For particles identification an artificial neural network (ANN) was used, a multilayer perceptron being realized in JETNET and ROOT packages. It is demonstrated that, in order to get correct and comparable results, it is important to define the network structure correctly. The recommendations for such a selection are given. In order to achieve an acceptable level of pions suppression, the energy losses need to be transformed to more effective variables.</abstract><trans-abstract xml:lang="ru">Рассмотрена задача идентификации электронов и пионов по их потерям энергии в детекторе переходного излучения (TRD) эксперимента СВМ. Для идентификации частиц использовалась искусственная нейронная сеть - многослойный перцептрон, реализованный в пакетах JETNET и ROOT. В работе показано, что для получения корректных и сопоставимых результатов важно правильно выбрать структуру сети и приводятся соответствующие рекомендации. Для достижения приемлемого уровня подавления пионов требуется преобразование величин потерь энергии в слоях TRD к более «эффективным» переменным.</trans-abstract><kwd-group xml:lang="en"><kwd>multivariate analysis</kwd><kwd>pattern recognition</kwd><kwd>CBM experiment</kwd><kwd>transition radiation detector TRD</kwd><kwd>neural networks</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>многомерные методы анализа данных</kwd><kwd>методы распознаванияобразов</kwd><kwd>эксперимент СВМ</kwd><kwd>детектор переходного излучения TRD</kwd><kwd>искусственные нейронные сети</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Letter of Intent for the Compressed Baryonic Matter experiment. - http://www. gsi.de/documents/DOC-2004-Jan-116-2.pdf.</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>The CBM Collaboration.
