Can Machine Learning Potentials Be More Accurate Than the Methods They Are Trained On?

Read the original on arXiv AI →

The article discusses how machine learning potentials (MLPs) can surpass the accuracy of the quantum‑chemical methods they are trained on by generalizing across a third space—different quantum‑chemical methods. It proposes the development of method‑transferable MLPs that predict properties at unseen methods, demonstrating that such models can outperform any of their training methods in both density‑functional and wavefunction‑based theories. The authors argue that pursuing accuracy beyond the training methods could enable universal MLPs to exceed single‑method models, influencing dataset construction and model evaluation to push chemical simulation limits.

Electron-Density-Informed Molecular Property Prediction Using Surrogate Functionals

The paper introduces a machine‑learning approach that incorporates the ground‑state electron density as input while enforcing it to be the minimum of a surrogate functional derived from orbital‑free density functional theory. This method outperforms state‑of‑the‑art models on six of seven extensive properties in the QM9 dataset and shows better generalization to larger molecules in the QM40 dataset. Models that use the density without enforcing the surrogate functional constraints perform worse on all extensive properties of both datasets.

BOOM: Benchmarking Out-Of-distribution Molecular Property Predictions of Machine Learning Models

BOOM is a new benchmark for evaluating out‑of‑distribution (OOD) molecular property predictions in machine learning. It provides chemically‑informed tests across common property prediction tasks and assesses over 150 model‑task combinations. The study shows that current models, including chemical foundation models, struggle to generalize OOD, with the best model still exhibiting three times higher error than in‑distribution predictions.
