## weka.classifiers.mi.supportVector
Class MIPolyKernel

    java.lang.Object
      weka.classifiers.functions.supportVector.Kernel
          weka.classifiers.functions.supportVector.CachedKernel
              weka.classifiers.functions.supportVector.PolyKernel
                  weka.classifiers.mi.supportVector.MIPolyKernel

All Implemented Interfaces:
  java.io.Serializable, CapabilitiesHandler, MultiInstanceCapabilitiesHandler, OptionHandler, RevisionHandler

    public class MIPolyKernel

extends PolyKernel
implements MultiInstanceCapabilitiesHandler

The polynomial kernel : K(x, y) = <x, y>^p or K(x, y) = (<x, y>+1)^p

Valid options are:

     -D
      Enables debugging output (if available) to be printed.
      (default: off)

     -no-checks
      Turns off all checks - use with caution!
      (default: checks on)

     -C <num>
      The size of the cache (a prime number), 0 for full cache and
      -1 to turn it off.
      (default: 250007)

     -E <num>
      The Exponent to use.
      (default: 1.0)

     -L
      Use lower-order terms.
      (default: no)
