Dear all and welcome back after a break of almost two weeks (last lecture day was a public holiday).

The aim this week is to discuss the math and implementations of diffusion models. These are very popular generative learning models which can be thought of as stacked variational autoencoders (VAEs). A primary advantage of diffusion models over GANs (covered next week) and VAEs is the ease of training with simple and efficient loss functions and their ability to generate highly realistic images.

Diffusion models are prominent in generating high-quality images, video, sound, etc. They are named for their similarity to the natural diffusion process in physics, which describes how molecules move from high-concentration to low-concentration areas. In the context of machine learning, diffusion models generate new data by reversing a diffusion process, i.e., information loss due to noise intervention. The main idea here is to ...
