Abstract: We consider the problem of classification of individuals sampled from a mixture of several components with different probability distributions. To construct a classifier we use kernel estimators of the density of components in the mixture for a one-dimensional random variable that is the projection of the vector of observations to a nonrandom direction . We obtain an estimator for the best possible direction . It is proved that the probability of error for the classifier based on converges to the minimal probability of error among all possible classifiers.
