Privacy Amplification for the Gaussian Mechanism via Bounded Support

no code implementations7 Mar 2024 Shengyuan Hu, Saeed Mahloujifar, Virginia Smith, Kamalika Chaudhuri, Chuan Guo

Data-dependent privacy accounting frameworks such as per-instance differential privacy (pDP) and Fisher information loss (FIL) confer fine-grained privacy guarantees for individuals in a fixed training dataset.

Attacking LLM Watermarks by Exploiting Their Strengths

1 code implementation25 Feb 2024 Qi Pang, Shengyuan Hu, Wenting Zheng, Virginia Smith

Advances in generative models have made it possible for AI-generated text, code, and images to mirror human-generated content in many applications.

Federated Learning as a Network Effects Game

no code implementations16 Feb 2023 Shengyuan Hu, Dung Daniel Ngo, Shuran Zheng, Virginia Smith, Zhiwei Steven Wu

Federated Learning (FL) aims to foster collaboration among a population of clients to improve the accuracy of machine learning without directly sharing local data.

On Privacy and Personalization in Cross-Silo Federated Learning

1 code implementation16 Jun 2022 Ziyu Liu, Shengyuan Hu, Zhiwei Steven Wu, Virginia Smith

While the application of differential privacy (DP) has been well-studied in cross-device federated learning (FL), there is a lack of work considering DP and its implications for cross-silo FL, a setting characterized by a limited number of clients each containing many data subjects.

A New Defense Against Adversarial Images: Turning a Weakness into a Strength

1 code implementation NeurIPS 2019 Tao Yu, Shengyuan Hu, Chuan Guo, Wei-Lun Chao, Kilian Q. Weinberger

Natural images are virtually surrounded by low-density misclassified regions that can be efficiently discovered by gradient-guided search --- enabling the generation of adversarial images.
