Web9 de out. de 2024 · 3. Backpropagation is a very general algorithm can be applied anywhere where there is a computation graph on which you can define gradients. Residual networks, like simple fully connected networks, are computation graphs on which all the operations are differentiable and have mathematically defined gradients. 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.
