Differentially Private Statistical Inference through $β$-Divergence One Posterior Sampling

no code implementations11 Jul 2023 Jack Jewson, Sahra Ghalebikesabi, Chris Holmes

To ameliorate this, we propose $\beta$D-Bayes, a posterior sampling scheme from a generalised posterior targeting the minimisation of the $\beta$-divergence between the model and the data generating process.

Mitigating Statistical Bias within Differentially Private Synthetic Data

no code implementations24 Aug 2021 Sahra Ghalebikesabi, Harrison Wilde, Jack Jewson, Arnaud Doucet, Sebastian Vollmer, Chris Holmes

Increasing interest in privacy-preserving machine learning has led to new and evolved approaches for generating private synthetic data from undisclosed real data.

Privacy Preserving

Foundations of Bayesian Learning from Synthetic Data

no code implementations16 Nov 2020 Harrison Wilde, Jack Jewson, Sebastian Vollmer, Chris Holmes

There is significant growth and interest in the use of synthetic data as an enabler for machine learning in environments where the release of real data is restricted due to privacy or availability constraints.

Doubly Robust Bayesian Inference for Non-Stationary Streaming Data with $β$-Divergences

1 code implementation NeurIPS 2018 Jeremias Knoblauch, Jack Jewson, Theodoros Damoulas

The resulting inference procedure is doubly robust for both the parameter and the changepoint (CP) posterior, with linear time and constant space complexity.
