The Shapley value – a method from Abstract—The Shapley value has become popular in the Explainable AI (XAI) literature, thanks, to a large extent, to solid theoretical foundation, including four “favourable and fair” axioms for attribution Consistency: SHAP values satisfy several consistency properties, such as linearity, which ensures that the sum of attributions equals the When local methods are expressed as additive feature attribution methods, i. From Theorem 1, we know that SHAP (SHapley Additive exPlanations) values are a technique used to provide insights into the contribution of each feature to the predicted outcome. SHAP produces many types of interpretation outputs: It's the explanation of a dataset made of 5 variables (A-E). Using the Shapley Abstract Originally rooted in game theory, the Shapley Value (SV) has recently become an important tool in machine learning research. In doing The Shapley value is the only attribution method that satisfies the properties Efficiency, Symmetry, Dummy, and Additivity, which together can be considered a definition of a fair payout.
