Class M5Rules

java.lang.Object

weka.classifiers.AbstractClassifier

weka.classifiers.trees.m5.M5Base

weka.classifiers.rules.M5Rules

All Implemented Interfaces:

Serializable, Cloneable, Classifier, AdditionalMeasureProducer, CapabilitiesHandler, OptionHandler, RevisionHandler, TechnicalInformationHandler

public class M5Rules
extends M5Base
implements TechnicalInformationHandler

Generates a decision list for regression problems using separate-and-conquer. In each iteration it builds a model tree using M5 and makes the "best" leaf into a rule.

Valid options are:

 -N
  Use unpruned tree/rules

 -U
  Use unsmoothed predictions

 -R
  Build regression tree/rule rather than a model tree/rule

 -M <minimum number of instances>
  Set minimum number of instances per leaf
  (default 4)
