Personalized federated learning simulation platform with Non-IID dataset

The origin of the Non-IID phenomenon is the personalization of users, who generate the Non-IID data. With Non-IID (Not Independent and Identically Distributed) issue existing in the federated learning setting, a myriad of approaches has been proposed to crack this hard nut. In contrast, the personalized federated learning may take the advantage of the Non-IID data to learn the personalized model for each user. Thanks to @Stonesjtu, this platform can also record the GPU memory usage for the model. By using the package opacus, I introduce differential privacy into this platform (please refer to ./system/flcore/clients/clientavg.py for details).

Environments

With the installed conda, we can run this platform in a conda virtual environment called fl_torch. Note: due to the code updates, some modules are required to install based on the given *.yml.

# current version
conda env create -f env.yml # for Linux

# old version
cd ./system
conda env create -f env_linux.yml # for linux
# conda env create -f env_win.yml # for windows

Datasets (updating)

Except for the Synthetic dataset (without update anymore), I currently using six famous datasets: MNIST, Fashion-MNIST, Cifar10, Cifar100, AG_News and Sogou_News, they can be easy split into IID and Non-IID version. Since some codes for generating datasets such as splitting are the same for all datasets, I move these codes into ./utils/dataset_utils.py. Now it is easy to add other datasets to this FL platform. If you need another data set, just write another code to download it and then using the utils.

In Non-IID setting, three situations exist. The first one is the pathological Non-IID setting, the second one is practical Non-IID setting and the third one is feature skew Non-IID. In the pathological Non-IID setting, for example, the data on each client only contains the specific number of labels (maybe only two labels), though the data on all clients contains 10 labels such as MNIST dataset. In the practical Non-IID setting, Dirichlet distribution is utilized (please refer to this paper for details). In the feature skew Non-IID, specific Gaussian noise is added to each client according to their IDs. We can input balance for the iid setting, where the data are uniformly distributed.

Models

Algorithms (updating)

How to start simulating

  • Build dataset: Datasets

  • Train and evaluate the model:

    cd ./system
python main.py -data mnist -m cnn -algo FedAvg -gr 2500 -did 0 -go cnn # for FedAvg and MNIST

    Or you can uncomment the lines you need in ./system/auto_train.sh and run:

    cd ./system
sh auto_train.sh

  • Plot the result test accuracy and training loss curves and save them to figures:

    python plot.py

    Then check the figures in ./figures.

Note: All the hyper-parameters have been tuned for all the algorithms, which are recorded in ./system/auto_train.sh

Practical setting

If you need to simulate FL in a practical setting, which includes client dropout, slow trainers, slow senders, and network TTL, you can set the following parameters to realize it.

  • -cdr: The dropout rate for total clients. The selected clients will randomly drop at each training round.
  • -tsr and -ssr: The rates for slow trainers and slow senders among all clients. Once a client was selected as "slow trainers", for example, it will always train slower than the original one. So does "slow senders".
  • -tth: The threshold for network TTL (ms).

Easy to extend

This platform is easy to extend both dataset and algorithm.

  • To add a new dataset into this platform, all you need to do is writing the download code and using the utils the same as ./dataset/generate_mnist.py (you can also consider it as the template).

  • To add a new algorithm, you can utilize the class server and class client, which are wrote in ./system/flcore/servers/serverbase.py and ./system/flcore/clients/clientbase.py, respectively.

  • To add a new model, just add it into ./system/flcore/trainmodel/models.py.

  • If you have an individual optimizer while training, please add it into ./system/flcore/optimizers/fedoptimizer.py
