Pooling types: max, mean, sum

[janetzki]

Thank you for this interactive article!

In the sentence: "No pooling type can always distinguish between graph pairs such as max pooling on the left and sum / mean pooling on the right."
"sum" should be "max".

An alternative might be to replace the image so it shows why "mean" also is not uniformly the best choice. Then, the sentence "There is no operation that is uniformly the best choice." would match the image.
