  bibo_abstract:
  - We study differentially private model training with stochastic gradient descent
    under learning rate scheduling and correlated noise. Although correlated noise,
    in particular via matrix factorizations, has been shown to improve accuracy, prior
    theoretical work focused primarily on the prefix-sum workload. That workload assumes
    a constant learning rate, whereas in practice learning rate schedules are widely
    used to accelerate training and improve convergence. We close this gap by deriving
    general upper and lower bounds for a broad class of learning rate schedules in
    both single- and multi-epoch settings. Building on these results, we propose a
    learning-rate-aware factorization that achieves improvements over prefix-sum factorizations
    under both MaxSE and MeanSE error metrics. Our theoretical analysis yields memory-efficient
    constructions suitable for practical deployment, and experiments on CIFAR-10 and
    IMDB datasets confirm that schedule-aware factorizations improve accuracy in private
    training.@eng
