Fig. 5From: Naturally-meaningful and efficient descriptors: machine learning of material properties based on robust one-shot ab initio descriptorsa The feature importance matrix for predicting the properties by the descriptor groups outlined in Section “Features”. The properties shown include the (b) HOMO–LUMO gap EHOMO-LUMO (in eV), (c) the isotropic polarizability α (in Bohr3) and (d) the free energy G (in eV)Back to article page
