Prediction of the new coronavirus infection (COVID-19) spread is important to take timely measures and initiate systemic preventive and anti-epidemic actions both at the regional and state levels to reduce morbidity and mortality.</p></sec><sec><title>Objective</title><p>Objective: to develop a model for short-term forecasting of COVID-19 cases and deaths in the Russian Federation.</p></sec><sec><title>Material and methods</title><p>Material and methods. The data for the model training were collected from the Stopcoronavirus.rf and Johns Hopkins University portals. It included 13 features to assess the infection dynamics and mortality, as well as the rate of morbidity and mortality in different countries and certain regions of the Russian Federation. The model was trained by the CatBoost gradient boosting method and retrained daily with updated data.</p></sec><sec><title>Results</title><p>Results. The forecast model of COVID-19 cases and deaths for the period of up to 14 days was created. The mean absolute percentage error (MAPE) estimate of the model’s accuracy ranged from 2.3% to 24% for 85 regions of the Russian Federation. The advantage of the CatBoost machine learning method over linear regression was shown using the example of the root mean square error (RMSE) value. The model showed less error for regions with a large population than for less populated ones.</p></sec><sec><title>Conclusion</title><p>Conclusion. The model can be used not only to predict the pandemic of the novel coronavirus infection but also to control and assess the spread of diseases from the group of new infections at their emergence, peak incidence, and stabilization period.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Актуальность</title><p>Актуальность. Прогнозирование распространения новой коронавирусной инфекции (COVID-19) имеет важное значение для принятия своевременных системных профилактических и противоэпидемических мер как на региональном, так и на федеральном уровне с целью снижения заболеваемости и смертности.</p></sec><sec><title>Цель</title><p>Цель: разработать модель краткосрочного прогнозирования зараженных и умерших от COVID-19 в Российской Федерации.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Данные для обучения модели собраны c портала Стопкоронавирус.рф и ресурса Университета Джонcа Хопкинса. Она включает 13 признаков для оценки динамики заражения и летальности, а также скорости их прироста в разных странах и отдельных регионах Российской Федерации. Модель обучена методом градиентного бустинга CatBoost и ежедневно переобучается на обновленных данных.</p></sec><sec><title>Результаты</title><p>Результаты. Создана модель краткосрочного предсказания числа зараженных и умерших от COVID-19 на период до 14 дней. Оценка точности модели с учетом ошибки предсказания в процентах (англ. mean absolute percentage error, MAPE) составляет от 2,3% до 24% для 85 регионов России. Показано преимущество метода машинного обучения CatBoost перед линейной регрессией на примере величины среднеквадратичной ошибки (англ. root mean square error, RMSE). Модель показывает меньшую ошибку для регионов с большой численностью населения, чем для менее населенных областей.</p></sec><sec><title>Заключение</title><p>Заключение. Модель может быть использована не только для прогнозирования пандемии новой коронавирусной инфекции, но и для контроля и оценки распространения заболеваний из группы новых инфекций на этапах их возникновения, пика заболеваемости и периода стабилизации.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Искусственный интеллект</kwd><kwd>машинное обучение</kwd><kwd>градиентный бустинг</kwd><kwd>эпидемиологический прогноз</kwd><kwd>пандемия COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Artificial intelligence</kwd><kwd>machine learning</kwd><kwd>gradient boosting</kwd><kwd>epidemiological forecast</kwd><kwd>COVID-19 pandemic</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках Соглашения № 075-15-2021-665</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation under the Agreement No. 075-15-2021-665</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">WHO Coronavirus (COVID-19) Dashboard.
