Approximation of Fuzzy Sets by Interval Type-2 Trapezoidal Fuzzy Sets

IEEE Transactions on Cybernetics, 2020
In this paper, we propose a gradient-based method to approximate a fuzzy set through a trapezoidal fuzzy set (TFS). By adding some constraints in the formulated optimization problem, the major characteristics of the fuzzy set such as the core, the major part of the support, and the shape of the membership function could be preserved; also the form of ...

Interval type-2 fuzzy sets in psychological interventions

Proceedings of 2013 IEEE International Conference on Vehicular Electronics and Safety, 2013
This paper presents a psychological intervention model through the mental health status and psychological intervention which are based on interval type-2 fuzzy sets. The studies are taken teachers' psychological health as example to analyze teachers' psychological health status as well as the linguistic dynamic orbits of teachers' psychological health ...

Short Remark on Fuzzy Sets, Interval Type-2 Fuzzy Sets, General Type-2 Fuzzy Sets and Intuitionistic Fuzzy Sets

2015
In this paper, we introduce specific types of intuitionistic fuzzy sets, inspired by the multi-dimensional intuitionistic fuzzy sets and the General Type-2 fuzzy sets. The newly proposed sets extend the opportunities of the General Type-2 fuzzy sets when modelling of particular types of uncertainty.

Interval Type-2 Fuzzy Rough Sets and Interval Type-2 Fuzzy Closure Spaces

2015
The purpose of the present work is to establish a one-to-one cor- respondence between the family of interval type-2 fuzzy reexive/toleranc e approximation spaces and the family of interval type-2 fuzzy closure spaces.
