Q: Is the use of the sigmoid as the activation of the last layer of a neural network theoretically justified?

AIM_BLBNeural networks are commonly used for classification tasks, in fact from this post it seems like that's where they shine brightest. When we want to classify using NNs, we just take the last layer to take values in $[0,1]$; typically, by taking the last layer to be the sigmoid function $x \maps...
