On the Properties of Covering Rough Sets Model
Zhongyin Xu, Qin Wang · Journal of Henan Normal University · 2005
This paper is devoted to the study of the covering rough set model. The topological structure of the corresponding rough sets is established and the equivalence between covering rough set model and reflexive, transitive relation based generalized rough set model is proved. Also, the axiomatic description of covering rough set model is given.
