Greetings!
Hi, I'm Yichen Li, a Ph.D. candidate in Computer Science at the University of Arizona., advised by Chicheng Zhang .
My research focuses on Imitation Learning, and Reinforcement Learning.
I have interned at top organizations like Microsoft Research and Sanofi, and I enjoy solving fundamental problems in AI.
Internship Experiences
- Microsoft Research , Research Intern (Large Action Model), Apr - Jun 2024 - Developed offline imitation learning pipelines for simulator-based racing. - Designed and trained transformer-based models for state and action sequence prediction.
- Sanofi, Research Scientist Intern, May - Aug 2023 - Proposed dual-branch GANs for unpaired stain transfer, generating controllable virtual staining images. - Published work accepted at MICCAI-AMAI 2023.
