Class RELAGGS

  • All Implemented Interfaces:
    java.io.Serializable, CapabilitiesHandler, OptionHandler, RevisionHandler, TechnicalInformationHandler
    public class RELAGGS
extends SimpleBatchFilter
implements TechnicalInformationHandler
    A propositionalization filter inspired by the RELAGGS algorithm.
    It processes all relational attributes that fall into the user defined range (all others are skipped, i.e., not added to the output). Currently, the filter only processes one level of nesting.
    The class attribute is not touched.

    Valid options are: 

     -D
  Turns on output of debugging information.
     -R <index1,index2-index4,...>
  Specify list of string attributes to convert to words.
  (default: select all relational attributes)
     -V
  Inverts the matching sense of the selection.
     -C <num>
  Max. cardinality of nominal attributes. If a nominal attribute
  has more values than this upper limit, then it will be skipped.
