По результатам определения изотопных отношений δ13C в аминокислотах после газохроматографического разделения выполнена процедура классификации образцов методами опорных векторов и линейного дискриминантного анализа. Точность прогнозирования составила 65-75%. Несмотря на невысокую правильность идентификации при использовании только покомпонентного анализа, существует возможность существенно повысить надежность классификации в комбинации с другими данными за счет расширения размерности по числу переменных.</p></abstract><kwd-group xml:lang="ru"><kwd>масс-спектрометрия</kwd><kwd>идентификация</kwd><kwd>изотопные отношения</kwd><kwd>GC-C-IRMS</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Amrani A., Sessions A.
