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.

WebThe Earth Mover's Distance (EMD) is a method to evaluate dissimilarity between two multi-dimensional distributions in some feature space where a distance measure between single features, which we call the ground distance is given. The EMD ``lifts'' this distance from individual features to full distributions. WebEarth mover's distances on discrete surfaces .
