Research on ECOC SVMs

The generalization performance of ECOC SVMs was analyzed, as a result, the performance of ECOC SVMs is mainly determined by the SVM classifiers corresponding to its codewords, litttlely by its mathematical characteristics. The performance of each SVM is ordered by their separating margins and cross-validation error ratios. Three types of ECOC SVMs, whose performance are better, worse and common, are constructed by selecting different set of SVMs, the ECOC SVMs with a better performance might be constructed by the set of SVMs whose performances are better too, otherwise, its performance might be worse, which supports our viewpoint effectively and points out the direction for improving ECOC SVMs.
