Class NormalizeAdaptive

  • All Implemented Interfaces:
    Serializable, weka.core.CapabilitiesHandler, weka.core.CapabilitiesIgnorer, weka.core.CommandlineRunnable, weka.core.OptionHandler, weka.core.RevisionHandler, weka.filters.UnsupervisedFilter

    public class NormalizeAdaptive
    extends weka.filters.unsupervised.attribute.PotentialClassIgnorer
    implements weka.filters.UnsupervisedFilter
    Normalizes all numeric values in the given dataset (apart from the class attribute, if set). The resulting values are in [0,1] for the data used to compute the normalization intervals.

      • setInputFormat

        public boolean setInputFormat​(weka.core.Instances instanceInfo)
                               throws Exception
        Sets the format of the input instances.
        setInputFormat in class weka.filters.unsupervised.attribute.PotentialClassIgnorer
        instanceInfo - an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required).
        true if the outputFormat may be collected immediately
        Exception - if the input format can't be set successfully
      • input

        public boolean input​(weka.core.Instance instance)
        Input an instance for filtering. Filter requires all training instances be read before producing output.
        input in class weka.filters.Filter
        instance - the input instance
        true if the filtered instance may now be collected with output().
        IllegalStateException - if no input format has been set.
      • batchFinished

        public boolean batchFinished()
        Signify that this batch of input to the filter is finished. If the filter requires all instances prior to filtering, output() may now be called to retrieve the filtered instances.
        batchFinished in class weka.filters.Filter
        true if there are instances pending output
        IllegalStateException - if no input structure has been defined
