Pooling

http://d2l.ai/chapter_convolutional-neural-networks/pooling.html

Hi, this is a great chapter on pooling, but I think it could be made more comprehensive by also stating the explicit formula for the output dimensions just as was done for convolutions, padding and strides. What do you think?

Hi @wilfreddesert, we would like to hear more about your feedback. Could you post a suggestion/PR on how shall we improve? Please feel free to contribute!

This probably wasn’t done b/c pooling simply collapses the channel dimension
