The shapley value method
WebIntuitively, the Shapley value can be understood as a weighted average of a player’s marginal contributions to every possible subset of players. Let be the set of per-mutations of the integers up to N, and given ˇ 2 let S i;ˇ= fj: ˇ(j) WebShapley value is the derivation of the applied cost and gained profit—distributed equally among the players—based on individual contribution. In machine learning, Shapley values employ game theory to identify the exact contribution of each player. In addition, the Shapley method explains projections made by nonlinear models.
