Black Box Variational Inference

Black-box variational inference (BBVI) is a technique for approximating complex posterior distributions in Bayesian models, aiming to improve efficiency and scalability compared to traditional methods. Current research focuses on enhancing BBVI's reliability and speed through improved gradient estimators (e.g., using James-Stein estimators or acceptance sampling), more efficient mixture models (like MISVAE), and refined optimization strategies (including proximal stochastic gradient descent and second-order methods). These advancements are significant because they make BBVI more robust and applicable to high-dimensional problems across diverse fields, including Bayesian phylogenetic inference and machine learning.
