[Curriculum Vitae]      [Google Scholar]

I am a first-year Ph.D. student in mathematics at The Hong Kong University of Science and Technology, advised by Prof. Tong Zhang. I received a B.S. in mathematics from the University of Science and Technology of China in 2021, where I worked closely with Prof. Cong Shen and Prof. Haishan Ye.

My friend Weiyu Li has not updated her homepage since she moved to Harvard. Please feel free to send an email to push her.

Research Interests

My current research interests focus on learning theory.

I also spent a lot of time on matrix computation and optimization as an undergraduate student.


  • 05/2022: Two papers accepted to ICML 2022.

  • 04/2022: We are organizing reading courses in HKUST on learning theory and high-dimensional statistics.

    • Concentration inequality, metric entropy, covering number, empirical process, (local) Rademacher complexity, random vectors and matrices, Le Cam's method,

    • Stability analysis, kernel method, NTK, mean-field formulation, online learning,

    • These courses significantly enrich my toolbox and help me to tanxiaofengsheng with my advisor.

  • 03/2022: Two papers accepted to ICLR 2022 Workshop on Gamification and Multiagent Solutions.

  • 09/2021: Three papers accepted to Neurips 2021.

  • 09/2021: I started my PhD with the Hong Kong PhD Fellowship (HKPFS).


I often learn by copying books…

1 Note on exponential inequality

2 Note on metric entropy

3 An Alternative Analysis of High-Probability Generalization Bound for Uniformly Stable Algorithms

4 Note on minimax lower bound
