Goal: Introduce the different types of data, with a focus on time-series, and the different methodologies to apply on each type.

- Overview of the different types of data: tabular data, time series, images, graph, signals.
- Overview of the specific problems and jargon with time series and signals.
- How to get back to a “classical” ML framework?

Goal: Describe the main types of deep learning architectures, and apply them to a concrete example from life sciences.

- Introduction: what is deep learning and why is everyone doing it?
- Overview of the main types of deep learning architectures: MLP, convolutional, and transformers. When to use one or the other?
- Overview of the different training and regularization...
