Перспективным направлением исследований является совмещение преимуществ каждого подхода в одном объединенном классификаторе. В статье предложен метод объединения этих подходов за счет встраивания локальных метрических признаков в подход, использующий глобальную оптимизацию. Данный подход продемонстрирован для случая, когда в качестве классификатора, использующего глобальную оптимизацию, применяются методы случайного леса (random forest) и особо случайных деревьев (extra random trees). Предложены различные варианты метрических признаков. Перспективность указанного подхода проиллюстрирована на примере решения задачи классификации типа лесных массивов, в которой добавление предложенных метрических признаков существенно улучшило точность классификации.</p></abstract><trans-abstract xml:lang="en"><p>Methods of classification by nature of decision-making divide on methods using global optimization (all training samples are used), and local optimization (only samples in the neighbourhood of the studied object are used). The perspective direction of research is combination of advantages of each approach in one integrated classifier. In article the method of combination of these approaches by embedding of local metric features into the approach using global optimization is proposed. This approach is shown for a case when the classifier using global optimization is random forest and extra random trees. Various variants of metric features are evaluated. Performance of the proposed approach is illustrated on the forest cover type prediction task, where it leads to significant improvement in classification accuracy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>классификация</kwd><kwd>решающие деревья</kwd><kwd>метрические признаки</kwd><kwd>тип лесного покрова</kwd></kwd-group><kwd-group xml:lang="en"><kwd>classification</kwd><kwd>decisive trees</kwd><kwd>metric signs</kwd><kwd>type of a forest cover</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">Chih-Fong Tsai, Chia-Ying Lin.
