Forget Many, Forget Right: Scalable and Precise Concept Unlearning in Diffusion Models

Bo Hui, Gen Li, Kaiyuan Deng, Xiaolong Ma, Yang Xiao

ScaPre gives diffusion models a closed-form way to unlearn many concepts at once by isolating relevant parameters and stabilizing updates.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

ScaPre yields an efficient closed-form solution without requiring auxiliary data or sub-models. It forgets up to ×5 more concepts than the best baseline within acceptable quality limits, achieving state-of-the-art precision and efficiency for large-scale unlearning.

C2weakest assumption

That the Informax Decoupler can accurately identify concept-relevant parameters and strictly confine updates to the target subspace without collateral damage, and that spectral trace regularization plus geometry alignment fully resolve conflicting weight updates across large numbers of concepts.

C3one line summary

ScaPre delivers a closed-form method for precise large-scale multi-concept unlearning in diffusion models that removes up to five times more concepts than prior baselines while preserving image quality.
