作为第一个尝试,我们来算两个高斯分布的KL散度(Kullback-Leibler divergence)。KL散度算是最常用的分布度量之一了,因为它积分之前需要取对数,这对于指数簇分布来说通常能得到相对简单的结果。此外它还跟“熵”有着比较紧密的联系。 计算结果 两个概率分布的KL散度定义为 KL(p(\boldsymbol{x})\Vert q(\bold...

Consider the problem of representing a distribution <tex>$\pi$</tex> on a large alphabet of size <tex>$k$</tex> up to fidelity <tex>$\varepsilon$</tex> in Kullback-Leibler (KL) divergence. Heuristically, arguing as for quadratic loss in high dimension, one expects that about <tex>$...
One way to measure the dissimilarity of two probability distributions, p and q, is known as the Kullback-Leibler divergence (KL divergence) or relative entropy. — Page 57, Machine Learning: A Probabilistic Perspective, 2012. The log can be base-2 to give units in “bits,” or the natural...
