[Curriculum Vitae]      [Google Scholar]

I am an MPhil student in mathematics at The Hong Kong University of Science and Technology. Prior to this, I received a B.S. in mathematics from the University of Science and Technology of China in 2021.

Recent News

After two fabulous years working with my amazing advisor Prof. Tong Zhang, I am currently looking for a Ph.D. position in EECS/STAT.

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 research has mainly focused on the interactive decision-making problems, but I am also interested in the interplay between statistics and optimization in machine learning. I am particularly interested in a sound understanding of the practically powerful learning algorithms and their statistical limits.


  • 01/2023: One paper accepted to ICLR 2023.

  • 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 received 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

5 Note on reduction-based RL

6 Note on non-linear contextual bandit
