Webb2 jan. 2024 · shap.plots.scatter (shap_values [:,"RM"], color=shap_values) 어떤 변수가 모델에 가장 중요한지에 대한 대략적인 내용을 얻으려면 모든 샘플에 대한 모든 변수의 SHAP 값을 플롯 할 수 있어요. 아래 플롯은 모든 샘플에 대한 SHAP 값 크기의 합으로 변수를 정렬하고, SHAP 값을 사용하여 각 변수가 모델 결과에 미치는 영향의 분포를 보여줍니다. … WebbSHAP do not compute the Shapley value; cohort and baseline Shapley do compute it. We include Monte Carlo versions of them because they are consistent for the Shapley value as computation increases. LIME requires the choice a surrogate model and a kernel, so we do not consider it to be automatic.

By definition, the Shapley value is the … WebbShapley values are the only solution that satisfies properties of Efficiency, Symmetry, Dummy and Additivity. SHAP also satisfies these, since it computes Shapley values. In the SHAP paper, you will find …

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).
