Web9 de out. de 2024 · Back-propagation works in a logic very similar to that of feed-forward. The difference is the direction of data flow. In the feed-forward step, you have the inputs and the output observed from it. You can propagate the values forward to train the neurons ahead. In the back-propagation step, you cannot know the errors occurred in every …
WebBackpropagation works in convolutional networks just like how it works in deep neural nets. The only difference is that due to the weight sharing mechanism in the convolution process, the amount of update applied to the weights in the convolution layer is also shared. Share.
