A Sharper Picture of Generalization in Transformers

Researchers present a new theoretical framework for understanding how transformers generalize on boolean functions using PAC-Bayes theory and Fourier spectral analysis. The work provides non-vacuous generalization bounds for transformers and offers formal explanations for why chain-of-thought reasoning improves performance on complex tasks.

FragileFlow: Spectral Control of Correct-but-Fragile Predictions for Foundation Model Robustness

FragileFlow introduces a theoretical framework and practical regularizer to detect and mitigate a hidden failure mode in large language models and vision-language models where predictions remain technically correct but confidence margins narrow dangerously. The research provides the first PAC-Bayes bounds for margin-aware error flow, addressing robustness gaps that standard accuracy metrics overlook.
