Flow Annealed Importance Sampling Bootstrap

3 code implementations3 Aug 2022 Laurence Illing Midgley, Vincent Stimper, Gregor N. C. Simm, Bernhard Schölkopf, José Miguel Hernández-Lobato

Normalizing flows are tractable density models that can approximate complicated target distributions, e. g. Boltzmann distributions of physical systems.

MACE: Higher Order Equivariant Message Passing Neural Networks for Fast and Accurate Force Fields

2 code implementations15 Jun 2022 Ilyes Batatia, Dávid Péter Kovács, Gregor N. C. Simm, Christoph Ortner, Gábor Csányi

In particular, we show that using four-body messages reduces the required number of message passing iterations to just two, resulting in a fast and highly parallelizable model, reaching or exceeding state-of-the-art accuracy on the rMD17, 3BPA, and AcAc benchmark tasks.

The Design Space of E(3)-Equivariant Atom-Centered Interatomic Potentials

2 code implementations13 May 2022 Ilyes Batatia, Simon Batzner, Dávid Péter Kovács, Albert Musaelian, Gregor N. C. Simm, Ralf Drautz, Christoph Ortner, Boris Kozinsky, Gábor Csányi

The rapid progress of machine learning interatomic potentials over the past couple of years produced a number of new architectures.

Bootstrap Your Flow

A Fresh Look at De Novo Molecular Design Benchmarks

no code implementations NeurIPS Workshop AI4Scien 2021 Austin Tripp, Gregor N. C. Simm, José Miguel Hernández-Lobato

De novo molecular design is a thriving research area in machine learning (ML) that lacks ubiquitous, high-quality, standardized benchmark tasks.

Symmetry-Aware Actor-Critic for 3D Molecular Design

1 code implementation ICLR 2021 Gregor N. C. Simm, Robert Pinsler, Gábor Csányi, José Miguel Hernández-Lobato

Automating molecular design using deep reinforcement learning (RL) has the potential to greatly accelerate the search for novel materials.
