人工神经网络BP算法
1、动态改变学习速率
2、加入动量项
3、运用了Matcom4.5的矩阵运算库(可免费下载,头文件matlib.h),
方便矩阵运算,当然,也可自己写矩阵类
4、可暂停运算
5、可将网络以文件的形式保存、恢复-Artificial neural network BP algorithm 1, the dynamic change learning rate 2, adding momentum of 3, using the matrix calculation Matcom4.5 library (can be downloaded free of charge, the first document matlib.h), facilitate the matrix calculation, of course, can also write their own matrix Class 4, may be suspended by the operator 5, may be the form of network to the preservation, restoration

仿真1:首先把网络温度参数T固定在100,按工作规则共进行1000次状态更新,把这1000次状态转移中网络中的各个状态出现的次数Si(i=1,2,…,16)记录
仿真1:首先把网络温度参数T固定在100,按工作规则共进行1000次状态更新,把这1000次状态转移中网络中的各个状态出现的次数Si(i=1,2,…,16)记录下来 按下式计算各个状态出现的实际频率: Pi=Si/∑i=1,NSi=Si/M 同时按照Bo1tzmann分布计算网络各个状态出现概率的理论值: Q(Ei)=(1/Z)exp(-Ei/T) 仿真2:实施降温方案,重新计算 采用快速降温方案:T(t)= T0/(1+t) T从1000降到0.01,按工作规则更新网络状态 当T=0.01时结束降温,再让T保持在0.01进行1000次状态转移,比较两种概率-a simulation : First of all network parameters temperature T fixed at 100 and, according to the rules for a total of 1000 to update the state, this state of the 1000 network transfer of all states for the number of Si (i = 1, 2, ..., 16) all recorded determined by the formula state-of the actual frequency : Pi = Si/i = 1, NSi = Si/M in accordance with Bo1tzmann distributed computing network of states all probability the theoretical value : Q (Ei) = (1/Z) exp (- Ei/T) Simulation 2 : implementation of cooling, re-using rapid cooling programs : T (t) = T0/(1 t) T dropped to 0.01 from 1000 and, according to the rules updated network state when T = 0.01 at the end of cooling, let T at 0.01 for the 1000 state tran
