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…
An Analytical Approach to the Jaccard Similarity Index
Gonzalo Travieso, Alexandre Benatti, Luciano da F. Costa
The Jaccard similarity index has often been employed in science and technology as a means to quantify the similarity between two sets. When modified to operate on real-valued value…
Normalization in Proportional Feature Spaces
Alexandre Benatti, Luciano da F. Costa
The subject of features normalization plays an important central role in data representation, characterization, visualization, analysis, comparison, classification, and modeling, a…
Supervised Pattern Recognition Involving Skewed Feature Densities
Alexandre Benatti, Luciano da F. Costa
Pattern recognition constitutes a particularly important task underlying a great deal of scientific and technologica activities. At the same time, pattern recognition involves seve…
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…
Simple Games on Complex Networks
Alexandre Benatti, Luciano da F. Costa
The relationship between topology and dynamics of complex systems has motivated continuing interest from the scientific community. In the present work, we address this interesting…
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…
Node Accessibility Characterization of Radially-Grown Structures
Alexandre Benatti, Roberto M. Cesar, Luciano da F. Costa
Complex systems have motivated continuing interest from the scientific community, leading to new concepts and methods. Growing systems represent a case of particular interest, as t…
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…
Hierarchical Cutting of Complex Networks Performed by Random Walks
Alexandre Benatti, Luciano da F. Costa
Several interesting approaches have been reported in the literature on complex networks, random walks, and hierarchy of graphs. While many of these works perform random walks on st…
Detecting Groups in Directed and Non-Directed Bipartite Networks
Alexandre Benatti, Luciano da F. Costa
Bipartite networks provide an effective resource for representing, characterizing, and modeling several abstract and real-world systems and structures involving binary relations, w…
