Building an advanced local LLM RAG pipeline with hypothetical document embeddings Dr. Leon Eversberg · Follow Published in Towards Data Science · 9 min read · 7 hours ago — Implementing HyDE is very simple in Python. Image by the author Large Language Models (LLMs) can be improved by giving them access to external knowledge through documents. The basic Retrieval Augmented Generation (RAG) pipeline consists of a user query, an embedding model that converts text

A deep dive into stochastic decoding with temperature, top_p, top_k, and min_p Dr. Leon Eversberg · Follow Published in Towards Data Science · 10 min read · 11 hours ago — When calling the OpenAI API with the Python SDK, have you ever wondered what exactly the temperature and top_p parameters do? When you ask a Large Language Model (LLM) a question, the model outputs a probability for every possible token in its vocabulary. After

Building an advanced local LLM RAG pipeline by combining dense embeddings with BM25 Dr. Leon Eversberg · Follow Published in Towards Data Science · 11 min read · 12 hours ago — Code snippet from the hybrid search we are going to implement in this article. Image by author The basic Retrieval-Augmented Generation (RAG) pipeline uses an encoder model to search for similar documents when given a query. This is also called semantic search because
