1. Regressor and Structure Selection : Uses of ANOVA in System Identification
Abstract : Identification of nonlinear dynamical models of a black box nature involves both structure decisions (i.e., which regressors to use and the selection of a regressor function), and the estimation of the parameters involved. READ MORE

2. Regressor Selection in System Identification using ANOVA
Abstract : The aim of this work is to nd a good method to select regressors for nonlinear system identification. A literature survey over possible methods to select the model structure for nonlinear systems, mainly autoregressive processes, is first given. The main ideas are:1. Compare estimated models, using different regressor vectors, with each other. READ MORE

3. Initialization Methods for System Identification
Abstract : In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error.

4. Non-Linear System Identification with Neural Networks
Abstract : This thesis addresses the non-linear system identification problem, and in particular, investigates the use of neural networks in system identification. An overview of different possible mode! structures is given in a common framework. READ MORE

5. Regularization for Sparseness and Smoothness : Applications in System Identification and Signal Processing
Abstract : In system identification, the Akaike Information Criterion (AIC) is a well known method to balance the model fit against model complexity. Regularization here acts as a price on model complexity. READ MORE
