Class NSR

java.lang.Object

weka.classifiers.AbstractClassifier

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, MultiTargetClassifier, weka.classifiers.Classifier, weka.core.CapabilitiesHandler, weka.core.OptionHandler, weka.core.Randomizable, weka.core.RevisionHandler, weka.core.TechnicalInformationHandler

public class NSR
extends PS
implements MultiTargetClassifier

NSR.java - The Nearest Set Relpacement (NSR) method. A multi-target version of PS: The nearest sets are used to replace outliers, rather than subsets (as in PS). Important Note: currently can only handle 10 values (or fewer) per target variable.
