Chain-of-Verification
Also called CoVe.
Chain-of-Verification (CoVe) reduces hallucination by having the model draft an answer, plan verification questions about its claims, answer those questions independently, and then produce a corrected final answer.
Description
Answering the verification questions without seeing the original draft keeps the model from simply repeating its own errors.
