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.

Earth mover’s distances on discrete surfaces

WebThe Earth mover’s distance is a distance measure between probability distributions. If we consider each probability mass function as a histogram of dirt, it is equal to the amount of work needed to optimally move the dirt of one histogram into the shape of the other. For categorical data, the “distance” between unequal symbols is unitary.

Webthe discrete version of the EMD. Indeed, the term “Earth Mover’s distance” seems to have been coined in [21] by researchers studying the discrete case, so the assumption of discrete domains is often implicit to its usage. One of the only known non-discrete cases with an explicit formula is if = R and D(x;y) = jx yj. Then W( ]; [) = Z F](y ... Webthe distance can be). The Wasserstein distance is 1=Nwhich seems quite reasonable. 2.These distances ignore the underlying geometry of the space. To see this consider Figure 1.
