This zip (560 KB) archive contains Matlab scripts to compute various graph kernels for graphs with unlabeled or categorically labeled nodes, such as the random walk, shortest path, graphlet, several instances of Weisfeiler-Lehman or other subtree kernels. For a more detailed list of available kernels please consult the README in the archive.
You can also download the graph data sets MUTAG, NCI1, NCI109, ENZYMES, and D&D (all in Matlab format) as a zip (10 MB) archive. This archive also contains a README describing the data sets and explaining their usage.
