Introduction: What You Always Wanted to Know about Rough Sets

  • Ewa Orłowska
Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 13)


In this chapter the major principles and the methodology of the rough set—style analysis of data are presented and discussed. A survey of various formalisms that provide the tools of this analysis is given. We discuss the aspects of incompleteness of information that can be handled in the presented formalisms. The formalisms are related to the methods and/or structures presented in this volume, in each case we point out a relevant link and we give the reference to the respective chapter.
