Learning Large-Scale MTP $_{2}$ Gaussian Graphical Models via Bridge-Block Decomposition

Xiwen Wang, Jiaxi Ying, Daniel P. Palomar

This paper studies the problem of learning the large-scale Gaussian graphical models that are multivariate totally positive of order two ( $MTP_{2}$ ). By introducing the concep…

Network Topology Inference with Sparsity and Laplacian Constraints

Jiaxi Ying, Xi Han, Rui Zhou +2

We tackle the network topology inference problem by utilizing Laplacian constrained Gaussian graphical models, which recast the task as estimating a precision matrix in the form of…
