英文摘要 | For classification problems based on microarray data, the data typically contains a large number of irrelevant and redundant features. In this paper, a new gene selection method is proposed to choose the best subset of features for microarray data with the irrelevant and redundant features removed. We formulate these lection problemas a L1-regularized optimization problem, based on a newly defined linear discriminant analysis criterion. In stead of calculating the mean of the samples, a kernel-based approach is used to estimate the class centroid to define both the between-class separability and the within-class compactness for the criterion. Theoretic alanalys is indicates that the global optimal solution of the L1-regularized criterion can be reached with a general condition, on which an efficient algorithmis derived to the features election problem in a linear time complexity with respect to the number of features and the number of samples. The experimental results on ten publicly available microarrayda-tasets demon strate that the proposed method performs effectively and competitively compared with state-of-the-art methods. |
