Title: Quantitative Uniform Stability of the Iterative Proportional Fitting Procedure

Abstract:  We establish the uniform in time stability, w.r.t. the marginals, of the Iterative Propor- tional Fitting Procedure, also known as Sinkhorn algorithm, used to solve entropy-regularised Optimal Transport problems. Our result is quantitative and stated in terms of the 1- Wasserstein metric. As a corollary we establish a quantitative stability result for Schrödinger bridges.

This is joint work with V. de Bortoli and A. Doucet.
