Mathematical formulation
Computing
Given a set X of n feature vectors of dimension p and a set Y of m feature vectors
, the problem is to compute the sigmoid kernel function
for any pair of input vectors:

where .
Computation method: dense
The method computes the sigmoid kernel function for X and Y matrices.
Programming Interface
