COIN: Uncertainty-Guarding Selective Question Answering for Foundation Models with Provable Risk Guarantees

2025 · arXiv (Cornell University)

Uncertainty quantification (UQ) for foundation models is essential to identify and mitigate potential hallucinations in automatically generated text. However, heuristic UQ approaches lack formal guarantees for key metrics such as the false discovery rate (FDR) …
