I am currently a third-year M.Sc. student at University of Chinese Academy of Sciences (UCAS), and doing my research at Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences. My research interest mainly includes trustworthy AI, machine learning, especially domain generalization, and reinforcement learning. Currently, my main focus is on investigating the out-of-distribution (ood) detection. The goal of my work is to enable fine-grained ood detection. I think the key to this work is finding a suitable compression structure to represent the in-distribution data.
