The approach reduces standard error by 21% on the ESCI benchmark and correctly identified the best system variant in a production environment, confirmed by A/B testing showing a +407 basis point increase in daily sales.", "body_md": "arXiv:2606.05308v1 Announce Type: new\nAbstract: With PRECISE, we extended Prediction-Powered Inference to produce bias-corrected estimates of ranking evaluation metrics by combining a small human-labeled set with a large LLM-judged set. PPI is provably unbiased regardless of the LLM judge's error profile. We make it applicable to hierarchical metrics like Precision@K, where annotations are per-document but the metric is per-query, by reducing the output-space computation from O(2^|C|) to O(2^K). On the ESCI benchmark, augmenting 30 human annotations with Claude 3 Sonnet judgments reduces the standard error of Precision@4 estimates from 4.45 to 3.50 (a 21% relative reduction). In a production system, our framework correctly identified the best of three system variants from 100 human labels and 2 hours of domain-expert annotation; A/B testing confirmed this ranking with +407 bps in daily sales.", "url": "https://wpnews.pro/news/statistically-reliable-llm-based-ranking-evaluation-via-prediction-powered", "canonical_source": "https://arxiv.org/abs/2606.05308", "published_at": "2026-06-05 04:00:00+00:00", "updated_at": "2026-06-05 04:37:40.409451+00:00", "lang": "en", "topics": ["large-language-models", "machine-learning", "artificial-intelligence", "ai-research"], "entities": ["PRECISE", "Prediction-Powered Inference", "Claude 3 Sonnet", "ESCI"], "alternates": {"html": "https://wpnews.pro/news/statistically-reliable-llm-based-ranking-evaluation-via-prediction-powered", "markdown": "https://wpnews.pro/news/statistically-reliable-llm-based-ranking-evaluation-via-prediction-powered.md", "text": "https://wpnews.pro/news/statistically-reliable-llm-based-ranking-evaluation-via-prediction-powered.txt", "jsonld": "https://wpnews.pro/news/statistically-reliable-llm-based-ranking-evaluation-via-prediction-powered.jsonld"}}
