Earth moving distance
WebApr 4, 2012 · Your "distance" is mean (f) - mean (g). To minimize the total amount of earth moved without regard to how far it is moved, a greedy algorithm achieves the optimum, which is the statistical distance between the distributions. No algorithm needed here, since you only need to compute 2 expectations. WebAbstract. We investigate the properties of a metric between two distributions, the Earth Mover's Distance (EMD), for content-based image retrieval. The EMD is based on the minimal cost that must be paid to transform one distribution into the other, in a precise sense, and was first proposed for certain vision problems by Peleg, Werman, and Rom.
