Giulia Luise - Imperial College

Abstract

The entropic regularization has proved to be a powerful tool to define approximations of optimal transport distances with improved computational and statistical aspects. In this talk we will focus on further advantages of such entropic regularization, in terms of smoothness. We discuss its regularity properties and their role in some machine learning problems where regularized optimal transport is used as discrepancy metric in supervised and unsupervised frameworks.
