Xin-Qiang Cai @ MSLAB, UTokyo
Biography
Currently I am a second year Ph.D. student of Department of Complexity Science and Engineering in The University of Tokyo and a member of Sugiyama-Yokoya-Ishida Lab. Also, I am working as a research assistant on Beyond AI Institution.
I got my M.Sc. degree in Computer Science and Technology in June 2021 from Nanjing University as a member of LAMDA Group, supervised by professor Zhi-Hua
Zhou and professor Yuan Jiang.
I got my B.Sc. degree in Aircraft Design and Engineering in June 2018 from Northwestern Polytechnical University. In the same year, I was admitted to study for a M.Sc degree in Nanjing University without entrance examination.
Research Interests
Currently I am focusing on the subfields:
- Class Incremental Learning: classification problems with emerging new classes;
- Reinforcement Learning & Imitation Learning: learning a sequential-decision-making agent from the environment and/or demonstrations;
- Learning with Weak Supervision: learning a model from noisy, limited, or imprecise sources.
