WebThe weights are updated right after back-propagation in each iteration of stochastic gradient descent. From Section 8.3.1: Here you can see that the parameters are updated by multiplying the gradient by the learning rate and subtracting. The SGD algorithm described here applies to CNNs as well as other architectures. http://whatastarrynight.com/machine%20learning/python/Constructing-A-Simple-CNN-for-Solving-MNIST-Image-Classification-with-PyTorch/
