From Dispersion to Attraction: Spectral Dynamics of Hallucination Across Whisper Model Scales

Researchers propose the Spectral Sensitivity Theorem to explain hallucinations in large ASR models like Whisper, identifying a phase transition between dispersive and attractor regimes. Analysis of model eigenspectra reveals that intermediate models experience structural breakdown while large models compress information, decoupling from acoustic evidence and increasing hallucination risk.

Rethinking Entropy Minimization in Test-Time Adaptation for Autoregressive Models

Researchers present a unified mathematical framework for Test-Time Adaptation (TTA) in autoregressive generative models, decomposing entropy minimization into token-level policy gradient and entropy losses. Validated on Whisper ASR across 20+ domains, the approach demonstrates consistent performance improvements and reconciles previously disparate adaptation methods under a single theoretical foundation.
