I am a PhD student of Department of Computer Science & Technology in Nanjing University and a member of LAMDA Group, which is lead by professor Zhi-Hua Zhou. My supervisor is Yu-Feng Li. Before that, I received my B.Sc. degree from Software College of Jilin University.

Research Interests

I am engaged in machine learning research.
I have strong interests in weakly supervised learning (Incomplete/Inaccurate/Inexact Supervised Learning)and efficient optimization algorithm.
My current foucues are
