On Model-Based Clustering With Entropic Optimal Transport
arXiv:2605.03240v1 Announce Type: cross Abstract: We develop a new methodology for model-based clustering. Optimizing the log-likelihood provides a principled statistical framework for clustering, with solutions found via the EM algorithm. However, because the log-likelihood is n…

On Model-Based Clustering With Entropic Optimal Transport
We develop a new methodology for model-based clustering. Optimizing the log-likelihood provides a principled statistical framework for clustering, with solutions found via the EM algorithm. However, because the log-likelihood is nonconvex, only convergence to stationary points ca…
