Hands-on part of the Federated Learning and Privacy-Preserving ML tutorial given at VISUM 2022
A hands-on educational walkthrough of training a CelebA (Eyeglasses) image classifier with Differentially Private SGD using PyTorch and Opacus. The focus of this repo is on clarity and reproducibility through balanced subsets, deterministic preprocessing, and side-by-side baseline vs. DP training, while acknowledging real trade-offs.
This repo contains my dissertation project done during my Masters in Queen Mary University of London.
This project uses Differentially Private Stochastic Gradient Descent (DP-SGD) and autoencoder-based machine learning to securely analyze smart meter data, protecting sensitive energy patterns while preserving overall trend utility.

Experiments at the intersection of ML security & privacy: adversarial attacks/defenses (FGSM/PGD, adversarial training), differential privacy (DP-SGD, ε–δ), federated learning privacy (secure aggregation), and auditing (membership/model inversion). PyTorch notebooks + eval scripts.
Add a description, image, and links to the dp-sgd topic page so that developers can more easily learn about it.
