arXiv:2607.01492v1 Announce Type: new Abstract: Recent work has established a fundamental trilemma between Byzantine robustness, local differential privacy (LDP), and optimization error in distributed learning. We show that this trilemma does not universally extend to generalization error, but instead depends critically on the privacy regime. Specifically, in the high-noise regime (strong privacy), we prove that increasing privacy reduces the generalization error, i.e., there is no tension between robustness and privacy. In the low-noise regime (weaker privacy), however, the tension between ro
This research addresses fundamental trade-offs in distributed learning, a critical area given the increasing demand for secure and private AI systems.
Understanding the complex relationship between privacy, robustness, and generalization is crucial for designing trustworthy and effective AI models, impacting deployment across sensitive sectors.
The findings challenge previous assumptions about the universal trilemma, indicating that privacy can sometimes improve generalization rather than always degrading it, depending on the noise regime.
