Differentially Private Latent Diffusion Models

no code implementations25 May 2023 Saiyue Lyu, Michael F. Liu, Margarita Vinaroz, Mijung Park

In this paper, we further improve the current state of DMs with DP by adopting the Latent Diffusion Models (LDMs).

Differentially Private Kernel Inducing Points using features from ScatterNets (DP-KIP-ScatterNet) for Privacy Preserving Data Distillation

2 code implementations31 Jan 2023 Margarita Vinaroz, Mi Jung Park

Data distillation aims to generate a small data set that closely mimics the performance of a given learning algorithm on the original data set.

Differentially private stochastic expectation propagation (DP-SEP)

no code implementations25 Nov 2021 Margarita Vinaroz, Mijung Park

We provide a theoretical analysis of the privacy-accuracy trade-off in the posterior estimates under our method, called differentially private stochastic expectation propagation (DP-SEP).

Hermite Polynomial Features for Private Data Generation

1 code implementation9 Jun 2021 Margarita Vinaroz, Mohammad-Amin Charusaie, Frederik Harder, Kamil Adamczewski, Mijung Park

Hence, a relatively low order of Hermite polynomial features can more accurately approximate the mean embedding of the data distribution compared to a significantly higher number of random features.

ABCDP: Approximate Bayesian Computation with Differential Privacy

no code implementations11 Oct 2019 Mijung Park, Margarita Vinaroz, Wittawat Jitkrittum

SVT incurs the privacy cost only when a condition (whether a quantity of interest is above/below a threshold) is met.
