(09/03/2022) Carsten Hartmann: Coarse-graining of multiscale diffusions with parameter uncertainties

Abstract: Complex dynamical systems like molecular systems or stochastic climate models often involve a variety of different time and length scales. We propose a strategy for coarse graining of such…

(02/03/2022) Pierre Monmarché: Non-asymptotic convergence bounds for Hamiltonian Monte Carlo and Langevin diffusion in the convex case

Abstract: The Hamiltonian Monte Carlo and Langevin processes are kinetic (position/velocity) Markov processes used to sampled target distributions in MCMC methods. In fact, once discretized in time,…

(09/02/2022) Jonas Latz: Stochastic gradient descent in continuous time: discrete and continuous data

Abstract: Optimisation problems with discrete and continuous data appear in statistical estimation, machine learning, functional data science, robust optimal control, and variational inference. The…

(02/02/2022) Bernadette Stolz: Applications of global and local persistent homology for the shape of biological data

Abstract: In the first part of this talk, I will showcase how persistent homology can be used to spatially characterise structural abnormality in tumour blood vessel networks. More specifically, I…

(26/01/2022) Marie-Therese Wolfram: Inverse Optimal Transport

Abstract: In inverse optimal transport (IOT) one wishes to identify unknown cost criteria from noisy or partial observations of optimal matchings. Consider for example commodity data; assuming that…
