A known challenge when building nonlinear models from data is to limit the size of the
model in terms of the number of parameters. Especially for complex nonlinear systems …

In classical approaches of dynamic network identification, in order to identify a system
(module) embedded in a dynamic network, one has to formulate a Multi-input-Single-output …

Engineers and scientists want mathematical models of the observed system for
understanding, design, and control. Many mechanical and civil structures are nonlinear. This …
