Granular computing emerges as a general way of computation and interpretation aimed at processing granular information. The underlying concept permeating the entire area is the one of information granules and information granulation. We discuss and contrast the most commonly encountered vehicles of information granulation such as set theory (especially interval analysis), fuzzy sets, rough sets, shadowed sets, random sets, etc. We discuss the underlying processing principles that are unique to the assumed formalism of information granulation. An important question dealing with a way of translation of information granules between processing frameworks exhibiting different leves of information granularity will be addressed as well. Owing to its inherent nature, granular computing promotes a notion of relational rather than function-driven mappings and this aspect contributes to the increased generality of the resulting constructs. Finally, we discuss granular neurocomputing and granular rule-based architectures in the setting of granular computing.
