Networked Dynamical Systems for Function and Learning: Paradigms for DataDriven Control and Learning in Neurosensory Systems
16 Jan 2019  Online Presentations  Contributor(s):: J. Nathan Kutz
Our objective is to use emerging datadriven methods to extract the underlying engineering principles of cognitive capability, namely those that allow complex networks to learn and enact control and functionality in the robust manner observed in neurosensory systems. Mathematically, the...

DataDriven Discovery of Governing Equations of Physical Systems
16 Jan 2019  Online Presentations  Contributor(s):: J. Nathan Kutz
We introduce a number of datadriven strategies for discovering nonlinear multiscale dynamical systems and their embeddings from data. We consider two canonical cases: (i) systems for which we have full measurements of the governing variables, and (ii) systems for which we have incomplete...
