New decentralized EM algorithms improve Gaussian mixture modeling in federated learning

Researchers have developed new decentralized algorithms for Gaussian mixture models in federated learning settings. These methods, including a momentum-based approach (MNEM) and a semi-supervised variant (semi-MNEM), address challenges posed by heterogeneous data distribution and partial labeling. Theoretical analysis suggests MNEM can achieve asymptotic efficiency comparable to centralized methods, while semi-MNEM enhances convergence speed, as demonstrated through simulations and an analysis of a chest X-ray dataset.
