Need We Teach Foundation Models What is a Generative Image? Gradient-Free Generative Artifact Detection via Analytic Spectral Adaptation
Researchers have developed a novel gradient-free method to detect generated images by treating detection as an out-of-distribution anomaly measurement problem. This approach reframes the task to avoid compromising the intrinsic representations of foundation models, which can occur with traditional gradient-based updates. The technique establishes a stable anchor on the real visual manifold by analytically decoupling statistical and semantic deviations, significantly outperforming gradient-optimized methods in zero-shot settings.
