摘要

中文摘要: 新对象添加到决策表后，已有的属性约简将会发生改变，需要对其动态更新。为此，首先给出简化决策表和简化差别矩阵的定义，并证明了基于简化差别矩阵的属性约简与正区域的属性约简是等价的；然后，分析增量对象的不同情况，将增量属性约简映射到简化决策表上来实现，由此设计基于简化差别矩阵的增量式属性约简算法，并对算法进行改进；最后，利用实例和实验验证了所提出算法的正确性和高效性。

Abstract

Abstract:In order to update the attribute reduction of decision table dynamically

the definitions of the simplified decision table and attribute reduction based on simplified discernibility matrix were proposed. It was proved that attribute reduction acquired from the definition is equivalence to attribute reduction based on positive region. Then the different cases of added object were analyzed

and incremental attribute reduction was mapped to the simplifying decision table to achieve. Finally

the attribute reduction algorithm based on simplified discernibility matrix was designed and the algorithm was further improved. The example and experiment results showed that the algorithms are effective and effieient.
