public class DatasetCleaner
extends AbstractColumnFinderApplier

Removes all columns from the data data that have been indentified.

Valid options are:

 -D
  Turns on output of debugging information.

 -W <column finder specification>
  Full class name of column finder to use, followed
  by scheme options. eg:
   "adams.data.weka.columnfinder.NullFinder -D 1"

Constructor Detail

DatasetCleaner

public DatasetCleaner()

Method Detail

globalInfo

public String globalInfo()

Returns a string describing this classifier.

Specified by:

globalInfo in class weka.filters.SimpleFilter

Returns:

a description of the classifier suitable for displaying in the explorer/experimenter gui

columnFinderTipText

public String columnFinderTipText()

Returns the tip text for this property.

Specified by:

columnFinderTipText in class AbstractColumnFinderApplier

Returns:

tip text for this property suitable for displaying in the explorer/experimenter gui

determineOutputFormat

protected weka.core.Instances determineOutputFormat(weka.core.Instances inputFormat)
                                             throws Exception

Determines the output format based on the input format and returns this. In case the output format cannot be returned immediately, i.e., immediateOutputFormat() returns false, then this method will be called from batchFinished().

Specified by:

determineOutputFormat in class AbstractColumnFinderApplier

Parameters:

inputFormat - the input format to base the output format on

Returns:

the output format

Throws:

Exception

apply

protected weka.core.Instances apply(weka.core.Instances data,
                                    int[] indices)

Applies the indices to the data. In case inverting is enabled, the indices have already been inverted.

Specified by:

apply in class AbstractColumnFinderApplier

Parameters:

data - the data to process

indices - the indices to use

Returns:

the processed data

getRevision

public String getRevision()

Returns the revision string.

Specified by:

getRevision in interface weka.core.RevisionHandler

Overrides:

getRevision in class weka.filters.Filter

Returns:

the revision
