matlab实现此过程的最速下降算法。
这个Matlab程序实现最速下降算法。最速下降法是一种最基本的算法,它在最优化方法中占有重要地位.最速下降法的优点是工作量小,存储变量较少,初始点要求不高;缺点是收敛慢,最速下降法适用于寻优过程的前期迭代或作为间插步骤,当接近极值点时,宜选用别种收敛快的算法.

BP网络的C/C++实现,含有详细代码和例子,适合初学者
应用背景人工神经网络(ANN)中关于反向传播算法的内容,相比单个感知器而言,采用多层网络的反向传播算法能表示出更多种类的非线性曲面,整个神经网络可以分成三层:输入层,隐藏层,输出层,通过加权线性变换,层与层之间的传递,最终得到输入层的实数值。关键技术
本人根据附件里面的文章编写的反向传播算法代码,里面含有详细的代码注释和文章例子, 可以让初学者深刻理解反向传播算法,适合初学者学习。给出BP算法训练的例子,对单个样本的训练的情况进行编写和验证。
//输入层到隐层的过程
float fNetj[m];
for (int j= 0;j < m; j++){
fNetj[j] = fTheta[n][j]; //这里权值矩阵最后一列是偏置,偏置×1还是偏置,所以直接加上,
//后面就不用乘了
for(int i = 0;i < n; i++){ //得到netj 的值 netj= X^V
fNetj[j] +=fInputdata[i]*fTheta[i][j];
}
fMidResult[j] = 1/(1 + exp(-fNetj[j]));
//cout

apriori算法
该算法的基本思想是:首先找出所有的频集,这些项集出现的频繁性至少和预定义的最小支持度一样。然后由频集产生强关联规则,这些规则必须满足最小支持度和最小可信度。然后使用第1步找到的频集产生期望的规则,产生只包含集合的项的所有规则,其中每一条规则的右部只有一项,这里采用的是中规则的定义。一旦这些规则被生成,那么只有那些大于用户给定的最小可信度的规则才被留下来。为了生成所有频集,使用了递归的方法。
