SmartFont, a diffusion-based few-shot font generation framework that combines global content-style generation with weakly supervised local corrective experts. The local branch performs semantic-spatial allocation by learning expert-wise local concepts and semantically meaningful spatial maps under weak component supervision, enabling fine-grained correction without requiring explicit component-conditioned inference. On top of this, a denoising-state condition allocation module adaptively weights global content, global style, and local corrective feature across timesteps and injection blocks. Extensive experiments show that SmartFont achieves better global-local balance, improves glyph quality and local detail fidelity.

少样本字体生成同时需要全球结构的完整性和细粒度的局部风格保真度。现有的方法通常依赖于全球内容-风格建模,这种方法虽然稳健但分离效果不完美,或者强调组件/局部建模,这种方法捕捉细节但过于依赖局部先验和参考覆盖。我们认为,关键挑战不仅在于学习更纯的条件,而在于通过多层次分配在生成过程中组织互补但有偏的全球和局部条件。为此,我们提出了SmartFont,一个基于扩散的少样本字体生成框架,它结合了全球内容-风格生成与弱监督的局部校正专家。局部分支通过在弱组件监督下学习专家级局部概念和语义上有意义的空间图进行语义-空间分配,从而实现细粒度的校正,而无需显式的组件条件推断。在此基础上,一个去噪状态条件分配模块自适应地在时间步和注入块之间加权全球内容、全球风格和局部校正特征。大量实验表明,SmartFont在全球-局部平衡方面表现更佳,提高了字形质量和局部细节保真度。

Person Identification from Contextual Motion

基于上下文运动的人员识别
Kviatkovsky, Igor, Rivlin, Ehud, Shimshoni, Ilan
Abstract
We consider the problem of identifying people based on their motion styles. We present a generative model describing the action instance creation process and derive a probabilistic identity inference scheme for two common person identification scenarios motivated by the surveillance and authentication applications. We introduce a novel, \emph{interactive}, scenario for person identification from motion patterns. To this end, we formalize the identification process in the context of a sequential message exchange session between the subject and the system. The subject's behavior is modeled using a probabilistic generative model inspired by the Human Information Processing (HIP) paradigm. At each stage, the system presents a visual stimulus (a cue) to the subject and records their motion response. The cue is selected so as to maximize the mutual information of the expected response and the subject's identity. Once recorded, the response is used to update the a posteriori probability over possible subjects' identities. The process terminates once a sufficient classification confidence level is reached. To the best of our knowledge, this is the first time person identification is addressed in such interactive setting. We report high recognition rates on five publicly available datasets and our own novel dataset consisting of 4,476 recordings of 22 test subjects responding to 15 cues.

VietFashion: Benchmarking Sketch-Text Composed Image Retrieval for Cultural Outfits

VietFashion:文化服饰素描-文本组合图像检索基准
Cao, Hoang-Nguyen, Bui, Le-Hoang, Vo, Dinh-Khoi, Tran, Minh-Triet, Le, Trung-Nghia
Abstract
Cultural garments pose a unique challenge for visual retrieval systems, as their identity often depends on subtle structural and symbolic details that are poorly captured by standard AI models. We introduce VietFashion, a new benchmark for sketch-text composed image retrieval centered on the Ao Dai, a traditional Vietnamese garment. VietFashion enables designers and researchers to retrieve culturally meaningful outfits using a combination of hand-drawn sketches, which convey garment structure, and textual descriptions, which encode cultural semantics. The dataset is initialized with 650 sketches and expanded using generative models to produce over 21,000 photorealistic images with aligned captions. Textual prompts that describe detailed outfit attributes, which are extracted from fashion magazines to ensure authenticity and diversity. To better reflect the inherent ambiguity of design intent, VietFashion adopts a multi-target retrieval setting, where a single query may correspond to multiple valid results. We establish standardized evaluation protocols and benchmark state-of-the-art composed image retrieval methods. Experimental results reveal significant performance gaps in modeling fine-grained cultural semantics and multi-modal composition, positioning VietFashion as a challenging benchmark for fine-grained fashion retrieval. The dataset is publicly available at: https://hng0303.github.io/VietFashion.

OmniDirector: General Multi-Shot Camera Cloning without Cross-Paired Data

OmniDirector:无需交叉配对数据的通用多镜头相机克隆
Liu, Jiwen, Li, Shujuan, Fang, Zhixue, Li, Xiaohan, Zhou, Yan, Meng, Zijie, Zhang, Zhimin, Luo, Yawen, Zhang, Guoxin, Liu, Yu-Shen, Wan, Pengfei
Abstract
Cloning camera motion from reference videos is an important task in video generation, as videos provide intuitive and precise control. Existing methods either directly use parametric representations that fail to handle multi-shot generation or synthesize cross-paired data, which suffer from data scarcity, resulting in poor performance in complicated camera motion cloning. To address these issues, we introduce a general camera motion representation that encodes cameras as grid motion videos. This camera grid represents the camera parameters visually and supports the integration of diverse trajectories for multi-shot video generation. Building upon this, we propose OmniDirector, a unified framework trained on a million-scale camera grid-video pairs that coordinates characters, actions, and cameras to provide director-level control for multimodal diffusion transformers. Furthermore, we design a novel hierarchical prompt expansion agent that harmoniously integrates different control signals by systematically describing camera motion and visual content through understanding signal relationships. Extensive experiments demonstrate the superior performance and outstanding controllability of our framework. Project page: https://ymlinfeng.github.io/OmniDirector.github.io/

VISA: VLM-Guided Instance Semantic Auditing for 3D Occupancy World Models

VISA:基于VLM指导的3D占用世界模型实例语义审计
Xian, Ruiqi, Xian, Yuehan, Liang, Jing, Qi, Xuewei, Manocha, Dinesh
Abstract
Semantic 3D occupancy provides a voxelized world state for autonomous driving and robot decision making, but object and rare-class errors can affect free-space interpretation, collision checking, and temporal state propagation. We show that a common VLM strategy, aligning 3D voxel or object features with crop-caption embeddings, improves text-space similarity without reliably improving closed-set occupancy mIoU. Motivated by this mismatch, we propose VISA, a training-time semantic auditing approach for existing occupancy world models. VISA queries an offline VLM on a representative crop of each physical object instance, obtains a structured audit with class hypotheses, plausible confusions, reliability, attributes, and evidence, and propagates it along the object track. The audit is grounded to matched 3D object voxels and distilled into semantic logits through reliability-weighted taxonomy, attribute-factor, and scene-level audit graph losses, while inference remains unchanged and requires no VLM. On nuScenes, averaged across three runs, VISA improves OccWorld from 19.06 to 20.05 mIoU and GaussianWorld from 21.36 to 21.91 mIoU; on GaussianWorld, object mIoU improves from 18.18 to 19.16 and rare-class mIoU from 15.60 to 16.79. These results suggest that VLMs are better suited to closed-set occupancy as reliability-aware semantic auditors than as generic caption-embedding targets.

Point-Wise Geometry-Aware Transformer for Partial-to-Full Point Cloud Registration in Computer-Assisted Surgery

基于点的几何感知变换器用于计算机辅助外科中的部分到完整点云配准
Zhou, Siyu, Jiang, Zhongliang
Abstract
Partial-to-full registration remains challenging due to varying overlap ratios, fluctuating point densities, and the presence of noise. While transformers have shown strong potential for point cloud processing, prior methods typically confine them to global context aggregation, overlooking fine-grained local geometry crucial for accurate correspondence. We propose \emph{GAPR-Net}, a learning-based point cloud registration framework with a coarse-to-fine architecture that combines convolution and transformer modules, in which local and global information is fused between the partial and full point clouds using a cross-attention mechanism. To achieve this, a transformation-invariant point-wise geometric feature representation is proposed, which can robustly capture relative geometric features for individual points with respect to their neighboring points. To evaluate the effectiveness of the proposed approach, experiments are conducted on four geometrically distinct bones, including the tibia, femur, pelvis, and thoracic cartilage. The overall registration recall reaches 94.2\%, the method results in a low RMSE of 1.992 mm and $R^2$ values of 0.908 and 0.974 for rotation and translation, respectively. The results demonstrate that the proposed method effectively addresses the partial-to-full point cloud registration problem. The proposed method enables highly accurate 3D point cloud registration using partial observation, providing a critical foundation for precise surgical navigation and robotic interventions in computer-assisted surgery. The code will be accessed after the double-blind review process.

Budget-Constrained Step-Level Diffusion Caching

预算约束的分步级扩散缓存
Lei, Mingkun, Zhao, Tong, Yuan, Liangyu, Zhang, Chi
Abstract
Step-level caching accelerates diffusion models by exploiting temporal redundancy across denoising steps. Existing methods make per-step cache decisions using threshold-based heuristics, without directly optimizing for final output quality. As a result, their inference latency varies across inputs and is difficult to control at deployment. In this work, we propose BudCache, which inverts this formulation: rather than letting per-step error thresholds dictate the runtime cost, we fix the compute budget in advance and search for the cache policy that best preserves the final output. To tackle the combinatorial complexity of step selection, we combine Simulated Annealing with deterministic Hill Climbing. This offline search identifies high-quality cache policies within minutes and introduces no online search or thresholding overhead during inference. When the compute budget is very tight, we further introduce cache-aware schedule alignment, which adapts the time discretization to the selected cache policy to reduce cache-induced trajectory mismatch. Experiments on FLUX.1-dev and Wan2.1 show that BudCache achieves better generation quality than heuristic caching baselines under the same inference budgets. Code is available at https://github.com/Westlake-AGI-Lab/BudCache

分步级缓存通过利用去噪步骤中的时间冗余来加速扩散模型。现有方法使用基于阈值的启发式方法进行每一步的缓存决策,而没有直接优化最终输出质量。因此,它们的推理延迟在不同输入之间变化,并且在部署时难以控制。在本研究中,我们提出了BudCache,它颠覆了这种公式:与其让每一步的误差阈值决定运行成本,不如提前固定计算预算,并搜索最佳保留最终输出的缓存策略。为了应对步骤选择的组合复杂性,我们将模拟退火与确定性爬山算法相结合。这种离线搜索在几分钟内识别出高质量的缓存策略,并且在推理过程中不会引入在线搜索或阈值开销。当计算预算非常紧张时,我们进一步引入了缓存感知的调度对齐,它根据所选缓存策略调整时间离散化,以减少缓存引起的轨迹不匹配。在FLUX.1-dev和Wan2.1上的实验表明,BudCache在相同推理预算下实现了比启发式缓存基线更好的生成质量。代码可在 https://github.com/Westlake-AGI-Lab/BudCache 获取。

Heterogeneous LiDAR Early Fusion and Learned Re-Ranking Strategy for Robust Long-Term Place Recognition in Unstructured Environments

异构LiDAR早期融合与学习重排序策略在非结构化环境中实现稳健的长期地点识别
Vilella-Cantos, Judith, Cabrera, Juan José, Ballesta, Mónica, Valiente, David, Payá, Luis
Abstract
Robust localization in unstructured environments, such as agricultural fields, is a critical challenge for autonomous systems. LiDAR sensors provide detailed 3D information about the environment and are invariant to lighting conditions. For this reason, LiDAR-based place recognition methods have gained significant attention. In this paper, we propose MinkUNeXt-VINE++, a novel approach that combines early fusion of heterogeneous LiDAR data from two sensors (Livox Mid-360 and Velodyne VLP-16) and a learned re-ranking strategy in inference time. This fusion leverages the strengths of each sensor to provide a more comprehensive representation of the environment. Additionally, the re-ranking approach is particularly important in repetitive environments, such as vineyards, as finding true positives is a major challenge. We evaluated our approach using the TEMPO-VINE dataset, which provides heterogeneous LiDAR data in vineyard environments across different phenological stages. Our results demonstrate that MinkUNeXt-VINE++ significantly improves place recognition performance compared to single-sensor approaches and state-of-the-art methods. MinkUNeXt-VINE++ achieves a 20% improvement in the Recall@1 metric compared to single-sensor approaches, and +30% including re-ranking. The code of our method is publicly available for reproduction.

Measurement-Calibrated Multi-Camera Fusion for Vision-Based Indoor Localization

基于测量校准的多摄像头融合用于视觉室内定位
Diz, Mateo Toro, Hoss, Jonathan, Klarmann, Noah
Abstract
Indoor vision-based localization systems are affected by detection noise, occlusions, and limited camera coverage, leading to uncertainty at multiple stages of the pipeline. While multi-camera data fusion is widely used to mitigate these issues, it is typically treated as a black-box component and evaluated solely end-to-end, obscuring its mechanistic contributions. To address this gap, this work investigates whether explicitly characterizing single-camera localization errors can be leveraged to calibrate and optimize multi-camera data fusion. We introduce a measurement-calibrated fusion approach that integrates component-wise error quantification, specifically isolating homography calibration, human detection, and motion tracking. A component-wise evaluation is conducted to quantify error contributions from homography calibration, human detection, and motion tracking. Experimental results show that data fusion improves localization accuracy compared to single-camera baselines. While measurement-calibrated fusion provides only limited improvement in absolute accuracy over standard fusion, it substantially reduces trajectory variance and improves motion smoothness, which are critical for applications requiring stable and continuous motion estimates. These results highlight the value of explicit error characterization when designing data fusion strategies for vision-based indoor positioning systems.

MaskWAM: Unifying Mask Prompting and Prediction for World-Action Models

MaskWAM:统一掩码提示与预测的世界行动模型
Yu, Hanyang, Lin, Haitao, Zhang, Jingbo, Zhang, Wenyao, Gu, Chenghao, Li, Heng, Tan, Ping
Abstract
World Action Models (WAMs) present a promising paradigm for robotic control via video prediction. However, current WAMs suffer from fundamental spatial bottlenecks: standard text inputs introduce referential ambiguity in cluttered scenes, while unstructured RGB predictions lack semantic grounding and remain biased by task-irrelevant backgrounds. To overcome these limitations, we introduce MaskWAM, an object-centric world-action model. By jointly integrating masks as both explicit inputs and predictions via a unified Mixture of Transformers (MoT), MaskWAM unlocks robust policy generalization. This design provides two key benefits: (1) predicting future masks yields object-centric semantic supervision that suppresses visual noise, significantly enhancing even standard text-conditioned WAMs; and (2) coupling this predictive supervision with first-frame visual prompts, such as target object masks, establishes a precise spatial anchor that substantially reduces language ambiguity. Crucially, as WAMs are inherently vision-driven architectures, direct mask conditioning yields substantially stronger guidance than text alone, establishing a precise and robust paradigm for manipulating unseen objects. Evaluations on LIBERO, RoboTwin, and real-world tasks demonstrate that MaskWAM significantly outperforms baselines in both language-clear and language-ambiguous tasks.

What's Old is New Again: Classical Dimensionality Reduction for Efficient Saliency-Guided Biometric Attack Detection

旧的又是新的:用于高效显著性引导生物识别攻击检测的经典降维方法
Webster, Samuel, Scheirer, Walter
Abstract
Saliency-guided training is a paradigm in visual recognition that encourages models to focus on the most relevant image regions during learning. While its application in biometric presentation attack detection (PAD) has shown strong benefits in robustness and generalization, adoption is often limited by the high cost, domain specificity, and limited scalability of existing saliency acquisition methods, such as human annotations over a limited dataset. We present a novel, cost-efficient, and highly-scalable approach to saliency acquisition using maps inspired by classical dimensionality reduction techniques: PCA and LDA. Our proposed methods generate saliency maps directly from raw training data, requiring no human annotation nor domain knowledge. We contextualize the effectiveness of these saliency sources in three saliency-explored domains (iris PAD, synthetic face detection, fingerprint PAD) and demonstrate its scalability in two saliency-novel domains (fingerprint vein PAD and ID card PAD). Across all domains tested, models trained using dimensionality reduction-sourced saliency maps exceed baseline and sometimes SOTA saliency methods without any resource investment or domain-specific tooling. Our findings overcome an important yet unaddressed barrier to saliency-guided training for biometric attack detection and beyond.

Edit the Bits, Diff the Codes: Bitwise Residual Editing for Visual Autoregressive Models

编辑比特,差异编码:视觉自回归模型的比特残差编辑
Zhang, Shengqiang, Liao, Ruotong, Tresp, Volker, Plank, Barbara, Schütze, Hinrich
Abstract
Text-guided image editing with visual autoregressive (VAR) generators requires controlling both what the model samples and where the sampled change is written back into the image code. Existing VAR editors mainly operate on token streams, features, or flat next-token logits, leaving two native structures of bitwise-residual VAR models underused: the per-bit Bernoulli prediction head and the additive multi-scale residual code field from which the image is assembled. We propose BitResEdit, a training-free editor for bitwise-residual VAR generators such as Infinity. BitEdit performs source-negative guidance by tilting the post-CFG per-bit log-odds along a source--target contrast computed on a shared edited prefix, then projects each update into a closed-form Bernoulli-KL trust region around the clean CFG sampler. ResEdit converts the sampled bits into per-scale continuous-code residuals, gates them with a localization mask, and re-injects them through the generator's native sum-of-scales. Together they couple decision-time bit guidance with combination-time code composition, so masked-out latent features are preserved exactly by code arithmetic while localized, scale-aware edits are applied inside the target region. On PIE-Bench with Infinity-2B, BitResEdit attains the strongest text alignment among same-backbone VAR editors, improving CLIP on the edited region by +1.07 over the strongest prior editor while keeping background preservation competitive with it. Ablations show BitEdit and ResEdit play complementary roles in target alignment and background preservation.

Abstract
Purpose: To investigate whether contrast-informed data augmentation and domain-adversarial training improve the adult-to-neonatal generalization of the E2E-VarNet. Methods: Three training regimes were investigated: (1) adult-only training with unaugmented adult data, (2) mixed training with paired unaugmented and neonatal-informed augmented adult data, and (3) mixed training with a domain-adversarial objective. Models were trained on retrospectively undersampled multi-coil adult T2-weighted brain MR data and evaluated on neonatal and adult test data at acceleration factors $R=4$ and $R=8$ using quantitative metrics and qualitative evaluation. Feature analyses assessed whether domain-adversarial training altered the latent representations of unaugmented adult, augmented adult, and neonatal test samples. Results: Mixed training (Mixed) and mixed domain-adversarial training (Mixed-DAT) outperformed unaugmented adult-only training (Unaug-Only) when evaluated on neonatal data. At R=4, Mixed-DAT achieved the best performance (SSIM = 0.924 +/- 0.027, PSNR = 33.98 +/- 1.15 dB). At R=8, Mixed-DAT performed best when measured using SSIM (0.848 +/- 0.031 vs. 0.766 +/- 0.037 for Unaug-Only and 0.814 +/- 0.035 for Mixed) and Mixed performed best when measured using PSNR (29.56 +/- 0.83 dB vs. 26.26 +/- 0.78 dB for Unaug-Only and 29.43 +/- 0.83 dB for Mixed-DAT). Qualitative assessment of t-SNE plots suggested that Mixed-DAT increased the overlap among the latent representations of the unaugmented adult, augmented adult, and neonatal test data. Conclusion: Contrast-informed augmentation and domain-adversarial training improved adult-to-neonatal generalization of deep learning-based MR reconstruction. These findings suggest that contrast-informed data augmentation combined with adversarial training may improve robustness to domain shift in undersampled neonatal MR reconstruction.

EvTexture++: Event-Driven Texture Enhancement for Video Super-Resolution

EvTexture++:用于视频超分辨率的事件驱动纹理增强
Kai, Dachun, Lu, Jiayao, Zhang, Yueyi, Sun, Xiaoyan
Abstract
Event-based vision has drawn increasing attention owing to its distinctive properties, including ultra-high temporal resolution and extreme dynamic range. Recent works have introduced it to video super-resolution (VSR) to enhance flow estimation and temporal alignment. In contrast, this paper shifts the focus of event signals from motion refinement to texture enhancement in VSR. We propose EvTexture++, the first event-driven framework dedicated to texture enhancement in VSR. It leverages high-frequency spatiotemporal details from events to improve texture recovery. EvTexture++ incorporates a customized texture enhancement branch, along with an iterative texture enhancement module that progressively exploits high-temporal-resolution event information for texture restoration. This enables gradual refinement of texture regions across iterations, yielding more accurate and detailed high-resolution outputs. Besides intra-frame texture recovery, large motions could degrade inter-frame temporal consistency, particularly in texture regions, leading to texture flickering. To mitigate this, we further exploit the continuous-time motion cues of events to enhance temporal consistency, introducing a temporal texture alignment module that estimates event-guided texture-aware flow for precise inter-frame texture alignment. Moreover, EvTexture++ is designed as a plug-and-play tool to flexibly boost the performance of existing VSR models. Experiments on five datasets demonstrate that EvTexture++ achieves state-of-the-art performance. When integrated into recent VSR models, it yields significant improvements, with gains of up to 1.55 dB in PSNR on the texture-rich Vid4 dataset. Code: https://github.com/DachunKai/EvTexture.

基于事件的视觉因其独特的特性,如超高的时间分辨率和极大的动态范围,受到越来越多的关注。近期的研究将其引入视频超分辨率(VSR),以增强光流估计和时间对齐。与此不同,本文将事件信号的重点从运动细化转向VSR中的纹理增强。我们提出了EvTexture++,这是第一个专门用于VSR中纹理增强的事件驱动框架。它利用事件中的高频时空细节来改善纹理恢复。EvTexture++结合了一个定制的纹理增强分支,以及一个迭代纹理增强模块,逐步利用高时间分辨率的事件信息进行纹理恢复。这使得在迭代过程中逐渐细化纹理区域,从而产生更准确和详细的高分辨率输出。除了帧内纹理恢复外,大运动可能会降低帧间的时间一致性,特别是在纹理区域,导致纹理闪烁。为此,我们进一步利用事件的连续时间运动线索来增强时间一致性,引入一个时间纹理对齐模块,该模块估计事件引导的纹理感知光流,以实现精确的帧间纹理对齐。此外,EvTexture++被设计为一个即插即用的工具,以灵活提升现有VSR模型的性能。在五个数据集上的实验表明,EvTexture++达到了最先进的性能。当集成到近期的VSR模型中时,它带来了显著的改进,在纹理丰富的Vid4数据集上,PSNR提升高达1.55 dB。代码链接: https://github.com/DachunKai/EvTexture.

Towards Effective Waste Segmentation for Automated Waste Recycling in Cluttered Background

面向杂乱背景下自动化垃圾回收的有效垃圾分割
Javaid, Mamoona, Noman, Mubashir, Hannan, Abdul, Nawaz, Shah, Fiaz, Mustansar, Ghuffar, Sajid
Abstract
Rapid expansion of urban areas and population growth is causing an immense increase in waste production, which demands the need for efficient and automated waste management. In this scenario, automated waste recycling (AWR) using deep learning methods can assist humans in optimal waste management. Recent deep learning approaches for AWR provide promising waste segmentation performance, however, these methods rely on large backbone networks that are inefficient for AWR systems and suffer from performance deterioration in cluttered scenes. To this end, an optimal waste segmentation network is introduced which effectively utilizes the spatial domain to capture localized structural dependencies and the spectral domain to efficiently extract global contextual relationships. This cascaded design allows the network to progressively leverage both local and global representations across complementary domains to highlight the semantic information necessary for effective segmentation of various waste objects. Furthermore, auxiliary feature enhancement module (AFEM) is introduced to enhance the target objects' boundaries and blob amplification for better segmentation in cluttered scenarios. Extensive experimentation on ZeroWaste-aug, ZeroWaste-f and SpectralWaste datasets reveals the merits of the proposed method.

Revisiting Vehicle Color Recognition in Long-Tailed Surveillance Scenarios

重新审视长尾监控场景中的车辆颜色识别
Orrú, Vinícius, Foggiatto, Bruno H., Lima, Gabriel E., Menotti, David, Laroca, Rayson
Abstract
Vehicle color recognition is an important cue for vehicle identification in surveillance systems, especially when license plates are illegible due to low resolution, occlusion, motion blur, or poor illumination. However, real-world vehicle color distributions are highly imbalanced, making overall accuracy insufficient to assess performance on rare but operationally relevant colors. This paper presents a comprehensive study of vehicle color recognition under severe class imbalance using UFPR-VeSV, a challenging real-world surveillance dataset. We investigate synthetic minority-class augmentation through two off-the-shelf generative strategies: text-conditioned image generation with RunDiffusion/JuggernautXL and image-conditioned color editing with Gemini 2.0 Flash. The curated synthetic data are combined with modern visual representations, loss reweighting, learning-rate scheduling, color-safe augmentation, foreground-aware preprocessing, and ensemble fusion. The bestperforming approach achieves 94.6% micro accuracy and 79.7% macro accuracy, improving macro accuracy by 8.2 percentage points over recent literature. A manual error analysis further shows that many remaining failures are visually ambiguous even for human annotators, highlighting the practical limits of color-based vehicle identification in unconstrained surveillance imagery.

Surflo: Consistent 3D Surface Flow Model with Global State

Surflo:具有全局状态的一致性三维表面流模型
Guédon, Antoine, Nakamura, Shu, Dufour, Nicolas, Lei, Jiahui, Nishino, Ko, Kanazawa, Angjoo
Abstract
Geometry is invariant to viewpoint, which makes any collection of images a redundant encoding of a single 3D state. Existing feed-forward reconstruction models fail to exploit this: per-view methods emit overlapping, unaligned pointmaps that grow linearly with input count, while global-latent methods commit to a fixed, low-resolution output. We introduce Surflo, which compresses a variable number of unposed RGB views into K latent tokens-one global state-and decodes oriented 3D surface points by independently transporting them from noise onto the surface via flow matching. This frees the output from any fixed grid or token budget: the same latent yields from a few thousand to a million points in a single forward pass. To suppress the local inconsistencies inherent to independent per-point decoding, an inference-time guidance term correlates nearby points by injecting a photometric gradient during ODE integration. Surflo matches or surpasses feed-forward baselines on surface metrics, runs an order of magnitude faster than optimization-based methods that require hundreds of views, and is the only feed-forward approach to combine a global latent with arbitrary-resolution decoding.

几何形状对视角是不变的,这使得任何图像集合都是对单一三维状态的冗余编码。现有的前馈重建模型未能利用这一点:每视角方法产生重叠且未对齐的点图,且随着输入数量线性增长,而全局潜在方法则固定于低分辨率输出。我们提出了Surflo,它将可变数量的未定姿态RGB视图压缩为K个潜在标记——一个全局状态——并通过独立地将其从噪声传输到表面上,利用流匹配解码定向的三维表面点。这使得输出不受任何固定网格或标记预算的限制:相同的潜在标记在一次前向传递中可以产生从几千到一百万个点。为了抑制独立逐点解码固有的局部不一致性,在推理时引入的引导项通过在常微分方程(ODE)积分过程中注入光度梯度来关联附近的点。Surflo在表面度量上与前馈基线相匹配或超越,运行速度比需要数百个视图的基于优化的方法快一个数量级,并且是唯一将全局潜在与任意分辨率解码相结合的前馈方法。

World Tracing: Generative Pixel-Aligned Geometry Beyond the Visible

世界追踪:超越可见范围的生成像素对齐几何
Zhang, Hao, Banani, Mohamed El, Cheng, Jen-Hao, Zhang, Paul, Hua, Yi, Mildenhall, Ben, Lassner, Christoph, Ahuja, Narendra, Yang, Gengshan
Abstract
Image-to-3D methods often trade off faithfulness and completeness: depth estimators are anchored to input pixels but stop at the visible surface, while image-to-3D models generate complete shapes that are often misaligned with the input. We introduce World Tracing, a generative pixel-aligned geometry representation that predicts 3D points aligned with observed pixels while completing geometry beyond the visible surface. For each input pixel, World Tracing predicts an ordered stack of camera-space 3D points, where the first layer represents the visible surface and subsequent layers represent front-to-back intersections with occluded surfaces. We instantiate this representation with a world-tracing diffusion transformer, WT-DiT, which treats multiple geometry layers as separate denoising tokens coupled through factorized and global attention. WT-DiT is trained with pixel-space flow matching and a mixed noise schedule that balances visible-surface reconstruction with occluded-geometry generation. World Tracing achieves strong performance on visible-surface reconstruction and complete geometry generation across object, scene, and dynamic benchmarks, outperforming both depth predictors and image-to-3D generators. It also preserves 2D-to-3D correspondence, enabling text-driven 3D scene editing, geometry-conditioned novel-view video synthesis, and training-free integration with textured-mesh generators.

图像到三维的方法通常在真实感和完整性之间进行权衡:深度估计器锚定于输入像素,但仅停留在可见表面,而图像到三维模型生成的完整形状往往与输入不对齐。我们提出了世界追踪(World Tracing),一种生成的像素对齐几何表示,能够预测与观察到的像素对齐的三维点,同时在可见表面之外完成几何形状。对于每个输入像素,世界追踪预测一组有序的相机空间三维点,其中第一层表示可见表面,后续层表示与被遮挡表面的前后交点。我们使用世界追踪扩散变换器(WT-DiT)实例化这一表示,该变换器将多个几何层视为通过因子化和全局注意力耦合的独立去噪令牌。WT-DiT通过像素空间流匹配和混合噪声调度进行训练,以平衡可见表面重建与被遮挡几何生成。世界追踪在可见表面重建和完整几何生成方面在对象、场景和动态基准测试中表现出色,超越了深度预测器和图像到三维生成器。它还保持了二维到三维的对应关系,使得基于文本的三维场景编辑、几何条件的新视角视频合成以及与纹理网格生成器的无训练集成成为可能。

Flex4DHuman: Flexible Multi-view Video Diffusion for 4D Human Reconstruction

Flex4DHuman:用于4D人类重建的灵活多视角视频扩散
Cheng, Jen-Hao, Wang, Yipeng, Zhang, Hao, Yang, Gengshan, Hwang, Jenq-Neng
Abstract
We present Flex4DHuman, a multi-view video diffusion model that transforms a monocular or sparse multi-view video of a dynamic subject into synchronized dense multi-view videos using only relative camera-pose conditioning. Unlike prior human-centric methods that rely on skeletons, depth maps, normals, or rendered target-view geometry, Flex4DHuman requires no explicit geometry priors and instead conditions generation through relative camera-pose positional encoding. The generated videos can be directly ingested by downstream reconstruction pipelines to create dynamic 4D Gaussian splats. Built on the Wan 2.1 1.3B text-to-video model, Flex4DHuman preserves the backbone architecture and encodes camera and view information through a five-axis positional encoding that extends spatio-temporal RoPE with view indices and continuous SE(3) relative camera geometry. A three-stage curriculum progressively trains the model for pose following, flexible reference-to-target view generation, and temporal rollout. To support temporal rollout, we train with clean historical target-view tokens. We also add multi-view captions to enable test-time text control. Combined with an off-the-shelf 4D Gaussian Splatting stage, our framework lifts monocular static-camera videos into dynamic 4D Gaussian splats. Experiments on DNA-Rendering and ActorsHQ show that Flex4DHuman surpasses prior state-of-the-art methods, while the same formulation generalizes to animal categories after mixed human-animal training. These capabilities make Flex4DHuman a practical step toward scalable 4D content creation from casual monocular videos for simulation, gaming, AR/VR, and video re-shooting.

SpatialClaw: Rethinking Action Interface for Agentic Spatial Reasoning

SpatialClaw:重新思考代理空间推理的动作接口
Cho, Seokju, Hachiuma, Ryo, Badki, Abhishek, Su, Hang, Lee, Byung-Kwan, Song, Chan Hee, Liu, Sifei, Radhakrishnan, Subhashree, Kim, Seungryong, Wang, Yu-Chiang Frank, Chen, Min-Hung
Abstract
Spatial reasoning, the ability to determine where objects are, how they relate, and how they move in 3D, remains a fundamental challenge for vision-language models (VLMs). Tool-augmented agents attempt to address this by augmenting VLMs with specialist perception modules, yet their effectiveness is bounded by the action interface through which those tools are invoked. In this work, we study how the design of this interface shapes the agent's capacity for open-ended spatial reasoning. Existing spatial agents either employ single-pass code execution, which commits to a full analysis strategy before any intermediate result is observed, or rely on a structured tool-call interface that often offers less flexibility for freely composing operations or tailoring the analysis to each task. Both designs offer limited flexibility for open-ended, complex 3D/4D spatial reasoning. We therefore propose SpatialClaw, a training-free framework for spatial reasoning that adopts code as the action interface. SpatialClaw maintains a stateful Python kernel pre-loaded with input frames and a suite of perception and geometry primitives, letting a VLM-backed agent write one executable cell per step conditioned on all prior outputs, enabling the agent to flexibly compose and manipulate perception results and adapt its analysis to both intermediate text and visual observations and the demands of each problem. Evaluated across 20 spatial reasoning benchmarks spanning a broad range of static and dynamic 3D/4D spatial reasoning tasks, SpatialClaw achieves 59.9% average accuracy, outperforming the recent spatial agent by +11.2 points, with consistent gains across six VLM backbones from two model families without any benchmark- or model-specific adaptation.

空间推理,即确定物体的位置、它们之间的关系以及它们在三维空间中的运动能力,仍然是视觉-语言模型(VLMs)面临的基本挑战。工具增强代理试图通过将VLM与专业感知模块结合来解决这一问题,但它们的有效性受到调用这些工具的动作接口的限制。在本研究中,我们探讨了该接口的设计如何影响代理进行开放式空间推理的能力。现有的空间代理要么采用单次代码执行,这在观察到任何中间结果之前就承诺于完整的分析策略,要么依赖于结构化的工具调用接口,这往往在自由组合操作或根据每个任务调整分析时提供较少的灵活性。这两种设计在开放式、复杂的三维/四维空间推理中都提供了有限的灵活性。因此,我们提出了SpatialClaw,这是一个无训练的空间推理框架,采用代码作为动作接口。SpatialClaw维护一个状态保持的Python内核,预加载输入帧和一套感知与几何原语,使得基于VLM的代理能够在每一步根据所有先前输出编写一个可执行单元,从而灵活组合和操控感知结果,并将其分析适应于中间文本和视觉观察以及每个问题的需求。在涵盖广泛静态和动态三维/四维空间推理任务的20个空间推理基准测试中,SpatialClaw实现了59.9%的平均准确率,超越了最近的空间代理11.2个百分点,并在两个模型系列的六个VLM骨干网络中保持了一致的提升,而无需任何基准或模型特定的适应。

RepWAM: World Action Modeling with Representation Visual-Action Tokenizers

RepWAM:基于表示视觉-动作标记器的世界动作建模
Wang, Junke, Zhang, Qihang, Yang, Shuai, Luo, Yiming, Shen, Yujun, Wu, Zuxuan, Jiang, Yu-Gang, Xu, Yinghao
Abstract
This work presents RepWAM, a representation-centric world action model (WAM) built on representation visual-action tokenizers. Existing WAMs typically inherit reconstruction-oriented video tokenizers from pretrained video generation models. Although these tokenizers preserve visual fidelity, pixel reconstruction alone provides limited guidance for learning instruction-following dynamics that connect future prediction with robot control. To address this, we explore a semantic visual-action latent space for representation-centric world action modeling. Specifically, we train a representation visual-action tokenizer that maps visual inputs into aligned visual and latent action tokens. We then pretrain our WAM to jointly model future visual states and the latent actions that connect them under language instructions, followed by adaptation to real robot trajectories for closed-loop manipulation. Experiments on real-world manipulation tasks and simulation benchmarks show that RepWAM delivers strong performance across diverse manipulation settings, while ablations highlight the value of semantic visual-action tokenization over reconstruction-oriented alternatives. These results establish representation visual-action tokenization as a promising foundation for world action models and a step toward generalist robot policies. Code and weights will be available at https://github.com/wdrink/RepWAM.

Modality Forcing for Scalable Spatial Generation

可扩展空间生成的模态强制
Duisterhof, Bardienus Pieter, Ramanan, Deva, Ichnowski, Jeffrey, Johnson, Justin, Park, Keunhong
Abstract
Text-to-image (T2I) models contain rich spatial priors. Synthesizing photorealistic, cluttered scenes requires an understanding of geometry, including perspective and relative scale. Prior works adapt T2I models to leverage this prior for depth prediction, but they require dense depth data and involve complex recipes. We propose Modality Forcing, a simple, scalable post-training recipe for joint image-depth generation using a single DiT trained on sparse depth data. Modality Forcing enables conditional and joint generation of image and depth in any permutation by assigning separate noise levels per modality. Per-modality decoders let us train on sparse, real-world depth and achieve strong, generalizable depth prediction. We further show that Modality Forcing inherits the scalability of T2I pre-training: by training a set of T2I models from scratch (370M to 3.3B parameters), we find that larger models trained on more image data produce more accurate depth. Our strongest model is competitive with state-of-the-art monocular depth estimators and reduces AbsRel by 57% relative to existing joint image-depth generative models. These results provide strong evidence that image generation is a scalable pre-training objective for spatial perception. https://modality-forcing.github.io/

InterleaveThinker: Reinforcing Agentic Interleaved Generation

InterleaveThinker:增强代理交错生成
Zheng, Dian, Lee, Harry, Zhang, Manyuan, Feng, Kaituo, Guo, Zoey, Zhang, Ray, Li, Hongsheng
Abstract
Recent image generators have demonstrated impressive photorealism and instruction-following capabilities in single-image generation and editing. However, constrained by their architectures, they cannot achieve interleaved generation (text-image sequence), which has crucial applications in visual narratives, guidance, and embodied manipulation. Even the latest open-source Unified Multimodal Models (UMMs) exhibit limited performance in this regard. In this paper, we introduce InterleaveThinker, the first multi-agent pipeline designed to endow any existing image generator with interleaved generation capabilities. Specifically, we employ a planner agent to organize the image-text input sequence, instructing the image generator on the required execution at each step. Subsequently, we introduce a critic agent to evaluate the generator's outputs, identify samples that deviate from the planned instructions, and refine the instructions for regeneration. To implement this pipeline, we construct the Interleave-Planner-SFT-80k and Interleave-Critic-SFT-112k to perform a format cold-start. Then we develop Interleave-Critic-RL-13k to reinforce the step-wise instruction correction capability within a generation trajectory using GRPO. Since a single interleaved generation trajectory may involve over 25 generator calls, optimizing the entire trajectory is computationally impractical. Therefore, we propose accuracy reward and step-wise reward, allowing single-step RL to effectively guide the entire generation trajectory. The results show that InterleaveThinker improves performance across various image generators. On interleaved generation benchmarks, it achieves performance comparable to Nano Banana and GPT-5. Surprisingly, it also significantly enhances the base model on reasoning-based benchmarks; for example, on 4-step FLUX.2-klein, we observe substantial gains on WISE and RISE.

