Class SimpleSubListKernel<S,T extends java.util.List<S>>

java.lang.Object

fr.lip6.jkernelmachines.kernel.Kernel<T>

fr.lip6.jkernelmachines.kernel.extra.bag.SimpleSubListKernel<S,T>

Type Parameters:

S -

T -

All Implemented Interfaces:

java.io.Serializable

public class SimpleSubListKernel<S,T extends java.util.List<S>>
extends Kernel<T>
implements java.io.Serializable

Kernel on bags of same length.
Let B1 and B2 be bags of elements b1[i] and b2[i], let k(b1[i],b2[i]) be the minor kernel, then K(B1, B2) = sum_{i=n}^{N} k(b1[i],b2[i])
With n and N being the bounds of the sum.
