public class MIRBFKernel
The RBF kernel. K(x, y) = e^-(gamma * <x-y, x-y>^2)
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). (default: 250007)
-G <num> The Gamma parameter. (default: 0.01)