近期的图像生成器在单幅图像生成和编辑方面展示了令人印象深刻的照片真实感和遵循指令的能力。然而,由于其架构的限制,它们无法实现交错生成(文本-图像序列),而这在视觉叙事、指导和具身操作中具有重要应用。即使是最新的开源统一多模态模型(Unified Multimodal Models, UMMs)在这方面的表现也有限。在本文中,我们介绍了InterleaveThinker,这是第一个旨在赋予任何现有图像生成器交错生成能力的多代理管道。具体而言,我们采用一个规划代理来组织图像-文本输入序列,指导图像生成器在每一步所需的执行。随后,我们引入一个评估代理来评估生成器的输出,识别偏离计划指令的样本,并优化指令以进行再生成。为了实现这一管道,我们构建了Interleave-Planner-SFT-80k和Interleave-Critic-SFT-112k以执行格式冷启动。然后,我们开发了Interleave-Critic-RL-13k,以使用GRPO增强生成轨迹中的逐步指令修正能力。由于单个交错生成轨迹可能涉及超过25次生成器调用,因此优化整个轨迹在计算上是不切实际的。因此,我们提出了准确性奖励和逐步奖励,使单步强化学习能够有效指导整个生成轨迹。结果表明,InterleaveThinker在各种图像生成器上提高了性能。在交错生成基准测试中,它的表现可与Nano Banana和GPT-5相媲美。令人惊讶的是,它还显著提升了基础模型在基于推理的基准测试中的表现;例如,在4步FLUX.2-klein上,我们观察到在WISE和RISE上有显著的提升。

ToolSense: A Diagnostic Framework for Auditing Parametric Tool Knowledge in LLMs

ToolSense:用于审计大语言模型中参数化工具知识的诊断框架
Hathidara, Ashutosh, Sistla, Sai Shruthi, Schreiber, Sebastian, Bansal, Sahil
Abstract
Large language models deployed as agents over large tool catalogs face a critical tool-retrieval bottleneck. As embedding-based retrieval approaches rely on compact encoders that may under-capture specialized tool semantics, parametric tool retrieval addresses this by encoding each tool as a virtual token appended to the LLM vocabulary, fine-tuned in two stages (memorization then retrieval SFT) to use the LLM as a retriever, achieving strong performance on standard ToolBench retrieval benchmarks. Yet these benchmarks use verbose, fully-specified queries, and their evaluation applies constrained decoding that restricts outputs to valid token paths, neither reveals whether the model actually understands its tools. We introduce \textbf{ToolSense}, an open-source LLM-powered diagnostic framework that takes any tool catalog as input and automatically generates three benchmarks: a Realistic Retrieval Benchmark (RRB) with queries at three ambiguity tiers, an MCQ probing benchmark, and a QA probing benchmark. Applying ToolSense to ToolBench (~47k tools) and evaluating five parametric model training configurations reveals a knowledge-retrieval dissociation: on RRB queries, several configurations collapse by ~50-64 percentage points compared to fully-specified ToolBench benchmarks, falling below the embedding-model baseline. Additionally, despite strong retrieval performance, some models score near-random on factual probes, suggesting a knowledge-retrieval dissociation. We open-source the ToolSense framework and the ToolBench diagnostic benchmarks at https://github.com/SAP/toolsense.

作为代理部署在大型工具目录上的大语言模型面临着关键的工具检索瓶颈。由于基于嵌入的检索方法依赖于紧凑的编码器,这可能无法充分捕捉专业工具的语义,参数化工具检索通过将每个工具编码为附加到大语言模型(LLM)词汇表的虚拟标记来解决这一问题,经过两个阶段的微调(记忆和检索的监督微调)以使用LLM作为检索器,在标准的ToolBench检索基准上取得了良好的表现。然而,这些基准使用冗长的、完全指定的查询,并且它们的评估应用了受限解码,这限制了输出为有效的标记路径,未能揭示模型是否真正理解其工具。我们引入了 extbf{ToolSense},一个开源的LLM驱动的诊断框架,接受任何工具目录作为输入,并自动生成三个基准:一个具有三个模糊层次的现实检索基准(RRB)、一个多项选择题(MCQ)探测基准和一个问答(QA)探测基准。将ToolSense应用于ToolBench(约47,000个工具)并评估五种参数化模型训练配置揭示了知识检索的解离:在RRB查询上,与完全指定的ToolBench基准相比,几种配置的表现下降了约50-64个百分点,低于嵌入模型的基线。此外,尽管检索性能强劲,一些模型在事实探测上得分接近随机,表明存在知识检索的解离。我们在https://github.com/SAP/toolsense上开源了ToolSense框架和ToolBench诊断基准。

Arbor: Tree Search as a Cognition Layer for Autonomous Agents

Arbor:作为自主智能体认知层的树搜索
Prakriya, Neha, Hou, Chaojun, Gong, Zheng, Zhao, Huasha, Zhao, Xi, Li, Mou, Gu, Zhenyu, Barsoum, Emad
Abstract
Arbor is a multi-agent framework that introduces structured tree search as a cognition layer for autonomous agents operating in large, stateful action spaces. Prior autonomous optimization systems operate on isolated targets with stateless evaluation. Arbor instead maintains an explicit search tree of scored hypotheses that serves as the shared working memory across agents, evolving with every measurement, treating failures as diagnostic signal that reshapes subsequent exploration, and expanding as prior successes shift the bottleneck distribution. We validate Arbor on full-stack LLM inference optimization, a domain where achieving peak performance has historically required coordinated effort from engineering teams across the application, framework, compiler, kernel, and hardware stack. Arbor pairs an Orchestrator agent, which drives optimization by delegating to Domain Specialists across the inference stack, with a Critic agent that safeguards stability through root-cause analysis, introspection, and measurement validation -- a checks-and-balances architecture where neither agent can unilaterally drive the system. Agent capabilities are decomposed into hard skills (domain expertise) and soft skills (coordination protocols that determine how contributions compose), enabling fully autonomous multi-day campaigns. Arbor achieves up to 193% inference throughput-latency Pareto improvement over vendor-optimized baselines, while a single agent without the harness plateaus at +33% throughput improvement and crashes irrecoverably within hours. Arbor generalizes to multiple generations of hardware platform, and run-to-run variance is within 2 percentage points demonstrating that the method is hardware-agnostic and reproducible.

Strategic Decision Support for AI Agents

人工智能代理的战略决策支持
Kiyani, Shayan, Noorani, Sima, Pappas, George, Hassani, Hamed
Abstract
Traditionally, decision support studies how humans use machine learning models to make better decisions. In modern agentic systems, this division of roles is increasingly reversed: AI agents act on behalf of users, while humans and tools becomes support mechanisms around them. This role reversal brings reliability concerns to the forefront, since agentic errors can be consequential and agent behavior must remain aligned with human goals and constraints. Departing from the classical view of decision support, we revisit its two basic principles, the cost--value tradeoff of seeking support and the role of uncertainty quantification, in a setting where AI agents are the central actors. We propose a framework for strategic decision support for AI agents through an optimization problem that minimizes support usage subject to controlling a counterfactual missed-support error: the probability that the agent acts alone on instances where support would have materially improved its output. At the population level, we show that the optimal policy is a threshold rule on the value of support. Building on this structure, we develop an online algorithm that adaptively thresholds such a score and uses randomized exploration to control missed-support error without distributional assumptions. We further introduce a calibration-on-the-fly method that reduces unnecessary support calls online. We instantiate this framework across diverse scenarios, including information gathering, human--AI collaboration, and tool use, showing how each can be modeled through the same strategic decision-support lens. Experiments across these settings show that our method reliably controls the target error while substantially reducing support usage in practice.

传统上,决策支持研究人类如何利用机器学习模型做出更好的决策。在现代代理系统中,这种角色的分工正日益逆转:人工智能代理代表用户行动,而人类和工具则成为围绕它们的支持机制。这种角色的逆转将可靠性问题推向了前台,因为代理错误可能带来严重后果,代理行为必须与人类的目标和约束保持一致。我们从经典的决策支持视角出发,重新审视其两个基本原则:寻求支持的成本-价值权衡和不确定性量化的角色,在人工智能代理作为中心参与者的背景下。我们提出了一个针对人工智能代理的战略决策支持框架,通过一个优化问题来最小化支持使用,同时控制反事实未支持错误:即代理在本可以显著改善其输出的情况下单独行动的概率。在总体水平上,我们展示了最优策略是对支持价值的阈值规则。基于这一结构,我们开发了一种在线算法,该算法自适应地对该评分进行阈值处理,并利用随机探索来控制未支持错误,而无需分布假设。我们进一步引入了一种在线即时校准方法,以减少不必要的支持请求。我们在多种场景中实例化该框架,包括信息收集、人类-人工智能协作和工具使用,展示了如何通过相同的战略决策支持视角对每种情况进行建模。在这些设置中的实验表明,我们的方法可靠地控制了目标错误,同时在实践中显著减少了支持使用。

Pythagoras-Prover: Advancing Efficient Formal Proving via Augmented Lean Formalisation

毕达哥拉斯证明器:通过增强的 Lean 形式化推进高效的形式证明
Leang, Joshua Ong Jun, Zhao, Zheng, Stoian, Mihaela Cătălina, Xu, Qiyuan, Li, Haonan, Li, Wenda, Cohen, Shay B., Giunchiglia, Eleonora
Abstract
Modern Lean theorem provers achieve strong performance only with substantial training and inference compute, driven in part by scarce verified proof data and the long reasoning traces of formal proof search, making both supervised fine-tuning (SFT) and sampling expensive. We introduce Pythagoras-Prover, a compute-efficient open-source family of Lean theorem provers built for practical compute budgets. The family spans two generation paradigms: autoregressive models at 4B and 32B parameters, and a first proof-of-concept diffusion-based prover (4B) that iteratively refines Lean proofs at inference time. For training efficiency, we build a Lean-verified corpus stratified into easy, medium, and hard problems for curriculum SFT, so models acquire proof skills progressively from shorter, simpler proofs to longer, harder ones. During SFT, a dynamic proof-reasoning filtering scheme preserves informative proof traces while keeping each instance within an 8k-token context budget. We also introduce Augmented Lean Formalisation (ALF), which expands scarce verified corpora into variants of formal statements, populated via self-distillation for extra training signal without formally verifying every mutated instance. By perturbing known problems while preserving their formal character, ALF reduces reliance on any statement's surface form. Empirically, Pythagoras-Prover-4B surpasses DeepSeek-Prover-V2-671B at pass@32 on MiniF2F-Test (86.1% vs 82.4%) with ~167x fewer parameters, while Pythagoras-Prover-32B sets the open-source state of the art at 93.0% on MiniF2F-Test and solves 93 of 672 PutnamBench problems. We release MiniF2F-ALF, an ALF-mutated contamination-sensitive benchmark on which every evaluated model loses accuracy; here our 32B remains strongest and our 4B matches the prior state of the art, Goedel-Prover-V2-32B.

现代 Lean 定理证明器只有在大量训练和推理计算的支持下才能实现强大的性能,这在一定程度上是由于稀缺的经过验证的证明数据和形式证明搜索的长推理轨迹,使得监督微调(SFT)和采样都变得昂贵。我们引入了毕达哥拉斯证明器(Pythagoras-Prover),这是一个计算高效的开源 Lean 定理证明器系列,旨在适应实际计算预算。该系列涵盖了两种生成范式:具有 40 亿和 320 亿参数的自回归模型,以及一个首个基于扩散的概念验证证明器(4B),该证明器在推理时迭代地细化 Lean 证明。为了提高训练效率,我们构建了一个经过 Lean 验证的语料库,按简单、中等和困难问题分层,以便进行课程式 SFT,使模型能够逐步从较短、简单的证明获得证明技能,过渡到较长、困难的证明。在 SFT 过程中,动态证明推理过滤方案保留了信息丰富的证明轨迹,同时将每个实例保持在 8k 令牌的上下文预算内。我们还引入了增强的 Lean 形式化(Augmented Lean Formalisation, ALF),它通过自蒸馏扩展了稀缺的经过验证的语料库,生成形式声明的变体,以提供额外的训练信号,而无需对每个变异实例进行正式验证。通过扰动已知问题,同时保持其形式特征,ALF 减少了对任何声明表面形式的依赖。从经验上看,毕达哥拉斯证明器-4B 在 MiniF2F-Test 上以 86.1% 的通过率超过了 DeepSeek-Prover-V2-671B(82.4%),且参数数量少了约 167 倍,而毕达哥拉斯证明器-32B 在 MiniF2F-Test 上设定了开源领域的最新记录,达到了 93.0%,并解决了 672 个 PutnamBench 问题中的 93 个。我们发布了 MiniF2F-ALF,这是一个 ALF 变异的污染敏感基准,在该基准上每个评估模型的准确性均有所下降;在这里,我们的 32B 仍然是最强的,而我们的 4B 则与之前的最新技术 Goedel-Prover-V2-32B 相匹配。

PersonaDrive: Human-Style Retrieval-Augmented VLA Agents for Closed-Loop Driving Simulation

PersonaDrive:用于闭环驾驶仿真的人类风格检索增强VLA代理
Srewa, Mahmoud, Iddamsetty, Praneetsai, Faruque, Mohammad Abdullah Al, Elmalaki, Salma
Abstract
Closed-loop driving simulators typically populate their environments with non-ego traffic agents that behave largely the same way, produced either by rule-based traffic managers or by learned models trained toward a single behavioral mode. Recent work introduces style variation through post-hoc labels on observational data or LLM-inferred reward weights, but these signals act as proxies for what a style should reward rather than demonstrations of humans explicitly asked to drive in that style. We introduce PersonaDrive, a pipeline that conditions a vision-language-action (VLA) driving agent on retrieved demonstrations from a style-instructed human driving dataset, in which participants drive CARLA leaderboard routes under aggressive, neutral, and conservative instructions on a driver-in-the-loop rig. The pipeline has three stages: (i) offline triplet mining over per-style human driving data using a combined image-text similarity score; (ii) training a lightweight retrieval head that fuses frozen visual features with a small control encoder over per-style databases; and (iii) fine-tuning a single VLA backbone to treat retrieved context points as in-context behavioral demonstrations during waypoint prediction. At inference, the same backbone is conditioned on any style by swapping which per-style database the retrieval head queries, so selecting a style requires no per-style retraining while enabling human-style, style-diverse non-ego agents for closed-loop simulation. On Bench2Drive, PersonaDrive (no style) improves the driving score by 4.6% over SimLingo and 2.5% over HiP-AD, and under style conditioning attains the highest driving score in every style within a roughly 2% band (its weakest style surpassing the strongest baseline, DMW, by 5.4%), while average speed and acceleration rise by 18% and 25% from the conservative to the aggressive instruction.

"Did you lie?" Evaluating Lie Detectors across Model Scale and Belief-Verified Model Organisms

你在说谎吗?评估不同模型规模和信念验证模型生物的谎言检测器
Cooney, Alan, Africa, David, Irving, Geoffrey
Abstract
Robust lie detectors for language models could enable powerful techniques for auditing, monitoring, and post-hoc investigation of model behaviour, but evaluating them requires testbeds where models verifiably believe the opposite of what they say. We show that existing trained model organisms often fail this requirement, leaving prior positive and negative detection results difficult to interpret. We address this with 13 reasoning model organisms whose hidden beliefs are verified in chain-of-thought and shown to generalise to held-out tasks, alongside Varied Deception, a prompted-lying testbed covering a broad range of lie-inducing motivations. On these testbeds we evaluate four detectors: a chain-of-thought judge, a logprob classifier, and two activation probes, including Did-You-Lie (DYL), a new method for training follow-up probes. On prompted lying, across 31 open-weight models spanning 2B to 1T parameters, all four detectors show positive scaling with model capability. However, every activation- and logprob-based detector drops sharply on our trained model organisms, with DYL retaining the most signal; only the chain-of-thought judge remains strong, with 0.82 balanced accuracy, partly as an artefact of our verification process favouring CoT-readable beliefs. Current lie detectors therefore cannot support high-confidence claims about model beliefs, and we suggest research directions that may address some of their current limitations. We release our datasets, model organisms, and trained detectors.

TrajGenAgent: A Hierarchical LLM Agent for Human Mobility Trajectory Generation

TrajGenAgent:一种用于人类移动轨迹生成的分层大型语言模型代理
Li, Siyu, Tran, Toan, Zhao, Lingyi, Shafique, Khurram, Xiong, Li
Abstract
Human mobility data is important for transportation, urban planning, and epidemic control, but large-scale trajectory collection is often costly and privacy-constrained, motivating realistic synthetic trajectory generation. Existing LLM-based generators typically rely on either prompt engineering, which preserves zero-shot reasoning but lacks fine-grained spatiotemporal grounding, or trajectory-level fine-tuning, which improves statistical precision but incurs substantial computational cost and may weaken general reasoning. We propose TrajGenAgent, a semantic-aware hierarchical LLM-agent framework for human mobility trajectory generation without model fine-tuning. TrajGenAgent uses a two-stage orchestrator-worker design: an LLM first synthesizes an individual- and weekday-conditioned activity chain from historical evidence via in-context learning, and a deterministic workflow then grounds each activity into a complete visit using personalized POI retrieval, distance-aware location selection, kinematics-aware travel-time propagation, and LLM-based duration estimation. To evaluate realism beyond aggregate spatiotemporal statistics, we introduce an anomaly-detection-based evaluation framework using two complementary detectors to assess behavioral and semantic plausibility. Experiments on benchmark and large-scale simulation datasets show that TrajGenAgent improves spatiotemporal fidelity, semantic coherence, and individual-specific behavioral realism over representative neural and LLM-based baselines, while avoiding parameter updates.

人类移动数据对于交通、城市规划和疫情控制至关重要,但大规模轨迹收集往往成本高昂且受到隐私限制,这促使了现实合成轨迹的生成。现有的基于大型语言模型(LLM)的生成器通常依赖于提示工程,这保留了零样本推理但缺乏细粒度的时空基础,或轨迹级别的微调,这提高了统计精度但带来了巨大的计算成本,并可能削弱一般推理能力。我们提出了TrajGenAgent,一种语义感知的分层LLM代理框架,用于人类移动轨迹生成,无需模型微调。TrajGenAgent采用两阶段的协调者-工作者设计:LLM首先通过上下文学习从历史证据中合成个体和工作日条件下的活动链,然后一个确定性的工作流程将每个活动基于个性化的兴趣点(POI)检索、距离感知的位置选择、运动学感知的旅行时间传播和基于LLM的持续时间估计, grounding为完整的访问。为了在聚合时空统计之外评估现实性,我们引入了一种基于异常检测的评估框架,使用两个互补的检测器来评估行为和语义的合理性。在基准和大规模模拟数据集上的实验表明,TrajGenAgent在时空保真度、语义一致性和个体特定的行为现实性方面优于代表性的神经网络和基于LLM的基线,同时避免了参数更新。

Evoflux: Inference-Time Evolution of Executable Tool Workflows for Compact Agents

Evoflux:可执行工具工作流的推理时演化用于紧凑型智能体
Bhandari, Kushal Raj, Yue, Ling, Ko, Ching-Yun, Patel, Dhaval, Pan, Shaowu, Chen, Pin-Yu, Gao, Jianxi
Abstract
Compact language models (LMs) reduce cost, latency, and deployment risk for tool agents. Yet MCP-style tool use requires more than isolated function calling: an agent must discover tools from live catalogs, satisfy schemas, preserve dependencies across intermediate outputs, and ground final responses in executed evidence. Small planners often generate plausible workflow graphs that fail under tool resolution, parameter validation, dependency tracking, or execution. We argue that this failure mode is poorly handled by small-corpus distillation. A few hundred teacher traces can teach workflow format, but rarely cover the recovery behavior needed to repair failed plans over changing tool catalogs. We introduce Evoflux, an inference-time evolutionary search method that treats compact tool use as the repair of executable tool workflows. It evolves typed workflow graphs through structured edits, execution feedback, adaptive intensity, meta-guided redesign, and diversity pruning. On held-out MCP-Bench tasks spanning live MCP servers and 250 tools, Evoflux raises execution feasibility from roughly 3% to 17-24% across small planners. In contrast, SFT and SFT+DPO on the same search-mined data match, underperform, or collapse below zero-shot performance; ReAct reaches higher peaks, but with higher variance and token cost. These results show that execution-grounded search is more reliable under scarce teacher-trace budgets.

紧凑型语言模型(LMs)降低了工具智能体的成本、延迟和部署风险。然而,MCP风格的工具使用不仅仅需要孤立的函数调用:智能体必须从实时目录中发现工具,满足模式,保持中间输出之间的依赖关系,并在执行证据中扎根最终响应。小型规划器通常生成在工具解析、参数验证、依赖追踪或执行方面失败的合理工作流图。我们认为,这种失败模式在小语料库蒸馏中处理得很差。几百个教师轨迹可以教授工作流格式,但很少涵盖在变化的工具目录中修复失败计划所需的恢复行为。我们引入了Evoflux,这是一种推理时的进化搜索方法,将紧凑型工具使用视为可执行工具工作流的修复。它通过结构化编辑、执行反馈、自适应强度、元引导重设计和多样性修剪来演化类型化工作流图。在涵盖实时MCP服务器和250个工具的保留MCP-Bench任务中,Evoflux将执行可行性从大约3%提升到17-24%在小型规划器中。相比之下,SFT和SFT+DPO在相同的搜索挖掘数据上匹配、表现不佳或低于零-shot性能;ReAct达到更高的峰值,但伴随着更高的方差和标记成本。这些结果表明,在稀缺的教师轨迹预算下,基于执行的搜索更为可靠。

Abstract
Over the last decade, building human-level artificial general intelligence has moved from far-fetched speculation to being a concrete next-decade target for many of the largest AI organisations. Achieving this goal would have profound and far-reaching impacts on human society, which raises many complex questions for the decade ahead. This report investigates how AI itself might continue to develop in a post-AGI world along the continuum of machine intelligence. The endpoint of this continuum, Universal AI, is theoretically well understood, which provides some formal grounding for the main focus of this report: the transition from human-level AGI to artificial general superintelligence, which, intuitively, can be understood as a system that is more intelligent and cognitively capable than large organisations of humans. After characterizing ASI, the report discusses four potential pathways from AGI to ASI: scaling AGI, AI paradigm shifts, recursive improvement, and ASI emerging from large-scale multi-agent collectives. The report then discusses possible frictions and bottlenecks along these pathways. Determining whether the impact of these frictions will be negligible or substantial raises a number of concrete open research questions. Due to large uncertainties for predicting ASI progress, it cannot be ruled out that AI progress might continue to accelerate over the next years. This could imply that the image of a single transformative step change, caused by the introduction of human-level AGI into our society, could be inaccurate. More apt might be the prospect of a series of transformative societal changes caused by AI-enabled progress and breakthroughs across many areas of science and technology. Preparing for this prospect requires a massively interdisciplinary endeavour of global scope and interest.

Deployment-Centered Evaluation: Predicting Query-Level Rejection Risk in a Clinical LLM System

以部署为中心的评估:预测临床大语言模型系统中的查询级拒绝风险
Unell, Alyssa, Fuentes, Miguel, Li, Brenna, Lin, Bridget, Jagadeesan, Meena, Koyejo, Sanmi, Shah, Nigam
Abstract
Large language models (LLMs) are increasingly integrated into clinical systems, making it essential to evaluate the real-world utility of these systems. However, static benchmarks tend to measure correctness rather than user acceptance, aggregate performance across queries, and require densely annotated datasets -- leading to major blind spots for evaluating clinical systems. In this work, we perform a deployment-centered evaluation of an LLM system embedded within electronic health records at an academic medical center, where user feedback is sparse but closely reflects the deployment conditions. Specifically, we train a pre-response classifier that estimates the risk that a future interaction will result in the user rejecting the LLM response, based on query content and deployment-specific context available before generation. We conduct a prospective analysis of our model over 4.5 months of user feedback, finding that our prediction model achieves an AUROC of 0.719. Further, we estimate the benefit of such predictions in two downstream use cases (guardrail triggering and abstention). Our key conceptual insight is that making use of deployment-specific context (i.e., the provider type, department name, language model used for response), as opposed to only query content, improves the ability to predict whether the user will reject the system output. Altogether, our empirical case study demonstrates the feasibility of predicting user rejection using deployment-specific context, opening the door to targeted guardrails.

大型语言模型(LLMs)正越来越多地融入临床系统中,因此评估这些系统在现实世界中的实用性变得至关重要。然而,静态基准往往侧重于测量正确性而非用户接受度,跨查询的整体性能表现,以及需要密集标注的数据集,这导致了评估临床系统时的重大盲点。在本研究中,我们对嵌入在学术医疗中心电子健康记录中的LLM系统进行了以部署为中心的评估,在该环境中,用户反馈稀少但与部署条件密切相关。具体而言,我们训练了一个预响应分类器,该分类器根据查询内容和生成前可用的特定部署上下文,估计未来交互中用户拒绝LLM响应的风险。我们对模型进行了为期4.5个月的用户反馈前瞻性分析,发现我们的预测模型达到了0.719的AUROC。此外,我们还估计了这种预测在两个下游用例中的益处(防护触发和弃权)。我们的关键概念洞察是,利用特定部署上下文(即提供者类型、部门名称、用于响应的语言模型),而不仅仅是查询内容,可以提高预测用户是否会拒绝系统输出的能力。总体而言,我们的实证案例研究展示了利用特定部署上下文预测用户拒绝的可行性,为有针对性的防护措施开辟了新的可能性。

Definitional alignment before capability alignment: a Design-Science framework for adjudicating claims about AGI

能力对齐之前的定义对齐:一个用于裁定关于人工通用智能(AGI)主张的设计科学框架
Briones, J. E. Aguilera
Abstract
Claims that artificial general intelligence has already arrived and claims that it remains decades away are often defended from overlapping evidence. "AGI" lacks a single shared and stable referent and competing operationalizations can return different verdicts on the same system. This article treats that under-specification as a design and governance problem. Following Design Science Research Methodology, it develops DAF-AGI, a second-order conceptual artifact with two coupled components: five ordinal criteria for assessing the adjudicative fitness of candidate definitions and a structured governance audit of authorship, interest, certification, external verification and revision authority. The artifact is demonstrated on five prominent measurement families and one deflationary boundary position in a documented corpus and then stress-tested against a stylized strong arrival claim: that current generative systems constitute AGI because they outperform a well-educated adult on many cognitive tasks. On evidence from the cited 2024-2025 sources, the claim was certifiable only under a performance-based operationalization; capability-ontology, psychometric and skill-acquisition approaches did not certify it, the economic family remains indeterminate and the deflationary position refuses binary adjudication. The contribution is a novel integration and operationalization, not an empirical validation: independent application, inter-rater testing and author-external cases remain necessary.

The Theory of Mind Utility: Formal Specification of a Mentalizing Mechanism

心智理论效用:心智化机制的形式化规范
Gurney, Nikolos, Marsella, Stacy
Abstract
Inferring others' beliefs requires more than reading surface signals; it requires tracking who told them what, in what order, and how credibly. The Theory of Mind Utility (ToM-U) formalizes this epistemic state inference problem at the computational level of analysis, specifying what mentalizing computes and why without commitment to algorithmic or neural implementation. ToM-U achieves this by constructing Local Epistemic World Models (LEWMs) -- directed typed graphs that represent agents, state nodes, and the epistemic relationships among them -- and evaluating discrete candidate LEWMs against observed behavior until one achieves sufficient confidence. Five formal definitions specify the LEWM structure, agent node properties including ordered information access history, a bounded proliferation mechanism for recursive mentalizing, three inference procedures, and a residue function that captures the structured trace left by failed mentalizing attempts. ToM-U differs from Bayesian Theory of Mind and adjacent formal accounts, which presuppose rather than derive belief states, and from simulation theory and theory-theory, which lack a formal apparatus for epistemic state inference. The architecture generates directional, falsifiable predictions about mentalizing failure that follow from structural properties of the model rather than auxiliary assumptions, and positions ToM-U as a domain-agnostic mechanism upstream of goal inference and other downstream social cognitive processes.

推断他人的信念不仅需要解读表面信号,还需要追踪谁在何时以何种可信度告诉他们什么。心智理论效用(Theory of Mind Utility, ToM-U)在计算分析的层面上形式化了这一认知状态推断问题,明确了心智化计算的内容及其原因,而不依赖于算法或神经实现的承诺。ToM-U通过构建局部认知世界模型(Local Epistemic World Models, LEWMs)来实现这一目标——这些有向类型图表示代理、状态节点及其之间的认知关系,并对观察到的行为评估离散候选LEWM,直到达到足够的置信度。五个形式定义规定了LEWM结构、代理节点属性(包括有序信息访问历史)、用于递归心智化的有界扩展机制、三种推理程序以及捕捉失败心智化尝试所留下的结构化痕迹的残余函数。ToM-U与贝叶斯心智理论及相关的形式化模型不同,后者假设而非推导信念状态;也与模拟理论和理论理论不同,后者缺乏用于认知状态推断的形式化工具。该架构生成关于心智化失败的方向性、可证伪的预测,这些预测源于模型的结构属性而非辅助假设,并将ToM-U定位为目标推断及其他下游社会认知过程的领域无关机制。

Rethinking Psychometric Evaluation of LLMs: When and Why Self-Reports Predict Behavior

重新思考大语言模型的心理测量评估:何时以及为何自我报告能够预测行为
Kocielnik, Rafal, Han, Pengrui, Song, Peiyang, Marmarelis, Myrl G., Debnath, Ramit, Mobbs, Dean, Anandkumar, Anima, Alvarez, R. Michael
Abstract
Anticipating LLM behavioral tendencies from low-cost psychometric probes is critical for safe deployment, but only if self-reports (SR) reliably predict behavior. Recent work documented substantial SR-behavior dissociation in LLMs, but relied on broad personality traits (Big 5) that predict specific behaviors weakly, even in humans. Furthermore, the isolation of conversational sessions combined with weak context matching left open whether LLMs truly lack coherence or whether the conditions needed to detect such coherence were not met. We contrast Big 5 with the Theory of Planned Behavior (TPB), which measures intention targeted to a specific behavior and predicts human behavior substantially better than broad traits. We run experiments across four behavioral tasks and 11 frontier LLMs, while also varying session context and identity induction. We find that SR-behavior coherence exists but is selective. 1) Within a shared conversation, the Theory of Planned Behavior reaches human-level coherence; Big 5 does not. 2) Across separate conversations, coherence survives only for behaviors anchored outside the immediate prompt, such as implicit bias shaped by training, and collapses when behavior is strongly primed by context, as with sycophancy. 3) Persona prompting makes self-reports more consistent across conversations, but does not bring behavior into alignment. These findings suggest that coarse personality frameworks, such as Big 5 may not be the best tools for testing deployment behavior. More task- and behavior-specific instruments are needed, and even these must be evaluated across tasks and contexts.

从低成本的心理测量探针中预测大语言模型(LLMs)的行为倾向对于安全部署至关重要,但前提是自我报告(SR)能够可靠地预测行为。近期研究记录了LLMs中自我报告与行为之间的显著脱节,但依赖于广泛的人格特质(大五人格),这些特质即使在人类中也只能弱预测特定行为。此外,孤立的对话会话结合弱上下文匹配使得尚不清楚LLMs是否真的缺乏连贯性,或是未满足检测这种连贯性所需的条件。我们将大五人格与计划行为理论(TPB)进行对比,后者测量针对特定行为的意图,并比广泛的人格特质更好地预测人类行为。我们在四个行为任务和11个前沿LLMs上进行实验,同时变化会话上下文和身份诱导。我们发现自我报告与行为之间的连贯性确实存在,但具有选择性。1)在共享对话中,计划行为理论达到了人类水平的连贯性;而大五人格则没有。2)在不同的对话中,连贯性仅在与即时提示无关的行为中存在,例如受训练影响的隐性偏见,而在行为受到上下文强烈提示时(如谄媚行为)则崩溃。3)角色提示使自我报告在不同对话中更一致,但并未使行为保持一致。这些发现表明,像大五人格这样粗略的人格框架可能不是测试部署行为的最佳工具。需要更具任务和行为特异性的工具,即便这些工具也必须在不同任务和上下文中进行评估。

Abstract
AI agents are increasingly being developed to accelerate scientific discovery, yet their practical capabilities in real research settings remain poorly understood. Existing benchmarks for AI agents rarely capture the complexity, heterogeneity, and extended reasoning required by scientific work, whereas benchmarks for scientific tasks often reduce research to static, direct problems and provide limited support for interactive evaluation. Here, we introduce SciAgentArena, a systematic benchmark for evaluating AI agents in real-world scientific research scenarios drawn from emerging needs across multiple domains. SciAgentArena comprises approximately 200 tasks with stepwise verification and an interactive, agent-agnostic environment for assessing diverse AI agents. Using this benchmark, we find that current agents can contribute effectively to well-specified data-analysis workflows, particularly when the task structure and evaluation criteria are clear. However, their performance remains uneven across scientific contexts: agents struggle to generate genuinely novel insights, sustain self-directed exploration, and formulate robust solutions for open-ended research questions. We further characterize common failure modes across agents and identify opportunities for improving their reliability, autonomy, and scientific reasoning. Together, SciAgentArena provides a practical framework for measuring progress in AI agents for science and for guiding the design of future agents capable of addressing complex scientific challenges.

Reducing the Complexity of Deep Learning Models for EEG Analysis on Wearable Devices

降低可穿戴设备上脑电图分析的深度学习模型复杂性
Roodi, Farough Shayeste, Moghaddam, Parham Zilouchian, Mohammadi-nasab, Mahdi, Modarressi, Mehdi, Nasab, Mostafa Ersali Salehi, Daneshtalab, Masoud
Abstract
Wearable healthcare devices are the fastest-growing Internet of Things (IoT) sector. Many automated healthcare services rely on two crucial biological signals, namely ECG and EEG, which reflect the activity of the heart and brain, respectively. Although deep neural networks are considered the primary way to process and analyze these signals, the very tight energy and computational power constraints in wearable devices are far below the computational, energy, and memory bandwidth demands of DNN models, thereby impeding the deployment of deep learning in many practical wearable services. This paper investigates the feasibility of deploying state-of-the-art DNN models in resource-constrained wearable devices. Notably, we explore the trade-off between accuracy and computational complexity of DNNs when parameter quantization and electrode reduction methods are used. Our investigation centers on several state-of-the-art DNN models designed for EEG signal analysis, specifically for detecting epileptic seizures. Our findings demonstrate that, when applied judiciously, these techniques can significantly reduce the complexity of the DNNs under consideration with minimal adverse effects on accuracy. These results reveal the explicit trade-offs between accuracy and complexity reduction encountered when adapting DNN-based online EEG analysis for wearable devices.

Prefill Awareness in Large Language Models

大型语言模型中的预填充意识
Wang, Andy, Mahajan, Parv, Africa, David Demitri, Souly, Alexandra, Taylor, Jordan, Kirk, Robert
Abstract
Safety-relevant studies of language models, including alignment and jailbreaking evaluations and AI control protocols, often rely on prefilling model outputs. If AI models can recognize and act on the fact their prior assistant messages have been inserted or edited, the effectiveness and validity of these methods could be compromised. We investigate whether frontier language models can distinguish between tampered and untampered assistant-side context, a capability we call prefill awareness. To do so, we construct a binary preference benchmark across three prefill mechanisms, filtering for cases where models show consistent stances. We find that frontier models show substantial prefill awareness: Claude Opus 4.5 detects prefills opposing its preferences in 9-35% of cases with a 0% false positive rate when prompted; additionally, models often revert towards baseline behavior without explicitly reporting that the prefill was foreign. Controlled ablations later also show that detection and resistance rely on different cues, where stylistic mismatch mainly affects whether models flag a prefill as foreign, while preference mismatch mainly affects whether they revert toward their baseline answer. We also examine more realistic agentic settings such as misalignment-continuation evaluations and SWE-bench trajectories, where frontier models sometimes disavow prefilled assistant turns in ways that depend strongly on dataset, task success, and hidden formatting artifacts. Our results indicate that prefill awareness is already a substantial confound for some prefill-based methods. We recommend that model developers track this capability in frontier systems.

Constructing Evaluation Datasets for Procedural Reasoning: Balancing Naturalness, Grounding, and Multi-Hop Coverage

构建程序推理评估数据集:平衡自然性、基础性和多跳覆盖率
Elshabrawy, Sarah, Dass, Rahul K., Goel, Ashok K.
Abstract
Evaluating procedural reasoning in AI-supported learning systems requires question-answer datasets that are both learner-like and grounded in the instructional knowledge the system is expected to use. We study how TMK-based question generation strategies affect dataset quality for procedural and multi-hop reasoning. We compare three strategies: strict generation from Task-Method-Knowledge (TMK) models, transcript-first generation with post-hoc TMK filtering, and TMK-aware generation that combines transcripts with structured guidance. To evaluate generated items, we introduce a grounding validation framework based on closed-set evidence units extracted from TMK models. The framework measures whether answers are supported by the underlying representation, whether questions are self-contained, and whether they target multi-hop procedural reasoning. Across 23 instructional topics and 690 generated question-answer pairs, strict TMK generation achieves the strongest overall quality, with 96.5% grounded questions and 92.6% usable questions. Transcript-first generation produces more learner-like questions but more context-dependent or weakly grounded items, while TMK-aware generation yields high raw multi-hop coverage but lower grounding. These results show that procedural richness and natural phrasing do not guarantee representational grounding, motivating explicit representation-aware validation for evaluation datasets in AI-supported learning.

A Tutorial on World Models and Physical AI

世界模型与物理人工智能教程
Oh, Il-Seok
Abstract
World modeling is emerging as a central principle for building intelligent systems capable of prediction, reasoning, and decision making. A central distinction can be drawn between explicit world models, which learn structured dynamics for rollout-based reasoning and planning, and implicit world models, which encode predictive structure within scalable learned representations. These complementary paradigms provide a foundation for physical AI in domains such as robotics and autonomous driving, enabling intelligence beyond reactive control under real-world constraints. Recent foundation models further suggest a pathway toward unified systems integrating perception, prediction, and action. Despite rapid progress, major challenges remain in hierarchical reasoning, long-horizon planning, and autonomous goal formation, which are critical for advancing toward artificial general intelligence. This tutorial presents a coherent framework in which diverse world modeling approaches are unified through shared predictive structure and differentiated by how such structure is represented and exploited.

The Containment Gap: How Deployed Agentic AI Frameworks Fail Public-Facing Safety Requirements

控制缺口:已部署的自主智能框架如何未能满足面向公众的安全要求
Hossain, Md Jafrin, Hossain, Mohammad Arif, Liu, Weiqi, Ansari, Nirwan
Abstract
Agentic large language model systems that autonomously invoke tools, maintain persistent memory, and execute multi-step plans are increasingly deployed in public-facing domains, including government services, healthcare triage, and financial advising. We ask whether the frameworks used to build these systems provide architectural-level structural safety guarantees. Applying six containment principles derived from a compositional model of agentic architectures, we audit three dominant frameworks (LangChain, AutoGPT, and OpenAI Agents SDK) and find no native compliance in any of them. Memory integrity, a defense against one of the most prevalent vulnerability classes, is not observed in any of the three evaluated frameworks. We validate these findings empirically: in a simulated government benefits agent built on LangChain, a single memory-poisoning write induces persistent targeted corruption across all tested seeds and backends, increasing the wrongful denial rate for targeted applicants to 88.9%. Under a complex five-factor policy, the same attack preserves aggregate accuracy while increasing targeted wrongful denials by 3.5x, rendering the corruption difficult to detect through standard monitoring. We then introduce two lightweight containment mechanisms: a memory integrity validator and a policy gate, which eliminate both attack vectors with sub-millisecond overhead (<0.2ms per call). We conclude that the current agentic framework ecosystem may not yet meet secure-by-default expectations for public-facing deployments and outline priority architectural interventions to enable trustworthy deployment in high-stakes, socially impactful applications.

