Одной из таких характеристик является значение энергии взаимодействия атомов внутри структуры. Значение энергии важно для получения и других величин, таких как объемный модуль упругости структуры, модуль сдвига и др. В работе рассматриваются способ получения энергии взаимодействия двух атомов, основанный на методах машинного обучения. Модель, построенная на основе машиннообучаемого потенциала GAP (Gaussian Approximation Potential), обучается на заранее подготовленной выборке и позволяет предсказать значения энергии пар атомов для тестовых данных. В качестве признаков использовались значения координат взаимодействующих атомов, расстояние между атомами, значение постоянной решетки структуры, указание на тип взаимодействующих атомов, а также значение, описывающее окружение атомов.  Вычислительный эксперимент проводился с участием однокомпонентных соединений, таких как Si, Ge и С. Оценивались скорость получения энергии взаимодействующих атомов, а также точность полученного значения. Характеристики скорости и точности сравнивались со значениями, полученными с помощью многочастичного потенциала межатомного взаимодействия — потенциала Терсоффа. </p></abstract><trans-abstract xml:lang="en"><p>In the process of modeling multilayer semiconductor nanostructures, it is important to quickly obtain accurate values the characteristics of the structure under consideration. One of these characteristics is the value of the interaction energy of atoms within the structure. The energy value is also important for obtaining other quantities, such as bulk modulus of the structure, shear modulus etc. The paper considers a machine learning based method for obtaining the interaction energy of two atoms. A model built on the basis of the Gaussian Approximation Potential (GAP) is trained on a previously prepared sample and allows predicting the energy values of atom pairs for test data. The values of the coordinates of the interacting atoms, the distance between the atoms, the value of the lattice constant of the structure, an indication of the type of interacting atoms, and also the value describing the environment of the atoms were used as features. The coordinates of the atoms, the distance between the atoms, the lattice constant of the structure, an indication of the type of interacting atoms, the value describing the environment of the atoms were used as features. The computational experiment was carried out with structures of Si, Ge and C. There were estimated the rate of obtaining the energy of interacting atoms and the accuracy of the obtained value. The characteristics of speed and accuracy were compared with the characteristics that were achieved using the many-particle interatomic potential — the Tersoff potential.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кристаллические структуры</kwd><kwd>потенциальная энергия структуры</kwd><kwd>потенциал Терсоффа</kwd><kwd>машиннообучаемый потенциал</kwd><kwd>Gaussian Approximation Potentials</kwd><kwd>Gaussian Process Regression</kwd><kwd>машинное обучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>crystal structures</kwd><kwd>potential energy of structure</kwd><kwd>Tersoff potential</kwd><kwd>machine learning potential</kwd><kwd>Gaussian Approximation Potential</kwd><kwd>Gaussian Process Regression</kwd><kwd>machine learning</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке РФФИ проект № 19-29-03051 мк.
