Characteristic Functions on Graphs: Birds of a Feather, from Statistical Descriptors to Parametric Models

16 May 2020Benedek RozemberczkiRik Sarkar

In this paper, we propose a flexible notion of characteristic functions defined on graph vertices to describe the distribution of vertex features at multiple scales. We introduce FEATHER, a computationally efficient algorithm to calculate a specific variant of these characteristic functions where the probability weights of the characteristic function are defined as the transition probabilities of random walks...
