Well known as an … 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.

WebSep 6, 2024 · The Earth Mover’s Distance is the minimum amount of work involved, where “amount of work” is the amount of earth you have to move multiplied by the distance you have to move it. The EMD can also be shown to be equal to the area between the two empirical CDFs. The EMD is a good tool for distributions with long tails. WebApr 8, 2024 · The Earth mover’s distance is a type of distance where the position and weight of the points in an N-dimensional space is critical.
