pygk is a python implementation (under development) of a subset of graph kernels and other related methods based on MATLAB codes by Nino Shervashidze.

Following graph kernels are implemented:

• Shortest path kernel (for both unlabeled and discretely-labeled graph)
• Random walk kernel (for both unlabeled and discretely-labeled graph)
• Weisfeiler-Lehman kernel (for discretely-labeled graph)
• 3-graphlet kernel (for discretely-labeled graph)
• (3,4,5)-graphlet kernel (for unlabeled graph)
