SHAP (SHapley Additive exPlanations) by Lundberg and Lee (2017)[^lundberg2017] is a method to explain individual predictions.
SHAP is based on the game theoretically optimal [Shapley values](#shapley).

There are two reasons why SHAP got its own chapter and is not a subchapter of [Shapley values](#shapley).
First, the SHAP authors proposed KernelSHAP, an alternative, kernel-based estimation approach for Shapley values inspired by [local surrogate models](#lime).
And they proposed TreeSHAP, an efficient estimation approach for tree-based models.
