Данные для обучения и анализа получены с помощью Монте-Карло моделирования (алгоритм Метрополиса). Нейронная сеть обучалась на данных, соответствующих низкотемпературной фазе – ферромагнитной и высокотемпературной – парамагнитной, соответственно. После обучения нейронная сеть анализировала входные данные из всего температурного диапазона: от 0,1 до 5,0 (в безразмерных величинах J) и определяла точку Кюри Tc.</p></abstract><trans-abstract xml:lang="en"><p>The authors describe a method for determining the critical point of a second order phase transitions using a convolutional neural network based on the Ising model on a square lattice. Data for training and analysis were obtained using Monte Carlo simulations. The neural network was trained on the data corresponding to the low-temperature phase, that is a ferromagnetic one and high-temperature phase, that is a paramagnetic one, respectively. After training, the neural network analyzed input data from the entire temperature range: from 0.1 to 5.0 (in dimensionless units J) and determined the Curie point Tc.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модель Изинга</kwd><kwd>точка Кюри</kwd><kwd>метод Монте-Карло</kwd><kwd>свёрточная нейронная сеть</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ising model</kwd><kwd>Curie point</kwd><kwd>Monte Carlo method</kwd><kwd>Convolutional neural network</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Президента Российской Федерации для государственной поддержки ведущих научных школ РФ № НШ-2559.2022.1.2.</funding-statement><funding-statement xml:lang="en">This work was supported by a grant from the President of the Russian Federation for State Support of Leading Scientific Schools of the Russian Federation No. NSh-2559.2022.1.2.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cipra B.
