[jira] [Created] (SPARK-2206) Automatically infer the number of classification classes in multiclass classification

Manish Amde created SPARK-2206:
----------------------------------

             Summary: Automatically infer the number of classification classes in multiclass classification
                 Key: SPARK-2206
                 URL: https://issues.apache.org/jira/browse/SPARK-2206
             Project: Spark
          Issue Type: New Feature
          Components: MLlib
            Reporter: Manish Amde


Currently, the user needs to specify the numClassesForClassification parameter explicitly during multiclass classification for decision trees. This feature will automatically infer this information (and possibly class histograms) from the training data.
