I am a final-year Ph.D. candidate in Computer Science Department, UCLA, advised by Prof. Demetri Terzopoulos, Prof. Ying Nian Wu and Prof. Song-Chun Zhu. I did my undergrad at The Hong Kong University of Science and Technology (HKUST). I have conducted research at Google DeepMind, Google Brain, Meta Fundamental AI Research (FAIR), Amazon AWS AI, and SenseTime Research.

I am broadly interested in fundamental problems in Machine Learning and Artificial Intelligence, including Generative Modeling, Sequential Decision-Making, and Representation Learning, etc. Recently, I am exploring a Decision-Making perspective of Maximum Likelihood Estimate over Latent-Variable Sequence Models.

I started studying reinforcement learning long before my doctoral study and this was my first published work. The idea is to model a policy as a joint distribution of top-level latent variables for episodic consistency and bottom-level actions for instant behaviors, so as to form a hierarchy of temporal resolution. While this work seems naive in retrospect, the underlying quest is still driving me forward.
