三层前馈神经网络的BP算法。程序具有以下功能:
(1) 允许选择各层节点数;
(2) 允许选用不同的学习率η;
(3) 能对权值进行初始化,初始化用[-1、1]区间的随机数;
(4)允许选用单极性和双极性两种不同Sigmoid型转移函数。

遗传算法(Genetic Algorithm)是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型,是一种通过模拟自然进化过程搜索最优解的方法,它最初由美国Michigan大学J.Holland教授于1975年首先提出来的,并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》,GA这个名称才逐渐为人所知,J.Holland教授所提出的GA通常为简单遗传算法(SGA),遗传算法简单源程序。-Genetic Algorit

实验将Iris花的数据集分为2组,每组各75个样本,每组中每种花各有25个样本。其中一组作为以上程序的训练样本,另外一组作为检验样本。为了方便训练,将3类花分别编号为1,2,3 。
使用这些数据训练一个4输入(分别对应4个特征),3输出(分别对应该样本属于某一品种的可能性大小)的前向网络。(The data set of Iris flower was divided into 2 groups, 75 samples in each group. Each group had 25 sam
