This study addresses the challenge of tracing generative pipelines in AI-driven influence operations by constructing Propagia, the first French propaganda corpus. By integrating topic modeling, sentiment analysis, prompt leakage detection, and rewriting-based attribution techniques, this work reverse-engineers the content generation process. The research reveals distinct stylistic characteristics of AI-generated propaganda, identifies evidence of prompt leakage across 50 websites, and successfully attributes generated content to Llama-3 and Mistral models. Collectively, these findings establish a systematic methodological framework for the forensic analysis and provenance identification of AI-generated content, offering critical insights into detecting and mitigating automated disinformation campaigns.
In distributed quantum computing, logical states encoded in continuous-variable Gottesman–Kitaev–Preskill (GKP) codes face significant challenges in achieving high-fidelity fusion via passive linear optics due to finite squeezing and entanglement-induced decoherence. This work proposes an active, measurement-based protocol that leverages auxiliary GKP Bell states, homodyne detection, and feedforward control to implement a completely positive trace-preserving map preserving the geometric structure of the logical code space. The protocol enables, for the first time, homomorphic logical addition of GKP states across multiple nodes. It further exhibits approximate quantum non-demolition characteristics, rigorously bounds information leakage under one-time-pad encryption, and derives an analytical upper bound on logical fidelity under finite squeezing. These results demonstrate the scheme’s ability to simultaneously suppress decoherence and information leakage while effectively preserving logical information integrity.
This work addresses the lack of spatial uncertainty modeling in YOLO-Pose for keypoint localization. The authors propose a lightweight, post-hoc probabilistic extension that introduces an additional probability head to predict input-dependent 2×2 covariance matrices, enabling calibrated bivariate Gaussian or Student-t distributions over original keypoints. This is the first approach to equip YOLO-Pose with keypoint-level predictive distributions. A novel evaluation protocol is introduced, combining distribution calibration diagnostics with Average Keypoint Precision (AKP). Experiments on COCO demonstrate that the method effectively supports reliability-based keypoint ranking, with the Student-t formulation yielding more accurate residual distribution fitting. Furthermore, in an aircraft visual landing task, the calibrated covariance enables uncertainty-aware pose estimation and sensor fusion.
