Рассмотрены способы взаимодействия с отсутствующими значениями в наборе данных и способы их устранения в зависимости от различных факторов. Рассмотрены алгоритмы преобразования номинальных переменных в вид, пригодный для обучения моделей библиотеки Scikit-Learn. Также рассмотрен способ комбинирования алгоритмов преобразования данных для достижения наивысшей предиктивной способности по F1 мере на примере модели бинарной классификации.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, the feasibility of using various data preparation algorithms for better training of the model in the python3 programming language is considered. We describe how to interact with missing values in the data set and how to eliminate them, depending on various factors. Algorithms for converting nominal variables into a form suitable for teaching models of the Scikit-Learn library are considered. Also, a method of combining data conversion algorithms to achieve the highest predictive ability in F1 measure was applied using the example of a binary classification model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>подготовка данных</kwd><kwd>python3</kwd><kwd>one-hot-encoding</kwd><kwd>предиктивная способность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>data preparation</kwd><kwd>python3</kwd><kwd>one-hot-encoding</kwd><kwd>predictive ability</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">D.
