Personalized Subgraph Federated Learning

Official Code Repository for the paper - Personalized Subgraph Federated Learning (ICML 2023): https://arxiv.org/abs/2206.10206.

Requirement

• Python 3.9.16
• PyTorch 2.0.1
• PyTorch Geometric 2.3.0
• METIS (for data generation), https://github.com/james77777778/metis_python

Data Generation

Following command lines automatically generate the dataset.

$ cd data/generators
$ python disjoint.py
$ python overlapping.py

Run

Following command lines run the experiments for both FedAvg and our FED-PUB.

$ sh ./scripts/disjoint.sh [gpus] [num_workers]
$ sh ./scripts/overlapping.sh [gpus] [num_workers]

• gpus: specify gpus to use
• num workers: specify the number of workers on gpus (e.g. if your experiment uses 10 clients for every round then use less than or equal to 10 workers). The actual number of workers will be num_workers + 1 (one additional worker for a server).

Example

$ sh ./scripts/disjoint.sh 0,1 10
$ sh ./scripts/overlapping.sh 0,1 10
