Advisor: Prof. Ming Li

I am a Ph.D. candidate of Department of Computer Science and Technology in Nanjing University, and a member of LAMDA Group, led by Prof. Zhi-Hua Zhou. Before that, I received my B.Eng. degree in Computer Science and Technology in June 2016 from Xi’an Jiaotong University.

Research Interests. I am interested in topics of machine learning, especially the following aspects:

  • AUC Optimization: building models for maximizing AUC from clean or potentially noisy, imbalanced, not fully supervised data.
  • Weakly Supervised Learning: dealing with inaccurate, incomplete, inexact supervisions, including positive-unlabeled learning, semi-supervised learning, noisy label learning, etc.
  • Learning under Distribution Change: building models for tasks whose test data distribution is different from the training data distribution, including data selection bias, covariate shift, domain adaptation, etc.
