Using Fisher Information to bound KL divergence

WebA great many important inequalities in information theory are actually lower bounds for the Kullback–Leibler divergence. Even the Shannon-type inequalities can be considered part of this category, since the interaction information can be expressed as the Kullback–Leibler divergence of the joint distribution with respect to the product of ... 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. clearview loans phone numbehttp://www.m-hikari.com/ams/ams-2011/ams-65-68-2011/sayyarehAMS65-68-2011.pdf bluetooth 1.0b
