Researchers have developed PE-Mamba, a new framework designed to improve the detection of AI-generated images. This system utilizes a pre-trained PE-Core vision transformer with LoRA adaptation and introduces three novel components for feature aggregation. These include a bidirectional selective aggregator for processing layer-wise classification tokens, a softmax-weighted aggregator for a learned global summary, and a sigmoid-gated blend to dynamically fuse the outputs of the other two. Experiments show PE-Mamba outperforms existing detectors on benchmark datasets like UniversalFakeDetect and AIGCDetect, demonstrating strong generalization capabilities across various generative models while requiring minimal parameter training.
