The passage around this formula
The final mechanism worth separating out is synthetic data generation aimed specifically at privacy rather than capability — producing a dataset that preserves the statistical properties of a sensitive real dataset (medical records, private communications) without preserving any individual record well enough to be re-identified. The standard mechanical tool here is differential privacy, formalized by Abadi and colleagues’ DP-SGD algorithm, which modifies ordinary stochastic gradient descent by clipping each individual training example’s gradient contribution to a bounded norm and then adding calibrated random noise before the aggregated update is applied [ 9 ] . The guarantee this produces…

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
