About this course

Build a retrieval-based assistant over permitted learning material. Focus on finding useful evidence, citing actual sources and recognizing when the material does not support an answer.

What you will be able to do

  • Prepare permitted source documents and retrieve relevant passages.
  • Return citations tied to the passages actually used.
  • Evaluate supported answers, missing evidence and instruction-like text inside sources.
