A Relaxed Wasserstein Distance Formulation for Mixtures of Radially Contoured Distributions
Keyu Chen, Zetian Wang, Yunxin Zhang
Recently, a Wasserstein-type distance for Gaussian mixture models has been proposed. However, that framework can only be generalized to identifiable mixtures of general ellipticall…
