Intuitionistic Fuzzy Rough Approximation Operators
Sang Min Yun, Seok Jong Lee · International Journal of Fuzzy Logic and Intelligent Systems · 2015
Since upper and lower approximations could be induced from the rough set structures, rough sets are considered as approximations.The concept of fuzzy rough sets was proposed by replacing crisp binary relations with fuzzy relations by Dubois and Prade.In this paper, we introduce and investigate some properties of intuitionistic fuzzy rough approximation operators and intuitionistic fuzzy relations by means of topology.
