This talk discusses three aspects of deep learning from a statistical perspective: interpolation, optimality and sparsity. The first one attempts to interpret the double descent phenomenon by precisely characterizing a U-shaped curve within the “over-fitting regime,” while the second one focuses on the statistical optimality of neural network classification in a student-teacher framework. This talk is concluded by proposing sparsity induced training of neural network with statistical guarantee.
Cheng is a Professor of Statistics at Purdue University. He received his PhD in Statistics from University of Wisconsin-Madison in 2006. His research interests include Big Data and Deep Learning.
