Abstract

A procedure for the automatic classification of eclipsing binaries is presented. The procedure is based on the data from 1029 classified systems and allows for the classification of a given system based on a set of observational parameters, even if the set is incomplete. The procedure is applied to six large surveys of eclipsing variables. About 5300 systems were classified for the first time and can be used for the determination of the astrophysical parameters of their components.
