What if the output layer of the generator is activated by "tanh" ?

[MenSanYan]

Hi, I notice that the last layer of the generator is activated by "linear", etc., the range of pixel values might stretch across (-infinite, +infinite) interval. Is there any advice or reasons for using "tanh" instead of "linear", so that pixel values is limited to (-1, +1) interval.

I remember that StyleGAN's authors have tried tanh but they did not find improvements.

I saw an explanation there looks reasonable https://github.com/taki0112/StyleGAN-Tensorflow/issues/5
