Preprocessing Unstructured Data for LLM Applications
by DeepLearning.AI × Unstructured
Get PDFs, slides, and HTML into clean, chunked, metadata-rich form — the unglamorous 80% of RAG.
Overview
Most RAG quality problems start at ingestion. This course, built with Unstructured.io, teaches document parsing across formats — PDFs, PowerPoint, HTML, and images — plus chunking strategies, metadata extraction, and normalization. You build a pipeline that turns heterogeneous enterprise documents into consistent, searchable chunks, which is the foundation any good retrieval system depends on.
