タイトル Title

Finding Wasserstein saddle points “without” optimal transport

概要 Abstract

In this talk, we will discuss the problem of finding saddle points of a dynamical system in the Wasserstein space. We will recall existing approaches and present a new numerical scheme to approximate said saddle points. Our approach is based on known string method techniques for Hilbert spaces and is derived from a formal JKO (minimising movement) scheme. However, unlike geodesic approaches, ours does not require solving any optimal transport problems. We will showcase the performance of the method and validate it over several examples. This is ongoing work in collaboration with Jeroen Wapstra (TU Eindhoven).
