New research details methods for detecting AI benchmark contamination

A new research paper explores the detectability of benchmark contamination in AI models. The study introduces a formal framework to distinguish between a clean benchmark and an audit with insufficient power. It proposes a method using the mixture Q_alpha, where alpha represents the fraction of seen items, and shows that detectability depends on alpha, rho (behavioral separability), and the number of samples (m). The research also highlights that while calibration efficacy predicts power curves, the Gaussian budget can be miscalibrated at small sample sizes, suggesting a need for a two-stage planner to repair budgets and ensure validity.
