Journal ArticleDOI
Stationarity, non-stationarity and early warning signals in economic networks
TL;DR: In this paper, the authors propose a method to assess whether a real economic network is in a quasi-stationary state by checking the consistency of its structural evolution with appropriate quasi-equilibrium maximum-entropy ensembles of graphs.
Journal ArticleDOI
Tackling information asymmetry in networks: a new entropy-based ranking index
TL;DR: In this article, the authors defined a novel index, InfoRank, intended to measure the quality of the information possessed by each node, computing the Shannon entropy of the ensemble conditioned on the node-specific information.
Journal ArticleDOI
Entropy-based random models for hypergraphs
TL;DR: Fabio Saracco, 2, 3 Giovanni Petri, Renaud Lambiotte, and Tiziano Squartini 6 ‘Enrico Fermi’ Research Center (CREF), Via Panisperna 89A, 00184 Rome (Italy)
Journal ArticleDOI

Ioannis Anagnostou,Tiziano Squartini,Drona Kandhai,Drona Kandhai,Diego Garlaschelli,Diego Garlaschelli +5 more
TL;DR: In this article, a method based on Random Matrix Theory has been developed, which identifies the optimal hierarchical decomposition of the system into internally correlated and mutually anti-correlated communities.

Rewiring World Trade. Part II: A Weighted Network Analysis
TL;DR: In this paper, the authors show that all possible weighted representations of the ITN (directed/undirected, aggregated/ disaggregated) cannot be traced back to local structural properties, which are therefore of limited informativeness.
