DP-SGD faces fundamental privacy-utility trade-off limitations

A new research paper published on arXiv details fundamental limitations in Differentially Private Stochastic Gradient Descent (DP-SGD), a common method for private model training. The study, analyzing DP-SGD under the $f$-differential privacy framework, demonstrates that achieving both strong privacy and high utility simultaneously is challenging. The findings indicate that enforcing robust privacy necessitates a significant increase in noise, which in turn degrades model accuracy, presenting a bottleneck for DP-SGD under standard adversarial assumptions.

    Fundamental Limitations of Favorable Privacy-Utility Guarantees for DP-SGD

    arXiv:2601.10237v3 Announce Type: replace Abstract: Differentially Private Stochastic Gradient Descent (DP-SGD) is the dominant paradigm for private training, but its fundamental limitations under worst-case adversarial privacy definitions remain poorly understood. We analyze DP-…
