Webb9.5 Shapley Values. 9.5. Shapley Values. A prediction can be explained by assuming that each feature value of the instance is a “player” in a game where the prediction is the payout. Shapley values – a method from coalitional game theory – tells us how to fairly distribute the “payout” among the features.

Webb2 feb. 2024 · SHAP values are average marginal contributions over all possible feature coalitions. They just explain the model, whatever the form it has: functional (exact), or tree, or deep NN (approximate). They are as good as the underlying model. – Sergey Bushmanov Feb 4, 2024 at 14:26 WebbShapley value regression functions in Python are used to interpret machine learning models. It facilitates the easy distribution of calculations and payoffs. If there is a model where predictions are known, then the Shapley solution can be applied to find the difference between the actual value and the predicted value. theoretical resolving power
