How to construct a planar Brownian motion from simple path and loops
Isao Sauzedde (ENS Lyon)
During this talk, I will present a joint paper with N. Berestycki in which we introduce and study a map which takes as inputs a [...]

Ancestral lineages and uniform sampling in populations with density-dependent interactions
Madeleine KUBASH (Ecole Polytechnique)
Résumé : We study a density-dependent Markov jump process describing a population where each individual is characterized by a type, and reproduces at rates depending [...]

Mean-field analysis of the training dynamics of two-layer neural networks
Arnaud Descours (ISFA, Lyon)
Training neural networks via stochastic gradient descent (SGD) amounts to solving a complex, non-convex optimization problem. Inspired by statistical mechanics, the mean-field approach provides a [...]

The partition function of β-ensembles with complex potentials
Alex Little (ENS Lyon)
The asymptotic behaviour of the partition function is one of the central questions of statistical mechanics. In our work we consider this problem when the [...]
