Flow-based models for data generation

While both VAEs (Chapter 8, Autoencoders) and GANs do a good job of data generation, they do not explicitly learn the probability density function of the input data. GANs learn by converting the unsupervised problem to a supervised learning problem.

VAEs try to learn by optimizing the maximum log-likelihood of the data by maximizing the Evidence Lower Bound (ELBO). Flow-based models differ from the two in that they explicitly learn data distribution . This offers an advantage over VAEs and GANs, because this makes it possible to use flow-based models for tasks like filling incomplete data, sampling data, and even identifying bias in data distributions. Flow-based models accomplish this by maximizing the log-likelihood estimation. To understand how, let us delve a little into its math.

Let be the probability density of data D, and let be the probability density approximated by our model M. The goal of a flow-based model is to find the...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
