Ahlad Kumar’s YouTube channel

If you were on YouTube trying to learn about variational autoencoders (VAEs) as I was, you might have come across Ahlad Kumar’s series on the topic. In his second video (embedded above), he explained KL divergence which we will later see is in fact a building block of the loss function in the VAE. This article aims to bridge ideas in probability theory as you may have learnt in school to those in the video. We will then re-look at the proof for KL divergence between 2 multivariate Gaussians (a.k.a normal distributions).
