Adaptive Federated Learning in Resource Constrained Edge Computing Systems

This repository is based on the source code for the paper S. Wang, T. Tuor, T. Salonidis, K. K. Leung, C. Makaya, T. He, and K. Chan, "Adaptive federated learning in resource constrained edge computing systems," IEEE Journal on Selected Areas in Communications, vol. 37, no. 6, pp. 1205 – 1221, Jun. 2019.

I used it as a starter code for a class project in UW CSE 561. The final paper for the class and corresponding 5 minute presentation are in this folder named AdaptiveFederatedLearning.pdf and Adaptive Federated Learning.pdf respectively.

Getting Started

The code runs on Python 3 with Tensorflow version 1 (>=1.13). To install the dependencies, run

pip3 install -r requirements.txt

Then, download the datasets manually and put them into the datasets folder.

• For MNIST dataset, download from http://yann.lecun.com/exdb/mnist/ and put the standalone files into datasets/mnist.
• For CIFAR-10 dataset, download the "CIFAR-10 binary version (suitable for C programs)" from https://www.cs.toronto.edu/~kriz/cifar.html, extract the standalone *.bin files and put them into datasets/cifar-10-batches-bin.

To test the code:

• Run server.py and wait until you see Waiting for incoming connections... in the console output.
• Run 5 parallel instances of client.py on the same machine as the server.
• You will see console outputs on both the server and clients indicating message exchanges. The code will run for a few minutes before finishing.
• After the server and clients finish, run plot_multi_run.py which will plot the result. This figure will look similar to the SVM(SGD) subfigures in Fig. 4 of the paper (but with higher fluctuation).

Code Structure

All configuration options are given in config.py which also explains the different setups that the code can run with.

The results are saved as CSV files in the results folder. The CSV files should be deleted before starting a new round of experiment. Otherwise, the new results will be appended to the existing file.

Currently, the supported datasets are MNIST and CIFAR-10, and the supported models are SVM and CNN. The code can be extended to support other datasets and models too.
