Web维基中也给出了两个正态分布的Wasserstein distance (p=2时候) 的公式，大家可以去看一下，正好是两部分的和，一部分代表了中心间的几何距离，另一部分代表了两个分布形状上的差异。 现在返回去看上面KL时候举的那个例子，它们之间的Wasserstein distance正好是\epsilon。 实际应用中Wasserstein distance的计算大都依赖离散化，因为目前只对有 …
WebIn computer science, the earth mover's distance ( EMD) is a distance-like measure of dissimilarity between two frequency distributions, densities, or measures over a region D .
