Which Metrics Save the Most Human Annotation? Prediction-Powered Evaluation and Meta-Evaluation

The paper introduces prediction‑powered evaluation, a framework that blends limited human judgments with large‑scale automatic scores to produce unbiased, data‑efficient system comparisons. It offers both parametric and non‑parametric methods, examines the trade‑off between paired and unpaired designs, and validates the approach on six WMT datasets. Additionally, the authors propose the Prediction‑Powered Saving Ratio (PPSR), a meta‑metric that quantifies how much human annotation can be saved by using an automatic metric within this framework, providing more discriminative and stable metric rankings than existing system‑level meta‑metrics.

BACON: Budgeted Human Calibration for Modeling and Evaluation with Multiple AI Judges

arXiv:2607. 16239v1 Announce Type: new Abstract: AI judges offer a scalable, low-cost alternative to human evaluation, but their outputs can be biased relative to human preferences and highly item-dependent, varying across judges, tasks, and domains.

Aggregate-then-Calibrate for Human-centered Assessment with Theoretical Guarantees

Human-centered assessment tasks, which are essential for systematic decision-making, rely heavily on human judgment and typically lack verifiable ground truth. Existing approaches face a dilemma: methods using only human judgments suffer from heterogeneous expertise and inconsistent rating scales, while methods using only model-generated scores must learn from imperfect proxies or incomplete features.

Prediction-Powered Smoothing and Validation for Disaggregated AI Evaluation

The paper introduces prediction‑powered smoothing (PP‑S) and its taxonomy‑aware extension (PP‑TS) to improve point and interval estimates of domain‑specific AI performance when only a limited sample of labeled units is available. It also proposes a new design‑based cross‑validation score that is approximately unbiased for selecting between direct and smoothed estimators. Experiments on a curated benchmark and real‑world agent traffic show that the proposed methods outperform direct estimators in both accuracy and coverage, and that the new score matches the performance of an independent validation sample while providing more precise error estimates.

DualEval: Joint Model-Item Calibration for Unified LLM Evaluation

arXiv:2606. 26429v1 Announce Type: new Abstract: Current LLM evaluation relies on two complementary but often disconnected signals: static benchmarks with objective correctness labels and arena-style preference data that better reflect open-ended user interactions.
