    public class AttributeSummaryTransferFilter
extends weka.filters.SimpleBatchFilter
implements weka.filters.UnsupervisedFilter
    Filter which trains another filter to summarise a sub-set of the data's attributes. The trained filter should be a supervised or unsupervised attribute filter. Trains the summary filter on a large set of unannotated data so it can be applied to a relatively small set which is annotated with other information.

    Valid options are: 

     -row-finder <value>
  Row finder which selects rows for training the attribute-summarising filter.
  (default: adams.data.weka.rowfinder.NullFinder)
     -column-finder <value>
  Column finder which selects attributes to summarise.
  (default: adams.data.weka.columnfinder.NullFinder)
     -summary-filter <value>
  The filter to use to summarise the attributes.
  (default: weka.filters.unsupervised.attribute.PrincipalComponentsJ -R 0.95 -A 5 -M -1)
     -preserve-id-column <value>
  Whether the first column of the test data should be treated as a sample ID and kept in the first position of the output.
  (default: off)
     -class-name <value>
  The name of the attribute to treat as the class for supervised filters.
  (default: )
     -keep-supervised-class <value>
  Whether the class value for supervised filters should be kept in the resultant dataset or discarded.
  (default: off)
     -output-debug-info
  If set, filter is run in debug mode and
  may output additional info to the console
     -do-not-check-capabilities
  If set, filter capabilities are not checked before filter is built
  (use with caution).
