All Implemented Interfaces:

java.io.Serializable, weka.core.CapabilitiesHandler, weka.core.MultiInstanceCapabilitiesHandler, weka.core.OptionHandler, weka.core.RevisionHandler

public class MIPolyKernel
extends weka.classifiers.functions.supportVector.PolyKernel
implements weka.core.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)

 -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)
