Webb25 nov. 2024 · Now, if we talk in terms of Game Theory, the “game” here is the prediction task for a single instance of the dataset. The “players” are the feature values of the instance that collaborate to play the game (predict a value) similar to the meal example where Pranav, Ram, and Abhiraj went for a meal together. WebbWelcome to the SHAP Documentation¶. SHAP (SHapley Additive exPlanations) is a game theoretic approach to explain the output of any machine learning model. It connects optimal credit allocation with local explanations using the classic Shapley values from game theory and their related extensions (see papers for details and citations.
