基于粗糙集理论在数据挖掘中的分析与应用-analysis and application of rough set theory in data mining

Applies based on the rough set theory in data minings researchAbstractWith the growing database，It has become increasingly urgent needs of people to obtain useful knowledge from the database automatically. Rough set theory (Rough Sets) is a new mathematical theory that is in the context of the continuous development of such a kind used for imprecise and uncertain data mining and processing . Rough set theory has an increasingly important position, with its unique advantages in the field of KDD. Polish mathematician Z. Pawlak in 1982, made of rough set theory is a new deal with ambiguity and uncertainty of knowledge of mathematical tools. Analysis and can effectively deal with inaccurate, inconsistent, incomplete information, etc., and to find hidden knowledge to reveal potential patterns. Rough sets in machine learning, knowledge acquisition, decision analysis, process control and many other fields have been widely used.Data Minim is of the process that mining interesting knowledge which stored in the database, data warehouse, or other information stored in a large amount of data. Many data mining techniques only applied to collect accurately,it does not apply to rough sets, It is a common phenomenon of rough sets in reality, the most prominent feature is to provide the data that is needed to deal with the collection of any a priori information is available directly from the the issue of a given point, to realize the thinking of Let the data guide the actions. so based on rough set data, mining model in the field of information system has important meaning.In this article, data mining and rough set theory of knowledge, especially knowledge of attribute reduction. It Gives in 2008 part of Chinas athletes the Beijing Olympic Games Awards knowledge with rough sets example; rough set based on the data mining model; colleges with students in Hunan employment information systems, as an example of the university students , It is very importance of using rough set theory sh
