Retrieval-Augmented Generation
Retrieval-augmented generation (RAG) is a technique that enhances the performance of AI models, particularly in tasks that require knowledge or data not contained within the model’s pre-trained parameters. It combines the strengths of both retrieval-based models and generative models. The retrieval component fetches relevant information from external sources, such as databases, documents, or web content, and the generative component uses this information to produce more accurate, contextually enriched responses.
RAG is implemented by integrating a retrieval mechanism with a language model. The process begins by querying a knowledge base or external resource for relevant documents or snippets. These retrieved pieces of information are then fed into the language model, which generates a response by incorporating both the prompt and the retrieved data. This approach improves the model’s ability to answer questions or solve problems with...
