Conceptual Reduction of Fuzzy Dual Concept Lattices

2010
In this paper we discuss the conceptual reduction of fuzzy dual concept lattices. Three pairs of operators in a fuzzy formal context are introduced. Based on the proposed operators, we present three types of variable threshold dual concept lattices. The properties and the relations of them are discussed.

Change mining in evolving fuzzy concept lattices

Evolving Systems, 2014
Fuzzy formal concept analysis enables us to add structure to data by ide ntifying coherent groups of related objects and attributes. In a situation where data is added dynamically, the concept lattice may evolve in different ways—either in content (more objects added to existing concepts) or in structure (entirely new concepts are created). This change

A Study of Bipolar Fuzzy Prime Ideals of a Lattice

Communications on Applied Nonlinear Analysis
This study explores the investigation of Bipolar Fuzzy Prime Ideals (BFPI) in lattices. We provide a detailed exploration of their properties, characterizations, and associated homomorphisms.

Construction of fuzzy concept lattice and its application

2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery, 2010
Aiming at the knowledge mining from fuzzy and uncertain information, the definition mode and properties of the fuzzy formal context are discussed in the paper. The method of constructing the fuzzy concept lattice of the fuzzy formal context is proposed, in that the definition of fuzzy product concept is the core: the intents of two concepts are ...

Fuzzy Concept Lattices Determined by (θ,σ)-Fuzzy Rough Approximation Operators

2009
Formal concept analysis and rough set analysis are two complementary approaches for analyzing data. This paper studies approaches to constructing fuzzy concept lattices based on generalized fuzzy rough approximation operators. For a Lukasiewicz implicator θ and its dual σ , a pair of (θ ,σ )-fuzzy rough approximation operators is defined.
