Biography

I am a graduate student at Georgia Tech, working with Prof. Le Song. I also collaborate with Prof. Jim Rehg. Previously, I received a M.S. from Peking University and a B.Eng with highest honors from South China University of Technology.

 

My research interest broadly lies in statistical machine 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. Besides my advisors, I was also very fortunate to work closely with some talented researchers: Yandong Wen, Zhiding Yu, Prof. Meng Yang, Bo Dai, and Prof. Yan-Ming Zhang.

 

News: I am working at Nvidia Research for this summer.
