Probabilistic rough sets: Approximations, decision-makings, and applications
The main objective of this special issue is to present readers with the significantly extended and improved versions of the articles presented at the International Conference on Rough Sets, Fuzzy Sets, and Granular Computing (RSFDGrC’05) held in Regina, Canada in September 2005. In the standard rough set model, the lower and upper approximations are defined based on the two extreme cases (full ...
متن کاملProbabilistic rough set approximations
Probabilistic approaches have been applied to the theory of rough set in several forms, including decision-theoretic analysis, variable precision analysis, and information-theoretic analysis. Based on rough membership functions and rough inclusion functions, we revisit probabilistic rough set approximation operators and present a critical review of existing studies. Intuitively, they are define...
متن کاملRough Approximations on Preordered Sets
In this paper, we investigate the properties of rough approximations defined by preordered sets. We study the relations among the lower and upper rough approximations, closure and interior systems, and closure and interior operators.
متن کاملCommunicative Approximations as Rough Sets
Introduction: Communicative approximations are equivalence relations. For considering Communicative approximation, new constructs are necessary including “rough points” and “rough intervals”. “Communication about quantities is defined on a shared conventional space, which constitutes a tessellation on the real number line”. The uncertainty which results from measurement error (±η) is defined on...
