java.lang.Objectweka.filters.Filter
weka.filters.unsupervised.instance.RemoveMisclassified
public class RemoveMisclassified
A filter that removes instances which are incorrectly classified. Useful for removing outliers.
Valid options are:-W <classifier specification> Full class name of classifier to use, followed by scheme options. eg: "weka.classifiers.bayes.NaiveBayes -D" (default: weka.classifiers.rules.ZeroR)
-C <class index> Attribute on which misclassifications are based. If < 0 will use any current set class or default to the last attribute.
-F <number of folds> The number of folds to use for cross-validation cleansing. (<2 = no cross-validation - default).
-T <threshold> Threshold for the max error when predicting numeric class. (Value should be >= 0, default = 0.1).
-I The maximum number of cleansing iterations to perform. (<1 = until fully cleansed - default)
-V Invert the match so that correctly classified instances are discarded.
