N2SID: Nuclear Norm Subspace Identification
The identification of multivariable state space models in innovation form is solved in a subspace identification framework using convex nuclear norm optimization. The convex optimization approach allows to include constraints on the unknown matrices in the data-equation characterizing subspace identification methods, such as the lower triangular block-Toeplitz of weighting matrices constructed ...
متن کاملOn-Line Identification via Haar Wavelet Expansions
This paper develops an on-line identification algorithm to estimate system parameters of non-linear continuous time systems. The algorithm, based on Haar wavelet expansions, uses the observed input-output data to estimate unknown system parameters. A recursive formula augmented with indirect matrix-inversion schemes is proposed to substantially reduce computation requisites of an existed offlin...
متن کاملSubspace system identification
We give a general overview of the state-of-the-art in subspace system identification methods. We have restricted ourselves to the most important ideas and developments since the methods appeared in the late eighties. First, the basis of linear subspace identification are summarized. Different algorithms one finds in literature (Such as N4SID, MOESP, CVA) are discussed and put into a unifyin...
متن کاملHierarchical Multiscale Modeling of Wavelet-Based Correlations
This paper presents a multiscale-based analysis of the statistical dependencies between the wavelet coefficients of random fields. In particular, in contrast to common decorrelated-coefficient models, we find that the correlation between wavelet scales can be surprisingly substantial, even across several scales. In this paper we investigate eight possible choices of statistical-interaction mode...
متن کاملAn Integrated Face Recognition Algorithm Based on Wavelet Subspace
In this paper, based on the study of the Two-Dimensional Principal Component Analysis (2DPCA), Two-Dimensional Principal Component Analysis (2DPCA) and fuzzy set theory, we propose a integrated face recognition algorithm based on wavelet subspace. This method can make good use of the advantages of each single method, and also can make up for the defect of each other. The comparison of the resul...
