摘要
In present paper, based on the classical fuzzy entropy,the fuzziness of variable precision rough sets ingeneralized approximation space are discussed by theaxiomatized method. And the same time, a generalframework that is studied the fuzziness of the rough sets ingeneralized approximation space is given. Meanwhile, theprobablity measure is introduced to the generalizedapproximation space and the generalized variableprecision probability rough sets model is established.Furthermore, several properties of the model are studied.Finally, the fuzziness of the generalized variable precisionrough sets is discussed by the method that is proposed inthis paper, too.
