Stopping and Routing LLM Judge Panels
Bin Zhu, Yi Xie, Yanghui Rao
LLM evaluation pipelines often have many candidate judges: general LLM-as-a-judge prompts, reward models, safety classifiers, confidence variants, and task-specific verifiers. The…
RoboTrustBench: Benchmarking the Trustworthiness of Video World Models for Robotic Manipulation
Huiqiong Li, Jiayu Wang, Zhiting Mei +3
Video world models are increasingly used in robotic manipulation, yet existing benchmarks mostly evaluate them under valid, feasible, and safe instructions. We introduce RoboTrustB…
A Finite-Calibration Regime Map for LLM Judge Panels
Bin Zhu, Yi Xie, Yanghui Rao
Deploying an LLM judge panel spends human labels on fitting a calibrator, constructing candidate judge paths, and validating which candidate to deploy. We study when finite labels…
-WM: A Unified Video-Action World Model for Robotic Manipulation
Pengfei Zhou, Shengcong Chen, Di Chen +17
Robotic manipulation requires models that generate executable actions while anticipating and evaluating their future consequences before physical execution. We present -World…
Beyond Task Success: Behavioral and Representational Diagnostics for WAM and VLA
Hung Mai, Bin Zhu, Tuan Do
Vision-language-action (VLA) policies and World-Action Models (WAM) represent two increasingly important paradigms for robotic manipulation. However, it remains unclear whether fut…
Teacher-Student Diffusion Model for Text-Driven 3D Hand Motion Generation
Ching-Lam Cheng, Bin Zhu, Shengfeng He
Generating realistic 3D hand motion from natural language is vital for VR, robotics, and human-computer interaction. Existing methods either focus on full-body motion, overlooking…
