Webb17 maj 2024 · shap.summary_plot (shap_values,X_test,feature_names=features) Each point of every row is a record of the test dataset. The features are sorted from the most important one to the less important. We can see that s5 is the most important feature. The higher the value of this feature, the more positive the impact on the target.
