WebbSHAP do not compute the Shapley value; cohort and baseline Shapley do compute it. We include Monte Carlo versions of them because they are consistent for the Shapley value as computation increases. LIME requires the choice a surrogate model and a kernel, so we do not consider it to be automatic. WebbThe authors have reported an F1 score value of up to 83.29%.
