ENTROPY (RÉNYI’S AND OTHERS)
Entropy is one of the characteristics of a random variable. Some generalized original Shannon entropies such as Rényi’s or Tsalli’s entropy are shown in the work. Other possibilities of generalization are ...

On generalized entropies, Bayesian decisions and statistical diversity
Generalized entropies are introduced as maximal generalized informations achieved by a direct observation of data sources. Prominent examples are the Shannon and quadratic entropies. Their mutual anisotony and rela...

Generalized Entropies: A Fancy Misconception Or Some New Physical Insight?
of "generalized entropies" in "nonextensive statistical thermodynamics" by Tsallis et al. Our for these"generalized entropies" are incorrect. Consequently, rather than bringing some principally new physical insigh...

Generalized statistics: yet another generalization
We provide a unifying axiomatics for Renyi's entropy and non-extensive entropy of Tsallis. It is shown that the resulting entropy coincides with Csiszar's measure of directed divergence known from communication theory....

On relations between informations, entropies and Bayesian decisions
A class of power entropies is introduced which are concave functions of distributions for positive powers and convex for negative powers. It is shown that the maximal generalized informations are often convex power entropies

On the Relation between Generalized Entropy and the Bayes Decision Error
We deal with the relation between generalized entropies (f-entropies and the lower bound for the Bayes error under given entropy. It can be applied to any strictly concave f-entropy and used to evaluate it...

Conditional Entropy of DNA
the aim of our paper is make survey of conditional entropy of DNA and compare it to conditional entropy of human languages. We have not been able to prove the hypothesis that conditional entropy of human languages and DNA a...
