Generative Hypergraph Models and Spectral Embedding
Xue Gong, Desmond J. Higham, Konstantinos Zygalakis
Many complex systems involve interactions between more than two agents. Hypergraphs capture these higher-order interactions through hyperedges that may link more than two nodes. We…
A Hierarchy of Network Models Giving Bistability Under Triadic Closure
Stefano Di Giovacchino, Desmond J. Higham, Konstantinos C. Zygalakis
Triadic closure describes the tendency for new friendships to form between individuals who already have friends in common. It has been argued heuristically that the triadic closure…
Directed Network Laplacians and Random Graph Models
Xue Gong, Desmond John Higham, Konstantinos Zygalakis
We consider spectral methods that uncover hidden structures in directed networks. We establish and exploit connections between node reordering via (a) minimizing an objective funct…
