Examples
- The theory of rough sets , presented in 1982 by polish mathematician - z
数据挖掘是知识发现过程中的核心步骤。粗糙集理论是波兰数学家z - Rough set theory was proposed by polish mathematician pawlak , which used to represent the uncertain knowledge . rough set theory has become a main method for kdd due to its unique advantage in knowledge discovery
粗糙集合是波兰数学家pawlak提出的一种对不确定性知识的表示方法，粗糙集合理论凭借其独特的优势而在kdd领域中具有越来越重要的地位。 - The rough set theory ( rst ) , which was introduced by z . pawlak in 1982 , is a tool to deal with vagueness and uncertainty . its main idea is inducing decision or classification rule through knowledge reduction by keeping the classify ability
粗糙集理论是波兰数学家z . pawlak于1982年提出的一种处理不确定和不精确数据的理论，其主要思想是在保持分类能力不变的前提下，通过知识约简，导出问题的决策或分类规则。 - In the process of researching the foundation topic of jiangxi natural science - " the research and realization of data mining system model " , this thesis focus on the foundation topic ' s sub - subject that how to mine association rules in database
本论文是在研究《数据挖掘的系统模型研究与实现》这一江西省自然科学基金项目的过程中，着重研究如何在数据库中挖掘关联规则这一子论题，并在广泛深入学习众多专家学者(特别是波兰数学家z - Rs theory was proposed by pawlak in 1982 . the focus of rs theory is on the ambiguity caused by limited discernibility of objects in domain of discourse . fuzzy set theory was proposed by zadeh in 1965 and hinges on the notion of a membership function on the domain of discourse , assigning to each object a grade of belongingness in order to represent an imprecise concept . the combination of fuzzy sets and rough sets are a new study and is very value in fact
粗糙集理论是波兰数学家z . pawlak于1982年提出来的两种处理不确定和不精确数据的理论,是通过等价关系来研究对象之间的不可分辨关系;模糊集理论是美国控制论专家zadeh于1965年提出的一种处理非精确的现象的数学工具,是利用集合的特征函数来处理边界的不可定义性,在模糊集合中并没有应用对象之间不可分辨性的概念。