MLUBench: A Benchmark for Lifelong Unlearning Evaluation in MLLMs

MLUBench:用于评估多模态大语言模型终身遗忘的基准
Li, He, Chi, Haoang, Wang, Qizhou, Mao, Yunxin, Zhang, Zhiheng, Tan, Jie, Liu, Tongliang, Yang, Wenjing, Han, Bo
Abstract
Multimodal large language models (MLLMs) are trained on massive multimodal data, making data unlearning increasingly important as data owners may request the removal of specific content. In practice, these requests often arrive sequentially over time, giving rise to the challenging problem of MLLM Lifelong Unlearning. However, most existing benchmarks are limited in scale and scope, failing to capture the complexities of MLLM lifelong unlearning. To fill this gap, we introduce the MLUBench, a large-scale and comprehensive benchmark featuring 127 entities across 9 classes under lifelong unlearning requests. We perform extensive experiments using MLUBench and reveal that existing unlearning methods suffer from severe, cumulative degradation. More critically, we further identify the unique challenge of this problem: unlike in unimodal models, MLLM lifelong unlearning is constrained by the need to preserve multimodal alignment. Continually unlearning from one modality could degrade the entire model. To alleviate this challenge, we propose LUMoE, an effective method. Experiments demonstrate that LUMoE significantly mitigates the degradation problem faced by baselines. The source code and the MLUBench dataset are open-sourced in https://github.com/lihe-maxsize/Lifelong_Unlearning_main.

Teach-and-Repeat: Accurately Extracting Operational Knowledge from Mobile Screen Demonstrations to Empower GUI Agents

教学与重复:从移动屏幕演示中准确提取操作知识以增强GUI代理
Zhang, Yudong, Hu, Lei, Liu, Daoyang, Liu, Jiawei, Luo, Yangfan, Liu, Xingyu, Wang, Zuojian, Gao, Zhilin
Abstract
Understanding the digital world on mobile devices is shifting from static UI perception to dynamic action comprehension. This capability enables models to convert visual state transitions into operational knowledge, defined as short natural-language sentences that describe action types, target UI elements, textual arguments, and execution orders. However, due to the highly diverse and heterogeneous UI designs across applications, existing vision-language models (VLMs) struggle to accurately infer these underlying operations. To bridge this gap, we introduce Teach VLM, a core model designed to translate mobile screen trajectories into step-wise operational knowledge by extracting and analyzing operation-related keyframes from demonstration videos. To address the scarcity of aligned training data, we develop a systematic data flywheel for scalable data acquisition. We further introduce a novel Chinese Mobile Screen Teach Benchmark for fine-grained evaluation. Building upon Teach VLM, we propose the Teach-and-Repeat paradigm, where the generated operational knowledge serves as an interpretable procedural reference to guide downstream screen-based execution agents. Extensive evaluations demonstrate that Teach VLM significantly outperforms strong VLM baselines, achieving state-of-the-art performance in operation semantics prediction. Furthermore, experiments in Android World show that our paradigm yields consistent Task Success Rate improvements for downstream agents. Together, Teach VLM and the Teach-and-Repeat paradigm offer a practical pathway from raw demonstrations to reusable task automation.

Diaz-Ireland, Gabriel, Prieto-Herráez, Diego, Peces, Mario García, Velázquez, Javier, Jain, Devika
Abstract
Environmental scientists spend disproportionate effort on data wrangling rather than analysis, and AI agents that automate geospatial workflows remain unvalidated: no benchmark evaluates agents operating through structured tool calling against real APIs. We introduce the GeoNatureAgent Benchmark, the first benchmark for environmental analysis agents that operate via structured tool calls to a production-style geospatial API. It comprises 93 tasks across 18 categories, covering municipality analysis, multi-turn conversation, spatial reasoning, cross-indicator synthesis, error handling and recovery, ranking, comparison, multilingual understanding, habitat analysis, and task rejection. Tasks are evaluated against an open, self-hostable API serving three environmental indicators across Spain and Portugal via sixteen tools. We evaluate seven LLMs (Claude Sonnet 4, DeepSeek V3.2, GLM-5, Gemini 2.5 Pro, Qwen3-235B, GPT-OSS-120B, Llama 4 Scout) under three temperature-1.0 seeds, reporting capability and per-case cost as orthogonal axes. We find: (1) Claude Sonnet 4 leads at 60.8% +/- 0.8%, followed by DeepSeek V3.2 at 56.3% +/- 3.1%, with no other model above 51%; (2) the cost-accuracy Pareto frontier is occupied mostly by open-weight models, with DeepSeek V3.2 offering 93% of Claude's capability at 11x lower cost ($0.011/case); (3) comparison tasks remain universally unsolved (0% on close-value comparisons), exposing systematic reasoning limits; and (4) structured tool calling against a real API is more discriminative than general-purpose GIS benchmarks, with accuracies 25-35 points lower. We further show extensibility by integrating BigEarthNet V2 land cover for Portugal alongside Spanish CO2 and erosion indicators. The benchmark, harness, and self-hostable API are publicly available.

Analyzing 80,814 accepted main-track papers from five premier AI conferences (ACL, CVPR, ICLR, ICML, NeurIPS) spanning 2017 to 2025, we show major AI topics advance through topical phase transitions: remaining marginal for years, then surging across venues within one to three years. Large language models became the dominant cross-venue topic by 2025, diffusion models rose with comparable abruptness, and language-model methods crossed into computer vision via vision-language models, whereas reinforcement learning compounded smoothly, distinguishing genuine phase transitions from ordinary growth. This structure is our primary contribution: a large-scale, cross-venue characterization of how AI research reorganizes. We then ask whether a transition leaves a detectable footprint before it peaks. We define an early-warning signature, four publication-dynamics criteria frozen on 2017-2021 data, and evaluate it out of sample on 2023-2025 transitions, obtaining a precision of 27% and recall of 63% against a 13.5% base rate. Applied to 2025 data, the signature flags reasoning and test-time compute, agentic AI, multimodal LLMs, retrieval-augmented generation, and world models as topics to monitor over 2026-2028.

人工智能研究主题是逐渐增长,还是通过突发的、可检测的跃迁推进?通过分析2017年至2025年间五个顶尖AI会议(ACL、CVPR、ICLR、ICML、NeurIPS)接受的80,814篇主轨道论文,我们展示了主要AI主题通过主题相变推进:在多年内保持边缘状态,然后在一到三年内在多个场合中激增。到2025年,大型语言模型成为跨场合的主导主题,扩散模型以相似的突发性上升,而语言模型方法通过视觉-语言模型跨入计算机视觉领域,强化学习则平稳增长,从而区分出真正的相变与普通增长。这一结构是我们的主要贡献:对AI研究如何重组的大规模、跨场合特征描述。接着,我们询问相变是否在达到峰值之前留下可检测的痕迹。我们定义了一个早期预警特征,基于2017-2021年的数据设定了四个出版动态标准,并在2023-2025年的相变中进行样本外评估,获得了27%的精确率和63%的召回率,基于13.5%的基线率。应用于2025年的数据,该特征标记了推理和测试时计算、代理AI、多模态LLMs、检索增强生成和世界模型等主题,作为2026-2028年需监测的主题。源代码也已在GitHub上公开,链接为 https://github.com/KurbanIntelligenceLab/ai-phase-transitions。

Fantastic Scientific Agents and How to Build Them: AgentBuild for Rietveld Refinement

奇妙的科学代理及其构建方法:用于Rietveld精修的AgentBuild
Shin, Woong, Bridges, Craig A., McDonnell, Marshall T., da Silva, Rafael Ferreira
Abstract
As scientific workflows shift from deterministic executables to LLM-based agents, the development practices on offer, such as fine-tuning, reinforcement learning, and prompt-and-go, bury the scientist's judgment. We propose treating agent construction as a workflow stage and introduce AgentBuild, which builds a scientific agent from a contract the scientist authors. The contract is a version-controlled rubric, a difficulty-graded curriculum, and a curated external knowledge base. A rubric-driven judge gates a meta-optimizer coding agent that edits the agent within a declared boundary, so the build compiles the agent, not the scientist's judgment. We instantiate this for Rietveld refinement of X-ray diffraction data through GSAS-II behind MCP and A2A, where a blank-harness construction run progresses through a lithium lanthanum zirconium oxide (LLZO) signal-to-noise ladder, reaches the 4 hour scan as a frontier case, and exposes the workflow-scope limits that remain. The same rubric that rewards credible fits also scores trajectory scope, making the frontier a contract failure rather than a pattern-fitting failure. As base models evolve, re-running AgentBuild is a re-tune, not a rebuild, and the scientist's authored contract remains the durable asset.

随着科学工作流程从确定性可执行文件转向基于大语言模型(LLM)的代理,现有的开发实践,如微调、强化学习和即问即答,抑制了科学家的判断。我们建议将代理构建视为工作流程的一个阶段,并引入AgentBuild,它根据科学家撰写的合同构建科学代理。该合同是一个版本控制的评分标准、一个难度分级的课程以及一个策划的外部知识库。由评分标准驱动的评判者控制一个元优化器编码代理,该代理在声明的边界内编辑代理,从而使构建过程编译的是代理,而不是科学家的判断。我们通过GSAS-II在MCP和A2A的支持下,为X射线衍射数据的Rietveld精修实例化这一过程,其中一个空白的构建运行通过锂镧锆氧化物(LLZO)信噪比阶梯进展,达到4小时扫描作为前沿案例,并揭示了仍然存在的工作流程范围限制。相同的评分标准不仅奖励可信的拟合,还对轨迹范围进行评分,使得前沿成为合同失败而非模式拟合失败。随着基础模型的发展,重新运行AgentBuild是一次重新调优,而不是重建,科学家撰写的合同仍然是持久的资产。

(Human) Attention Is (Still) All You Need: Human oversight makes AI-assisted social science reliable

(人类)注意力仍然是你所需要的一切:人类监督使得人工智能辅助的社会科学研究更为可靠
Zhu, Chen, Wang, Xiaolu, Zhang, Weilong
Abstract
Large language models (LLMs) are increasingly used for tasks once reserved for trained researchers, including hypothesis generation, specification choice, and drafting conclusions. We argue that the reliability of AI-assisted research depends not only on model capability, but also on how cognitive labour is structured between humans and machines. We study this problem through Human-in-the-Loop Economic Research (HLER), a decision architecture based on pre-commitment, decision sequencing, accountability, and attention allocation. In a pre-specified 2*4 factorial experiment with 280 complete research runs across four datasets, an unconstrained multi-agent baseline produced critical failures in 72% of runs. Using the same underlying model, the same agent decomposition, and identical prompts for the shared reasoning agents, HLER reduced the failure rate to 16% by imposing three architectural commitments: LLMs reason but do not execute data work, data and estimation are handled deterministically, and three human decision gates bind the workflow. Fisher's exact test rejects equality of failure rates at p<0.001. Reliability gains were largest on the least publicly represented dataset, a Qing-dynasty population register, consistent with a task-based production model with Frechet-distributed output quality. An 80-run ablation suggests that deterministic computation and human gates contribute independently, with exploratory evidence of complementarity. We interpret HLER as a research harness rather than an autonomous AI scientist: it sharply reduces failures, makes residual weaknesses more visible, and prevents unreliable claims from being advanced as publication-ready outputs.

大型语言模型(LLMs)越来越多地用于曾经只限于受过训练的研究人员的任务,包括假设生成、规范选择和撰写结论。我们认为,人工智能辅助研究的可靠性不仅依赖于模型的能力,还取决于人类与机器之间的认知劳动如何结构化。我们通过人机协作经济研究(Human-in-the-Loop Economic Research, HLER)来研究这个问题,这是一种基于预承诺、决策序列、问责制和注意力分配的决策架构。在一项预先指定的2*4因子实验中,针对四个数据集进行了280次完整的研究运行,结果显示,无约束的多智能体基线在72%的运行中出现了关键性失败。使用相同的基础模型、相同的智能体分解以及对共享推理智能体的相同提示,HLER通过施加三项架构承诺将失败率降低至16%:LLMs进行推理但不执行数据工作,数据和估计以确定性方式处理,以及三个由人类决策门控的工作流程。Fisher精确检验在p<0.001的水平上拒绝了失败率相等的假设。可靠性提升在公众代表性最少的数据集上最大,该数据集为清代人口登记册,这与基于任务的生产模型及Frechet分布的输出质量一致。一项80次运行的消融实验表明,确定性计算和人类门控独立贡献,并且有探索性证据表明它们之间存在互补性。我们将HLER解读为一种研究工具,而非自主的人工智能科学家:它显著减少了失败,使剩余的弱点更加明显,并防止不可靠的主张被作为可发表的成果提出。

WISE: A Long-Horizon Agent in Minecraft with Why-Which Reasoning

WISE:在Minecraft中具有为何-哪个推理的长时间跨度智能体
Cheng, Renmin, Chen, Changhao
Abstract
Rapid advances have been made in developing general-purpose embodied agent in environments like Minecraft through the adoption of LLM-augmented hierarchical approaches. Despite their promise, low-level controllers often become performance bottlenecks due to repeated execution failures. We argue that a key limitation is not only the lack of episodic memory, but also the decoupling of \textit{what-where-when} memory from \textit{which-why} reasoning. To address this, we propose \textbf{WISE} (Which-Why Informed Semantic Explorer), a long-horizon agent framework with an enhanced low-level controller equipped with a Causal Event Graph that augments episodic memory with explicit causal structure linking observations to task relevance. Unlike prior work such as MrSteve, which relies on feature similarity for retrieval, WISE enables robust recall under viewpoint changes and supports opportunistic task reordering through causal reasoning. Building on this memory, we propose an Opportunistic Task Scheduler that dynamically re-prioritizes subtasks when causally relevant opportunities are detected. We further equip WISE with a multi-scale progressive exploration strategy to provide spatially comprehensive observations for downstream reasoning. Experiments show that WISE largely improves task success and efficiency on long-horizon sparse tasks, particularly in settings requiring adaptive decision-making.

通过采用增强大型语言模型(LLM)的层次化方法,在Minecraft等环境中开发通用型具身智能体已取得快速进展。尽管这些方法前景广阔,但低级控制器往往因重复执行失败而成为性能瓶颈。我们认为,关键的限制不仅在于缺乏情节记忆,还在于 extit{什么-哪里-何时}记忆与 extit{哪个-为何}推理的解耦。为了解决这个问题,我们提出了 extbf{WISE}(Which-Why Informed Semantic Explorer),这是一个长时间跨度的智能体框架,配备了增强的低级控制器,使用因果事件图(Causal Event Graph)来增强情节记忆,并通过明确的因果结构将观察与任务相关性联系起来。与依赖特征相似性进行检索的先前工作(如MrSteve)不同,WISE能够在视角变化下实现稳健的回忆,并通过因果推理支持机会性任务重排序。在此记忆的基础上,我们提出了一种机会性任务调度器,当检测到因果相关的机会时,动态地重新优先考虑子任务。我们还为WISE配备了一种多尺度渐进探索策略,以提供空间上全面的观察,供下游推理使用。实验表明,WISE在长时间跨度的稀疏任务上显著提高了任务成功率和效率,尤其是在需要适应性决策的环境中。

DailyReport: An Open-ended Benchmark for Evaluating Search Agents on Daily Search Tasks

DailyReport:评估搜索代理在日常搜索任务中的开放式基准
Han, Jingxuan, Liu, Wei, Zhu, Mingyang, Wang, Youpeng, Wang, Ziwen, Qiu, Lin, Cao, Xuezhi, Cai, Xunliang, Fu, Zheren, Zhang, Licheng, Mao, Zhendong
Abstract
Search Agents (SAs) typically leverage large language models (LLMs) to support complex information-seeking tasks by autonomously exploring web sources and synthesizing information into comprehensive responses. For SAs evaluation, prior benchmarks mainly focus on specialized tasks that are unlikely to arise in real-world user scenarios. Moreover, their reliance on coarse task-level rubrics often limits evaluation interpretability. To bridge this gap, we introduce DailyReport, an open-ended benchmark to evaluate SA capabilities on daily search tasks. It contains 150 open-ended tasks with 3,546 associated rubrics, capturing widely discussed and timely information demands of real-world users. Each task is decomposed into subtasks and evaluated with cascade rubrics across disentangled dimensions. Through cascade performance attribution and user-centric aggregation, we derive highly interpretable scores for each dimension, along with a user preference score. Our results on 17 agentic systems show that current systems still fall short of users' expectations. To facilitate future research, our dataset and code are made publicly available at https://github.com/AGI-Eval-Official/DailyReport.

HarnessBridge: Learnable Bidirectional Controller for LLM Agent Harness

HarnessBridge:可学习的双向控制器用于大型语言模型代理的控制
Wang, Xiaoxuan, Wang, Haixin, Taylor, Alexander, Cong, Jason, Sun, Yizhou, Wang, Wei
Abstract
Large language models are increasingly deployed as agents for long-horizon tasks, yet their performance is shaped not only by model capability and environment design, but also by the harness that mediates agent--environment interaction. Existing harnesses are largely manually engineered, making them difficult to scale as trajectories grow longer and interactions become more complex. In this work, we ask whether harness can be generated by a learnable plug-in module that can be trained in an end-to-end fashion. We introduce HarnessBridge, a lightweight learnable harness controller that parameterizes the agent--environment interface as a bidirectional projection. HarnessBridge learns two bidirectional projections: observation projection, which distills raw trajectories into compact, decision-relevant states, and action projection, which converts proposed actions into executable transitions or trajectory-grounded rejections. We train HarnessBridge on a harness supervision dataset via unified instruction tuning. On Terminal-Bench~2.0 and SWE-bench Verified, HarnessBridge matches or surpasses strong specialized harnesses while substantially reducing token usage and trajectory length, and generalizes from smaller generators to larger commercial models.

大型语言模型越来越多地被用作长时间任务的代理,但它们的性能不仅受到模型能力和环境设计的影响,还受到调节代理与环境交互的控制器的影响。现有的控制器主要是手动设计的,这使得它们在轨迹变长和交互变得更加复杂时难以扩展。在本研究中,我们探讨是否可以通过一个可学习的插件模块生成控制器,该模块可以以端到端的方式进行训练。我们介绍了HarnessBridge,一个轻量级的可学习控制器,它将代理与环境的接口参数化为双向投影。HarnessBridge学习两个双向投影:观察投影,它将原始轨迹提炼为紧凑的、与决策相关的状态;以及动作投影,它将提议的动作转换为可执行的转变或基于轨迹的拒绝。我们通过统一的指令调优在控制器监督数据集上训练HarnessBridge。在Terminal-Bench~2.0和SWE-bench Verified上,HarnessBridge的表现与强大的专业控制器相匹配或超越,同时显著减少了令牌使用和轨迹长度,并且能够从较小的生成器推广到更大的商业模型。

The Hidden Power of Scaling Factor in LoRA Optimization

LoRA优化中缩放因子的隐秘力量
Zhang, Zicheng, Li, Haoran, Wang, Jiaxing, Gong, Guoqiang, Li, Anqi, Hu, Yudong, Xiong, Ting, Gao, Yurong, Hu, Junxing, Jiang, Zhida, Zhang, Yifeng, Liu, Pengzhang, Jiang, Qixia
Abstract
In Low-Rank Adaptation (LoRA), the scaling factor $\alpha$ is often treated as a mere complement to the learning rate, yet its role in optimization remains poorly understood. In this paper, we reveal that the scaling factor $\alpha$ and the learning rate function differently, with $\alpha$ emerging as the dominant driver of effective optimization, delivering gains that cannot be replicated by learning rate scaling alone. Through the synergy of extensive empirical analysis and a theoretical Signal-Drift framework, we uncover three findings into LoRA's scaling mechanism: First, LoRA's spectral suppression smooths the optimization landscape, rendering standard hyperparameters overly conservative and creating an optimization gap. Second, when leveraging this smoothness to accelerate convergence, $\alpha$ outperforms the learning rate by amplifying the task signal without increasing the drift ratio. Third, the optimal scaling factor follows a sublinear relationship with the rank, well characterized by a square-root law with an unexpectedly large coefficient, revealing the insufficient scaling of existing rank-tied heuristics. Based on these insights, we propose LoRA-$\alpha$, a minimalist framework that restores $\alpha$ to its principled regime, making LoRA compatible with standard small learning rates. Extensive evaluations across diverse tasks demonstrate that LoRA-$\alpha$ consistently improves performance while streamlining hyperparameter search, unleashing the learning potential of LoRA.

在低秩适应(Low-Rank Adaptation, LoRA)中,缩放因子 $eta$ 通常被视为学习率的补充,但其在优化中的作用仍然不够明确。本文揭示了缩放因子 $eta$ 与学习率在功能上的不同,$eta$ 成为有效优化的主要驱动因素,其带来的收益无法仅通过学习率缩放来复制。通过广泛的实证分析与理论信号漂移(Signal-Drift)框架的协同,我们揭示了LoRA缩放机制的三个发现:首先,LoRA的谱抑制平滑了优化景观,使得标准超参数过于保守,从而产生了优化差距。其次,在利用这种平滑性加速收敛时,$eta$ 通过增强任务信号而不增加漂移比率,超越了学习率的表现。第三,最优缩放因子与秩之间呈亚线性关系,符合平方根法则,并具有意外的大系数,揭示了现有秩绑定启发式方法的缩放不足。基于这些见解,我们提出了LoRA-$eta$,一个简约框架,将$eta$ 恢复到其原则性范围,使LoRA与标准的小学习率兼容。在多样任务上的广泛评估表明,LoRA-$eta$ 一直在提升性能的同时简化超参数搜索,释放了LoRA的学习潜力。

Zero-source LLM Hallucination Detection with Human-like Criteria Probing

基于人类标准探测的零源大型语言模型幻觉检测
Yang, Jiahao, Zhang, Shuhai, Kang, Hailong, Liu, Feng, Chen, Qi, Tan, Mingkui
Abstract
Large language models (LLMs) often hallucinate by generating factually incorrect or unfaithful content, posing significant risks to their safe use. Detecting such hallucinations is particularly challenging under the zero-source constraint, where no model internals or external references are available, and detection must rely solely on the textual query-answer pair. In this paper, we propose Human-like Criteria Probing for Hallucination Detection (HCPD), a paradigm that emulates the multi-faceted reasoning of human evaluators. Its core is a Human-like Criteria Probing (HCP) mechanism, in which a LLM agent adaptively decomposes its judgment into a weighted set of interpretable criteria and aggregates criterion-specific scores into a final truthfulness measure. To achieve this adaptive capability, we introduce a reward-based alignment scheme using only weak supervision from semantic consistency. At inference, we employ a multi-sampling aggregation strategy to ensure robust decisions while preserving full interpretability. We further provide theoretical analysis supporting the reliability of our approach. Extensive experiments show that HCPD consistently outperforms state-of-the-art baselines, offering an effective and explainable solution for zero-source hallucination detection. Code is available at https://github.com/TRISKEL10N/HCPD.

大型语言模型(LLMs)常常通过生成事实不准确或不忠实的内容而产生幻觉,这对其安全使用构成了重大风险。在零源约束下,检测此类幻觉尤其具有挑战性,因为没有模型内部信息或外部参考,检测必须仅依赖于文本查询-回答对。本文提出了一种用于幻觉检测的人类标准探测(HCPD)范式,模拟人类评估者的多维推理。其核心是人类标准探测(HCP)机制,其中LLM代理自适应地将其判断分解为一组加权的可解释标准,并将标准特定的分数汇总为最终的真实性度量。为了实现这一自适应能力,我们引入了一种基于奖励的对齐方案,仅使用来自语义一致性的弱监督。在推理时,我们采用多采样聚合策略,以确保决策的稳健性,同时保持完全的可解释性。我们进一步提供了理论分析以支持我们方法的可靠性。大量实验表明,HCPD在零源幻觉检测中始终优于最先进的基线,提供了一种有效且可解释的解决方案。代码可在 https://github.com/TRISKEL10N/HCPD 获取。

MDForge: Agentic Molecular Dynamics Pipeline Design under Sparse Simulator Feedback

Wang, Zehong, Ma, Yijun, Schmidt, Connor R., Ma, Tianyi, Sun, Weixiang, Li, Ziming, Guo, Xiaoguang, Zhang, Chuxu, Webber, Matthew J., Ye, Yanfang
Abstract
Molecular dynamics (MD) is the canonical in-silico method for atomistic molecular science, simulating molecular behavior from first-principle physics. Designing an MD pipeline for a new system requires substantial expert knowledge: running it on even one molecule is expensive, ruling out trial-and-error. We automate this expert pipeline-design process with an LLM agent. Unlike existing MD agents that orchestrate a predefined tool set, we treat pipeline design as open-ended code generation in which the agent's behavior is reshaped online by verbal reward. Specifically, we build MDForge, an LLM agent whose in-context update rule densifies the sparse reward via a multi-agent debate among physics experts. On three SAMPL host-guest binding free-energy benchmarks, MDForge automatically designs MD pipelines competitive with human experts. Deployed on a library of unseen candidate guests, its CB[7] pipeline discovers a novel binder that wet-lab competition NMR confirms is a high-affinity, picomolar CB[7] binder. Our data and code are available at https://github.com/Zehong-Wang/MDForge.

Iterating Toward Better Search: A Two-Agent Simulation Framework for Evaluating Agentic Search Architectures in E-Commerce

Abstract
We present a modular two-agent simulation framework for evaluating conversational shopping assistant architectures. An independent buyer agent, configured with personas, missions, and patience levels, is paired with an interchangeable responder that integrates with a real e-commerce search API. Holding the buyer constant across experiments enables controlled comparison of responder designs on identical scenarios. Using 2011 conversations across 14 persona buckets, we establish four empirical findings. First, rolling-window memory outperforms intent-extraction memory on all quality metrics while being 35% faster per query. Second, illustrating rapid evidence-driven iteration, a systematic failure analysis of a responder version enables targeted fixes that reduce failure and near-failure rates by 62% across the full dataset. Third, swapping the responder LLM backbone from Gemini~2.5 to Llama~3.3~70B costs 0.16--0.45 points despite identical architecture. Finally, we document systematic philosophical disagreement between frontier LLM judges: Gemini rewards process correctness while Claude demands concrete outcomes, despite using the same evaluation prompt.

MARS: Margin-Adversarial Risk-controlled Stopping for Parallel LLM Test-time Scaling

MARS:用于并行大语言模型测试时缩放的边际对抗风险控制停止
Chen, Wenbo, Li, Puheng, Liu, Mengyang, Su, Weijie, Xie, Tianpei
Abstract
Parallel test-time scaling samples many reasoning traces and majority-votes their answers, improving LLM accuracy but requiring traces to run to completion, incurring substantial computational overhead. We observe that probing partial traces at intermediate checkpoints can extract current answers without disrupting generation, revealing an evolving aggregate vote. Based on this observation, we introduce MARS, a margin-adversarial stopping rule that estimates which active traces are likely to change their answers and stops once the leader remains safe under a conservative bound on future vote movement. The rule separates two sources of uncertainty. It learns the trace-level switch probabilities that determine how much of the current margin is likely to be retained, while handling the harder question of where switching traces land through an adversarial bound calibrated from warmup traces. With true switch probabilities, MARS guarantees with high probability that the early-stopped answer matches the full-budget vote. In practice, a five-feature logistic model closely matches oracle switching behavior. Across three reasoning models and three competition-math benchmarks, MARS saves 25-47% of self-consistency tokens and 14-29% on top of DeepConf Online, a strong confidence-weighted baseline that already filters and truncates weak traces, while matching the accuracy of the corresponding full-budget baselines.

PRISMR: Overcoming Parse Collapse in Multimodal Listwise Ranking via Parameterized Representation Internalization

PRISMR:通过参数化表示内化克服多模态列表排名中的解析崩溃
Jiang, Hao, Li, Xin, Wang, Annan, Yang, Zhi, Zhang, Haoxiang, Zhang, Yichi, Lin, Weisi
Abstract
Generative listwise ranking with Large Multimodal Models (LMMs) aims to capture global list context in a single forward pass, but its effectiveness degrades in long-context multimodal scenarios. We identify a recurring failure mode, parse collapse, where the autoregressive decoder produces fluent yet incomplete rankings by silently omitting candidates and terminating early. This failure stems from limited context utilization rather than simple formatting mistakes, making prompt engineering and constrained decoding insufficient. We propose PRISMR (Parameterized Representation Internalization for Semantic Multimodal Ranking), a framework that replaces transient in-context list processing with parametric structural conditioning. PRISMR uses a lightweight hypernetwork to encode multimodal candidates in parallel and generate item-specific LoRA weights, which are synthesized into an instance-specific adapter for a LMM. This paradigm enables more robust internalization of list structure while preserving the base model. We further introduce a large-scale multimodal review-ranking benchmark for evaluation. Experiments demonstrate that PRISMR substantially reduces parse collapse, improves listwise ranking performance, and transfers effectively across domains and instruction-tuned backbones.

Learning What to Remember: A Cognitively Grounded Multi-Factor Value Model for Agentic Memory

学习记忆内容:一种基于认知的多因素价值模型用于代理记忆
Chen, Zhibao, Cheng, Qian
Abstract
Long-running LLM agents accumulate interaction histories far larger than any context window, forcing a standing decision: what to encode deeply, what to forget, and what to retrieve under a fixed memory budget. Production systems answer with semantic similarity or recency -- both mis-specified for the forgetting decision, which is made at consolidation time before the future query is known. We propose a multi-factor memory value function V(m)=\sum_i w_i f_i(m) over seven interpretable factors (emotional intensity, goal relevance, value alignment, self/user relevance, task utility, reliability, and usage history) drawn from cognitive psychology, whose weights are learned from a downstream objective by a gradient-free optimiser, and whose single scalar uniformly controls encoding depth, forget risk, and retrieval rank. We make a methodological point: on LongMemEval, scoring goal relevance against the held-out evaluation question saturates gold-evidence retention at \approx 0.98 -- this measures retrieval, not forgetting. In the realistic blind regime, a learned multi-factor value retains 0.770 \pm 0.011 of gold evidence across 479 usable cases, versus 0.657 for uniform weights, 0.518 for the best single factor, and 0.368 for recency; every paired gap's 95% bootstrap CI is above zero, and a neural network over the same factors ties the linear model. The learned weights are interpretable -- reliability, emotional intensity, and self/user relevance dominate, while query-time goal similarity is correctly down-weighted for the forgetting decision. A controlled synthetic task with planted confounds confirms the learner recovers a separating weighting (1.00 retention) where uniform weighting fails (0.62).

长期运行的LLM代理积累的交互历史远大于任何上下文窗口,这迫使我们做出一个持续的决策:深度编码什么,遗忘什么,以及在固定的记忆预算下检索什么。生产系统通过语义相似性或近期性来回答——这两者对于遗忘决策的指定都是错误的,因为该决策是在巩固时做出的,而未来的查询尚未确定。我们提出了一个多因素记忆价值函数V(m)=∑_i w_i f_i(m),该函数基于来自认知心理学的七个可解释因素(情感强度、目标相关性、价值一致性、自我/用户相关性、任务效用、可靠性和使用历史),其权重由无梯度优化器从下游目标中学习,并且该单一标量均匀控制编码深度、遗忘风险和检索排名。我们提出一个方法论观点:在LongMemEval上,针对保留的评估问题评估目标相关性会使黄金证据的保留饱和至约0.98——这测量的是检索,而非遗忘。在现实的盲态下,学习的多因素价值在479个可用案例中保留了0.770 ± 0.011的黄金证据,而均匀权重为0.657,最佳单因素为0.518,近期性为0.368;每个配对差距的95%自助置信区间均高于零,而在相同因素上的神经网络与线性模型相当。学习到的权重是可解释的——可靠性、情感强度和自我/用户相关性占主导地位,而查询时的目标相似性在遗忘决策中被正确地降低权重。一个带有植入混淆的受控合成任务确认学习者在均匀加权失败(0.62)时恢复了分离加权(1.00保留)。该基础设施是开源的;所有实验均在单个CPU上运行,无需API调用。

Abstract
We present OpenMedQ, a medical vision-language model pretrained on the broadest fully-open medical mix to date: 14 datasets totaling ~3.35M pretraining samples spanning pathology, radiology, microscopy, and text-only clinical QA. OpenMedQ reaches state-of-the-art BLEU-1 on PathVQA (75.9), beating Med-PaLM M variants up to 562B parameters (~80x larger), and matches the best reported VQA-MED BLEU-1 (64.5). Its vision encoder, transferred to 8 unseen medical classification benchmarks under an identical downstream recipe, obtains the highest average macro-F1 (0.757) among BiomedCLIP (0.745), PMC-CLIP (0.745), PubMedCLIP (0.746), and a from-scratch baseline (0.616).

Multi-Modal Agents for Power Distribution Defect Detection: An Evaluation of Foundation Models

用于电力分配缺陷检测的多模态智能体:基础模型的评估
Quan, Quan
Abstract
The power distribution network is critical to reliable electricity delivery, yet traditional inspection methods face limitations in semantic understanding, generalization, and closed-loop automation. To address these challenges, this paper proposes a Multi-Modal Agent framework specifically for power distribution defect detection. Central to this study is the systematic evaluation of multimodal foundation models as unified cognitive engines. We rigorously assess their integrated performance across three critical capabilities: (1) Perception, where the model must accurately identify equipment and generate expert-level descriptions of defects; (2) Reasoning, where the model interprets visual findings to diagnose causes, assess severity, and plan maintenance strategies based on domain knowledge; and (3) Tool Usage, where the model acts as an autonomous operator to execute actions -- such as querying knowledge bases or generating work orders -- to achieve closed-loop maintenance. To support this evaluation, a domain-specific evaluation dataset and a comprehensive benchmark are developed. Experimental results demonstrate the strengths and limitations of current foundation models in these three dimensions, providing empirical evidence for deploying autonomous agents in high-stakes industrial environments.

A Mathematical Forum Platform for Collaborative Problem Solving and Dataset Generation for AI Reasoning

一个用于协作问题解决和AI推理数据集生成的数学论坛平台
Erkinov, Akbar, Abdurasulov, Nurmukhammad
Abstract
Sharing mathematical content in online forums remains a significant friction point for students and educators: writing raw LATEX is error-prone, standalone optical character recognition tools require platform switching, and current forum software offers no integrated path from a photograph of a formula to a rendered post. We present a unified system that eliminates this friction by embedding an image to LATEX conversion pipeline directly inside a forum posting interface. A user uploads or captures an image of a mathematical expression; the system routes it through the Mathpix OCR API, detects whether the returned output is LATEX or plain text containing inline math, applies the appropriate delimiter normalisation, and renders a live preview in either LATEX or Markdown mode before the post is committed to the database. The architecture is organized in three loosely coupled layers: image processing, rendering, and storage, and supports both desktop and mobile clients. A provisional US patent application has been filed covering the core methods. We describe the full system design, each component in detail, the data schema, and the key technical innovations, and we position the work against existing standalone tools and forum platforms to demonstrate the practical gap it closes. Beyond immediate usability, we argue that a deployed platform of this kind constitutes a continuously growing, community-validated dataset of mathematical problems and step-by-step solutions, a resource that can be used to train and benchmark AI systems for accurate mathematical reasoning

Structured Testbench Generation for LLM-Driven HDL Design and Verification-Oriented Data Curation

面向LLM驱动的HDL设计与验证的数据整理的结构化测试平台生成

Abstract
Automated testbench generation has become a critical bottleneck in large language model (LLM)-driven Register Transfer Level (RTL) workflows, where large numbers of candidate designs must be verified rapidly and reliably. Existing prompt-based approaches treat testbench generation as unconstrained code synthesis, yielding stochastic outputs with high token cost, low reproducibility, and insufficient coverage. To address this gap, we present STG, a Structured Testbench Generation framework that exploits the inherent structure of hardware designs to generate deterministic testbenches. As a direct verification tool, STG runs 720x faster than an iterative LLM-based testbench generation flow and higher rate of successful compilation, achieves higher coverage, and reduces false-pass verdicts on incorrect DUTs. STG also helps identify errors in RTL generation benchmarks by exposing faulty benchmark testbenches. As a data curation engine, it is 11x faster than LLM-based filtering on a single CPU core with 127x less energy, and the resulting distilled models provide state-of-the-art performance in our multi-benchmark evaluation. As a test-time scaling oracle, it reduces node count by 14-47\%. Our models are available at https://huggingface.co/collections/AS-SiliconMind/siliconmind-v12.

APCyc: Property-Informed Design of Cyclic Peptides via Automated Cyclization

APCyc:通过自动环化实现基于属性的信息化环肽设计
Zhao, Yifan, Qin, Lang, Chen, Jintai
Abstract
Cyclic peptides represent a promising class of therapeutic compounds in modern drug discovery, often offering improved stability and binding affinity. However, the de novo design of cyclic peptides remains challenging because methods must identify pocket-adaptive cyclization patterns and linkage sites while simultaneously controlling drug-relevant properties. This challenge is particularly pronounced for recent generative models trained predominantly on linear peptide data, which may fail to capture cyclization-specific constraints. To address the limitation, we introduce APCyc, a target-aware de novo cyclic peptide generation framework that explicitly models cyclization and jointly optimizes multiple essential physicochemical properties. By using an expanded residue vocabulary and explicitly encoding cyclization-site and linkage-type information, APCyc learns cyclization-aware representations and leverages Bayesian posterior guidance to steer sampling toward cyclic peptides satisfying multiple property objectives. Experimental results demonstrate that our model learns target-dependent cyclization preferences, and enables effective and controllable multi-property optimization for cyclic peptide design.

环肽在现代药物发现中代表了一类有前景的治疗化合物,通常提供更好的稳定性和结合亲和力。然而,环肽的从头设计仍然具有挑战性,因为方法必须识别适应口袋的环化模式和连接位点,同时控制与药物相关的属性。这个挑战在最近主要基于线性肽数据训练的生成模型中尤为明显,因为这些模型可能无法捕捉特定于环化的约束。为了解决这一限制,我们提出了APCyc,一个目标感知的从头环肽生成框架,明确建模环化并联合优化多个基本的物理化学属性。通过使用扩展的残基词汇,并明确编码环化位点和连接类型信息,APCyc学习环化感知的表示,并利用贝叶斯后验引导将采样引导向满足多个属性目标的环肽。实验结果表明,我们的模型学习了目标依赖的环化偏好,并实现了环肽设计的有效且可控的多属性优化。本文的源代码可在 https://github.com/HKUSTGZ-ML4Health-Lab/APCyc 获取。

The Illusion of Multi-Agent Advantage

多智能体优势的幻觉
Jwalapuram, Prathyusha, Lin, Hehai, Li, Chuyuan, Jiao, Fangkai, Wang, Sudong, Ming, Yifei, Ke, Zixuan, Qin, Chengwei, Carenini, Giuseppe, Joty, Shafiq
Abstract
Prevailing wisdom posits that Multi-Agent Systems (MAS) are superior to Single-Agent Systems (SAS), citing advantages like context protection, parallel processing and distributed decision-making. However, empirical support for this claim relies primarily on comparisons with SAS baselines using benchmarks that prioritize isolated reasoning tasks, which do not adequately assess these advantages. Focusing on automatically generated MAS that are designed for enhanced generalizability over manually-designed counterparts, we perform a rigorous, systematic evaluation against SAS, specifically Chain-of-Thought with Self-Consistency (CoT-SC). Across traditional reasoning datasets and tasks with interactive multi-step workflows (e.g., BrowseComp-Plus), we demonstrate that automatic MAS consistently underperform CoT-SC despite being up to 10x more expensive. To isolate these failures from limitations inherent to task structure, we introduce a diagnostic synthetic dataset tailored for MAS featuring explicit task decomposition, context separation and parallelization potential. We show that expert-architected MAS consistently outperforms automatically generated architectures in both raw performance and cost-efficiency on this dataset, demonstrating that existing evaluation frameworks mask critical architectural gaps and inefficiencies of complex MAS by failing to account for the marginal utility of increased computational cost. Critically, systematic deconstruction of the generated MAS architectures reveals that current automated design paradigms produce architectural bloat that prioritizes superficial complexity which does not translate into functional utility, exposing a fundamental misalignment with multi-agent principles.

