two-dimensional fuzzy Renyi entropy, is defined and employed to compute the fuzzy entropy of object and background respectively, and thus the image is segmented following maximum entropy principle.Compared with other typical methods by experiments, the presented method is verifiedto be more effective and robust. Keywords: Infrared electric ... The Fresnel equation for reflectivity at the interface between two mediums with different refractive indices was used to calculate the directional reflectivity, R. Various liquid samples from 1.3325 to 1.4657 refractive indices units were used.

# loss function: Binary Cross-entropy and optimizer: Adam model.compile(loss='binary_crossentropy', optimizer='adam').An entropy on IFS(X) is a real-valued functional E : IFS(X) → [0, 1] 1], satisfying the following axiomatic requirements: • =E(A) 0 iff A is a crisp set; that is A i = A i =µ (x ) 0 or µ (x ) 1 for all i ∈x X Abstract: The entropy of an intuitionistic fuzzy set (IFS) is a measure of uncertainty related to the The axioms for a new entropy of an IFS are defined and a mathematical expression/formula of the...This paper deals with the divergence of fuzzy variables from a priori one. Within the framework of credibility theory, a fuzzy cross-entropy is defined to measure the divergence, and some mathematical properties are investigated.

approach using fuzzy gain ratio for medical dataset. The feature selection method based on the fuzzy gain ratio of fuzzy rough set theory performed better than other approaches (Maqsood et al., 2014). Sudha and Valarmathi, 2013) mentioned that a feature reduction approach based on quick reduct, entropy measure and rough set approaches have Calculate the Shannon entropy for an input string. See also http://blog.dkbza.org/2007/05/scanning-data-for-entropy-anomalies.html ...the interval-valued intuitionistic fuzzy entropy is presented and the corresponding formula is New axiomatic entropy definition is proposed for the sake of more reasonable depiction of the fuzziness...Feb 12, 2016 · The entropy of the entire image is then given by: In the equation above, the summation is taken over all of the possible gray levels, and N is the total number of pixels in the image. The algorithm operates by finding the threshold gray level that minimizes the entropy of the fuzziness measure. Fuzzy Time Series Forecasting Based On K-Means Clustering. Zhiqiang Zhang, Qiong Zhu. Open Journal of Applied Sciences Vol.2 No.4B，January 15, 2013 DOI: 10.4236/ojapps.2012.24B024 2,919 Downloads 5,135 Views Citations. A New Bandwidth Interval Based Forecasting Method for Enrollments Using Fuzzy Time Series The aim of this paper is to extend the notion of topological entropy for fuzzy semidynamical systems created by a self-map on a fuzzy metric space. We show that if a metric space has two uniformly equivalent metrics, then fuzzy entropy is a constant up to these two metrics. In statistics, an approximate entropy (ApEn) is a technique used to quantify the amount of regularity and the unpredictability of fluctuations over time-series data. For example, there are two series of data: series 1: (10,20,10,20,10,20,10,20,10,20,10,20...), which alternates 10 and 20.

the concept of fuzzy entropy [8] have been popular in recent years. Fuzzy entropy is an extension of Shannon’s definition and its meaning is quite different from the classical Shannon entropy due to the fact that fuzzy entropy contains vagueness and ambiguity uncertainties, while Shannon entropy contains randomness uncertainty [9]. Shannon Entropy The Shannon entropy equation provides a way to estimate the average minimum number of bits needed to encode a string of symbols, based on the frequency of the symbols. In the Shannon entropy equation, p i is the probability of a given symbol. To calculate log 2 from another log base (e.g., log 10 or log e): Entanglement entropy on the fuzzy sphere. Joanna L. Karczmarek and Philippe Sabella-Garnier Department of Physics and Astronomy, University of British Columbia Recall the Wigner formula,7.Mostly the existing study on intuitionistic fuzzy entropy formula is based on Definitions 1and 2, among which Szmidt and Kacprzyk combined using the geometric meaning of intuitionistic fuzzy sets to give an intuitionistic fuzzy entropy formula as follows:where,, andAnd which is called the maximum potential. the fuzzy entropy should comply and they deﬁned the entropy of a fuzzy set based on Shannon’s function. Yager [33] presented an entropy measure to view the fuzziness degree of the fuzzy set in terms of a lack of distinction between the fuzzy set and its complement. Other entropies for fuzzy sets with different points of views can be found ... The fuzzy entropy value depends less on the record length, so N is set to 4096 in this paper. The width of the fuzzy function boundary is decided by the parameter r while the boundary gradient is determined by the parameter n . 1520-1532 2020 28 IEEE ACM Trans. Audio Speech Lang. Process. https://doi.org/10.1109/TASLP.2020.2994436 db/journals/taslp/taslp28.html#TangWY20 Li Yang Qiuzhuang Sun ... This method is based on the use of the associated power flow equation, each power term being identified by using a global statistical energy analysis of the fuzzy structure (master structure with its fuzzy substructures). Identification is then carried out by solving a nonlinear constrained optimization problem.

In the present literature on fuzzy sets and fuzzy information, there is much confusion between entropies One must carefully distinguish between index of fuzziness, uncertainty of fuzziness and...This paper presents two variants of pentavalued representation for neutrosophic entropy. The first is an extension of Kaufman's formula and the second is an extension of Kosko's formula. 3.2 Fuzzy Shannon’s entropy based on α- level sets Hosseinzadeh, Lotfi and Fallahnejad (2010) extend the Shannon entropy for the imprecise data, especially interval and fuzzy data cases. In this paper we obtain the weights of criteria based on their method. The steps of fuzzy Shannon’s Entropy explained as follow (Hosseinzadeh et al., 2010): See-and-Avoid Quadcopter using Fuzzy Control Optimized by Cross-Entropy Miguel A. Olivares-Mendez Luis Mejias Pascual Campoy and Ignacio Mellado-Bataller Abstract—In this work we present an optimized fuzzy visual servoing system for obstacle avoidance using an unmanned aerial vehicle.

intuitionistic fuzzy information, imprecise fuzzy information, fuzzy partitions. 1 Introduction The Shannon entropy [12] plays an important role in the information uncer-tainty computing. Thus, if the information vector is deﬁned by formula: DOI: 10.13140/RG.2.2.15428.94085 triangular fuzzy numbers, and the weights of each criterion are found by entropy. According to the concept of TOPSIS, a closeness coefficient is defined to determine the raking by calculating the distance of both the fuzzy positive-ideal solution and fuzzy negative-ideal solution. The proposed Fuzzy entropy: a brief survey Abstract: This paper presents a survey about different types of fuzzy information measures. A number of schemes have been proposed to combine the fuzzy set theory and its application to the entropy concept as a fuzzy information measurements.
