[0105] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and the drawings. Here, the exemplary embodiments of the present invention and the description thereof are used to explain the present invention, but not as a limitation to the present invention.
[0106] The inventors analyzed and studied the experimental source code of the L2 norm-SVM, L1 norm-SVM and L0 norm-SVM classification algorithms and found that the L2 norm, L1 norm and L0 norm regularized SVM classification algorithm training The obtained model weight vector w is not a sparse vector, that is, the magnitude of each component of the model weight vector w is basically the same. Feature selection requires artificially retaining the d components with the largest value in the model weight vector w, and zeroing the remaining components in the model weight vector w, and ...
