B Ghazi, P Kamath, R Kumar… - The Thirty Seventh …, 2024 - proceedings.mlr.press
We study the differentially private (DP) empirical risk minimization (ERM) problem under
the\emph {semi-sensitive DP} setting where only some features are sensitive. This …

Enhancing Learning with Label Differential Privacy by Vector Approximation

P Zhao, R Fan, H Wu, Q Li, J Wu, Z Liu - arXiv preprint arXiv:2405.15150, 2024 - arxiv.org
Label differential privacy (DP) is a framework that protects the privacy of labels in training
datasets, while the feature vectors are public. Existing approaches protect the privacy of …

Locally Private Estimation with Public Features

Y Ma, K Jia, H Yang - arXiv preprint arXiv:2405.13481, 2024 - arxiv.org
We initiate the study of locally differentially private (LDP) learning with public features. We
define semi-feature LDP, where some features are publicly available while the remaining …
