Book ChapterDOI
A Comparative Study of Formal Concept Analysis and Rough Set Theory in Data Analysis
TL;DR: The theory of rough sets and formal concept analysis are compared in a common framework based on formal contexts to produce different types of rules summarizing knowledge embedded in data.
Book ChapterDOI
Three-Way Decision: An Interpretation of Rules in Rough Set Theory
TL;DR: A new interpretation of rules in rough set theory is introduced, which enables us to derive three types of decision rules, namely, positive rules for acceptance, boundary rules for indecision or delayed decision, and negative rules for rejection.
Granular Computing: basic issues and possible solutions
TL;DR: A set-theoretic model of GrC is proposed based on the notion of power algebras, with emphasis on the construction of granules and computation with granules.
Proceedings ArticleDOI
Concept lattices in rough set theory
TL;DR: Through the study of the introduced concept lattices, one can obtain an in-depth understanding of data analysis using rough set theory.
BookDOI
Data mining, rough sets and granular computing
TL;DR: This book discusses Granular Computing in Data Mining, Granular computing with Closeness and Negligibility Relations, and the application of Granularity Computing to Confirm Compliance with Non-Proliferation Treaty.
