Breaking Down RAG (Retrieval Augmented Generation)

To get a handle on RAG, let’s break it down into its two main parts: retrieval models and generative models.

Retrieval Models: These models are great at digging up relevant info from a set of documents or a knowledge base. They use techniques like information retrieval or semantic search to find the most pertinent pieces of information based on a query. Think of them as your go-to for accurate and specific information, but not so much for creating new content.

Generative Models: On the flip side, generative models are all about creating new content from a given prompt. These large language models (LLMs) learn the patterns and structures of natural language from tons of training data. They’re your go-to for creative and coherent text, though they might miss the mark on factual accuracy or relevance sometimes.

How RAG Works

Now, RAG steps in to blend these two approaches and cover their individual weaknesses. Here’s how it works: a retrieval-based model first fetches relevant info from a knowledge base or documents based on a query. This retrieved info then feeds into the generative model, giving it a solid foundation to build on.

By using this method, the generative model can leverage the accuracy and specificity of the retrieval model. This helps it stay grounded in real, available knowledge, resulting in text that’s both relevant and accurate.

More on Retrieval Models

Retrieval models are designed to find and rank relevant information in response to a query. They benefit from large datasets and are trained to produce meaningful, context-specific results. One popular retrieval model is Neural Network Embeddings. It calculates how well documents rank against your query based on the calculated distance in a vector space (hence the use of vector databases)

Applications of RAG

RAG has tons of cool applications. For instance, in question-answering systems, the retrieval model finds relevant passages or documents, and the generative model crafts a concise and coherent answer. In content creation, such as summarization or story writing, the retrieval model provides relevant facts or context, which the generative model uses to make the content more informative and engaging.

So what?

In a nutshell, RAG marries the strengths of retrieval-based and generative models to enhance the quality and relevance of generated text. By combining the accuracy of retrieval models and the creative power of generative models, RAG creates more robust and contextually grounded language generation systems. So, you get the best of both worlds—accurate and creative text generation.
