报告摘要：Despite the phenomenal empirical successes of deep learning in many application domains, its underlying mathematical mechanisms remain poorly understood. In particular, deep learning has exhibited a number of surprising generalization phenomena that are not captured by classical statistical learning theory. This talk will introduce some of the intriguing generalization phenomena observed in deep learning, including implicit regularization, benign overfitting, and grokking, as well as some recent progress on the theoretical characterizations of these phenomena.
