www.cs.princeton.edu4 Kullback-Leibler Divergence We measure the closeness of the two distributions with Kullback-Leibler (KL) divergence. This comes from information theory, a eld that has deep links to statistics and machine learning. (See the books \Information Theory and Statistics" by Kullback and \Information Theory, Inference, and Learning Algorithms" by ...

arxiv.orgwhere KL[q()jjp()] is the Kullback-Leibler divergence between q() and p(). We further take a Gaussian prior p(Z) = Q i p(z i) = Q i N(z i j0;I). For very sparse A, it can be beneficial to re-weight terms with A ij = 1 in Lor alternatively sub-sample terms with A ij = 0. We choose the former for the following experiments.

hanj.cs.illinois.edubutions, it is not a distance measure. This is because that the KL divergence is not a metric measure. It is not symmetric: the KL from p(x) to q(x) is generally not the same as the KL from q(x) to p(x). Furthermore, it need not satisfy triangular inequality. Nevertheless, DKL(P||Q) is a …
