Researchers have explored the Variational Expectation Maximization (VEM) algorithm as a scalable method for fitting Nonlinear Mixed Effects (NLME) models, particularly when dealing with a large number of parameters. This approach, drawing from probabilistic graphical models and variational autoencoders, offers an efficient alternative to traditional computationally expensive methods. The paper details VEM's application to NLME, demonstrating its ability to handle models with over 15,000 population parameters using the Pumas statistical software. AI
