We propose employing Bayesian differential privacy as the means to achieve a rigorous theoretical guarantee while providing a better privacy-utility trade-off. We demonstrate experimentally that our approach produces higher-fidelity samples compared to prior work, allowing to (1) detect more subtle data errors and biases, and (2) reduce the need for real data labelling by achieving high accuracy when training directly on artificial samples.Computer Science, Artificial IntelligenceComputer Science, Theory & MethodsComputer Sciencemachine learningsynthetic datagenerative adversarial networksprivacyGenerating Higher-Fidelity Synthetic Datasets with Privacy Guaranteestext::journal::journal article::research article
