A number of comments here mention the regularity of the noise in the Lo variant as producing a slightly artificial appearance (zoom on the woman's forehead in picture 1). Would it improve anything to look for swathes where the dominant texture is noticeably uniform noise and mix it up a bit?

Not sure how that would work out in practice. We kind of rushed with the experiments in any case - maybe we could let the methods train for longer. In the end the adversary might learn any regular patters that appear, therefore forcing the generator to come up with something that cannot be detected easily.

(We trained everything to 1M steps. Perhaps letting it train to 2M would solve it.)
