Computes the Tensor Product Pair Kernel (TPPK).
Formally, it computes
It is defined on pairs of inputs and a subkernel
. The subkernel has to be given on initialization. The pairs are specified via indizes (ab)using 2-dimensional integer features.
Its feature space
is the tensor product of the feature spaces of the subkernel
on its input.
It is often used in bioinformatics, e.g., to predict protein-protein interactions.
