Chao Xu

Ph.D. Candidate (Year 3)

Short Bio

I am currently a third-year Ph.D. student at the Center for Vision, Cognition, Learning, and Autonomy (VCLA), University of California, Los Angeles (UCLA), advised by Prof. Song-Chun Zhu. I received dual bachelor degrees in Computer Engineering from University of Illinois at Urbana-Champaign and Zhejiang University.

My research interests lie in the fields of computer vision, robotics, and cognitive science, especially covering 3D deep learning, object understanding, and cognitive robotics. My ongoing work focuses on learning generalizable object affordance, a kind of dark matter in AI cognitive systems, by drawing inspiration from embodied cognition and human reasoning.

We present a new task of part-level affordance discovery (PartAfford): Given only the affordance labels per object, the machine is tasked to (i) decompose 3D shapes into parts and (ii) discover how each part of the object corresponds to a certain affordance category.
