Learning Differentially Private Probabilistic Models for Privacy-Preserving Image Generation

no code implementations18 May 2023 Bochao Liu, Shiming Ge, Pengju Wang, Liansheng Zhuang, Tongliang Liu

In particular, we first train a model to fit the distribution of the training data and make it satisfy differential privacy by performing a randomized response mechanism during training process.
