Package weka.classifiers.meta

Class RangeCheck

  • All Implemented Interfaces:
    Serializable, Cloneable, weka.classifiers.Classifier, RangeCheckClassifier, weka.core.BatchPredictor, weka.core.CapabilitiesHandler, weka.core.CapabilitiesIgnorer, weka.core.CommandlineRunnable, weka.core.OptionHandler, weka.core.RevisionHandler
    public class RangeCheck
extends weka.classifiers.SingleClassifierEnhancer
implements RangeCheckClassifier
    Keeps track of the ranges in case of numeric attributes. It then allows checks whether an instance is for one or more attributes outside the training range.

    Valid options are: 

     -D
  If set, classifier is run in debug mode and
  may output additional info to the console
     -W
  Full name of base classifier.
  (default: weka.classifiers.rules.ZeroR)
     
 Options specific to classifier weka.classifiers.rules.ZeroR:
 
     -D
  If set, classifier is run in debug mode and
  may output additional info to the console
