| Zusammenfassung: | When the missing values are obtained in incomplete fuzzy probabilistic rough sets over two universes, the time efficiency of the traditional static algorithm for updating approximations in incomplete fuzzy probabilistic rough sets over two universes is too low.To solve this problem, a label-based approach for dynamic updating approximations in incomplete fuzzy probabilistic rough sets over two universes isstudied.Firstly, some definitions of incomplete fuzzy probabilistic rough over two universes are given, then based on the matrix method, a label-based model of incomplete fuzzy probabilistic rough sets over two universes is proposed, and the related theorems are proved.After that, a label-based method for calculating approximations in incomplete fuzzy probabilistic rough sets over two universes is proposed and analyzed.Then, when the missing values are obtained in incomplete fuzzy probabilistic rough sets over two universes, the theorem for dynamic updating its approximations is proved, and a label-based alg |
