Improved Bounds for Private and Robust Language Model Alignment

This paper addresses the critical problem of aligning language models while considering privacy and robustness to adversarial attacks. It provides theoretical upper bounds on the suboptimality gap in both offline and online settings, offering valuable insights into the trade-offs between privacy, robustness, and performance. The paper's contributions are significant because they challenge conventional wisdom and provide improved guarantees for existing algorithms, especially in the context of privacy and corruption. The new uniform convergence guarantees are also broadly applicable.
