public class CT
extends MCC
implements weka.core.TechnicalInformationHandler

CT - Classifier Trellis. CC in a trellis structure (rather than a cascaded chain). You set the width and type/connectivity/density of the trellis, and optionally change the dependency heuristic which guides the placement of nodes (labels) within the trellis.
