Abstract

Granular Computing (GrC) operates with granules (generalized subsets) of data as pieces of basic knowledge. Rough Set Theory (RST) is a leading special case of GrC approach. In this paper, we outline a roadmap that stepwise refines RST into GrC. A prime illustration is that GrC of symmetric binary relations is a complete topological RST on granular spaces, where the adjective complete means that the representation theory can fully reflect the structure theory
