Fixed-Sequence Confidence-Interval Calibration for Finite-Sample Selective Risk Control

Selective prediction requires a statistically reliable rule for deciding which model outputs can be returned while controlling the error rate among accepted predictions. In large language model (LLM) applications, uncertainty scores provide useful ranking information, but directly thresholding such scores does not yiel...

Uncertainty-Aware Abstention in Large Language Models with Provable Alignment Guarantees

Experimental results show that CIC consistently achieves valid risk control while retaining strong answering efficiency, providing a practical and statistically grounded mechanism for deploying LLMs in reliability-sensitive QA workflows.
