Dr. Leon Eversberg explains how to improve the retrieval step in RAG pipelines using the HyDE technique, making LLMs more effective in accessing external knowledge through documents.
Foundational concepts, practical implementation of semantic search, and the workflow of RAG, highlighting its advantages and versatile applications.
The article provides a step-by-step guide to implementing a basic semantic search using TF-IDF and cosine similarity. This includes preprocessing steps, converting text to embeddings, and searching for relevant documents based on query similarity.

Learn how to deploy a private instance of Llama 3.2 with a Retriever-Augmented Generation (RAG) API using Lightning AI Studios, enabling you to leverage large language models in a secure and customizable environment.
The article discusses RIG, a technique that enhances AI's ability to provide more accurate and up-to-date responses by integrating LLMs with Data Commons, an open-source database of public data. It compares RIG with RAG and highlights its benefits and potential drawbacks.
"Contextual Retrieval tackles a fundamental issue in RAG: the loss of context when documents are split into smaller chunks for processing. By adding relevant contextual information to each chunk before it's embedded or indexed, the method preserves critical details that might otherwise be lost. In practical terms, this involves using Anthropic’s Claude model to generate chunk-specific context. For instance, a simple chunk stating, “The company’s revenue grew by 3% over the previous quarter,” becomes contextualized to include additional information such as the specific company and the relevant time period. This enhanced context ensures that retrieval systems can more accurately identify and utilize the correct information."
The article explains semantic text chunking, a technique for automatically grouping similar pieces of text to be used in pre-processing stages for Retrieval Augmented Generation (RAG) or similar applications. It uses visualizations to understand the chunking process and explores extensions involving clustering and LLM-powered labeling.
Archyve is a web app that enhances pretrained language models with user's documents, while keeping them on the user's own devices and infrastructure. It provides an API for querying documents, an LLM chat UI, and an API for third-party LLM chat UIs.
This article discusses the importance of chunking, embedding, and indexing in RAGs (Recursive Auto-Segmented Graphs). The author compares recursive character splitting and semantic splitting techniques for text chunking and suggests the use of agentic chunking for superior RAG retrieval.
