DoPR framework boosts LLM reranking efficiency with compressed document prefixes

By PulseAugur Editorial · [1 sources] ·

Researchers have developed DoPR, a novel framework designed to enhance the efficiency of Large Language Model (LLM) reranking. DoPR addresses the issue of redundant document processing by decoupling offline document preparation from online reranking. It achieves this by creating reusable, compressed document prefix states that are precomputed and stored. During online reranking, LLMs only need to process the query and a scoring token, utilizing the stored prefixes for document information, which significantly reduces computational costs and latency. AI

IMPACT This framework could significantly reduce the computational resources required for LLM-based search and retrieval systems, making them more scalable and cost-effective.

    DoPR: Reusable Compressed Document Prefixes for Efficient LLM Reranking

    Large language models (LLMs) are effective rerankers, but pointwise reranking repeatedly processes the same document across different queries, causing substantial redundant document-side computation. We propose \textbf{DoPR}, a compressed document prefix framework that decouples …
