An Entropy Measure of Non-Stationary Processes

open access: yesEntropy, 2014
Shannon’s source entropy formula is not appropriate to measure the uncertainty of non-stationary processes. In this paper, we propose a new entropy measure for non-stationary processes, which is greater than or equal to Shannon’s source entropy.

Free and classical entropy over the circle. [PDF]

open access: yes, 2007
Relative entropy with respect to normalized arclength measure on the circle is greater than or equal to the negative logarithmic energy (Voiculescu's negative free entropy) and is greater than or equal to the modified relative free entropy.

Adaptive Multiscale Weighted Permutation Entropy for Rolling Bearing Fault Diagnosis

open access: yesIEEE Access, 2020
Fault diagnosis of rolling bearing is of great importance to ensure high reliability and safety in the industrial machinery system. Entropy measures are useful non-linear indicators for time series complexity analysis and have been widely applied in ...

Effect of diversification strategy on firm performance with application of entropy measure in Tehran Stock Exchange [PDF]

open access: yesبررسی‌های حسابداری و حسابرسی, 2015
Firm managers seek a way to improve their firm performance. One way is to use diversification strategy which creates range of business activities for the firms and leads to a better performance.

Interval-valued Possibility Quadripartitioned Single Valued Neutrosophic Soft Sets and some uncertainty based measures on them [PDF]

open access: yesNeutrosophic Sets and Systems, 2016
The theory of quadripartitioned single valued neutrosophic sets was proposed very recently as an extension to the existing theory of single valued neutrosophic sets.

Entropy Measures for Interval Neutrosophic Vague Sets and Their Application in Decision Making [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
Entropy measure is an important tool in measuring uncertain information and plays a vital role in solving Multi Criteria Decision Making (MCDM). At present, various entropy measures in literature are developed to measure the degree of fuzziness. However,

Similarity measure, entropy and distance measure of multiple sets [PDF]

open access: yesJournal of Fuzzy Extension and Applications
A multiple set is an extended version of a fuzzy set that simultaneously addresses an element’s multiplicity and uncertainty. In this paper, we define the approximate equality of multiple sets and study some relevant properties associated with it.

New Entropy, Similarity Measure of Intuitionistic Fuzzy Sets and their Applications in Group Decision Making [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2013
In this paper, we propose a new entropy measure with geometrical interpretation of intuitionistic fuzzy sets. Compared with the entropy measure provided by Szmidt and Kacprzyk, the new entropy formula in this paper can measure both fuzziness and ...

Measure theoretic entropy of random substitution subshifts [PDF]

open access: yes, 2022
Subshifts of deterministic substitutions are ubiquitous objects in dynamical systems and aperiodic order (the mathematical theory of quasicrystals). Two of their most striking features are that they have low complexity (zero topological entropy) and are ...
