Programma dettagliato e risultati di apprendimento attesi

Data-driven dynamical systems is a new interesting field connected to modelling nonlinear systems starting from
measurements coming from the field.
The course will describe the most recent advances on numerical techniques able to make use of a set of
measurements from the fiels to extract a dynamic model of a physical process. The models then can be used both
to predict the behaviour of the system in the near future and to provide indications to control it for the best.
This is a critically important new direction, because the governing equations of many problems under
consideration by practitioners in various scientific fields are typically not known. Hence, using data to help derive,
in an optimal sense, the best dynamical system representation of a given process allows for important new
insights for both the analysis and the control of the system.
At the end of the course, the students will be able to use the proposed techniques in their own engineering field
to synthetise dynamic models of the studied phenomena, starting from a reasonably large set of measurements
coming from the field.

Note Docente
The course will be taught (25 hours) by prof. Prof. Nathan J. Kutz, University of Washington Professor Kutz was awarded the B.S. in Physics and Mathematics from the University of Washington in 1990 and the PhD in Applied Mathematics from Northwestern University in 1994. Following postdoctoral fellowships at the Institute for Mathematics and its Applications (University of Minnesota, 1994-1995) and Princeton University (1995-1997), he joined the faculty of applied mathematics and served as Chair from 2007-2015. His main research interests are related to numerical methods and scientific computing, data analysis and dimensionality reduction (PCA, POD, etc) methods, dynamical systems, bifurcation theory, linear and nonlinear wave propagation, perturbation and asymptotic methods, nonlinear analysis, variational methods, soliton theory, nonlinear optics, mode-locked lasers, fluid dynamics, Bose-Einstein condensation, neuroscience, gesture recognition and video & image processing.
