WebApr 8, 2024 · The Earth mover’s distance is the distance it takes to move/transform one distribution into the other. The two characteristics of these distributions are that the points are in a space, 2D in the examples, and each point has a certain weight. By calculating the most efficient way to distribute these weights, we reach a number denoting the EMD. 9.
