These are a set of tutorials made for 2025 IAIFI Summer school, in companian with the lecture by Aleksandra Ćiprijanović. The tutorials can be found under the tutorials directory, and the solutions to both can be found under solutions. If, by chance, you are struggling to train the models, pre-trained models can be found in pretrained_models.zip.
These notebooks were able to run in
The only package you will likely not have is geomloss, which we use to efficiently compute statistical distances (sinkhorn divergences, MMD). You should be able to run a simple pip install if you don't have it. If you have many things to install, you can do `pip install requirements_X.txt', where
Tutorial 1: Comparison between maximum mean discrepancy (MMD) and domain adversarial neural networks (DANNs), for generalizing between the MNIST and MNIST-M datasets. In this tutorial, you'll see firsthand how DA can improve generalization performance.
Lecture 2: Implementing the Sinkhorn divergence and studying automated ways to omit hyperparmaeter tuning when training models with domain adaptation. This tutorial uses real galaxy images from the Sloan Digital Sky Survey (SDSS) and Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Surveys. These will be download from this Zenodo link. I would use Chrome to download the data (I had issues on Safari).
The focus is on conceptual understanding and application rather than PyTorch syntax. I've sprinkled questions and directions for further exploration throughout the notebooks; and my hope is that you can do some self-exploration and deep thinking in whatever seems interesting to you and most relevant for your own work.
