About me

I am a Ph.D. student at The Chinese University of Hong Kong, Shenzhen (CUHKSZ), advised by Prof. Zhi-Quan (Tom) Luo.

My research interests include reinforcement learning theory, algorithms, and applications.

I have worked/interned at Tencent, Nanjing University, Cardinal Operations, etc.

My curriculum vitae can be downloaded from here.

Feel free to contact me if you want to discuss some ideas.

Selected Work

*: indicating equal contribution or alphabetic ordering.

  • Theoretical Analysis of Offline Imitation With Supplementary Dataset
    Ziniu Li* , Tian Xu*, Yang Yu, Zhi-Quan Luo
    (This work explores the framework of transfer learning (or domain adaption) used in CV, NLP, and RL,
    in terms of data coverage, importance sampling (or re-weighting), and feature alignment,
    answering questions including what kind of source data is helpful? when can the importance sampling improve a lot?)

  • Rethinking ValueDice: Does It Really Improve Performance?
    Ziniu Li* , Tian Xu*, Yang Yu, Zhi-Quan Luo
    In Proceedings of the 10th International Conference on Learning Representations (ICLR) (Blog Track), 2022
    (This work presents the first reduction of offline AIL to BC through a new DP-based analysis,
    proving that AIL is no better than BC in the offline setting and verifying this by experiments)
