Introduction

This is the implementation of our paper Eliminating Domain Bias for Federated Learning in Representation Space (accepted by NeurIPS 2023). It can improve bi-directional knowledge transfer between the server and clients. We show the code of the representative FedAvg+DBE (FedDBE).

Takeaway: By eliminating domain bias in the feature extractor, we address catastrophic forgetting during local training, enhancing the generalization ability. Consequently, the global module can swiftly adapt to a new client.

Datasets and Environments

Due to the file size limitation, we only upload the fmnist dataset with the default practical setting ($\beta=0.1$). Please refer to our project PFLlib for other datasets and environments settings.

System

main.py: configurations of FedDBE.
run_me.sh: command lines to start FedDBE.
env_linux.yaml: python environment to run FedDBE on Linux.
./flcore:
- ./clients/clientDBE.py: the code on the client.
- ./servers/serverDBE.py: the code on the server.
- ./trainmodel/models.py: the code for models.
./utils:
- data_utils.py: the code to read the dataset.

Training and Evaluation

All codes corresponding to FedDBE are stored in ./system. Just run the following commands.

cd ./system
sh run_me.sh
