Web14 Jan 2024 · The KL divergence between two Bernoulli distributions is: K L ( p q) B e r = p log p q + ( 1 − p) log 1 − p 1 − q According to my understanding, the KL divergence between two multivariate Bernoulli distributions p and q should be K L ( p q) B e r = ∑ i = 1 k p i log p i q i + ( 1 − p i) log 1 − p i 1 − q i WebThe Kullback-Leibler divergence has a strong relationship with mutual information, and mutual information has a number of normalized variants. Is there some similar, entropy-like value that I can use to normalize KL-divergence such that the normalized KL-divergence is bounded above by 1 (and below by 0)? probability probability-theory
