Gini-stable Lorenz curves and their relation to the generalised Pareto distribution
Lucio Bertoli-Barsotti, Marek Gagolewski, Grzegorz Siudem +1
We introduce an iterative discrete information production process where we can extend ordered normalised vectors by new elements based on a simple affine transformation, while pres…
Equivalence of inequality indices in the three-dimensional model of informetric impact
Lucio Bertoli-Barsotti, Marek Gagolewski, Grzegorz Siudem +1
Inequality is an inherent part of our lives: we see it in the distribution of incomes, talents, citations, to name a few. However, its intensity varies across environments: there a…
Community detection in complex networks via node similarity, graph representation learning, and hierarchical clustering
Łukasz Brzozowski, Grzegorz Siudem, Marek Gagolewski
Community detection is a critical challenge in analysing real graphs, including social, transportation, citation, cybersecurity, and many other networks. This article proposes thre…
Hierarchical clustering with OWA-based linkages, the Lance-Williams formula, and dendrogram inversions
Marek Gagolewski, Anna Cena, Simon James +1
Agglomerative hierarchical clustering based on Ordered Weighted Averaging (OWA) operators not only generalises the single, complete, and average linkages, but also includes intercl…
Clustering with minimum spanning trees: How good can it be?
Marek Gagolewski, Anna Cena, Maciej Bartoszuk +1
Minimum spanning trees (MSTs) provide a convenient representation of datasets in numerous pattern recognition activities. Moreover, they are relatively fast to compute. In this pap…
