RAG Blends Retrieval and Generation for Grounded Answers
📊 Explaining RAG (Retrieval-Augmented Generation) RAG is a powerful technique that combines retrieval with generation to make LLMs more accurate and reliable. It works by first retrieving relevant, up-to-date information from external knowledge bases (documents, databases, wikis), then feeding that context into the LLM before generating the final answer. Core Process: 🔎Retrieve relevant data → 📝Augment the prompt → ✨Generate grounded response.
ETL: The Backbone of Modern Data Workflows
📊 The ETL Data Pipeline From raw sources (databases, APIs, files) → clean & transform (cleaning, joining, aggregating) → load into warehouse/analytics for BI, reports & ML. E → T → L: the backbone of modern data workflows.🚀
