Normalized gaussian wasserstein distance代码
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 … Web13 de mai. de 2024 · $\begingroup$ There are dozen of ways of computing the Wasserstein distance. Many of those are actually algorithms designed to solve the more general optimal transport problem. Arguably the most common ones are the network simplex algorithm (exact) or the Sinkhorn algorithm (approximate).
