Warnick speaks at University of Tennessee

August 13, 2015

Continuing an ongoing dialog with Professor Donatello Materassi on representations of network systems, Professor Warnick accepted an invitation to speak in the Department of Electrical Engineering and Computer Science at the University of Tennessee on August 13, 2015. Warnick and Materassi independently developed similar representations for network systems characterized by the relationships among a system’s observed signals, and this visit gave the two researchers a chance to compare and contrast their models. In his talk, Warnick illustrated how both of these representations differ from other representations of network systems, especially those characterized by the interconnection of subsystems. “The key difference is that our representations allow for the possibility of shared state among component subsystems, while interconnections of subsystems explicitly forbid shared state. This has dramatic consequences on the information cost for identifying network structure from data,” Warnick said. Warnick and Materassi are co-organizers and co-chairs of a series of special invited sessions on “Network Semantics, Representations, Identification and Control” at the upcoming Conference on Decision and Control in Osaka, Japan in December, 2015.
