WebbThe goal of SHAP is to explain a machine learning model’s prediction by calculating the contribution of each feature to the prediction. The technical explanation is that it does this by computing Shapley values from coalitional game theory. Of course, if you’re unfamiliar with game theory and data science, that may not mean much to you. Webb2.1. Classical Shapley values In cooperative game theory, a coalitional game consists of a set of Nplayers and a characteristic function vwhich maps subsets S f1;2;:::;Ngto a real value v(S), satisfying v(;) = 0. The value function represents how much collec-tive payoff a set of players can gain by “cooperating” as a set.

Webb20 nov. 2024 · As mentioned above, Shapley values are based on classic game theory. There are many game types such as cooperative/non-cooperative, symmetric/non-symmetric, zero-sum/non zero-sum etc. But Shapley values are based on the cooperative (coalition) game theory. In coalition game theory, a group of players comes together to … Webb2 Game theory and SHAP (Shapley additive explanation) values From a game theory perspective, a modelling exercise may be rationalised as the superposition of multiple collaborative games where, in each game, agents (explanatory variables) strategically interact to achieve a goal – making a prediction for a single observation.
