Предложен новый метод генерации модельных наборов (Distributed Acoustic Sensing, DAS) сигналов различных классов. Статистические характеристики модельных сигналов аналогичны реальным DAS- сигналам соответствующих классов и могут быть использованы для повышения качества обработки DAS- сигналов методами машинного обучения. Метод. Представленный метод состоит в модификации технологии генеративных состязательных сетей (Generative Adversarial Network, GAN). Новизна подхода заключается во введении дополнительного контура внешнего контроля эффективности генеративной сети, который включает классификатор, обученный на доступном (малом) корпусе реальных DAS-сигналов. Основные результаты. Предложен оригинальный метод генерации модельных наборов DAS-сигналов, основанный на технологии GAN, и отличающийся от классической технологии наличием дополнительного контура внешнего контроля качества. Сформулирован критерий оптимальности генерирующей системы, который достигается путем пошагового реконфигурирования нейросетевой структуры GAN. Реконфигурирование основано на методе оптимизации Нелдера–Мида. Разработана и исследована на реальных данных программная реализация предложенного метода на платформе Python. Приведены результаты, доказывающие практическую эффективность рассмотренного подхода. Использование метода позволило увеличить мощность обучающего корпуса данных и, тем самым, повысить результирующую надежность классификации целевых DAS-сигналов. Обсуждение. Разработанный подход перспективен для применения в тех случаях, когда емкость представленных для обучения корпусов данных недостаточна для обеспечения высоконадежной классификации.</p></abstract><trans-abstract xml:lang="en"><p>A new method of generating model sets of Distributed Acoustic Sensing (DAS) signals of different classes is proposed. Statistical characteristics of model signals are quite similar to real DAS-signals of corresponding classes and can be used for sharp improvement of DAS-signals processing quality by machine learning methods. The proposed method is a modification of the Generative Adversarial Network (GAN) technique. The novelty of the approach lies in the introduction of an additional external control loop for the performance of the generative network which includes a classifier trained on an available (small) corpus of real DAS signals. A method for generating model sets of DAS signals based on GAN technology is proposed, and it differs from the classical technology by the presence of an additional external quality control loop. An optimality criterion for the generating system is formulated, the optimum of which is achieved by step-by-step reconfiguration of the GAN neural network structure. Reconfiguration is based on the Nelder-Mead optimization method. A software implementation of the proposed solution architecture on the Python platform is developed and tested on real data. Results are presented proving the practical efficiency of the proposed method. In particular, the proposed method allowed to increase the capacity of the training dataset and, thus, to increase the resulting reliability of the classification of target DAS signals. The developed approach is promising for use in cases where the capacity of the datasets provided for training is insufficient to ensure highly reliable classification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>GAN</kwd><kwd>машинное обучение</kwd><kwd>классификация</kwd><kwd>оптоволоконная система мониторинга</kwd><kwd>DAS</kwd><kwd>генеративная модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>GAN</kwd><kwd>machine learning</kwd><kwd>classification</kwd><kwd>fiber optic monitoring system</kwd><kwd>DAS</kwd><kwd>generative model</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">Timofeev A.V., Groznov D.I.
