【摘要】 基于属性约简的分明矩阵方法的思想,本文提出Rough集不可分明关系和不可分明集概念,给出了基于二进制的条件属性约简和属性值约简方法,该方法在形式上更加简单,二进制参加运算,运算速度快,并通过示例说明了该方法比传统的Rough集理论中的方法更优越。更多还原

【Abstract】 The article proposes a Rough set concept of impartibility pattern of the properties and their relationships set,which based on the theory of properties reduction by using discernibility matrixs.The article also presents a method of condition property and values of the property reduction.It is proved to be simiplier and quicker than the traditional method.Through the demonstration,the method is more superior than the traditional Rough set theory method.更多还原
