Securing Collaborative Medical AI by Using Differential Privacy: Domain Transfer for Classification of Chest Radiographs

Overview

• This is the official repository of the paper Securing Collaborative Medical AI by Using Differential Privacy: Domain Transfer for Classification of Chest Radiographs.

Introduction

...

Prerequisites

The software is developed in Python 3.10. For the deep learning, the PyTorch 1.13 framework is used. The differential privacy was developed using Opacus 1.3.

Main Python modules required for the software can be installed from ./requirements:

$ conda env create -f requirements.yaml
$ conda activate privacy_domainDP

Note: This might take a few minutes.

Code structure

Our source code for federated learning as well as training and evaluation of the deep neural networks, image analysis and preprocessing, and data augmentation are available here.

1. Everything can be run from ./main_privdom.py.

• The data preprocessing parameters, directories, hyper-parameters, and model parameters can be modified from ./configs/config.yaml.
• Also, you should first choose an experiment name (if you are starting a new experiment) for training, in which all the evaluation and loss value statistics, tensorboard events, and model & checkpoints will be stored. Furthermore, a config.yaml file will be created for each experiment storing all the information needed.
• For testing, just load the experiment which its model you need.

2. The rest of the files:

• ./data/ directory contains all the data preprocessing, augmentation, and loading files.
• ./Train_Valid_privdom.py contains the training and validation processes.
• ./Prediction_privdom.py all the prediction and testing processes.
