Definition
The term, in context
AI-assisted draft · approved dataset
UMA, short for Universal Models for Atoms, is a machine-learning interatomic potential trained across many chemical systems and material classes at once, letting a single model predict atomic-scale forces and energies for molecules, catalysts, battery materials, and other systems without needing a separate model retrained for each one.
