We report a surprising, persistent pattern in an important class of large sparse social graphs, which we term EigenSpokes. We focus on large Mobile Call graphs, spanning hundreds of thousands of nodes and edges, and find that the singular vectors of these graphs exhibit a striking EigenSpokes pattern wherein, when plotted against each other, they have clear, separate lines that often neatly align along specific axes (hence the term "spokes"). We show this phenomenon to be persistent across both… CONTINUE READING
