Samplers and Extractors for Unbounded Functions [PDF]

open access: yes, 2019
Blasiok (SODA\u2718) recently introduced the notion of a subgaussian sampler, defined as an averaging sampler for approximating the mean of functions f from {0,1}^m to the real numbers such that f(U_m) has subgaussian tails, and asked for explicit ...

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

Estimation of different entropies via Abel–Gontscharoff Green functions and Fink’s identity using Jensen type functionals [PDF]

open access: yesArab Journal of Mathematical Sciences, 2020
In this work, we estimated the different entropies like Shannon entropy, Rényi divergences, Csiszár divergence by using Jensen’s type functionals. The Zipf’s–Mandelbrot law and hybrid Zipf’s–Mandelbrot law are used to estimate the Shannon entropy.

RETRACTED ARTICLE: Generalization of the Levinson inequality with applications to information theory

open access: yesJournal of Inequalities and Applications, 2019
In the presented paper, Levinson’s inequality for 3-convex function is generalized by using two Green’s functions. Čebyšev, Grüss, and Ostrowski-type new bounds are found for the functionals involving data points of two types.

Spacecraft Anomaly Recognition Based on Morphological Variational Mode Decomposition and JRD [PDF]

open access: yesXibei Gongye Daxue Xuebao, 2018
Considering the difficulty in identifying the in-orbital spacecraft weak anomaly, a spacecraft anomaly state recognition method based on Morphological variational mode decomposition and JRD distance is proposed.

Topologically Protected Negative Entanglement. [PDF]

open access: yesAdv Sci (Weinh)
It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.

On some entropy functionals derived from R\'enyi information divergence [PDF]

open access: yes, 2008
We consider the maximum entropy problems associated with R\'enyi $Q$-entropy, subject to two kinds of constraints on expected values. The constraints considered are a constraint on the standard expectation, and a constraint on the generalized expectation

Generalization of the Levinson inequality with applications to information theory

open access: yesJournal of Inequalities and Applications, 2019
In the presented paper, Levinson’s inequality for the 3-convex function is generalized by using two Green functions. Čebyšev-, Grüss- and Ostrowski-type new bounds are found for the functionals involving data points of two types.

Constraining quantum fields using modular theory

open access: yesJournal of High Energy Physics, 2019
Tomita-Takesaki modular theory provides a set of algebraic tools in quantum field theory that is suitable for the study of the information-theoretic properties of states.

Association of Jensen’s inequality for s-convex function with Csiszár divergence

open access: yesJournal of Inequalities and Applications, 2019
In the article, we establish an inequality for Csiszár divergence associated with s-convex functions, present several inequalities for Kullback–Leibler, Renyi, Hellinger, Chi-square, Jeffery’s, and variational distance divergences by using particular s ...
