An approach is proposed to construct classifiers based on kernel density estimates for solving pattern recognition problems. The approach is based on the use of the a posteriori probability and a distributive π-type measure for the effective division of competing sets. The family of density estimates is applied to each set in a wide range of bandwidths for each estimate of the class density. A procedure is proposed and adapted to combine the classification results on different levels of smoothing that provides a flexible use of different bandwidths for different pairs of competing classes. Statistical uncertainties are calculated on the basis of approximate estimated probabilities of a misclassification.
