A New Information-Theoretical Distance Measure for Evaluating Community Detection Algorithms [PDF]

open access: yesJournal of Universal Computer Science, 2019
Community detection is a research area from network science dealing with the investigation of complex networks such as social or biological networks, aiming to identify subgroups (communities) of entities (nodes) that are more closely related to each ...

Joint range of f-divergences [PDF]

open access: yes2010 IEEE International Symposium on Information Theory, 2010
We provide a general method for evaluation of the joint range of f-divergences for two different functions f. Via topological arguments we prove that the joint range for general distributions equals the convex hull of the joint range achieved by the distributions on a two-element set.

A new refinement of Jensen’s inequality with applications in information theory

open access: yesOpen Mathematics, 2020
In this paper, we present a new refinement of Jensen’s inequality with applications in information theory. The refinement of Jensen’s inequality is obtained based on the general functional in the work of Popescu et al.

Refinements of the integral Jensen’s inequality generated by finite or infinite permutations

open access: yesJournal of Inequalities and Applications, 2021
There are a lot of papers dealing with applications of the so-called cyclic refinement of the discrete Jensen’s inequality. A significant generalization of the cyclic refinement, based on combinatorial considerations, has recently been discovered by the ...

Quantum f-divergences via Nussbaum–Szkoła distributions and applications to f-divergence inequalities

open access: yesReviews in Mathematical Physics, 2023
The main result in this paper shows that the quantum [Formula: see text]-divergence of two states is equal to the classical [Formula: see text]-divergence of the corresponding Nussbaum–Szkoła distributions. This provides a general framework for studying certain properties of quantum entropic quantities using the corresponding classical entities.

Distances Based on the Perimeter of the Risk Set of a Testing Problem

open access: yesAustrian Journal of Statistics, 2016
At the core of this paper is a simple geometric object, namely the risk set of a statistical testing problem on the one hand and f-divergences, which were introduced by Csiszár (1963) on the other hand.

On a Generalization of the Jensen–Shannon Divergence and the Jensen–Shannon Centroid

open access: yesEntropy, 2020
The Jensen−Shannon divergence is a renown bounded symmetrization of the Kullback−Leibler divergence which does not require probability densities to have matching supports. In this paper, we introduce a vector-skew generalization of the scalar

Maps on density operators preserving quantum f-divergences [PDF]

open access: yes, 2013
For an arbitrary strictly convex function f defined on the non-negative real line we determine the structure of all transformations on the set of density operators which preserve the quantum f ...
