PolynomialKernel (biojava-legacy 1.9.5 API)

java.lang.Object
- org.biojava.stats.svm.NestedKernel
- - 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.
