By combining ideas from three-way decision and Pedrycz shadowed sets, this paper
investigates two possible solutions to the problem of constructing a shadowed set from an …

This study is concerned with the design of a three-way classification mechanism realized
through combing fuzzy decision trees and expressing uncertainty associated with …

A Pawlak approximation space is a pair of a ground set/space and a quotient set/space of
the ground set induced by an equivalence relation on the ground set. The quotient space is …

Shadowed sets, proposed by Pedrycz, are an example of three-way approximations of fuzzy
sets. A fuzzy set is approximated by elevating membership grades at or above one threshold …

Three-way approximations can be constructed by shadowed sets based on a pair of
thresholds. The determination and interpretation of the thresholds is one of the key issues for …

In this study, a new technique of rough-fuzzy clustering based on multigranulation
approximation regions is developed to tackle the uncertainty associated with the fuzzifier …

The study is concerned with a granular data description in which we propose a
characterization of numeric data by a collection of information granules so that the key …

The fuzzy rating method has been introduced in psychometric studies as a tool, which allows
the capture of and accurate reflection of the diversity, subjectivity, and imprecision inherent …

Neighborhoods form a set-level approximation of data distribution for learning tasks. Due to
the advantages of data generalization and nonparametric property, neighborhood models …

A model of decision-theoretic three-way approximations of fuzzy sets that can calculate a
pair of interpretable thresholds (α, β) by combining shadowed sets with three-way decisions …
