FedDisco: Federated Learning with Discrepancy-Aware Collaboration, ICML2023

This repo is the pytorch implementation of ICML2023 paper "FedDisco: Federated Learning with Discrepancy-Aware Collaboration". PMLR Link

Prerequisites

• Python 3.9

• CUDA 11.3

• Pytorch 1.10.2

• Torchvision 0.11.3

  Please refer to requirements.txt for more details. This code should work on most builds.

Preparing dataset and model

The argument --datadir in args.py specifies the location of dataset.

The argument --model has three valid values: resnet18_gn , simple-cnn and simple-cnn-mnist . The first one is ResNet for HAM10000 dataset while other two are simple CNN networks for small-scale dataset with RGB or grayscale images.

Federated training

We provide several shell scripts for training in several settings. The format is

sh disco_sh/$DATASET_$PARTITION.sh

For example, to train on Fashion-MNIST dataset with NIID-1 partition, run

sh disco_sh/fmnist_1.sh

To train on CIFAR-10 dataset with NIID-2 partition, run

sh disco_sh/cifar10_2.sh

Note that --alg specifies an algorithm.

Tuning parameters of Disco

To run the experiments of baselines, please keep --disco=0. To integrate with our FedDisco, let --disco=1 and change the value of --disco_a and --disco_b.
