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.

粗糙集理论的概念性框架之一就是利用不可分辨关系和布尔推理作为数据约简和获取决策规则的基础。

And the so-called violation of the principle of identicals of indiscernibility and transitivity of identity is because essential attributes and non-essential attributes are not differentiated.

而所谓不可分辨者同一原则和同一关系的传递性遭到破坏，乃是因为不区分本质属性和非本质属性。
