基于数据仓库的数据预处理模型的算法研究

Study on the Model and Algorithms of Data Preprocessing Based on the Data Warehouse

数据仓库中的数据必须进行预处理后才能达到数据挖掘的要求。将数据预处理集成于数据仓库的构建过程中,提出一种基于数据仓库的数据预处理过程模型。讨论了数据预处理的各种算法并通过实例说明利用信息增益进行数据预处理的过程。

The data of the data warehouse cant meet the request of attaining the data mining until they carry on data preprocessing. This paper gathers data preprocessing in the process of the data warehouse, puts forward a kind of data＇s preparation to handle the process model, discusses kinds of algorithms and elucidate with facts the process in which the information is used to gain the benefit.
