Novel clustered federated learning based on local loss (LCFL)

Introduction

This is the code for the paper [Novel clustered federated learning based on local loss] (to add link).

The code is based on a simulation framework for federated learning fl-sim.

Requirements

To install requirements:

pip install -r requirements.txt

Usage

One can use the code in a Jupyter notebook or in command line as follows:

fl-sim configs/lcfl-rot-mnist.yml

or run in background using:

mkdir -p .logs
nohup fl-sim configs/lcfl-rot-mnist.yml > .logs/lcfl-rot-mnist.log 2>&1 & echo $! > .logs/lcfl-rot-mnist.pid

Inspection of the results

One can use the Panel widget to inspect the results in a Jupyter notebook:

%load_ext autoreload
%autoreload 2

from fl_sim.utils.viz import Panel

panel = Panel()

Results

ALL experiments were repeated 5 times with different random seeds.

Experiments on the RotatedMNIST dataset

1200 clients - ACC	1200 clients - loss
2400 clients - ACC	2400 clients - loss

Experiments on the RotatedCIFAR10 dataset

dynamic transforms - ACC	dynamic transforms - loss
no transforms - ACC	no transforms - loss

v.s. other norms

FEMNIST	RotatedMNIST
