These seminars are held on Thursday at 11 AM, at ENS, 29 rue d'Ulm, 75005 Paris.
Salle Langevin (1st floor of 29 rue d’Ulm, left corridor, just before the library)

The first seminar by Samantha Fournier is entitled "Learning with high-dimensional chaotic systems"
Chaotic dynamics can naturally arise in high-dimensional heterogeneous systems of interacting variables, of which a simple example are random Recurrent Neural Networks (RNNs). I will present a simple model for random RNNs which, in some instances of the model, is exactly solvable with Dynamical Mean-Field Theory (DMFT). Even though it is more abstract, I will show that the simple model has the same phenomenology as more standard models.
