LeRF: Learning Reference Coordinate Frames for Perspective Taking Reasoning
Teaching vision-language models to reason from new viewpoints with explicit reference frames and reinforcement learning.
Bang Xiao 肖棒
I am a Computer Science undergraduate at Shanghai Jiao Tong University, and a member of the Zhiyuan Honors Program.
Currently, I am a research visitor at Rehg Lab, University of Illinois Urbana-Champaign, advised by James M. Rehg. I am seeking PhD opportunities for Fall 2027.
Previously, I was a research intern at Microsoft Research Asia with Shaohan Huang and Tengchao Lv.
My research interests lie in multimodal reasoning, agents, and reinforcement learning. I focus on building world representations for agents that support reasoning, prediction, and learning through interaction with the environment.
Selected research.
- Multimodal reasoning
- Agents
- Reinforcement learning
Code Aesthetics with Agentic Reward Feedback
Improving the visual quality and functionality of generated code through agentic reward feedback.
Efficient and Scalable Monocular Human-Object Interaction Motion Reconstruction
Reconstructing physically plausible human–object interactions from monocular videos at scale.
