Inference of Edge Correlations in Multilayer Networks

no code implementations11 Aug 2019 A. Roxana Pamfil, Sam D. Howison, Mason A. Porter

A common (but {potentially} inadequate) assumption of these models is the sampling of edges in different layers independently, conditioned on the community labels of the nodes.

Tunable Eigenvector-Based Centralities for Multiplex and Temporal Networks

2 code implementations3 Apr 2019 Dane Taylor, Mason A. Porter, Peter J. Mucha

Characterizing the importances of nodes in social, biological, information and technological networks is a core topic for the network-science and data-science communities.
