Then, an attribute reduction algorithm based on indiscernibility matrix is introduced.
给出了基于不可区分矩阵的属性频率约简算法。
Finding the core (s) and the reduction of information system is prime of rough sets by the method of indiscernibility relation from origin information system.
从原始信息系统出发,用不可分辨类的思想求解系统的核属性和约简是粗集理论的精华。
Rough sets theory provides a framework in which indiscernibility relations and Boolean reasoning form a foundation for data reduction and decision rule generation.
