Some questions about the proposed clustering-based prompts.

[dayuyang1999]

Dear Authors

Thanks for sharing the great work.

For the proposed Clustering-based prompts, I have a few question: Q1: Step 1: get 1 initial document per question. Wondering why we need to have this step? Seems not benefit to increase diversity? Q2: Step 2: title said "encoding documents", paragraph said "encode question-document pair"; wondering what do you actually encoding? Q3: Step 3: Sampling K question-doc paris from K-clusters; How to make sure the document contains relevant information to the question? Q4: So the intuition of this method is: like in-context learning, providing an "prompt example" for LLM to generate diverse documents; and then giving the sample instruction, the LLM will generate documents with high diversity?

thanks for your attention!

Best, Dayu
