Research on Data Preprocessing in Supermarket Customers Data Mining

This paper focuses on the research of data preprocessing in data mining. Experiments are carried out on the transaction data of customs in some medium-sized supermarket. During the process of data analyzing and processing, correlation analysis method is used in order to identify which attributes could be integrated. In this process, data scale is reduced enormously and data with relatively small absolute value increases in the integration. Consequently, optimization of analysis result is reached and analysis difficulty has been reduced greatly.
