Normalizing Flows Invertibility
I am currently reading up on RealNVP, which has the following transformations according Lilian Weng:
$$
\begin{aligned}
\mathbf{y}_{1:d} &= \mathbf{x}_{1:d} \\
\mathbf{y}_{d+1:D} &= \mathbf{x}...

Convergence to gradient in limit of variance
I came across this equation in the original GAN paper (pg 2 https://papers.nips.cc/paper/5423-generative-adversarial-nets.pdf):
$$\lim_{\sigma \rightarrow 0}
\nabla_{\bf x} \mathbb{E}_{\epsilon \sim \...
