Minkai Xu「徐民凯」

I am a first-year research master student at Montreal Institute for Learning Algorithms (Mila). Before that, I received my bachelor degree from Shanghai Jiao Tong University (SJTU), advised by Prof. Yong Yu and Prof. Weinan Zhang.

During my undergraduate years, I visited Prof. Jian Tang's group at Mila in summer, 2019. Then I spent a wonderful year working with Dr. Lei Li, Dr. Mingxuan Wang and Dr. Hao Zhou at ByteDance (TikTok) AI Lab.

Research Topics

My research interests primarily lie in deep generative models. Based on the fundamental understanding, I’m also eager to do research with a strong societal impact. Currently, I concetrate on the generative tasks on discrete data, e.g., graph and text.
