FRSA International Conference on Zdislaw Pawlak's 95th Birth Anniversary, November 2021. Abstract: Of the many generalizations of rough sets in the literature, graded rough sets are among the most controversial. When approached from a pointwise perspective, these are closely related to graded modal logic. In this research, a few granular generalizations are proposed by the present author. Some mistakes in the literature are rectified, and definable operations are examined by her. These are also relevant to the semantics of variable precision rough sets and generalizations thereof. |
