Research
My research interests lie in machine learning and deep learning. My long-term goal is to develop trustworthy intelligent systems, which can learn and reason from a massive volume of complex (e.g., weakly supervised, adversarial, causal, fair, and privacy-preserving) data (e.g, label, example, preference, domain, similarity, graph, and demonstration) automatically. Recently, I develop core machine learning methodology. Besides, I am actively applying our fundamental research into the healthcare domain (e.g., medical image understanding). I am heading Trustworthy Machine Learning Group.
My current research work center around four major themes (with representative works/projects; more information here):
Selected Projects
RGC ECS (PI): Trustworthy Deep Learning from Open-set Corrupted Data [Link] [Website]
NSFC YSF (PI): The Research on the Automated Trustworthy Machine Learning
