I’m a first-year master student majored in Computer Science in Shanghai Jiao Tong University, under the supervision of Prof. Chihao Zhang. From September 2023 to December 2024, the range of my research interest most lies in multi-armed bandits (MAB) problem and online learning. And I have learnt some basic knowledge about high-dimensional probability and stochastic differential equation. I’m willing and have got fully prepared for the exploration of new areas.
