Shap values explanation
Webb11 jan. 2024 · They combined Shapley values with several other model explanation methods to create SHAP values (SHapley Additive exPlanations) and the corresponding … WebbIn this study, we used the SHAP and LIME algorithms as interpretation algorithms of the ML black box model. 19–21. The SHAP algorithm is a game theoretical approach that explains the output of any ML model. It connects optimal credit allocation with local explanations using the classic Shapley values from game theory.
