Title: Understanding Adversarial Training via Model Calibration

Deep models have shown remarkable success in computer vision tasks, but they appear to be vulnerable to small, imperceptible changes over test instances. In this talk, I will provide a brief overview of our recent work in understanding adversarial training. Firstly, I will evaluate the defense performances of several model calibration methods on various robust models. Secondly, I will discuss some intriguing findings about adversarial training that show its connection to robust overfitting. Next, I will present our work on designing a simple yet effective regularization technique. Finally, I will conclude my talk by sharing some insights into adversarial training.
