WebDec 20, 2024 · In summary, maximizing the log-likelihood is arguably a natural objective, and KL-divergence (with 0 log 0 defined as 0) comes up because of its equivalence to log-likelihood under typical settings, rather than explicitly being motivated as the objective.

WebIn mathematical statistics, the Kullback–Leibler divergence (also called relative entropy and I-divergence [1] ), denoted , is a type of statistical distance: a measure of how one probability distribution P is different from a second, reference probability distribution Q. [2] [3] A simple interpretation of the KL divergence of P from Q is the … Webtractability, a tight surrogate upper bound of the KL divergence in (2) can be derived through the variational inference [36]– ... second inequality is due to the non-negativity of the KL divergence. The bound is tight when the common information encoder, the variational distribution, and the labels information coincide, i.e., ... WebOct 1, 2024 · Based on the skewed Kullback-Leibler divergence introduced in the natural language processing, we derive the upper and lower bounds on the skewed version of the Jensen-Shannon divergence and investigate properties of them. In the process, we generalize the Bretagnolle-Huber inequality that offers an upper bound on the skewed … can you get breakfast all day at bojangles
