The data dimension reduction is the main method that can enhance the data mining efficiency based on higher-dimension data set.In this paper
the method and the application using data transformation to reduce data dimension are studied.A general data transformation model is proposed.How to compute the data transformation matrix of the model with the principal component analysis method is introduced explicitly.And a application example about this method is given too.The example indicates that (it’s) possible to capture the maximum variations of the original variables with fewer variables.
