Spectral Sparsification of Laplacian-Constrained Gaussian and Hüsler-Reiss Graphical Models
Ignacio Echave-Sustaeta Rodríguez, Aida Abiad, Frank Röttger
Graph Laplacians encode graph structures in matrix form, and thus facilitate the application of linear algebra to graph theory. In statistics, two related families of probabilistic…

Learning Gaussian Graphical Models under Total Positivity via Spectral Graph Sparsification
Ignacio Echave-Sustaeta Rodríguez, Aida Abiad, Frank Röttger
Many practical data analysis tasks reduce to learning, from observed samples, how a collection of variables depend on each other. A widely used approach is to fit a Gaussian graphi…
