Abstract

Machine learning (ML)-based feature analysis reveals universal design rules regardless of density functional choices. Using the consensus among multiple functionals, we identify robust lead complexes in ML-accelerated chemical discovery.

  • By applying random forest-ranked recursive feature addition to KRR models, expected heuristics have been reinforced by feature selection approaches, such as the spin splitting of a complex being strongly dependent on the metal-local electronic environment.

    “By applying random forest-ranked recursive feature addition to KRR models, expected heuristics have been reinforced by feature selection approaches (22,32,105), such as the spin splitting of a complex being strongly dependent on the metal-local electronic environment (e.g., from the electronegativities of surrounding atoms; Figure 5)”
  • Conversely, other properties, such as the frontier orbital energies, band gap, or ionization/redox potential, depend much more on the global structure of the molecule.

    “Conversely, other properties, such as the frontier orbital energies (22), band gap (44, 105), or ionization/redox potential (32,52), depend much more on the global structure of the molecule (Figure 5).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
