System identification and data-driven modelling


Developing algorithms for the identification of mathematical models describing the evolution of dynamical systems which are difficult to model only using first principles. We are also interested in considering the problem of quantifying the uncertainty associated with the estimated models and providing systematic means for introducing prior information in the identification.


We build our approaches on established subjects in the field of systems theory such as system identification and estimation and we foster their integration with techniques from the related fields of statistical learning theory and kernel-based methods.
