Flow Annealed Importance Sampling Bootstrap

LI Midgley, V Stimper, GNC Simm, B Schölkopf, JM Hernández-Lobato

A method for training generative models on Boltzmann distributions using only molecular energy functions, without requiring samples from the target distribution. Enables accurate sampling of complex molecular systems.

SE(3) Equivariant Augmented Coupling Flows

LI Midgley, V Stimper, J Antorán, E Mathieu, B Schölkopf, JM Hernández-Lobato

An equivariant generative model for molecular conformations that respects the physical symmetries of 3D space. Achieves sampling more than an order of magnitude faster than traditional molecular dynamics.
