dc.description.abstract	© 2015, Pleiades Publishing, Inc. A new method for measuring the redshifts of galaxy clusters based on photometric SDSSIII data is presented. Highly accurate photo-z measurements for red-sequence galaxies using machine learning techniques on a training sample of luminous red BOSS LOWZ galaxies allow the redshifts of clusters at z < 0.45 to be determinedwith an accuracy σ<inf>norm</inf> = 0.011. The accuracy of the proposed method has been estimated on galaxy clusters from the 400d catalog.
