Laplace Approximation
Laplace approximation is a widely used technique in Bayesian inference that approximates complex posterior distributions with simpler Gaussian distributions, facilitating efficient uncertainty quantification and model selection. Current research focuses on improving the accuracy and scalability of Laplace approximations, particularly within deep learning models, by addressing issues like variance reduction, handling high-dimensional data, and incorporating informative priors, including those derived from generative models or Gaussian processes. These advancements are significant because they enable more robust and reliable Bayesian inference in various applications, ranging from meta-learning and Bayesian optimization to data assimilation and uncertainty estimation in deep neural networks.
