Problem

How do you handle hallucinations in LLM-based applications?

Explain a practical machine learning approach for detecting and reducing unsupported LLM claims. Cover data preparation, model or architecture choice, grounding, confidence thresholds, evaluation, monitoring, and fallback behavior. Assume the application has user queries, retrieved context, generated answers, and human labels indicating whether each answer is supported by the available evidence.
