Large-scale Bayesian Structure Learning for Gaussian Graphical Models using Marginal Pseudo-likelihood

no code implementations30 Jun 2023 Reza Mohammadi, Marit Schoonhoven, Lucas Vogels, S. Ilker Birbil

Our simulation study indicates that the proposed algorithms, particularly for large-scale sparse graphs, outperform the leading Bayesian approaches in terms of computational efficiency and precision.
