Earth mover's distance

WebWe can think of target embeddings as piles of earth, and transformed source embeddings as holes to be lled. Then the earth mover's distance computes the minimal cost of moving the earth to ll the holes. Clearly, if the two sets of embeddings align well, the earth mover's distance will be small.
