Earth movers distance metric
WebA metric on a set X is a function (called the distance function or simply distance) d : X × X → R+ (where R+ is the set of non-negative real numbers ). For all x, y, z in X, this function is required to satisfy the following conditions: d ( x, y) ≥ 0 ( non-negativity) d ( x, y) = 0 if and only if x = y ( identity of indiscernibles.
