C2W1 Graded Quiz

could anyone explain to me why this is incorrect ?

Iā€™m guessing that you are thinking of convolution, not pooling. Pooling works differently.

Additional to @bs80 response. The pooling operation reduces the spatial dimensions of the input image by a factor of the pool size. In this case, the pool size is 2x2, so the resulting image will have half the height and half the width of the input image.

Hopefully, help :hugs:
