Abstract
This paper aims to introduce an effective method for improving rough set approximation accuracy.
Considering the j-neighborhood space, the lower and upper approximation operators are defined and their fundamental
properties are obtained. The approximations are constructed in four different approaches. Comparison between the
accuracy of these four types of approximations is imposed and the best one is defined
