E(3)-Equivariant Graph Neural Networks for Data-Efficient and Accurate Interatomic Potentials

1 code implementation8 Jan 2021 Simon Batzner, Albert Musaelian, Lixin Sun, Mario Geiger, Jonathan P. Mailoa, Mordechai Kornbluth, Nicola Molinari, Tess E. Smidt, Boris Kozinsky

This work presents Neural Equivariant Interatomic Potentials (NequIP), an E(3)-equivariant neural network approach for learning interatomic potentials from ab-initio calculations for molecular dynamics simulations.

Multitask machine learning of collective variables for enhanced sampling of rare events

no code implementations7 Dec 2020 Lixin Sun, Jonathan Vandermause, Simon Batzner, Yu Xie, David Clark, Wei Chen, Boris Kozinsky

Computing accurate reaction rates is a central challenge in computational chemistry and biology because of the high cost of free energy estimation with unbiased molecular dynamics.

BIG-bench Machine Learning Dimensionality Reduction

Bayesian Force Fields from Active Learning for Simulation of Inter-Dimensional Transformation of Stanene

3 code implementations26 Aug 2020 Yu Xie, Jonathan Vandermause, Lixin Sun, Andrea Cepellotti, Boris Kozinsky

We present a way to dramatically accelerate Gaussian process models for interatomic force fields based on many-body kernels by mapping both forces and uncertainties onto functions of low-dimensional features.
