Survey Kernel methods in system identification, machine learning and function estimation: A survey

TL;DR: A survey of kernel-based regularization and its connections with reproducing kernel Hilbert spaces and Bayesian estimation of Gaussian processes to demonstrate that learning techniques tailored to the specific features of dynamic systems may outperform conventional parametric approaches for identification of stable linear systems.
Journal ArticleDOI

On the estimation of transfer functions, regularizations and Gaussian processes-Revisited

TL;DR: A classical regularization approach, focused on finite impulse response (FIR) models, is formulated, and it is found that regularization is necessary to cope with the high variance problem.
Journal ArticleDOI

System Identification Via Sparse Multiple Kernel-Based Regularization Using Sequential Convex Optimization Techniques

TL;DR: A multiple kernel-based regularization method is proposed to handle model estimation and structure detection with short data records and it is shown that the locally optimal solutions lead to good performance for randomly generated starting points.
Journal ArticleDOI

Implementation of algorithms for tuning parameters in regularized least squares problems in system identification

TL;DR: This work investigates implementation of algorithms for solving the hyper-parameter estimation problem that can deal with both large data sets and possibly ill-conditioned computations and proposes a QR factorization based matrix-inversion-free algorithm to evaluate the cost function in an efficient and accurate way.
Journal ArticleDOI

A shift in paradigm for system identification

TL;DR: The purpose of this contribution is to provide an accessible account of the main ideas and results of kernel-based regularisation methods for system identification.
