Learning Gaussian Graphical Models Using Discriminated Hub Graphical Lasso
ICASSP 2018accepted
We develop a new method called Discriminated Hub Graphical Lasso (DHGL) based on Hub Graphical Lasso (HGL) by providing the prior information of hubs. We apply this new method in two situations: with known hubs and without known hubs. Then we compare DHGL with HGL using several measures of performan…
