FADE UnlearnCanvas -- Retain-only oracle (seed 0)

A retain-only oracle: Stable Diffusion fine-tuned on the 47/50 UnlearnCanvas styles that exclude Monet, Picasso, Van_Gogh (seed 0 of 3 independently-trained retain seeds). This is the reference model FADE compares an unlearned model against -- it represents 'what the model should look like if it had never seen the forget styles,' with no unlearning algorithm involved.

About FADE

FADE (Functional Alignment for Distributional Equivalence) is a metric for evaluating machine unlearning in diffusion models: it generates images from an unlearned model and a retain-only oracle, then measures a variational upper bound on the KL divergence between the two models' output distributions on those images. See the project repo for the full method and evaluation code: the project's public GitHub repo (link forthcoming)

This checkpoint is a fine-tune of Stable Diffusion v1.5, built on the UnlearnCanvas dataset/benchmark (Zhang et al., 2024). It inherits Stable Diffusion's CreativeML OpenRAIL-M license -- see the license file for the specific use-based restrictions that apply.
