WebbImportance weights focus on how much each row of the data set should influence model estimation. These can be based on data or arbitrarily set to achieve some goal. In … WebbThe feature importance measurement includes the importance of the raw feature term and all the decision rules in which the feature appears. Interpretation template The interpretation is analogous to linear models: The predicted outcome changes by $\beta_j$ if feature $x_j$ changes by one unit, provided all other features remain unchanged.
