Joint Association Graph Screening and Decomposition for Large-scale Linear Dynamical Systems

no code implementations17 Nov 2014 Yiyuan She, Yuejia He, Shijie Li, Dapeng Wu

In particular, our method can pre-determine and remove unnecessary edges based on the joint graphical structure, referred to as JAG screening, and can decompose a large network into smaller subnetworks in a robust manner, referred to as JAG decomposition.
