Formal theory of granular computing, and two major applications

Abstract

The term granular computing (GrC), roughly speaking, is jointly coined by Lin and Zadeh in the fall of 1996 (Zadeh, 1998). Since then, special interest group conferences, workshops, special sessions and special issues have gradually flourished. Many opinions have been expressed. We shall mentioned our initial idea: Zadeh gave an intuitive definition in (Zadeh, 1996) and outline his seminal paper (Zadeh, 1997), where he said “TFIG (which is GrC) • • • • are mathematics in nature.” While we share his view, but took an incremental approach. The First GrC Model (neighborhood systems or pre-topology) was investigated (Lin, 1989, 1998) from the view of topological spaces, rough sets, databases and computer security.
