Framework based on complex networks to model and mine patient pathways

Caroline de Oliveira Costa Souza Rosa, Márcia Ito, Alex Borges Vieira +2

The automatic discovery of a model to represent the history of encounters of a group of patients with the healthcare system -- the so-called "pathway of patients" -- is a new field…

Emergence of complex data from simple local rules in a network game

Felipe S. Abrahão, Klaus Wehmuth, Artur Ziviani

As one of the main subjects of investigation in data science, network science has been demonstrated a wide range of applications to real-world networks analysis and modeling. For e…

On the existence of hidden machines in computational time hierarchies

Felipe S. Abrahão, Klaus Wehmuth, Artur Ziviani

Challenging the standard notion of totality in computable functions, one has that, given any sufficiently expressive formal axiomatic system, there are total functions that, althou…

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…
