arXiv:2606. 00392v1 Announce Type: cross Abstract: AI-text detectors are vulnerable to paraphrasing and detector-guided paraphrasing attacks, but existing detector-evasion methods often lack precise control over semantic preservation.
arXiv:2608. 05430v1 Announce Type: cross Abstract: The remarkable instruction-following ability of modern LLMs has enabled their practical use as the minds of agents that can autonomously complete increasingly complex tasks.
The paper introduces Pattern Stability Score (PSS), a watermark detection framework that uses local statistical features and stability dynamics across paraphrased variants to identify machine-generated text. PSS combines global and local z‑score features with higher‑order run‑length statistics, autocorrelation signals, and stability scores over paraphrase depth. Experiments on PG‑19, CNN/DailyMail, and WikiText with Llama‑3‑8B, Qwen2‑7B, and multiple paraphrasers show that PSS improves detection AUC by 10‑15 percentage points and a single universal classifier achieves over 87.8% AUC across diverse LLMs, paraphrasers, and domains without retraining.

The paper introduces MOSAIC, a large adversarial benchmark for detecting AI-generated text, and presents NeuroStat, a new framework that combines token‑level probabilistic logits with deep semantic hidden states from a single language model. NeuroStat fuses these signals via Macro‑State Residual Modulation and uses orthogonal and contrastive losses to learn complementary representations. Experiments show that NeuroStat outperforms existing methods on MOSAIC, achieving superior robustness against adversarial attacks.
