CalculateGraphletKernel: Graphlet kernel

Description

This function calculates a kernel matrix of the graphlet kernel \(K_{GL}\) between unlabeled graphs.

Usage

Arguments

G

a list of igraph graphs

par

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

Value

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