Researchers have introduced a new algorithm called Iterative Hessian Mixing (IHM) for differentially private ordinary least squares (DP-OLS). This method builds upon existing Gaussian sketching techniques and offers improved accuracy guarantees compared to prior approaches like Adaptive Sufficient Statistics Perturbation (AdaSSP). IHM demonstrates superior performance in empirical evaluations across various datasets, outperforming existing baselines. AI
