Table 4. Feature Extraction and Ranking.

algorithm for feature extraction and ranking
1 compute and extract all geometric (clustering) and chemical features of putative pockets with appropriate normalization
2 load 2 pairs (geometry and chemistry) of pretrained Isolation Forests (IFs): one trained on the “large” pockets, and one trained on the “small” (sub)pockets; the former is the main score, while the latter is used only to compare subpockets with each other
3 compute the anomaly score from the (main) geometric and chemical IFs; rank all putative pockets according to the average score
4 if any, rank the subpockets within each pocket
5 return to the user the pockets ranked according to point 3, and provide the subrank of subpockets, if any, according to point 4
