说明：  田纳西伊—斯特曼过程是一个基于真实化工生产过程模型。它的数据在许多领域被广泛研究和应用，比如优化控制、过程监控和故障诊断等。(The tennessee-sterman process is based on a real chemical process model.Its data is widely studied and applied in many fields, such as optimal control, process monitoring and fault diagnosis.)

汽车振动的频谱分析。很有意思，里面函数简单适合初学者。(Spectrum analysis of vehicle vibration. Very interesting, which a simple function suitable for beginners.)

测试样本集对每个模式进行加噪处理，噪声值为±0.1。若网络能对加噪模式进行正确分类，则认为该网络已训练完成。(Test sample set for each pattern plus noise processing, the noise value of ± 0.1. If the network can add noise to the model correctly classified, then that the network has completed the training.)

matlab实现的最小二乘法拟合程序，其中包含了数值结果分析过程。(matlab implementation of least-squares fitting program, which includes the analysis of the numerical results.)
