Evidence Quote

As the problem of directly working with pixels or tokens is that the objective is full of entropy. For example, text variations that does not have a right answer while all meaning roughly the same thing, and lighting changes of background within an image that doesn't even matter, but the reconstruction error will always be full of noise.
