General info

ENS Paris-Saclay

Each course will have a part of Lecture and a part of Practical Session. The Practical Session will be based Pytorch and Keras using colab notebooks.

Please, make sure to bring your own laptop

Evaluation: mini projects

The idea is to write a report in the form of an article (~10 pages) describing a method. Plus a notebook that would allow to reproduce some experiments (but not the training). Plus a 15 min presentation (with questions included). The structure of the “article” could be:

• Introduction: description of the problem and main ideas of the current paper.
• Method and Architecture: detailed description of the method
• Data: Description of the data used for training
• Training: explain how the network is trained
• Inference: explain how the network is uses at inference time
• Experiments: present some results
• Limitations: show limitations

subjects: tentative

• Estimation de noyaux de flou lineaires: comparaison d’architectures (avec code de base)

• Foundational modeling for phisic simulation (walrus code)

• What about quantum CNNs?

• Predictive coding, does it work?
