When Vision Overrides Language: Evaluating and Mitigating Counterfactual Failures in VLAs

Yu Fang, Yuchun Feng, Dong Jing +5

The paper studies how Vision-Language-Action (VLA) models often ignore language instructions by relying on visual shortcuts, introduces a counterfactual benchmark (LIBERO-CF) to ev…

Learning Action Priors for Cross-embodiment Robot Manipulation

Dong Jing, Tianqi Zhang, Jiaqi Liu +5

Most Vision-Language-Action (VLA) models build on a Vision-Language Model (VLM) backbone by attaching an action module and optimizing the full policy jointly. This design inherits…

TempoVLA: Learning Speed-Controllable Vision-Language-Action Policies

Dong Jing, Jingchen Nie, Tianqi Zhang +4

Robot manipulation alternates between low-risk transit phases that call for fast execution and high-risk contact stages that demand slow, precise motion. Yet existing Vision-Langua…

AutoResearchClaw: Self-Reinforcing Autonomous Research with Human-AI Collaboration

Jiaqi Liu, Shi Qiu, Mairui Li +33

Automating scientific discovery requires more than generating papers from ideas. Real research is iterative: hypotheses are challenged from multiple perspectives, experiments fail…
