Webb8 dec. 2024 · We can demonstrate the significance of this difference with a simple artificial example. Let’s generate a 3-feature linear regression model, with one feature x 1 which is a strong predictor of y , a second feature x 2 which is strongly correlated with it (and so slightly less predictive of y ), and a third non-predictor feature x 3 : WebbPermutation Feature Importance is a technique used to explain classification and regression models that is inspired by Breiman’s Random Forests paper (see section 10). At a high level, the way it works is by randomly shuffling data one feature at a time for the entire dataset and calculating how much the performance metric of interest changes.
