PLAN: Variance-Aware Private Mean Estimation

1 code implementation14 Jun 2023 Martin Aumüller, Christian Janos Lebeda, Boel Nelson, Rasmus Pagh

Under a concentration assumption on $\mathcal{D}$, we show how to exploit skew in the vector $\boldsymbol{\sigma}$, obtaining a (zero-concentrated) differentially private mean estimate with $\ell_2$ error proportional to $\|\boldsymbol{\sigma}\|_1$.

To fill the gap in the literature, we propose a novel application of factor experiments to create data aware error predictions.
