On the Inclusion of Charge and Spin States in Cartesian Tensor Neural Network Potentials

no code implementations22 Mar 2024 Guillem Simeon, Antonio Mirarchi, Raul P. Pelaez, Raimondas Galvelis, Gianni de Fabritiis

In this letter, we present an extension to TensorNet, a state-of-the-art equivariant Cartesian tensor neural network potential, allowing it to handle charged molecules and spin states without architectural changes or increased costs.

TorchMD-Net 2.0: Fast Neural Network Potentials for Molecular Simulations

1 code implementation27 Feb 2024 Raul P. Pelaez, Guillem Simeon, Raimondas Galvelis, Antonio Mirarchi, Peter Eastman, Stefan Doerr, Philipp Thölke, Thomas E. Markland, Gianni de Fabritiis

Achieving a balance between computational speed, prediction accuracy, and universal applicability in molecular simulations has been a persistent challenge.

SPICE, A Dataset of Drug-like Molecules and Peptides for Training Machine Learning Potentials

no code implementations21 Sep 2022 Peter Eastman, Pavan Kumar Behara, David L. Dotson, Raimondas Galvelis, John E. Herr, Josh T. Horton, Yuezhi Mao, John D. Chodera, Benjamin P. Pritchard, Yuanqing Wang, Gianni de Fabritiis, Thomas E. Markland

Machine learning potentials are an important tool for molecular simulation, but their development is held back by a shortage of high quality datasets to train them on.

A Scalable Molecular Force Field Parameterization Method Based on Density Functional Theory and Quantum-Level Machine Learning

no code implementations16 Jul 2019 Raimondas Galvelis, Stefan Doerr, Joao M. Damas, Matt J. Harvey, Gianni de Fabritiis

We demonstrate that for the case of torchani-ANI-1x NNP, we can parameterize small molecules in a fraction of time compared with an equivalent parameterization using DFT QM calculations while producing more accurate parameters than FF (GAFF2).
