Syllabus

In the first part (3 lectures), we will expose the bases of machine learning (supervised/unsupervised ML, optimization, regularization, neural networks, deep neural networks etc.) as well as the Python tools required to initiate a project (PyTorch).

After this short introduction we will present a set of projects (some are listed below) on which the students can work in groups of two during the whole semester. All the topics are linked with machine learning applied to a physics problem.
After some bibliographical work, students will have to find appropriate datasets and pre-process them to build and implement an algorithm that answers the problem. The work is done in partial autonomy with weekly interactions planned for each group with the supervisors.

 

A non-exhaustive (and not definitive) list : 
Image retirée. Estimating cosmological parameters from halo distribution in cosmological simulations, 
Image retirée. Augmenting dark matter simulations’ resolution by deep generative models, 
Image retirée. Deep symbolic regression for new physics, 
Image retirée. Contrastive divergence learning in energy-based models, 
Image retirée. Applications of autoregressive networks in statistical mechanics problems, 
Image retirée. Accelerated sampling of energy landscapes with neural networks.

Prerequisites

Python basis for numerical analysis (ML-specific libraries are not required), knowledge in statistics (estimation, inference).

Evaluation

The exam consists of a 20-minute oral presentation of the proposed solution but also of the scientific approach followed throughout the project.
