Chong Chen (陈冲)’s Homepage

I am now a fourth year Ph.D. student in THUIR group, Department of Computer Science and Technology in Tsinghua University, Beijing, China. My supervisor is Prof. Min Zhang. I was a visiting student from April, 2019 to September, 2019 in The Web Intelligent Systems and Economics (WISE) Lab at Rutgers, advised by Prof. Yongfeng Zhang.

My research interests are deep learning, user modeling, recommendation and etc.

My research is supported by Baidu and ByteDance Scholarships.
