MSI: A Mahalanobis‐Based Molecular Similarity Index for High‐Dimensional Embeddings

Molecular Informatics, Volume 45, Issue 9, September 2026.
MSI pairs continuous Mol2Vec embeddings with a covariance‐aware Mahalanobis metric (dM, θM) to overcome the ranking ties and bit‐density bias of Tanimoto fingerprints. Across five reference compounds, MSI resolves more distinct neighbors than ECFP4 + Tanimoto and its geometry tracks HOMO–LUMO gaps in QM9, despite no electronic training.
