For training an artificial neural network a database of anomalous magnetic field components B<sub>x</sub>, B<sub>y</sub>, B<sub>z </sub>was created using a set of point magnetic dipoles lying under the field measurement plane. Using a synthetic example, the work of a trained neural network was shown in comparison with a well-known numerical algorithm for restoring a vector field from data of one component. Further, according to the data of the vertical component of the anomalous geomagnetic field the horizontal components of the anomalous geomagnetic field were restored using artificial neural networks in the territory of 58 – 85° E, 52 – 74° N with a grid step of 2 arc minutes.</p></abstract><trans-abstract xml:lang="ru"><p>В данной работе с помощью искусственных нейронных сетей была решена задача о восстановлении векторного аномального магнитного поля по однокомпонентным данным. Для обучения искусственной нейронной сети была создана база данных компонент аномального магнитного поля B<sub>x</sub>, B<sub>y</sub>, B<sub>z </sub>с помощью набора точечных магнитных диполей, залегающих под плоскостью измерения поля. На синтетическом примере была показана работа обученной нейронной сети в сравнении с известным численным алгоритмом восстановления векторного поля по данным одной компоненты. Далее, по данным вертикальной компоненты аномального геомагнитного поля с помощью искусственных нейронных сетей были восстановлены горизонтальные компоненты аномального геомагнитного поля на территории 58–85° E, 52°–74° N с шагом сетки 2 угловых минуты.</p></trans-abstract><kwd-group xml:lang="en"><kwd>artificial neural networks</kwd><kwd>anomalous magnetic field</kwd><kwd>vector magnetic field</kwd><kwd>computer modeling</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>искусственные нейронные сети</kwd><kwd>аномальное магнитное поле</kwd><kwd>векторное магнитное поле</kwd><kwd>компьютерное моделирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Колесова В.И.
