Least-Squares-Based Iterative Identification Algorithm for Wiener Nonlinear Systems
This paper focuses on the identification problem ofWiener nonlinear systems.The application of the key-term separation principle provides a simplified form of the estimated parameter model. To solve the identification problem of Wiener nonlinear systems with the unmeasurable variables in the information vector, the least-squares-based iterative algorithm is presented by replacing the unmeasurab...
متن کاملNewton-Krylov Type Algorithm for Solving Nonlinear Least Squares Problems
The minimization of a quadratic function within an ellipsoidal trust region is an important subproblem for many nonlinear programming algorithms. When the number of variables is large, one of the most widely used strategies is to project the original problem into a small dimensional subspace. In this paper, we introduce an algorithm for solving nonlinear least squares problems. This algorithm i...
متن کاملA recursive algorithm for nonlinear least-squares problems
The solution of nonlinear least-squares problems is investigated. The asymptotic behavior is studied and conditions for convergence are derived. To deal with such problems in a recursive and efficient way, it is proposed an algorithm that is based on a modified extended Kalman filter (MEKF). The error of the MEKF algorithm is proved to be exponentially bounded. Batch and iterated versions of th...
متن کاملAn Efficient Algorithm for the Separable Nonlinear Least Squares Problem
The nonlinear least squares problem miny,z‖A(y)z + b(y)‖, where A(y) is a full-rank (N + `)× N matrix, y ∈ Rn, z ∈ RN and b(y) ∈ RN+` with ` ≥ n, can be solved by first solving a reduced problem miny‖ f (y)‖ to find the optimal value y∗ of y, and then solving the resulting linear least squares problem minz‖A(y∗)z + b(y∗)‖ to find the optimal value z∗ of z. We have previously justified the use o...
متن کاملNonlinear Least-squares Estimation
The paper uses empirical process techniques to study the asymptotics of the least-squares estimator for the fitting of a nonlinear regression function. By combining and extending ideas of Wu and Van de Geer, it establishes new consistency and central limit theorems that hold under only second moment assumptions on the errors. An application to a delicate example of Wu’s illustrates the use of t...
