ListSumKernel (biojava-legacy 1.9.5 API)

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.
