Rough sets pawlak
WebRough set, which deals with vagueness and uncertainty, is a formal approximation of conventional set in a given approximation space, with lower and upper approximation (Pawlak 1982). Mathematically, basis of rough set theory is similarity or indiscernibility (Reddy and Reddy 2013). WebFor the classical conflict information ({+1, 0, - 1}), Pawlak and Zhi et al. given effective method to reveal the conflict reason from the aspect of rough set theory and three-way concept lattice, but these models lack the approach of finding the optimal feasible strategy.

WebOct 11, 2015 · The fundamental concept of crisp set has been extended in many directions in recent past. The notion of rough set by Pawlak being noteworthy among them. A rough set captures indiscernibility of elements in a set. In the view of granular computing, rough set model is researched by single granulation. WebRough set theory proposed by Pawlak in [17] is a relatively new soft computing tool for the analysis of a vague description of an ob-ject, and has become a popular mathematical framework for pat-tern recognition, image processing, feature selection, neuro computing, conflict analysis, decision support, data mining and knowledge discovery from ...

Pawlak, is a formal approximation of a crisp set (i.e., conventional set) in terms of a pair of sets which give the lower and the upper approximation of the original set.
