Because of the relation KL(P||Q) = H(P,Q) - H(P), the Kullback-Leibler divergence of two probability distributions P and Q is also named Cross Entropy of two probability distributions P and Q. So the KL divergence between two Gaussian distributions with di erent means and the same variance is just proportional to the squared distance between the two means. In this case, we can see by symmetry that D(p 1jjp 0) = D(p 0jjp 1), but in general this is not true. 2 A Key Property KLD: Kullback-Leibler Divergence (KLD) Description. This function calculates the Kullback-Leibler divergence (KLD) between two probability distributions, and has many uses, such as in lowest posterior loss probability intervals, posterior predictive checks, prior elicitation, reference priors, and Variational Bayes. カルバック・ライブラー情報量. カルバック・ライブラー情報量 （カルバック・ライブラーじょうほうりょう、カルバック・ライブラー・ダイバージェンス、 英: Kullback–Leibler divergence ）とは、 確率論 と 情報理論 における2つの 確率分布 の差異を計る尺度である。.
대개 $D_{KL}(p | q)$ 또는 $KL( p| q)$로 표현합니다. KL-Divergence는 비대칭함수로 D KL ( p || q ) 와 D KL ( q || p )의 값이 다릅니다. KL-Divergence는 직관적으로 두 확률분포의 거리 같은 느낌을 줍니다. 하지만, 비대칭이기 때문에 두 분포 사이의 거리라고 표현하기는 어렵습니다.
= 0, otherwise p log p.

Share. The KL divergence is also a key component of Gaussian Mixture Models and t-SNE. the KL divergence is not symmetrical. a divergence is a scoring of how one distribution differs from another, where calculating the divergence for distributions P and Q would give a different score from Q and P. The KL divergence is a non-symmetric measure of the directed divergence between two probability distributions P and Q. It only fulfills the positivity property of a distance metric .

KL-divergence는 $p$와 $q$의 cross entropy에서 $p$의 엔트로피를 뺀 값입니다. 결과적으로 두 분포의 차이를 나타냅니다. KL-divergence의 정확한 식은 이렇습니다.

Note that the kullback_leibler_divergence expects all the class probabilities, even in the case of binary classification (giving just the positive class probability is not enough). Kullback-Leibler distance is the sum of divergence q(x) from p(x) and p(x) from q(x).
I have two probability distributions. How should I find the KL-divergence between them in PyTorch?
