3. KL divergence Very First, we should be clear that A, B inDKLDKLpoints at thesame random variable X(X~A, X~B) Then, we should know the function of KL divergence, or KL distance. KL divergence represents theinformation lossgenerated by usinga choosen distribution B to fit actual dist...
The Kullback-Leibler divergence (KL) measures how much the observed label distribution of facet a, Pa(y), diverges from distribution of facet d, Pd(y). It is also known as the relative entropy of Pa(y) with respect to Pd(y) and quantifies the amount of information lost when moving ...

:attr:`reduction` = ``'mean'`` doesn't return the true kl divergence value, please use :attr:`reduction` = ``'batchmean'`` which aligns with KL math definition. In the next major release, ``'mean'`` will be changed to be the same as 'batchmean'. ...
and 84 drivers are tested. Then the driving data of each driver are regarded as a specific Gaussian mixture model (GMM), and whose parameters are estimated by using expectation maximization algorithm. Finally Monte Carlo algorithm is employed to estimate the KL divergence between GMMs, hence the ...

Bayesian learning is often hampered by large computational expense. As a powerful generalization of popular belief propagation, expectation propagation (EP) efficiently approximates the exact Bayesian computation. Nevertheless, EP can be sensitive to outliers and suffer from divergence for difficult cases...
