ACM@UIOWA: Tech Talk with Professor Tianbao Yang - Artificial Intelligence: Deep AUC Maximization

Friday, September 24, 2021, 5:00pm to 6:45pm
Seamans Center, 2229
103 South Capitol Street, Iowa City, IA 52240

Abstract:

In this talk, I will present our recent research on a new learning paradigm of deep learning by AUC maximization (including both AUROC and AUPRC). I will present a new surrogate loss for AUROC and non-convex min-max optimization algorithms for solving deep AUROC maximization problem.  Then, I will present our recent work on non-convex optimization algorithms for solving deep AUPRC maximization problem. I will also talk about their applications in medical image classification and molecular property prediction for drug discovery. In particular, our deep AUC maximization is currently ranked at the 1st place at Stanford CheXpert competition and also the 1st place at MIT AICURES challenge.
