Class SparkDecisionTreeModel

java.lang.Object

org.apache.lens.ml.algo.spark.dt.SparkDecisionTreeModel

All Implemented Interfaces:

Serializable, org.apache.spark.mllib.classification.ClassificationModel

public class SparkDecisionTreeModel
extends Object
implements org.apache.spark.mllib.classification.ClassificationModel

This class is created because the Spark decision tree model doesn't extend ClassificationModel.
