文章在信息表的信息度量的基础上,主要做了如下两方面的工作:给出了一种基于Roughset理论提取决策规则的信息度量方法;提出了一种衡量提取决策规则优劣的目标函数,该工作为基于Roughset理论规则提取的进一步研究提供了一定的理论依据。论文的最后提出了有待解决的问题。
Based on the information measure of the information table, the paper mainly focuses on the following two aspects: An information measure method based on Roughset theory to extract decision rules is proposed. An objective function to measure the quality of the extracted decision rules is proposed. This work provides a theoretical basis for further research based on Roughset theory. At the end of the thesis, some problems to be solved are put forward.
