Foundations of Rough Sets from Vagueness Perspective
Handling vagueness was one of the motivations for proposing the rough set theory (Pawlak, 2004, see also Pawlak, 1982, 1991, 2003). In this chapter, we present algebraic foundations of the rough set theory from that perspective. Vagueness is understood according to the tertium.non.datur principle from traditional logic; the contemporary version of this principle is called the law of excluded mi...
متن کاملFoundations of Vagueness : a Category-theoretic Approach
The idea that vagueness has its origin in indiscernibility is not new. In this paper, we have tried to establish this thesis on a category-theoretic basis. In the process some other related notions, e.g. property, have been clari ed.
متن کاملFrom vagueness in medical thought to the foundations of fuzzy reasoning in medical diagnosis
OBJECTIVE This article delineates a relatively unknown path in the history of medical philosophy and medical diagnosis. It is concerned with the phenomenon of vagueness in the physician's "style of thinking" and with the use of fuzzy sets, systems, and relations with a view to create a model of such reasoning when physicians make a diagnosis. It represents specific features of medical ways of t...
متن کاملSpatial Vagueness and Second-Order Vagueness
This paper presents a geometric characterization of geographic objects with vague boundaries. Since the framework is based on ordering geometry and does not rely on numerical concepts, it can be applied to qualitative spatial reasoning. The characterization describes vague regions and gradual transitions between two vague regions. This approach takes into account that the region of all points t...
