Webb21 juli 2024 · Model Explainability – SHAP vs. LIME vs. Permutation Feature Importance. July 21, 2024. Last Updated on July 21, 2024 by Editorial Team. WebbThe way permutation importance works is to shuffle the input data and apply it to the pipeline (or the model if that is what you want). In fact, if you want to understand how the initial input data effects the model then you should apply it to the pipeline.
