XWP and XWP_c are novel attribution methods for FCNNs that estimate feature importance by perturbing attached weights to avoid added bias and out-of-distribution issues in occlusion approaches.

Counterfactual baselines for Integrated Gradients yield more faithful and medically relevant attributions than standard baselines across three medical datasets.
Path-sampled integrated gradients generalizes integrated gradients by averaging gradients over sampled baselines on the linear path, proving equivalence to a weighted version that improves convergence rate to O(m^{-1}) and reduces variance by a factor of 1/3 under uniform sampling.
