分辨

The rough set required that discretization should be maintained indiscernibility of the original decision-making system, however, many algorithms before permitted approximate quality descended controlled certain scope.

Using this method, when new rule being added, we need not use all un-reduced rules to simplify decision algorithm, only the rules which are rule complete with respect to an indiscernibility class are simplified; using this reduced decision algorithm in the Knowledge Represent System in which the decision algorithm is not complete, the decision with unknown correctness will not arise.

Based on substitution of the indiscernibility relation by a dominance relation and a confident threshold value a set, an extension of the rough sets model is proposed, which can deal with possible inconsistencies in preferential multiple attribute decision tables and obtain preferential probabilistic decision rules made up of preference actions.

摘要通过用优势关系代替不可分辨关系，并设定置信阈值α，提出了一种可以从偏好多属性决策表中发现偏好概率规则集的扩展粗糙集模型。

Firstly,proposed an extended rough sets model based on concordance relation which relaxed the indiscernibility relation and tolerance relation.Secondly,redefined some concepts,such as the indiscernibility degree between two objects,the indiscernibility degree between two clusters,integrated approximation rate of the clustering result.

首先在经典粗糙集理论的基础上，通过松弛对象之间的不可分辨和相容性条件，得到了基于和谐关系的扩展粗糙集模型；然后定义了新的个体间不可区分度、类间不可区分度、聚类结果的综合近似精度等概念，提出了新的混合数据类型层次聚类算法。
