Entropy simply makes no sense for non-discrete Jensen-Shannon divergence between two Gaussians. Also computes JS divergence between a single Gaussian pm,pv and a set of Gaussians qm,qv. Diagonal covariances are assumed. Divergence is expressed in nats.

Expected Bayes Error Rate in Supervised Classification of Spatial

The relative entropy was introduced by Solomon Kullback and Richard Leibler in 1951 as the directed divergence between two distributions; Kullback preferred the term discrimination information. The divergence is discussed in Kullback's 1959 book, Information Theory and Statistics . 2019-11-01 · The Kullback-Leibler Divergence score, or KL divergence score, quantifies how much one probability distribution differs from another probability distribution. The KL divergence between two distributions Q and P is often stated using the following notation: KL(P || Q) Where the “||” operator indicates “divergence” or Ps divergence from Q. If two distributions are identical, their KL div. should be 0. Hence, by minimizing KL div., we can find paramters of the second distribution $Q$ that approximate $P$. In this post i try to approximate the distribution $P$ which is sum of two gaussians, by minimizing its KL divergence with another gaussian distribution $Q$.
