Retrieval Augmented Generation

Retrieval Augmented Generation(RAG) is a framework that combines elements of information retrieval and natural language generation. It aims to enhance the content generation process by incorporating relevant information retrieved from a pre-existing knowledge base. In the context of language models, like GPT-3.5, this approach helps generate more accurate and contextually relevant responses.

In RAG, the model is equipped with the ability to access and retrieve information from external knowledge sources, such as a large database or document collection. This retrieval step provides the model with context and factual information to support the generation of more informed and contextually appropriate responses.

The key steps in Retrieval Augmented Generation typically involve:

  • Retrieval: The model searches a knowledge base for relevant information related to the input or query.
  • Integration: The retrieved information is integrated into the model's understanding, providing context and grounding for subsequent generation.
  • Generation: The model generates a response considering both the input and the retrieved information, resulting in more contextually relevant and accurate output.

This approach is particularly useful in scenarios where the model needs access to external information for better contextual understanding and factual accuracy. RAG has been applied in various natural language processing tasks, such as question answering, dialogue systems, and content creation, to improve the quality and relevance of generated content.
