Episode 24 — Retrieval-Augmented Generation (RAG): Using Your Own Data
This episode introduces retrieval-augmented generation, or RAG, a method of enhancing large language models by grounding them in external data sources. Instead of relying solely on a model’s internal training, RAG retrieves relevant documents or records and provides them as context during generation. This improves factual accuracy, reduces hallucinations, and enables customization with proprietary information. For certification exams, learners should recognize RAG as a practical solution for applying AI to domain-specific contexts, such as legal, medical, or organizational knowledge bases.
Practical examples clarify its value. A customer support assistant can retrieve current policy documents to provide accurate answers, while a compliance tool can reference the latest regulations. Technical considerations include building embeddings, indexing documents in a vector database, and managing latency during retrieval. Exam questions may frame scenarios where a plain language model fails, asking which enhancement makes it reliable, with RAG as the correct answer. Best practices emphasize keeping knowledge bases updated, validating retrieval quality, and ensuring security when exposing proprietary data. By mastering the concept of RAG, learners position themselves to answer exam items and deploy AI responsibly in professional environments.
