Tengyang Xie

Hi! I'm a Ph.D. student in Computer Science at University of Illinois at Urbana-Champaign (UIUC), where I am fortunate to work with Nan Jiang. My research mainly focuses on interactive machine learning, such as reinforcement learning, contextual bandits, and causal inference. Currently, I am working on two "opposite" directions: batch RL (a.k.a. off-policy/offline RL) -- how to learn from the exploratory data solely, and exploration in RL -- how to explore the environment efficiently. I am also interested in unsupervised/self-supervised learning and the theory of deep neural networks.

Prior to UIUC, I received master degree in Computer Science from University of Massachusetts Amherst (transferred the PhD status to UIUC). Before that, I obtained bachelor's degree in Physics from University of Science and Technology of China (USTC). I have also spent time at Simons Institute, Amazon AI, Microsoft Research, and Google Research.
