The pooling layer in the convolutional neural network can reduce the size of the lower layer input. Common pooling is:

In the deep learning network, the backpropagation algorithm is used to find the optimal parameters. What rules are used in the backpropagation algorithm to obtain the derivation layer by layer?

Image label service returned tag There can be more than one.
