Click here to .This podcast investigates best practices for enhancing Retrieval-Augmented Generation (RAG) systems, aiming to improve the accuracy and contextual relevance of language model outputs. It is based on the paper "Enhancing Retrieval-Augmented Generation: A Study of Best Practices" by Siran Li, Linus Stenzel, Carsten Eickhoff, and Seyed Ali Bahrainian, all from the University of Tübingen.The authors explore numerous factors impacting RAG performance, including the size of the language model, prompt design, document chunk size, and knowledge base size. Crucially, the study introduces novel RAG configurations, such as Query Expansion, Contrastive In-Context Learning (ICL) RAG, and Focus Mode, systematically evaluating their efficacy. Through extensive experimentation across two datasets, the findings offer actionable insights for developing more adaptable and high-performing RAG frameworks. The paper concludes by highlighting that Contrastive ICL RAG and Focus Mode RAG demonstrate superior performance, particularly in terms of factuality and response quality.For the original article click here.