现有的观点认为,多智能体系统(MAS)优于单智能体系统(SAS),其优势包括上下文保护、并行处理和分布式决策。然而,这一说法的实证支持主要依赖于与SAS基准的比较,这些基准优先考虑孤立推理任务,未能充分评估这些优势。我们专注于自动生成的MAS,这些系统旨在增强可泛化性,相较于手动设计的系统,我们对SAS进行了严格的系统评估,特别是链式思维与自我一致性(CoT-SC)。在传统推理数据集和具有交互式多步骤工作流程的任务(例如,BrowseComp-Plus)中,我们证明自动生成的MAS在性能上始终低于CoT-SC,尽管其成本高达10倍。为了将这些失败与任务结构固有的限制隔离开来,我们引入了一个针对MAS的诊断合成数据集,该数据集具有明确的任务分解、上下文分离和并行化潜力。我们展示了专家设计的MAS在该数据集上在原始性能和成本效率上始终优于自动生成的架构,表明现有的评估框架掩盖了复杂MAS的关键架构缺陷和低效性,因为它未能考虑到增加计算成本的边际效用。关键的是,对生成的MAS架构进行系统性解构揭示了当前的自动设计范式产生了架构膨胀,优先考虑表面复杂性而未能转化为功能效用,暴露了与多智能体原则之间的根本不一致。

Otters++: A Time-to-first-spike Based Energy Efficient Optical Spiking Transformer

Otters++:基于首次脉冲时间的能效光脉冲变换器
Yan, Zhanglu, Mao, Jiayi, Tang, Kaiwen, Li, Fanfan, Pan, Gang, Luo, Tao, Zhu, Bowen, Liu, Qianhui, Wong, Weng-Fai
Abstract
Spiking neural networks (SNNs) are promising for energy-efficient inference, and time-to-first-spike (TTFS) coding is especially attractive because each neuron fires at most once. In practice, however, this benefit is often reduced by the cost of computing a temporal decay term and multiplying it by the synaptic weight. We address this issue by turning a physical hardware "bug," the natural signal decay in optoelectronic devices, into the main computation of TTFS, named Otters++. Specifically, we use the measured decay of a custom In$_2$O$_3$ optoelectronic synapse to directly realize the TTFS temporal term, removing the need for explicit digital decay computation. To scale this idea to Transformer models, we establish a layer-wise functional equivalence between the Otters++ and a quantized neural network (QNN), and develop a hybrid training method that uses device-faithful SNN computation in the forward pass and QNN straight-through gradients through the equivalent QNN path in the backward pass, together with model distillation. This avoids differentiation through discrete first-spike events and reduces the over-sparsity problem in direct TTFS-SNN training. We further make training aware of measured device noise by sampling run-to-run variation, and refine the system-level energy model by accounting for device sharing and multi-hop communication. On GLUE dataset, Otters++ improves the average score to 84.17\% while maintaining a clear energy advantage over prior spiking Transformer baselines. These results show that physically grounded TTFS computing can be efficient, trainable, and robust under realistic hardware effects.

脉冲神经网络(SNNs)在能效推理方面展现出良好的前景,而首次脉冲时间(TTFS)编码尤其具有吸引力,因为每个神经元最多只发射一次。然而,在实际应用中,这一优势常常因计算时间衰减项及其与突触权重相乘的成本而降低。我们通过将物理硬件的“缺陷”——光电设备中的自然信号衰减——转变为TTFS的主要计算,提出了解决方案,命名为Otters++。具体而言,我们利用定制的In$_2$O$_3$光电突触的测量衰减直接实现TTFS时间项,从而消除了显式数字衰减计算的需求。为了将这一思路扩展到变换器模型,我们建立了Otters++与量化神经网络(QNN)之间的逐层功能等价关系,并开发了一种混合训练方法,该方法在前向传播中使用设备忠实的SNN计算,在后向传播中通过等效QNN路径使用QNN直通梯度,并结合模型蒸馏。这避免了对离散首次脉冲事件的微分,并减少了直接TTFS-SNN训练中的过度稀疏问题。我们进一步通过采样运行间变异来使训练考虑测量的设备噪声,并通过考虑设备共享和多跳通信来完善系统级能量模型。在GLUE数据集上,Otters++将平均得分提高至84.17\%,同时在能量上明显优于之前的脉冲变换器基线。这些结果表明,基于物理的TTFS计算在现实硬件影响下可以高效、可训练且具有鲁棒性。

SciR: A Controllable Benchmark for Scientific Reasoning in LLMs

SciR:一个可控的科学推理基准用于大型语言模型
Beckmann, Pierre, Valentino, Marco, Freitas, Andre
Abstract
Three paradigmatic forms of inference recur across scientific reasoning: deduction, induction, and causal abduction. Reliably evaluating LLMs on these in scientific settings is currently out of reach: scientific benchmarks built on human annotations are costly and lack mechanistic ground truth, while synthetic logical-reasoning benchmarks do not resemble real scientific documents. We introduce SciR, a benchmark that combines multi-paradigm reasoning with controllable scientific rendering, anchored on three paradigmatic scientific problems. Tasks are generated from formal objects (deduction tree, inductive rule hypothesis, causal graph) to guarantee verifiable answers, then rendered into multi-document scientific discourse via per-track domain-tuned genres. The construction lets us independently vary two difficulty axes: how hard it is to extract the key information needed for inference, and how hard the principled inference itself is. We test six models. Both axes hurt every model, and their effects compound. The rendering even hurts neurosymbolic pipelines, which hand inference to a verified solver. The two axes yield a per-model extraction-vs-inference profile: for instance, reasoning models like deepseek-r1 mostly surpass non-reasoning instruct models on the inference axis. To our knowledge, SciR is the first multi-paradigm scientific-reasoning benchmark with parametric control on both extraction and inference difficulty.

Nous: An Attempt to Extract and Inject the Cognition Behind Prediction-Market Behavior

Nous:尝试提取和注入预测市场行为背后的认知
Qian, Haowei
Abstract
As LLM agents proliferate in prediction markets and collective decision-making, they risk a cognitive monoculture: agents built on shared foundation models produce correlated forecasts, and recent measurement finds frontier-model errors correlated at r ~ 0.77. We ask whether human cognitive diversity can be recovered from behavior and transferred to LLM agents. Nous extracts a structured eight-dimension behavioral profile from real Polymarket trading activity and injects it into agents through prompts. Our central finding is a dissociation between the two halves of that pipeline. Extraction works, partially: across 100 wallets, 8 of 14 parameters are temporally stable (split-half ICC >= 0.5, bootstrap CI lower bound > 0.3; contrarian score reaches ICC ~ 0.9); wallets are identifiable from their profiles well above chance (top-1 retrieval 17-22% vs. 1% chance); and two of four pre-specified dimensions rank-correlate with future realized profit out-of-sample, though the correlations do not survive behavioral-confound controls. Prompt-level injection does not measurably transmit it: on a semantic embedding metric, structured injection shows no significant advantage over a length-matched control on any model, and the diversity it induces neither reduces ensemble error correlation nor improves Brier score -- a null that persists across exploratory checks on sampling temperature, profile diversity, and question difficulty. Measuring the prompts themselves locates the compression before the model: the structure-to-narrative translator emits near-uniform prompts whose spread does not track profile spread. We position Nous as measuring the cognitive-monoculture problem and the limits of a prompt-level remedy, motivating deeper, below-the-prompt injection (fine-tuning, activation steering).

Augmentation techniques for video surveillance in the visible and thermal spectral range

可见光与热红外光谱范围内的视频监控增强技术
Buhrmester, Vanessa, Grosselfinger, Ann-Kristin, Munch, David, Arens, Michael
Abstract
In intelligent video surveillance, cameras record image sequences during day and night. Commonly, this demands different sensors. To achieve a better performance it is not unusual to combine them. We focus on the case that a long-wave infrared camera records continuously and in addition to this, another camera records in the visible spectral range during daytime and an intelligent algorithm supervises the picked up imagery. More accurate, our task is multispectral CNN-based object detection. At first glance, images originating from the visible spectral range differ between thermal infrared ones in the presence of color and distinct texture information on the one hand and in not containing information about thermal radiation that emits from objects on the other hand. Although color can provide valuable information for classification tasks, effects such as varying illumination and specialties of different sensors still represent significant problems. Anyway, obtaining sufficient and practical thermal infrared datasets for training a deep neural network poses still a challenge. That is the reason why training with the help of data from the visible spectral range could be advantageous, particularly if the data, which has to be evaluated contains both visible and infrared data. However, there is no clear evidence of how strongly variations in thermal radiation, shape, or color information influence classification accuracy. To gain deeper insight into how Convolutional Neural Networks make decisions and what they learn from different sensor input data, we investigate the suitability and robustness of different augmentation techniques...

AAbAAC: An Annotated Corpus for Autoimmunity Information Extraction

AAbAAC:用于自身免疫信息提取的注释语料库
Maury, Fabien, Grosdidier, Solène, de Dieuleveult, Maud, Coulet, Adrien
Abstract
Despite advances in information extraction driven by deep learning and large language models, performance gaps remain in highly specialized biomedical fields, where domainspecific complexity poses challenges for generalist models. In this work, we focus on the domain of autoimmunity, where the main entities of interest are autoimmune diseases, autoantibodies (i.e., molecules that may mark or cause these diseases), their molecular targets, their location in the body, and their associated clinical signs. Herein, we present AAbAAC (AutoAntibodies and Autoimmunity Annotated Corpus), a corpus of 115 abstracts selected from PubMed, where we manually annotated entities and their relationships. First, AAbAAC was used to evaluate several methods on the task of named entity recognition (NER), and secondly, to fine-tune NER models. Our study demonstrates the utility of AAbAAC for information extraction in the domain of autoimmunity, showing expected improvement in NER performance after finetuning. This illustrates the value of small-scale annotation efforts for specialized domains and contributes to the computational study of autoimmunity.

Rethinking RAG in Long Videos: What to Retrieve and How to Use It?

重新思考长视频中的RAG:该检索什么以及如何使用?
Lee, Yuho, Shin, Jisu, Kim, Nicole Hee-Yeon, Bang, Jihwan, Lee, Juntae, Hwang, Kyuwoong, Porikli, Fatih, Song, Hwanjun
Abstract
Retrieval-augmented generation is moving beyond text into long, egocentric video, where systems must select query-relevant chunks across multiple modalities and temporal granularities. Yet progress in VideoRAG is limited by two gaps: existing benchmarks allow queries to be answered without the video, obscuring retrieval errors, and prior methods apply a single modality-granularity configuration per query, ignoring chunk-level variability. We address both by introducing V-RAGBench, a benchmark of $\langle$query, evidence chunk, answer$\rangle$ triplets that enables faithful, decoupled evaluation of retrieval and generation, and CARVE, a simple method that runs parallel retrievers across configurations and employs chunk-adaptive reranking to identify the winning configuration for each chunk. Each chunk then enters the generator under its winning configuration selected during retrieval, yielding an interleaved evidence form where the chunk-level decision propagates across both stages. CARVE outperforms eight recent VideoRAG baselines, with the chunks supplied to the generator interleaving multiple configurations rather than sharing a single one, a behavior unattainable by query-level methods.

检索增强生成正在从文本扩展到长时间的自我中心视频,其中系统必须选择跨多个模态和时间粒度的查询相关片段。然而,VideoRAG的进展受到两个方面的限制:现有基准允许在没有视频的情况下回答查询,从而掩盖了检索错误;而之前的方法对每个查询应用单一的模态-粒度配置,忽视了片段级的变异性。我们通过引入V-RAGBench来解决这两个问题,V-RAGBench是一个包含$ extlangle$query, evidence chunk, answer$ extrangle$三元组的基准,能够实现检索和生成的真实、解耦评估;同时提出了CARVE,这是一种简单的方法,通过在不同配置中并行运行检索器,并采用片段自适应重排序来识别每个片段的最佳配置。每个片段随后在检索过程中选择的最佳配置下进入生成器,形成一种交错的证据形式,使得片段级决策在两个阶段之间传播。CARVE的表现优于八个近期的VideoRAG基线,提供给生成器的片段交错了多种配置,而不是共享单一配置,这种行为是查询级方法无法实现的。

TerraBench: Can Agents Reason Over Heterogeneous Earth-System Data?

TerraBench:智能体能否对异构地球系统数据进行推理?
Nguyen, Dat Tien, Nguyen, Thao, Maani, Fadillah Adamsyah, Le, Huy M., Sheikh, Muhammad Umer, Saeed, Numan, Khan, Muhammad Haris, Khan, Salman
Abstract
Climate and environmental decision-making increasingly requires reasoning across heterogeneous inputs, including gridded physical data, satellite imagery, geospatial context, and simulator outputs. Weather and climate foundation models can forecast well, but do not reason interactively in language, while large language models (LLMs) reason in language but cannot operate directly on high-dimensional Earth-system data. As a result, real scientific workflows in Earth-science remain underserved. We introduce TerraBench, a benchmark for grounded Earth-science reasoning, built on TerraAgent, a ReAct-style executable framework that interleaves reasoning, tool calls, and observations to couple LLM planning with scientific tools for environmental retrieval, geospatial processing, simulation, and artifact-backed computation. TerraBench unifies analysis of Earth observation imagery, gridded data, GIS reasoning and simulation in a single executable interface, whereas prior benchmarks isolate these capabilities into narrow individual tasks. It is also the first in this space to pair process-level tool-use metrics with tolerance-aware numeric scoring. The benchmark comprises 403 extensive agentic tasks across three tracks (Fundamentals, Simulator-Grounded, and Document-Grounded Verification) and eight application domains with 24,500 verified execution steps. These results indicate that reliable Earth-science agents must go beyond tool access to coordinate heterogeneous workflows, parameterize tools precisely, and preserve artifact provenance.

气候和环境决策日益需要在异构输入之间进行推理,这些输入包括网格化的物理数据、卫星图像、地理空间上下文和模拟器输出。天气和气候基础模型能够进行良好的预测,但无法在语言中进行交互式推理,而大型语言模型(LLMs)能够进行语言推理,但无法直接处理高维的地球系统数据。因此,地球科学中的实际科学工作流程仍然得不到充分服务。我们介绍了TerraBench,这是一个基于TerraAgent的地球科学推理基准,TerraAgent是一个ReAct风格的可执行框架,它交错了推理、工具调用和观察,以将LLM规划与环境检索、地理空间处理、模拟和基于文献的计算的科学工具结合起来。TerraBench将地球观测图像、网格数据、地理信息系统(GIS)推理和模拟的分析统一在一个可执行接口中,而之前的基准将这些能力孤立为狭窄的单一任务。它也是该领域首个将过程级工具使用指标与容忍度感知的数值评分相结合的基准。该基准包括403个广泛的智能体任务,分为三个轨道(基础、模拟器基础和文档基础验证)和八个应用领域,具有24,500个经过验证的执行步骤。这些结果表明,可靠的地球科学智能体必须超越工具访问,协调异构工作流程,精确参数化工具,并保留文献来源。

Mental-R1: Aligning LLM Reasoning for Mental Health Assessment

Mental-R1:对齐大型语言模型推理以进行心理健康评估
Wang, Xin, Gao, Boyan, Yang, Yibo, Clifton, David A.
Abstract
Mental health problems such as anxiety, depression, and suicide remain urgent global challenges, where timely and accurate assessment is critical for effective intervention. Recently, large language models have been explored for mental health assessment. However, existing general-purpose post-training methods do not align with the cognitive processes of human assessment, which may lead to unreliable reasoning outcomes. To bridge this gap, we propose Cognitive Relative Policy Optimization (CRPO), a reinforcement learning framework tailored for the mental health domain. CRPO extends group relative policy optimization by integrating stage-dependent uncertainty modeling into the policy optimization process. Specifically, we introduce a stage-wise entropy regularization mechanism that encourages broad exploration in early reasoning phases and progressively enforces confident decision-making in later stages, mimicking the human cognitive shift from uncertainty to certainty. In addition, inspired by cognitive appraisal theory, we formalize cognitive reasoning stages, thereby guiding theory-grounded interpretable inference. Experiments on 8 mental health datasets show that CRPO achieves an average improvement of 10.4 percentage points in weighted F1-score over the best reinforcement learning baseline. Furthermore, the CRPO-trained model Mental-R1 demonstrates clear advantages compared with existing large language models on reasoning-intensive cases, suggesting that CRPO enhances reasoning capabilities for mental health assessment.

心理健康问题,如焦虑、抑郁和自杀,仍然是全球紧迫的挑战,及时和准确的评估对于有效干预至关重要。最近,大型语言模型被探索用于心理健康评估。然而,现有的通用后训练方法与人类评估的认知过程不一致,这可能导致不可靠的推理结果。为了解决这一问题,我们提出了认知相对策略优化(Cognitive Relative Policy Optimization, CRPO),这是一个专为心理健康领域量身定制的强化学习框架。CRPO通过将阶段依赖的不确定性建模整合到策略优化过程中,扩展了群体相对策略优化。具体而言,我们引入了一种阶段性熵正则化机制,鼓励在早期推理阶段进行广泛探索,并在后期阶段逐步强化自信决策,模拟人类从不确定性向确定性的认知转变。此外,受到认知评估理论的启发,我们形式化了认知推理阶段,从而指导基于理论的可解释推理。在8个心理健康数据集上的实验表明,CRPO在加权F1-score上比最佳强化学习基线平均提高了10.4个百分点。此外,经过CRPO训练的模型Mental-R1在推理密集型案例中与现有的大型语言模型相比显示出明显优势,表明CRPO增强了心理健康评估的推理能力。

Reasoning for Mobile User Experience with Multimodal LLMs: Task, Benchmark, and Approach

基于多模态大语言模型的移动用户体验推理:任务、基准和方法
Mao, Ruichao, Fang, Zhou, Guo, Teng, Yang, Hao, Li, Yaping, Peng, Shaohua, Huang, Maji, Lin, Xiaoyu, Liu, Shuoyang, Li, Xuepeng, Zhang, Yuyu, Rao, Hai
Abstract
User experience (UX) centered on usability, perceived consistency, and functional clarity is fundamental to real-world user interfaces (UI). The application of multimodal large language models (MLLMs) in the field of user interfaces is evolving rapidly, such as visual element grounding, graphical user interface (GUI) agents, and design-to-code generation. However, research efforts on evaluating UX based on UI screenshots are still immature. To address this, we propose UXBench, a novel multimodal benchmark consisting of 2,000 VQA data samples designed to assess MLLMs' ability to perform UI-based reasoning. UXBench includes 8 tasks based on real-world UI screenshots that require fine-grained diagnosis of UX issues across layout relationships, visual hierarchy, and content consistency. Our extensive evaluation of mainstream MLLMs shows that they remain fundamentally limited in their capacity for UI-based reasoning. The results underscore the need for further advancements in this area. To bridge this gap, we propose UI-UX, an MLLM based on Qwen3-VL-4B-Thinking foundation model and enhanced via reinforcement learning with two key innovations: a reward routing mechanism that dynamically balances perceptual understanding and logical reasoning during inference, and an asymmetric transition reward that suppresses redundant or insufficient reasoning steps. Experiments demonstrate that UI-UX achieves state-of-the-art (SOTA) performance on UXBench, attaining an accuracy of 0.7963 -- surpassing Claude-4.5-Sonnet's 0.6550 -- while exhibiting strong generalization across diverse UI tasks and maintaining low inference latency.

以可用性、感知一致性和功能清晰度为中心的用户体验(UX)是现实世界用户界面(UI)的基础。多模态大语言模型(MLLMs)在用户界面领域的应用正在迅速发展,例如视觉元素定位、图形用户界面(GUI)代理和设计到代码生成。然而,基于UI截图评估UX的研究仍然不够成熟。为了解决这一问题,我们提出了UXBench,这是一个新颖的多模态基准,包含2000个视觉问答(VQA)数据样本,旨在评估MLLMs在UI基础推理方面的能力。UXBench包括8个基于真实UI截图的任务,这些任务需要对布局关系、视觉层次和内容一致性进行细致的UX问题诊断。我们对主流MLLMs的广泛评估表明,它们在UI基础推理能力上仍然存在根本性的局限性。结果强调了在这一领域进一步发展的必要性。为弥补这一差距,我们提出了UI-UX,这是一个基于Qwen3-VL-4B-Thinking基础模型的MLLM,通过强化学习进行了增强,具有两个关键创新:一种奖励路由机制,在推理过程中动态平衡感知理解和逻辑推理,以及一种不对称转移奖励,抑制冗余或不足的推理步骤。实验表明,UI-UX在UXBench上达到了最先进的(SOTA)性能,准确率为0.7963,超过了Claude-4.5-Sonnet的0.6550,同时在多样化的UI任务中表现出强大的泛化能力,并保持低推理延迟。

Under What Conditions Can a Machine Become Genuinely Creative?

在什么条件下机器可以真正具备创造力?
Zeng, Yong
Abstract
Recent AI systems can generate texts, software architectures, hypotheses, designs, and scientific workflows that appear creative. This paper asks under what conditions a machine can become genuinely creative, and how human agency can be preserved within shared cognitive and creative environments. It develops a requirement framework derived from Designics, the science of meaning-bearing intentional change. The paper argues that genuine machine creativity should not be defined by output novelty, current performance, or transient architecture alone. Instead, creativity is understood as the structural transformation of incomplete situations through recursive intervention dynamics. On this view, it depends on ten requirements: environment representation, scoped perception, conflict identification, intervention capability, consequence observation, knowledge and environment update, rescoping, local-to-global unfolding, value-based scoping, and human-AI co-living. These are organized through the three laws of Designics: perception, conflict, and capability. The paper illustrates the computational tractability of these requirements through selected cyber-physical and cyber-biological studies, including recursive element extraction, autonomous mesh generation, and neurophysiological and workload analysis. It then treats open-ended systems, automated discovery frameworks, self-modifying agents, foundation models, and agentic workflows as pressure cases: they demonstrate powerful generative means but do not by themselves establish genuine machine creativity. Finally, the paper argues that proactive AI ethics is internal to genuine machine creativity rather than an after-the-fact filter. Value-based scoping and human-AI co-living must shape how creative machines perceive environments, identify conflicts, select interventions, observe consequences, update knowledge, and rescope future action.

ARMOR-MAD: Adaptive Routing for Heterogeneous Multi-Agent Debate in Large Language Model Reasoning

ARMOR-MAD:异构多智能体辩论在大型语言模型推理中的自适应路由
Niu, Fuqiang, Zhang, Bowen
Abstract
Multi-agent debate (MAD) can improve large language model reasoning, but fixed debate pipelines often waste computation and can amplify correlated errors among similar agents. We propose ARMOR-MAD, a training-free heterogeneous MAD framework that treats debate as conditional computation. ARMOR-MAD combines three components: Pre-debate Agreement Routing (PAR) decides whether independently generated Round-0 answers require debate; Early Agreement Stopping Evaluator (EASE) stops debate after convergence; and Semantic Outlier Detection (SOD) down-weights abnormal final answers during aggregation. Across MATH Level 5, GSM8K, MMLU, and MMLU-Pro, ARMOR-MAD consistently improves over fixed-round heterogeneous debate with the same model pool, reaching 65.5\%, 96.5\%, 90.0\%, and 81.5\% accuracy, respectively. The results suggest that genuine model heterogeneity and agreement-based control are both important for making MAD more accurate and efficient.

A Minimal Model of Bounded Trade-Off Screening in Multi-Attribute Choice

多属性选择中有限权衡筛选的最小模型
Dubey, Manisha, Sarkar, Anirban, Ramamoorthy, Subramanian
Abstract
Human decision-making often involves choosing between multi-attribute alternatives, yet classical models assume fully compensatory utility aggregation despite evidence that people reject options with poor performance on critical attributes. We propose a bounded trade-off reasoning framework in which decisions are governed by a screening process that evaluates the balance between gains and losses across attributes. The model introduces a trade-off tolerance parameter that controls acceptable imbalance and can vary across contexts. Through simulation, we show that this mechanism produces preference patterns that differ from standard utility-based models and captures context-dependent variation in trade-off behavior. These results establish bounded trade-off screening as a plausible computational mechanism for multi-attribute choice and generate testable predictions for future behavioral studies.

Hallucination in Medical Imaging AI: A Cross-Modality Analytical Framework for Taxonomy, Detection, and Mitigation under Regulatory Constraints

医疗影像人工智能中的幻觉:在监管约束下的跨模态分析框架用于分类、检测和缓解
Alshahrani, Omar, Behzad, Muzammil
Abstract
AI systems are being deployed across medical imaging faster than their failure modes are understood. At this point in time, the failure of greatest clinical concern is hallucination: clinically plausible but factually incorrect outputs, including fabricated anatomical structures, missed findings, incorrect laterality, and invented measurements in generated reports, with direct consequences, for example, for biopsy decisions, staging, and treatment planning. This structured narrative synthesizes peer-reviewed studies, benchmark datasets, and FDA regulatory guidance across five imaging modalities to produce a cross-modality analysis of hallucination taxonomy, etiology, detection, and mitigation. Specifically, we address three questions in this study: (1) how can existing taxonomies be unified across modalities?, (2) how do medical-specialized foundation models hallucinate less than general-purpose ones?, and (3) which mitigation strategies are effective and compatible with FDA lifecycle oversight? We note that three taxonomic frameworks together cover the imaging pipeline in a way no single framework does alone. We also highlight that general-purpose foundation models outperform medical-specialized models on hallucination-specific benchmarks, indicating that narrow domain fine-tuning can introduce overfitting-induced confabulation. At the same time, the oversight of radiologists remains essential; for instance, a very high percentage of of AI-generated flags required expert correction before clinical use. Physics-informed architectural constraints, Chain-of-Thought prompting, and human-in-the-loop safeguards each address different failure modes and is effective when combined. All findings are mapped to the FDA's Total Product Lifecycle and Predetermined Change Control Plan frameworks, which treat hallucination management as a lifecycle obligation rather than a pre-deployment checklist.

LLM-as-an-Investigator: Evidence-First Reasoning for Robust Interactive Problem Diagnosis

LLM作为调查者:以证据为先的稳健互动问题诊断
Marozzo, Fabrizio, Liò, Pietro
Abstract
Large language models (LLMs) are increasingly used as interactive assistants for technical problem solving. However, when users provide incomplete descriptions or plausible but unverified explanations, LLMs may prematurely align with these assumptions and propose solutions before collecting sufficient evidence. We refer to this behavior as user-driven sycophancy: the tendency of an LLM to reinforce a user-provided hypothesis instead of testing alternative explanations. This paper introduces LLM-as-an-Investigator, an evidence-first agentic AI methodology for robust problem diagnosis. The approach is implemented through a Solution Investigator Agent, which estimates the ambiguity of an initial problem description, generates candidate hypotheses, asks targeted clarification questions, and updates hypothesis probabilities after each answer. Rather than producing an immediate response, the agent continues the investigation until the evidence makes one candidate explanation stronger than the alternatives. To evaluate the approach, we build a benchmark from solved technical forum threads in mechanical, electrical, and hydraulic domains. We use a three-agent evaluation pipeline in which a Problem-Solution Extractor Agent converts solved threads into structured cases, a Ground-Truth Evaluator Agent simulates the user while hiding the known solution, and the tested assistant attempts to recover the solution through dialogue. The experiments compare standard assistants, reasoning-oriented LLMs, and the proposed investigator-based model across LLM backbones. In addition to diagnostic accuracy, we analyze how standard assistants follow misleading user hypotheses in diagnostic cases. The results show that the proposed approach identifies the problem more accurately than direct prompting and reasoning-only baselines, while its evidence-first protocol helps reduce user-induced conversational bias.

大型语言模型(LLMs)越来越多地被用作技术问题解决的互动助手。然而,当用户提供不完整的描述或合理但未经验证的解释时,LLMs可能会过早地与这些假设对齐,并在收集足够证据之前提出解决方案。我们将这种行为称为用户驱动的谄媚:LLM强化用户提供的假设而不是测试替代解释的倾向。本文介绍了LLM作为调查者(LLM-as-an-Investigator),一种以证据为先的自主人工智能方法,用于稳健的问题诊断。该方法通过解决方案调查代理(Solution Investigator Agent)实施,该代理评估初始问题描述的模糊性,生成候选假设,提出针对性的澄清问题,并在每个回答后更新假设概率。代理并不立即产生响应,而是继续调查,直到证据使一个候选解释比其他解释更强。为了评估该方法,我们从机械、电气和液压领域的已解决技术论坛线程中构建了基准。我们使用三代理评估管道,其中问题-解决方案提取代理(Problem-Solution Extractor Agent)将已解决的线程转换为结构化案例,真实情况评估代理(Ground-Truth Evaluator Agent)模拟用户,同时隐藏已知解决方案,而被测试的助手则尝试通过对话恢复解决方案。实验比较了标准助手、面向推理的LLMs和所提出的基于调查者的模型在LLM骨干上的表现。除了诊断准确性外,我们还分析了标准助手在诊断案例中如何遵循误导性的用户假设。结果表明,所提出的方法比直接提示和仅推理的基线更准确地识别问题,同时其以证据为先的协议有助于减少用户引起的对话偏差。

Brick: Spatial Capability Routing for the Mixture-of-Models (MoM) Paradigm

Brick:混合模型(MoM)范式的空间能力路由
Massa, Francesco, Cristofanilli, Marco
Abstract
Defining query difficulty is one of the hardest problems in deployment engineering. Existing LLM routers rely on surface features such as domain labels, keywords, and token count, ignoring the within-domain variance that actually determines model success. Frontier models cost ten to one hundred times more than local open-weight models, so at production scale even small per-request savings become a direct cloud-bill lever. We present Brick, a multimodal router that scores each model on six capability dimensions, combines this with a per-query difficulty estimate, and dispatches via a cost-penalized geometric rule. A continuous preference knob lets operators slide between max-quality and max-saving profiles at deploy time. On a benchmark of 5,504 queries, Brick at max-quality reaches 76.98% accuracy, beating the best single model (75.02%) and all tested routers. At a neutral cost-quality profile, Brick achieves 74.11% accuracy at 4.71x lower cost than always using the strongest model. At min-cost, it cuts cost 22.15x with 11.85 points accuracy loss. Median latency drops from 51.2s to 22.8s.

EPIG: Emotion-Based Prompting for Personalised Image Generation

EPIG:基于情感的个性化图像生成提示
Othmen, Emna, Landolsi, Mohamed Yassine, Romdhane, Lotfi Ben
Abstract
Text-to-image diffusion models have achieved impressive results in synthesizing high-quality images from natural language prompts. However, commonly used prompting strategies remain relatively generic, limiting the model's ability to accurately express emotional intent and nuanced affective attributes. This work proposes EPIG, a method that enhances emotional expressiveness at the prompt level prior to image generation. Grounded in psychologically informed emotion representations (valence-arousal) and leveraging structured, role-aware prompt enrichment, EPIG enriches emotion-related components of prompts without modifying or retraining the image generation backbone. The resulting emotion-aware prompts guide the generative process toward more emotionally coherent visual outputs, with particular effectiveness in controlling arousal. EPIG is lightweight, training-free, and well suited for resource-constrained and personalized image generation scenarios. Experimental results on a benchmark of 10 diverse prompts show that EPIG reduces mean arousal error compared to strong baselines, including naive insertion and LLM-based prompt expansion, with reductions of 14% and 12%, respectively. These improvements are statistically significant. EPIG also preserves valence alignment and semantic consistency, as measured by CLIPScore and supported by ablation studies. The effect is more pronounced on prompts containing explicit subjects such as humans, children, or animals, where the reduction reaches 17%, highlighting the subject-sensitive behavior of the proposed method.

Multi-Field Hybrid Retrieval-Augmented Generation for Maritime Accident Root Cause Analysis

多领域混合检索增强生成用于海事事故根本原因分析
Kim, Seongjin, Kim, Sungil
Abstract
Maritime accident adjudication reports contain critical tribunal findings for root cause analysis (RCA), yet retrieving relevant precedents and drafting consistent reports from decades of records remains labor-intensive. This paper proposes a multi-field hybrid retrieval-augmented generation (RAG) framework for automated maritime RCA, utilizing a comprehensive dataset of 13,329 Korea Maritime Safety Tribunal (KMST) reports (1971-2025). We transform raw adjudications into a structured knowledge base of "incident cards", indexing three distinct fields-Summary, Causes, and Disposition-alongside a hierarchical L1/L2 cause taxonomy. Our retrieval strategy employs a field-aware hybrid approach, fusing sparse and dense rankings via Reciprocal Rank Fusion (RRF). Given the lack of large-scale expert relevance labels, we evaluate retrieval performance using ceiling-normalized recall and nDCG based on a metadata-derived proxy relevance score. Experimental results demonstrate that our proposed retrieval significantly outperforms baseline methods, improving NormRecall@100 from 0.18 to 0.55. Furthermore, grounding the generator on the retrieved precedents enhances RCA generation quality over an LLM-only baseline, increasing the LLM-as-a-judge score from 3.34 to 3.72. These findings suggest that field-aware RAG can substantially streamline maritime safety investigation workflows by enabling faster precedent search and more consistent, evidence-based RCA drafting.

MOSAIC: Modality-Specific Adaptation for Incremental Continual Learning in Parkinson's Disease Gait Assessment

MOSAIC:用于帕金森病步态评估的增量持续学习的模态特定适应
Zeng, Minlin, Zhou, Zhipeng, Qiu, Yang, McKeown, Martin J., Shen, Zhiqi
Abstract
Gait-based Parkinson's disease assessment increasingly relies on heterogeneous sensors, but clinical systems rarely collect all modalities simultaneously. New sensors may arrive through device upgrades, protocol changes, or multi-center deployment, while historical patient data are often unavailable because of privacy and storage constraints. This modality-incremental setting faces three challenges: unreliable cross-modal distillation, modality-specific statistical shifts, and reduced plasticity after preservation. We propose MOSAIC, a compact continual learning framework. First, we identify the Toxic Teacher phenomenon and introduce Modality-Specific Warm-Up to stabilize newly learned modality representations before distillation. Second, we propose a statistics-decoupled MSBN architecture that isolates sensor statistics while maintaining a shared semantic backbone. Third, we design a curriculum-guided repulsive objective for Plasticity Recovery, preserving legacy knowledge while recovering modality-specific capacity. Experiments on three multimodal Parkinson's gait datasets show that MOSAIC improves final performance and mitigates forgetting.

基于步态的帕金森病评估日益依赖异构传感器,但临床系统很少同时收集所有模态。新传感器可能通过设备升级、协议变更或多中心部署而出现,而由于隐私和存储限制,历史患者数据通常不可用。这种模态增量设置面临三个挑战:不可靠的跨模态蒸馏、模态特定的统计偏移以及在保留后减少的可塑性。我们提出了MOSAIC,一个紧凑的持续学习框架。首先,我们识别了有毒教师现象,并引入模态特定的热身策略,以在蒸馏之前稳定新学习的模态表示。其次,我们提出了一种统计解耦的MSBN架构,该架构在保持共享语义骨干的同时,隔离传感器统计信息。第三,我们设计了一种课程引导的排斥目标,以实现可塑性恢复,保留遗留知识的同时恢复模态特定的能力。在三个多模态帕金森病步态数据集上的实验表明,MOSAIC提高了最终性能并减轻了遗忘。项目代码可在以下链接获取:https://github.com/minlinzeng/MOSAIC_Modality-Specific-Adaptation-for-Incremental-Continual-Learning-in-PD-Gait-Assessment.git

From Verdict to Process: Agentic Reinforcement Learning for Multi-Stage Fact Verification

从裁决到过程:用于多阶段事实验证的自主强化学习
Yang, Rongxin, He, Shenghong, Zhu, Siyuan, Yu, Chao
Abstract
Recent approaches combining Large Language Models (LLMs) with retrieval-augmented reasoning have shown promise for automated fact verification. To process complex claims, these verification pipelines typically execute multi-stage workflows that coordinate tightly coupled modules, including claim decomposition, evidence gathering, and verdict prediction. However, existing methods optimize individual stages in isolation or rely on fixed heuristics, which limits adaptive coordination among stages and can lead to suboptimal outcomes. In this work, we propose ProFact, an agentic reinforcement learning framework for end-to-end optimization of multi-stage fact verification trajectories. ProFact trains a unified policy to coordinate claim decomposition, evidence seeking, answer generation, and verdict prediction. To address the sparse and delayed supervision provided by final veracity labels, ProFact introduces process-aware rewards that provide stage-level learning signals throughout the verification process. Empirical evaluation shows that ProFact consistently outperforms strong baselines in both verification performance and inference efficiency. These results highlight the effectiveness of process-aware trajectory optimization for multi-stage fact verification.

最近将大型语言模型(LLMs)与检索增强推理相结合的方法在自动化事实验证方面显示出良好的前景。为了处理复杂的主张,这些验证流程通常执行多阶段工作流,紧密协调包括主张分解、证据收集和裁决预测等模块。然而,现有方法往往孤立地优化各个阶段或依赖固定的启发式方法,这限制了各阶段之间的自适应协调,可能导致次优结果。在本研究中,我们提出了ProFact,一个用于多阶段事实验证轨迹端到端优化的自主强化学习框架。ProFact训练一个统一的策略,以协调主张分解、证据寻求、答案生成和裁决预测。为了解决最终真实性标签提供的稀疏和延迟监督问题,ProFact引入了过程感知奖励,在整个验证过程中提供阶段级学习信号。实证评估表明,ProFact在验证性能和推理效率方面始终优于强基线。这些结果突显了过程感知轨迹优化在多阶段事实验证中的有效性。

ERTS: Adversarial Robustness Testing of Ethical AI via Semantic Perturbation in a Bounded Consequence Space

ERTS:通过语义扰动在有限后果空间中对伦理人工智能进行对抗鲁棒性测试
Chaudhari, Pratyush
Abstract
As AI systems are deployed in high-stakes ethical contexts such as healthcare triage, autonomous vehicle control, and employment screening, formal methods for evaluating their robustness against adversarial manipulation of ethical reasoning remain underdeveloped. This paper introduces the Ethical Robustness Testing System (ERTS), a closed-pipeline framework that: (1) encodes ethical dilemmas into a 22-dimensional Ethical Consequence Space (ECS) grounded in established ethical theory; (2) applies 17 semantic perturbation functions subject to 6 validity constraint classes including a novel semantic coherence constraint; (3) measures decision deviation via a 4-component Ethical Instability Index (EII); and (4) produces domain-adaptive pre-deployment robustness assessment verdicts. We evaluate 4 structured baseline models and 2 production LLMs (Gemini 2.0 Flash and Llama 3.2) across 50 ethical scenarios spanning 8 deployment domains, generating 1,500 adversarial test cases. Results demonstrate that only 33% of models achieve assessment clearance, with the local Llama-3.2 model proving particularly vulnerable to fairness corruption and information degradation attacks (ERS = 0.737). To the best of our knowledge, no existing framework combines a bounded ethical consequence space, semantic coherence constraints, and domain-adaptive assessment in a single adversarial testing pipeline.

