| Abstract(in English) | This paper investigates the effects of confidence transformation in combining multiple classifiers using various combination rules. The combination methods are tested in handwritten digit recognition by combining varying classifier sets. The classifier outputs are transformed to confidence measures by combining three scaling functions and three confidence types. The combination rules include fixed rules (sum-rule, product-rule, max-rule, median-rule. etc.) and trained rules (linear discriminants and weighted combination with various parameter estimation techniques). From the experimental results, we can draw some conclusions as follows. (1) Confidence transformation is beneficial to the performance of classifier combination, either by fixed rules or by trained rules. (2) Trained combination rules mostly outperform fixed rules, particularly when the classifier set contain weak classifiers. (3) In combination using linear discriminant, the support vector machine with linear kernel (linear SVM) performs best. (4) The weighted combination with optimized weights performs as well as the linear SVM. |
