Dealing with non-metric dissimilarities in fuzzy central clustering algorithms [PDF]

open access: yes, 2008
Clustering is the problem of grouping objects on the basis of a similarity measure among them. Relational clustering methods can be employed when a feature-based representation of the objects is not available, and their description is given in terms of ...

Fuzzy probability space and extension theorem

open access: yesJournal of Mathematical Analysis and Applications, 1986
This paper deals with fundamental mathematical theory of fuzzy probability. As classical measure theory, fuzzy algebra, fuzzy \(\sigma\)- algebra and fuzzy probability, whose \(\sigma\)-additivity is characterized by the countable uncoincident fuzzy events and the operation \(\oplus\), are introduced.

Some New Aspects in the Intuitionistic Fuzzy and Neutrosophic Fixed Point Theory

open access: yesJournal of Function Spaces, 2022
In this manuscript, we use the concepts of continuous t-norms and continuous t-conorms to introduce some definitions, in which intuitionistic fuzzy rectangular metric spaces, intuitionistic fuzzy rectangular metric-like spaces, intuitionistic fuzzy ...

A Single-Valued Extended Hesitant Fuzzy Score-Based Technique for Probabilistic Hesitant Fuzzy Multiple Criteria Decision-Making

open access: yesComplexity, 2021
The probabilistic hesitant fuzzy set (PHFS) is a worthwhile extension of the hesitant fuzzy set (HFS) which allows people to improve their quantitative assessment with the corresponding probability.

Fuzzy stochastic damage mechanics (FSDM) based on fuzzy auto-adaptive control theory

open access: yesWater Science and Engineering, 2012
In order to fully interpret and describe damage mechanics, the origin and development of fuzzy stochastic damage mechanics were introduced based on the analysis of the harmony of damage, probability, and fuzzy membership in the interval of [0,1].

Random Fuzzy Clustering Granular Hyperplane Classifier

open access: yesIEEE Access, 2020
Granular computing is a method of studying human intelligent information processing, which has advantage of knowledge discovery. In this paper, we convert a classification problem of sample space into a classification problem of fuzzy clustering granular

An Uniformly Minimum Variance Unbiased Point Estimator Using Fuzzy Observations

open access: yesAustrian Journal of Statistics, 2016
This paper proposes a new method for uniformly minimum variance unbiased fuzzy point estimation. For this purpose we make use of a uniformly minimum variance unbiased estimator and we develop this new method for a fuzzy random sample ~X1,...,~Xn  is ...

Logical Entropy of Fuzzy Dynamical Systems

open access: yesEntropy, 2016
Recently the logical entropy was suggested by D. Ellerman (2013) as a new information measure. The present paper deals with studying logical entropy and logical mutual information and their properties in a fuzzy probability space.

Approximating a similarity matrix by a latent class model: A reappraisal of additive fuzzy clustering

open access: yes, 2009
Let Q be a given n×n square symmetric matrix of nonnegative elements between 0 and 1, similarities. Fuzzy clustering results in fuzzy assignment of individuals to K clusters.
