Dive in.
Understanding RAG: What is it?
Retrieval-Augmented Generation (RAG) is a cutting-edge technology used in natural language processing (NLP) and information retrieval systems.
It combines two fundamental processes: retrieval and generation.
Retrieval: In RAG, the retrieval process involves fetching relevant data from various external sources such as document repositories, databases, or APIs. This external data can be diverse, encompassing information from different sources and formats.
Generation: Once the relevant data is retrieved, the generation process involves creating or generating new content, insights, or responses based on the retrieved information. This generated content complements the existing data and aids in decision-making or providing accurate responses.
How does RAG work?
Now, let’s understand how RAG works.
Data preparation
The initial step involves converting both the documents stored in a collection and the user queries into a comparable format. This step is crucial for performing similarity searches.
Numerical representation (Embeddings)
To make documents and user queries comparable for similarity searches, they are converted into numerical representations called embeddings.
These embeddings are created using sophisticated embedding language models and essentially serve as numerical vectors representing the concepts in the text.
Vector database
The document embeddings, which are numerical representations of the text, can be stored in vector databases like Chroma or Weaviate. These databases enable efficient storage and retrieval of embeddings for similarity searches.
Similarity search
Based on the embedding generated from the user query, a similarity search is conducted in the embedding space. This search aims to identify similar text or documents from the collection based on the numerical similarity of their embeddings.
Context addition
After identifying similar text, the retrieved content (prompt + entered text) is added to the context. This augmented context, comprising both the original prompt and the relevant external data, is then fed into a Language Model (LLM).
Model output
The Language Model processes the context with relevant external data, enabling it to generate more accurate and contextually relevant outputs or responses.
