class DecisionTree

A decision-tree classifier. Given a set of training Example s, builds a model by randomly choosing subsets of features and the training set, and then finding a binary com.cloudera.oryx.app.rdf.decision.Decision over those features and datathat produces the largest information gain in the two subsets it implies. This is repeated to build a tree of DecisionNode s. At the bottom, leaf nodes are formed ( TerminalNode ) that contain a Prediction of the target value.
