CalculateVertexVertexEdgeHistKernelR Documentation

Linear kernel combination of vertex label histograms and vertex-edge label histograms

Description

This function calculates a kernel matrix of the linear kernel combination K_H of vertex label histograms K_VH and vertex-edge label histograms K_VEH.

Usage

CalculateVertexVertexEdgeHistKernel(G, par)

Arguments

G

a list of igraph graphs

par

a coefficient lambda, with which the resulting kernel is given as K_VH + lambda K_VEH

Value

a kernel matrix that is equivalent to K_VH + lambda K_VEH
