SUMMARY:Understanding the Role of Network Structure in Controlling Complex Networks
DESCRIPTION:Next Wednesday June 14, 2023 at 15:45H:\nOrganized by: FAU DCN-AvH, Chair for Dynamics, Control, Machine Learning and Numerics – Alexander von Humboldt Professorship at FAU, Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)\nTitle: Understanding the Role of Network Structure in Controlling Complex Networks\nSpeaker: Prof. Dr. Jorge Cortes\nAffiliation: UC San Diego\nAbstract. Controllability of complex network systems is an active area of research at the intersection of network science, control theory, and multi-agent coordination, with multiple applications ranging from brain dynamics to the smart grid and cyber-physical systems. The basic question is to understand to what extent the dynamic behavior of the entire network can be shaped by changing the states of some of its subsystems, and decipher the role that network structure plays in achieving this. This talk examines this question in two specific instances: characterizing network controllability when control nodes can be scheduled over a time horizon and hierarchical selective recruitment in brain networks.  Regarding control scheduling, we show how time-varying control schedules can significantly enhance network controllability over fixed ones, especially when applied to large networks.  Through the analysis of a novel scale-dependent notion of nodal centrality, we show that optimal time-varying scheduling involves the actuation of the most central nodes at appropriate spatial scales. Regarding hierarchical selective recruitment, we examine network mechanisms for selective inhibition and top-down recruitment of subnetworks under linear-threshold dynamics. Motivated by the study of goal-driven selective attention in neuroscience, we build on the characterization of key network dynamical properties to enable, through either feedforward or feedback control, the targeted inhibition of task-irrelevant subnetworks and the top-down recruitment of task-relevant ones.\nWHERE?\nOnline:\nZoom meeting link\nMeeting ID: 614 4658 159 | PIN code: 914397\n
