Test set performance of RF-Score with
element descriptors and 12 Å interatomic distance cutoff using
six different bin sizes (1 Å, 2 Å, 3 Å, 4 Å, 6
Å, and 12 Å). The best median performance is achieved by
models with lower bin sizes (1 Å, 2 Å, and 3 Å), representing
a modest improvement with respect to the model based on single-binned
descriptors (12 Å).
