Course Outline

Overview of Retrieval-Augmented Generation (RAG)

  • Defining RAG and its significance for enterprise AI.
  • Key components: retriever, generator, and document store.
  • Differentiating RAG from standalone LLMs and vector search.

Configuring the RAG Pipeline

  • Setting up and configuring Haystack or equivalent frameworks.
  • Handling document ingestion and data preprocessing.
  • Linking retrievers to vector databases like FAISS or Pinecone.

Refining the Retriever

  • Training dense retrievers on domain-specific datasets.
  • Leveraging sentence transformers and contrastive learning strategies.
  • Assessing retriever effectiveness using top-k accuracy metrics.

Optimizing the Generator

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

Performance Evaluation and Tuning

  • Utilizing metrics like BLEU, EM, and F1 to measure RAG output.
  • Addressing latency, retrieval precision, and hallucination mitigation.
  • Implementing experiment tracking for continuous iterative improvement.

Implementation and Enterprise Integration

  • Integrating RAG into internal search engines and chatbot interfaces.
  • Navigating security, data access, and governance protocols.
  • Connecting with APIs, dashboards, or knowledge portals.

Industry Case Studies and Best Practices

  • Real-world applications in finance, healthcare, and legal sectors.
  • Strategies for managing domain drift and maintaining knowledge bases.
  • Exploring future trends in retrieval-augmented LLM architectures.
