Non-Supervised Community Detection and Hierarchical Modularity Estimation in Complex Networks
Alexandre Benatti, Luciano da F. Costa
This work extends to complex networks a recently described methodology (A. Benatti and L. da F Costa, Detecting Hierarchical Clusters and Estimating their Modularity Directly from…
Detecting Hierarchical Clusters and Estimating their Modularity Directly from Dendrograms
Alexandre Benatti, Luciano da F. Costa
Identifying possible clusters in datasets and estimating their hierarchical modularity are central tasks in pattern recognition. In the present work, concepts and methodologies are…
Partially Proportional and Adaptive Similarity Indices
Alexandre Benatti, Luciano da F. Costa
A good deal of science and technology concepts and methods rely on comparing and relating entities in quantitative terms. Among the several possible approaches, similarity indices…
Agglomerative Clustering in Uniform and Proportional Feature Spaces
Alexandre Benatti, Luciano da F. Costa
Pattern comparison represents a fundamental and crucial aspect of scientific modeling, artificial intelligence, and pattern recognition. Three main approaches have typically been a…
Subsuming Complex Networks by Node Walks
Alexandre Benatti, Luciano da F. Costa
The concept of node walk in graphs and complex networks has been addressed, consisting of one or more nodes that move into adjacent nodes, henceforth incorporating the respective c…
Distance-Based Hierarchical Cutting of Complex Networks with Non-Preferential and Preferential Choice of Seeds
Alexandre Benatti, Luciano da F. Costa
Graphs and complex networks can be successively separated into connected components associated to respective seed nodes, therefore establishing a respective hierarchical organizati…
Random Walks Performed by Topologically-Specific Agents on Complex Networks
Alexandre Benatti, Luciano da F. Costa
Random walks by single-node agents have been systematically conducted on various types of complex networks in order to investigate how their topologies can affect the dynamics of t…
Retrieving Hierarchies
Alexandre Benatti, Luciano da F. Costa
Several real-world and abstract structures and systems are characterized by marked hierarchy to the point of being expressed as trees. Because the study of these entities often inv…
Accessibility: A Generalization of the Node Degree (A Tutorial)
Alexandre Benatti, Luciano da F. Costa
Robust and comprehensive characterization of the topological properties of complex networks requires the adoption of several respective measurements, among which the node degree ha…
Contrarian effects and echo chamber formation in opinion dynamics
Henrique Ferraz de Arruda, Alexandre Benatti, Filipi Nascimento Silva +2
The relationship between the topology of a network and specific types of dynamics unfolding in networks constitutes a subject of substantial interest. One type of dynamics that has…
Opinion Diversity and Social Bubbles in Adaptive Sznajd Networks
Alexandre Benatti, Henrique Ferraz de Arruda, Filipi Nascimento Silva +2
Among the several approaches that have been attempted at studying opinion dynamics, the Sznajd model provides some particularly interesting features, such as its simplicity and abi…
