A MATLAB implementation of the propagation graph kernel described in:
Neumann, M. Patricia, N., Garnett, R., and Kersting, K. Efficient Graph Kernels by Randomization. (2013). Machine Learning and Knowledge Discovery in Databases: European Conference (ECML/PKDD 2012), pp. 378--392.
This implementation supports arbitrary user-defined base kernels and transformations.
