Median rank of the descriptor sets in the bioactivity benchmarks. The median is calculated over all 14 ranks (1 rank per dataset, per experiment, per validation type), also shown the median average deviation (MAD). The best three descriptor sets have a median rank < 5 among which the combinations of Z-scales (3) with other descriptors perform the best. The worst performance is by BLOSUM, ProtFP (PCA8), ST-scales and ProtFP (Feature) with a mean rank > 11. BLOSUM has a large standard deviation due to its inconsistent performance.
