      • 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

                                    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
