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.

      • globalInfo

        public String globalInfo()
        Returns a string describing this filter
        Returns:
        a description of the filter suitable for displaying in the explorer/experimenter gui

      • getCapabilities

        public weka.core.Capabilities getCapabilities()
        Returns the Capabilities of this filter.
        Specified by:
        getCapabilities in interface weka.core.CapabilitiesHandler
        Overrides:
        getCapabilities in class weka.filters.Filter
        Returns:
        the capabilities of this object

      • setInputFormat

        public boolean setInputFormat​(weka.core.Instances instanceInfo)
                       throws Exception
        Sets the format of the input instances.
        Overrides:
        setInputFormat in class weka.filters.unsupervised.attribute.PotentialClassIgnorer
        Parameters:
        instanceInfo - an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required).
        Returns:
        true if the outputFormat may be collected immediately
        Throws:
        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.
        Overrides:
        input in class weka.filters.Filter
        Parameters:
        instance - the input instance
        Returns:
        true if the filtered instance may now be collected with output().
        Throws:
        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.
        Overrides:
        batchFinished in class weka.filters.Filter
        Returns:
        true if there are instances pending output
        Throws:
        IllegalStateException - if no input structure has been defined

      • main

        public static void main​(String[] argv)
        Main method for testing this class.
        Parameters:
        argv - should contain arguments to the filter: use -h for help
