Digest

This episode of the Beginners Guide to AI explores Retrieval Augmented Generation (RAG), a groundbreaking technique in natural language processing. RAG combines the power of retrieval-based models and generative models to create more accurate and contextually relevant responses. Generative models, like GPT-4, are trained on vast amounts of text data and learn patterns and knowledge. However, they are limited to the information available at their last training update. Retrieval-based models, on the other hand, actively search for relevant information from external databases or documents, providing access to the latest data. RAG merges these two approaches, first retrieving relevant information from external sources and then using this data to enhance the generative model's response. This hybrid approach ensures that AI responses are informed by both training data and real-time information, making them more accurate and relevant. The episode uses a simple example of baking a cake to illustrate how RAG can provide more helpful advice by incorporating the latest culinary blogs and articles. A hypothetical case study in the medical field further highlights RAG's potential, showcasing how it can assist doctors and medical staff with up-to-date treatment protocols, research findings, and drug information. RAG also reduces the occurrence of AI hallucinations by grounding the generative model with real, retrieved data. The episode concludes by emphasizing the importance of continuous learning and encourages listeners to explore RAG further.
