About me

Hi! I am Zichuan Lin. I am a researcher working on game AI at Tencent AI Lab. I got my Ph.D. degree in June, 2021 in the Department of Computer Science and Technology, Tsinghua University, advised by Prof. Guangwen Yang. Previously, I completed my B.S. in Computer Science at Tsinghua University.

I was a research intern at Microsoft Research Asia (MSRA) from Sep, 2016 to Mar, 2018 (advised by Lintao Zhang) and from May, 2018 to Jun, 2019 (advised by Tao Qin and Li Zhao). I was a visiting student researcher at Stanford University from Feb, 2020, advised by Prof. Tengyu Ma.

My research interests include reinforcement learning and deep learning. My goal is to develop sample-efficient reinforcement learning algorithms with strong robustness and interpretability. My research projects mainly involve episodic control, reward decomposition, disentangled representation learning, model-based RL and meta-RL. I am also interested in RL applications such as task-oriented dialogue systems.
