[Question] Pre-computed unconditional embeddings
BlenderNeko opened this issue · comments
I noticed that the assets folder contains some pre-computed embeddings that function as the unconditional input. Were these computed similarly to how the graido app uses black images to provide the unconditional embedding?
Although we provide assets/clip_ug.pth, we didn't actually use that. The UG for prompt-free diffusion is all zeros vectors.
But prompt-free is totally fine with traditional UG (i.e. negative prompts), you may try use it. Our experience shows little improvement.
The anime app, however, assets/anime_ug.pth provided improvement in results, so we apply that in the app.
