The paper investigates patch‑wise supervision for detecting AI‑generated images, proposing a shared backbone that classifies explicit crops with individual losses and averages patch probabilities only during inference. This approach eliminates the need for handcrafted residual filtering or learned image‑level fusion modules. Experiments across single‑patch selection, multiple generator collections, and four CNN and Transformer backbones show that patch‑wise variants outperform whole‑image counterparts on the GenImage dataset, while also exploring factors such as supervision granularity, source resolution, crop size, and inference coverage.

The paper introduces Relative Patch Response Learning (PRL) to detect AI‑generated images by comparing patch responses across two mixed views of aligned real‑generated image pairs. PRL uses a relative response objective, a reference coherence objective, and an area ranking objective to address contextual shifts caused by self‑attention, providing precise supervision for patch‑level detection. Experiments show PRL outperforms prior methods by 4.3% and 5.9% in average balanced accuracy on standard and in‑the‑wild benchmarks.

The paper investigates whether pretrained language models can act as lightweight auxiliary supervision for supervised vision training, without requiring paired image-text data or complex objectives. Two forms of language guidance—Explicit Language Guidance (ExLG) and Implicit Language Guidance (ImLG)—are evaluated across six generalization regimes, including in‑distribution, out‑of‑distribution, shortcut resistance, texture/shape bias, adversarial robustness, and continual learning. Results show that ExLG improves in‑distribution, low‑data performance, and continual learning retention, while ImLG is more effective in shortcut‑sensitive and adversarial settings, and both add minimal parameters and training overhead.
