Diffusion Models are generative models just like GANs. In recent times many state-of-the-art works have been released that build on top of diffusion models such as #dalle or #imagen. In this video I give a detailed explanation of how they work. At first I explain the fundamental idea of these models and later we dive deep into the math part. I try to explain all of this on a really easy & intuitive level. After the math derivation, we look at the results from different papers and how they compare to other methods.
