Webb2.2. Shapley values for feature importance Several methods have been proposed to apply the Shapley value to the problem of feature importance. Given a model f(x 1;x 2;:::;x d), the features from 1 to dcan be considered players in a game in which the payoff vis some measure of the importance or influence of that subset. The Shapley value ˚ Webb14 sep. 2016 · For a game where a group of players cooperate, and where the expected payoff is known for each subset of players cooperating, one can calculate the Shapley value for each player, which is a way of fairly determining the contribution of each player to the payoff. I assume in the regression case we do not know what the expected payoff is.
Webb18 juli 2024 · It is possible to do this by passing a function handle to shapley.This function handle needs to output the score for the class of interest. Also, shapley expects inputs and outputs for the function handle to be row vectors rather than column vectors, so some transposes are needed.
