Trust but Verify: Prover-Verifier Deliberation for Selective LLM Prediction
The paper introduces a new protocol called prover-verifier deliberation (PVD) for improving the reliability of language model predictions. This protocol allows a system to provide both answers and confidence levels, enabling it to report high-confidence responses while abstaining from uncertain ones. The authors empirically evaluate the protocol's effectiveness and highlight its potential advantages over existing methods.
- ▪Prover-verifier deliberation (PVD) is an inference-time protocol designed for selective prediction in language models.
- ▪The protocol produces both an answer and a structured confidence verdict, allowing for high-confidence reporting.
- ▪Empirical evaluations show that PVD can effectively separate reliable from unreliable answers.
