lazy val featureImportances: Vector
Estimate of the importance of each feature.
Estimate of the importance of each feature.
This generalizes the idea of "Gini" importance to other losses, following the explanation of Gini importance from "Random Forests" documentation by Leo Breiman and Adele Cutler, and following the implementation from scikit-learn.
This feature importance is calculated as follows:
- importance(feature j) = sum (over nodes which split on feature j) of the gain, where gain is scaled by the number of instances passing through node
- Normalize importances for tree to sum to 1.
Annotations
@Since( "2.0.0" )
Note
Feature importance for single decision trees can have high variance due to correlated predictor variables. Consider using a RandomForestClassifier to determine feature importance instead.
