Shapley value sampling
WebbShapley computes feature contributions for single predictions with the Shapley value, an approach from cooperative game theory. The features values of an instance cooperate … WebbThe current state-of-the-art criterion for pruning in a low-data regime approximates Shapley values via Monte Carlo sampling. Computing the actual Shapley values would be optimal, however, calculating the Shapley value for a single image has a high computational complexity, which limits the application of this method.

WebbShapley Values. A prediction can be explained by assuming that each feature value of the instance is a “player” in a game where the prediction is the payout. Shapley values – a … Webbclassification trees and SHapley Additive exPlanations (SHAP) analysis to explore the errors in the prediction of lightning occurrence in the NASA GEOS model, ... these techniques calculate SHAP values through sampling the predictions of a given model by replacing some model input values with random values from that input distribution.
WebbShapley values using the alternative cost function EV u = E[V(˚(X)jX u)] are equal to the ones using VE u [17], which thus provides an alternative way to compute them. We call VE u and EV u the conditional indices. Practical interest and theoretical properties of Shapley values for GSA have been widely studied since their introduction [17– 19]. WebbAccordingly, the population Shapley value v 1 (i) is unique to sample i, and thus we adjust the coverage estimator covr ^ v 1 ([L, U]) by replacing v 1 on the RHS of Eq. 12 by v 1 (i). …
The Shapley value has many desirable properties. The sum of the Shapley values of all agents equals the value of the grand coalition, so that all the gain is distributed among the agents: Proof: since is a telescoping sum and there are N ! different orderings R.
