## Class M5Rules

- java.lang.Object
- - weka.classifiers.AbstractClassifier
  - - weka.classifiers.trees.m5.M5Base
    - - weka.classifiers.rules.M5Rules

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, Classifier, AdditionalMeasureProducer, CapabilitiesHandler, CapabilitiesIgnorer, 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)
