Course Outline

Foundations of Retrieval-Augmented Generation (RAG)

  • Defining RAG and its significance for enterprise AI initiatives
  • Key components: the retriever, generator, and document storage mechanisms
  • Contrasting RAG with standalone LLMs and pure vector search approaches

Establishing the RAG Pipeline

  • Setup and configuration of frameworks such as Haystack
  • Processes for ingesting and preprocessing documentation
  • Integration of retrievers with vector databases like FAISS or Pinecone

Optimizing the Retriever Component

  • Training dense retrieval models using specialized domain data
  • Leveraging sentence transformers and contrastive learning methods
  • Assessing retrieval precision through top-k accuracy metrics

Enhancing the Generator Component

  • Choosing appropriate base models, including BART, T5, or FLAN-T5
  • Differentiating between instruction tuning and supervised fine-tuning
  • Utilizing LoRA and PEFT methods for efficient model updates

Performance Evaluation and Optimization

  • Applying metrics like BLEU, EM, and F1 to gauge RAG success
  • Managing latency, retrieval quality, and minimizing hallucinations
  • Implementing experiment tracking for continuous iterative improvement

Deployment and Enterprise Integration

  • Implementing RAG within internal search engines and conversational AI
  • Addressing security protocols, data access controls, and governance
  • Connecting with external APIs, dashboards, and knowledge portals

Industry Case Studies and Best Practices

  • Real-world applications in finance, healthcare, and legal sectors
  • Strategies for managing domain drift and updating knowledge bases
