Collaborative Learning From Distributed Data With Differentially Private Synthetic Twin Data

1 code implementation9 Aug 2023 Lukas Prediger, Joonas Jälkö, Antti Honkela, Samuel Kaski

Consider a setting where multiple parties holding sensitive data aim to collaboratively learn population level statistics, but pooling the sensitive data sets is not possible.

DPVIm: Differentially Private Variational Inference Improved

no code implementations28 Oct 2022 Joonas Jälkö, Lukas Prediger, Antti Honkela, Samuel Kaski

Using this as prior knowledge we establish a link between the gradients of the variational parameters, and propose an efficient while simple fix for the problem to obtain a less noisy gradient estimator, which we call $\textit{aligned}$ gradients.

D3p -- A Python Package for Differentially-Private Probabilistic Programming

1 code implementation22 Mar 2021 Lukas Prediger, Niki Loppi, Samuel Kaski, Antti Honkela

We present d3p, a software package designed to help fielding runtime efficient widely-applicable Bayesian inference under differential privacy guarantees.

Tight Differential Privacy for Discrete-Valued Mechanisms and for the Subsampled Gaussian Mechanism Using FFT

1 code implementation12 Jun 2020 Antti Koskela, Joonas Jälkö, Lukas Prediger, Antti Honkela

We carry out an error analysis of the method in terms of moment bounds of the privacy loss distribution which leads to rigorous lower and upper bounds for the true $(\varepsilon,\delta)$-values.
