Orthogonal Concept Erasure for Diffusion Models

arXiv:2605.28902v1 Announce Type: new Abstract: Concept erasure has emerged as a promising approach to mitigate undesired or unsafe content in diffusion models, yet existing methods still face significant limitations. While training-based methods are effective, their high computational cost limits scalability. Editing-based methods are more efficient and deployment-friendly, yet they struggle to simultaneously achieve precise concept erasure and preserve overall generative capacity. We identify this core limitation of the editing-based methods as reliance on additive parameter updates. Our emp

Why this matters
Why now

The proliferation of diffusion models necessitates robust methods for content moderation and safety, driving research into efficient and effective concept erasure techniques.

Why it’s important

Improving concept erasure directly impacts the safety, reliability, and deployability of generative AI, especially in sensitive applications.

What changes

New methods for concept erasure could make diffusion models more controllable and less prone to generating undesired content, potentially influencing their broader adoption and regulatory landscape.
