通过对粗糙集中属性约简理论的研究,定义了等价类矩阵、等价类的线性表示、划分的线性相关、空划分等概念,给出了等价类矩阵构造算法并讨论了其性质,最后给出了基于线性相关思想的属性约简算法。
On the research of attribute reduction theory in rough sets, some new concepts are defined, such as equivalent class matrix, equivalent linear expressions, and divisive linear correlation, etc. This paper puts forward the algorithm of matrix, discussses its properties and finally puts forward algorithm of attribute reduction based on linear correlation.
