The Jensen-Shannon divergence (JS) measures how much the label distributions of different facets diverge from each other entropically. It is based on the Kullback-Leibler divergence, but it is symmetric. The formula for the Jensen-Shannon divergence is as follows: ...
In this paper, we present an improved Jensen-Shannon divergence (JSD) based spatiogram similarity measure. The spatial-color joint probability distribution of the pixels corresponding to each bin is regarded as a weighted Gaussian distribution. Then, the similarity of corresponding bin of two spatio...
JS散度(Jensen–Shannon divergence) 1. 概述 KL散度存在不对称性,为解决这个问题,在KL散度基础上引入了JS散度。 JS(P1∥P2)=12KL(P1∥P1+P22)+12KL(P2∥P1+P22)JS(P1‖P2)=12KL(P1‖P1+P22)+12KL(P2‖P1+P22) JS散度的值域范围是[0,1],相同则是0,相反为1...
JS divergence是Kullback-Leibler divergence的一个变种,转换方式如下: J(P,Q)=1/2*(D(P∣∣R)+D(Q∣∣R)) 这里的R=1/2*(P+Q) D(P||R)就是KL divergence flexmix是一个计算KL divergence的R包,manual地址如下:
In particular, for this purpose we put forward the Jensen-Shannon divergence ($JSD$) as a metric, which is bounded and has an intuitive information-theoretic interpretation. We demonstrate, via a straightforward procedure making use of the $JSD$, that it can be used as part of maximum ...

This paper describes the Jensen-Shannon divergence (JSD) and Hilbert space embedding. With natural definitions making these considerations precise, one finds that the general Jensen-Shannon divergence related to the mixture is the minimum redundancy, which can be achieved by the observer. The set of...
The present work is devoted to review the main properties of a distance known as the Jensen‐Shannon divergence (JSD) in its classical and quantum version. We present two examples of application of this distance: in the first one we use it as a quantifiers of the stochastic resonance ...
