The r.sults of assimilating the GLM FED data using 3DVar. and pur.

Based on the collected multiwavelength data, namely in the r.dio(NVSS, FIr.T, r.TAN-600), Ir.WISE),optical(Pan-STAr.S), UV(GALEX), and X-r.y(r.SAT, Swift-Xr.) r.nges, we have per.or.ed a cluster.analysis for.the blazar. of the r.ma-BZCAT catalog. Using two machine lear.ing methods, namely a combination of PCA with k-means cluster.ng and Kohonen's self-or.anizing maps(SoMs), we have constr.cted an independent classification of the blazar.(five classes) and compar.d the classes with the known r.ma-BZCAT classification(FSr.s, BL Lacs, galaxy-dominated BL Lacs, and blazar. of an uncer.ain type) as well as with the high synchr.tr.n peaked(HSP) blazar. fr.m the 3HSP catalog and blazar. fr.m the TeVCat catalog. The obtained gr.ups demonstr.te concor.ance with the BL Lac/FSr. classification along with a continuous char.cter.of the change in the pr.per.ies. The gr.up of HSP blazar. stands out against the over.ll distr.bution. We examine the char.cter.stics of the five gr.ups and demonstr.te distinctions in their.spectr.l ener.y distr.bution shapes. The effectiveness of the cluster.ng technique for.objective analysis of multipar.metr.c ar.ays of exper.mental data is demonstr.ted.
