About me
Hi! I am a Ph.D. Candidate at the University of Pennsylvania and advised by Pratik Chaudhari. I work on a handbook for pre-training models. My research interests span areas like pre-training, transfer learning, unsupervised learning, generative models, and information theory. I graduated from Shanghai Jiao Tong University (SJTU) in 2017 with a Dual Degree (Bachelor in Mathematics and Physics), where Yaokun Wu advised me.
Research
My research interests include:
Multi-task Learning, Transfer Learning, and Unsupervised Learning
Deep Gnerative Models, Foundation Models
Information Geometry, Information Theory
Algorithmic game theory
