Welcome 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).

Feb 29, 2020 · So, as expected the biggest difference between the Kernel SHAP and the LIME sample weighting strategies is seen when only a few features are present: LIME attributes a small weight to those samples because they are far from the datapoint being investigated, while Kernel SHAP attributes a large weight to it because it isolates the individual behavior of features.

The reason is kernel shap sends data as numpy array which has no column names. so we need to fix it as follows: def model_predict(data_asarray): data_asframe = pd.DataFrame(data_asarray, columns=feature_names) return estimator.predict(data_asframe)

Simple Kernel SHAP ¶. Simple Kernel SHAP. This notebook provides a simple brute force version of Kernel SHAP that enumerates the entire 2 M sample space. We also compare to the full KernelExplainer implementation. Note that KernelExplainer does a sampling approximation for large values of M, but for small values it is exact.
