Abstract: Cross validation is the most commonly used technique in machine learning for tuning the learning algorithm in order to achieve better generalization error rate. In this talk we present a magic CV theory which can allow users to very efficiently tune the support vector machine and related algorithms. The theory also provides a straightforward way to prove the Bayes consistency of these algorithms. We demonstrate our method on extensive simulations and benchmark data studies.
