This is done by seeking to minimize each class's average deviation from the class mean, while maximizing each class's deviation from the means of the other classes. In other words, the method seeks to reduce the variance within classes and maximize the variance between classes. great wall lerwick menuWebAnother suitable distance is the Wasserstein distance, which is induced by a Riemannian metric and is related with the minimal transportation cost.
