【The Basics of RAG】Explaining Techniques to Improve the Accuracy of Generative AI!

Are you familiar with RAG (Retrieval Augmented Generation), which is garnering attention in the field of generative AI? RAG is the latest technology designed to enhance the accuracy of responses from LLMs (Large Language Models), and major cloud vendors such as AWS and Azure are advancing its implementation. By understanding the mechanism of RAG, it is possible to generate high-quality answers that surpass those of ChatGPT. This article will provide a detailed explanation of RAG’s basic mechanisms, specific applications, and examples.


Overview of RAG

Basic Principles of RAG

RAG (Retrieval Augmented Generation) is a groundbreaking technology that significantly enhances the accuracy of generative AI responses. This technology is based on a unique mechanism that improves the quality of answers provided by Large Language Models (LLMs) by skillfully incorporating information from external databases and knowledge bases. 

Specifically, in response to user queries, RAG dynamically searches for relevant external information and restructures the answer based on this information. Through this process, generative AI can provide more accurate responses, sometimes based on the latest information.

For instance, AWS uses this innovative technology to base responses of models like ChatGPT on specific data and facts. In Azure’s services, RAG is used to generate customized responses based on specific corporate knowledge. Moreover, Oracle has also implemented RAG to significantly enhance the accuracy of responses to business-specific questions.

As these examples illustrate, RAG maximizes the potential of generative AI and LLMs, significantly expanding the scope and precision of their responses. Notably, RAG has become an accessible technology for a broader range of developers through major platforms like AWS and Azure. This makes RAG a promising and appealing technology for engineers with experience in developing with the ChatGPT API or Azure OpenAI Service.

Key Technical Elements and Functions of RAG

The core technological elements of RAG (Retrieval Augmented Generation) lie in the mechanisms for searching and integrating external information. This innovative technology significantly enhances the quality of responses generated by AI by identifying the most relevant information to a specific query and skillfully integrating it into the knowledge system of an LLM (Large Language Model). RAG’s functionality includes improving the precision and timeliness of information, which makes the responses it generates more specific and reliable.

One notable role of RAG is its ability to expand the existing knowledge base of an LLM and make new sources of information available. For example, AWS uses RAG to extract the latest information from cloud-based databases, and Azure utilizes it to generate customized responses in cooperation with company-specific knowledge bases. Moreover, Oracle uses RAG to provide answers specialized to certain industries or fields, thus greatly expanding the applicability of generative AI.

Furthermore, RAG possesses the ability to significantly improve key metrics for generative AI, such as the accuracy and relevance of responses. This is because generative AI actively utilizes external information, not only possessing extensive knowledge but also developing the ability to select and tailor the most appropriate responses to specific queries.

Thus, RAG provides innovative technical elements and functionalities for generative AI and LLMs, enabling more advanced natural language processing capabilities and flexible response generation tailored to individual needs. This allows engineers to develop more sophisticated systems while collaborating with existing APIs such as ChatGPT and Azure OpenAI Service.

Implementation and Operation of RAG Technology

RAG in Major Cloud Services

Amazon, Microsoft, and Oracle offer various services and tools to make the use of RAG (Retrieval-Augmented Generation) technology more accessible. These services aim to extend the capabilities of generative AI and allow engineers to customize it for specific applications and business needs.

Amazon Web Services (AWS) supports the implementation of RAG through an enterprise search service called Amazon Kendra. Amazon Kendra utilizes natural language processing (NLP) to extract meaningful information from unstructured text and incorporate it into the response generation process of a Large Language Model (LLM). This service enables direct integration with the knowledge bases and document repositories owned by businesses, allowing the search results to be used as inputs for generative AI.

Microsoft Azure provides a search service called Azure AI Search. This service supports vector and semantic searches, enabling engineers to index their company’s content in a searchable format and use it as part of the RAG pattern. Azure AI Search offers a valuable tool for integrating enterprise content into the generative AI response generation process, helping to produce more relevant answers.

Oracle supports RAG through the OCI Generative AI service running on Oracle Cloud Infrastructure (OCI). This service allows for the creation of customizable generative AI models and the utilization of company-specific datasets and knowledge bases. Engineers can use this service to develop generative AI applications tailored to business needs and incorporate specific information from within the organization into the response generation process.

From a technical perspective, these services provide a robust foundation for engineers to flexibly implement the RAG mechanism and optimize generative AI for specific purposes.
