Class RowSum

  • All Implemented Interfaces:
    Serializable, weka.core.CapabilitiesHandler, weka.core.CapabilitiesIgnorer, weka.core.CommandlineRunnable, weka.core.OptionHandler, weka.core.RevisionHandler, weka.filters.StreamableFilter, weka.filters.UnsupervisedFilter

    public class RowSum
    extends weka.filters.SimpleStreamFilter
    implements weka.filters.UnsupervisedFilter
    Sums up all numeric values in a row and replaces them with it.

    Valid options are:

      If set, filter is run in debug mode and
      may output additional info to the console
      If set, filter capabilities are not checked before filter is built
      (use with caution).

      • globalInfo

        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
      • getCapabilities

        public weka.core.Capabilities getCapabilities()
        Returns the Capabilities of this filter. Derived filters have to override this method to enable capabilities.
        Specified by:
        getCapabilities in interface weka.core.CapabilitiesHandler
        getCapabilities in class weka.filters.Filter
        the capabilities of this object

        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., hasImmediateOutputFormat() returns false, then this method will called from batchFinished() after the call of preprocess(Instances), in which, e.g., statistics for the actual processing step can be gathered.
        Specified by:
        determineOutputFormat in class weka.filters.SimpleStreamFilter
        inputFormat - the input format to base the output format on
        the output format
        Exception - in case the determination goes wrong
      • process

        protected weka.core.Instance process​(weka.core.Instance instance)
                                      throws Exception
        processes the given instance (may change the provided instance) and returns the modified version.
        Specified by:
        process in class weka.filters.SimpleStreamFilter
        instance - the instance to process
        the modified data
        Exception - in case the processing goes wrong
      • getRevision

        public String getRevision()

        getRevision in class weka.filters.Filter
        the revision
