Package org.seasr.meandre.components.prediction.decisiontree.c45

DESCRIPTION

Overview: Given a DecisionTreeNode that is the root of a decision tree, creates a new DecisionTreeModel.Detailed Description: Creates a DecisionTreeModel from Decision Tree Root. The Example Tablemust be the same set of examples used to construct the decision tree.Data Type Restrictions: Output feature must be nominal.Data Handling: This module will create a PredictionTable from Example Table and proceed to make a prediction for each example in Example Table.Scalability: This module will make a prediction for each example in Example Table. There must be sufficient memory to hold these predictions.
