Abstract

This paper presents two SVM-like classification algorithms whose design criterion is to minimise the PAC-Bayes bound instead of to maximise the classification margin. A main goal of this work is to provide a good estimation of the generalisation capabilities of the algorithms, rather than just come up with new means to obtain a good (but unknown) classification rate in the test set. Some experiments illustrate the performance of these algorithms in comparison with the original SVM in a model selection plus classification task.
