WebbEach feature’s Shapley value is the contribution of the feature for all possible subsets of the other features. The “kernel SHAP” method from the SHAP paper computes the Shapley values of all features simultaneously by defining a weighted least squares regression whose solution is the Shapley values for all the features. WebbSHAP assigns each feature an importance value for a particular prediction. Its novel components include: (1) the identification of a new class of additive feature importance measures, and (2) theoretical results showing there is a unique solution in this class with a set of desirable properties.
