  1. User-level Differentially Private Stochastic Convex Optimization: Efficient Algorithms with Optimal Rates

    2023 · arXiv (Cornell University)

    We study differentially private stochastic convex optimization (DP-SCO) under user-level privacy, where each user may hold multiple data items. Existing work for user-level DP-SCO either requires super-polynomial runtime [Ghazi et al. (2023)] or requires the …
