| 摘 要： | 将完备信息系统中决策规则的不确定性度量引入到不完备信息系统中,充分讨论了条件属性值缺失时规则的不确定性度量表现为概率区间的特性,在此基础上给出了确信度和覆盖度的近似概率值,并利用确信度计算出规则对分类的反映程度.

| Abstract: | The uncertainty measurement method of decision rules in complete information system was firstly introduced into the incomplete information system.When some of attribute values are missing,the uncertainty measurement of decision rule shows the characteristics of probability interval.On the basis of that,the certain factor coverage factor can be measured by approximate probability value.Besides this,the reflection degree of rule to the knowledge classification can be computed using the certain factor. |
