RAG - Vector DB

What is a Vector Database? A vector database is a database used to store vectors (points in space) where data with similar meanings are positioned close together. These vectors are generated using embedding models or LLM embedding models. One of the embedding models is nomic-embed-text . We can download this model using Ollama. Why Vector DB in RAG? One-hot encoding is a technique used to convert categorical data (like words) into binary vectors. How it works: Each unique word in a vocabulary is
