a The attribution visualization of compound 1; b The attribution visualization of compound 2; c The attribution of the different functional groups in the whole ESOL dataset. Only the functional groups that appear more than ten times in the dataset are included in Fig. 1. Blue colors represent attributions lower than 0 and the substructure is favorable for hydrophilicity, while orange colors represent attributions higher than 0 and the substructure is unfavorable for hydrophilicity.
