一种基于熵的不一致规则的处理算法

A Processing Algorithm of Incompatible Rules Based on Entropy

不一致规则对于我们发现异常信息有着十分重要的作用。在总结了许多对不一致规则处理算法的不足之后,我们提出了一种基于熵的不一致规则的修正算法。根据给定的可信度阀门值,使用这个算法我们可以判断出一个信息系统中不一致规则是否异常规则。最后结合一个实例阐明了该算法的基本思路。

Incompatible rules are very important for us to discover exceptional information . We sum up much shortcoming of many algorithms of processing incompatible rules and present a correcting algorithm of incompatible rules based on entropy. According to confidence which we assigned, we can judge whether rules of information system are exceptional rules. An example is given to demonstrate the main idea of this algorithm.
