Class ListSumKernel

  • All Implemented Interfaces:
    java.io.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.
