Abstract
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.
