the low approximation set 下近似集
In this paper, we discuss rough set approximation under granulation, and establish positive approximation under dynamic granulation.
本文讨论了粒度意义下的粗糙集近似,并定义了动态粒度下的正向近似。
The thesis studies the generalized rough set models and proposes a multi-level rough set approximation model CBM-RS based on a covering of the universe.
作者研究了粗糙集扩展理论,提出了一种多层粗糙集模型CBM-RS。 该模型是一种基于覆盖的扩展的多层粗糙集模型。
And, if we set these things equal, what we get is actually, we are replacing the function by its linear approximation.
如果把这两个看做等价的,实际上,就是用函数的线性近似式来代替原函数。
