PyTorch implementation of Layer-wised Model Aggregation for Personalized Federated Learning

pFedLA(HeurpFedLA), FedAvg, FedBN

NOTE: This's not the official Repo.

So maybe some hyperparameters not mentioned in paper aren't optimal.

All datasets mentioned in paper are supported(CIFAR10, ...).

If you find sth wrong about the code, feel free to open an issue or pr.

Run

Generating clients dataset

Segmenting by Dirichlet($\alpha$) and Randomly assigning classes are supported.

E.g.

python ./src/data/run.py --dataset cifar10 --classes 4 --client_num_in_total 10

Check ./src/data/run.py for more Info of all arguments.

Training

Scripts for running pFedLA with fixed args are in ./scripts

cd ./scripts;
chmod +x ./*;
sh ${script}

Also, you can directly run python ./src/server/${algo}.py with your custom arguments after generate clients dataset.
