Retrieval-Augmented Generation - (RAG)
RAG (Retrieval-Augmented Generation) is an AI technique that combines information retrieval with text generation. In this approach, a model retrieves relevant documents or information from a knowledge base before generating a response, ensuring that the output is accurate and grounded in factual data rather than relying solely on the model's internal knowledge.
Key Characteristics
- Retrieval Component: Retrieves relevant information from external sources
- Generation Component: Generates responses based on retrieved information
- Factual Grounding: Ensures responses are based on factual data
- Dynamic Knowledge: Can access up-to-date information
Advantages
- Accuracy: Improves accuracy by grounding responses in factual data
- Up-to-Date Information: Can access recent information not in training data
- Reduced Hallucination: Reduces hallucination by relying on source documents
- Explainability: Provides sources for generated responses
Disadvantages
- Complexity: More complex architecture than standalone models
- Latency: Additional retrieval step increases response time
- Resource Requirements: Requires maintaining knowledge bases
- Retrieval Quality: Performance depends on quality of retrieval
Best Practices
- Maintain high-quality, well-structured knowledge bases
- Optimize retrieval algorithms for speed and accuracy
- Implement proper source attribution
- Monitor retrieval and generation quality separately
Use Cases
- Question-answering systems
- Document analysis and summarization
- Enterprise knowledge management
- Research assistance tools
