What is the most effective way to mitigate hallucinations in Generative AI systems?

Using retrieval-augmented generation is an effective way to mitigate hallucinations in generative AI systems because it combines the generative capabilities of AI with an external information retrieval process. By integrating a retrieval mechanism, the model can pull real-time, factual information from a database or knowledge source when generating responses. This approach helps ground the outputs in reality, significantly reducing the chance of producing false or misleading information that characterizes hallucinations.

In retrieval-augmented generation, the generative model first identifies what information is needed based on the input query and then retrieves relevant data from trustworthy sources. This ensures that the generated content aligns more closely with verified information, thus increasing accuracy and reliability.

The other strategies listed, while potentially beneficial in various contexts, do not directly address hallucinations as effectively. For instance, enhancing model complexity could lead to overfitting on training data and increase the frequency of hallucinations, rather than mitigate them. Limiting training data sources may restrict the model’s knowledge and general performance, and might not prevent hallucinations if the remaining data is still misleading. Employing human oversight is valuable but often requires additional resources and may not be scalable for all applications. Therefore, retrieval-augmented generation stands out as the most effective and practical approach for
