چکیده

Conditions for Global Asymptotic Stability (GAS) of a nonlinear relaxation equation realised by a Nonlinear Autoregressive Moving Average (NARMA) recurrent perceptron are provided. Convergence is derived through Fixed Point Iteration (FPI) techniques, based upon a contraction mapping feature of a nonlinear activation function of a neuron. Furthermore, nesting is shown to be a spatial interpretation of an FPI, which underpins a recently proposed Pipelined Recurrent Neural Network (PRNN) for nonlinear signal processing.

Asymptotic behavior of a system of two difference equations of exponential form

In this paper, we study the boundedness and persistence of the solutions, the global stability of the unique positive equilibrium point and the rate of convergence of a solution that converges to the equilibrium $E=(bar{x}, bar{y})$ of the system of two difference equations of exponential form: begin{equation*} x_{n+1}=dfrac{a+e^{-(bx_n+cy_n)}}{d+bx_n+cy_n}, y_{n+1}=dfrac{a+e^{-(by_n+cx_n)}}{d+...

On global asymptotic stability of fully connected recurrent neural networks

Conditions for Global Asymptotic Stability (GAS) of a nonlinear relaxation process realized by a Recurrent Neural Network (RNN) are provided. Existence. convergence, and robustness of such a process are analyzed. This is undertaken based upon the Contraction Mapping Theorein (CMT) and the corresponding Fixed Point Iteration (FPI). Upper bounds for such a process are shown to be the conditions o...

Analysis of an Asymptotic Preserving Scheme for Relaxation Systems

Abstract. We consider an asymptotic preserving numerical scheme initially proposed by F. Filbet & S. Jin [10] and G. Dimarco & L. Pareschi [9] in the context of nonlinear and stiff kinetic equations. Here, we propose a convergence analysis of such a scheme for the approximation of a system of transport equations with a nonlinear source term, for which the asymptotic limit is given by a conserva...

Comments on "Lur'e systems with multilayer perceptron and recurrent neural networks: absolute stability and dissipativity

In this paper we consider Lur'e systems where a linear dynamical system is feedback interconnected to a multilayer perceptron nonlinearity, corresponding to recurrent neural networks with two hidden layers. For this class of nonlinear systems, we present suu-cient conditions for global asymptotic stability based on quadratic and Lur'e-Postnikov Lyapunov functions. Suucient conditions for dissip...

A Trust Region Algorithm for Solving Nonlinear Equations (RESEARCH NOTE)

This paper presents a practical and efficient method to solve large-scale nonlinear equations. The global convergence of this new trust region algorithm is verified. The algorithm is then used to solve the nonlinear equations arising in an Expanded Lagrangian Function (ELF). Numerical results for the implementation of some large-scale problems indicate that the algorithm is efficient for these ...
