When RAG gets It wrong: Detecting hallucinations and controlling risk
RAG systems can retrieve relevant information and still generate incorrect or unsupported answers. As AI applications move into production, engineers need reliable ways to detect these failures and determine when a model should respond, escalate, or abstain. Drawing on research into educational recommendation systems and risk-controlled Agentic RAG, this session explores how retrieval uncertainty, generation uncertainty, and statistical calibration can improve the reliability of AI-generated responses. Key takeaways: → Identifying hallucinations and measuring uncertainty across retrieval and generation → Designing risk-based controls to determine when models should answer, escalate, or abstain → Applying these techniques to educational recommendations and other evidence-grounded AI applications
