Abstract.A stochastic model for the description of the classification problem is presented. Statistically motivated supervised and unsupervised training schemes for classifiers are considered; the resulting classifiers turn out to be asymptotically optimal. The rates of convergence of probability of successful classification to optimality are studied in a computer experiment. The supervised training scheme entails a sequence of classifiers whose quality converges faster to optimality than that in the unsupervised case.
