| 摘 要： | 粗糙集理论作为一种新的处理含糊和不确定性问题的数学工具,已成为国际学术界的一个前沿的研究领域.传统的粗糙集理论只能对数据库中的离散属性进行处理,而绝大多数现实的数据库既包含了离散属性,又包含了连续属性.针对传统粗糙集理论的这一缺陷,提出了一种改进的基于断点重要性的属性离散化方法.最后,通过实例分析说明该方法是有效的.

| Abstract: | Rough set theory is a relatively new soft computing tool to deal with vagueness and uncertainty, and is regarded as a field of leading edge. Rough set theory is deeply studied in this paper. An improved attribute discretization method is presented in this paper. At last, examples of recognizing the emitter purpose are selected to demonstrate this new method. Experimental results show that the performance of this new method is accurate and effective. |
