[jira] [Created] (SPARK-12886) Expose params to control how feature names are generated

Xiangrui Meng created SPARK-12886:
-------------------------------------

             Summary: Expose params to control how feature names are generated
                 Key: SPARK-12886
                 URL: https://issues.apache.org/jira/browse/SPARK-12886
             Project: Spark
          Issue Type: New Feature
          Components: ML
            Reporter: Xiangrui Meng


Feature names are generated during feature transformations. This would cause performance issues if there are a huge number of features. Sometimes, it is not useful to have feature names if the features are not to be examined manually. It would be nice to expose params to control feature name generation. This could be part of attribute API improvement.