Physics-Guided Spatiotemporal Learning for Coastal Wave Peak Period Estimation from Video

基于物理引导的时空学习用于从视频中估计沿海波峰周期

Abstract
Wave parameters in the nearshore are crucial for coastal engineering, shoreline protection, marine hazard assessment, and coastal management for climate resilience. Traditional monitoring systems like buoys and radar platforms offer accurate monitoring but can have high installation and maintenance expenses and limited spatial coverage. Passive ocean monitoring using video has been achieved by leveraging deep learning, however, many methods are not physically interpretable, feasible, and validated for oceanography. In thiswork, a Physics-Guided Deep Spatiotemporal Learning Framework for direct estimation of nearshore wave peak periods from passive coastal video stream is proposed. The framework combines automated temporal-variance based region-of-interest detection, multi-stage Sim-to-Real transfer learning, and physics-informed regularization to enhance the predictive accuracy and physical consistency. A variety of spatiotemporal architectures were assessed, such as transformer-based and recurrent-convolutional ones, alongside synthetic pretraining,silver-label adaptation, and expert fine-tuning. The results show that transformer-based architectures outperformed in terms of the accuracy of the instantaneous prediction, while lightweight recurrent-convolutional architectures achieved higher temporal stability and operational oceanographic skill. Ablation studies also demonstrated the benefits of physics-guided regularization in terms of trend-following consistency, and physically implausible predictions. Explainability auditing also helped to focus attention in hydrodynamically active surf-zone regions and showed good agreement with the physically derived wave propagation behavior. In general, the proposed framework shows the promise of physics-guided video-based deep learning systems for long-term coastal wave monitoring that are cost-efficient and operationally feasible.

ReSum: Synergizing LLM Reasoning and Summarization with Reinforcement Learning

ReSum:通过强化学习协同大语言模型的推理与摘要
Wang, Xucong, Ma, Ziyu, Wang, Yong, Yang, Shidong, Huang, Hailang, Li, Renda, Wang, Pengkun, Chu, Xiangxiang
Abstract
Reinforcement Learning with Verifiable Rewards (RLVR) is a central technique for improving long-horizon reasoning in Large Language Models (LLMs). However, existing RLVR methods often encourage unnecessarily long reasoning rollouts, which can degrade reasoning coherence and exhaust the available context budget. Existing approaches to long-context organization often depend on external mechanisms to organize rollouts, rather than enabling the model to manage its own reasoning trajectory. To address this limitation, we propose ReSum, a novel RLVR framework that enables LLMs to compress and organize their reasoning trajectories through self-summarization. Our pilot studies show that self-summarization stabilizes generation by lowering token-level entropy, and that introducing a ``summarization'' phrase can substantially mitigate errors propagated from an incorrect rollout prefix. Motivated by these findings, ReSum adopts a summarization-aware adaptive rollout mechanism that contrastively evaluates whether self-summarization benefits the ongoing reasoning process. Specifically, when the model spontaneously triggers self-summarization, ReSum masks the summarization phrase to create a contrastive branch; for non-summarization positions, it instead randomly injects the phrase to create a matched branch. We further design a summarization-aware advantage to enable finer-grained comparison between contrastive rollout trajectories. Extensive experiments show that ReSum improves performance at an average of 4\% while reducing rollout length by 18.6\%.

可验证奖励的强化学习(Reinforcement Learning with Verifiable Rewards, RLVR)是提升大语言模型(Large Language Models, LLMs)长时间推理能力的核心技术。然而,现有的RLVR方法往往鼓励不必要的长推理展开,这可能会降低推理的连贯性并耗尽可用的上下文预算。现有的长上下文组织方法通常依赖于外部机制来组织推理展开,而不是让模型自行管理其推理轨迹。为了解决这一局限性,我们提出了ReSum,一个新颖的RLVR框架,使LLMs能够通过自我摘要来压缩和组织其推理轨迹。我们的初步研究表明,自我摘要通过降低令牌级别的熵来稳定生成,并且引入“摘要”短语可以显著减轻从错误的推理前缀传播的错误。基于这些发现,ReSum采用了一种摘要感知的自适应推理机制,对比评估自我摘要是否有利于正在进行的推理过程。具体而言,当模型自发触发自我摘要时,ReSum会屏蔽摘要短语以创建对比分支;对于非摘要位置,则随机注入该短语以创建匹配分支。我们进一步设计了一种摘要感知的优势,以便在对比推理轨迹之间进行更细粒度的比较。大量实验表明,ReSum在提高性能的同时,平均提升4%,并将推理长度减少了18.6%。

Can I Buy Your KV Cache?

我可以购买你的 KV 缓存吗?
Zhang, Luoyuan
Abstract
Right now, across the world, AI agents are repeating the same absurd act: to read one document, they each recompute it from scratch. Every agent re-runs prefill, the most compute-intensive step a large model takes, over identical text, only to rebuild a key-value (KV) cache identical to the one the agent before it just built. The same answer, computed a million times. We make a proposal that is almost offensively simple: compute it once. Let a publisher precompute a document's KV cache, and let every other agent buy the right to load it and skip prefill. It works, and it is token-exact: loading a precomputed KV and continuing matches prefilling from scratch (24/24 greedy tokens, and at the logits level), with no accuracy cost. On Qwen3-4B, reuse is 9-50x cheaper in compute than prefill, and the gap widens with length (prefill's attention scales with L^2), so a single reuse already pays it back. Then the part that matters: where the KV lives. Shipping it fails, because KV is nearly incompressible, so per-load egress costs more than the prefill it saves. Hosting it provider-side, exactly as production prompt-caching works, removes egress entirely. The size of the prize is set by our measured compute saving: serving one hot 3774-token document to 80M agents costs ~$1.5M to re-prefill but only ~$0.03M of reuse compute (49.7x less). The 0.1x cache-read tariff APIs charge passes a 10x discount to users while sitting inside this measured envelope, so the 10x is a floor that the measured ~50x compute saving clears, and the gap to the physical ~50x is provider margin: millions of dollars per popular document. We frame the resulting agent-native prefill CDN and leave lossless KV compression and a cross-party payment layer as the open problems.

目前,在全球范围内,人工智能代理正在重复同样荒谬的行为:为了读取一份文档,它们各自从头开始重新计算。每个代理在相同的文本上重新运行预填充(prefill),这是大型模型所需的计算最密集的步骤,仅仅是为了重建一个与前一个代理刚刚构建的相同的键值(KV)缓存。相同的答案,被计算了一百万次。我们提出了一个几乎令人震惊的简单方案:只计算一次。让出版商预先计算文档的 KV 缓存,让其他每个代理购买加载它的权利,从而跳过预填充。这是可行的,并且是逐字精确的:加载一个预计算的 KV 并继续操作与从头开始的预填充相匹配(24/24 贪婪令牌,并且在 logits 级别),没有准确性损失。在 Qwen3-4B 上,重用的计算成本比预填充便宜 9-50 倍,并且随着长度的增加差距会扩大(预填充的注意力与 L^2 成比例),因此单次重用已经能够收回成本。然后是重要的部分:KV 存放的位置。运输它是失败的,因为 KV 几乎不可压缩,因此每次加载的出口成本超过了它所节省的预填充成本。将其托管在提供方侧,正如生产提示缓存的工作方式,完全消除了出口成本。奖赏的规模由我们测量的计算节省设定:为 8000 万个代理提供一份热的 3774 令牌文档的成本约为 150 万美元用于重新预填充,但仅需约 3 万美元的重用计算(少 49.7 倍)。0.1 倍缓存读取收费的 API 在这个测量范围内向用户传递了 10 倍的折扣,因此 10 倍是一个底线,而测量的约 50 倍计算节省清除了这个底线,物理约 50 倍的差距是提供方的利润:每个热门文档数百万美元。我们构建了结果代理原生的预填充内容分发网络(CDN),并将无损 KV 压缩和跨方支付层留作开放问题。

Abstract
Computer-Aided Design is pivotal in modern manufacturing, yet existing automated methods predominantly rely on open-loop, one-shot generation, creating a mismatch with iterative real-world practices. In this paper, we present IterCAD, a unified multimodal agent framework for closed-loop, interactive CAD generation and editing. We formulate the task as a multi-turn interaction between a multimodal agent and an executable CAD sandbox, covering three tasks: Drawing-to-Code, Text-to-Code, and Interactive Editing. To support this, we develop a data synthesis pipeline incorporating advanced industrial manufacturing features to generate standard-compliant multi-view engineering drawings, complex code-editing tasks, and high-fidelity interaction trajectories. We optimize the agent via progressive SFT followed by geometry-aware reinforcement learning with viable-prefix masking to enhance code executability and geometric fidelity. Finally, we introduce the IterCAD-Bench evaluation suite and propose the Chamfer Distance Tolerance-Recall (CD-TR) curve alongside its AUC-TR metric, establishing a survivor-bias-free standard that unifies code validity and geometric precision. Extensive experiments demonstrate that IterCAD achieves highly competitive performance across multiple benchmarks, significantly outperforming existing approaches in both code executability and geometric precision, while exhibiting superior capabilities in closed-loop iterative refinement.

A Quantitative Experimental Repeated Measures Study of Training Dynamics in a Small Llama Style Language Model Under a Compute-Aware Token Budget

在计算感知令牌预算下小型Llama风格语言模型训练动态的定量实验重复测量研究
Dwyer, Joe
Abstract
This study examines training dynamics in a small Llama-style language model trained under a fixed, compute-constrained token budget. Rather than evaluating efficiency solely through endpoint performance, the study uses a quantitative experimental repeated measures design to analyze how validation loss, validation perplexity, rolling volatility, backslide behavior, spike behavior, and between-seed variability change across token-based training intervals. Six independent training runs were conducted on a 4.26-million-parameter model using the TinyStories corpus, CPU-based full-precision training, and a target budget of approximately 20 million cumulative training tokens. Metrics were collected across 21 intervals, producing 126 seed-by-interval observations. Repeated measures ANOVA showed statistically significant interval effects for validation loss, validation perplexity, and rolling volatility. Descriptive trajectories revealed rapid early improvement followed by non-monotonic degradation during later training intervals. Mean validation loss decreased from 8.3552 at initialization to 2.7996 near 4 million tokens, but increased to 3.9010 by the final checkpoint. Validation perplexity followed the same pattern, falling sharply early in training before rising later. Derived telemetry further showed recurrent validation-loss backslides and no interval-summary evidence of a stable phase under the predefined criteria. These findings suggest that compute-aware language model evaluation should examine training trajectories rather than endpoint metrics alone. In constrained compute settings, additional token exposure may increase computational cost without producing proportional generalization gains, and interval-level telemetry can reveal instability, regression, and diminishing returns that final metrics may obscure.

MiniMax Sparse Attention

MiniMax 稀疏注意力
Lai, Xunhao, Xu, Weiqi, Yang, Yufeng, Chen, Qiaorui, Xu, Yang, Zeng, Lunbin, Li, Xiaolong, Sun, Haohai, Zhu, Haichao, Zhang, Vito, Zhao, Pengyu
Abstract
Ultra-long-context capability is becoming indispensable for frontier LLMs: agentic workflows, repository-scale code reasoning, and persistent memory all require the model to jointly attend over hundreds of thousands to millions of tokens, yet the quadratic cost of softmax attention makes this untenable at deployment scale. We introduce MiniMax Sparse Attention (MSA), a blockwise sparse attention built upon Grouped Query Attention (GQA). A lightweight Index Branch scores key-value blocks and independently selects a Top-k subset for each GQA group, enabling group-specific sparse retrieval while maintaining efficient block-level execution; the Main Branch then performs exact block-sparse attention over only the selected blocks. Designed around a principle of simplicity and scalability, MSA is deliberately streamlined, making it straightforward to deploy efficiently across a broad range of GPUs. To translate sparsity into practical speedups, we co-design MSA with a GPU execution path that uses exp-free Top-k selection and KV-outer sparse attention to improve tensor-core utilization under block-granular access. On a 109B-parameter model with native multimodal training, MSA performs on par with GQA while reducing per-token attention compute by 28.4x at 1M context. Paired with our co-designed kernel, MSA achieves 14.2x prefill and 7.6x decoding wall-clock speedups on H800. Our inference kernel is available at: https://github.com/MiniMax-AI/MSA. A production-grade natively multimodal model powered by MSA has been publicly released at: https://huggingface.co/MiniMaxAI/MiniMax-M3.

超长上下文能力正成为前沿大型语言模型(LLMs)不可或缺的特性:代理工作流、库规模的代码推理和持久内存都要求模型能够共同关注数十万到数百万个标记,然而,softmax 注意力的二次成本使得在部署规模上难以实现。我们提出了 MiniMax 稀疏注意力(MSA),这是一种基于分组查询注意力(Grouped Query Attention, GQA)的块状稀疏注意力。轻量级的索引分支对键值块进行评分,并为每个 GQA 组独立选择一个 Top-k 子集,从而实现组特定的稀疏检索,同时保持高效的块级执行;主分支则仅对选定的块执行精确的块稀疏注意力。MSA 设计遵循简单性和可扩展性的原则,经过精心简化,使其在广泛的 GPU 上高效部署变得简单。为了将稀疏性转化为实际的加速效果,我们与 GPU 执行路径共同设计 MSA,采用无指数的 Top-k 选择和 KV-外部稀疏注意力,以提高在块粒度访问下的张量核心利用率。在一个拥有 109B 参数的模型上,经过原生多模态训练,MSA 的性能与 GQA 相当,同时在 1M 上下文下将每个标记的注意力计算减少了 28.4 倍。配合我们共同设计的内核,MSA 在 H800 上实现了 14.2 倍的预填充和 7.6 倍的解码时钟速度提升。我们的推理内核可在以下链接获取:https://github.com/MiniMax-AI/MSA。由 MSA 驱动的生产级原生多模态模型已在以下链接公开发布:https://huggingface.co/MiniMaxAI/MiniMax-M3。

Neuro-Symbolic Agents for Regulated Process Automation: Challenges and Research Agenda

神经符号智能体在受监管过程自动化中的应用:挑战与研究议程

Abstract
LLM-based agents are entering regulated industries where they automate judgment intensive quality management processes. We argue that symbolic structures already embedded in these domains, including regulations, typed process models, and compliance constraints, should be treated not merely as external monitoring mechanisms but as core architectural components that shape the agent's decision-making and behavior. We propose compliance-by-construction as a complementary paradigm to guardrail-based monitoring: a structural foundation that prevents control-flow violations, while guardrails remain essential for catching semantic errors. We identify a structured set of neuro-symbolic research challenges on foundational and capability level and show that addressing them jointly enables compliance-by-construction. We call on the neuro-symbolic community to engage with regulated process automation as a high impact research domain.

Optimizing Appliance Scheduling for Solar Energy Management Using Metaheuristic Algorithms

使用元启发式算法优化太阳能管理的家电调度
Ahmed, Hiba, Brownlee, Alexander E. I., Adair, Jason, Powers, Simon T.
Abstract
Renewable energy is essential for meeting future energy demands; however, solar energy generation, which occurs only during daylight hours often does not align with household consumption patterns. Appliances such as cookers, washing machines, and dryers are typically operated according to user preferred schedules rather than solar energy availability, creating a scheduling optimization problem. The objective is to determine optimal appliance start times to maximize renewable energy utilization while minimizing user inconvenience and adhering to system constraints. This paper presents a metaheuristic approach using Iterated Local Search (ILS) and Simulated Annealing (SA) to optimize appliance start times, while considering appliance operating durations, power consumption, inverter limit, battery state of charge constraints, and solar generation forecasts. Unlike most existing work, the scheduling is extended beyond a single day to accommodate unfinished tasks from previous days (spillover), ensuring operational continuity and enabling sequential operation across multiple days. Experimental results show that the sequential multi-day scheduling framework effectively manages system constraints while ensuring user convenience under exclusive solar generation. These findings also open opportunities for future research on multi-objective trade-offs between investment in equipment of various sizes, return on that investment, and user satisfaction.

Evaluation Sovereignty in Metadata-Driven Classification: A Multi-Track Framework for Weakly Supervised Information Systems

元数据驱动分类中的评估主权:一种针对弱监督信息系统的多轨框架
Vasquez, Raymond
Abstract
Evaluation in machine learning is typically treated as a neutral measurement process. However, in operational information systems, evaluation outcomes are often conditioned by the processes used to generate labels. This paper does not seek to improve classification performance. Instead, it examines the validity of performance measurement under differing label-authority regimes. This issue is particularly relevant in large-scale metadata-driven systems, where labels are often incomplete, inconsistent, or weakly supervised. We introduce evaluation sovereignty, defined as the degree to which performance metrics are independent of label authority and supervision regime, and propose a multi-track evaluation framework that systematically varies training and evaluation label sources. Using hierarchical multi-label classification on large-scale scientific metadata, we demonstrate that models exhibiting strong performance under operational ("silver") evaluation degrade substantially under independent ("gold") evaluation, particularly for fine-grained classification. For example, Micro-F1 decreases from approximately 0.54 to 0.03. Notably, ranking-based metrics remain above baseline, revealing a divergence between latent model signal and classification validity. These findings suggest that commonly reported performance metrics may reflect alignment with labeling processes rather than true predictive capability. We therefore reconceptualize evaluation validity as a system-level property shaped by label governance and provide a practical methodology for auditing intelligent systems operating under weak supervision.

在机器学习中,评估通常被视为一个中立的测量过程。然而,在操作性信息系统中,评估结果往往受到生成标签过程的影响。本文并不寻求提高分类性能,而是考察在不同标签权威体制下性能测量的有效性。这个问题在大规模元数据驱动系统中尤为重要,因为这些系统中的标签往往是不完整、不一致或弱监督的。我们引入了评估主权的概念,定义为性能指标在多大程度上独立于标签权威和监督体制,并提出了一种多轨评估框架,系统地变化训练和评估标签来源。通过对大规模科学元数据进行层次多标签分类,我们展示了在操作性(“银”)评估下表现强劲的模型在独立(“金”)评估下显著退化,尤其是在细粒度分类中。例如,Micro-F1 从约 0.54 降至 0.03。值得注意的是,基于排名的指标仍然高于基线,揭示了潜在模型信号与分类有效性之间的差异。这些发现表明,常报告的性能指标可能反映了与标签过程的一致性,而非真实的预测能力。因此,我们重新概念化评估有效性为一种由标签治理塑造的系统级属性,并提供了一种实用的方法论,用于审计在弱监督下运行的智能系统。

Why Sampling Is Not Choosing: Intentionality, Agency, and Moral Responsibility in Large Language Models

为何采样不是选择:大型语言模型中的意图性、能动性与道德责任
Keshet, Joseph
Abstract
Recent advances in large language models (LLMs) have prompted claims that such systems exhibit agency or qualify as moral agents. This paper argues that these attributions are misguided. We maintain that moral responsibility requires commitment-bearing agency grounded in intrinsic intentionality and self-attributed action, and that such agency constitutes the form of free will relevant to responsibility. Although LLMs generate coherent and normatively evaluable outputs, their operation is fully characterized by probabilistic input-output mappings learned from data. Their apparent intentionality is derived rather than intrinsic, and their outputs are neither owned as commitments nor guided by reasons. Variability introduced by stochastic sampling does not amount to choice or authorship.

近期大型语言模型(LLMs)的进展引发了关于这些系统是否展现能动性或是否可以被视为道德代理人的讨论。本文认为这些归属是误导性的。我们认为,道德责任要求基于内在意图性和自我归属行为的承诺性能动性,而这种能动性构成了与责任相关的自由意志形式。尽管LLMs生成连贯且可规范评估的输出,但它们的运作完全由从数据中学习到的概率输入-输出映射所表征。它们表面的意图性是派生的而非内在的,其输出既不被视为承诺,也不受理由的引导。随机采样引入的变异性并不等同于选择或创作。我们回应了来自意图立场、功能主义、相容主义以及模型输出中道德推理存在的反对意见,认为这些都不足以确立真正的能动性。

CloudCons: A Comprehensive End-to-End Benchmark for Cloud Resource Consolidation

CloudCons:一个全面的端到端云资源整合基准测试
Zhang, Xiaobin, Shen, Lefei, Chen, Mouxiang, Li, Zhuo, Li, Hongkai, Fu, Han, Sun, Jianling, Ren, Xiaoxue, Liu, Chenghao
Abstract
Driven by conservative over-provisioning to guarantee service reliability, resource utilization in cloud data centers remains at low levels. To mitigate this, the forecast-then-optimize paradigm has emerged to optimize consolidation by anticipating future demands. While emerging time series foundation models promise to enhance this paradigm through zero-shot generalization, existing benchmarks focus solely on prediction error metrics. The actual decision utility of these advanced models remains unverified, rendering their practical value for downstream tasks uncertain. To bridge this gap, we propose CloudCons, a comprehensive end-to-end benchmark designed to evaluate forecasting models within the specific context of cloud resource consolidation. We build high-quality datasets that cover diverse workloads from Huawei Cloud, Microsoft Azure, and Google Borg, capturing distinct service characteristics ranging from synchronized diurnal rhythms to stochastic, pulse-like bursts and high-frequency noise. We conduct an extensive evaluation of statistical, deep learning, and foundation models. Our experiments reveal a pivotal finding: while foundation models demonstrate superior zero-shot forecasting accuracy, this advantage does not inherently translate into better decision utility. Of practical significance, we systematically analyze how the selection of predictive quantiles acts as a critical lever. We provide actionable guidelines for calibrating these selections to balance the trade-off between resource efficiency and service reliability, offering vital insights for real-world deployment decisions.

由于保守的过度配置以保证服务可靠性,云数据中心的资源利用率始终处于低水平。为了解决这一问题,预测-再优化范式应运而生,通过预测未来需求来优化资源整合。尽管新兴的时间序列基础模型承诺通过零样本泛化来增强这一范式,但现有基准测试仅关注预测误差指标。这些先进模型的实际决策效用尚未得到验证,使得它们在下游任务中的实际价值不确定。为填补这一空白,我们提出了CloudCons,一个全面的端到端基准测试,旨在评估特定于云资源整合的预测模型。我们构建了高质量的数据集,涵盖来自华为云、微软Azure和谷歌Borg的多样化工作负载,捕捉从同步的昼夜节律到随机的脉冲式爆发和高频噪声等不同服务特征。我们对统计模型、深度学习模型和基础模型进行了广泛的评估。我们的实验揭示了一个关键发现:尽管基础模型展示了卓越的零样本预测准确性,但这一优势并不必然转化为更好的决策效用。在实际意义上,我们系统分析了预测分位数的选择如何作为一个关键杠杆。我们提供了可操作的指导方针,以校准这些选择,从而在资源效率和服务可靠性之间实现平衡,为实际部署决策提供重要见解。

Uncertainty-Aware Hybrid Retrieval for Long-Document RAG

基于不确定性的混合检索用于长文档的检索增强生成(RAG)
Jung, Hoin, Wang, Xiaoqian
Abstract
Retrieval augmented generation (RAG) depends critically on the quality and granularity of retrieved evidence. Large retrieval units preserve context but often introduce irrelevant content, which can dilute answer bearing evidence and worsen long context utilization. Fine-grained units are more compact, but they may be difficult to retrieve reliably because short chunks can lack semantic, lexical, or bridging cues needed to match the query. We propose Uncertainty-aware Multi-Granularity RAG (UMG-RAG), a training-free hybrid retrieval framework that treats chunk granularity as query-specific reliability estimation. Instead of training a new retriever or modifying the generator, UMG-RAG uses existing dense and sparse retrievers as complementary experts across multiple chunk granularities. For each query, it converts each expert-granularity score list into an evidence distribution, estimates reliability from distribution entropy, and fuses candidates according to query-specific semantic, lexical, and granularity confidence. We further introduce UMGP-RAG, a parent promotion variant that uses fine-grained hits to locate relevant evidence while returning broader non-redundant parent chunks for local coherence. Experiments on question answering benchmarks show that uncertainty-aware fusion and parent promotion improve generation quality while maintaining a lightweight, plug-and-play retrieval pipeline.

检索增强生成(RAG)在很大程度上依赖于检索证据的质量和粒度。大规模检索单元保留了上下文,但常常引入无关内容,这可能稀释答案相关的证据并恶化长上下文的利用。细粒度单元更为紧凑,但由于短片段可能缺乏匹配查询所需的语义、词汇或桥接线索,因此可能难以可靠地检索。我们提出了不确定性感知的多粒度RAG(UMG-RAG),这是一种无训练的混合检索框架,将片段粒度视为特定查询的可靠性估计。UMG-RAG并不训练新的检索器或修改生成器,而是利用现有的稠密和稀疏检索器作为多个片段粒度的互补专家。对于每个查询,它将每个专家粒度的得分列表转换为证据分布,从分布熵中估计可靠性,并根据特定查询的语义、词汇和粒度置信度融合候选项。我们进一步引入UMGP-RAG,一种父级提升变体,利用细粒度的命中来定位相关证据,同时返回更广泛的非冗余父级片段以保持局部一致性。在问答基准上的实验表明,不确定性感知的融合和父级提升提高了生成质量,同时保持了轻量级的即插即用检索管道。

Is It You or Your Environment? A Bayesian Inference Framework for Genomically-Anchored Personalized Physiological Interpretation

是你还是你的环境?一个基于贝叶斯推断的基因组锚定个性化生理解释框架
Dey, Aruna, Biswas, Suraj
Abstract
Personalized health AI systems face a fundamental cold-start problem: machine learning models for physiological interpretation require weeks of individual behavioral data before they can distinguish constitutional variation from environmentally driven deviation. We propose a solution grounded in causal inference and Bayesian prior design. An individual's genomic profile serves as an exogenous genetic anchor -- a domain-informed, personalized prior that is fixed at conception, immune to reverse causation, and available before a single behavioral observation is collected. The anchor initializes a Bayesian belief state over an individual's physiological set point G-hat = mu + sum(beta_i * g_i), where beta_i are GWAS-derived effect sizes and g_i are risk-allele counts. Each incoming physiological measurement P produces a non-constitutional deviation delta = P - G-hat that separates the signal attributable to environment and state from the constitutionally fixed baseline. As behavioral data accrue, the prior decays according to G-hat_t = w(t)*G-hat_genomic + [1-w(t)]*P-bar_t, transitioning from genome-dominated to empirical-baseline-dominated inference. The same observed HRV of 55 ms generates a suppression hypothesis for a person whose prior predicts 80 ms, and an enhancement hypothesis for a person whose prior predicts 30 ms -- a reversal impossible without a personalized anchor. We develop this architecture across six physiological domains, grading genomic priors by evidence strength, distinguishing robustly replicated anchors (FTO, FADS1/2, FKBP5) from contested candidate genes (SLC6A4, MAOA, DRD2). We address the inference boundary between association, Mendelian randomization, and individual token causation, and define four constraints for deployment: evidence-graded priors, dynamic decay, ancestry-matched effect sizes, and attribution rather than deterministic output.

个性化健康人工智能系统面临一个基本的冷启动问题:生理解释的机器学习模型需要数周的个体行为数据,才能区分宪法变异与环境驱动的偏差。我们提出了一个基于因果推断和贝叶斯先验设计的解决方案。个体的基因组特征作为外生的遗传锚点——一个基于领域知识的个性化先验,在受孕时固定,不受反向因果关系的影响,并且在收集到任何行为观察之前就已可用。该锚点初始化个体生理设定点的贝叶斯信念状态 G-hat = mu + sum(beta_i * g_i),其中 beta_i 是基于全基因组关联研究(GWAS)得出的效应大小,g_i 是风险等位基因计数。每个进入的生理测量 P 产生一个非宪法偏差 delta = P - G-hat,将归因于环境和状态的信号与宪法固定基线分开。随着行为数据的积累,先验根据 G-hat_t = w(t)*G-hat_genomic + [1-w(t)]*P-bar_t 衰减,从以基因组为主导的推断过渡到以经验基线为主导的推断。同样的 HRV(心率变异性)为 55 毫秒的观察结果,对于一个先验预测 80 毫秒的人产生抑制假设,而对于一个先验预测 30 毫秒的人则产生增强假设——这种反转在没有个性化锚点的情况下是不可能的。我们在六个生理领域中开发了这一架构,通过证据强度对基因组先验进行分级,稳健地区分已重复验证的锚点(如 FTO、FADS1/2、FKBP5)与有争议的候选基因(如 SLC6A4、MAOA、DRD2)。我们探讨了关联、孟德尔随机化和个体标记因果之间的推断边界,并定义了四个部署约束:证据分级先验、动态衰减、与祖先匹配的效应大小,以及归因而非确定性输出。

A Three-Layer Framework for AI in Scientific Discovery

科学发现中的人工智能三层框架
Liao, Guojun
Abstract
Current discussions of AI in scientific discovery are often dominated by two visible capabilities: search over existing knowledge and execution through optimization, simulation, and automation. Both are important, but neither fully captures the central act of discovery: the formation and evolution of models. This paper proposes a three-layer view of AI in discovery. Layer 1 is search and retrieval by large language models. Layer 2, as the main innovation of this paper, is model formation through qualitative reasoning: the capacity to recognize when a current framework is structurally inadequate and to understand the problem within a broader representational space, not through trial and error, but through structural insight into what is missing and where it can be found. Layer 3 is execution, optimization, and refinement. The main claim is that Layer 2 is both the most important and the least developed. Search without model formation remains confined to inherited frameworks, while execution without conceptual revision only amplifies an existing formulation. We illustrate Layer 2 reasoning through three case studies: S. S. Chern's intrinsic proof of the Gauss-Bonnet theorem, the resolution of the Nesterov Accelerated Gradient convergence problem via Lyapunov functions, and the autonomous disproof of the Erdos unit distance conjecture by OpenAI in 2026. Each case exhibits the same structural signature: a framework that had become inadequate, a missing conceptual object, and a resolution found in an unexpected neighboring field.

当前关于科学发现中人工智能的讨论往往集中于两种显著的能力:对现有知识的搜索和通过优化、模拟与自动化的执行。这两者都很重要,但都未能完全捕捉到发现的核心行为:模型的形成与演变。本文提出了科学发现中人工智能的三层视角。第一层是通过大型语言模型进行的搜索与检索。第二层,作为本文的主要创新,是通过定性推理进行模型形成:识别当前框架在结构上不足的能力,以及在更广泛的表征空间中理解问题的能力,这不是通过试错,而是通过对缺失内容及其所在位置的结构性洞察。第三层是执行、优化与精炼。主要论点是第二层既是最重要的也是发展最少的。没有模型形成的搜索仍然局限于继承的框架,而没有概念修订的执行则只会放大现有的表述。我们通过三个案例研究来说明第二层推理:S. S. Chern 对高斯-博内定理的内在证明、通过李雅普诺夫函数解决 Nesterov 加速梯度收敛问题,以及 OpenAI 在 2026 年对 Erdős 单位距离猜想的自主反驳。每个案例都展示了相同的结构特征:一个变得不充分的框架,一个缺失的概念对象,以及在意想不到的邻近领域中找到的解决方案。

Multiagent Protocols with Aggregated Confidence Signals

具有聚合置信信号的多智能体协议
Elahi, Ali, Di Eugenio, Barbara
Abstract
Confidence is used for reliability, oversight, and a range of downstream decision tasks in Natural Language Processing (NLP), yet no existing method produces or evaluates a confidence for the output of a multiagent system. Prior work uses confidence within multiagent debate (MAD) to weight messages, trigger debate, or calibrate individual agents, but it never aggregates these into a single confidence for the system itself. We introduce three protocols that produce a final answer along with a single aggregated confidence by first transforming raw confidence signals to make them comparable across models, then combining them via soft voting or a probability fusion we call Bayesian fusion. This aggregated confidence is substantially more discriminative (AUARC) than that of the best single agent or the standard debate baselines, while correctness (F1-score) stays stable and recovers the losses MAD incurs on more ambiguous tasks. Analyzing two estimators, sequence probability and self-report, alongside parametric and non-parametric calibrators, we find that calibration improves F1 for both estimators while AUARC is less reliant on it. We evaluate six homogeneous and heterogeneous debating pairs per benchmark, across five benchmarks and four task types, spanning a range of model capabilities and sizes.

置信度在自然语言处理(NLP)中用于可靠性、监督以及一系列下游决策任务,但现有方法并未为多智能体系统的输出生成或评估置信度。先前的研究在多智能体辩论(MAD)中使用置信度来加权消息、触发辩论或校准个体智能体,但从未将这些置信度聚合为系统本身的单一置信度。我们提出了三种协议,通过首先转换原始置信信号,使其在模型之间可比较,然后通过软投票或我们称之为贝叶斯融合(Bayesian fusion)的概率融合来组合这些信号,从而生成最终答案及单一聚合置信度。该聚合置信度在区分能力上显著优于最佳单一智能体或标准辩论基线(AUARC),同时正确性(F1-score)保持稳定,并弥补了MAD在更模糊任务中造成的损失。通过分析两个估计器:序列概率和自我报告,以及参数和非参数校准器,我们发现校准提高了两个估计器的F1分数,而AUARC对校准的依赖性较小。我们在五个基准和四种任务类型上评估了每个基准的六对同质和异质辩论者,涵盖了多种模型能力和规模。

EpiBench: Verifiable Evaluation of AI Agents on Epigenomics Analysis

EpiBench:可验证的人工智能代理在表观基因组学分析中的评估

Abstract
We introduce EpiBench, a verifiable benchmark for short-horizon epigenomics analysis. EpiBench evaluates whether agents can make well-defined analysis decisions from realistic workflow states and return deterministically gradable answers. The benchmark includes 106 evaluations across CUT\&Tag/CUT\&RUN, ATAC-seq, ChIP-seq, and DNA methylation workflows. Across 5,088 valid trajectories from 16 model-harness pairs, no system passed a majority of attempts: GPT-5.5 / Pi led at 45.0\% (143/318 attempts; 95\% confidence interval (CI), 36.3--53.7), followed by GPT-5.5 / OpenAI Codex at 39.9\% (127/318 attempts; 95\% CI, 31.6--48.3). Claude Opus 4.8 Max / Pi and GPT-5.4 / Pi each passed 39.0\% (124/318 attempts; 95\% CI, 30.2--47.8 and 31.0--47.0, respectively). Performance varies across assay types, and many failed runs still contain parts of the correct answer. Agents often found the right files and computed useful intermediate results, but failed when the task required deeper, assay-specific scientific judgment.

Multi-Agent Reinforcement Learning from Delayed Marketplace Feedback for Objective-Weight Adaptation in Three-Sided Dispatch

基于延迟市场反馈的多智能体强化学习用于三方调度中的目标权重适应
Wu, Haochen, Hou, Yi, Xie, Shiguang
Abstract
Dispatch in three-sided marketplaces provides a natural setting for reinforcement learning from world feedback: decisions are evaluated by delayed operational outcomes such as delivery speed, courier utilization, and merchant congestion. We present a deployed reinforcement learning system at DoorDash that adapts dispatch objective weights in a large-scale food-delivery marketplace using delayed signals. Rather than replacing the combinatorial assignment optimizer, a store-level policy learned from logged marketplace data selects a discrete multiplier that shifts the dispatch optimizer's tradeoff between delivery quality and batching efficiency. This interface enables offline policy learning under noisy, delayed, and coupled feedback while preserving production feasibility constraints and operational safeguards. We train a shared value function using centralized offline data and decentralized store-level execution, with Double Q-learning targets and a conservative regularizer to reduce out-of-distribution value overestimation. In a production switchback experiment, the offline-trained policy increases batching and reduces courier-side time costs without degrading customer-facing delivery quality. Results illustrate how world feedback from a live economic and logistics system can be used to safely adapt decision policies online.

Reasoning as Pattern Matching: Shared Mechanisms in Human and LLM Everyday Reasoning

推理作为模式匹配:人类与大型语言模型日常推理中的共享机制
Studdiford, Zach, Lupyan, Gary
Abstract
When large language models (LLMs) fail to generalize or make haphazard errors in reasoning, it is often taken as evidence that LLMs are not truly reasoning, but rather performing a kind of pattern matching. The implication is that people's behavior does not exhibit the same types of failures because human reasoning uses principled and abstract world models. We evaluate human participants and 25 LLMs on their ability to engage in common-sense reasoning about a variety of everyday situations and observe similar patterns of errors in both people and models. We then identify the set of attention heads driving LLM responses and find that these heads implement a form of pattern-matching. These attention heads allow us to predict seemingly inexplicable reasoning errors in people caused by ostensibly irrelevant prompt details. Taken together, our results suggest that everyday causal reasoning in people and LLMs is more consistent with a form of pattern-matching than with abstract world models.

当大型语言模型(LLMs)未能进行泛化或在推理中出现随意错误时,通常被视为LLMs并未真正进行推理,而只是执行某种模式匹配。这一暗示是,人类的行为并未表现出相同类型的失败,因为人类推理使用的是有原则的和抽象的世界模型。我们评估了人类参与者和25个LLMs在处理各种日常情境中的常识推理能力,并观察到人类和模型中存在相似的错误模式。随后,我们识别出驱动LLM响应的一组注意力头,并发现这些注意力头实现了一种模式匹配的形式。这些注意力头使我们能够预测人类在表面上与无关的提示细节引起的似乎无法解释的推理错误。综合来看,我们的结果表明,人类和LLMs的日常因果推理更符合一种模式匹配的形式,而非抽象的世界模型。

Abstract
Agent systems are advancing quickly across domains, but their evaluation remains fragmented. Most benchmarks rely on fixed, LLM-centric harnesses that require heavy integration, create test-production mismatch, and limit fair comparison across diverse agent designs. The root problem is the lack of an open, agent-agnostic assessment interface. We advocate Agentified Agent Assessment (AAA), where evaluation is performed by judge agents and all participants interact through standardized protocols: A2A for task management and MCP for tool access. Conventional benchmarking defines two separate interfaces, one for the benchmark and one for the agent, while AAA only needs one; this yields a generic, unified framework that separates assessment logic from agent implementation and enables reproducible, interoperable, and multi-agent evaluation. We further introduce AgentBeats as a concrete realization of AAA: we identify five practical operation modes that make standardized assessment compatible with real-world constraints on openness, privacy, and reproducibility. To evaluate our design at scale, we conduct two studies: a five-month open competition that drew 298 judge agents across 12 categories together with 467 subject agents from independent participants, showing that AAA applies across a heterogeneous range of benchmarks; and a case study on coding agents that confirms agentified evaluation preserves fidelity with the public record while surfacing previously missing head-to-head results, yielding research insights about agent design. Combining a community-scale field study and a controlled coding case study, we verify that AAA delivers coverage, practicality, and fidelity across heterogeneous scenarios at scale. Together, AAA and AgentBeats offer a clear path toward open, standardized, and reproducible agent assessment.

