摘要	Our study tried to deal with a gene expression problem from the view of factor analysis. In order to overcome the instability problem caused by using traditional Independent component analysis (ICA), an ensemble classifier of DNA microarray data based on a selective ICA method was proposed. At first, we analyzed the reconstruction error of each gene and selected a subset of independent components, which contributed relatively small reconstruction errors, to reconstruct new samples. After that, several Support vector machine (SVM) sub-classifiers were trained simultaneously. Finally, the best SVM sub-classifiers with high correct rates were selected to participate in the ensemble, using a majority voting method. Results on three publicly available DNA microarray datasets show the feasibility and validity of our proposed method.
