## **RAG (Retrieval-Augmented Generation)**

- RAG integrates retrieval (searching) into LLM text generation, enabling models to access external information. [✍️](https://towardsdatascience.com/rag-vs-finetuning-which-is-the-best-tool-to-boost-your-llm-application-94654b1eaba7) [25 Aug 2023]
- [Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks📑](https://arxiv.org/abs/2005.11401): Meta's 2020 framework for giving LLMs access to information beyond training data. [22 May 2020]
  - RAG-sequence — Retrieve k documents to generate all output tokens.
  - RAG-token— Retrieve k documents per token generation.
  - RAG-sequence is the industry standard due to lower cost and simplicity. [✍️](https://towardsdatascience.com/add-your-own-data-to-an-llm-using-retrieval-augmented-generation-rag-b1958bf56a5a) [30 Sep 2023]

### **Advanced RAG**

- [9 Effective Techniques To Boost Retrieval Augmented Generation (RAG) Systems✍️](https://towardsdatascience.com/9-effective-techniques-to-boost-retrieval-augmented-generation-rag-systems-210ace375049) [🗄️](9-effective-rag-techniques.png): ReRank, Prompt Compression, Hypothetical Document Embedding (HyDE), Query Rewrite and Expansion, Enhance Data Quality, Optimize Index Structure, Add Metadata, Align Query with Documents, Mixed Retrieval (Hybrid Search) [2 Jan 2024]
- Advanced RAG Patterns: How to improve RAG peformance [✍️](https://cloudatlas.me/why-do-rag-pipelines-fail-advanced-rag-patterns-part1-841faad8b3c2) / [✍️](https://cloudatlas.me/how-to-improve-rag-peformance-advanced-rag-patterns-part2-0c84e2df66e6) [17 Oct 2023]
  - Data quality: Clean, standardize, deduplicate, segment, annotate, augment, and update data to make it clear, consistent, and context-rich.
  - Embeddings fine-tuning: Fine-tune embeddings to domain specifics, adjust them according to context, and refresh them periodically to capture evolving semantics.
  - Retrieval optimization: Refine chunking, embed metadata, use query routing, multi-vector retrieval, re-ranking, hybrid search, recursive retrieval, query engine, [HyDE📑](https://arxiv.org/abs/2212.10496) [20 Dec 2022], and vector search algorithms to improve retrieval efficiency and relevance.
  - Synthesis techniques: Query transformations, prompt templating, prompt conditioning, function calling, and fine-tuning the generator to refine the generation step.
  - HyDE: Implemented in [LangChain: HypotheticalDocumentEmbedder✨](https://github.com/langchain-ai/langchain/blob/master/cookbook/hypothetical_document_embeddings.ipynb). A query generates hypothetical documents, which are then embedded and retrieved to provide the most relevant results. `query -> generate n hypothetical documents -> documents embedding - (avg of embeddings) -> retrieve -> final result.` [✍️](https://www.jiang.jp/posts/20230510_hyde_detailed/index.html)
