An Approach for Constructing Hierarchy of Granules Based on Fuzzy Concept Lattices

Abstract

The key to granular computing (GrC) is to make use of granules in problem solving. With view of granular computing, this paper presents an approach for constructing hierarchy of granules based on fuzzy concept lattices. The knowledge granularity is discussed, and an algorithm for constructing hierarchical structure of coarser granules is also illustrated.
