Abstract

Aiming at the problems that principal component analysis was unable to use the class information of the samples and the direction of the maximum principal component was likely to cause overlap of the samples from different classes, this paper proposed a feature transformation method fusing minimum principal component subspaces of different classes. Firstly, the proposed method analyzed the component of each class of data; and then it fused the projection results of the original data in all subspaces to form a new feature space; finally, this paper used the KEEL benchmark database to test the method. The results show that the proposed method can construct a feature space that is more conducive to classification compared with other feature transformation methods, which can help to improve the classification accuracy of the classifier.
