Tree SHAP is a fast and exact method to estimate SHAP values for tree models and ensembles of trees, under several different possible assumptions about feature dependence. It depends on fast C++ implementations either inside an externel model package or in the local compiled C extention. Parameters modelmodel object

shap_explainer_model = shap.TreeExplainer(RF_best_parameters, data=X_train, feature_perturbation="interventional", model_output="raw") Then the shap_explainer_model.expected_value should give you the mean prediction of your model on train data. Otherwise, TreeExplainer uses feature_perturbation="tree_path_dependent"; accoding to …

shap.LinearExplainer¶ class shap.LinearExplainer (model, data, nsamples = 1000, feature_perturbation = None, ** kwargs) ¶. Computes SHAP values for a linear model, optionally accounting for inter-feature correlations. This computes the SHAP values for a linear model and can account for the correlations among the input features.
