PATE-GAN: Moments Accountant #596

Open ganevgv opened 5 months ago

ganevgv commented 5 months ago

Upon inspecting PATE-GAN, I believe there is a forgotten log operation in the moments accountant on L44 (corresponding to the second term in Algorithm 1 on page 7 from the paper). This makes the accountant overestimate the budget under certain conditions.
