Since their development by Kingma et.al.[1] the VAE has proven to be a flexible and powerful framework for latent variable modelling. Sitting at the crossroads of classical statistical learning and deep learning, it has made an impact in many problems, from classical tasks in computer vision such as image generation, compression, super-resolution, inpainting, 3D object synthesis to other tasks such as semi-supervised learning, natural language modelling, sentence interpolation, and even practical applications to medical imaging.

We will start with a minimal introduction to latent variable models and the structure and definition of a VAE , before presenting some examples. We will then discuss some of the topics of interest in the research surrounding VAEs, looking to various techniques meant to reduce the inference gap, as well as studying the usefulness of the VAE for learning latent representations for downstream tasks. If time allows, we will present some more off-beat results.
