Understanding Generative AI and Retrieval Augmented Generation (RAG)

What Does Hallucination Mean in AI?

Generative AI, or Gen AI, is a cutting-edge technology that generates original content, including text, art, and music, by leveraging vast amounts of data available on the internet. While this technology has the potential to revolutionize content creation, it is not infallible. One of the notable challenges with Gen AI is its tendency to “hallucinate,” or produce factually incorrect or unverifiable answers. Retrieval Augmented Generation (RAG) is an approach to mitigate hallucinations.

What Does Hallucination Mean in AI?

In human terms, hallucination involves seeing or hearing things that aren’t present. Similarly, in AI, hallucination occurs when a tool like ChatGPT or CoPilot generates answers that are not grounded in fact. This can lead to misinformation if not adequately controlled.

Retrieval Augmented Generation: A Solution to Reduce AI Hallucinations

Retrieval Augmented Generation (RAG) is a sophisticated approach developed to mitigate the issue of AI hallucinations. Unlike standard AI queries, RAG enhances the reliability of AI responses through a two-step process:

  • Information Retrieval: Initially, RAG consults a custom database to fetch relevant documents or data pertaining to the query.
  • Response Generation: Leveraging this retrieved information, a large language model then generates a more accurate and relevant response.

This method effectively anchors AI responses to real-world data, enhancing the credibility and reliability of the output.

How Does Retrieval Augmented Generation Work?

As explained by Pablo Arredondo, vice president of CoCounsel at Thomson Reuters, RAG operates by pulling in real documents based on the query’s topic. This direct linkage to factual documents helps ground the AI’s responses, making them less prone to errors and fabrications. However, it’s important to note that while RAG significantly reduces the occurrence of hallucinations, it is not entirely foolproof.

Factors Influencing the Effectiveness of Retrieval Augmented Generation

Several factors contribute to the effectiveness of the RAG approach in reducing AI hallucinations:

  • Quality of Source Content: The accuracy of the RAG’s outputs heavily depends on the reliability of the data it retrieves.
  • Efficiency of Search Algorithms: The search mechanism must be capable of retrieving the most relevant and high-quality content related to the query.
  • Fidelity of the Data: The final response should be not only relevant but also factually correct, based on the sourced data.
