© 2017 IOP Publishing Ltd and Sissa Medialab srl. The technique of discrimination of the e + e - e + e - and e + e - → π + π - events in energy range 0.5 < √s < 1 GeV by energy deposition in the calorimeter of SND detector was developed by applying machine learning method. Identification efficiency for e + e - → e + e - and e + e - → π + π - events in the range from 99.3 to 99.8% has been achived.
