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
The size of the cache (a prime number), 0 for full cache and
-1 to turn it off.
(default: 250007)
-E
The Exponent to use.
(default: 1.0)
-L
Use lower-order terms.
(default: no)
