Hitting a Moving Target: Test-Time Adaptation for AI Text Detection under Continual Distribution Shift

Researchers propose a test-time adaptation approach using semi-supervised learning to detect AI-generated text despite continual distribution shifts post-deployment, such as adversarial humanization attempts, new LLM releases, and temporal changes in human writing patterns. The method achieves 90.5% detection of adversarial AI text compared to 24.1% for commercial detectors, suggesting a more robust framework for real-world AI text detection.
