Webb28 maj 2024 · When looking at the source code on Github, the summary_plot function does seem to have a 'features' attribute. However, this does not seem to be the solution to my problem. Could anybody help me plot a specific set of features, or is this not a viable option in the current code of SHAP. python plot shap Share Follow asked May 28, 2024 at 15:00 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.
