代码说明:

代码工作原理:训练数据预测数据提取及归一化处理,加载四类信号四个特征信号矩阵合成一个矩阵,随机提取1500个样本为训练样本,500个样本为预测样本。权值初始化,网络训练,网络预测输出,隐含层输出, 输出层输出,权值阀值修正计算误差,计算权值变化率,特征信号分类,隐含层输出,结果分析,根据网络输出找出数据属于哪类,画出预测种类和实际种类的分类图,显示正确率。  

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • Challenge_Data
    故障预测与健康管理数据PHM,数据格式为txt,希望对有需要的同志有帮助。英文描述建议大家看看,说不定会有帮助。(5. PHM08 Challenge data set the data challenge competition held at the 1st international conference on Prognostics and Health Management (PHM08) is being made publicly available. The dataset is similar to the one posted above (see Turbofan engine degradation simulation data set) except the true RUL values are not revealed. Users are expected to develop their algorithms using training and test sets provided in the package. The set is in text format and has been zipped including a readme file. Please cite: A. Saxena and K. Goebel (2008). PHM08 Challenge Data Set )
