Why paired image for sketch is ground truth in loss function?

[lllyasviel]

V(x) is shaped as 1x1x4096
G(x, y) is shaped as 256x256x3 or 512x512x3
you can not make diff for them.
v(x) is style of x
G(x, y) , y = v(x) means "use sketch of x and style of x to generate x itself."
When the dataset is large enough, it somehow works like style transfer.

From my understanding, the sketch isn't necessary? If you decrease the input to content & style, you can still get the *style transfer* done.

maybe and you can try

I'm still not quite follow why you use `y`(sketch-paired image) as the ground truth in this case? Can you explain a bit more? Thank you!
