The Binary Discernibility Matrix''''s Transformation and High Efficiency Attributes Reduction Algorithm''''s Conformation
二进制可辨矩阵的变换及高效属性约简算法的构造

This paper dose a lot of mathematics transformation to Binary Disernibility Matrix,it is called BDM too.Though these transformations,we may both decrease a lot of memory space of BDM and contribute to make high efficiency attributes reduction algorithms.Based on BDM,we also give three algorithms which are in turn used to reduce BDM,attribute‘‘‘‘s reduction and judge reduction.Finally,ew give three examples to illuminate the feasibility of three algorithms and analyze the complexity of algorithms.
