Fuzzy Type Relations and Transformation Operators Defined by Monads

open access: yesInternational Journal of Computational Intelligence Systems, 2020
Using the theory of monads in categories and the theory of monadic relations, the concept of general transformation operator defined by a monadic relation is introduced.

Data granulation by the principles of uncertainty [PDF]

open access: yes, 2015
Researches in granular modeling produced a variety of mathematical models, such as intervals, (higher-order) fuzzy sets, rough sets, and shadowed sets, which are all suitable to characterize the so-called information granules.

The Parameter Reduction of Fuzzy Soft Sets Based on Soft Fuzzy Rough Sets

open access: yesAdvances in Fuzzy Systems, 2013
Fuzzy set theory, rough set theory, and soft set theory are three effective mathematical tools for dealing with uncertainties and have many wide applications both in theory and practise. Meng et al.

Interval-valued and intuitionistic fuzzy mathematical morphologies as special cases of L-fuzzy mathematical morphology [PDF]

open access: yes, 2011
Mathematical morphology (MM) offers a wide range of tools for image processing and computer vision. MM was originally conceived for the processing of binary images and later extended to gray-scale morphology.

A Deep Convolutional Neural Network With Fuzzy Rough Sets for FER

open access: yesIEEE Access, 2020
Existing facial emotion recognition methods do not have high accuracy and are not sufficient practical in real-time applications. We introduce type 2 fuzzy rough sets to develop a Type 2 Fuzzy Rough Convolutional Neural Network, as type 2 fuzzy rough ...

Gradual Sets: An Approach to Fuzzy Sets

open access: yesAdvances in Fuzzy Systems, 2023
In the fuzzy theory of sets and groups, the use of α-levels is a standard to translate problems from the fuzzy to the crisp framework. Using strong α-levels, it is possible to establish a one to one correspondence which makes possible doubly, a gradual ...

An independence property for general information [PDF]

open access: yes, 2016
The aim of this paper was a generalization of independence propery proposed by Kampè de Fèriet and Forte in Information Theory withou probability, called "general infromation".

Formalization of Fuzzy Control in Possibility Theory via Rule Extraction

open access: yesIEEE Access, 2019
Possibility system has been recently recognized as a potential foundational theory for fuzzy set theory though the concept of possibility originated from the membership function of fuzzy sets. As an application of fuzzy set theory, fuzzy control has been

Type-2 Fuzzy Soft Sets and Their Applications in Decision Making

open access: yesJournal of Applied Mathematics, 2012
Molodtsov introduced the theory of soft sets, which can be used as a general mathematical tool for dealing with uncertainty. This paper aims to introduce the concept of the type-2 fuzzy soft set by integrating the type-2 fuzzy set theory and the soft set

On the Neutrosophic, Pythagorean and Some Other Novel Fuzzy Sets Theories Used in Decision Making: Invitation to Discuss

open access: yesEntropy, 2021
In this short paper, a critical analysis of the Neutrosophic, Pythagorean and some other novel fuzzy sets theories foundations is provided, taking into account that they actively used for the solution of the decision-making problems.
