Shap global importance
Webb23 okt. 2024 · Please note here that SHAP can calculate the Global Feature Importances inherently, using summary plots. Hence, once the shapely values are calculated, it’s good to visualize the global feature importance with summary plot, which gives the impact (positive and negative) of a feature on the target: shap.summary_plot (shap_values, X_test) Webb22 juni 2024 · Boruta-Shap. BorutaShap is a wrapper feature selection method which combines both the Boruta feature selection algorithm with shapley values. This combination has proven to out perform the original Permutation Importance method in both speed, and the quality of the feature subset produced. Not only does this algorithm …
