Need We Teach Foundation Models What is a Generative Image? Gradient-Free Generative Artifact Detection via Analytic Spectral Adaptation

arXiv:2606.07660v1 Announce Type: cross Abstract: Adapting foundation models to detect generative artifacts via gradient-based updates compromises their intrinsic representations. Under optimization on limited samples, models overfit to local domain shortcuts. Fine-tuning massive weights on specialized data introduces erroneous inductive biases, inducing a measurable $\mathcal{L}_2$ norm perturbation in the high-dimensional feature space -- a phenomenon we formalize as anchor drift. Amplified by nonlinear activations, this drift impairs zero-shot forgery detection across unseen domains.We prop
The proliferation of generative AI necessitates robust and efficient methods for artifact detection, and this research proposes a novel gradient-free approach.
This research provides a method for generative artifact detection that does not compromise foundation model integrity, crucial for maintaining trust and reliability in AI-generated content.
The ability to detect generative artifacts without fine-tuning could lead to more stable and adaptable detection systems, improving the robustness of AI safety measures.
