[jira] [Created] (HIVEMALL-233) RandomForest regressor accepts sparse vector input

Takuya Kitazawa created HIVEMALL-233:
----------------------------------------

             Summary: RandomForest regressor accepts sparse vector input
                 Key: HIVEMALL-233
                 URL: https://issues.apache.org/jira/browse/HIVEMALL-233
             Project: Hivemall
          Issue Type: Improvement
            Reporter: Takuya Kitazawa
            Assignee: Takuya Kitazawa


While HIVEMALL-75 has enabled RandomForestClassifier to accept sparse vector as an input, some crucial code in the classifier is not properly implemented in its regressor counterpart; input feature vector is processed differently by regressor and classifier.

This ticket follows up to HIVEMALL-75 so that the regressor behaves similarly to the classifier.
