        public String globalInfo()
        Returns a string describing this classifier.
        Specified by:
        globalInfo in class weka.filters.SimpleFilter
        a description of the classifier suitable for displaying in the explorer/experimenter gui
      • columnFinderTipText

        public String columnFinderTipText()
        Returns the tip text for this property.

        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
        inputFormat - the input format to base the output format on
        the output format

        Specified by:
        apply in class AbstractColumnFinderApplier
        data - the data to process
        indices - the indices to use
