From Absolute to Relative: Rethinking Reward Shaping in Group-Based Reinforcement Learning

ICML 2026poster

Reinforcement learning has become a cornerstone for enhancing the reasoning capabilities of Large Language Models, where group-based approaches such as GRPO have emerged as efficient paradigms that optimize policies by leveraging intra-group performance differences. However, these methods typically …

HandX: Scaling Bimanual Motion and Interaction Generation

CVPR 2026

Synthesizing human motion has advanced rapidly, yet realistic hand motion and bimanual interaction remain underexplored. Whole-body models often miss the fine-grained cues that drive dexterous behavior, finger articulation, contact timing, and inter-hand coordination, and existing resources lack hig

Unleashing Guidance Without Classifiers for Human-Object Interaction Animation

ICLR 2026poster

Generating realistic human-object interaction (HOI) animations remains challenging because it requires jointly modeling dynamic human actions and diverse object geometries. Prior diffusion-based approaches often rely on handcrafted contact priors or human-imposed kinematic constraints to improve con…

InterAct: Advancing Large-Scale Versatile 3D Human-Object Interaction Generation

CVPR 2025poster

While large-scale human motion capture datasets have advanced human motion generation, modeling and generating dynamic 3D human-object interactions (HOIs) remain challenging due to dataset limitations. Existing datasets often lack extensive, high-quality motion and annotation and exhibit artifacts s…
