Table 1:

Experimental results for NoisySGD and their privacy analyses on MNIST. The accuracy is averaged over 10 independent runs. The hyperparameters in the first three rows are the same as in [2]. The μ in the 6th row is calculated using (5), which carries over to the 7th row via (6) with δ = 10⁻⁵. The number of epochs is equal to T × mini-batch size/n = pT.
