Перспективным методом прогнозирования представляется алгоритм случайного леса деревьев решений (Random Forest) с использованием итеративного отбора наиболее значимых климато-океанологических предикторов. Определены три достоверно влияющих предиктора для модели случайного леса. Ошибка прогноза при этом составила 28%. Для верификации полученных результатов использованы альтернативные методы отбора наилучших признаков. Полученные результаты показали возможность использования исследуемых климато-океанологических предикторов для моделирования прогнозов динамики численности горбуши Западной Камчатки.</p></abstract><trans-abstract xml:lang="en"><p>An improvement of the forecast of pink salmon runs is one of the most actual problems in management of salmon stocks of Kamchatka. Algorhythm of Random Forest with the use of iterative selection of most important climate-oceanological predictors seem to be promising. Three authenticly influental predictors have been found for the model of Random Forest at the error of the forecast of 28%. Verification of the obtained results used alternative methods of selection of the best predictors. Obtained results have demonstrated possibility of the use of considered climate-oceanological predictors in modeling the forecasts of stock abundance dynamics of pink salmon in Western Kamchatka.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>горбуша Западной Камчатки</kwd><kwd>динамика численности подходов</kwd><kwd>прогнозирование</kwd><kwd>классификация</kwd><kwd>моделирование</kwd><kwd>случайный лес</kwd><kwd>дерево решений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pink salmon of Western Kamchatka</kwd><kwd>stock abundance dynamics of runs</kwd><kwd>forcasting</kwd><kwd>classification</kwd><kwd>modeling</kwd><kwd>random forest</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">Бугаев А.В., Тепнин О.Б. 2015.
