Abstract

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. The result shows that the number of concepts in variable threshold dual concept lattices is less than that in fuzzy dual concept lattices, and the important concepts are preserved.
