Class ListSumKernel
java.lang.Object
org.biojava.stats.svm.NestedKernel
org.biojava.stats.svm.ListSumKernel
- All Implemented Interfaces:
- Serializable, SVMKernel
public class ListSumKernel
- extends NestedKernel
This kernel computes the sum of the dot products between items of two lists
at corresponding indexes. We define k(x, null) to be zero for when list
elements are null.

can actually be arbitrary objects.
