Classic generalized rough set model in neighborhood systems provides a more general framework for depicting approximations, while it may meet the non-reflexive situations. Some scholars put forward different neighborhoods, such as adhesion neighborhoods (briefly, Pj
-neighborhoods), containment neighborhoods (briefly, Cj
-neighborhoods), and Ej
-neighborhoods. However, not all of them are reflexive. Moreover, the granularity of Pj
-neighborhoods and Cj
-neighborhoods are too fine, and that of Ej
-neighborhoods too coarse. To solve the problem, we aim to design a novel construction approach of neighborhoods, called variable j-containment neighborhoods (briefly, Vβj
-neighborhood... |
