Implementing the algorithm from our paper: "A Reputation Mechanism Is All You Need: Collaborative Fairness and Adversarial Robustness in Federated Learning". Accepted as Oral presentation (13.2%) at International Workshop on Federated Learning for User Privacy and Data Confidentiality in Conjunction with ICML 2021 (FL-ICML'21), view the workshop page.

📋 In this work, we propose a Robust Fair Federated Learning (RFFL) framework to simultaneously achieve adversarial robustness and collaborative fairness in Federated learning by using a reputation mechanism.

To install requirements:

conda env create -f environment.yml

📋 We recommend managing your environment using Anaconda, both for the versions of the packages used here and for easy management.

📋 Our code automatically detects GPU(s) through NVIDIA driver, and if not available it will use CPU instead.

To run the code in the paper, run this command:

python RFFL_run.py -d mnist -N 10 -A 2 -cuda

The above command means to run MNIST dataset, with 10 honest participants and 2 adversaries.

📋 Note there are several command-line arguments which can be found in RFFL_run.py.

📋 Running RFFL_run.py starts the experiments specified by the arguments and it creates and writes to corresponding directories.
