Covariance and Correlation Kernels on a Graph in the Generalized Bag-of-Paths Formalism

This work derives closed-form expressions computing the expectation of co-presence and of number of co-occurrences of nodes on paths sampled from a network according to general path weights (a bag of paths). The underlying idea is that two nodes are considered as similar when they often appear toget...
