Nvidia researchers have developed a new AI image generation technique that could allow highly customized text-to-image models with a fraction of the storage requirements.
According to a paper published on arXiv, the proposed method called “Perfusion” enables adding new visual concepts to an existing model using only 100KB of parameters per concept.
As the paper’s authors describe, Perfusion works by “making small updates to the internal representations of a text-to-image model.”
More specifically, it makes carefully calculated changes to the parts of the model that connect the text descriptions to the generated visual features. Applying minor, parameterized edits to the cross-attention layers allows Perfusion to modify how text inputs get translated into images.
Therefore, Perfusion …
