WebbGame Theory Professor Giacomo Bonanno COOPERATIVE GAMES: the SHAPLEY VALUE The description of a cooperative game is still in terms of a characteristic function which specifies for every group of players the total payoff that the members of S can obtain by signing an agreement among themselves; this payoff is available for distribution among … WebbIn , based on the theory of cooperative games, a Shapley value was calculated to allocate peaking compensation fees according to the marginal contribution of peaking providers. As the most common method for solving cooperative game problems, there is a “combination explosion” problem when a Shapley value is applied in large-scale systems [ 14 , 15 , 16 ].

SHAP values are based on Shapley values, a concept coming from game theory. But game theory needs at least two things: a game and some players. How does this apply to machine learning explainability? Imagine that we have a predictive model, then: the “game” is reproducing the outcome of the model,
