| 摘 要： | 提出一种基于粗糙集属性重要性的属性约简算法。该算法以所有条件属性为初始约简集合,以属性重要性为迭代准则,通过逐步缩减来求取约简。同时给出了该算法的时间复杂度分析,并举例验证了所提出算法的有效性和实用性。

| Abstract: | Proposed an algorithm of attribute reduction based on attribute importance of rough set.With all the condition attribute as the initial reduction,this algorithm takes importance of attribute as the iterative criterion to find reduction.The time complexity of the algorithm is analyzed and an example is investigated to verify it.The results show this algorithm can find the reduction effectively. |
