Approximating Network Centrality Measures Using Node Embedding and Machine Learning
Matheus R. F. Mendonça, André M. S. Barreto, Artur Ziviani
Extracting information from real-world large networks is a key challenge nowadays. For instance, computing a node centrality may become unfeasible depending on the intended central…
You Shall not Pass: Avoiding Spurious Paths in Shortest-Path Based Centralities in Multidimensional Complex Networks
Klaus Wehmuth, Artur Ziviani, Leonardo Chinelate Costa +2
In complex network analysis, centralities based on shortest paths, such as betweenness and closeness, are widely used. More recently, many complex systems are being represented by…
Expected Emergence of Algorithmic Information from a Lower Bound for Stationary Prevalence
Felipe S. Abrahão, Klaus Wehmuth, Artur Ziviani
We study emergent information in populations of randomly generated networked computable systems that follow a Susceptible-Infected-Susceptible contagion (or infection) model of imi…
Emergent Open-Endedness from Contagion of the Fittest
Felipe S. Abrahão, Klaus Wehmuth, Artur Ziviani
In this paper, we study emergent irreducible information in populations of randomly generated computable systems that are networked and follow a "Susceptible-Infected-Susceptible"…
A Multilayer and Time-varying Structural Analysis of the Brazilian Air Transportation Network
Bernardo Costa, João Victor Bechara, Klaus Wehmuth +1
This paper provides a multilayer and time-varying structural analysis of one air transportation network, having the Brazilian air transportation network as a case study. Using a si…
Social Events in a Time-Varying Mobile Phone Graph
Carlos Sarraute, Jorge Brea, Javier Burroni +3
The large-scale study of human mobility has been significantly enhanced over the last decade by the massive use of mobile phones in urban populations. Studying the activity of mobi…
Time Centrality in Dynamic Complex Networks
Eduardo Chinelate Costa, Alex Borges Vieira, Klaus Wehmuth +2
There is an ever-increasing interest in investigating dynamics in time-varying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metr…
