How to Use Re-Ranking for Better LLM RAG Retrieval

Building an advanced local LLM RAG pipeline with two-step retrieval using open-source bi-encoders and cross-encoders

An image of an advanced RAG pipeline with two-step retrieval. First, a bi-encoder is used to find similar embedding vectors. Then, a cross-encoder model is used to narrow these candidates down to the top k most relevant documents.

Beyond Vector Search: Structure-Aware RAG With STAIR And Jev

How table-of-contents-based retrieval can guide LLMs to the right section

Workflow diagram divided into two steps: Input Preparation and Inference. Input Preparation shows a Book (PDF) leading to ToC Extraction. An arrow leads to the Inference stage, where Query Input and ToC feed into Jev, followed by Constrained Generation, and outputting to a Predicted Leaf Node.
