沃瑟斯坦距离提供了一个概率度量空间的度量。我们考虑有限集合$chi = {1, dots,n}$上的所有概率测度的空间$Omega$,其中$n$是一个正整数。1-Wasserstein距离$W_1(mu)
Wasserstein distances provide a metric on a space of probability measures. We consider the space $Omega$ of all probability measures on the finite set $chi = {1, dots ,n}$ where $n$ is a positive integer. 1-Wasserstein distance, $W_1(mu, u)$ is a function from $Omega imes Omega$ to $[0,infty)$. This paper derives closed form expressions for the First and Second moment of $W_1$ on $Omega imes Omega$ assuming a uniform distribution on $Omega imes Omega$.
