Entropy-based Uncertainty Detection

Definition
Detecting uncertain or unstable LLM outputs using entropy measures.
Explanation
Entropy measures the dispersion in token probability distributions. High entropy means the LLM is uncertain. Enterprises use entropy-based systems to redirect outputs to verification layers, trigger retrieval, escalate to larger models, or block unsafe responses.
Technical Architecture
Token Probabilities → Entropy Calculator → Decision Engine → (Accept / Verify / Escalate)
Core Component
Entropy meter, scoring thresholds, routing logic
Use Cases
Risk-sensitive workflows, legal QA, medical summarization
Pitfalls
Entropy does not always correlate with correctness
