Основной целью работы является повышение эффективности работы нейросетевой модели при навигации мобильной робототехнической платформы в статических и динамически сгенерированных средах.</p></sec><sec><title>Методы</title><p>Методы. Для решения поставленной задачи были предложены точная настройка и оптимизация гиперпараметров нейронной сети. Для стимулирования агентов исследовать окружающую среду была проведена корректировка системы вознаграждений, предполагающая повышение вознаграждения при уменьшении расстояния от агента до целевой точки и увеличение штрафа при движении в направлении, противоположном конечной точке, и при прохождении каждой последующей сцены. Такое распределение вознаграждений и штрафов побуждает агентов активно обучаться и способствует сокращению общего количества сцен. С целью уменьшения объема данных, обрабатываемых нейронной сетью, была введена нормализация входных векторов. Было уменьшено время обучения модели нейронной сети благодаря параллельному обучению агентов и, как следствие, увеличения опыта в результате исследования окружающей среды.</p></sec><sec><title>Результаты</title><p>Результаты. Предложенный подход позволил сократить время обучения на 30% и повысить эффективность навигации мобильной платформы на 10% в динамически сгенерированной среде и на 22% в статической среде по сравнению с неоптимизированной моделью.</p></sec><sec><title>Заключение</title><p>Заключение. Предложенное решение может быть использовано совместно с другими методами трассировки и навигации, когда обученная нейронная сеть работает одновременно с уже отработанными и проверенными алгоритмами навигации. Например, если мобильная платформа подключает обученную нейронную сеть только для корректировки положения в пространстве и предотвращения столкновений с другими объектами</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of reseach</title><p>Purpose of reseach. The main purpose of this work is to increase the efficiency of a neural network model when navigating a mobile robotic platform in static and dynamically generated environments. </p></sec><sec><title>Methods</title><p> Methods. To solve this problem, precise setting and optimization of neural network hyperparameters were proposed. In order to encourage agents to explore the environment, the reward system was adjusted to increase the reward when the distance from the agent to the target point was reduced, and the penalty increased when moving in the opposite direction to the end point and passing each subsequent scene. This distribution of rewards and penalties encourages agents to learn actively and helps to reduce the total number of scenes. In order to reduce the amount of data processed by a neural network, normalization of input vectors was introduced. The learning time of the neural network model was reduced due to the parallel training of agents and, consequently, increased experience as a result of the environmental research. </p></sec><sec><title>Results</title><p>Results. The proposed approach reduced the learning time by 30% and improved the navigation efficiency of the mobile platform by 10% in a dynamically generated environment and by 22% in a static environment compared to the non-optimized model. </p></sec><sec><title>Conclusion</title><p>Conclusion. The proposed solution can be used in conjunction with other methods of tracing and navigation, when the taught neural network works simultaneously with the already developed and proven navigation algorithms, for example, if the mobile platform connects a taught neural network only to adjust the position in space and to prevent collisions with other objects. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мобильный робот</kwd><kwd>навигация</kwd><kwd>искусственные нейронные сети</kwd><kwd>обучение с подкреплением</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mobile robot</kwd><kwd>navigation</kwd><kwd>artificial neural networks</kwd><kwd>reinforcement learning</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">Artificial intelligence and collaborative robot to improve airport operations / F.
