Researchers have developed a new method called PROBE to assess the reliability of machine-learned interatomic potentials (MLIPs). Unlike existing ensemble-based approaches that scale poorly, PROBE uses a compact classifier on frozen representations from a pretrained MLIP. This post-hoc technique generates a per-prediction reliability probability that accurately tracks actual error without altering the original model. PROBE also provides chemically interpretable per-atom importance maps as a byproduct. AI
