Variable importance in the RF models for lattice centering, crystal system, Bravais lattice, point group and space group. For brevity, only the ten most influential variables are shown for each symmetry category. The length of the bars is a quantitative measure of the decrease in accuracy upon removal of the variable from the set of descriptors. Gaps, i.e. absence, of a bar for a variable in a symmetry category indicate that the variable is not among the top-ten contributors. More information on each descriptor can be found in the SI. |
