ML Model Interpretability : ELI5 & Permutation Importance - Medium
Web28. dec 2024 · For metrics where lower values indicate better model performance, more negative permutation variable importance values indicate features that are more important. Because this may cause confusion, values obtained for these metrics are mirrored around 0.0 for plotting (but not any tabular data export). Web29. mar 2024 · Feature importance refers to techniques that assign a score to input features based on how useful they are at predicting a target variable.
