Основная их область применения это задачи распознавания и обработки изображений, речи, а также робототехника и беспилотные системы. Использование нейронных сетей связано с большими вычислительными затратами. Отчасти именно этот факт сдерживал их прогресс, и только с появлением высокопроизводительных вычислительных систем  началось активное развитие данной области. Тем не менее, вопрос ускорения работы нейросетевых алгоритмов все еще актуален. Одним из перспективных направлений является создание аналоговых реализаций искусственных нейронных сетей, так как аналоговые вычисления производятся на порядки быстрее, чем цифровые. В качестве базового элемента, на котором строятся такие системы, выступает мемристор. Мемристор представляет собой резистор, проводимость которого зависит от суммарного пройденного через него заряда. Объединение мемристоров в матрицу (кроссбар) позволяет реализовать на аппаратном уровне один слой искусственных синапсов. Традиционно в качестве аналогового метода обучения применяется метод STDP, основанный на правиле Хебба. В работе выполняется моделирование двухслойной полносвязной сети с одним слоем синапсов. Мемристивный эффект может проявляться в разных веществах (в основном в разных оксидах), поэтому важно понимать, как характеристики мемристоров будут влиять на параметры нейронной сети. Рассматриваются два оксида: оксид титана (TiO2) и оксид гафния (HfO2). Для каждого оксида выполняется параметрическая идентификация соответствующей математической модели для наилучшего согласования с экспериментальными данными. Производится настройка нейронной сети в зависимости от используемого оксида и моделируется процесс ее обучения распознаванию пяти шаблонов.</p></abstract><trans-abstract xml:lang="en"><p>Artificial neural networks play an important role in the modern world. Their main field of application is the tasks of recognition and processing of images, speech, as well as robotics and unmanned systems. The use of neural networks is associated with high computational costs. In part, it was this fact that held back their progress, and only with the advent of high-performance computing systems did the active development of this area begin. Nevertheless, the issue of speeding up the work of neural network algorithms is still relevant. One of the promising directions is the creation of analog implementations of artificial neural networks, since analog calculations are performed orders of magnitude faster than digital ones. The memristor acts as the basic element on which such systems are built. A memristor is a resistance, the conductivity of which depends on the total charge passed through it. Combining them into a matrix (crossbar) allows one layer of artificial synapses to be implemented at the hardware level. Traditionally, the STDP method based on Hebb’s rule has been used as an analog learning method. In this work, we are modeling a two-layer fully connected network with one layer of synapses. The memristive effect can manifest itself in different substances (mainly in different oxides), so it is important to understand how the characteristics of memristors will affect the parameters of the neural network. Two oxides are considered: titanium oxide (TiO2) and hafnium oxide (HfO2). For each oxide, a parametric identification of the corresponding mathematical model is performed to best fit the experimental data. The neural network is tuned depending on the oxide used and the process of training it to recognize five patterns is simulated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мемристор</kwd><kwd>оксид титана</kwd><kwd>оксид гафния</kwd><kwd>нейроморфная сеть</kwd><kwd>импульсная нейронная сеть</kwd><kwd>STDP</kwd><kwd>распознавание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>memristor</kwd><kwd>titanium oxide</kwd><kwd>hafnium oxide</kwd><kwd>neuromorphic network</kwd><kwd>impulse neural network</kwd><kwd>STDP</kwd><kwd>recognition</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РФФИ № 19-29-03051 мк.</funding-statement><funding-statement xml:lang="en">This work was supported by the RFBR grant No. 19-29-03051 MK.</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">Wong H.-S.
