Class ChebyshevDistance

  • All Implemented Interfaces:
    java.io.Serializable, DistanceFunction, OptionHandler, RevisionHandler, TechnicalInformationHandler

    public class ChebyshevDistance
    extends NormalizableDistance
    implements TechnicalInformationHandler
    Implements the Chebyshev distance. The distance between two vectors is the greatest of their differences along any coordinate dimension.

    Valid options are:

     -D
      Turns off the normalization of attribute 
      values in distance calculation.
     -R <col1,col2-col4,...>
      Specifies list of columns to used in the calculation of the 
      distance. 'first' and 'last' are valid indices.
      (default: first-last)
     -V
      Invert matching sense of column indices.
