说明：  BP神经网络分类器 程序有两种运行状态，一个是学习，另外一个是分类。在学习状态下，在Dos命令符下输入bp learn，便开始学习了，学习的结果放在weight.dat中；在工作状态下，在Dos命令符下输入bp work，便开始识别classfyme.dat中的数据了，识别完成后，结果放在results.dat中。在bp运行的任何一种状态下，都不能手工打开Weight.dat、Sample.dat、classfyme.dat、results.dat中的任何一种。~..~
(BP neural network classifiers have the two operations, a study, the other one is classified. In learning mode, in order website Dos importing bp learn, they start learning, the results of the study on weight.dat; in working condition, Dos website in order to import bp work, classfyme.dat began to identify the data, the identification is completed, The results were on results.dat. Bp in the operation of any state, it can not open Weight.dat hand, Sample.dat, classfyme.dat. results.dat of any kind. ~ ~ ..)
