Abstract: Support Vector Classification has shown great performance in practice as a two class classification methodologyHowever,it is required that every input must be exactly assigned to one of these two classes without any uncertainty. In this paper,we propose USVC early-warning algorithm on expert advices,which is able to deal with the training data with uncertaintyThe application field of our algorithms is,wider than the SFVM method,although uncertainty is also considered thereMoreover,early warning of grain security is solved by USVC algorithm.
