Kl divergence factorization

WebClustering with KL-divergence may not be the best idea, because KLD is missing an important property of metrics: symmetry. Obtained clusters could then be quite hard to … WebSome of them are Generalized Kullback–Leibler divergence, frobenius norm etc. 1. Generalized Kullback–Leibler divergence. It is a statistical measure which is used to quantify how one distribution is different from another. Closer the value of Kullback–Leibler divergence to zero, the closeness of the corresponding words increases.
