(2005) Technical Report. Unpublished, Southampton, UK.


This paper presents a bound on the performance of a Support Vector Machine obtained within the PAC-Bayes framework. The bound is computed by means of the estimation of a prior of the distribution of SVM classi ers given a particular dataset, and the use of this prior in the PAC-Bayes generalisation bound. The quality of the bound is tested in a model selection task, where it is compared against other procedures to select models based on other PAC-Bayes bounds and ten fold cross-validation.
