- Abstract:
-
In the existing intuitionistic fuzzy (IF) probabilistic rough set model of two universes, the probabilistic rough lower and upper approximations of a classical set under IF binary relation are discussed by setting two thresholds, ${\lambda _1}\;{\rm{and}}\;{\lambda _2}$. However, this model is unable to calculate the probabilistic rough lower and upper approximations of IF sets under IF binary relation, which limits the application of this model to a certain extent. In this study, we first define the IF conditional probability. Then, the generalized IF probability rough set models are constructed in IF probabilistic approximation space. In addition, the main properties of the model are discussed. Finally, the numerical examples of clinical diagnostic systems are applied to illustrate the validity of the proposed models. Compared with other models, the proposed generalized IF probabilistic rough set models further enrich the probabilistic rough set theory and are more suitable for practical applications.
