I am a first-year graduate student at the Engineering Research Center of Digital Forensics, Ministry of Education, School of Computer Science, Nanjing University of Information Science and Technology (NUIST), under the guidance of Prof. Zhangjie Fu. I obtained my Bachelor’s degree from NUIST. My research is focused on AIGC detection and AI security.

📝 Publications
Dual Frequency Branch Framework with Reconstructed Sliding Windows Attention for AI-Generated Image Detection.pdf. Github.
Jiazhen Yan, Ziqiang Li, Fan Wang, Ziwen He, Zhangjie Fu.
- We utilize a sliding window to restrict the attention mechanism to a local window, and reconstruct the features within the window to model the relationships between neighboring internal elements within the local region.
DGS-Net: Distillation-Guided Gradient Surgery for CLIP Fine-Tuning in AI-Generated Image Detection.pdf. Github.
Jiazhen Yan, Ziqiang Li, Fan Wang, Boyu Wang, Ziwen He, Zhangjie Fu.
- We introduce a novel gradient-space decomposition that disentangles CLIP representations into transferable pre-trained priors and task-irrelevant components.
