Kluwer Academic Publishers, … 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).
WebOct 12, 2005 · Fuzzy rough set is the generalization of Pawlak rough set to deal with both of fuzziness and vagueness in data. The existing research on fuzzy rough sets mainly concentrates on the construction of approximation operators. Less effort has been put on the attributes reduction of fuzzy rough sets. This paper mainly focuses on the attributes … WebXiaofei is the second author. Abstract: When approximating a concept, probabilistic rough set models use probabilistic positive, boundary and negative regions. Rules obtained from the three regions are recently interpreted as making three-way decisions, consisting of acceptance, deferment, and rejection.
