back-propagation neural network

back-propagation neural network
[lang name="English"]back-propagation neural network, BPNN
нейронная сеть с обратным распространением
разновидность многослойных нейронных сетей, в которой обучение реализуется методом обратного распространения выходной ошибки на веса промежуточных нейронов; коррекция весов проводится в цикле по набору образцов, пока не будет достаточно минимизировано отклонение выходных значений от желаемых; нейронные сети используются для автоматизированной классификации изображений
