J. Weston, R. Collobert, F. Sinz , L. Bottou and V. Vapnik. Inference with the Universum. Proceedings of the Twenty-third International Conference on Machine Learning (ICML 2006), IMLS/ICML, 2006.
In this paper we study a new framework introduced by Vapnik (1998; 2006) that is an alternative capacity concept to the large margin approach. In the particular case of binary classification, we are given a set of labeled examples, and a collection of rage the Universum by maximizing the number of observed contradictions, and show experimentally that this approach delivers accuracy improvements over using labeled data alone.
