65% of RF-RFA RF-selected features are present in the KRR-selected feature set (Supporting Information Table ). While RF-RFA KRR-selected features also identify global features to be most important, a small fraction of metal-proximal second coordination sphere features are also selected (Figure ). Additionally, we observe comparable numbers of electronic and geometric features (52% vs 48%) in this feature set, confirming the robustness of our selected features to the ML model (Figure ). are grouped by the most metal-distal atoms: more distant, global features in gray, third coordination sphere features in orange, and second coordination sphere features in green. Within each connectivity distance category, the property (i.e., c, S, T, Z, or I) is indicated. Following our previous work, we have categorized c and Z as electronic features, with all remaining features categorized as geometric.
