Core Concepts
LLMs can refine information for better text generation by integrating knowledge from retrieved texts and model parameters.
Abstract
Abstract introduces the concept of Retrieval-Augmented Generation (RAG) and the challenges faced by Large Language Models (LLMs).
Proposal of a novel perspective considering LLMs as "Information Refiner" to generate concise, accurate, and complete texts.
Introduction explains the application of RAG in modern NLP systems and the need for LLMs to utilize retrieved information effectively.
Detailed explanation of the proposed method INFO-RAG for unsupervised training of LLMs for RAG.
Extensive experiments across various tasks show significant improvement in LLaMA2 performance with INFO-RAG.
Related work discusses existing methods for retrieval-augmented generation and unsupervised learning in RAG.
Detailed explanation of INFO-RAG methodology, including data extraction, training tasks, and training strategy.
Results showcase the performance improvement of LLaMA2 with INFO-RAG across different datasets and tasks.
Analysis includes fine-grained analysis for three RAG scenarios, ablation study, robustness to retrieval results, and avoidance of catastrophic forgetting.
Conclusion summarizes the key findings and limitations of the study.
