 Obiettivi dell'insegnamento
 The goal of the course is to enable students to extract (“learn”) from measured data useful information. The course covers advanced topics of data-driven black-box system identification and virtual  sensing.

 Risultati di apprendimento attesi
 Through theoretical lectures and numerical-exercises sessions, the students are expected to: Understand the fundamental problems that can be encountered while extracting information from a finite set of observations taken from an unknown system. Learn the main tools of system identification and virtual sensing. Be able to formulate identification problems corresponding to different applications. Understand a range of algorithms along with their strengths and weaknesses. Be able to apply suitable algorithms to solve application problems. Be able to read current research papers and understand the issues raised by current research in the field.

 Argomenti trattati
 The program of the course is as follows. Part 1: Basic concepts of stochastic processes ARMA and ARMAX classes of parametric models for time series and for Input/Output systems Parameter identification of ARMA and ARMAX models Analysis of identification methods Model validation and pre-processing Part 2 Non-parametric system identification: the subspace-based state-space approach Kalman Filter: prediction, virtual-sensing and gray-box system identification Analysis and design of closed-loop systems using the minimum-variance approach Non-linear system-identification: parametric nonlinear fitting; N-ARMAX models; optimal design of basis functions using Principal-Component-Analysis Frequency-domany parametric estimation of models from data Recursive system identification: extension of system-identification to time-varying systems

 Prerequisiti
 Familiarity with basic concepts of computer science (algorithms and complexity) and dynamical systems theory. Mathematical maturity in linear algebra and probability theory.

 Modalità di valutazione
 The exam will be a written test in one of the official available dates. The exam will consist of both theoretical questions and simple  (i.e., no computer-aided) exercises. The final marks will be awarded based on correctness of the answers, appropriateness of technical terminology and clarity of exposition. Specifically, the students will be asked to: show their understanding of the main problems (and the corresponding countermeasures) in the field of data-driven modeling in general; select and describe the most appropriate tools for a given application; use analytical methods to solve system-identification problems of moderate complexity.
