WebIn mathematics, the Wasserstein distance or Kantorovich–Rubinstein metric is a distance function defined between probability distributions on a given metric space.It is named after Leonid Vaseršteĭn.. Intuitively, if each distribution is viewed as a unit amount of earth (soil) piled on , the metric is the minimum "cost" of turning one pile into the other, which is … Web1 de fev. de 2024 · Since the normalized Wasserstein’s optimization (3) includes mixture proportions π (1) and π (2) as optimization variables, if two mixture distributions have similar mixture components with different mixture proportions (i.e. P X = P G, π (1) and P Y = P G, π (2)), although the Wasserstein distance between the two can be large, the introduced …
