http://alpopkes.com/files/kl_divergence.pdf Kullback-Leibler 散度 定义: Kullback-Leibler 散度用于度量两个分布的相似性(或差异)。 对于两个离散概率分布 P 和 Q ,在一个点集合 X 上 Kullback-Leibler 散度定义如下: D K L ( P ∣∣ Q ) = ∑ x ∈ X P (... ...
The RSPPs of the South and West models (p = 0.63 and 0.54, respectively) are substantially lower than those from the Midwest and Northeast models (p = 0.99 and 0.95, respectively), and the South model achieves the weakest KL divergence (1.52) of all models. We note a strong ...
