Question about FedAvg code

[Grassyue]

Thanks for sharing your code, it is an amazing work！
But I have a question on the implementation of FedAvg：

MOON/main.py

Line 587 in dbf6344

global_w[key] += net_para[key] * fed_avg_freqs[net_id]

why here aggregation without a "mean" operation ?

Hi @Grassyue and @qiaojy19 ,

Yes, fed_avg_freqs[net_id] is the weight of each model. The weight is related to the data size of each party. The weights are not equal to 1/n if the data size of each party is different.

Thank you for your reply! 😃 @qiaojy19 @QinbinLi
