Versatile linkage: a family of space-conserving strategies for agglomerative hierarchical clustering
Alberto Fernández, Sergio Gómez
Agglomerative hierarchical clustering can be implemented with several strategies that differ in the way elements of a collection are grouped together to build a hierarchy of cluste…
MultiDendrograms: Variable-Group Agglomerative Hierarchical Clusterings
Sergio Gomez, Justo Montiel, David Torres +1
MultiDendrograms is a Java-written application that computes agglomerative hierarchical clusterings of data. Starting from a distances (or weights) matrix, MultiDendrograms is able…
Motif-based communities in complex networks
Alex Arenas, Alberto Fernandez, Santo Fortunato +1
Community definitions usually focus on edges, inside and between the communities. However, the high density of edges within a community determines correlations between nodes going…
Analysis of the structure of complex networks at different resolution levels
Alex Arenas, Alberto Fernandez, Sergio Gomez
Modular structure is ubiquitous in real-world complex networks, and its detection is important because it gives insights in the structure-functionality Modular structure is ubiquit…
Solving non-uniqueness in agglomerative hierarchical clustering using multidendrograms
Alberto Fernandez, Sergio Gomez
In agglomerative hierarchical clustering, pair-group methods suffer from a problem of non-uniqueness when two or more distances between different clusters coincide during the amalg…
Portfolio selection using neural networks
Alberto Fernandez, Sergio Gomez
In this paper we apply a heuristic method based on artificial neural networks in order to trace out the efficient frontier associated to the portfolio selection problem. We conside…
