Class NormalizeAdaptive

java.lang.Object
  weka.filters.Filter
      weka.filters.unsupervised.attribute.PotentialClassIgnorer
          weka.filters.unsupervised.attribute.NormalizeAdaptive

All Implemented Interfaces:

Serializable, weka.core.CapabilitiesHandler, 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.

NormalizeAdaptive

public NormalizeAdaptive()

Method Detail

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

Capabilities

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

setScale

public void setScale(double fScale)

getScale

public double getScale()

setClassIndex

public void setClassIndex(int classIndex)

getClassIndex

public int getClassIndex()

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

getRevision

public String getRevision()

Specified by:

getRevision in interface weka.core.RevisionHandler

Overrides:

getRevision in class weka.filters.Filter
