New research quantifies LLM watermark estimation complexity · arXiv

By PulseAugur Editorial · [3 sources] ·

A new research paper explores the complexities of estimating the proportion of text generated by large language models (LLMs) using Gumbel-Max watermarking. The study compares two observation regimes: full observation and a more prevalent pivotal reduction method. Researchers developed estimators for both, establishing matching information-theoretic lower bounds for sample complexity. The findings suggest that while pivotal reduction is elegant, it may not always be the most sample-efficient approach for watermark proportion estimation. AI
