Bézout Colloquium June 13, 2025 in Université Gustave Eiffel Copernic building room 4B125 4th floor
14:00 – Professor Gilles Mordant is a postdoctoral researcher in A. Munk’s group in Göttingen, working on statistical applications of optimal transport to biophysics data. Professor Gilles Mordant is hosted by Théo Lacombe and François-Xavier Vialard of LIGM laboratory, Université Gustave Eiffel.
Title: Optimal transport with small entropic regularisation by Gilles Mordant
Abstract: In this talk, we will describe what happens for entropy-regularised optimal transport with a small regularisation parameter.
We will discuss how to choose the regularisation parameter in a statistical context where one has access to sample points instead of the true measure and describe the fluctuations of the objects under consideration. We will further discuss the usefulness of small regularisation for deterministic particle flows as well as the theoretical questions that the latter raise.
16:00 – Coffee break
