🧠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.

🧠Researchers present a parameter-free wrapper method (WNE) that enforces Normalization Equivariance—robustness to brightness and contrast shifts—around any neural network backbone without architectural constraints. The approach characterizes NE as a normalize-process-denormalize factorization, enabling compatibility with modern components like transformers and attention mechanisms while avoiding the 1.6x computational overhead of existing methods.

🧠Researchers propose a conformal prediction framework for large language models that uses internal neural representations rather than surface-level outputs to assess reliability and uncertainty. The Layer-Wise Information scoring method improves prediction validity under distribution shift while maintaining competitive performance, addressing a critical challenge in deploying LLMs where traditional uncertainty signals become unreliable.

🧠Researchers demonstrate that large language models can extract predictive features from financial news with valid intermediate signals (Information Coefficient >0.15), yet these features fail to improve reinforcement learning trading agents during macroeconomic shocks. The findings reveal a critical gap between feature-level validity and downstream policy robustness, suggesting that valid signals alone cannot guarantee trading performance under distribution shifts.
