Abstract

Learning theory and system identification are the art and science of building mathematical models of dynamic systems from observed input-output data. It can be seen as the interface between the real world of applications and the mathematical world of control theory and model abstractions. The core of estimating models is statistical theory. This talk will report the relationships between learning theory and identifying dynamical systems from noisy observations. A sparse algorithm for linear system identification from noisy measurements is explored. We are sure that the system identification community would benefit from an influx of new ideas from statistical learning theory.
