Learn to build a foundational RAG-based document QA system and understand its architecture and key lessons learned

advanced Published 30 Apr 2026
Action Steps
  1. Design a RAG-based architecture for document QA using retrieval and generation components
  2. Implement a retrieval module to fetch relevant documents based on user queries
  3. Develop a generation module to produce answers based on the retrieved documents
  4. Train and fine-tune the model using a large dataset of documents and user queries
  5. Evaluate the performance of the RAG-based system using metrics such as accuracy and F1-score
