On Cumulative Tsallis Entropies

open access: yesActa Applicandae Mathematicae, 2023
We investigate the cumulative Tsallis entropy, an information measure recently introduced as a cumulative version of the classical Tsallis differential entropy, which is itself a generalization of the Boltzmann-Gibbs statistics. This functional is here considered as a perturbation of the expected mean residual life via some power weight function.

Tsallis Entropy for Geometry Simplification [PDF]

open access: yesEntropy, 2011
This paper presents a study and a comparison of the use of different information-theoretic measures for polygonal mesh simplification. Generalized measures from Information Theory such as Havrda–Charvát–Tsallis entropy and mutual information have been applied. These measures have been used in the error metric of a surfaces implification algorithm.

Symbolic sequences and Tsallis entropy [PDF]

open access: yesBrazilian Journal of Physics, 2009
We address this work to investigate symbolic sequences with long-range correlations by using computational simulation. We analyze sequences with two, three and four symbols that could be repeated $l$ times, with the probability distribution $p(l)\propto 1/ l^μ$.

Information theoretical properties of Tsallis entropies [PDF]

open access: yes, 2006
A chain rule and a subadditivity for the entropy of type $\beta$, which is one of the nonadditive entropies, were derived by Z.Dar\'oczy. In this paper, we study the further relations among Tsallis type entropies which are typical nonadditive entropies ...

Coherence as entropy increment for Tsallis and Rényi entropies

open access: yesQuantum Information Processing, 2023
Relative entropy of coherence can be written as an entropy difference of the original state and the incoherent state closest to it when measured by relative entropy. The natural question is, if we generalize this situation to Tsallis or Rényi entropies, would it define good coherence measures?

Tsallis Entropy and the Transition to Scaling in Fragmentation [PDF]

open access: yesEntropy, 2000
By using the maximum entropy principle with Tsallis entropy we obtain a fragment size distribution function which undergoes a transition to scaling. This distribution function reduces to those obtained by other authors using Shannon entropy. The treatment is easily generalisable to any process of fractioning with suitable constraints.

Some Properties of Fractal Tsallis Entropy

open access: yesFractal and Fractional, 2023
We introduce fractal Tsallis entropy and show that it satisfies Shannon–Khinchin axioms. Analogously to Tsallis divergence (or Tsallis relative entropy, according to some authors), fractal Tsallis divergence is defined and some properties of it are ...

Is the Tsallis entropy stable? [PDF]

open access: yesEPL (Europhysics Letters), 2009
The question of whether the Tsallis entropy is Lesche-stable is revisited. It is argued that when physical averages are computed with the escort probabilities, the correct application of the concept of Lesche-stability requires use of the escort probabilities.
