Dual- versus Single-Suggestion AI Support for Radiographic Interpretation in Residents: Randomized Multireader Study

Lin Wu, Zhe Xu, Hongyi Wang وآخرون · 2026

Purpose: To compare dual- and single-suggestion AI support for radiographic interpretation by residents, particularly when the shared AI suggestion was incorrect. Materials and Methods: This prospective, multicenter, randomized three-arm reader study was conducted at three hospitals in China from July to September 2026 …

XTurnix: Large-Scale Self-Supervised Turn Control through Two-State Binary Decisions

Zhanxun Liu, Yifan Duan, Hengtao Wu وآخرون · 2026

General turn-taking behavior in real-time dialogue systems requires deciding whether to keep listening or start responding while listening, and whether to continue or stop while speaking. Existing turn detectors use heterogeneous, task-specific label spaces and are often trained on limited annotations or evaluated on i …

SimpleTouch: Can Vision-Language-Action Models Master Contact-Rich Manipulation Without Tactile Policy Pretraining?

Chen Yang, Linzhe Shi, Changjie Wu وآخرون · 2026

Tactile sensing provides essential contact information for robotic manipulation, yet incorporating it into pretrained vision-language-action (VLA) models remains challenging. A common concern is that simply introducing touch during task-specific fine-tuning may fail to bridge the cross-modal gap, yielding limited gains …

Asking the World: Generalist Physical Reasoning through Agentic World Modeling and Probing

Shenxiang Zeng, Chen Yang, Peiyao Chen وآخرون · 2026

Physical reasoning from video requires inferring latent physical properties and dynamics beyond direct observation. Direct VLM inference remains unreliable on complex physical tasks without explicit modeling and validation, while predefined tool pipelines rely on task- and domain-specific priors that limit generalizati …

Learning Expressive and Compositional Motion Representation via Spectral Skills

Feiyang Wu, Chenxiao Gao, Chen Yang وآخرون · 2026

Robotic foundation models offer a promising path toward general-purpose humanoid robot control, often through hierarchical architectures. However, their effectiveness depends on the command interface between the planner and the controller, which must support accurate execution while remaining easy to predict, and ideal …

Rethinking Circuit Evaluation: Do Circuits Explain Model Errors?

Li Zhang, Chuqin Geng, Mark Zhang وآخرون · 2026

Mechanistic interpretability (MI) aims to explain a model's behaviour through analyzing its internal computations; circuit-based explanations aim to isolate these computations with compact subnetworks validated by ablating the rest of the model. We show that circuits validated this way may fail to recover the underlyin …

Atomic Motion Coordinate for Language-Steerable and Force-Responsive Manipulation

Jiaqi Zhai, Jingkai Zhao, Chen Yang وآخرون · 2026

Can changing only the language instruction redirect a VLA policy's end effector, or does the visually driven motion prior dominate? We present Atomic Motion Coordinate, a geometry-grounded coordinate for steerable and force-responsive manipulation. Each arm owns thirteen signed translation, rotation, and hold atoms gro …

Distributional sentiment modeling and anomaly detection for consumer complaint assessment

Sentiment analysis is a common tool for converting unstructured text into quantitative signals in finance and risk management. Yet most applications reduce the output to a discrete polarity label or a single predictive feature, overlooking the distributional structure of sentiment intensity in consumer complaint narrat …