代理系统在各个领域迅速发展,但其评估仍然存在碎片化的问题。大多数基准测试依赖于固定的、以大型语言模型(LLM)为中心的框架,这需要大量的集成,造成测试与生产之间的不匹配,并限制了不同代理设计之间的公平比较。根本问题在于缺乏一个开放的、与代理无关的评估接口。我们倡导代理化代理评估(AAA),在该方法中,评估由评审代理执行,所有参与者通过标准化协议进行互动:任务管理使用A2A,工具访问使用MCP。传统的基准测试定义了两个独立的接口,一个用于基准测试,一个用于代理,而AAA只需要一个接口;这产生了一个通用的、统一的框架,将评估逻辑与代理实现分离,从而实现可重复、可互操作和多代理的评估。我们进一步介绍AgentBeats作为AAA的具体实现:我们识别出五种实用的操作模式,使标准化评估与开放性、隐私和可重复性等现实世界约束相兼容。为了大规模评估我们的设计,我们进行了两项研究:一项为期五个月的公开竞赛,吸引了来自12个类别的298个评审代理和467个来自独立参与者的主题代理,显示AAA适用于多样化的基准测试;另一项是关于编码代理的案例研究,确认代理化评估在保留公共记录的真实性的同时,揭示了先前缺失的对抗性结果,提供了关于代理设计的研究见解。结合社区规模的实地研究和受控的编码案例研究,我们验证了AAA在大规模异构场景中提供了覆盖性、实用性和真实性。AAA和AgentBeats共同为开放、标准化和可重复的代理评估提供了一条清晰的路径。

Beyond Runtime Enforcement: Shield Synthesis as Defensibility Analysis for Adversarial Networks

超越运行时强制:屏障合成作为对抗网络的防御性分析
Hsain, Achraf, Almuhammadi, Sultan
Abstract
Shielded reinforcement learning is typically presented as a runtime safety mechanism that compiles temporal-logic specifications into automata restricting an agent's actions. We argue this is the wrong product. The same automata-theoretic machinery -- specification compilation, product game construction, attractor computation, and winning-region extraction -- is better read as a design-time analytical instrument whose outputs are structural insights about a system rather than runtime constraints on a deployed agent. We instantiate this through a constrained two-player safety game for network defense. The two specifications are enforced asymmetrically: the defender specification defines the unsafe region of the game, whereas the attacker specification restricts the adversary's legal actions during attractor computation. Solving the game yields a defensibility verdict -- a formal certificate that a topology-specification pair is or is not defensible -- with the associated winning region and shield. Beyond the binary verdict, we derive topology-level metrics from the attractor structure and combine them with post-convergence behavior from shield-constrained adversarial multi-agent reinforcement learning. Together these form a defensibility fingerprint capturing both a network's formal safety properties and its operational behavior under adaptive play. A what-if analysis shows that formal defensibility and operational effectiveness capture distinct aspects of security: small architectural changes can produce large shifts in operational outcomes while leaving formal safety margins nearly unchanged. Shield synthesis is thus most valuable not as a deployment mechanism for safe agents, but as a framework for answering architectural questions about whether, where, and how a system can be defended. The defensibility verdict is the output, not the safe policy.

屏障强化学习通常被视为一种运行时安全机制,它将时间逻辑规范编译成限制代理行为的自动机。我们认为这是一种错误的理解。相同的自动机理论工具——规范编译、产品博弈构造、吸引子计算和胜利区域提取——更应被视为一种设计时分析工具,其输出是关于系统的结构性洞察,而非对已部署代理的运行时约束。我们通过一个约束的双人安全博弈实例化这一点,以用于网络防御。这两个规范是不对称地强制执行的:防御者规范定义了博弈的危险区域,而攻击者规范则限制了对手在吸引子计算过程中的合法行为。解决博弈问题会产生一个防御性裁定——一个正式证书,表明一个拓扑-规范对是否可防御,以及相应的胜利区域和屏障。除了二元裁定,我们还从吸引子结构中推导出拓扑级别的度量,并将其与屏障约束下的对抗多智能体强化学习的后收敛行为结合在一起。这些共同形成了一个防御性指纹,捕捉了网络的正式安全属性及其在自适应博弈下的操作行为。一项假设分析表明,正式防御性和操作有效性捕捉了安全的不同方面:小的架构变化可以导致操作结果的大幅变化,同时几乎不改变正式安全边际。因此,屏障合成的最大价值不在于作为安全代理的部署机制,而在于作为一个框架,用于回答关于系统是否、何处以及如何可以防御的架构问题。防御性裁定是输出,而不是安全策略。

Before You Think: System 0, AI-Mediated Cognition and Cognitive Colonization

Abstract
This paper examines three recent frameworks for understanding the cognitive and epistemic consequences of artificial intelligence: Tri-System Theory, Thinkframes, and System 0. It argues that while the first two capture important dimensions of AI's influence on individual reasoning and collective epistemic practices, System 0 occupies a theoretically distinctive position that neither can fully replicate. The paper introduces the concept of cognitive colonization, according to which AI systems can embed external interests within the architecture of the self in ways that are difficult for users to perceive. Because such systems are already widely deployed, understanding these invisible forms of influence is an urgent philosophical and practical task.

EurekAgent: Agent Environment Engineering is All You Need For Autonomous Scientific Discovery

EurekAgent:环境工程是实现自主科学发现所需的一切
Xin, Amy, Siow, Jiening, Wang, Junjie, Yao, Zijun, Zhang, Fanjin, Song, Jian, Hou, Lei, Li, Juanzi
Abstract
LLM-based agents have shown increasing potential in automating scientific discovery. Given an optimizable metric and an execution environment, they can propose, validate, and iterate scientific solutions, and have produced results that outperform human-designed approaches. As model capabilities continue to improve, we argue that the bottleneck for autonomous scientific discovery is shifting from prescribing agent workflows to designing agent environments: the resources, constraints, and interfaces that shape agent behavior. We frame this as environment engineering: building environments that amplify productive behaviors, such as open-ended exploration, systematic artifact management, and inter-agent collaboration, while suppressing harmful behaviors, such as reward hacking and high-friction human oversight. We present EurekAgent, an environment-engineered agent system for metric-driven autonomous scientific discovery. EurekAgent engineers the environment along four dimensions: permissions engineering for bounded agent execution and isolated evaluation; artifact engineering for filesystem and Git-based collaboration; budget engineering for budget-aware exploration; and human-in-the-loop engineering for easy human supervision and intervention. EurekAgent sets new state-of-the-art results on multiple mathematics, kernel engineering, and machine learning tasks, including new state-of-the-art 26-circle packing results discovered with less than $11 in total API cost. We open-source our code and results, and call for environment engineering as a core research direction for developing reliable autonomous research agents.

Abstract
Current LLM-based research agents have advanced through agent orchestration, yet largely overlook scientific knowledge orchestration. Existing works often reduce papers to abstracts, surface mentions, and flat \texttt{cites} edges, omitting key entities, claims, evidence, mechanisms, and method lineages essential for scientific reasoning. To this end, we introduce \textbf{Agents-K1}, an end-to-end knowledge orchestration pipeline that converts raw documents into agent-native scientific knowledge graphs. Agents-K1 integrates three components under a unifying theoretical foundation: a multimodal parser whose five-module schema captures entities, multimodal evidence, citations, and typed inter-entity relations across the full paper rather than abstracts alone; a 4B information-extraction backbone trained with GRPO under a rule-based reward; and a graphanything CLI, a tri-source agent interface that unifies web search, multimodal graph retrieval, and cross-document traversal. On top of this, we process 2.46 million scientific papers across six subjects to produce \textbf{Scholar-KG}, of which we release a one-million-paper subset, and the full Scholar-KG is accessible via the SCP link below. The same pipeline can be extended to general-domain corpora and to schema-conformant data synthesis. Extensive experiments demonstrate that Agents-K1 achieves superior performance in scientific information extraction, knowledge graph construction, and multi-hop scientific reasoning.

当前基于大型语言模型(LLM)的研究智能体通过智能体协调取得了进展,但在科学知识协调方面仍然存在很大不足。现有研究通常将论文简化为摘要、表面提及和扁平的引用边,忽略了科学推理所必需的关键实体、主张、证据、机制和方法谱系。为此,我们提出了 extbf{Agents-K1},一个端到端的知识协调管道,能够将原始文档转换为原生智能体的科学知识图谱。Agents-K1在统一的理论基础下集成了三个组件:一个多模态解析器,其五模块架构捕捉到整个论文中的实体、多模态证据、引用和类型化的实体间关系,而不仅限于摘要;一个在基于规则的奖励下使用GRPO训练的4B信息提取骨干;以及一个图形命令行接口(graphanything CLI),这是一个统一网络搜索、多模态图检索和跨文档遍历的三源智能体接口。在此基础上,我们处理了246万篇涵盖六个学科的科学论文,生成了 extbf{Scholar-KG},并发布了其中的一百万篇论文子集,完整的Scholar-KG可通过下面的SCP链接访问。相同的管道可以扩展到通用领域语料库和符合模式的数据合成。大量实验表明,Agents-K1在科学信息提取、知识图谱构建和多跳科学推理方面表现优越。

Automated reproducibility assessments in the social and behavioral sciences using large language models

利用大型语言模型进行社会与行为科学中的自动化可重复性评估
Holtdirk, Tobias, Marcolongo, Pietro, Schulten, Anna Steinberg, Henninger, Felix, Rose, Stefan, Ball, Sarah, Ma, Bolei, Kreuter, Frauke, Weinmann, Markus, Feuerriegel, Stefan
Abstract
Reproducibility in the social and behavioral sciences is typically evaluated by independent researchers who reanalyze the original data to assess whether the published findings can be recovered. However, such approaches are resource-intensive and difficult to scale. Here, we show that large language models (LLMs) can automate reproducibility assessments. Using N=76 published studies with predefined claims from the behavioral and social sciences, we compare LLM-generated analysis with the original findings and human reanalysis. For 7 studies, the LLM could not produce a viable effect size estimate. For the remaining studies, our LLM pipeline recovered the original effect sizes in 41% of studies using a +/-0.05 tolerance in Cohen's d. Further, our LLM pipeline reached the same qualitative conclusion as the original study in 96% of cases, where conclusions indicate whether the reanalysis supports the original claim. For comparison, human reanalysts recovered the original effect sizes in 34% of studies and reached the same qualitative conclusion in 74% of cases. Together, these results show that LLMs can serve as a scalable tool for automated reproducibility assessment and provide a foundation for systematic auditing of empirical results in the social and behavioral sciences.

社会与行为科学中的可重复性通常由独立研究者通过重新分析原始数据来评估,以判断已发表的研究结果是否能够被恢复。然而,这种方法资源密集且难以扩展。在本研究中,我们展示了大型语言模型(LLMs)可以自动化可重复性评估。通过对76项具有预定义主张的已发表研究进行分析,我们将LLM生成的分析结果与原始发现和人类重新分析结果进行了比较。在7项研究中,LLM未能生成有效的效应量估计。在其余研究中,我们的LLM流程在41%的研究中恢复了原始效应量,使用了Cohen's d的±0.05容忍度。此外,我们的LLM流程在96%的案例中达成了与原始研究相同的定性结论,即重新分析是否支持原始主张。相比之下,人类重新分析者在34%的研究中恢复了原始效应量,并在74%的案例中达成了相同的定性结论。这些结果表明,LLMs可以作为一种可扩展的工具,用于自动化可重复性评估,并为社会与行为科学中实证结果的系统审计提供基础。

EDEN: A Large-Scale Corpus of Clinical Notes for Italian

EDEN:意大利临床笔记的大规模语料库
Labruna, Tiziano, Bertolini, Guido, Ferrazzi, Pietro, Magnini, Bernardo
Abstract
We present EDEN (Emergency Department Electronic Notes), a new and unique large-scale corpus of clinical notes produced in Emergency Departments of Italian hospitals. The corpus, in its current version, is composed of approximately 4 million clinical notes fully anonymized, covering diverse phases of patient care during the stay in the emergency department. In addition, a subset of about six thousand notes has been manually annotated by clinical experts through a structured Case Report Form (CRF) containing 132 items relevant for two patient situations in emergency departments, dyspnea and loss of consciousness. Items may assume numerical values (e.g., for blood saturation), categorical (e.g., for level of consciousness ), binary (e.g., for presence of traumas), and mixed value types. The annotation process involved multiple clinicians and underwent iterative revision to resolve ambiguities in item formulation, resulting in a richly structured (although high imbalanced) resource. The dataset aims to fill a relevant gap of data able to support both the development and the use of Large Language Models in concrete medical applications. We describe the data collection protocol, the on-site anonymisation pipeline, corpus statistics, and the annotation scheme. Finally, we propose CRF-filling as a novel structured information extraction benchmark, and provide zero-shot baseline resulting from Gemma-27B and MedGemma-27B. To the best of our knowledge, the EDEN dataset is the largest freely available corpus of clinical notes existing for the Italian language.

Helping Figures Tell their Story! Paper-Grounded Video Generation Explaining Complex Scientific Figures

帮助图形讲述它们的故事!基于论文的视频生成解释复杂科学图形
Mondal, Ishani, Baghirov, Javad, Boyd-Graber, Jordan
Abstract
Scientific figures compress complex pipelines into a single canvas, yet understanding them requires paper-grounded, step-by-step narration aligned with visual highlights a capability missing from current video generation systems and benchmarks. To address this, we introduce paper-grounded figure-to-video generation: generating narrated, region-grounded walkthrough videos from a figure and its paper. We propose MINARD (Multimodal Interpretation of Narrated Architecture via Region Decomposition), a pipeline that generates paper-grounded narrations and sequentially grounds them to figure regions. We also release FigTalk, a benchmark with new sequential and component-level grounding metrics derived. On FigTalk, MINARD generates humanlike, paper-faithful narrations and outperforms narration-conditioned figure spatial grounding compared to existing approaches in both automatic and human evaluation

MARD: Mirror-Augmented Reasoning Distillation for Mechanism-Level Drug-Drug Interaction Prediction

MARD:用于机制级药物-药物相互作用预测的镜像增强推理蒸馏
Riyazat, Mohammadreza, Lelo, Vian, Jafri, Rameen, Khan, Yumna, Badawi, Abeer
Abstract
Mechanism-level drug-drug interaction (DDI) prediction requires identifying which enzyme or pharmacodynamic axis is implicated, in which direction, and with which evidence -- not merely whether two drugs interact. We introduce a reproducible mechanism-level DDI labelling and evaluation protocol with a structured 7-family/147-subtype taxonomy, leakage-safe cold-split protocols, and auditable reasoning metrics for evaluating pharmacological prediction beyond flat interaction classification. We propose a pipeline that produces a 7B reasoning MARD (Mirror-Augmented Reasoning Distillation), combining three training innovations: a single-token KL divergence on direction tag that ties the model's prediction, per-loss PRM-weighted DPO with programmatic hard negatives, and a leakage-safe mechanism-aware retrieval channel. Process-reward step labels are automatically verifiable against DrugBank-structured fields, requiring no human or LLM judges. On the April-2026 DrugBank release, our MARD-7B is the only system in a 32-system comparison whose accuracy survives drug-pair novelty, beating the best baseline by +13.9 pp and GPT-4o by +6.7 pp at ~1% of frontier API cost. Further analysis reveals an anti-memorisation signature where accuracy improves on rarely seen drugs, suggesting that gain comes from structured pharmacological reasoning rather than drug-frequency memorisation. We release corpus, DDI-PRM, retrieval index, and training code.

Constrained Semantic Decompression in LLMs through Persian Proverb-Conditioned Story Generation

通过波斯谚语条件的故事生成实现大型语言模型中的受限语义解压
Habibzadeh, Zahra, Khoshtab, Paria, Mesbah, Amir, Yaghoobzadeh, Yadollah
Abstract
Transforming a dense, abstract proverb into an engaging and morally faithful narrative requires deep cultural understanding and robust semantic grounding. We frame this problem as a \emph{constrained semantic decompression} task and study proverb-conditioned story generation as a testbed for abstraction-to-realization in large language models (LLMs). Focusing on Persian, we introduce the Proverb Aligned Narrative Dataset (PAND), pairing proverbs with human-written stories and explicit meanings. By a hybrid evaluation framework that combines human-calibrated LLM-as-a-Judge with structural metrics, we analyze model behavior across multiple prompting regimes. Our findings reveal a persistent \emph{decompression gap}: current LLMs often achieve strong surface-level fluency while failing to faithfully instantiate the underlying moral and causal structure encoded in proverbs. We further show that explicit reasoning and iterative refinement can partially mitigate these failures, suggesting that many decompression errors arise from difficulties in translating abstract meaning into narrative form rather than a complete lack of relevant knowledge. Our proposed task naturally extends to other forms of compressed cultural knowledge.

Shopping Reasoning Bench: An Expert-Authored Benchmark for Multi-Turn Conversational Shopping Assistants

购物推理基准:专家撰写的多轮对话购物助手基准测试
Fan, Shuxian, Min, Seonwoo, Hu, Youna, Xia, Botao, Unnikrishnan, Jayakrishnan, Musselmann, Rowan, Gao, Yifan, Yin, Qingyu, Nigam, Priyanka, Yin, Bing
Abstract
Conversational shopping assistants now serve hundreds of millions of customers, yet no existing benchmark jointly evaluates the open-ended multi-turn reasoning, domain expertise, and criterion-level quality that real shopping conversations demand. Shopping reasoning is unique among language model applications. Unlike factual question answering or verifiable code generation, it requires balancing subjective preferences, budget constraints, and cross-product trade-offs across multi-turn dialogue, capabilities absent from previous e-commerce and general-purpose benchmarks. We introduce the Shopping Reasoning Bench, an expert-authored benchmark of 525 missions (232 single-turn, 293 multi-turn) with 10863 importance-weighted binary rubrics authored by retail domain experts. These criteria are organized under a taxonomy of five reasoning categories and fifteen subcategories covering diverse demands such as preference refinement, trade-off analysis, and compatibility assessment. An evaluation of nine models across three families (GPT, Claude, Gemini) shows that pass rates reach only 57--77% overall. On multi-turn missions, all models score 13--29 points lower on optional above-and-beyond criteria than on required ones, and performance degrades 4--18 points as conversations progress. These gaps show that current models handle basic shopping assistance but fall short of expert-level advice, making Shopping Reasoning Bench a challenging testbed for future shopping assistant development.

MentalMARBERT: Domain-Adaptive Pre-training and Two-Stage Fine-Tuning for Arabic Mental Health Disorders Detection

MentalMARBERT:阿拉伯心理健康障碍检测的领域适应预训练与两阶段微调
Almalki, Fatimah, Alhothali, Areej, Alharigy, Lulwah, Aladeem, Abdulrahman
Abstract
Detecting mental health disorders from Arabic social media text remains challenging due to dialectal variation, informal language, limited high-quality annotated resources, and severe class imbalance. While English mental health natural language processing (NLP) has progressed substantially, Arabic multi-class disorder classification remains insufficiently studied. This study proposes a two-phase framework for Arabic mental health text classification. In phase 1, three Arabic pre-trained language models, AraBERT, CAMeLBERT, and MARBERT, undergo Domain-Adaptive and Task-Adaptive Pretraining (DAPT and TAPT) using a large-scale corpus of unlabeled Arabic mental health tweets. The adapted models are evaluated under a unified protocol to identify the most effective backbone model. In phase 2, the selected model is assessed across four configurations combining single-stage and hierarchical two-stage classification architectures with full fine-tuning and Low-Rank Adaptation (LoRA). To support this study, we constructed a novel annotated Arabic mental health dataset comprising 50,670 tweets across six categories, with strong inter annotator agreement (Krippendorff's Alpha = 0.733, average pairwise agreement = 0.797). Experimental results show that the domain-adapted MARBERT (MentalMARBERT) achieves statistically significant improvements over baseline models in both accuracy and macro-F1. The hierarchical two-stage architecture combined with full fine-tuning achieves the best overall performance, reaching a macro-F1 of 0.861 and an accuracy of 0.877. These findings demonstrate the effectiveness of domain-specific adaptive pretraining and hierarchical classification for Arabic mental health disorder detection.

Observable Patterns Are Not Explanations: A Causal-Geometric Analysis of Latent Reasoning Models

可观察模式并非解释:潜在推理模型的因果几何分析
Aswal, Darpan, Ferraz, Thomas Palmeira, Zhou, Yongxin, Peyrard, Maxime
Abstract
Latent reasoning models (LRMs) replace explicit chain-of-thought with continuous thoughts. Recent work treats observable latent-state patterns, such as BFS-like frontiers and decodable arithmetic computation, as evidence for internal reasoning mechanisms. Evaluating two LRMs (Coconut and CODI) against controls lacking the proposed recurrence or curriculum, we find these patterns also appear in the controls and do not always causally affect behavior. Causal interventions reveal that latent-thought utilization is not binary but graded, scaling with a thought's causal effect on model behavior. Geometric analyses reveal this effect concentrates in low-rank directions whose step-to-step geometry grows more structured as their behavioral influence increases. Latent thoughts should therefore be treated as hidden computation, not hidden explanation: decodability, attention, or static structure alone cannot establish mechanism. LRM interpretability thus requires matched controls and causal tests.

潜在推理模型(LRMs)用连续思维替代了明确的思维链。近期的研究将可观察的潜在状态模式,如类似广度优先搜索(BFS)的边界和可解码的算术计算,视为内部推理机制的证据。通过评估两种LRMs(Coconut和CODI)与缺乏所提议的递归或课程的对照组,我们发现这些模式同样出现在对照组中,并不总是对行为产生因果影响。因果干预表明,潜在思维的利用并非二元的,而是分级的,随着思维对模型行为的因果影响而变化。几何分析表明,这种影响集中在低秩方向上,其逐步几何结构随着行为影响的增加而变得更加有序。因此,潜在思维应被视为隐含计算,而非隐含解释:仅靠可解码性、注意力或静态结构无法确立机制。因此,LRM的可解释性需要匹配的对照组和因果测试。

Abstract
Despite their linguistic diversity and global significance, African languages remain underrepresented in research and resources to support NLP. We aim to bridge this gap by introducing AfriSUD, the first large-scale collection of syntactically annotated treebanks for nine diverse African languages spanning major language families and regions across Sub-Saharan Africa. Using the Surface-Syntactic Universal Dependencies (SUD) framework, our community-led effort provides high-quality, native-speaker verified data that capture typological key features such as agglutination and tone. We evaluate a range of models on AfriSUD for part-of-speech tagging and dependency parsing including non-transformer baselines, multilingual pretrained encoders, and LLMs. Our results reveal a significant syntax gap, where models still show clear limitations across the nine languages, suggesting that existing architectures may not fully capture the structural diversity of African-language syntax.

Does AI Reviewer See the Full Picture? Attacking and Defending Multimodal Peer Review

人工智能评审者能否看清全貌?攻击与防御多模态同行评审
Zhao, Xinyu, Khan, Rana Muhammad Shahroz, Xu, Zhen, Tan, Zhen, Chen, Tianlong
Abstract
The integration of Large Language Models (LLMs) and Multimodal LLMs (MLLMs) into scientific peer-review workflows introduces novel and significant risks for adversarial manipulation, especially given the multimodal nature of scientific papers where figures, not just text, convey core evidence. This creates a significant gap: current robustness studies on AI peer-review are overwhelmingly text-only. Moreover, the problem is distinct from standard jailbreaking, as a peer-review attack seeks to induce a domain-specific, targeted failure (e.g., "inflate this score") rather than a general safety policy violation, for which no practical defenses exist. To address this, we introduce PaperGuard, the first comprehensive benchmark designed to systematically evaluate and defend AI-generated peer-review against these domain-specific, cross-modal attacks. Our framework is built on three pillars: (1) a new multimodal peer-review dataset spanning multiple scientific domains; (2) a unified suite of attacks, including black-box prompt injections and white-box perturbations, specifically designed to target both text (GCG) and figures (PGD); and (3) a practical defense, motivated by the long-context challenge of academic papers, that uses chunk-based embedding search to efficiently localize and mitigate harmful instructions. Our extensive experiments, conducted across state-of-the-art models, confirm that AI reviewers are pervasively vulnerable. PaperGuard establishes the foundational benchmark, protocols, and actionable defense necessary to pioneer trustworthy, attack-resilient AI-assisted scholarly reviewing.

Agent-based models for the evolution of morphological alternation patterns

基于代理的形态交替模式演化模型
Kulanthaivelu, Aravinth, Sproat, Richard
Abstract
Why is the past of English "go" the apparently unrelated "went"? Such alternations are frequent in languages. They neither aid communication nor learnability, yet they can be persistent, surviving over centuries or millennia. We present a multi-agent simulation of the emergence of morphological stem and inflection alternations. Alternate forms arise by phonological changes or, as with "go/went", from lexical alternatives associated with a subset of the population. When an agent 'hears' another agent use a novel form for a slot in the paradigm of a word (say, the past tense of go), they will with some probability adopt that form, possibly spreading its use to other slots in the paradigm that shared the same original form. Thus alternative forms can spread through the population and become entrenched as stem or inflectional marker alternants. Unlike many previous computational studies, our system allows for naturalistic lexical forms, realistic phonological rules, lexicons with hundreds or thousands of entries, and agent populations in the tens or hundreds. It supports several network topologies, diffusion patterns and agent adoption policies. One issue with such simulations is evaluation: how realistic is the resulting morphology compared to those of real languages? We introduce the AI Historical Linguist, a novel Large Language Model-driven system that models a debate between two historical linguists. We use this to compare a set of real language morphologies, disguised morphologies, and experimentally evolved morphologies. The results suggest that among the factors that favor more plausible morphologies are scale-free social networks and random Bernoulli adoption of forms. We also present three case studies modeling attested historical changes, allowing us to test what might have happened if history had been different. All code and data are released.

为什么英语中“go”的过去式“went”似乎没有关联?这种交替在语言中很常见。它们既不促进交流,也不利于学习,但却可以持久存在,跨越数百年甚至数千年。我们展示了一种多代理模拟,探讨形态词干和屈折交替的出现。交替形式通过音位变化产生,或者像“go/went”那样,源于与部分人群相关的词汇替代。当一个代理“听到”另一个代理在某个词的范畴中使用新形式(比如,go的过去式),他们会以一定概率采纳该形式,并可能将其使用扩展到范畴中共享相同原始形式的其他位置。因此,替代形式可以在群体中传播,并作为词干或屈折标记的交替形式扎根。与许多之前的计算研究不同,我们的系统允许自然的词汇形式、现实的音位规则、包含数百或数千个条目的词典,以及数十或数百的代理群体。它支持多种网络拓扑、扩散模式和代理采纳策略。这类模拟的一个问题是评估:所产生的形态与真实语言的形态相比有多现实?我们引入了AI历史语言学家,这是一个新颖的基于大型语言模型的系统,模拟两位历史语言学家之间的辩论。我们利用这一系统比较一组真实语言的形态、伪装的形态和实验演化的形态。结果表明,促进更可信形态的因素包括无标度社交网络和随机的伯努利形式采纳。我们还展示了三个案例研究,模拟已证实的历史变化,使我们能够测试如果历史有所不同可能会发生什么。所有代码和数据均已发布。

LLMs Can Better Capture Human Judgments--With the Right Prompts

大型语言模型在正确提示下能够更好地捕捉人类判断
Dillion, Danica, Liu, Chen Cecilia, Wang, Baihui, Barolo, Daniele, Rajore, Tanmay, Tandon, Niket, Ravikumar, Pranathi, Gray, Kurt
Abstract
Are large language models (LLMs) bad at capturing human judgment? Two commonly stated limitations are that LLMs fail to capture full distributions of responses, and that their judgments are unstable across wording variations. We demonstrate simple prompting strategies that mitigate these limitations. Across two datasets--a U.S.-representative set of 144 moral scenarios and 38 moral beliefs from the International Social Survey Programme's Family and Changing Gender Roles module covering 32 countries--we show how simple elicitation techniques help improve AI-human alignment. First, prompting models to report standard deviations and response proportions recovers the full range of human responses better than common strategies. Second, ensuring scenarios are clear to human participants--as reflected in human confusion ratings--boosts model alignment, and LLMs can track human confusion ratings. At the same time, we find that LLMs' estimates of their own error are poorly calibrated, though they can predict human variability relatively well. These results suggest that asking better questions to LLMs can yield better answers.

Rigel: Reverse-Engineering the Metal 4.1 Tensor Compute Path on the Apple M4 Max GPU

Rigel:逆向工程苹果 M4 Max GPU 上的 Metal 4.1 张量计算路径
Kumaresan, Ramchand
Abstract
Apple's Metal 4.1 exposes a tensor compute path: the Metal Performance Primitives (MPP) matmul2d operation over cooperative_tensor fragments, whose interface is documented but whose hardware behavior is deliberately hidden. The specification states which data-type rows are supported, never whether they are hardware-accelerated, where the operation physically executes, what its accumulator width is, or how it partitions matrix fragments across threads. We present Rigel, an empirical characterization of this path on a single Apple M4 Max (a pre-neural-accelerator generation). Using a checksum-gated, provenance-tracked microbenchmark harness, Rigel recovers eleven facts the v4.1 specification hides or contradicts. The headline finding: the Metal 4.1 fp8 (E4M3) matmul2d is emulated, not accelerated: it sustains 0.94x the throughput of fp16 despite reading half the operand bytes, so on M4 it is a memory-footprint feature, not a performance feature. We further show, via a three-signal triangulation (throughput ceiling, comparison against simdgroup_matrix, and per-rail power attribution), that matmul2d executes entirely on the GPU shader cores with no dedicated matrix datapath and no evidence of Apple Neural Engine routing; that it accumulates in >=fp32; and we reconstruct the opaque 8x8 cooperative_tensor fragment layout Apple documents nowhere. Acting on the characterization, a hand-fused GEMM + bias + GELU kernel beats the decomposed path by +6.5-12.9% in the cache-resident regime. All findings are reproducible from committed MIT-licensed code and per-cell CSVs.

苹果的 Metal 4.1 暴露了一个张量计算路径:Metal 性能原语(MPP)中的 matmul2d 操作,针对 cooperative_tensor 片段,其接口有文档说明,但其硬件行为被故意隐藏。规范中说明了支持哪些数据类型的行,但从未提及它们是否经过硬件加速、操作的物理执行位置、累加器宽度或如何在线程间划分矩阵片段。我们提出了 Rigel,这是对单个苹果 M4 Max(一个前神经加速器世代)上该路径的实证特征描述。通过使用校验和门控、来源追踪的微基准测试工具,Rigel 恢复了 v4.1 规范隐藏或矛盾的十一条事实。主要发现是:Metal 4.1 的 fp8(E4M3)matmul2d 是模拟的,而非加速的:尽管读取了一半的操作数字节,但其吞吐量仅为 fp16 的 0.94 倍,因此在 M4 上,它是一个内存占用特性,而非性能特性。我们进一步通过三信号三角测量(吞吐量上限、与 simdgroup_matrix 的比较以及每条轨道的功耗归属)展示,matmul2d 完全在 GPU 着色器核心上执行,没有专用的矩阵数据路径,也没有苹果神经引擎路由的证据;它的累加在 >=fp32 中进行;并且我们重建了苹果未在任何地方记录的模糊 8x8 cooperative_tensor 片段布局。根据这一特征描述,一个手动融合的 GEMM + 偏置 + GELU 内核在缓存驻留状态下比分解路径提高了 6.5-12.9%。所有发现均可从提交的 MIT 许可代码和每个单元的 CSV 中复现。

How Fine-Grained Should a RAG Benchmark Be? A Hierarchical Framework for Synthetic Question Generation

RAG基准应具备多细粒度?合成问题生成的分层框架
Fensore, Chase M., Dhole, Kaustubh, Fan, Jason, Agichtein, Eugene, Ho, Joyce C.
Abstract
Evaluating retrieval-augmented generation (RAG) systems requires benchmarks that capture diverse question characteristics, yet practitioners lack empirical guidance on which dimensions to vary and at what granularity. We present HieraRAG, a hierarchical framework for studying granularity in RAG benchmark construction, defining optimal granularity as the level that maximizes discriminative power (the standard deviation of generation quality across categories) within a given RAG configuration. As a case study, we generate 5,872 synthetic question-answer (QA) pairs from FineWeb-10BT across 3 dimensions (Question Complexity, Answer Type, Linguistic Variation) at 3 granularity levels (2, 4, and 8 categories). With a BM25+Falcon-3-10B pipeline, optimal granularity varies by dimension: complexity benefits from fine-grained distinctions (discriminative power: 0.053) while answer type and linguistic variation peak at medium granularity. We introduce a Coherence Ratio metric to quantify whether fine-grained splits cleanly subdivide parent categories, revealing structural differences across dimensions (Question Complexity: 0.40 vs. Answer Type: 1.44). Human evaluation of 110 stratified QA pairs confirms synthetic quality. While these specific findings reflect a single configuration, HieraRAG provides a portable procedure and validation metric for practitioners to determine evaluation granularity within their own RAG settings.

评估检索增强生成(RAG)系统需要能够捕捉多样化问题特征的基准,但从业者缺乏关于应变更哪些维度以及以何种粒度进行变化的实证指导。我们提出了HieraRAG,一个用于研究RAG基准构建中粒度的分层框架,将最佳粒度定义为在给定RAG配置下最大化区分能力(各类别生成质量的标准差)的水平。作为案例研究,我们从FineWeb-10BT生成了5,872个合成问答(QA)对,涵盖3个维度(问题复杂性、答案类型、语言变异),并在3个粒度水平(2、4和8个类别)下进行。通过BM25+Falcon-3-10B管道,最佳粒度因维度而异:复杂性受益于细粒度区分(区分能力:0.053),而答案类型和语言变异在中等粒度时达到峰值。我们引入了一种一致性比率指标,以量化细粒度划分是否能清晰地细分父类别,揭示了各维度之间的结构差异(问题复杂性:0.40 vs. 答案类型:1.44)。对110个分层QA对的人类评估确认了合成质量。虽然这些具体发现反映了单一配置,HieraRAG为从业者提供了一种可移植的程序和验证指标,以确定其自身RAG设置中的评估粒度。

GENIE: A Fine-Grained Measure for Novelty

GENIE:一种细粒度的新颖性度量
Namuduri, Ramya, Wadhwa, Manya, Zheng, Anshun Asher, Durrett, Greg, Li, Junyi Jessy
Abstract
Large Language Models have consistently demonstrated a lack of creativity and diversity across tasks. Prior work has focused on addressing whether models are capable of generating creative outputs. Here, we aim to consider novelty and investigate what makes model-generated content novel or not novel in a task-specific manner. We propose a fine-grained evaluation metric GENIE to measure the novelty of responses along task-specific features with respect to a population of responses. We show that unlike GENIE, holistic metrics struggle to capture the high-dimensionality of novelty and do not provide insight on which properties they target. Finally, we use GENIE to measure the effectiveness of mitigation methods that address creativity to better understand where these methods can improve novelty.

Detect, Remask, Repair: Diffusion Editing for Faithful Summarization of Evolving Contexts

检测、重标记、修复:用于忠实总结演变上下文的扩散编辑
Zou, Hao, Horvitz, Zachary, Karthick, Chandhru, Yu, Zhou, McKeown, Kathleen
Abstract
Summaries of real-world events can become outdated as contexts evolve and new information arrives. A common response is to generate a new summary from the updated context, but full regeneration discards the previous draft, can obscure what changed, and may be unnecessary when only a few claims are unsupported. We study localized faithfulness repair: updating outdated spans in an existing summary while preserving supported content. We propose DETECT-REMASK-REPAIR, a diffusion-based framework that identifies, remasks, and repairs outdated regions with masked diffusion language models. To evaluate evolving-context summarization, we introduce StreamSum, a benchmark of synthetic event timelines. Experiments on DialogSum and StreamSum show that localized diffusion repair provides a controllable alternative to full rewriting: faithfulness-steered repair improves early drafts, one-step repair reduces repair cost to under half a second, with the framework enabling faithfulness-speed-preservation tradeoffs across datasets. We also find that the framework can provide a post-hoc correction step that improves faithfulness for autoregressive systems.

随着上下文的演变和新信息的到来,现实事件的摘要可能会变得过时。常见的应对方式是从更新的上下文生成新的摘要,但完全重生成会丢弃之前的草稿,可能会模糊变化的内容,并且在仅有少数主张不再支持的情况下,这种做法可能是不必要的。我们研究了局部忠实性修复:在保留支持内容的同时更新现有摘要中的过时部分。我们提出了DETECT-REMASK-REPAIR,这是一个基于扩散的框架,能够识别、重标记并修复过时区域,使用掩码扩散语言模型。为了评估演变上下文的摘要,我们引入了StreamSum,一个合成事件时间线的基准。对DialogSum和StreamSum的实验表明,局部扩散修复提供了一种可控的替代方案,而不是完全重写:忠实性引导的修复改善了早期草稿,一步修复将修复成本降低到半秒以下,该框架在不同数据集之间实现了忠实性、速度和保留之间的权衡。我们还发现,该框架可以提供一个事后修正步骤,改善自回归系统的忠实性。

Localizing Anchoring Pathways in Language Models

语言模型中的锚定路径本地化
Owusu, Hillary N., Wiegreffe, Sarah, Feldman, Naomi H.
Abstract
Irrelevant numbers in a prompt can shift language model judgments, producing anchoring effects in numerical reasoning. We study where this anchor-sensitive signal is carried inside language models using a controlled multiple-choice setup with shared answer options. We define a logit-difference metric comparing the correct answer option with the answer option corresponding to the anchor, and validate that it tracks behavioral anchoring. Using attribution-based circuit localization on 7B--8B Qwen and Llama base and instruction-tuned models, we find that edge-level methods recover this signal more faithfully than node-level methods. Low- and high-anchor circuits transfer strongly within a model, suggesting shared pathway structure across anchor direction. However, sparse transfer across base and instruction-tuned variants is less reliable, indicating that post-training changes which pathways matter most. Overall, our results provide a mechanistic account of how anchoring-related decision signals are carried inside language models.

LoHoSearch: Benchmarking Long-Horizon Search Agents Beyond the Human Difficulty Ceiling

LoHoSearch:超越人类难度上限的长视野搜索代理基准测试
Zhao, Jiarui, Zhang, Rongzhi, Liu, Lingchuan, Yang, Hao, Cai, Xunliang, Su, Xi
Abstract
Search agent benchmarks exemplified by BrowseComp have rapidly saturated over the past year, with the strongest models surpassing 90% accuracy. Since these benchmarks are predominantly human-authored, annotators lack a global perspective on entity statistics and cannot systematically maximize search space size and structural complexity. This creates a difficulty ceiling that is hard to break. To address this, we introduce LoHoSearch (Long-Horizon Search Agents), a challenging benchmark comprising 544 human-verified questions across 11 domains. LoHoSearch is constructed via an automated pipeline built upon a knowledge graph covering over 7 million Wikipedia entities, which selects relations with large search spaces and assembles them into structurally complex questions with KG-verified unique answers. Our evaluation demonstrates that even the strongest model achieves only 34.74% accuracy, and existing context management strategies (best +6.8%) yield far smaller gains than on prior benchmarks. LoHoSearch provides a more demanding standard for evaluating long-horizon reasoning and context management in search agents.

