Game-Changing Techniques to Enhance Q&A Systems
- Fine-Tuning: This technique involves customizing the embedding model used in RAG’s retrieval step, the generative model used in RAG’s generation step, or both, in order to make such models grasp the unique nuances of specific domains. Fine-tuning embedding models enables them to retrieve more relevant information by understanding domain-specific terminology and context. Likewise, fine-tuning generative models enhances their ability to produce accurate and contextually appropriate answers.
- Iterative Reasoning: This technique leverages the Observe-Orient-Decide-Act (OODA) paradigm to refine the AI's answers through multiple steps, continuously improving accuracy and relevance. The loop involves: (i) Observing relevant information from available resources; (ii) Orienting whether such collection of information is sufficient to solve the problem at hand; (iii) Deciding whether to solve the problem directly in one go, or to decompose it further into more manageable sub-problems; and (iv) Act to execute such decision, and update the status of the problem-solving process. This iterative process enables the AI to consider multiple perspectives, gather additional information, and adjust its answers, much like human problem-solving.
"Our research provides best practices for advancing domain-specific Q&A using retrieval-augmented generation, accelerating AI systems that understand specialized knowledge." – Zooey Nguyen, AI engineer & author from Aitomatic
