SNE minimizes the sum of Kullback-Leibler divergences over all datapoints using a gradient descent method. The cost function C is given by C =∑ i KL(PijjQi)=∑ i ∑ j pjji log p ji qjji; (2)

www.ece.tufts.edutions is the relative entropy, also sometimes called the Kullback-Leibler divergence. Definition The relative entropy between two probability distributions p(x) and q(x) is given by D(p(x)||q(x)) = X x p(x)log p(x) q(x). (30) The reason why we are interested in the relative entropy in this section is because it is related

arxiv.orgtractable family which minimises the Kullback-Leibler (KL) divergence to the true model posterior p(WjX;Y). Dropout can be interpreted as a variational Bayesian approximation, where the ap-proximating distribution is a mixture of two Gaussians with small variances and the mean of one of the Gaussians is fixed at zero.
