Título: Optimal Transport and Generative Modeling
Resumen: After a brief introduction to computational OT, I will present in this talk a few recent works highlighting the interest of OT solvers in generative problems. I will start with a recent result on a factorization of probability measures that builds upon the idea of moment measures introduced by Cordero-Erausquin and Klartag in 2015. I will show how this idea can be modified to suit better the generative paradigm to present conjugate moment measures. Next, I will show how simple OT maps on activations can help control --- using very few intervention examples --- the generation of LLMs and text-2-image models. Finally, I will investigate to what extent the use of large coupling solvers can improve the training of flow matching models.
