Clustering Algorithms: A Comparative Approach
Mayra Z. Rodriguez, Cesar H. Comin, Dalcimar Casanova +4
Many real-world systems can be studied in terms of pattern recognition tasks, so that proper use (and understanding) of machine learning methods in practical applications becomes e…
Segmentation of large images based on super-pixels and community detection in graphs
Oscar A. C. Linares, Glenda Michele Botelho, Francisco Aparecido Rodrigues +1
Image segmentation has many applications which range from machine learning to medical diagnosis. In this paper, we propose a framework for the segmentation of images based on super…
Scaling Properties of Multilayer Random Networks
J. A. Méndez-Bermúdez, Guilherme Ferraz de Arruda, Francisco A. Rodrigues +1
Multilayer networks are widespread in natural and manmade systems. Key properties of these networks are their spectral and eigenfunction characteristics, as they determine the crit…
Rumor propagation with heterogeneous transmission in social networks
Didier A. Vega-Oliveros, Luciano da F. Costa, Francisco A. Rodrigues
Rumor models consider that information transmission occurs with the same probability between each pair of nodes. However, this assumption is not observed in social networks, which…
Unifying Markov Chain Approach for Disease and Rumor Spreading in Complex Networks
Guilherme Ferraz de Arruda, Francisco A. Rodrigues, Pablo Martin Rodriiguez +2
Spreading processes are ubiquitous in natural and artificial systems. They can be studied via a plethora of models, depending on the specific details of the phenomena under study.…
Complex systems: features, similarity and connectivity
Cesar H. Comin, Thomas K. DM. Peron, Filipi N. Silva +3
The increasing interest in complex networks research has been a consequence of several intrinsic features of this area, such as the generality of the approach to represent and mode…
Traveling phase waves in asymmetric networks of noisy chaotic attractors
Thomas K. DM. Peron, Jürgen Kurths, Francisco A. Rodrigues +2
We explore identical Rössler systems organized into two equally-sized groups, among which differing positive and negative in- and out-coupling strengths are allowed. Patterns of di…
Tweaking Synchronisation by Link Addition
Paul Schultz, Thomas Peron, Deniz Eroglu +4
Natural and man-made networks often possess locally tree-like sub-structures. Taking such tree networks as our starting point, we show how the addition of links changes the synchro…
