WebAug 13, 2024 · So, in this blog, we will discuss the Earthmover’s distance also known as Wasserstein metric which is more suitable for finding distance or similarity between the distributions. This concept was first introduced by Gaspard Monge in 1781, in the context of transportation theory ( Wikipedia ). Let’s discuss the main concept behind this. Webwhere p 1. When p= 1 this is also called the Earth Mover distance. The minimizer J (which does exist) is called the optimal transport plan or the optimal coupling. In case there is an optimal transport map T then J is a singular measure with all its mass on the set f(x;T(x))g.
