摘要

In this chapter, we describe the flow-based generative models. The core idea is to start from the existing basic probability distribution, transform the probability distribution through a series of deep network layers, and finally define a large class of very broad probability distributions. In this way, we can compute the data distribution with close-form efficient solutions. Based on this idea, we will describe several instantiations, including normalizing flow, RealNVP, and Glow. We will also introduce flow-based model for text representation learning.
