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: JS = ½*[KL(Pa || P)...

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 ...
KL-divergence,俗称KL距离,常用来衡量两个概率分布的距离。 1. 根据shannon的信息论,给定一个字符集的概率分布,我们可以设计一种编码,使得表示该字符集组成的字符串平均需要的比特数最少。假设这个字符集是X,对x∈X,其出现概率为P(x),那么其最优编码平均需要的比特数等于这个字符集的熵: a.当log以2为底的时...
