AttnMod: Attention-Based New Art Styles

Imagine a human artist looking at the generated photo of a diffusion model, and hoping to create a painting out of it. There could be some feature of the object in the photo that the artist wants to emphasize, some color to disperse, some silhouette to twist, or some part of the scene to be materialized. These intentions can be viewed as the modification of the cross attention from the text prompt onto UNet, during the desoising diffusion. This work presents AttnMod, to modify attention for creating new unpromptable art styles out of existing diffusion models. The style-creating behavior is studied across different setups.
