Description

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.
