Biography

I am a graduate student at Georgia Tech, working with Prof. Le Song and Prof. Jim Rehg. Previously, I received a M.S. from Peking University and a B.E. from South China University of Technology. I finished a great internship at Nvidia Research.

 

My research interest broadly lies in statistical learning, (deep) representation learning and their applications to computer vision. I extremely appreciate the beauty of "light-and-sweet" algorithms: (i) light: easy to implement in practice, (ii) sweet: having clear intuitions or non-trivial theoretical guarantees. I also have the great pleasure to work closely with Yandong Wen, Zhiding Yu, Bo Dai, Zhen Liu, Xingguo Li and Tuo Zhao.
