Description: 用GA直接训练BP网络的权重算法
主程序：gafault.m 它包括以下子程序：
1. BP网络初始化：nninit.m――给出P，T，R，S1，S2；
2. 适应值计算函数：gabpEval.m；
3．将遗传算法的编码解码为BP网络所对应的权值、阈值函数：gadecod.m；

Description: -----引入动量的算法
建立一个3层（含输入层）的BP神经网络，并对其进行训练
输入层不进行数据处理，隐含层激活函数为sigmod函数，输出层为线性函数
输入输出数据归一化到[-1,1]，数据在矩阵中按行向量表示
即x=[x11,x12 x21,x22 ... xp1,xp2] y=[y1 y2 ... yp] p为样本数 -The introduction of the algorithm ----- momentum to build a three-layer (including input layer) of the BP neural network, and its training of the input layer does not carry out data processing, the hidden layer activation function sigmod function, the output layer-line Sexual Function input and output data normalized to [-1,1], the data in the matrix row-vector representation or x = [x11, x12 x21, x22 ... xp1, xp2] y = [y1 y2 ... yp] p as the number of samples Platform: |

Description: 度信念网络是一个概率生成模型，与传统的判别模型的神经网络相对，生成模型是建立一个观察数据和标签之间的联合分布，对P(Observation|Label)和 P(Label|Observation)都做了评估，而判别模型仅仅而已评估了后者，也就是P(Label|Observation)。(The degree belief network is a probability generation model. Compared with the neural network of the traditional discriminant model, the generation model is to establish a joint distribution between observation data and labels, and to do both P (Observation|Label) and P (Label|Observation).The evaluation, and the discriminant model has only evaluated the latter, that is, P (Label|Observation).)
