Cascade Support Vector Machines with Dimensionality Reduction

Figure 5

Illustration of ECM training characteristics: (a) development of the number of support vectors during a typical run; the number of support vectors is decreasing approximately linearly and (b) runtime comparison of SVM and ECM on an increasing training set size with and on MakeClass with and .
