Summary Statistic Privacy in Data Sharing

1 code implementation3 Mar 2023 Zinan Lin, Shuaiqi Wang, Vyas Sekar, Giulia Fanti

We study a setting where a data holder wishes to share data with a receiver, without revealing certain summary statistics of the data distribution (e. g., mean, standard deviation).

On the Privacy Properties of GAN-generated Samples

no code implementations3 Jun 2022 Zinan Lin, Vyas Sekar, Giulia Fanti

By drawing connections to the generalization properties of GANs, we prove that under some assumptions, GAN-generated samples inherently satisfy some (weak) privacy guarantees.

RareGAN: Generating Samples for Rare Classes

1 code implementation20 Mar 2022 Zinan Lin, Hao Liang, Giulia Fanti, Vyas Sekar

We study the problem of learning generative adversarial networks (GANs) for a rare class of an unlabeled dataset subject to a labeling budget.

Pareto GAN: Extending the Representational Power of GANs to Heavy-Tailed Distributions

no code implementations22 Jan 2021 Todd Huster, Jeremy E. J. Cohen, Zinan Lin, Kevin Chan, Charles Kamhoua, Nandi Leslie, Cho-Yu Jason Chiang, Vyas Sekar

A Pareto GAN leverages extreme value theory and the functional properties of neural networks to learn a distribution that matches the asymptotic behavior of the marginal distributions of the features.

Why Spectral Normalization Stabilizes GANs: Analysis and Improvements

1 code implementation NeurIPS 2021 Zinan Lin, Vyas Sekar, Giulia Fanti

Spectral normalization (SN) is a widely-used technique for improving the stability and sample quality of Generative Adversarial Networks (GANs).

Enhancing the Privacy of Federated Learning with Sketching

no code implementations5 Nov 2019 Zaoxing Liu, Tian Li, Virginia Smith, Vyas Sekar

Federated learning methods run training tasks directly on user devices and do not share the raw user data with third parties.

Using GANs for Sharing Networked Time Series Data: Challenges, Initial Promise, and Open Questions

4 code implementations30 Sep 2019 Zinan Lin, Alankar Jain, Chen Wang, Giulia Fanti, Vyas Sekar

By shedding light on the promise and challenges, we hope our work can rekindle the conversation on workflows for data sharing.

Practical Verifiable In-network Filtering for DDoS defense

1 code implementation4 Jan 2019 Deli Gong, Muoi Tran, Shweta Shinde, Hao Jin, Vyas Sekar, Prateek Saxena, Min Suk Kang

In this paper, we show the technical feasibility of verifiable in-network filtering, called VIF, that offers filtering verifiability to DDoS victims and neighbor ASes.
