             Summary: Feature Importance for GBT
                 Key: SPARK-11730
                 URL: https://issues.apache.org/jira/browse/SPARK-11730
             Project: Spark
          Issue Type: New Feature
          Components: ML, MLlib
            Reporter: Brian Webb


Random Forests have feature importance, but GBT do not. It would be great if we 
can add feature importance to GBT as well. Perhaps the code in Random Forests 
can be refactored to apply to both types of ensembles.

See https://issues.apache.org/jira/browse/SPARK-5133
