Optimal Transport @ Inria Saclay
ParMA is a research team at the Inria Saclay Centre, in partnership with CNRS and Université Paris-Saclay. We study optimal transport and its applications, with a particular focus on particle methods. Our research focuses on the application of OT techniques to the numerical resolution of problems, where one want to impose that a point cloud (representing either some data, or the result of a simulation) follows a certain probability distribution. This will for instance be done by using the Wasserstein distance as a penalization. We especially focus on the numerical analysis and resolution relying on particle discretization (i.e. point clouds).
