• We can use the linear approximation to a function to approximate values of the function at certain points. While it might not seem like a useful Section 4-11 : Linear Approximations. In this section we're going to take a look at an application not of derivatives but of the tangent line to a function.•of function approximation. There exist multiple methods that have been established as function approximation tools, where an artificial neural network (ANNs) is one of them. According to Cybenko [1] and Hornik [2], there exists a three layer neural network that is capable in estimating an arbitrary nonlinear function f with any desired accuracy. •In the context of artificial neural networks, the rectifier is an activation function defined as the positive part of its argument: where x is the input to a neuron. This is also known as a ramp function and is analogous to half-wave rectification in electrical engineering.

Simply, a neural network is a black box that understands/models the relation between some patterns (feature vectors) and their corresponding labels (classes). The understanding phase is called "training". A trained neural network is used later on to estimate the class (label) of a test pattern, this is called the "testing" or "deployment" phase.

Universal approximation theorem states that "the standard multilayer feed-forward network with a single hidden layer, which contains finite number of hidden neurons, is a universal approximator among continuous functions on compact subsets of Rn, under mild assumptions on the activation function."

Neural network (NN) trained by traditional algorithms such as back-propagation (BP) was used to approximate function in early years [1, 2]. Yet the approximation accuracy is not high because BP has some drawbacks. First, it is easy to fall into local optimum. Second, it converges slowly. Radial Basis Function (RBF) Neural Network Control for Mechanical Systems is motivated by the need for systematic design approaches to stable adaptive control system design using neural network approximation-based techniques. The main objectives of the book are to introduce the concrete design methods and MATLAB simulation of stable adaptive RBF neural control strategies.
