Rel-Zero: Harnessing Patch-Pair Invariance for Robust Zero-Watermarking Against AI Editing
Pengzhen Chen, Yanwei Liu, Xiaoyan Gu +3
Recent advancements in diffusion-based image editing pose a significant threat to the authenticity of digital visual content. Traditional embedding-based watermarking methods often…
Rotation-Invariant Spherical Watermarking via Third-Order SO(3) Representation Coupling
Pengzhen Chen, Yanwei Liu, Xiaoyan Gu +3
Reliable watermarking of panoramic imagery is fundamentally challenged by arbitrary 3D rotations. As panoramas are defined on the sphere, they naturally transform under the action…
RumorSphere: A Framework for Million-scale Agent-based Dynamic Simulation of Rumor Propagation
Yijun Liu, Wu Liu, Xiaoyan Gu +4
Rumor propagation modeling is critical for understanding and mitigating misinformation. Existing approaches combining rule-based regular agents with LLM-driven core agents provide…
PopSim: Social Network Simulation for Social Media Popularity Prediction
Yijun Liu, Wu Liu, Xiaoyan Gu +3
Accurately predicting the popularity of user-generated content (UGC) is essential for advancing social media analytics and recommendation systems. Existing approaches typically fol…
