Siyuan Huang

Seattle I am a fifth year Ph.D. student in the Department of Statistics at University of California, Los Angeles. I am currently doing computer vision research at the Center for Vision, Cognition, Learning, and Autonomy (VCLA) and am advised by Professor Song-Chun Zhu. During my Ph.D., I have interned at DeepMind and Facebook Reality Lab. Before coming to UCLA, I graduated from Tsinghua University with a Bachelors in Department of Automation.


My research interests lie in computer vision, machine learning, cognition, and robotics.
I currently focus on the problem of human-like holistic 3D scene understanding which contains perception, interaction, learning and reasoning.

  • Perception: Task-oriented 3D Scene Parsing & Reconstruction & Synthsis, Action Understanding
  • Interaction: 4D Human-object Interaction, Human-human Interaction
  • Learning: Neural-symbolic Learning, Structure Learning, Self-supervised Learning, Concept Learning
  • Reasoning: Vision-and-Language Reasoning, Cognitive Reasoning, Systematic Generalization
I would like to develop tools to help machines learn 3D representations, percept 3D world, and interact with 3D environments from images or videos. My long-term goal is to build a general-purpose intelligent machine that could understand and interact with the 3D environment like humans.
