GraphKernel (class)

Documentation for the graph-kernel generic wrapper.

The GraphKernel Decorator

A specification follows for GraphKernel where each of the supported kernel is presented with whether it utilizes information from node-labels, edge-labels, node-attributes, edge-attributes inside the kernel calculation.

where [, ] denounce the default value and the kernel-names and arguments are as given in the __init__ of the GraphKernel object and base_kernel signifies means that given input with this type of meta-information the behavior of the kernel should only depend on the behavior of the base kernel to this type of meta-information.
