Эмпирическую основу составили несколько банковских датасетов, предоставленных автором; при этом в качестве центрального массива для построения модели выбран churn.csv, включающий 10 000 наблюдений и 14 признаков. В работе проведены структурный анализ данных, сопоставление вспомогательных массивов, разведочное изучение факторов, связанных с уходом клиентов, а также сравнительное тестирование моделей Logistic Regression, Random Forest и Gradient Boosting. Показано, что на вероятность оттока в наибольшей степени воздействуют возраст клиента, число используемых продуктов, уровень активности и географическая принадлежность. Наиболее высокие показатели качества продемонстрировал алгоритм Gradient Boosting. Результаты могут быть использованы при проектировании банковской CRM-системы, ориентированной на раннее выявление клиентов из риск-сегмента.</p> </abstract>           <kwd-group xml:lang="ru">  <kwd>прогнозирование</kwd>  <kwd>машинное обучение</kwd>  <kwd>банк</kwd>  <kwd>отток клиентов</kwd>  <kwd>клиентская аналитика</kwd>  </kwd-group>        </book-part-meta> </book-part> </front>  <back> <ref-list> <title>References</title>  <ref id="ref1"> <label>1</label> <citation-alternatives>   <mixed-citation xml:lang="en">Al-Najjar D., Al-Rousan N., Al-Najjar H.
