With slight changes of the initialization and hyperparameters, we achieve improved RMSE on the 3BPA test set! This work serves as a simple introduction to training and testing equivariant neural network potentials in JAX, and can be easily extended for new methodologies.

In order to verify correctness of the implementation, we compare performance on the 3BPA dataset to two different PyTorch NequIP implementations: (1) @simonbatzner.bsky.social
et al.'s "nequip" repo, and (2) @ilyesbatatia.bsky.social
et al.'s "mace" repo...

The package includes code for training and evaluation of neural network potentials, a calculator for usage with Atomic Simulation Environment (ASE), and pre-trained weights for the 3BPA dataset.

The goal of the repository is to offer a simple (<1000 lines of code) implementation while providing competitive performance to existing codebases.
