Title
A Fuzzy Measure Based on Variable Precision Rough Sets
Abstract
A variable precision rough set(VPRS) is an extension of a Pawlak rough set. By setting a threshold beta, VPRS loosens the strict definition of approximate boundary in Pawlak rough sets. This paper deals with uncertainty of rough sets based on the VPRS model. A measure is first defined to characterize fuzziness of a set in an information system. A pair of lower and upper approximations based on the fuzzy measure are then defined. Properties of the fuzzy measure and approximations are also examined.
