Geometry Induced by a Generalization of Rényi Divergence

open access: yesEntropy, 2016
In this paper, we propose a generalization of Rényi divergence, and then we investigate its induced geometry. This generalization is given in terms of a φ-function, the same function that is used in the definition of non-parametric φ-families.

Rényi Entropy in Statistical Mechanics

open access: yesEntropy, 2022
Rényi entropy was originally introduced in the field of information theory as a parametric relaxation of Shannon (in physics, Boltzmann–Gibbs) entropy. This has also fuelled different attempts to generalise statistical mechanics, although mostly skipping

Rényi Divergences, Bures Geometry and Quantum Statistical Thermodynamics

open access: yesEntropy, 2016
The Bures geometry of quantum statistical thermodynamics at thermal equilibrium is investigated by introducing the connections between the Bures angle and the Rényi 1/2-divergence.

The Rényi divergence enables accurate and precise cluster analysis for localization microscopy. [PDF]

open access: yesBioinformatics, 2018
Motivation Clustering analysis is a key technique for quantitatively characterizing structures in localization microscopy images. To build up accurate information about biological structures, it is critical that the quantification is ...

Refined Young Inequality and Its Application to Divergences

open access: yesEntropy, 2021
We give bounds on the difference between the weighted arithmetic mean and the weighted geometric mean. These imply refined Young inequalities and the reverses of the Young inequality. We also studied some properties on the difference between the weighted

Fractal Divergences of Generalized Jacobi Polynomials

open access: yesMathematics, 2023
The notion of entropy (including macro state entropy and information entropy) is used, among others, to define the fractal dimension. Rényi entropy constitutes the basis for the generalized correlation dimension of multifractals.

Conditional Rényi Divergences and Horse Betting

open access: yesEntropy, 2020
Motivated by a horse betting problem, a new conditional Rényi divergence is introduced. It is compared with the conditional Rényi divergences that appear in the definitions of the dependence measures by Csiszár and Sibson, and the ...

Geometric Rényi Divergence and its Applications in Quantum Channel Capacities

open access: yes, 2021
Having a distance measure between quantum states satisfying the right properties is of fundamental importance in all areas of quantum information. In this work, we present a systematic study of the geometric Rényi divergence (GRD), also known as the ...

On Representations of Divergence Measures and Related Quantities in Exponential Families

open access: yesEntropy, 2021
Within exponential families, which may consist of multi-parameter and multivariate distributions, a variety of divergence measures, such as the Kullback–Leibler divergence, the Cressie–Read divergence, the Rényi divergence, and the Hellinger metric, can ...

A Rényi quantum null energy condition: proof for free field theories

open access: yesJournal of High Energy Physics, 2021
The Quantum Null Energy Condition (QNEC) is a lower bound on the stress-energy tensor in quantum field theory that has been proved quite generally.