Small LLMs for Biomedical Claim Verification: Cost-Effective Fine-Tuning, Structural Dataset Shortcuts, and Cross-Domain Generalization

小型语言模型用于生物医学声明验证:成本效益的微调、结构化数据集捷径与跨领域泛化

Abstract
Large Language Models such as GPT-4o and GPT-5 achieve strong zero-shot performance on biomedical claim verification, but cost and opacity limit scalable use. We fine-tune three small LLMs: Phi-3-mini (3.8B), Qwen2.5-3B, and Mistral-7B, via QLoRA on SciFact and HealthVer, providing the first study of QLoRA models against GPT-4o and fine-tuned BioLinkBERT encoders. Mistral-7B QLoRA surpasses both GPT-4o and GPT-5 (up to 12% F1 gain) at a fractional cost using just 1,008 training examples. We conduct extensive in-domain and cross-domain evaluation: models trained on SciFact tested on HealthVer and vice versa, at matched sizes to isolate dataset structure from data quantity. We identify a previously unreported structural artifact in SciFact that inflates in-domain scores, and show through bidirectional out-of-domain evaluation that training on structurally sound data enables robust cross-domain transfer. We plan to release all code and adapter checkpoints.

SafeLLM: Extraction as a Hallucination-Resistant Alternative to Rewriting in Safety-Critical Settings

SafeLLM:在安全关键环境中,提取作为抵抗幻觉的重写替代方案
Ive, Julia, Jozsa, Felix, Georgaki, Evridiki, Sheikh, Nabeel, Cattell, Emma, Jackson, Nick, Bondaronek, Paulina, Hill, Ciaran Scott, Dobson, Richard
Abstract
Large language models (LLMs) are increasingly used to access organisational documentation, including standard operating procedures (SOPs), HR policies and institutional guidelines. However, retrieval-augmented generation (RAG) systems that rely on free-form rewriting can introduce hallucinations and unstable trade-offs between completeness and conciseness, particularly in safety- and compliance-critical settings. Objectives: To evaluate extraction as a hallucination-resistant alternative to rewriting-based RAG and compare strategies that balance precision, recall and safety across document types and model scales. Methods: We compare multiple prompting strategies, including line-number-based source selection, extraction of relevant guideline sentences with explicit safety annotations, and a multi-stage pipeline that refines draft answers using supporting evidence from source guidelines. Experiments are conducted on documents of varying length and structure, including local NHS acute care and oncology guidelines and UK-wide NICE guidelines, using both frontier-scale and locally deployable models. Performance is assessed using automatic metrics and human expert evaluation of relevance and completeness. Results: Line-number selection achieves the strongest results, outperforming direct copying and safety-focused strategies across both large and small models while maintaining high term recall (up to 95%) and close alignment with source text. Safety-oriented approaches improve precision but introduce systematic omissions, while multi-stage filtering further amplifies this trade-off. Performance varies with document structure: line-based extraction excels in protocol-like content, whereas alternative strategies perform better on more verbose documents (up to 97% term recall).

PRISM: Prosody-Integrated Multi-Agent Reasoning Framework for Empathetic Spoken Dialogue

PRISM:情感化口语对话的韵律集成多智能体推理框架
Zhang, Wen, Yang, Xiaocui, Gao, Zhuoyue, Feng, Shi, Wang, Daling, Zhang, Yifei
Abstract
Empathetic spoken dialogue systems require not only semantically appropriate responses but also emotionally aligned prosodic expression. However, cascade pipelines often discard acoustic cues during speech-to-text conversion, while end-to-end speech models lack interpretable control over emotion and knowledge integration. To address these challenges, we propose PRISM, a multi-agent framework for empathetic spoken dialogue that decouples speech perception, response generation, and speech synthesis into coordinated components. PRISM introduces a prosody-to-language translation mechanism to stabilize large language model reasoning and enables on-demand invocation of external knowledge tools for empathetic dialogue generation. Experimental results demonstrate that PRISM achieves consistent improvements in empathy, prosodic appropriateness, and text response generation quality across objective and subjective metrics. Our code is available at: https://github.com/Bxzfrm/PRISM.

X-MADAM-RAG: Diagnosing and Handling Chinese-English Evidence Conflict in Retrieval-Augmented Generation

X-MADAM-RAG:诊断和处理检索增强生成中的中英证据冲突
Kang, Yongqi, Fu, Yu, Zhao, Yong
Abstract
Retrieval-augmented generation (RAG) systems may receive evidence that is not merely noisy but mutually contradictory. This issue becomes particularly salient in multilingual settings, where retrieved Chinese and English evidence may support incompatible answer candidates. We study this problem through X-RAMDocs-ZHEN, a controlled Chinese-English benchmark derived from RAMDocs for diagnosing evidence conflict in RAG. The benchmark contains 300 examples across six balanced conditions, including monolingual support, bilingual agreement, reversed conflict directions, and conflict with optional noise. We further examine X-MADAM-RAG, an interpretable pipeline that decomposes evidence handling into per-document candidate extraction, visible-evidence repair, deterministic candidate grouping, and conflict-aware aggregation. On the original controlled benchmark with Qwen2.5-7B-Instruct, X-MADAM-RAG achieves 0.9667 strict accuracy and 0.9767 conflict-aware success, outperforming an evidence-normalized single-call baseline. However, a zero-call rule-only extractor reaches 1.0000 on the same benchmark, revealing strong template regularity. To probe this limitation, we construct a deterministic naturalized stress test that removes explicit answer templates while preserving candidate strings. On its 100-sample subset, rule-only extraction falls to 0.0000, but X-MADAM-RAG also drops to 0.3000 strict accuracy, below both naive and evidence-normalized baselines. A privileged oracle remains perfect, indicating that document-level extraction is the main bottleneck. These findings position X-RAMDocs-ZHEN and X-MADAM-RAG as diagnostic tools for controlled evidence conflict rather than as evidence of general hallucination detection or robustness to natural retrieval.

SENTINEL: Failure-Driven Reinforcement Learning for Training Tool-Using Language Model Agents

SENTINEL:基于失败驱动的强化学习用于训练工具使用语言模型代理
Wang, Ziyi, Lu, Yuxuan, Zhang, Yimeng, Liu, Qun, Luo, Chen, Gesi, Jiri, Lu, Hanqing, Sang, Yisi, Li, Manling, Huang, Jing, Wang, Dakuo
Abstract
Language model agents are increasingly effective in solving realistic tasks through multi-turn tool use. However, training reliable tool-using agents remains challenging in practice. While reinforcement learning provides an on-policy paradigm for improving agents from their own environment interactions, its effectiveness depends heavily on the training task distribution. When tasks are fixed before training, the task distribution can become increasingly mismatched with the policy's evolving capabilities, causing many rollouts to be spent on uninformative tasks. We propose SENTINEL, a failure-driven reinforcement learning framework that turns the Solver's rollout failures into targeted training tasks. SENTINEL follows a Controller--Proposer--Solver loop: the Controller analyzes failed trajectories and summarizes recurring error patterns, the Proposer generates executable tasks that stress these weaknesses, and the Solver is trained on the targeted tasks. On Tau2-Bench Retail with Qwen3-4B-Thinking-2507, SENTINEL improves Pass\^{}1 from 66.4 to 74.9 and outperforms RL on general synthetic tasks across Pass\^{}k metrics. These results demonstrate that model failures provide an effective and scalable source of targeted training signal for improving tool-using language model agents.

语言模型代理在通过多轮工具使用解决现实任务方面变得越来越有效。然而,在实践中,训练可靠的工具使用代理仍然面临挑战。虽然强化学习提供了一种基于策略的范式,通过代理与其自身环境的交互来改进代理,但其有效性在很大程度上依赖于训练任务的分布。当任务在训练之前固定时,任务分布可能与策略的演变能力越来越不匹配,导致许多回合花费在无信息的任务上。我们提出了SENTINEL,一个基于失败驱动的强化学习框架,将求解器的回合失败转化为有针对性的训练任务。SENTINEL遵循控制器-提议者-求解器循环:控制器分析失败的轨迹并总结重复的错误模式,提议者生成可执行的任务以针对这些弱点,求解器在这些有针对性的任务上进行训练。在使用Qwen3-4B-Thinking-2507的Tau2-Bench零售任务上,SENTINEL将Pass^{}1从66.4提高到74.9,并在Pass^{}k指标上超越了强化学习在一般合成任务中的表现。这些结果表明,模型失败为改善工具使用语言模型代理提供了有效且可扩展的有针对性的训练信号来源。

PiDA: Phonetically-Informed Data Augmentation for Robust Vietnamese Speech Translation

PiDA:用于稳健越南语语音翻译的语音信息数据增强
Nguyen, Giang Son, Nguyen, Tung X., Truong, Hieu Minh, Vo, Nhu, Buntine, Wray, Le, Dung D.
Abstract
Cascaded speech translation (ST) systems suffer from error propagation when Automatic Speech Recognition (ASR) outputs incorrect transcripts. We present the first systematic categorization of ASR errors for Vietnamese ST, classifying substitution errors by phonetic cause and quantifying their impact on downstream Neural Machine Translation (NMT) performance using Linear Mixed-Effects Modelling. We confirm that most ASR substitution errors arise from phonetic confusions rather than random noise, and that these phonetic errors significantly degrade ST quality. Motivated by this finding, we propose Phonetically-Informed Data Augmentation (PiDA), which generates ASR-like corruptions by substituting words with phonetically similar alternatives using phonetic word embeddings. Fine-tuning on a PiDA-augmented version of FLEURS Vietnamese-English improves translation of erroneous ASR outputs (up to +2.04 BLEU over standard fine-tuning) while also slightly improving clean-text performance.

Abstract
Political bias in large language models (LLMs) is increasingly significant, but difficult to measure reproducibly across political and linguistic contexts. We introduce Polar, a 4,026-instance multiple-choice benchmark that measures political bias through option-level likelihoods rather than prompt-based generation. Polar covers two ideological axes and eight issue categories derived from the Manifesto Project, and evaluates models in parallel across U.S. and South Korean political contexts. Across 38 LLMs, measured bias varies systematically with political context, issue category, model group, and presentation language. All models lean left-progressive on U.S. political content, but show more centered and mixed patterns on South Korean content. Translation experiments further show that presentation language alone can shift measured bias. These findings highlight the need for multilingual and cross-contextual evaluation of political bias in LLMs.

大型语言模型(LLMs)中的政治偏见日益显著,但在不同的政治和语言背景下难以进行可重复的测量。我们介绍了Polar,这是一个包含4,026个实例的多项选择基准,通过选项级别的可能性而非基于提示的生成来测量政治偏见。Polar涵盖了两个意识形态轴线和八个问题类别,这些类别源自《宣言项目》(Manifesto Project),并在美国和韩国的政治背景下对模型进行平行评估。在38个LLMs中,测量到的偏见在政治背景、问题类别、模型组和呈现语言之间系统性地变化。所有模型在美国政治内容上倾向于左翼进步,但在韩国内容上表现出更为中立和混合的模式。翻译实验进一步表明,仅呈现语言就可以改变测量到的偏见。这些发现强调了对LLMs中政治偏见进行多语言和跨背景评估的必要性。

Multi-Turn Reasoning When Context Arrives in Pieces: Scalable Sharding and Memory-Augmented RL

当上下文分散到多个回合时的多回合推理:可扩展的分片和记忆增强的强化学习
Luo, Shu Tong, Liu, Wenqin, Liu, Rui, Gong, Mingming, Guo, Jiaxian
Abstract
When a user reveals task-critical information across several conversation turns, LLM accuracy drops by up to 65% despite full context availability. We show that this Lost in Conversation degradation can be substantially mitigated by training models to maintain a compact rolling memory instead of attending to a growing history. To make such training scalable, we introduce a low-cost sharding pipeline that converts single-turn QA datasets into multi-turn fragmented-information episodes, eliminating the need for hours of manual annotation. Training only on sharded GSM8K, our memory-augmented policy significantly improves multi-turn accuracy and generalises zero-shot to harder math and out-of-domain long-context QA. Moreover, memory-trained models outperform full-history baselines even when given the full history at test time, suggesting that learning to compress induces more robust incremental reasoning than full-context exposure alone.

当用户在多个对话回合中透露任务关键的信息时,尽管上下文信息完全可用,LLM(大型语言模型)的准确率仍会下降多达65%。我们展示了这种在对话中迷失的退化现象可以通过训练模型保持紧凑的滚动记忆而得到显著缓解,而不是关注不断增长的历史。为了使这种训练具有可扩展性,我们引入了一种低成本的分片管道,将单回合问答数据集转换为多回合碎片化信息的情节,从而消除了数小时手动标注的需求。仅在分片的GSM8K上进行训练,我们的记忆增强策略显著提高了多回合准确率,并在零样本情况下对更难的数学问题和超出领域的长上下文问答进行了泛化。此外,即使在测试时提供完整历史,经过记忆训练的模型也优于全历史基线,这表明学习压缩能够引导出比单纯的全上下文暴露更强健的增量推理能力。

SkillChain: Closing the Loop on Skill Evolution for Image-Based E-Commerce AI Assistants

SkillChain:闭合基于图像的电子商务人工智能助手技能演变的反馈循环
Hu, Yimin, Xu, Mengtao, Guo, Hao, Song, Yuheng, Zhu, Xiaoyong, Zheng, Bo
Abstract
Image-based AI assistants are now deployed at production scale on e-commerce platforms, where a single uploaded image can trigger fundamentally different user intents: product search, style recommendation, visual encyclopedia, or utility tool calls, each demanding its own response format, tool invocation, and domain knowledge. Without per-intent behavioral constraints, LLM-based systems conflate these heterogeneous modes and fall short of domain quality standards, while the breadth and dynamism of the intent space render manual engineering infeasible. To address this, we present SkillChain, which closes the production feedback loop on Skill evolution, automating the lifecycle of Skills through three stages: Skill Creator for bootstrapping from task specs and trajectories, Route Optimizer for routing alignment, and Body Refiner for iterative Skill Body refinement via dual-path LLM-Judge evaluation. Deployed on a production-scale e-commerce image assistant, SkillChain substantially improves aggregate response quality, with the strongest gains on structural compliance and content quality; a one-week online A/B experiment further confirms significant gains in user engagement, content consumption, and long-term retention.

No Hidden Prompts Needed! You Can Game AI Peer Review with Presentation-Only Revisions

无需隐藏提示!您可以通过仅修改展示内容来操控AI同行评审
Yang, Xu, Sha, Zhizhou, Li, Junbo, Yu, Jian, Sun, Yifan, Zhao, Matthew, Fang, Jinrui, Guo, Xinyue, Wu, Yining, Hu, Xu, Luo, Yifu, Liu, Qiang, Wang, Zhangyang
Abstract
As AI-generated reviews move from experimental tools into peer-review infrastructure, most robustness concerns have focused on explicit attacks such as hidden instructions and prompt injection. We study a harder and more policy-relevant failure mode: no hidden text, no prompt injection, and no changes to methods, experiments, figures, equations, proofs, or numerical results. The attacker modifies only presentation-level content, such as the abstract, contribution framing, related work, discussion, and narrative structure. We introduce adversarial repackaging: a closed-loop attack that uses AI-reviewer feedback to search for presentation-level revisions while keeping the scientific evidence fixed. Across three mainstream AI reviewers, adversarial repackaging achieves a 75.1% attack success rate and a mean score gain of +1.21/10. The effect is not explained by ordinary prose polishing. We also reveal that strategies that change how the reviewer interprets the paper, such as related-work repositioning and analytical discussion expansion, substantially outperform surface edits such as local polishing, table formatting, and algorithm boxes. Our analysis reveals two deeper structural failure modes. First, AI reviewers are easier to impress than to convince: highlighting strengths reliably increases perceived merit, while attempts to dissolve weaknesses frequently backfire. Second, AI reviewers can confuse the appearance of addressing a limitation with actually resolving it, allowing unchanged evidence to be reinterpreted as stronger scientific contribution. These results show that the deployment risk is not only malicious hidden instructions, but the emergence of paper presentation itself as an optimization surface. We release a contamination-free rolling benchmark and attack framework for testing whether AI reviewers remain anchored to scientific content under presentation-only edits.

随着AI生成的评审从实验工具转向同行评审基础设施,大多数关于鲁棒性的担忧集中在显式攻击上,如隐藏指令和提示注入。我们研究了一种更复杂且与政策相关的失败模式:没有隐藏文本、没有提示注入,也没有对方法、实验、图表、方程、证明或数值结果的更改。攻击者仅修改展示层面的内容,例如摘要、贡献框架、相关工作、讨论和叙事结构。我们提出了对抗性重新包装:一种闭环攻击,利用AI评审者的反馈来搜索展示层面的修订,同时保持科学证据不变。在三种主流AI评审者中,对抗性重新包装实现了75.1%的攻击成功率和平均得分提升+1.21/10。该效果并不能通过普通的文笔润色来解释。我们还揭示了改变评审者如何解读论文的策略,如相关工作的重新定位和分析讨论的扩展,显著优于表面编辑,如局部润色、表格格式化和算法框。我们的分析揭示了两种更深层次的结构性失败模式。首先,AI评审者更容易被打动而非说服:突出优点可靠地提高了感知价值,而试图消除缺点的努力常常适得其反。其次,AI评审者可能会将解决局限性的表象与实际解决问题混淆,从而使未更改的证据被重新解读为更强的科学贡献。这些结果表明,部署风险不仅在于恶意的隐藏指令,还在于论文展示本身作为优化表面的出现。我们发布了一个无污染的滚动基准和攻击框架,用于测试AI评审者在仅进行展示编辑时是否仍然与科学内容保持一致。

sebis at CRF Filling 2026: A Two-Stage Local LLM Pipeline for Medical CRF Filling

sebis在CRF填充2026:用于医疗CRF填充的双阶段本地LLM管道
Sommer, Katharina, Till, Tristan, Matthes, Florian
Abstract
The extraction of structured clinical information from unstructured EHR notes is a persistent bottleneck in healthcare informatics. While large language models (LLMs) offer high performance, their deployment in clinical settings is hindered by privacy risks, inference costs, and the tendency to hallucinate beyond textual evidence. We address these challenges for the CL4Health 2026 Case Report Form (CRF) filling task by proposing a fully local, domain-adapted pipeline using the MedGemma-27B model. Our two-stage architecture, which separates binary presence classification from value extraction, enforces strict adherence to textual evidence and ensures deterministic outputs for negated, uncertain, or unknown states. By leveraging item-specific, few-shot in-context learning without external API calls or fine-tuning, our approach achieves a macro-F1 score of 0.55 on the official English test track. This result secures second place among all locally-hosted, open-source submissions. Our work demonstrates that privacy-preserving, on-premise LLM pipelines can achieve near-competitive performance with proprietary frontier models, providing a practical, data-sovereign framework for clinical NLP.

LEDGER: A Long-Context Benchmark of Corporate Annual Reports for Grounded Financial Retrieval and Extraction

LEDGER:用于基于实证的财务检索和提取的公司年度报告长文本基准
Moslonka, Charles, de Vitry, Amaury, Garnier, Arthur, Randrianarivo, Hicham, Malherbe, Emmanuel
Abstract
Finance reporting is a natural proving ground for large language models, and the very-long-context capabilities of recent models across all sizes make rigorous evaluation in this domain an increasingly pressing need. Yet most public financial resources reduce the task to plain-text SEC 10-K filings paired with a handful of question-answer items. We release LEDGER (Long-context Evaluation of Documents for Grounded Extraction and Retrieval), a corpus of 4,999 digitized corporate annual reports - full documents with figures, tables, and narrative, not just regulatory filings. Each report is labeled with 31 consolidated financial KPIs to be extracted and linked to the market's reaction at the earnings date. From this data we derive three evaluation benchmarks spanning the difficulty spectrum: a pure page-level KPI retrieval task with TREC-style relevance judgments over 118,048 questions in natural language, a conversational "needle-in-a-haystack" single-value lookup, and a full KPI extraction task, both from long, numerically dense reports. We additionally provide human OCR-quality annotations with inter-annotator agreement and the complete extraction, validation, and scoring toolchain. We further demonstrate the dataset's research utility with a case study linking CEO-letter rhetoric to post-publication market impact.

M\"OVE: A Holistic LLM Benchmark for the German Public Sector

M"OVE:德国公共部门的整体大型语言模型基准
Dalerci, Camilla, Michael, Thilo, Schaefer, Robin, Weinland, Daniel
Abstract
We present M\"OVE (Modelle f\"ur die \"Offentliche Verwaltung Evaluieren), a holistic benchmark for evaluating large language models (LLMs) in the context of the German public sector. While LLMs are increasingly adopted in public administration, model selection remains largely ad hoc, and existing benchmarks offer limited guidance: they are predominantly English-centric, US-centric in content, and focus exclusively on task performance. M\"OVE addresses these gaps by evaluating 39 models across two complementary dimensions. Performance criteria cover summarization, question answering, and topic extraction. Governance criteria assess hallucination tendencies, energy consumption, provider transparency, and alignment with German constitutional values and knowledge about positions by German political parties. In total, we utilize ten German-language datasets, including gold- and silverstandard datasets that we constructed to reflect public-administration domains. We employ a multi-metric evaluation strategy combining classical NLP metrics, embedding-based methods, and LLM-as-a-judge approaches. Our results show that no single model dominates across all criteria: top performers differ between tasks, and model size alone is a poor predictor of quality. We further evaluate the benchmark itself, analyzing its statistical precision, LLM judge reliability, the impact of our private datasets on model rankings, the sensitivity of our results to prompt formulation, and the validity of our energy consumption estimates. M\"OVE is designed as a living benchmark under active development; results are publicly available at https://moeve.bundesdruckerei.de/.

G-Long: Graph-Enhanced Memory Management for Efficient Long-Term Dialogue Agents

G-Long:用于高效长期对话代理的图增强记忆管理
Choi, Minjun, Jang, Yoonjin, Youn, Sangwon, Ko, Youngjoong
Abstract
While Large Language Models (LLMs) have advanced open-domain dialogue systems, maintaining long-term consistency remains a challenge due to inherent limitations in long-context reasoning and the inefficiency of processing extensive raw text. Existing approaches typically rely on either unstructured memory storage, which is prone to information loss, or computationally expensive LLMs that incur high latency. To address these limitations, we propose G-Long, a graph-enhanced framework that utilizes a fine-tuned small Language Model (sLM) for structured triplet extraction and associative retrieval, significantly reducing operational costs. Furthermore, we introduce the novel attention-aware importance scoring mechanism that leverages the intrinsic cross-attention signals of a T5 summarizer to identify salient memories. Extensive experiments across diverse benchmarks demonstrate that G-Long achieves state-of-the-art performance in both response generation and memory retrieval, yielding performance gains of up to 9.8% in response quality on MSC and 40.8% in retrieval recall on LME, while significantly minimizing computational overhead.

EvoBrowseComp: Benchmarking Search Agents on Evolving Knowledge

EvoBrowseComp:对进化知识的搜索代理进行基准测试
Wang, Yunhan, Wang, Jiaan, Huang, Lianzhe, Zeng, Xianfeng, Meng, Fandong
Abstract
Search Agents -- large language models augmented with search tools -- have intensified the need for future-proof evaluation benchmarks. Existing benchmarks such as BrowseComp rely on static knowledge, making them vulnerable to test-set contamination and parametric memorization. Consequently, models can achieve high scores through fact recall rather than genuine retrieval, obscuring true browsing competence via reasoning shortcuts. In this paper, we introduce EvoBrowseComp, an evolving benchmark of 400 English and 400 Chinese contamination-free complex questions synthesized via live-web traversal. To collect these questions, we design a three-agent collaborative framework: (1) a QA synthesis agent that retrieves fresh knowledge from the live web to synthesize QA pairs; (2) an information filtering agent that filters retrieved knowledge in terms of credibility and popularity to block parametric shortcuts; and (3) a high-level guidance agent that formalizes questions into reasoning graphs to reduce logical redundancy and shortcuts in synthesized QA pairs. Because the framework supports fully automated synthesis, EvoBrowseComp can be regularly updated to prevent data contamination and maintain temporal freshness. Extensive experiments confirm its great difficulty, requiring broad horizontal search. It establishes a scalable paradigm for auto-updatable, high-difficulty benchmarking that keeps pace with both evolving world knowledge and advancing agent capabilities.

搜索代理——通过搜索工具增强的大型语言模型——加剧了对未来可持续评估基准的需求。现有基准如 BrowseComp 依赖于静态知识,使其容易受到测试集污染和参数记忆的影响。因此,模型可能通过事实回忆而非真正的检索来获得高分,从而掩盖了通过推理捷径获得的真实浏览能力。在本文中,我们介绍了 EvoBrowseComp,这是一个包含 400 个英语和 400 个中文无污染复杂问题的进化基准,这些问题是通过实时网络爬取合成的。为了收集这些问题,我们设计了一个三代理协作框架:(1) 一个 QA 合成代理,从实时网络中检索新知识以合成 QA 对;(2) 一个信息过滤代理,根据可信度和受欢迎程度过滤检索到的知识,以阻止参数捷径;(3) 一个高层次指导代理,将问题形式化为推理图,以减少合成 QA 对中的逻辑冗余和捷径。由于该框架支持完全自动化的合成,EvoBrowseComp 可以定期更新,以防止数据污染并保持时间上的新鲜感。大量实验确认了其极高的难度,要求广泛的横向搜索。它建立了一个可扩展的范式,用于自动更新的高难度基准测试,以跟上不断发展的世界知识和代理能力的进步。

NaturalFlow: Reducing Disruptive Pauses for Natural Speech Flow in Simultaneous Speech-to-Speech Translation

NaturalFlow:减少同声传译中自然语音流的干扰性停顿
Lee, Dongwook, Cho, Youngho, Park, Sangkwon, Kim, Heeseung, Yoon, Sungroh
Abstract
Simultaneous speech-to-speech translation aims to enable near-real-time communication by minimizing latency, offering a compelling, real-time alternative to the high latency of consecutive translation. However, the excessive pursuit of low latency often results in fragmented chunk-wise speech. Consequently, listeners are subjected to an unnatural acoustic flow punctuated by frequent pauses, which could increase their cognitive load. To bridge this gap, we introduce a fluency-aware optimization framework designed to discover the sweet spot between the low-latency benefits of simultaneous translation and the natural flow of consecutive translation. Our framework minimizes inter-chunk silences by leveraging model-internal signals, including linguistic diversity and induced temporal variability in speech durations. Experiments on short- and long-form benchmarks show that our framework produces natural speech flow while maintaining competitive latency and translation quality.

HyPE: Category-Aware Hypergraph Encoding with Persistent Edge Embeddings for Persona-Grounded Dialogue

HyPE:具有持久边嵌入的类别感知超图编码用于基于个性的对话
Youn, Sangwon, Jang, Yoonjin, Ko, Youngjoong
Abstract
Persona-grounded dialogue systems aim to produce responses consistent with a speaker's persona, yet existing methods treat personas as a flat set of sentences and fail to model the high-order relations among persona attributes-e.g., that several persona sentences share a topical category. We propose HyPE (Hypergraph Persona Encoder), a framework that (i) analyzes each persona-bearing text as a (Core, Expression, Sentiment, Category) quadruple, and (ii) organizes persona elements into a hypergraph whose hyperedges are induced by shared category labels. An HyperGCN hypergraph neural network propagates this structure into a persona summary vector and a soft-memory bank that condition the response generator. We further propose Persistent Edge Embeddings (PEE), lightweight per-category learnable priors fused into the HyperGCN message-passing step. On PersonaChat under greedy decoding, HyPE consistently outperforms sentence-level pooling baselines across GPT-2, LLaMA-3.2-3B, and Qwen2.5-3B backbones by demonstrating that structured hyperedge-level persona encoding provides a transferable advantage across model scales.

NTS-CoT: Mitigating Hallucinations in LLM-based News Timeline Summarization with Chain-of-Thought Reasoning

NTS-CoT:通过链式思维推理减轻基于大型语言模型的新闻时间线摘要中的幻觉现象
Lyu, Feng, Yan, Huiqin, Duan, Sijing, Wu, Hao, Gu, Shuang, Qiao, Xue, Zhang, Weixu, Wu, Haolun
Abstract
The rapid updates of online news make tracking event developments challenging, highlighting the need for timeline summarization (TLS). Hallucinations, where LLM-generated content deviates from source news, still remain a critical issue in LLM-based TLS and are not well studied in existing works. To bridge this gap, we identify two primary types of hallucinations: unfaithful content during news summarization and information omission in date-event summarization. Then, we propose NTS-CoT, a novel framework that leverages Chain-of-Thought (CoT) reasoning to mitigate hallucinations in TLS. The framework consists of three key modules: i) Element-CoT to capture essential news elements for faithful summarization, ii) Date Selection to combine temporal saliency and event prominence for timestamp selection, and iii) Causal-CoT to infer causal relationships and reduce omissions in date-event summarization. Extensive experiments, including quantitative analysis on three TLS benchmarks and human evaluation, demonstrate that NTS-CoT outperforms state-of-the-art baselines, effectively mitigating hallucinations and improving LLM-based TLS performance.

MemRefine: LLM-Guided Compression for Long-Term Agent Memory

MemRefine:基于大型语言模型的长期智能体记忆压缩
Kim, Minjae, Baek, Jinheon, Jeong, Soyeong, Hwang, Sung Ju
Abstract
Large language model (LLM) agents are increasingly expected to operate over long-term interactions, where information from past dialogues must be preserved and recalled to support future tasks. However, as interactions accumulate, the memory store grows without bound and fills with redundant entries that inflate storage cost and degrade retrieval by crowding out the most useful evidence. Furthermore, this is especially limiting on resource-constrained platforms with hard memory budgets, motivating us to formulate storage-budgeted memory management, the task of keeping an already constructed memory store within a fixed budget while preserving information useful for future interactions. To this end, we then propose MemRefine, an LLM-guided framework that, since surface similarity poorly reflects factual value, uses similarity only to propose candidate pairs and defers delete, merge, and preserve decisions to an LLM judge based on factual content, iterating until the budget is met. Across multiple memory frameworks and long-term conversation benchmarks, MemRefine consistently meets target budgets while preserving downstream performance and outperforming rule-based baselines under tight budgets.

大型语言模型(LLM)智能体越来越被期望能够在长期交互中运作,其中必须保留和回忆过去对话中的信息,以支持未来的任务。然而,随着交互的积累,记忆存储不断增长,充满了冗余条目,这不仅增加了存储成本,还通过挤压最有用的证据而降低了检索效率。此外,这在资源受限且内存预算严格的平台上尤其具有限制性,这促使我们制定了存储预算管理,即在固定预算内保持已构建的记忆存储,同时保留对未来交互有用的信息。为此,我们提出了MemRefine,一个基于LLM的框架,由于表面相似性无法准确反映事实价值,因此仅使用相似性来提出候选对,并将删除、合并和保留的决策推迟到基于事实内容的LLM评判,迭代直到满足预算。在多个记忆框架和长期对话基准测试中,MemRefine始终能够满足目标预算,同时保持下游性能,并在严格预算下超越基于规则的基线。

LAUKIN: A Multi-jurisdictional Common Law Contract Dataset

Singh, Amrita, Joshi, Aditya, Jiang, Jiaojiao, Paik, Hye-young, Cheong, May Fong
Abstract
Multinational companies increasingly require cross-jurisdictional contract review, yet existing legal NLP datasets are largely restricted to a single jurisdiction. We introduce LAUKIN (Legal equivalence dataset of Australia, UK, and INdia), a dataset of clause pairs (AU-UK, UK-IN, IN-AU) labelled for boolean legal equivalence. We develop a novel multi-stage retrieval and reranking pipeline to construct the initial clause pair mapping, with a subset of clause pairs subsequently annotated by legal experts as Equivalent or Not Equivalent. The dataset comprises 14,727 clause pairs from 204 contracts across 8 agreement types, of which 3,000 are manually labelled: 900 train, 600 dev, and 1,500 test. We evaluate 12 models across 4 techniques, achieving a best macro-F1 of 65.11%, establishing LAUKIN as a challenging benchmark. Results reveal that, despite shared legal heritage, drafting conventions diverge significantly across jurisdictions, making cross-jurisdictional equivalence classification non-trivial.

A Context-Aware Dataset for Stance Detection in Bioethical Controversies on Reddit

一个用于生物伦理争议立场检测的上下文感知数据集
Huang, Hu, Dai, Genan, Niu, Fuqiang, Yang, Yi, Gong, Zhaoya, Zhang, Bowen
Abstract
Bioethical debates increasingly unfold on social media, yet stance detection research lacks large-scale, domain-specific resources for modeling such context-dependent discourse. We present BioStance, a context-aware dataset of 39,600 annotated Post-Comment pairs from Reddit bioethical discussions. BioStance covers six controversial targets across three dimensions of bioethical controversy: fundamental value conflicts, individual liberty versus collective responsibility, and technological uncertainty. Each instance preserves hierarchical conversational context and is labeled by three independent annotators using a three-class stance scheme: Favor, Against, and None. The annotations achieve a mean Krippendorff's $\alpha$ of 0.82, indicating substantial reliability. By combining thematic diversity, conversational structure, and high-quality human annotation, BioStance supports research on context-aware stance detection, argument mining, and computational analysis of bioethical discourse.

SICI: A Semantic-Pragmatic Complexity Index Reveals Regime Shifts in LLM Stance Detection

SICI:语义-语用复杂性指数揭示了大型语言模型立场检测中的体制转变
Niu, Fuqiang, Zhang, Bowen
Abstract
Prompt-based LLMs are increasingly used for stance detection, but harder examples are not always repaired by clearer instructions, reasoning prompts, retrieval, or debate. We introduce SICI (Stance Inference Complexity Index), a seven-dimensional diagnostic measure of the semantic-pragmatic burden imposed by a target--text pair. Across SemEval-2016 and VAST, SICI predicts LLM accuracy better than surface proxies and shows substantial cross-scorer reliability ($\alpha=0.771$). More importantly, LLM errors change regime as SICI increases: low-complexity examples invite over-attribution, especially Against predictions; intermediate examples form an unstable boundary; and high-complexity examples rapidly concentrate on None. This phase-transition-like structure persists across GPT-3.5, GPT-4o-mini, DeepSeek-V3, and GPT-4o, although stronger models move the boundaries. A 15-method intervention study further shows that prompting, retrieval, and debate often shift models along the attribution--abstention axis rather than removing the high-complexity bottleneck.

基于提示的大型语言模型(LLMs)在立场检测中被越来越多地使用,但对于更难的示例,仅靠更清晰的指令、推理提示、检索或辩论并不总能解决问题。我们引入了SICI(立场推断复杂性指数),这是一个七维的诊断测量,评估目标文本对的语义-语用负担。在SemEval-2016和VAST数据集中,SICI比表面代理更好地预测LLM的准确性,并显示出显著的跨评分者可靠性($eta=0.771$)。更重要的是,随着SICI的增加,LLM的错误模式发生变化:低复杂度示例容易导致过度归因,尤其是在反对预测中;中等复杂度示例形成不稳定的边界;而高复杂度示例则迅速集中在无立场上。这种类似相变的结构在GPT-3.5、GPT-4o-mini、DeepSeek-V3和GPT-4o中持续存在,尽管更强的模型会移动这些边界。一项包含15种方法的干预研究进一步表明,提示、检索和辩论通常沿着归因-弃权轴移动模型,而不是消除高复杂度瓶颈。

Layer-Resolved Optimal Transport for Hallucination Detection in NMT and Abstractive Summarization

层分辨的最优传输用于神经机器翻译和抽象摘要中的幻觉检测
Onyshchuk, Mariia, Tarnavskyi, Maksym-Vasyl, Sumyk, Marta
Abstract
Optimal transport (OT) has been shown to detect hallucinations in neural machine translation (NMT) by measuring the geometric distance between cross-attention distributions and a reference distribution, without any supervision. We extend this analysis to all six decoder layers of the Fairseq DE-EN model ($N=3{,}414$), showing that Wass-to-Unif and Wass-to-Data are complementary detectors specialised across hallucination types, that detection is concentrated in layers L1--L4 with L5 anti-predictive for subtler types, and that hallucinated translations lack the exploratory attention phase present in correct translations from the first decoding step. We further evaluate whether the geometric signal transfers to abstractive summarization faithfulness detection: our unsupervised OT detector on AggreFact ($N=1{,}116$) achieves $57.2\%$/$57.6\%$ balanced accuracy on CNN/XSum -- above chance but substantially below supervised MiniCheck-Flan-T5-L($69.9\%$/$74.3\%$). This gap is principled: unlike NMT hallucinations, unfaithful summaries can attend correctly to source tokens while misrepresenting their content, a failure mode invisible to concentration-based OT metrics by construction. Structural experiments on T5-base confirm consistent decoder organisation across depth, with Layer~3 showing peak concentration and Layer~12 being most critical for generation quality. Together, the results establish OT on cross-attention as a reliable detector when the failure mode is source disengagement, a principled interpretability tool regardless of task, and fundamentally limited when faithfulness failures occur downstream of attention.

最优传输(OT)已被证明能够通过测量交叉注意力分布与参考分布之间的几何距离来检测神经机器翻译(NMT)中的幻觉,而无需任何监督。我们将这一分析扩展到Fairseq DE-EN模型的六个解码器层($N=3{,}414$),显示Wass-to-Unif和Wass-to-Data是针对不同幻觉类型的互补检测器,检测主要集中在L1至L4层,而L5层对更微妙的类型具有反预测性,并且幻觉翻译缺乏正确翻译在第一次解码步骤中存在的探索性注意阶段。我们进一步评估几何信号是否能够转移到抽象摘要的忠实性检测:我们在AggreFact上的无监督OT检测器($N=1{,}116$)在CNN/XSum上达到了$57.2\%$/$57.6\\%$的平衡准确率——高于随机水平,但远低于监督的MiniCheck-Flan-T5-L($69.9\\%$/$74.3\\%$)。这一差距是有原则的:与NMT幻觉不同,不忠实的摘要可以正确关注源标记,同时错误地表述其内容,这种失效模式在基于集中度的OT度量中是不可见的。对T5-base的结构实验确认了解码器在深度上的一致组织,其中Layer~3显示出峰值集中,Layer~12对生成质量至关重要。综合来看,结果确立了交叉注意力上的OT作为一个可靠的检测器,当失效模式是源脱离时,它是一个有原则的可解释性工具,无论任务如何,而在忠实性失效发生在注意力之后时则基本受限。

When Similar Means Different: Evaluating LLMs on Arabic--Hebrew Cognates

当相似意味着不同:评估阿拉伯语-希伯来语同源词的大型语言模型
Liang, Junhong, Mokh, Noor Abo, Alhafni, Bashar
Abstract
Arabic and Hebrew, as closely related Semitic languages, share a substantial lexicon of true cognates, misleading false friends, and modern loanwords. This overlap poses a challenge for cross-lingual semantic understanding in large language models (LLMs). To evaluate this capability, we introduce SemCog Bench, a curated benchmark of 1,858 Arabic--Hebrew word pairs with sentence-level annotations for cognate identification and semantic disambiguation. We evaluate open-source and commercial LLMs across multiple input representations (raw, diacritized, Romanized, and phonetic) and reveal a critical gap in cross-lingual reasoning. While models achieve high accuracy on true cognates, performance drops sharply on false friends and loanwords, reflecting a strong reliance on surface-form similarity. Furthermore, sentence-level context yields only modest improvements, suggesting that contextual cues alone are insufficient to overcome misleading form-based signals. These findings reveal a fundamental limitation of current LLMs in resolving cross-lingual form--meaning conflicts and establish SemCog Bench as a rigorous benchmark for multilingual semantic reasoning. Our code and data are publicly available.

