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.

ElemeNet: Multiscale Molecular Machine Learning with Uncertainty Quantification Across the Periodic Table

arXiv:2606. 30961v1 Announce Type: cross Abstract: Advances in deep learning architectures and representations have enabled ML-driven chemical property prediction, but state-of-the-art (SOTA) models have remained largely confined to independent codebases and lack support for diverse chemical species.

Benchmarking Compositional Generalisation for Machine Learning Interatomic Potentials

The paper introduces a benchmark to evaluate compositional generalisation in machine learning interatomic potentials. It comprises four tasks that test models on unseen molecules, designed so that learning underlying chemical principles should enable generalisation. Experiments show that current state‑of‑the‑art models struggle, with out‑of‑distribution errors often an order of magnitude higher than in‑distribution errors, even for foundation models pre‑trained on millions of molecules.

Active Learning Enables Generation of Molecules that Advance the Known Pareto Front

The paper presents a closed‑loop molecule generation pipeline that iteratively retrains on new quantum‑chemical simulation data, overcoming limitations of static generative models. This approach produces molecules whose properties extend up to 0.44 standard deviations beyond the training set and improves out‑of‑distribution classification accuracy by 79%. By conditioning on thermodynamic stability during the loop, the method yields a 3.5‑fold increase in the proportion of stable, potentially synthesizable molecules.

General-purpose foundation models surpass specialized ones on chemical property prediction tasks

The study compares chemical foundation models (ChemBERTa, MoLFormer) with general‑purpose models (GPT‑6 Astra, Claude Opus 5.5) on chemical property prediction tasks. On five physicochemical and quantum‑chemical regression tasks with only 60 experimental datapoints, GPT‑6 Astra outperforms the specialized chemical models. When the chemical models receive ten times more data (1,000–10,000 points), they match GPT‑6 Astra’s performance at 60–1,000 points, indicating that general‑purpose models trained on broad knowledge can be more effective in data‑scarce chemical research.
