EMD

The Earth Mover's Distance The Earth Mover's Distance (EMD) is a method to evaluate dissimilarity between two multi-dimensional distributions in some feature space where a distance measure between single features, which we call the ground distance is given. The EMD ``lifts'' this distance from individual features to full distributions. Intuitively, given two distributions, one can be seen as a mas
