Webb29 juni 2024 · The Random Forest algorithm has built-in feature importance which can be computed in two ways: Gini importance(or mean decrease impurity), which is computed from the Random Forest structure. Let’s look at how the Random Forest is constructed. It is a set of Decision Trees. Each Decision Tree is a set of internal nodes and leaves.

I am trying to plot SHAP This is my code rnd_clf is a RandomForestClassifier: import shap explainer = shap.TreeExplainer (rnd_clf) shap_values = explainer.shap_values (X) shap.summary_plot (shap_values [1], X) I understand that shap_values [0] is negative and shap_values [1] is positive. Webb28 nov. 2024 · SHAP (SHapley Additive exPlanation) values are one of the leading tools for interpreting machine learning models. Even though computing SHAP values takes exponential time in general, TreeSHAP takes polynomial time on tree-based models (e.g., decision trees, random forest, gradient boosted trees). razor cut keri hilson short hairstyles
