Данная работа посвящена преодолению высоких требований к вычислительным ресурсам и объему оперативной памяти путем разработки методов эффективной оптимизации генеративно-состязательных сетей, адаптированных для генерации сигналов электрокардиограмм.Метод. В работе использованы методы глубокого обучения генеративно-состязательных сетей, способы обработки сигналов электрокардиограмм и реализации адаптивной квантизации весовых коэффициентов по поиску оптимального уровня квантизации для снижения потребления памяти при сохранении качества синтеза данных.Результат. В результате проведённых экспериментов была разработана и обучена собственная архитектура генеративно-состязательной сети для синтеза сигналов электрокардиограмм. Сравнительный анализ метрики Fréchet Distance подтвердил высокое сходство сгенерированных данных с реальными ЭКГ-записями. Разработанный метод адаптивного квантования AGWR обеспечил сокращение потребления оперативной памяти на 75% при сохранении качества синтеза, превосходя традиционный подход Min-Max даже при экстремальном сжатии весов до 4 бит.Вывод. Работа преодолевает ограничения GAN по вычислительным ресурсам, открывая возможности для практического внедрения в медицинские системы с ограниченными аппаратными ресурсами. Предложенная методика способствует восполнению дефицита клинических данных, ускоряя развитие интеллектуальных диагностических инструментов и персонализированной медицины в области сердечно-сосудистой патологии</p></abstract><trans-abstract xml:lang="en"><p>Objective. This work is devoted to overcoming high requirements for computational resources and RAM volume through the development of effective optimization methods for generative adversarial networks, adapted for generating electrocardiogram signals.Method. The work employed methods of deep learning generative adversarial networks, electrocardiogram signal processing techniques, and implementations of adaptive quantization of weight coefficients for searching the optimal quantization level to reduce memory consumption while maintaining data synthesis quality.Result. Based on experiments, a proprietary architecture of a generative adversarial network for synthesizing electrocardiogram signals was developed and trained. Comparative analysis of the Fréchet Distance metric confirmed high similarity between generated data and real ECG recordings. The developed adaptive quantization method AGWR achieved a 75% reduction in RAM consumption while maintaining synthesis quality, outperforming the traditional Min-Max approach even at extreme weight compression to 4 bits.Conclusion. The work overcomes the computational resource limitations of GANs, opening opportunities for practical implementation in medical systems with constrained hardware. The technique helps fill the gap in clinical data, accelerating the development of intelligent diagnostic tools and personalized medicine in cardiovascular pathology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>генеративно-состязательные сети</kwd><kwd>методы оптимизации</kwd><kwd>квантизация весовых коэффициентов электрокардиографических сигналов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>generative-adversarial networks</kwd><kwd>optimization methods</kwd><kwd>quantization of weighting coefficients of electrocardiographic signals</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">Hannun A.
