Hello!

I am on this slide right now (I hope you can see the screenshot - it is on 10:44, when we compute number of operations for pointwise multiplication).

It seems like when we calculate the first layer of the result stack (on the right) we are using 2 vectors: 1x1x3 from the input and 1x1x3 from the filter.

When we calculate the second layer, we again use the same 2 vectors.

So as far as I can see all the layer of the output will be the same as they are calculated using the same vectors.

The question is: can we skip the multiplications we do not need and just copy the values from the first layer?
