Web2 Aug 2011 · Kullback-Leibler divergence (KL divergence) [1-2] is a measure of the distance between two probability distributions P and Q. It has many other names including the relative entropy. For two distributions and on , it is defined as follows: If and are not discrete, the above sum is understood as a Lebesgue integral. Contents [ hide] WebThe Kullback Leibler (KL) divergence is a widely used tool in statistics and pattern recognition. The KL divergence between two Gaussian mixture models (GMMs) is frequently needed in the fields of speech and image recognition. Unfortunately the KL divergence between two GMMs is not analytically tractable, nor does any efficient computational …
