On rough sets induced by fuzzy relations approach in semigroups

open access: yesOpen Mathematics, 2018
In this paper, we introduce a rough set in a universal set based on cores of successor classes with respect to level in a closed unit interval under a fuzzy relation, and some interesting properties are investigated.

Distance and closeness measures in information spaces

open access: yes, 2006
Obiettivo della tesi è fornire strumenti teorici per il trattamento di informazione “incompleta”. Ciò viene fatto, da un lato, in un ambito metrico, definendo misure di “distanza” tra oggetti, dall’altro definendo nozioni suggerite dalla logica a più ...

Characterization of rough set approximations in Atanassov intuitionistic fuzzy set theory

open access: yes, 2011
The primitive notions in rough set theory are lower and upper approximation operators defined by a fixed binary relation and satisfying many interesting properties. Many types of generalized rough set models have been proposed in the literature.

Neutrosophic Soft Rough Graphs with Application

open access: yesAxioms, 2018
Neutrosophic sets (NSs) handle uncertain information while fuzzy sets (FSs) and intuitionistic fuzzy sets (IFs) fail to handle indeterminate information. Soft set theory, neutrosophic set theory, and rough set theory are different mathematical models for

Rough Set-Based Neuro-Fuzzy System

open access: yes, 2009
Neuro-fuzzy hybridization is the oldest and most popular methodology in soft computing (Mitra & Hayashi, 2000). Neuro-fuzzy hybridization is known as Fuzzy Neural Networks, or Neuro-Fuzzy Systems (NFS) in the literature (Lin & Lee, 1996; Mitra ...

Rough set-based neuro-fuzzy system.

open access: yes, 2008
Neuro-fuzzy systems is a popular hybridization in soft computing that abstracts a fuzzy model from given numerical examples using neural learning techniques to formulate accurate predictions on unseen samples.

Coverage-Based Variable Precision (I, PSO)-Fuzzy Rough Sets with Applications to Emergency Decision-Making

open access: yesInternational Journal of Computational Intelligence Systems
Considering the characteristics of imprecise, incomplete and fuzzy data in emergency environment, a novel emergency decision-making method based on coverage-based variable precision (I, PSO)-fuzzy rough set model is proposed.
