Earth mover’s distances on discrete surfaces
WebThe Earth mover’s distance is a distance measure between probability distributions. If we consider each probability mass function as a histogram of dirt, it is equal to the amount of work needed to optimally move the dirt of one histogram into the shape of the other. For categorical data, the “distance” between unequal symbols is unitary. WebThe 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.
