- Hierarchical Document Refinement for Long-context Retrieval-augmented Generation (2025 · 25 citations)
Retrieval-augmented generation (RAG) often feeds an LLM very long retrieved documents. These texts carry much irrelevant material, which raises inference cost and lowers answer quality. Existing compressors either target short chunks or rank tokens with crude signals such as perplexity, so they ignore how a document… - RetroLLM: Empowering Large Language Models to Retrieve Fine-grained Evidence within Generation (2025 · 19 citations)
RetroLLM targets three weaknesses of standard retrieval-augmented generation (RAG): the cost of running a separate retriever, long inputs padded with redundant retrieved chunks, and the fact that retrieval and generation cannot be optimized together.
