A Novel Hyperbolic Fuzzy Entropy Measure for Discrimination and Taxonomy of Transformer Winding Faults

IEEE Transactions on Instrumentation and Measurement, 2022
During operation, power transformers are subjected to a variety of electrical and mechanical stresses, which can result in winding faults. The most common defects in transformers are axial displacement, radial deformation, and short circuits in the ...

Fuzzy Dispersion Entropy: A Nonlinear Measure for Signal Analysis

IEEE transactions on fuzzy systems, 2022
Entropy is a powerful tool for nonlinear analysis of time series. We have recently introduced dispersion entropy (DispEn), which has widely drawn attention from researchers in a variety of settings in data analysis.

Multiscale Diversity Entropy: A Novel Dynamical Measure for Fault Diagnosis of Rotating Machinery

IEEE Transactions on Industrial Informatics, 2021
In this article, a fault diagnosis scheme based on multiscale diversity entropy (MDE) and extreme learning machine (ELM) is presented. First, a novel entropy method called diversity entropy (DE) is proposed to quantify the dynamical complexity.

Measurement of granular entropy

Physical Review E, 2009
Recently, Dean and Lefèvre [Phys. Rev. Lett. 90, 198301 (2003)] developed a method for testing the statistical mechanical theory of granular packings proposed by Edwards and co-workers [Physica A 157, 1080 (1989); Phys. Rev. E 58, 4758 (1998)]. The method relies on the prediction that the ratio of two overlapping volume histograms should be exponential

Optimized Fuzzy Slope Entropy: A Complexity Measure for Nonlinear Time Series

IEEE Transactions on Instrumentation and Measurement
Entropy has long been a subject that has attracted researchers from a diverse range of fields, including healthcare, finance, and fault detection. Slope entropy (SE) has recently been proposed as a new approach to address the shortcomings of permutation ...

Relevant Entropy vs . Measurement Entropy

Europhysics Letters (EPL), 1986
We compare two different entropies which can be assigned to measurements of an observable A in a state ρ, and comment upon their physical meaning.

THE MINIMAL κ-ENTROPY MARTINGALE MEASURE [PDF]

open access: possibleInternational Journal of Theoretical and Applied Finance, 2012
We introduce the notion of κ-entropy (κ ∈ ℝ, |κ| ≤ 1), starting from Kaniadakis' (2001, 2002, 2005) one-parameter deformation of the ordinary exponential function. The κ-entropy is in duality with a new class of utility functions which are close to the exponential utility functions, for small values of wealth, and to the power law utility functions ...

GENERAL ENTROPY OF GENERAL MEASURES

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2002
The concept of entropy is an important part of the theory of additive measures. In this paper, a definition of entropy is introduced for general (not necessarily additive) measures as the infinum of the Shannon entropies of "subordinate" additive measures. Several properties of the general entropy are discussed and proved.

Phase entropy: a new complexity measure for heart rate variability

Physiological Measurement, 2019
Objective: Information entropy is generally employed for analysing the complexity of physiological signals. However, most definitions of entropy estimate the degree of compressibility and thus quantify the randomness.
