[jira] [Commented] (SPARK-9715) Store numFeatures in all ML PredictionModel types

    [ https://issues.apache.org/jira/browse/SPARK-9715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14735065#comment-14735065 ] 

Seth Hendrickson commented on SPARK-9715:
-----------------------------------------

I can take this one if no one else has started it. Plan is to add abstract method {{def numFeatures: Int}} to the {{PredictionModel}} abstract class and implement methods for each learning model that inherits from PredictionModel.