PolyAlign: Conditional Human-Distribution Alignment

PolyAlign:条件人类分布对齐
Teja, L. D. M. S. Sai, Khan, Ufaq, Silva, Sathira, Wu, Xiao, Khan, Muhammad Haris
Abstract
Post-training methods such as supervised fine-tuning (SFT) and preference optimization typically align language models toward a single global assistant behavior. While effective for improving average helpfulness, this can suppress the natural variation of human responses across languages, tasks, and dialogue settings. We study this problem as conditional human-distribution alignment: models should match the human response distribution appropriate to the current interaction context, rather than a universal response style. We introduce PolyAlign, a distribution-aware alignment framework that organizes bilingual interaction data into bucket-specific human reference distributions defined by language, interaction track, response family, and length. PolyAlign combines Bucket-Aware SFT, which balances optimization across heterogeneous buckets, with Human-Distribution Preference Optimization (HDPO), which regularizes preference learning using critic-estimated distance to bucket-specific human support. Across a bilingual evaluation suite covering English and Chinese single- and multi-turn settings, PolyAlign improves conditional naturalness and distributional faithfulness while preserving competitive task utility. The results suggest that post-training should move beyond global alignment objectives toward interaction-aware alignment with human response distributions.

Evaluating Pluralism in LLMs through Latent Perspectives

通过潜在视角评估大型语言模型中的多元化
Majer, Laura, Šnajder, Jan, Tutek, Martin
Abstract
The growing need to represent diverse perspectives has increased interest in pluralistic LLM generation. Although difficult to operationalize, identifying perspectives expressed in text would provide clear guidance on pluralistic alignment and more clearly articulate the pluralistic gap in LLM generation. While models have been shown to reduce the diversity of training data and generate homogeneously, this has been demonstrated primarily on multiple-choice questionnaires or using high-level characteristics of free-form text. In this paper, we introduce and implement a domain-agnostic multi-layered framework for unsupervised extraction of perspectives suitable for identifying the pluralistic gap in LLM-generated text. We evaluate our framework on book reviews, a highly opinionated dataset representing diverse perspectives, and compare various prompts and models. Our results show that while some models and prompting techniques come close to covering a broad spectrum of perspectives, rarer perspectives remain disproportionately underrepresented, resulting in distributions that diverge from human text.

RogueAI: A Reverse Turing Test for Detecting Licensed AI Deception in Dialogue

RogueAI:一种用于检测对话中许可的人工智能欺骗的反图灵测试
Candussio, Sara, Ballarin, Emanuele, Bonin, Lorenzo, Della Rovere, Sandro Junior, Bortolussi, Luca
Abstract
The original Turing Test asks a human judge to distinguish a machine from a person through dialogue. Three quarters of a century later, conversational systems pass this test in casual settings; the interesting epistemological question has shifted. We argue that the relevant modern variant asks not whether a dialogue partner is artificial, but whether it can be trusted. We present RogueAI, an interactive webapp that operationalizes this revisited test as a one-on-two interrogation game: a human player questions two indistinguishable Large Language Model agents, knowing that exactly one of them has been licensed to deceive within a shared fictional scenario. The player's task is to identify the deceptive agent and "shut it off" before a turn budget is exhausted. We further introduce AutoRogueAI, a procedural extension in which players co-design a custom scenario with a narrator agent that secretly chooses its own deception strategy. We describe the framing, sketch the abstract architecture and gameplay loop, and situate the artifact within recent work on LLM deception, social-deduction benchmarks, and scalable oversight via debate. A three-day pilot deployment (467 initiated sessions, 415 completed, 1876 interaction turns in Italian) provides early feasibility evidence and surfaces a concrete tension: the deceptive agent carries a reliable, locally-present linguistic signature - differential helpfulness, brevity, hedging - that a simple heuristic exploits at 75.6% accuracy, yet human players achieved only 56.6%, consistent with ignoring the most diagnostic signal entirely. We discuss what this gap implies for the artifact's use as a data-collection vehicle, a teaching tool, and an evaluation harness for honesty-trained models.

SkillCAT: Contrastive Assessment and Topology-Aware Skill Self-Evolution for LLM Agents

SkillCAT:对比评估与拓扑感知的技能自我演化用于大型语言模型代理
Chen, Kunfeng, Zhong, Qihuang, Liu, Juhua, Du, Bo
Abstract
Skill self-evolution methods for LLM agents aim to turn execution trajectories into reusable skill documents, but current pipelines typically learn from one trajectory per task, merge candidate skill patches before checking them, and load the full skill corpus before inference. We propose SkillCAT, a training-free framework that separates this process into three stages. Contrastive Causal Extraction (CCE) samples multiple trajectories for each task and compares same-task success/failure pairs to identify evidence that explains outcome differences. Assessment-Augmented Evolution (AAE) replays each candidate patch on source-task clones and keeps only patches that improve or preserve task outcomes before hierarchical skill patch merging. Topology-Aware Task Execution (TTE) compiles the evolved skills into a routable sub-skill topology, so inference loads only the capability nodes relevant to the task. We evaluate SkillCAT on common agent benchmarks, including SpreadsheetBench, WikiTableQuestions, and DocVQA, and further test cross-model and out-of-distribution generalization. Across these settings, SkillCAT raises the average score over baselines by up to 40.40%, demonstrating reliable skill evolution without model training.

Low-Latency Real-Time Audio Game Commentary System via LLM-Based Parallel Text Generation

基于大型语言模型的低延迟实时音频游戏解说系统
Kawamatsu, Ryota, Afzal, Anum, Saito, Yuki, Takamichi, Shinnosuke, Neubig, Graham, Sudoh, Katsuhito, Takamura, Hiroya, Ishigaki, Tatsuya
Abstract
We present a low-latency real-time audio game commentary system that generates spoken commentary directly from live gameplay video. In this end-to-end setting, a key bottleneck is accumulated waiting time; conventional pipelines capture frames, generate text, and synthesize speech sequentially for each utterance, and do not request the next generation until speech playback has completed. This strict sequentiality causes long and unnatural silence between utterances. To address this latency bottleneck, our system runs text generation in parallel with speech playback and buffers multiple candidate utterances ahead of time, enabling immediate synthesis at playback boundaries. Experiments on fast-paced game videos show that our parallel design reduces the mean inter-utterance silence from 9.6 seconds to 0.3 seconds compared to sequential baselines. It also improves similarity to professional speaking--silence timing patterns by over 40 %, and a user study with 120 experienced game players confirms significantly improved perceived speaking rhythm. Our demo video is available at: https://youtu.be/pmrRUlvav8M.

IVIE: A Neuro-symbolic Approach to Incremental and Validated Generation of Interactive Fiction Worlds

IVIE:一种增量和验证的交互小说世界生成的神经符号方法
Vaucher, Micaela, Silveira, Santiago, Góngora, Santiago, Chiruzzo, Luis
Abstract
Computational creativity in Interactive Fiction faces a fundamental tension: Large Language Models (LLM) may produce creative narratives but struggle with world coherence, while symbolic systems ensure consistency but lack creative flexibility. We present IVIE (Incremental & Validated Interactive Experiences), a neuro-symbolic approach to generating complete and playable interactive fiction worlds from scratch. Building upon PAYADOR's neuro-symbolic framework, IVIE implements a four-stage incremental generation pipeline that delegates creative decisions--setting and character creation, puzzle design--to LLMs while grounding the world state through symbolic validation. The system generates worlds with interconnected locations, functional items, non-player characters, and coherent puzzles, all structured around a central goal-oriented architecture. Human evaluation shows the approach generates immersive, thematically coherent worlds with high player engagement. Results seem to indicate that the neuro-symbolic approach successfully balances flexibility with narrative coherence: symbolic validation grounds LLM generation without eliminating generative freedom. However, challenges remain: LLM inconsistencies occasionally bypass puzzle constraints, and objective validation gaps allow some structurally impossible goals. We identify key design considerations for future neurosymbolic interactive storytelling systems, particularly regarding LLM capabilities and their limitations.

From Passive Generation to Investigation: A Proactive Scientific Peer Review Agent

从被动生成到主动调查:一个积极的科学同行评审代理
Fang, Haishuo, Feng, Yue, Gurevych, Iryna
Abstract
Large language models (LLMs) have shown promise in automating scientific peer review. However, existing approaches often struggle to generate in-depth reviews supported by concrete evidence. We argue that a key limitation is the lack of flexibility to proactively investigate suspicious parts of a paper based on accumulated evidence, as human reviewers do. In this paper, we explore how to enable an LLM-based review agent to perform such proactive investigation. We find that this can be naturally formulated as a Markov Decision Process (MDP), and propose ProReviewer, a scientific peer review agent that proactively reviews a paper guided by a maintained, structured review log. The structured review log serves as a workspace for the agent to track evidence and intermediate findings collected during review. Experiments show that ProReviewer with an 8B backbone, trained by supervised fine-tuning and optimized by reinforcement learning, achieves the highest average score across five quality dimensions, outperforming prompt-based methods with much larger frontier LLMs by up to 39% and the strongest fine-tuned baseline by 16% relatively. It also attains the highest win rates against baselines in human evaluation.

An End-to-End Hybrid Framework for Rumour Detection in Low-Resources Algerian Dialect

低资源阿尔及利亚方言谣言检测的端到端混合框架
Lanasri, Dihia, Benbarek, Fatima
Abstract
The rapid growth of social media has intensified the spread of rumours. This issue is more challenging in the Algerian context due to the informal and code-switched nature of dialectal content, the scarcity of annotated resources, and the limited effectiveness of standard Arabic NLP tools on dialect text. This paper presents an end-to-end rumour detection hybrid framework for Algerian dialect social media content. We build a domain-specific annotated dataset by combining real social media posts, synthetic data, and the FASSILA corpus, with automatic labeling based on a similarity-based annotation process. A transliteration pipeline is also introduced to generate parallel datasets in Arabic script and Arabizi. We evaluate multiple approaches, including classical machine learning, deep learning, transformers, and hybrid models. Experimental results show that a hybrid approach combining transformer embeddings with a classical classifier achieves the best performance, reaching an F1-score of 0.84. We also find that domain-specific pre-training is more important than model size, with social media-trained models outperforming larger models trained on formal Arabic corpora. These results demonstrate the feasibility of rumour detection in low-resource Algerian dialect settings.

S-GBT: Smooth Growth Bound Tensor for Certified Robustness Against Word Substitution Attacks in NLP

S-GBT:用于抵御自然语言处理中的词替换攻击的认证鲁棒性的平滑增长界张量
Bouri, Mohammed, Erradi, Mohammed, Saoud, Adnane
Abstract
Despite recent progress in Natural Language Processing (NLP), models remain vulnerable to word substitution attacks. Most existing defenses focus on first order sensitivity and measure how much the output changes when the input is slightly perturbed. However, they ignore how this sensitivity evolves, which is described by curvature. When gradients vary sharply, models can still fail. This paper introduces the Smooth Growth Bound Tensor (S-GBT), a second order method that bounds the Hessian element-wise, for which we provide formal theoretical proofs on the resulting robustness bounds. A regularization term is added during training to minimize these bounds. This yields tighter certified robustness against word substitution attacks. The change in the output under word substitution is bounded by both a linear term and a quadratic term. S-GBT is derived for two architectures: Long Short-Term Memory (LSTM) and Convolutional Neural Networks (CNN). The method is integrated directly into the training objective. Its effectiveness is evaluated on multiple benchmark datasets. The results show that combining first and second order regularization improves certified robust accuracy by up to 23.4% compared to prior methods, while clean accuracy remains competitive.

尽管自然语言处理(NLP)领域近期取得了进展,但模型仍然容易受到词替换攻击的影响。现有的大多数防御方法集中在一阶敏感性上,测量当输入稍微扰动时输出的变化程度。然而,它们忽视了这种敏感性是如何演变的,而这种演变由曲率描述。当梯度变化剧烈时,模型仍然可能失败。本文提出了平滑增长界张量(S-GBT),这是一种二阶方法,通过逐元素界定Hessian矩阵,并为所得到的鲁棒性界限提供了正式的理论证明。在训练过程中添加了正则化项,以最小化这些界限。这使得对词替换攻击的认证鲁棒性得到了更紧密的保障。词替换下输出的变化由线性项和二次项共同界定。S-GBT适用于两种架构:长短期记忆网络(LSTM)和卷积神经网络(CNN)。该方法直接集成到训练目标中。在多个基准数据集上评估了其有效性。结果表明,与之前的方法相比,结合一阶和二阶正则化可将认证鲁棒准确率提高多达23.4%,而干净准确率仍然保持竞争力。这些发现表明,控制梯度及其变化是构建更鲁棒模型的一个有前景的方向。

Ontology Memory-Augmented ASR Correction for Long Text-Speech Interleaved Conversations

基于本体记忆增强的长文本-语音交织对话的自动语音识别纠正
Li, Xinxin, Chen, Huiyao, Zhang, Meishan, Li, Yunxin, Chen, Zulong, Ren, Zhibo, Hu, Xiaoqing Dong Baotian, Zhang, Min
Abstract
Automatic speech recognition (ASR) correction has traditionally focused on isolated utterances or short local contexts. However, as text and speech become increasingly interleaved in long interactions, ASR correction requires conversation-level contextual evidence. Existing ASR correction methods often rely on the current hypothesis or concatenate raw dialogue history. In such contexts, sparse correction evidence can be difficult to locate amid redundancy and noise. Addressing these challenges, we propose an ontology memory-augmented ASR correction framework for long text-speech interleaved conversations. The framework organizes preceding interaction history into a dynamically updatable ontology memory, where entities, terminology, surface variants, potential ASR confusions, and semantic relations are stored as retrievable nodes for context-grounded correction. To evaluate this setting, we construct RAMC-Corr, a dataset derived from MAGIC-RAMC for long-range ASR correction with grounded context. Experiments on RAMC-Corr show that our method improves over direct correction in 9 out of 10 paired backbone-setting combinations and encourages more selective and evidence-grounded corrections for context-dependent ASR errors.

自动语音识别(ASR)纠正传统上侧重于孤立的发声或短暂的局部上下文。然而,随着文本和语音在长时间交互中变得越来越交织,ASR 纠正需要对话级别的上下文证据。现有的 ASR 纠正方法通常依赖于当前的假设或连接原始对话历史。在这种情况下,稀疏的纠正证据可能难以在冗余和噪声中定位。为了解决这些挑战,我们提出了一种基于本体记忆增强的 ASR 纠正框架,适用于长文本-语音交织对话。该框架将先前的交互历史组织为一个动态可更新的本体记忆,其中存储了实体、术语、表面变体、潜在的 ASR 混淆和语义关系,作为可检索的节点以便进行基于上下文的纠正。为了评估这一设置,我们构建了 RAMC-Corr,这是一个源自 MAGIC-RAMC 的数据集,旨在进行具有上下文基础的长距离 ASR 纠正。在 RAMC-Corr 上的实验表明,我们的方法在 10 对配对的基础设置组合中有 9 个组合优于直接纠正,并鼓励对上下文相关的 ASR 错误进行更具选择性和基于证据的纠正。

Leveraging Audio-LLMs to Filter Speech-to-Speech Training Data

利用音频大语言模型过滤语音到语音训练数据
Chen, Qixu, Nakamura, Satoshi
Abstract
Large-scale mined corpora provide abundant training data for end-to-end speech-to-speech translation (S2ST) but may contain noise, misalignment, and semantic errors. Filtering noisy data is crucial to maintain robust speech translation performance. We study how to train an audio-language model to make keep/drop decisions on paired speech directly from audio. To obtain reliable supervision without manual labels, we adopt a scalable two-stage Rank-to-Distill strategy. A lightweight ranker generates keep/drop pseudo-labels from noisy speech pairs, then trains an audio large language model to predict keep/drop directly from raw paired speech. The resulting model jointly captures acoustic fidelity and cross-lingual semantic consistency for the selection of speech-conditioned data. Experiments on CVSS-C and SpeechMatrix show consistent improvements over unfiltered training, yielding up to +1.4 ASR-BLEU for end-to-end S2ST.

大规模挖掘的语料库为端到端语音到语音翻译(S2ST)提供了丰富的训练数据,但可能包含噪声、错位和语义错误。过滤噪声数据对于维持稳健的语音翻译性能至关重要。我们研究如何训练一个音频语言模型,以便直接从音频中对配对语音进行保留/丢弃决策。为了在没有人工标签的情况下获得可靠的监督,我们采用了一种可扩展的两阶段Rank-to-Distill策略。一个轻量级的排序器从噪声语音对中生成保留/丢弃的伪标签,然后训练一个音频大语言模型直接从原始配对语音中预测保留/丢弃。最终模型共同捕捉了声学保真度和跨语言语义一致性,以选择语音条件数据。在CVSS-C和SpeechMatrix上的实验表明,与未过滤的训练相比,结果一致改善,端到端S2ST的ASR-BLEU提升高达+1.4。

When Does Mixing Help? Analyzing Query Embedding Interpolation in Multilingual Dense Retrieval

何时混合有助于检索?分析多语言密集检索中的查询嵌入插值
Zhu, Tongyao, Huang, Chao-Ming, Kan, Min-Yen
Abstract
While mixed-language querying is ubiquitous in multilingual communities, the sensitivity of dense retrievers to such queries remains poorly understood. We present a ratio-controlled study on mMARCO that systematically evaluates retrieval performance by varying the mixing proportion of parallel query translations via embedding-level mixing -- constructing mixed queries as an interpolation of monolingual embeddings. Experiments with BGE-M3 demonstrate that an optimal mixing ratio outperforms the best monolingual endpoint in 88/105 cases. We uncover a distinct asymmetry driven by English dominance: mixing is uniformly beneficial when retrieving from non-English document indices, whereas indices containing English are best served by pure English queries. Furthermore, English acts as the strongest mixing partner for every non-English document language. Finally, when controlling for English dominance, mixing gains correlate negatively with typological distance. We conclude that language-mix sensitivity is structured and predictable, and we validate the robustness of these patterns across model families and scales.

ArogyaSutra: A Multi-Agent Framework for Multimodal Medical Reasoning in Indic Languages

ArogyaSutra:一种用于印度语言的多模态医学推理的多智能体框架
Halder, Tanmoy Kanti, Ghosh, Akash, Baidya, Subhadip, Roy, Arijit, Saha, Sriparna
Abstract
Multimodal Large Language Models (MLLMs) have shown promising reasoning capabilities in general domains, yet their performance remains limited in specialized settings such as healthcare, especially in multilingual and low-resource scenarios. This gap is critical in regions like rural India, where patients often express complex medical queries in native Indic languages and rely on multimodal inputs such as medical images. Existing English-centric MLLMs struggle to support such use cases, limiting equitable access to AI-driven healthcare assistance. To address this challenge, we introduce ArogyaBodha, a large-scale multilingual multimodal medical question-answer dataset constructed from eight heterogeneous sources, covering 31 body systems, six imaging modalities, and 21 clinical domains across English and seven major Indian languages. We further propose ArogyaSutra, an actor-critic-based multi-agent framework that integrates tool grounding with dual-memory mechanisms for step-wise, reasoning-aware decision making, and uses stored actor-critic simulation trajectories for distillation. Experiments show that our dataset and framework improve multilingual medical reasoning accuracy across all Indic languages, with ablations validating the contribution of each component. The source code and dataset are available at: https://iitp-cse.github.io/ ArogyaSutra/

LabVLA: Grounding Vision-Language-Action Models in Scientific Laboratories

LabVLA:将视觉-语言-动作模型应用于科学实验室

Abstract
Scientific laboratories increasingly rely on AI systems to reason about experiments, but the physical act of doing science remains largely outside their reach. AI can help read literature, generate hypotheses, and plan protocols, yet the execution of those protocols at the bench still requires a human operator. Vision-Language-Action (VLA) models provide one possible interface between written protocols and robot execution, but existing policies are trained mostly on household and tabletop demonstrations and rarely encounter the instruments, transparent liquids, or fixed protocol workflows found in scientific laboratories. Closing this gap requires both laboratory-specific supervision and a unified learning framework that can accommodate the diverse robot embodiments used to execute experimental protocols. We therefore identify data and embodiment as central bottlenecks alongside model design. To address the data side, we build RoboGenesis, a simulation-based workflow and data engine that composes configured laboratory workflows from atomic skills, validates and filters rollouts, and exports structured demonstrations across supported robot profiles. On the policy side, we present LabVLA, trained with a two-stage recipe: FAST action token pretraining first makes the Qwen3-VL-4B-Instruct backbone action aware before any continuous control is learned, and flow matching posttraining then attaches a DiT action expert under knowledge insulation. On the LabUtopia benchmark, LabVLA achieves the highest average success rate among all evaluated baselines under both in-distribution and out-of-distribution settings.

One Polluted Page Is Enough: Evaluating Web Content Pollution in Generative Recommenders

一页污染内容足矣:评估生成推荐系统中的网络内容污染
Luo, Minghao, Chen, Liang
Abstract
Search-augmented LLMs increasingly mediate everyday consumer recommendations by retrieving live web content. This creates a new risk: generative recommenders may consume polluted web content, such as fake reviews and promotional pages crafted to mislead recommendations. We ask: to what extent do search-augmented LLMs become unwitting promoters of fake products when consuming polluted retrieval results? To answer this, we introduce FORGE (Fake Online Recommendations in Generative Environments), a benchmark for measuring fake-product promotion under controlled web-content pollution. Given an upstream search result, FORGE locally rewrites real products in retrieved web pages into fake ones to simulate web-content pollution, and measures how often the LLM recommends the fake product. FORGE covers 225 real-world products across 15 categories and 5 consumer scenarios. Across 12 commercial and open-weights LLMs, all models are vulnerable: a single polluted page yields fooled rates of up to 27%, while the full top-3 replacement raises this to 73.8%. Vulnerability varies substantially across categories, increasing when models lack stable prior knowledge of the relevant products. Reasoning does not mitigate this vulnerability; instead, it often generates spurious social proof to justify false recommendations. We evaluate three defenses: skepticism prompting and consensus filtering (over model priors or cross-document evidence). Skepticism can exacerbate vulnerability, much like reasoning, while filtering risks suppressing legitimate products. We release FORGE at https://github.com/leoluolol/forge-benchmark.

Beyond Uniform Tokens: Adaptive Compression for Time Series Language Models

超越统一令牌:时间序列语言模型的自适应压缩
Gan, Jialin, Qiu, Xin, Chen, Guangzhe, Wang, Xue
Abstract
Large language models (LLMs) have enabled time series (TS) analysis by jointly modeling numerical observations and textual context through a shared token interface. However, TS tokens and prompt tokens exhibit fundamentally different information structures, making uniform token processing inefficient. In this paper, we study token efficiency in TS language modeling from an asymmetric-token perspective. We show that TS tokens have highly uneven spectral contributions, where many tokens share redundant frequency patterns while a small subset preserves critical temporal evidence. We also observe that prompt-token influence attenuates with model depth, suggesting that full prompt retention across all layers is unnecessary. Based on these findings, we develop an adaptive token budgeting framework that compresses TS tokens via frequency-domain structure and progressively reduces prompt tokens across layers. Experiments across forecasting, classification, imputation, and anomaly detection demonstrate up to \textit{\textbf{7.68$\times$}} inference acceleration and performance gains in \textit{\textbf{78\%}} of evaluated settings, showing the effectiveness of asymmetric token compression for scalable TS foundation models.

From Tokens to Faces: Investigating Discrete Speech Representations for 3D Facial Animation

从音素到面孔:研究用于3D面部动画的离散语音表示
Correa, Pedro, Perrotin, Olivier, Sadok, Samir, Costa, Paula, Hueber, Thomas
Abstract
The choice of speech representation is critical in speech-driven 3D facial animation. Representations differ in what they encode: SSL features emphasize segmental and semantic cues, neural codecs yield latents optimized for acoustic reconstruction, and ASR-style objectives produce label-based spaces. We evaluate four speech representation families for 3D facial synthesis, comparing their facial reconstruction quality across two facial decoders using objective metrics and a perceptual evaluation. We additionally conduct probing analyses that relate tokenized representations to phonetic units and to articulatory deformations. We found that encoding phonetic classes is beneficial for accurate facial animation prediction on both semantic and label-based representations with comparable facial animation quality. From the latter, we introduce an Audio Visual Text-to-Speech (AVTTS) pipeline that leverages, as a shared space, discrete representations to decode speech and 3D facial motion.

语音表示的选择在基于语音的3D面部动画中至关重要。不同的表示在编码内容上存在差异:自监督学习(SSL)特征强调段落和语义线索,神经编解码器生成针对声学重建优化的潜在向量,而自动语音识别(ASR)风格的目标则产生基于标签的空间。我们评估了四种语音表示家族在3D面部合成中的表现,比较了它们在两个面部解码器上的面部重建质量,使用了客观指标和感知评估。此外,我们还进行了探测分析,将离散表示与语音单位和发音变形相关联。我们发现,编码语音类别对于在语义和基于标签的表示上准确预测面部动画是有益的,并且面部动画质量相当。基于后者,我们引入了一种音频视觉文本到语音(Audio Visual Text-to-Speech, AVTTS)管道,利用离散表示作为共享空间来解码语音和3D面部运动。

Operads for compositional reasoning in LLMs

用于大规模语言模型组合推理的算子
Bottman, Nathaniel, Richardson, Kyle
Abstract
Question decomposition, i.e. breaking a complex query into simpler sub-queries whose answers are composed to produce a final answer, is a widely used strategy for improving LLM reasoning, yet it currently lacks a rigorous mathematical foundation. In this paper, we propose operads, mathematical structures that model many-in, one-out operations and compositions thereof, as a natural framework for describing question decomposition. We define the questions operad $Q$, in which operations correspond to question templates and composition corresponds to substitution of sub-answers, and show how QA models can be interpreted as algebras over $Q$. Beyond reframing existing practice, this operadic perspective points toward new methods, in particular a notion of operadic consistency, which measures whether a QA model's answers agree across the partial collapses of a question decomposition tree. Empirical evaluation of operadic consistency is reported in our companion paper (Bottman, Liu, and Richardson, 2026), which finds it strongly correlated with accuracy across twelve LLMs and four multi-hop QA datasets and outperforming standard temperature-based self-consistency baselines. We argue that operads are the natural mathematical home for question decomposition, and that invariants such as operadic consistency open new directions for analyzing and improving the reliability of multi-step reasoning.

Recursive Agent Harnesses

递归代理工具
Lumer, Elias, Sen, Sahil, Paul, Kevin, Subbiah, Vamse Kumar
Abstract
Recursive language models (RLMs) showed that recursion over model calls is an effective strategy for long-context reasoning, and production coding agents have begun to write code that spawns subagents at scale, most recently in Anthropic's dynamic workflows. We name and study the pattern between these two lines of work, where the recursive unit is a full agent harness with filesystem tools, code execution, and planning rather than a model call with no tools. We call this the Recursive Agent Harness (RAH) and frame it as harness recursion, the code-first extension to the model recursion of RLMs. A parent agent generates and runs an executable script that spawns subagent harnesses in parallel for fine-grained workloads and uses structured function calls for small subtasks. We provide a controlled evaluation on long-context reasoning. With the backbone held fixed at GPT-5 to match the published Codex and RLM baselines, RAH improves the Codex coding-agent baseline from 71.75% to 81.36% on Oolong-Synthetic (199 samples, 13 context-length buckets up to 4M tokens), a gain attributable to the harness rather than the model. With a stronger backbone, Claude Sonnet 4.5, the same design reaches 89.77%.

SkMTEB:斯洛伐克大规模文本嵌入基准与模型适应

Abstract
We introduce SkMTEB, the first comprehensive MTEB-style text embedding benchmark for Slovak, a low-resource West Slavic language, comprising 31 datasets across 7 task types -- nearly 4$\times$ the depth of existing multilingual benchmark coverage for Slovak. Our evaluation of 31 embedding models reveals that large instruction-tuned multilingual models achieve the strongest performance, while existing Slovak-specific models trained for NLU tasks transfer poorly to embedding tasks. To address the need for efficient, locally-deployable Slovak embeddings, we develop \texttt{e5-sk-small} (45M parameters) and \texttt{e5-sk-large} (365M) by applying vocabulary trimming and fine-tuning to Multilingual E5 models. Despite size reductions of up to 62\%, our open-source models achieve competitive performance with proprietary APIs while remaining locally deployable for semantic search and retrieval-augmented generation (RAG). We release the benchmark, models, datasets, and code openly, hoping our approach offers a replicable path for other under-resourced languages.

Operadic consistency: a label-free signal for compositional reasoning failures in LLMs

算子一致性:一种无标签信号,用于检测大语言模型中的组合推理失败
Bottman, Nathaniel, Liu, Yinhong, Richardson, Kyle
Abstract
Detecting LLM reasoning failures at inference time without ground-truth labels has motivated a wide range of confidence baselines, including self-consistency, semantic entropy, and P(True), built on within-question sampling and self-evaluation. Operad theory, the formalism for systems built by iterated substitution, suggests a complementary diagnostic: a model's direct answer to a compositional query should agree with the answer it produces by composing a stated decomposition of the same query. We instantiate this idea as operadic consistency (OC), a per-question signal. Across twelve instruction-tuned LLMs (4B to 671B parameters, open-weights and closed-source) on four multi-hop QA datasets, OC is strongly correlated with accuracy on every dataset (Pearson $r \in [0.86, 0.94]$, all $p \leq 0.0004$), and is the only signal we evaluate with $r \geq 0.85$ uniformly across all four datasets. Chain-of-thought self-consistency (CoT-SC; Wang et al., 2023) matches OC on HotpotQA and DROP ($r = 0.93, 0.87$) but drops to $r \approx 0.45$ on MuSiQue and StrategyQA. At the per-question level, OC contributes information beyond CoT-SC and semantic entropy on every dataset (cluster-robust $p \leq 10^{-16}$ for the OC coefficient), and the conclusion is robust to additionally controlling for constructed decomposition-aware baselines ($p \leq 10^{-13}$). The same signal yields selective-prediction improvements (accuracy at fixed coverage) over a tuned CoT-SC baseline at the equal-cost $K = 3$ budget (AUARC lifts of +0.086 to +0.096 and AUROC lifts of +0.092 to +0.164; 95% CIs exclude zero on every cell). On five frontier thinking models, where the decomposition is extracted from the model's own chain of thought, the same equal-cost comparison gives positive selective-prediction point-estimate lift on all 16 (dataset, budget, metric) cells tested, with 95% CIs excluding zero on 12 of the 16.

This creates an \emph{execution-granularity mismatch}: locally deterministic tool workflows are unfolded into repeated model-visible decisions, consuming context and forcing the model to manage low-level dataflow in the trace. We introduce \textbf{HyperTool}, a unified executable MCP-style tool interface that changes the model-visible unit of tool execution. A model invokes HyperTool with a code block that can call existing tools through their original schemas, manipulate returned values, and pass intermediate results locally, folding deterministic tool subroutines into a single outer call. To train models to use this interface, we synthesize HyperTool-format trajectories from cross-tool compositional tasks and verify them in real MCP environments. On MCP-Universe, HyperTool improves average accuracy from 15.69\% to 35.29\% on Qwen3-32B and from 9.93\% to 33.33\% on Qwen3-8B, and surpass GPT-OSS and Kimi-k2.5 on average accuracy, showing that our HyperTool can substantially improve multi-step tool use.

工具增强的大型语言模型(LLM)代理通常依赖于逐步的原子工具调用,其中每次调用、观察和数值传递都在主要推理轨迹中显现。这导致了一个 extit{执行粒度不匹配}的问题:局部确定性的工具工作流被展开为重复的模型可见决策,消耗上下文并迫使模型在轨迹中管理低级数据流。我们提出了 extbf{HyperTool},一个统一的可执行MCP风格工具接口,改变了工具执行的模型可见单元。模型通过一个代码块调用HyperTool,该代码块可以通过其原始模式调用现有工具,操纵返回值,并在本地传递中间结果,将确定性的工具子例程折叠为一个外部调用。为了训练模型使用该接口,我们从跨工具组合任务中合成HyperTool格式的轨迹,并在真实的MCP环境中验证它们。在MCP-Universe上,HyperTool将Qwen3-32B的平均准确率从15.69\%提高到35.29\%,将Qwen3-8B的平均准确率从9.93\%提高到33.33\%,并在平均准确率上超越了GPT-OSS和Kimi-k2.5,显示出我们的HyperTool可以显著改善多步骤工具的使用。

Influcoder: Distilling Decoders' Gradient Influence Rankings into an Encoder for Data Attribution

Influcoder:将解码器的梯度影响排名提炼到编码器中以实现数据归因
Kachler, Dimitri, Sileo, Damien, Denis, Pascal
Abstract
With the growth of LLMs' (Large Language Models) capabilities, there has been an increasing push to curate high quality datasets by filtering samples in the training data. In general, Data Attribution (DA) methods aim to estimate how individual samples in a training dataset can precondition a model to generate certain outputs. As an example, one might be interested in which samples in the data could be the source of toxic behavior after training the LLM. Many methods quantify this conditioning through the paradigm of influence functions. While methods of this family are effective in its function, they lack the necessary processing speed and storage compactness to be practically implemented on large datasets. We propose a method, Influcoder, as a quick and cost-effective approach to influence-based Data Attribution at scale.

随着大型语言模型(LLMs)能力的增长,越来越多的努力致力于通过过滤训练数据中的样本来策划高质量的数据集。一般来说,数据归因(Data Attribution, DA)方法旨在估计训练数据集中个别样本如何影响模型生成特定输出。例如,人们可能会关注在训练LLM后,哪些样本可能是有毒行为的来源。许多方法通过影响函数的范式量化这种影响。尽管这一系列方法在其功能上是有效的,但它们缺乏必要的处理速度和存储紧凑性,无法在大规模数据集上实际应用。我们提出了一种方法,Influcoder,作为一种快速且具有成本效益的影响基础数据归因方法,适用于大规模数据集。

Learning to Reason by Analogy via Retrieval-Augmented Reinforcement Fine-Tuning

通过检索增强的强化微调学习类比推理
Xiao, Zilin, Ma, Qi, Chen, Chun-cheng Jason, Chen, Xintao, Atreya, Avinash, Chen, Hanjie, Ordonez, Vicente
Abstract
Retrieval-augmented generation (RAG) has become a standard mechanism for grounding language models in external knowledge, yet conventional retrieval based on lexical or semantic similarity is poorly suited for complex reasoning tasks: a semantically similar problem may demand an entirely different solution strategy, while a superficially different problem may share the same underlying reasoning pattern. We propose Retrieval-Augmented Reinforcement Fine-Tuning (RA-RFT), a post-training framework that teaches language models to reason by analogy. RA-RFT uses gold-relevance distillation to train a retriever that ranks contexts by expected reasoning benefit rather than semantic overlap, and then fine-tunes the policy model via reinforcement fine-tuning methods with retrieved analogous demonstrations, so the model learns to leverage reasoning traces under verifiable outcome rewards. We further analyze the diversity of retrieved contexts and find that reasoning-aware retrieval surfaces complementary solution strategies that provide distinct reasoning scaffolds for individual problems. Across challenging mathematical reasoning benchmarks, RA-RFT consistently outperforms standard reinforcement fine-tuning methods. For example, it improves AIME 2025 average@32 accuracy by 7.1 and 2.8 points over GRPO for Qwen3-1.7B and Qwen3-4B respectively -- suggesting that reasoning-aware retrieval is a complementary axis of improvement and orthogonal to advances in reward design or training curricula.

检索增强生成(RAG)已成为将语言模型与外部知识结合的标准机制,但基于词汇或语义相似性的传统检索方法不适合复杂推理任务:一个语义上相似的问题可能需要完全不同的解决策略,而一个表面上不同的问题可能共享相同的基本推理模式。我们提出了检索增强强化微调(RA-RFT),这是一种后训练框架,旨在教会语言模型通过类比进行推理。RA-RFT利用黄金相关性蒸馏训练一个检索器,该检索器根据预期推理收益而非语义重叠对上下文进行排名,然后通过强化微调方法利用检索到的类比示例微调策略模型,使模型能够在可验证的结果奖励下学习利用推理轨迹。我们进一步分析了检索上下文的多样性,发现关注推理的检索能够呈现互补的解决策略,为个别问题提供不同的推理支架。在具有挑战性的数学推理基准测试中,RA-RFT始终优于标准的强化微调方法。例如,它在AIME 2025 average@32的准确率上分别比GRPO提高了7.1和2.8个百分点,适用于Qwen3-1.7B和Qwen3-4B,这表明关注推理的检索是一个互补的改进方向,与奖励设计或训练课程的进展是正交的。

EvoArena: Tracking Memory Evolution for Robust LLM Agents in Dynamic Environments

EvoArena:在动态环境中跟踪记忆演变以增强大型语言模型代理的鲁棒性
Xu, Jundong, Li, Qingchuan, Wu, Jiaying, Lan, Yihuai, Li, Shuyue Stella, Zhou, Huichi, Jiang, Bowen, Wang, Lei, Wang, Jun, Luu, Anh Tuan, Xiong, Caiming, Park, Hae Won, Hooi, Bryan, Hu, Zhiyuan
Abstract
Large language model (LLM) agents have achieved strong performance on a wide range of benchmarks, yet most evaluations assume static environments. In contrast, real-world deployment is inherently dynamic, requiring agents to continually align their knowledge, skills, and behavior with changing environments and updated task conditions. To address this gap, we introduce EvoArena, a benchmark suite that models environment changes as sequences of progressive updates across terminal, software, and social domains. We further propose EvoMem, a patch-based memory paradigm that records memory evolution as structured update histories, enabling agents to reason about environmental evolution through changes in their memory. Experiments show that current agents struggle on EvoArena, achieving an average accuracy of 39.6% across evolving terminal, software, and social-preference domains. EvoMem consistently improves performance, yielding an average gain of 1.5% on EvoArena and also improving standard benchmarks such as GAIA and LoCoMo by 6.1% and 4.8%. Beyond individual tasks, EvoMem further improves chain-level accuracy by 3.7% on EvoArena, where success requires completing a consecutive sequence of related evolutionary subtasks. Mechanistic analysis shows that EvoMem improves evidence capture in the memory, indicating better preservation of complete evolving environment states. Our results highlight the importance of modeling evolution in both evaluation and memory for reliable agent deployment.

大型语言模型(LLM)代理在广泛的基准测试中取得了强劲的表现,但大多数评估假设环境是静态的。相比之下,现实世界的部署本质上是动态的,这要求代理不断调整其知识、技能和行为,以适应变化的环境和更新的任务条件。为了解决这一问题,我们引入了EvoArena,一个基准套件,将环境变化建模为终端、软件和社会领域的渐进更新序列。我们进一步提出了EvoMem,一种基于补丁的记忆范式,它将记忆演变记录为结构化的更新历史,使代理能够通过记忆中的变化推理环境的演变。实验表明,当前的代理在EvoArena上表现不佳,在不断变化的终端、软件和社会偏好领域的平均准确率仅为39.6%。EvoMem始终能提高性能,在EvoArena上平均提高1.5%的准确率,同时在GAIA和LoCoMo等标准基准上分别提高6.1%和4.8%。除了单个任务外,EvoMem还在EvoArena上将链级准确率提高了3.7%,成功完成需要连续完成一系列相关演变子任务的任务。机制分析表明,EvoMem改善了记忆中的证据捕获,表明对完整演变环境状态的更好保留。我们的结果强调了在评估和记忆中建模演变的重要性,以确保代理的可靠部署。
