No-reference image quality assessment using joint multiple edge detection

open access: yes工程科学学报, 2018
Before digital images become available to consumers, they usually undergo several stages of processing, which include acquisition, compression, transmission, and presentation.

On the implementation of maximum entropy sampling with unequal probabilities and without replacement

open access: yesMethodsX
Sampling with maximum entropy offers robustness to statistical inference based on randomization theory. However, there were no comprehensive, practical guides explaining how to implement maximum entropy sampling for finite populations with unequal ...

Bounds for Kullback-Leibler divergence

open access: yesElectronic Journal of Differential Equations, 2016
Entropy, conditional entropy and mutual information for discrete-valued random variables play important roles in the information theory. The purpose of this paper is to present new bounds for relative entropy $D(p||q)$ of two probability distributions

Logical Divergence, Logical Entropy, and Logical Mutual Information in Product MV-Algebras

open access: yesEntropy, 2018
In the paper we propose, using the logical entropy function, a new kind of entropy in product MV-algebras, namely the logical entropy and its conditional version.

Topological Risk-Landscape in Metric-Free Categorical Database

open access: yesIEEE Access
The Entropy-based Categorical Exploratory Data Analysis (CEDA) paradigm is elaborately refined to algorithmically explore the intricate high-order directional associative relational patterns within the heterogeneous chronical disease dynamics captured by
