Shap waterfall plot random forest

WebbThe waterfall plot is designed to visually display how the SHAP values (evidence) of each feature move the model output from our prior expectation under the background data … Webbshap.summary_plot(shap_values, X.values, plot_type="bar", class_names= class_names, feature_names = X.columns) In this plot, the impact of a feature on the classes is stacked to create the feature importance plot. Thus, if you created features in order to differentiate a particular class from the rest, that is the plot where you can see it.
