多粒度粗糙集的结构
The structure of multigranular rough sets
摘要:
我们研究两个等价的多粒空间。给出了所谓“乐观”和“悲观”多粒近似系统的格论性质。我们还考虑了由这些近似对确定的粗糙集的有序集。
英文摘要:
We study multigranulation spaces of two equivalences. The lattice-theoretical properties of so-called "optimistic" and "pessimistic" multigranular approximation systems are given. We also consider the ordered sets of rough sets determined by these approximation pairs.
