FeAl 2 O 4 have found good agreement between DFT+U, hybrid functional, and the random phase approximation, but uncertainties on the order of a few tenths of an eV should be expected for DFT calculations in transition metal oxides. We therefore extend the defect screening metrics to be uncertainty inclusive (x min,1 , x rng,1 ), agnostic (x min,2 , x rng,2 ), or exclusive (x min,3 , x rng,3 ) for increasingly strict down-selection. Given a host's N s symmetry sites and the set of all predictions { ∆ ĤO ) to narrow the list of potential STCH candidates. At each down-selection stage, we show the number of unique remaining formulas, the number of which overlap with the training data, and an exemplar structure.
