Thermodynamic Signatures of Reasoning: Free-Energy and Spectral-Form-Factor Diagnostics for Hallucination Detection in Large Language Models
Researchers introduced Free-Energy Signatures (Fes), a spectral descriptor for hallucination detection in large language models that treats attention Laplacians as Hamiltonians to extract thermodynami…
