Hybrid MCDM Based on VIKOR and Cross Entropy under Rough Neutrosophic Set Theory

open access: yesMathematics, 2021
Problems in real life usually involve uncertain, inconsistent and incomplete information. An example of such problems is strategic decision making with respect to remediation planning of historic pedestrian bridges.

Streaming generalized cross entropy [PDF]

open access: yesSoft Computing, 2019
We propose a new method to combine adaptive processes with a class of entropy estimators for the case of streams of data. Starting from a first estimation obtained from a batch of initial data, model parameters are estimated at each step by combining the prior knowledge with the new observation (or a block of observations).

Detection of Coronary Artery Disease Using Multi-Domain Feature Fusion of Multi-Channel Heart Sound Signals

open access: yesEntropy, 2021
Heart sound signals reflect valuable information about heart condition. Previous studies have suggested that the information contained in single-channel heart sound signals can be used to detect coronary artery disease (CAD). But accuracy based on single-

Optimal Power Flow Using Improved Cross-Entropy Method

open access: yesEnergies, 2023
An improved cross-entropy (CE) method assisted with a chaotic operator (CGSCE) is presented for solving the optimal power flow (OPF) problem. The introduction of the chaotic operator helps to enhance the exploration capability of the popular cross ...

Bivariate Entropy Analysis of Electrocardiographic RR–QT Time Series

open access: yesEntropy, 2020
QT interval variability (QTV) and heart rate variability (HRV) are both accepted biomarkers for cardiovascular events. QTV characterizes the variations in ventricular depolarization and repolarization. It is a predominant element of HRV.

Entropy, Duality, and Cross Diffusion [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2014
This paper is devoted to the use of the entropy and duality methods for the existence theory of reaction-cross diffusion systems consisting of two equations, in any dimension of space. Those systems appear in population dynamics when the diffusion rates of individuals of two species depend on the concentration of individuals of the same species (self ...

A Bregman-Split-Based Compressive Sensing Method for Dynamic Harmonic Estimation

open access: yesEntropy, 2022
In order to overcome the spectral interference of the conventional Fourier transform in the International Electrotechnical Commission framework, this paper introduces a Bregman-split-based compressive sensing (BSCS) method to estimate the Taylor–Fourier ...

Neutrosophic cross entropy-based discrimination of antioxidant potential and polyphenolic contents of Arisaema tortuosum [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
The study presents the utilization of an innovative neutrosophic cross entropy-based technique for the discrimination of the antioxidant potential of Arisaema tortuosum leaf extract based on polyphenolic content. The effect of three extraction techniques,

Learning Sequential General Pattern and Dependency via Hybrid Neural Model for Session-Based Recommendation

open access: yesIEEE Access, 2022
Recent study shows that recommendation system not only relys on user’s static preference, but also dynamic preference. Consequently, it leads to the emergence of session-based recommendation.
