摘要
利用逻辑推理和粒计算相互融合的研究成果,通过扩展近似空间,在形成的二维近似空间上定义了逻辑公式和公式确定的粒。为数据识别的需要,特别构造了一类重要的二维近似空间——矩形近似空间。经对矩形近似空间上公式确定的粒进行粒计算,得到矩形近似空间上公式粗糙描述的概念,由此可有效地实现对公式中隐含信息的识别,以达到数据保密传送的目的。这种基于粒计算的数据识别不仅表明前期理论研究的重要性,也表明理论结果的应用价值。
Based on the achievements in scientific researches on combining logical reasoning with granular computing,logical formulas and granules corresponding to the formulas are defined in a binary-dimensional approximate space obtained by expanding an approximate space.To make the needs of data recognition,an important binary-dimensional approximate space,rectangular approximate space,are specially constructed.Through granular computing on the granules corresponding to the formulas in the rectangular approximate space,a concept,rough description of a formula is proposed,so the information hidden in a formula can be recognized via using the formnla＇s rough description,and this method can effectively realize the purpose of maintaining secrecy when information is transferred.This data recognition by means of granular compnting not only indicates the importance, but also shows the practical value about of the theoretical researches in earlier stage.
