    <p>В статье приведено исследование возможности использования методов машинного обучения для классификации экзопланет на основе астрономических данных. Объектом исследования являются экзопланеты, а предметом - подходы к построению и интерпретации моделей классификации экзопланет по их физическим и орбитальным характеристикам. Набор данных Exoplanet Classification Dataset содержит 19761 наблюдение и 16 признаков, включающих параметры звезд, данные фотометрии, а также результирующую метку класса. Разделен набор данных на выборки: обучающая выборка (12646 объектов - 64 %), валидационная выборка (3162 объектов - 16 %), тестовая выборка (3953 объектов - 20 %). Распределено количество объектов по классам: класс 0 - 6311 объектов, класс 1 - 7413 объектов, класс 2 - 6015 объектов, класс 3 - 22 объекта. Выполнена предобработка данных, включающая нормализацию признаков, обработку пропусков и балансировку классов методом SMOTE (Synthetic Minority Over-sampling Technique). Для реализации модели машинного обучения выбран алгоритм Random Forest. Описано сравнение алгоритма Random Forest с другими алгоритмами классификации: логистической регрессией, методом опорных векторов (Support Vector Machine, SVM), градиентным бустингом и простой нейронной сетью (MLP). Проведен сравнительный анализ использования метода SMOTE. Проведена оценка адекватности разработанной модели с использованием метрик точности (Precision), полноты (Recall). Итоговая точность классификации экзопланет на тестовой выборке составила 75 %. На основе полученных моделей определена важность физических признаков, влияющих на принадлежность экзопланет к различным типам, что позволяет интерпретировать результаты не только с точки зрения машинного обучения, но и с позиции астрофизики. Разработанная модель машинного обучения является основой для интеллектуальных систем поддержки научных открытий в современных космических исследованиях.</p>

    <p>This article presents a study of the feasibility of using machine learning methods to classify exoplanets based on astronomical data. The object of the study is exoplanets, and the subject is approaches to constructing and interpreting exoplanet classification models based on their physical and orbital characteristics. The Exoplanet Classification Dataset contains 19,761 observations and 16 features, including stellar parameters, photometry data, and the resulting class label. The dataset is divided into samples: a training sample (12,646 objects - 64 %), a validation sample (3,162 objects - 16 %), and a test sample (3,953 objects - 20 %). The number of objects is distributed among classes: class 0 - 6,311 objects, class 1 - 7,413 objects, class 2 - 6,015 objects, and class 3 - 22 objects. Data preprocessing was performed, including feature normalization, gap handling, and class balancing using the Synthetic Minority Oversampling Technique (SMOTE). The Random Forest algorithm was selected to implement the machine learning model. A comparison of the Random Forest algorithm with other classification algorithms is described: logistic regression, support vector machine (SVM), gradient boosting, and a simple neural network (MLP). A comparative analysis of the SMOTE method is conducted. The adequacy of the developed model was assessed using the precision and recall metrics. The final accuracy of exoplanet classification on the test set was 75 %. Based on the resulting models, the importance of physical features influencing the classification of exoplanets into different types was determined, which allows the results to be interpreted not only from a machine learning perspective, but also from an astrophysical perspective. The developed machine learning model forms the basis for intelligent systems supporting scientific discoveries in modern space exploration.</p>
