Based on the collected multiwavelength data, we perform a cluster analysis for the blazars of the Roma-BZCAT catalog, selecting groups of blazars with similar properties. Using machine learning methods, we constructed an independent classification of the blazars and compared it with the known Roma-BZCAT classification. The clustering algorithms divide both BL Lac-type objects and flat-spectrum radio quasars (FSRQs) into two subclasses along with a separate group of mixed BL Lacs and FSRQs. The clustering did not reveal difference between the BL Lacs and galaxy-dominated BL Lacs, unlike in the Roma-BZCAT classification.
