| 摘 要： | 文章基于粗糙集理论提出了一种新的增量式属性约简算法。当信息系统的对象和决策属性不变而不断增加条件属性时,通过该算法可动态地实现属性约简,由该算法得到的属性约简具有一定的实用价值。通过实例验证了该算法的正确性和有效性。

| Abstract: | In this paper,a new incremental algorithm for attribute reduction is provided based on rough set theory.The attribute reduction of new information system can be got by the algorithm in the dynamic mode when a condition attribute is added to the information system without the change of object and decision attribute.The algorithm is demonstrated to be effective with the specific example and the new attribute reduction is valuable in application. |
