Description: BP算法
给定一个由N维向量X组成的集合，这些向量将是一个响应agent的感知处理单元计算出的特征向量。这些分量的值可以是数值，也可以是布尔值。这些动作也许是学习者所观察到的一个教师对一组输入的响应。这些相关的动作有时称为向量的“标号”或“类别”。集合与响应的标号组成“训练集合(training set)”.机器学习问题就是寻找一个函数。-BP algorithm given by the N-dimensional vector X composed of a collection, these vectors will be a response to the perceived agent processing unit eigenvector calculated. These components can be numerical values may also be a boolean value. These movements may be observed by the learner, a teacher of a group of input response. These related actions are sometimes referred to as Vector s labeling or category. Collection with the label in response to form a training set (training set) . Machine learning problem is to find a function.

Description: 本程序是BP算法的演示程序, 其中的Levenberg-Marquardt算法具有实用价值.
一、网络训练
程序默认状态是样本训练状态,现将样本训练状态下的如何训练网络进行说明:
1.系统精度:
定义系统目标精度,根据需要定义网络训练误差精度.误差公式是对训练出网络的输出层节点和实际的网络输出结果求平方差的和.
最大训练次数:
默认为10000次,根据需要调整,如果到达最大训练次数网络还未能达到目标精度,程序退出.
3.步长:
默认为0.01,由于采用变步长算法,一般不需人工设置.
4.输入层数目:
人工神经网络的输入层神经元的节点数目.
5.隐含层数目:
人工神经网络的隐含层神经元的节点数目.
6.输出层数目:
人工神经网络的输出层神经元的节点数目.
7.训练算法:
强烈建议选取Levenberg-Marquardt算法,该算法经过测试比较稳定.
8.激活函数:
不同的网络激活函数表现的性能不同,可根据实际情况选择.
9.样本数据的处理:
由于程序没有实现归一化功能, 因此用来训练的样本数据首先要归一化后才能进行训练.

Description: 众所周知，MATLAB是一个功能强大的数学软件，擅长于用矩阵运算完成各种数学功能。但是其程序需要在MATLAB环境下解释执行，效率不高。如果能将它强大的函数库用于C语言，利用C来编译执行，MATLAB将能发挥更大的作用。所以，MATLAB从5.0开始已经提供了与外部C/C++程序的应用程序接口，为利用C语言调用MATLAB的函数提供了可能。-As we all know, MATLAB is a powerful mathematical software, specializes in the completion of matrix operations with mathematical functions. However, its procedures need to explain the implementation of MATLAB environment, efficiency is not high. If it can be a powerful function library for C language, using C to compile the implementation, MATLAB will be able to play a greater role. Therefore, MATLAB has been provided from the 5.0 to start with the outside C/C++ Process application programming interface for the use of C language function calls MATLAB possible.
