Table 3 Relative area under the curve (AUC) values for the different perturbation schemes and models. Bold cells mark the highest score per row and italic cells the second-highest. Methods that have not reached first or second rank once were omitted for readability. LRP, layerwise relevance propagation; DTD, deep Taylor decomposition; ITG, input times gradient.
