Researchers have developed an anchored variational inference framework designed to improve the efficiency of personalized sequential latent-state models. This new method addresses computational challenges in integrating subject-specific random effects by approximating the full conditional posterior with an evaluation at an anchor point. The framework, demonstrated through mixed hidden Markov models and mixed-effects state-space models, offers substantial computational gains while maintaining accurate estimation. AI
