Posterior Approximation
Posterior approximation focuses on efficiently estimating complex probability distributions, crucial for Bayesian inference in diverse fields. Current research emphasizes developing accurate and computationally feasible methods, employing architectures like normalizing flows, diffusion models, and Markov Chain Monte Carlo (MCMC) variants, often within a variational inference framework. These advancements are improving uncertainty quantification in machine learning models, enabling more reliable predictions in applications ranging from image processing and inverse problems to scientific modeling and medical image analysis. The ultimate goal is to bridge the gap between the theoretical elegance of Bayesian methods and their practical applicability to high-dimensional, real-world problems.
