Shapley values
Webb2 maj 2024 · Shapley values . The Shapley value (SHAP) concept was originally developed to estimate the importance of an individual player in a collaborative team [20, 21]. This concept aimed to distribute the total gain or payoff among players, depending on the relative importance of their contributions to the final outcome of a game.Webb22 maj 2024 · SHAP assigns each feature an importance value for a particular prediction.
