| 摘 要： | 粗糙集理论是一种有效的信息处理工具,决策表属性约简是粗糙集理论研究的一个核心内容。利用RoughSet理论的相关知识,提出了一种基于包含度的决策表属性约简算法。与现有的决策表属性约简算法进行比较,它具有较低的复杂度和较强的可使用性。最后对UCI机器学习数据库中的例子进行约简的实验结果证明,它可以取得比较满意的效果。

| Abstract: | Rough Set is an efficient information processing tool and attribute reduction of decision table is a kernel part of research in Rough Set Theory.Using the knowledge of Rough Set Theory,an attribute reduction algorithm of decision table based on inclusion degree is put forward.Comparing with the old attribute reduction algorithms,it has lower complex degree and has powerful usability.Finally,it reducts examples of UCI databases and the results show that it can get better effects. |
