After probability theory, fuzzy set theory and evidence theory, rough set theory is a new
mathematical tool for dealing with vague, imprecise, inconsistent and uncertain knowledge …

This paper reviews and compares constructive and algebraic approaches in the study of
rough sets. In the constructive approach, one starts from a binary relation and defines a pair …

摘要在阐释粗糙集理论基本体系结构的基础上, 从多个角度探讨粗糙集模型的研究思路,
分析粗糙集理论与模糊集, 证据理论, 粒计算, 形式概念分析, 知识空间等其它理论之间的联系 …

A theory of three-way decision concerns the art, science, and practice of thinking, problem
solving, and information processing in threes. It explores the effective uses of triads of three …

Pythagorean fuzzy sets (PFSs) as a new generalization of intuitionistic fuzzy sets (IFSs) can
effectively handle uncertain information more flexibly in the process of decision making. As a …

Three-way decision is about thinking, problem-solving, and computing in threes or through
triads. Its philosophy and practice of triadic thinking appear everywhere. In particular, there …

Recently, the advancement of cognitive computing and three-way decisions has enabled in-
depth sequential pattern understanding through temporal association analysis. The main …

Three-way decisions provide a new research perspective for solving decision-making
problems. Under a multiple-criteria environment, this paper proposes a novel decision …

The rough set theory approximates a concept by three regions, namely, the positive,
boundary and negative regions. Rules constructed from the three regions are associated …

A theory of three-way decisions is constructed based on the notions of acceptance, rejection
and noncommitment. It is an extension of the commonly used binary-decision model with an …
