PGGD

[sotirisnik]

Could you clarify how do you calculate the avg_gradient that is given as input in the pggd file? I could not find the script that imports this file.

Thank you

Thanks for the question. FedProx does not use this optimizer. This is instead used in our FedDANE paper, where the updates correspond to Line 7 in Algorithm 2 in our paper. There is some redundancy when we clean up the code and release it.
