GRACE: Adaptive Concept Erasure with Geometry-Guided Retention in Diffusion Models

This work proposes GRACE, a structured concept erasure framework designed to enable localized and selective intervention, and introduces a semantically weighted sensitive subspace estimation to precisely lock intervention directions, and employs lightweight subspace-constrained adapters to prevent global semantic distu...

Gaussian Core LoRA: Distribution-Aware Dynamic Adaptation for Broad Concept Erasure

Gaussian Core LoRA, a distribution-aware low-rank adaptation framework that enables prototype-adaptive erasure with a single lightweight adapter, and shows robustness to adversarial prompts, scalability to multi-identity and multi-style erasure, and compatibility with SDXL and FLUX.
