Rough set theory, initiated by Pawlak, is a mathematical tool in dealing with inexact and incomplete information. Numerical characterizations of rough sets such as accuracy measure, roughness measure, etc, which aim to quantify the imprecision of a rough set caused by its boundary region, have been extensively studied in the existing literatures. However, very few of them are explored from the viewpoint of rough logic, which, however, helps to establish a kind of approximate reasoning mechanism… 


Rough Truth Degrees of Formulas and Approximate Reasoning in Rough Logic
A propositional logic PRL for rough sets was proposed in [1]. In this paper, we initially introduce the concepts of rough (upper, lower) truth degrees on the set of formulas in PRL. Then, by grading
A Geometry of Approximation: Rough Set Theory: Logic, Algebra and Topology of Conceptual Patterns
A Geometry of Approximation links many areas of academic pursuit without losing track of its focal point, Rough Sets, which will be useful to researchers, graduate and pre-graduate students from various disciplines, such as computer science, mathematics and philosophy.

The term fuzzy logic is used in this paper to describe an imprecise logical system, FL, in which the truth-values are fuzzy subsets of the unit interval with linguistic labels such as true, false,
Rough Sets Through Algebraic Logic
It is observed that rough algebra is more structured than a tqBa, and two more structures, viz. pre-rough algebra and rough algebra, are denned.
Mining Numerical Data - A Rough Set Approach
The conclusion is that even though MLEM2 was most frequently a winner, the differences between all four data mining methods are statistically insignificant.
