WebApr 19, 2024 · Request PDF Estimating Sparse Networks with Hubs Graphical modelling techniques based on sparse selection have been applied to infer complex … Webis sparse: many parameters are estimated to be exactly zero. When estimating networks, this means that edges that are likely to be spurious are removed from the model, leading to networks that are simpler to interpret. Regularization there-fore jointly performs model-selection and parameter estima-tion. Regularization techniques have grown ... emogruppo gravidanza

Negative assortativity is typical of network with hubs, and such systems are typically … Webapproach. It also shows that the proposed method outperforms the rank-based PC method under sparse network or hub network structures. As a real data example, we demonstrate the efficiency of the proposed method in estimating the gene regulatory networks of the ovarian cancer study.
