| 摘 要： | 属性约简是粗糙集研究的重要内容之一，首先利用反例指出蔡莉等人提出的基于依赖度的决策表约简算法的错误，然后给出一种新的基于属性依赖的约简算法。通过一个信息系统实例，证明该算法的可行性和有效性。

| Abstract: | Attribute reduction is one of the major contents of rough set research.The paper first points out the mistake by Cai Li through counter-examples about her decision-making reduction algorithm based on dependence.Then the paper offers a new reduction algorithm.Finally,an information system example is used to prove its feasibility and effectiveness. |
