NetLSD

NetLSD is a family of spectral graph descriptros. Given a graph, NetLSD computes a low-dimensional vector representation that can be used for different tasks.

Quick start

import netlsd
import networkx as nx

g = nx.erdos_renyi_graph(100, 0.01) # create a random graph with 100 nodes
descriptor = netlsd.heat(g) # compute the signature

That's it! Then, signatures of two graphs can be compared easily. NetLSD supports networkx, graph_tool, and igraph packages natively.

import netlsd
import numpy as np

distance = netlsd.compare(desc1, desc2) # compare the signatures using l2 distance
distance = np.linalg.norm(desc1 - desc2) # equivalent

For more advanced usage, check out online documentation.
