Real rough set theory and attribute reduction 实域粗糙集理论及属性约简
Abstract real field 抽象实域
Jacques hadamard " , , " the shortest path between two truths in the real domain passes through the complex domain . " , 实域中两个真理之间的最短路程是通过复域.
Vibration analysis software adopting win32 api , multi - thread design and modular configuration has such functions as real - time wave display , real and frequency domain analysis , data store and so on 振动分析软件采用统一的win32编程接口,多线程设计和模块化结构,可执行代码小,易于功能扩展;具有实时波形显示、实域频域分析、数据存盘等功能。
The modified method makes the output classification clearer and the intervals between different classes larger . furthermore , in order to handle the real attribute values conveniently , a real rough set theory based on the general neighborhood relation is proposed 在广义近邻关系下定义了实域粗糙集的基本概念,研究了相应的性质,并提出了一种基于beam搜索的实域粗糙集的属性约简方法。
