Machine Learning: Generative Adversarial Networks (GANS)

In this crash course, we will discuss the opportunities that generative models offer, and more specifically Generative Adversarial Networks (GANs). I will explain how GANs work intuitively, and then we will dive into the paper that introduced them in 2014 (Ian J. Goodfellow et al.

). You will therefore understand how they work in a mathematical way, which will give you the foundation to implement your first GAN from scratch. We will implement in approximately 100 lines of code a generator, a discriminator and the pseudo-code described in the paper in order to train them.

We will use the Python programming language and the PyTorch framework. After training, the generator will allow us to generate synthetic images that are indistinguishable from real images. I believe that a concept is learned by doing and this crash course aims to give you the necessary basis to continue your learning of Machine Learning, PyTorch and generative models (GANS, Variational Autoencoders, Normalizing Flows, Diffusion Models,.

). At the end of this course, the participant will be able to use Python (and more particularly the PyTorch framework) to implement scientific papers and artificial intelligence solutions. This course is also intended to be a stepping stone in your learning of generative models.
