Ask Optimal Questions: Aligning Large Language Models with Retriever's Preference in Conversation

Chanwoong Yoon, Gangwoo Kim, Byeongguk Jeon +3

Conversational search, unlike single-turn retrieval tasks, requires understanding the current question within a dialogue context. The common approach of rewrite-then-retrieve aims…
