The Normal Distributions Indistinguishability Spectrum and its Application to Privacy-Preserving Machine Learning

no code implementations3 Sep 2023 Yun Lu, Malik Magdon-Ismail, Yu Wei, Vassilis Zikas

We apply the NDIS theorem to derive DP mechanisms for queries with normally-distributed outputs -- i. e., Gaussian Random Projections (RP) -- and for more general queries -- i. e., Ordinary Least Squares (OLS).

PD-ML-Lite: Private Distributed Machine Learning from Lighweight Cryptography

no code implementations23 Jan 2019 Maksim Tsikhanovich, Malik Magdon-Ismail, Muhammad Ishaq, Vassilis Zikas

We apply our methodology to two major ML algorithms, namely non-negative matrix factorization (NMF) and singular value decomposition (SVD).
