CalculateConnectedGraphletKernel: Connected graphlet kernel

Description

This function calculates a kernel matrix of the graphlet kernel with connected graphlets \(K_{CGL}\) between unlabeled graphs.

Usage

CalculateConnectedGraphletKernel(G, par)

Arguments

G

a list of igraph graphs

par

the number \(k\) of graphlet nodes (\(k = 3\), 4, or 5 is supported)

Value

a kernel matrix of the connected graphlet kernel \(K_{CGL}\)
