"Decentralization and its Limits"

Bahman Gharesifard
Associate Professor, Queen's University, Ontario, Canada  


Abstract: Decentralization has played a central role in control and optimization in recent years. This development has been due to the increasing size of the datasets, particularly in machine learning applications, as well as the appearance of large-scale engineering systems for which limited information is inherently embedded in the design. Examples include distributed electricity generation, autonomous transportation systems, robotic networks, wireless sensor networks for health and environmental monitoring, and large-scale social and economic networks. In this talk, by providing a very broad range of problems of interests, I demonstrate the challenges introduced by decentralization. One main objective is to showcase the fundamental limitations that decentralization places on the design of feedbacks for control systems as well algorithms for optimization tasks. The talk will be accessible for the general audience.

Bio: Bahman Gharesifard is an Assistant Professor in the Department of Mathematics and Statistics at Queen’s University. His general research interests lie within the areas of systems and controls and its intersections with a variety of subjects in mathematics. His recent research is focused on distributed control and optimization, where the control input is generated in a decentralized manner, by a group of individuals each with limited information about the state of the system. 

In 2019 he received the CAIMS-PIMS Early Career Award, which included an invitation to speak at the 2019 Canada Society of Applied and Industrial Mathematics Annual Meeting. He also received an NSERC Accelerator Supplement.

He received the Engineering and Applied Science First Year Instructor Teaching Award from the Engineering Classes of 2018 and 2020 for the winter terms of 2015 and 2017. In 2014, he was shortlisted for the Frank Knox Award for Excellence in Teaching at Queen’s university.
