“…Simple, basic atomic and physicochemical features were calculated for the dataset ( Lu et al., 2019 ). Each component of the photocatalysts (A, A’, B, B’) was described by 14 features obtained from the periodic table, materials handbooks, and material databases ( Table S1 ) ( Li et al., 2019 , 2020a ; Lu et al., 2019 ; Rajan et al., 2018 ). To refine the number of features to the most relevant subset the full descriptor set of 57 features (56 features related to A, A’, B and B’, while n x is the amount of O) was subjected to feature selection.…”
