Stable Diffusion checkpoints after applying Concept Ablation (CA) (CA reference implementation) to unlearn a single artistic style from the UnlearnCanvas full (50-style) checkpoint. One checkpoint per forgotten style.

These checkpoints were evaluated with FADE against the retain-only oracle checkpoints (see sungjuncho/fade-unlearncanvas-retain-seed{0,1,2}) and with UnlearnCanvas's own accuracy/FID metrics. See the project repo for numbers and evaluation scripts.

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.
