Обучение формулируется как задача оптимизации, решаемая с помощью градиентного спуска с учетом его особенностей в многомерных пространствах параметров. Описываются роль размеченных данных, влияние размера батча и организации эпох на процесс обучения. Поясняется применение метода обратного распространения ошибки для эффективного вычисления градиента в сложных архитектурах нейросетей</p></abstract><abstract xml:lang="en" abstract-type="summary"><p>This paper examines the mathematical foundations of neural network training through minimizing the loss function as a measure of model quality. Training is formulated as an optimization problem solved using gradient descent, taking into account itsspecific features in multidimensional parameter spaces. The role of labeled data, the influence of batch size, and epoch organization on the training process are described. The application of the backpropagation method for efficient gradient computation in complex neural network architectures is explained</p></abstract><kwd-group xml:lang="ru"><kwd>нейронные сети</kwd><kwd>функция потерь</kwd><kwd>лосс</kwd><kwd>градиентный спуск</kwd><kwd>оптимизация</kwd><kwd>машинное обучение</kwd><kwd>обучение с учителем</kwd><kwd>обучение безучителя</kwd><kwd>разметка данных</kwd><kwd>батч</kwd><kwd>эпоха</kwd><kwd>градиент</kwd><kwd>частная производная</kwd><kwd>обратное распространение ошибки</kwd><kwd>слои нейросети</kwd><kwd>прямой и обратный ход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neural networks</kwd><kwd>loss function</kwd><kwd>loss</kwd><kwd>gradient descent</kwd><kwd>optimization</kwd><kwd>machine learning</kwd><kwd>supervised learning</kwd><kwd>unsupervised learning</kwd><kwd>data labeling</kwd><kwd>batch</kwd><kwd>epoch</kwd><kwd>gradient</kwd><kwd>partial derivative</kwd><kwd>backpropagation</kwd><kwd>neural network layers</kwd><kwd>forward and backward progression</kwd></kwd-group></article-meta></front><back><ref-list><ref id="ref1"><mixed-citation publication-type="other" xml:lang="ru">Hanson A., Koutilya PNVR, Sanjukta Krishnagopal, Larry Davis Bidirectional Convolutional LSTM for the Detection of Violence in Videos. 2018.
