The Shapley value is a concept from game theory that quantifies how much each player contributes to the game outcome (Shapley 1953). The concept, however, has many more use cases: it provides a method to quantify the importance of predictors in regression analysis or machine learning models, and can be used in a wide variety of …

WebbThere are two reasons why SHAP got its own chapter and is not a subchapter of Shapley values.First, the SHAP authors proposed KernelSHAP, an alternative, kernel-based estimation approach for … WebbShapley regression (also known as dominance analysis or LMG) is a computationally intensive method popular amongst researchers. To describe the calculation of the score of a predictor variable, first consider the difference in R2 from adding this variable to a model containing a subset of the other predictor variables.
