The authors use sparse autoencoders, tools that decompose internal neural-network activations into a small set of active features, to identify features associated with a target concept.
Targeted feature edits improve concept removal from image diffusion models
ConceptACP uses sparse autoencoders to guide localized fine-tuning, reporting a 36.34-percentage-point average improvement in forgetting success on SDXL-Turbo.
