Can Convolutional Neural Networks (cnn) Be Represented By A Mathematical Formula?

Please, let me know if this question should be posted in a differnt stack such as the https://datascience.stackexchange.com/. Let's say that I already trained my CNN. Is there anyw

Solution 1:

If you can sacrifice some memory, you can certainly convert a convolution into a matrix multiplication.

It turns out to have its own pros (faster than any trivial implementation unless you optimize really seriously) and cons (large memory consumption).
