Generative methods for sampling transition paths in molecular dynamics

no code implementations5 May 2022 Tony Lelièvre, Geneviève Robin, Inass Sekkat, Gabriel Stoltz, Gabriel Victorino Cardoso

Molecular systems often remain trapped for long times around some local minimum of the potential energy function, before switching to another one -- a behavior known as metastability.

Quantifying the mini-batching error in Bayesian inference for Adaptive Langevin dynamics

no code implementations21 May 2021 Inass Sekkat, Gabriel Stoltz

Bayesian inference allows to obtain useful information on the parameters of models, either in computational statistics or more recently in the context of Bayesian Neural Networks.

Chasing Collective Variables using Autoencoders and biased trajectories

no code implementations22 Apr 2021 Zineb Belkacemi, Paraskevi Gkeka, Tony Lelièvre, Gabriel Stoltz

In this context, approaches where the CVs are learned in an iterative way using adaptive biasing have been proposed: at each iteration, the learned CV is used to perform free energy adaptive biasing to generate new data and learn a new CV.

Hybrid Monte Carlo methods for sampling probability measures on submanifolds

no code implementations6 Jul 2018 Tony Lelièvre, Mathias Rousset, Gabriel Stoltz

In order to avoid biases in the invariant probability measures sampled by discretizations of these stochastically perturbed Hamiltonian dynamics, a Metropolis rejection procedure can be considered.

Robust determination of maximally-localized Wannier functions

1 code implementation23 May 2016 Éric Cancès, Antoine Levitt, Gianluca Panati, Gabriel Stoltz

We propose an algorithm to determine Maximally Localized Wannier Functions (MLWFs).
