Hello, I would like to ask how the privacy budget in the paper is calculated? The privacy budget
here is 4, is the total privacy budget after T rounds is 4, or is the privacy budget for each round is 4?

Thanks for focusing on our DP-FedSAM paper. We calculate the accumulative privacy budget along with training as follows in our CVPR paper.

And this value is accumulated privacy budget after some communication rounds.

My current code has a very large privacy budget accumulated after multiple rounds of communication. Can you provide some code related to calculating privacy budgets? This would greatly help me in gaining a better understanding of the concept and applying it to my learning.Thank you very much!
