Webapproaches are data-driven and rely on generative methods using generative adversarial networks (GAN) [21]. GANs are deep neural networks that produce two jointly-trained networks; one generates synthetic data intended to be as similar as possible to the train-ing data, and one tries to discriminate the synthetic data from true training data. They WebFeb 18, 2024 · The synthetic dataset represents a “fake” sample derived from the original data while retaining as many statistical characteristics as possible. The essential advantage of the synthesizer approach is that the differentially private dataset can be analyzed any number of times without increasing the privacy risk.
