The aim of this book is to handle different application problems of science and engineering using expert Artificial Neural Network (ANN). As such, the book starts with basics of ANN along with different mathematical preliminaries with respect to algebraic equations. Then it addresses ANN based methods for solving different algebraic equations viz. polynomial equations, diophantine equations, transcendental equations, system of linear and nonlinear equations, eigenvalue problems etc. which are the basic equations to handle the application problems mentioned in the content of the book. Although there exist various methods to handle these problems, but sometimes those may be problem dependent and may fail to give a converge solution with particular discretization. Accordingly, ANN based methods have been addressed here to solve these problems. Detail ANN architecture with step by step procedure and algorithm have been included. Different example problems are solved with respect to various application and mathematical problems. Convergence plots and/or convergence tables of the solutions are depicted to show the efficacy of these methods. It is worth mentioning that various application problems viz. Bakery problem, Power electronics applications, Pole placement, Electrical Network Analysis, Structural engineering problem etc. have been solved using the ANN based methods.

The art of applying mathematics to real-world dynamical problems such as structural dynamics, fluid dynamics, wave dynamics, robot dynamics, etc. can be extremely challenging. Various aspects of mathematical modelling that may include deterministic or uncertain (fuzzy, interval, or stochastic) scenarios, along with integer or fractional order, are vital to understanding these dynamical systems. Mathematical Methods in Dynamical Systems offers problem-solving techniques and includes different analytical, semi-analytical, numerical, and machine intelligence methods for finding exact and/or approximate solutions of governing equations arising in dynamical systems. It provides a singular source of computationally efficient methods to investigate these systems and includes coverage of various industrial applications in a simple yet comprehensive way.

Differential equations play a vital role in the fields of engineering and science. Problems in engineering and science can be modeled using ordinary or partial differential equations. Analytical solutions of differential equations may not be obtained easily, so numerical methods have been developed to handle them. Machine intelligence methods, such as Artificial Neural Networks (ANN), are being used to solve differential equations, and these methods are presented in Artificial Neural Networks for Engineers and Scientists: Solving Ordinary Differential Equations. This book shows how computation of differential equation becomes faster once the ANN model is properly developed and applied.

Differential equations are ubiquitous in science and engineering for describing the natural world and often appear as nonlinear differential equations. Unfortunately, there is no general method for solving all types of nonlinear differential equations. This work uses a machine learning process called deep neural networks (DNNs) to create a solver for the Ginzburg-Landau equation regardless of the boundary conditions or the right-hand side. This method overcomes challenges to previous methods that require recomputing the solution again for every change in the boundary conditions and right-hand side of the equation. The method develops a versatile solver capable of finding a solution using only the form of the differential equation without a predefined right-hand side or boundary conditions. Systematically varying the architecture of the network, the characteristics of the input data, the loss function optimized over, and the network's hyperparameters reveal that the method can find a general solution across a diverse range of boundary conditions and right-hand sides. The network can consistently find accurate approximations of slowly oscillating data and highly oscillating data built from many terms of the Fourier series. The model can generalize performance from training data to test data, indicating its success in creating a general inverse differential operator that solves the equation. For data with many oscillations and small magnitudes, the network suffers from the vanishing gradient problem. These challenges are addressed by implementing strategies such as batch normalization, varying initialization schemes, changing activation functions, modifying the network architecture, and altering the loss function. These changes help mitigate the problem, leading to more stable and robust solutions to the initial hyperparameters of the model. However, the vanishing gradient problem persists despite these changes. Developing a solver that works for nonlinear equations would be pivotal in developing a theory for solving differential equations, saving computational time and resources, and facilitating real-time applications of the network without retraining.

Neural networks and neural dynamics are powerful approaches for the online solution of mathematical problems arising in many areas of science, engineering, and business. Compared with conventional gradient neural networks that only deal with static problems of constant coefficient matrices and vectors, the authors’ new method called zeroing dynamics solves time-varying problems. Zeroing Dynamics, Gradient Dynamics, and Newton Iterations is the first book that shows how to accurately and efficiently solve time-varying problems in real-time or online using continuous- or discrete-time zeroing dynamics. The book brings together research in the developing fields of neural networks, neural dynamics, computer mathematics, numerical algorithms, time-varying computation and optimization, simulation and modeling, analog and digital hardware, and fractals. The authors provide a comprehensive treatment of the theory of both static and dynamic neural networks. Readers will discover how novel theoretical results have been successfully applied to many practical problems. The authors develop, analyze, model, simulate, and compare zeroing dynamics models for the online solution of numerous time-varying problems, such as root finding, nonlinear equation solving, matrix inversion, matrix square root finding, quadratic optimization, and inequality solving.
