Cet exposé est une session de rattrapage de la journée de rentrée.
Je présenterai les différents sujets sur lesquels je travaille, en particulier
les systèmes de particules en interaction avec contraintes cinétiques et les
marches aléatoires en milieu aléatoire dynamique.

K-means is a very well-known and widely used algorithm for clustering Euclidean data. It can be generalized to metric measure spaces, however, it is less well understood in settings where both the distance and the measure are unknown and must be estimated. In this talk, I will present recent work in which we prove the consistency of k-means in this context by establishing the stability of
k-means centroids and clusters with respect to the measured Gromov–Hausdorff topology. This framework provides a unified approach for proving consistency
across a wide range of metric learning procedures. In particular, I will discuss consequences for Isomap and Fermat geodesic distances on manifolds, diffusion distances, and Wasserstein distances.
Work in collaboration with P. Groisman (Buenos Aires), M. Jonckheere
(Toulouse) and M. Sued (Buenos Aires).
