Course Outline

Foundations of Retrieval-Augmented Generation (RAG)

  • The definition of RAG and its strategic value in enterprise AI.
  • Core constituents: retriever, generator, and document store.
  • Differentiating RAG from standalone LLMs and pure vector search solutions.

Establishing a RAG Pipeline

  • Configuration of Haystack or comparable frameworks.
  • Processes for document ingestion and data preprocessing.
  • Linking retrievers with vector databases such as FAISS or Pinecone.

Optimizing the Retriever

  • Training dense retrievers with specialized, domain-specific data.
  • Applying sentence transformers and contrastive learning techniques.
  • Measuring retriever effectiveness through top-k accuracy metrics.

Enhancing the Generator

  • Choosing appropriate base models like BART, T5, or FLAN-T5.
  • Distinguishing between instruction tuning and supervised fine-tuning.
  • Utilizing LoRA and PEFT methods for resource-efficient updates.

Assessment and Optimization

  • Key performance indicators including BLEU, EM, and F1 scores.
  • Focusing on latency, retrieval precision, and minimizing hallucinations.
  • Tracking experiments for continuous, iterative improvement.

Deployment and Practical Integration

  • Rolling out RAG within internal search engines and chatbot interfaces.
  • Navigating security, data access controls, and governance protocols.
  • Connecting RAG systems with APIs, dashboards, or knowledge portals.

Case Studies and Industry Best Practices

  • Real-world applications in finance, healthcare, and legal sectors.
  • Strategies for managing domain drift and knowledge base refreshes.
  • Emerging trends and future trajectories in retrieval-augmented LLM systems.

Conclusion and Path Forward
