PLD accountants precisely evaluate differential privacy guarantees by computing the full distribution of the privacy loss random variable, directly performing numerical convolution on the likelihood ratio of the privacy loss distribution, thereby giving a tighter lower bound on ε under the same privacy budget.

UnverifiedDifferential privacy is a rigorous mathematical definition of privacy: a randomized algorithm satisfies (ε, δ)-DP if the difference in output distributions on any adjacent datasets is constrained by ε and δ; the smaller ε is, the stronger the privacy protection, but usually at the cost of degraded model utility.78% similarUnverifiedRènyi differential privacy (RDP) is defined based on Rènyi divergence, provides tighter composition of privacy loss than pure differential privacy, and is widely used in machine learning and statistical analysis.72% similarUnverifiedDP-SGD protects privacy by adding Gaussian noise to gradients, and privacy accounting tools (such as Rényi DP or zCDP) can precisely compute the cumulative privacy loss.68% similarVerifiedDifferential Privacy was formally defined by Cynthia Dwork in 2006, with its core guarantee being that the output of an algorithm will not change significantly due to the addition or removal of any single record in the dataset.67% similarUnverifiedDifferentially private stochastic gradient descent (DP-SGD) has become the de facto standard for training privacy-sensitive models.67% similar
