Introduction to Artificial Neural networks (3)--An application example of multilayer artificial neural network

1 Introduction

An XOR operation is a commonly used calculation in a computer:

0 XOR 0 = 0

0 XOR 1 = 1

1 XOR 0 = 1

1 XOR 1 = 0

We can use the code in the first article to calculate this result Http://files.cnblogs.com/gpcuster/ANN1.rar (need to modify the training set), we can find that the results of learning does not satisfy us, because the single layer of neural network learning ability is limited , you need to use more complex networks to learn.

In this article, we will use a new multilayer neural network to learn.

2 use and description of the sample program

The use of this program and the introduction of Artificial neural network (1)-Single-layer artificial neural network applications similar, you can refer to http://www.cnblogs.com/gpcuster/archive/2008/05/22/1204456.html

But one more computational operation (XOR), as shown in figure:
