All Implemented Interfaces:

StructuralLearning

public final class TANStructuralLearning
extends Object
implements StructuralLearning

A structural learning algorithm for Bayesian networks based on the Tree augmented naive Bayes (TAN) algorithm.

This algorithm uses tests (e.g. mutual information) conditional on a target to build a spanning tree, which is then directed to construct a Bayesian network with additional links added from the target. Often used for classification of the target.
