摘要
条件属性的重要性存在差异,通过引入差异度,对不完备信息系统中属性的重要性进行了定义,提出了一种基于权重联系度的属性约简算法。通过实例说明该算法能得到不完备决策表的最小相对约简。
Essentiality of attribute exists difference.The importance of attributes for incomplete information systems is defined based on the difference degree of attributes.It’s proposed an attribute reduction algorithm based on connection degree of attri-bute weights.Finally,an illustrative example analysis shows that this algorithm can find the minimal reduction for decision table.
