Our aim of writing this manuscript is to found novel rough-approximation operators inspired
by an abstract structure called “supra-topology”. This approach is more relaxed than …

An improvement of rough sets' accuracy measure using containment neighborhoods with a medical application

TM Al-shami - Information Sciences, 2021‏ - Elsevier
The rough set theory is a nonstatistical mathematical approach to address the issues of
vagueness and uncertain knowledge. The rationale of this theory relies on associating a …

Soft sets and soft rough sets

F Feng, X Liu, V Leoreanu-Fotea, YB Jun - Information Sciences, 2011‏ - Elsevier
In this study, we establish an interesting connection between two mathematical approaches
