   <abstract xml:lang="ru">
    <p>В статье рассматривается задача прогнозирования оттока пользователей компьютерной игры на основе методов машинного обучения. Проведён анализ поведения игроков с учётом их уровня опыта, что позволило выделить однородные кластеры аудитории и адаптировать подходы к построению моделей для каждой группы. Для решения задачи использовались современные алгоритмы ансамблевого обучения, включая XGBoost, LightGBM и CatBoost, а также методы балансировки классов и отбора информативных признаков. Особое внимание уделено интерпретации результатов: применён комплекс объяснимых моделей, что позволило выявить ключевые факторы риска и повысить прозрачность принимаемых решений. Разработанные модели прошли апробацию на реальных данных и были интегрированы в бизнес-процессы компании, обеспечив своевременное выявление до 80% склонных к уходу пользователей и способствуя оптимизации стратегий удержания.</p>

    <p>This article addresses the challenge of predicting user churn in computer games using machine learning methods. The analysis of player behavior, taking into account the level of user experience, allowed for the identification of homogeneous audience clusters and the adaptation of modeling approaches for each group. State-of-the-art ensemble learning algorithms, including XGBoost, LightGBM, and CatBoost, were employed alongside class balancing techniques and feature selection methods. Special emphasis was placed on the interpretability of the results: a suite of explainable models was applied, making it possible to identify key risk factors and enhance the transparency of decision-making. The developed models were tested on real data and integrated into the company’s business processes, enabling the timely detection of up to 80% of users prone to churn and contributing to the optimization of retention strategies.</p>
