The kullback-leibler divergence
http://hanj.cs.illinois.edu/cs412/bk3/KL-divergence.pdf WebIn probability theory and statistics, the Jensen – Shannon divergence is a method of measuring the similarity between two probability distributions. It is also known as information radius ( IRad) [1] [2] or total divergence to the average. [3] It is based on the Kullback–Leibler divergence, with some notable (and useful) differences ...
