A COUNTER-EXAMPLE OF COMPLETE SYSTEMS FORINTUITIONISTIC FUZZY SETS EVENTS [PDF]

Fiabilitate şi Durabilitate, 2015
In this article, starting from the decomposition theoremof a intuitionistic fuzzy setsfrom [6],[2], we give some basic definitions from The level set of Intuitionistic fuzzy sets andwe I will show that thelevel cuts do not form a partition.

Entropy of Fuzzy Partitions and Entropy of Fuzzy Dynamical Systems

Entropy, 2016
In the paper we define three kinds of entropy of a fuzzy dynamical system using different entropies of fuzzy partitions. It is shown that different definitions of the entropy of fuzzy partitions lead to different notions of entropies of fuzzy dynamical ...

Regression Driven F--Transform and Application to Smoothing of Financial Time Series

, 2017
In this paper we propose to extend the definition of fuzzy transform in order to consider an interpolation of models that are richer than the standard fuzzy transform.

Kullback-Leibler Divergence and Mutual Information of Experiments in the Fuzzy Case

Axioms, 2017
The main aim of this contribution is to define the notions of Kullback-Leibler divergence and conditional mutual information in fuzzy probability spaces and to derive the basic properties of the suggested measures.

Probabilistic clustering algorithms for fuzzy rules decomposition [PDF]

, 2007
The fuzzy c-means (FCM) clustering algorithm is the best known and used method in fuzzy clustering and is generally applied to well defined set of data. In this paper a generalized Probabilistic fuzzy c-means (FCM) algorithm is proposed and applied to

A Method Based on Extended Fuzzy Transforms to Approximate Fuzzy Numbers in Mamdani Fuzzy Rule-Based System

Advances in Fuzzy Systems, 2018
We propose a new Mamdani fuzzy rule-based system in which the fuzzy sets in the antecedents and consequents are assigned in a discrete set of points and approximated by using the extended inverse fuzzy transforms, whose components are calculated by ...

R-Norm Entropy and R-Norm Divergence in Fuzzy Probability Spaces

Entropy, 2018
In the presented article, we define the R-norm entropy and the conditional R-norm entropy of partitions of a given fuzzy probability space and study the properties of the suggested entropy measures.

Quantum Equivalence of NC and YM Gauge Theories in 2 D and Matrix Theory [PDF]

, 2007
We construct noncommutative U(1) gauge theory on the fuzzy sphere S^2_N as a unitary 2N x 2N matrix model. In the quantum theory the model is equivalent to a nonabelian U(N) Yang-Mills theory on a 2 dimensional lattice with 2 plaquettes. This equivalence
