2013-06-03 · 1. The KL distance between two Gaussians $f$ and $g$ is $D_{KL}( f || g ) = {1\over2}\left( \log\left( { \det(\Sigma_g)}\over { \det(\Sigma_f)}\right) + Tr( \Sigma_g^{-1} \Sigma_f) + ||\mu_f – \mu_g||_g^2 -d \right)$ where $d$ is the dimension of the space, $\Sigma$ is the covariance matrix, $\mu$ is the mean, $Tr$ is the trace, and

extend the KL divergence based fault detection to dynamic systems. 2017-06-29 · In chapter 3 of the Deep Learning book, Goodfellow defines the Kullback-Leibler (KL) divergence between two probability distributions P and Q. And although the KL divergence is often used as measuring the "distance" between distributions, it is actually not a metric because it is asymmetric. So the KL divergence between two Gaussian distributions with di erent means and the same variance is just proportional to the squared distance between the two means. In this case, we can see by symmetry that D(p 1jjp 0) = D(p 0jjp 1), but in general this is not true. 2 A Key Property 2013-07-10 · The function kl.norm of the package monomvn computes the KL divergence between two multivariate normal (MVN) distributions described by their mean vector and covariance matrix.

My result is obviously wrong, because the KL is not 0 for KL(p, p).
