TL;DR
This paper explores the algebraic and topological structures of intuitionistic fuzzy values space, introduces new operators, and addresses open problems, with applications in pattern recognition.
Contribution
It establishes the algebraic and topological properties of IFV space, introduces a new strong negation operator, and constructs an isomorphism with q-ROFVs, extending existing theories.
Findings
The space of IFVs forms a complete lattice and a Kleene algebra.
The topological space of IFVs is compact and connected but not separable or metrizable.
An admissible similarity measure is constructed for pattern recognition.
Abstract
We prove that the space of intuitionistic fuzzy values (IFVs) with a linear order based on a score function and an accuracy function has the same algebraic structure as the one induced by a linear order based on a similarity function and an accuracy function. By introducing a new operator for IFVs via the linear order based on a score function and an accuracy function, we show that such an operator is a strong negation on IFVs. Moreover, we observe that the space of IFVs is a complete lattice and a Kleene algebra with the new operator. We also demonstrate that the topological space of IFVs with the order topology induced by the above two linear orders is not separable and metrizable but compact and connected. From some new perspectives,our results partially answer three open problems posed by Atanassov [Intuitionistic Fuzzy Sets: Theory and Applications, Springer, 1999] and [On…
