About Me
I am a first year Ph.D. student of
Department of Complexity Science and Engineering in
the University of Tokyo and a member of
SYI Lab. I also work as a research assistant on
Beyond AI. Previously, I got my M.Sc. degree with the LAMDA Group,
Nanjing University in June 2021 under the supervision of
Prof. Zhi-Hua Zhou.
Research Interests
My research interests include Machine Learning and Data Mining. Currently, I am interested in
- Online Learning and Sequential Prediction
- Supervised Learning with Distribution Change
- Weakly Supervised Learning
