org.biojava.stats.svm.PolynomialKernel

All Implemented Interfaces:: Serializable, SVMKernel

public class PolynomialKernel extends NestedKernel

This kernel computes all possible products of order features in feature space. This is done by computing (a.k(i,j) + c)^order for some other kernel k that defines a dot product in some feature space.
