  1. (, Information and inference)
    To characterize the location (mean, median) of a set of graphs, one needs a notion of centrality that has been adapted to metric spaces. A standard approach is to consider the Fréchet mean. In practice, computing the Fréchet mean for sets of large graphs presents many computational issues. In this work, we suggest a method that may be used to compute the Fréchet mean for sets of graphs which is metric independent. We show that the technique proposed can be used to determine the Fréchet mean when considering the Hamming distance or a distance defined by the difference between the spectra of the adjacency matrices of the graphs.
