This chapter discusses the inner workings of neural network processing. It shows how a network is built, trained, and tested.

Function to Be Approximated

Let’s consider the function y(x) = x² shown in Figure 2-1. However, let’s pretend that the function formula is not known and that the function values are given to us by their values at four points.
