Data-driven methods c an then be used to approximate a finite-dimensional Koopman operator\, whi ch is particularly useful for system identification\, control\, and state estimation tasks. However\, approximating large Koopman operators is numer ically challenging\, leading to unstable Koopman operators being identifie d for otherwise stable systems. This talk will present a selection of tech niques to regularize the Koopman regression problem\, including a novel H- infinity norm regularizer. In particular\, how to re-pose the system ident ification problem in order to leverage numerically efficient optimization tools\, such as linear matrix inequalities\, will be presented. This talk is based on the pre-print arxiv.\n\nhttps://dms.umontreal.ca/~mathapp/inde x_fr.html\n\n \n\n \n\nSeminar Applied Mathematics/Mathématiques appliquée s\n Zoom/ Please contact : damien.tageddine [at] mail.mcgill.ca\n DTSTART:20220912T200000Z DTEND:20220912T210000Z SUMMARY:James Forbes\, 9IÖÆ×÷³§Ãâ·Ñ URL:/mathstat/channels/event/james-forbes-mcgill-34176 8 END:VEVENT END:VCALENDAR
