Designing Explicit Regularizers for Deep Models【IIIS-Haihua Frontier Seminar Series】

Speaker: Tengyu Ma Stanford University
Time: 2019-12-20 14:00-2019-12-20 15:00
Venue: FIT 1-315


I will discuss some recent results on designing explicit regularizers to improve the generalization performances of deep neural networks. We derive data-dependent generalization bounds for deep neural networks. We empirically regularize the bounds and obtain improved generalization performance (in terms of the standard accuracy or the robust accuracy), especially when we lack other sources of regularization, such as implicit/algorithmic regularization, data augmentation, etc. I will also touch on recent results on applying these techniques to imbalanced datasets. Based on joint work with Colin Wei, Kaidi Cao, Adrien Gaidon, and Nikos Arechiga.
