ISODATA聚类算法，内附详细注解，使用了Iris数据集。ISODATA是一种常用的聚类算法之一。(ISODATA clustering algorithm, containing detailed notes, using the Iris data set. ISODATA clustering algorithm is a common one.)

EOF 计算时空场X的EOF前10个模态.每个空间型的方差解释率 对应的时间系数 (特征向量)的特征值(EOF space field X, calculating the first 10 EOF modes. Each space type of variance explained by the corresponding time coefficients (eigenvectors) and eigenvalues)

蒙特卡洛实验，得出曲线为检测性能曲线，为取不同信噪比下的PD与SNR的关系。(The Monte Carlo experiment shows that the curve is the detection performance curve, and the relationship between PD and SNR at different SNR is obtained.)

把HHT和神经网络结合起来，识别出是否故障。对于HHT变换，这里用到的是它的IMF分解，然后用能量理论来判别哪些模组是虚假分量，哪些是是真实分量。对于EMD分解后的谱进行特征提取 ，利用的理论基础就是模糊熵。计算出真实 分量的模糊熵，作为输入层；输出层为两个神经元，为0（故障 ）1（正常 （正常 ）判别该信号是否出现故障。(The combination of HHT and neural network to identify whether the fault. For the HHT transform, here is the use of its IMF decomposition, and then use the energy theory to determine which module is false, which is true component. The theoretical basis for the feature extraction of the spectrum after EMD decomposition is fuzzy entropy. The fuzzy entropy of the real component is calculated, as the input layer, the output layer is two neurons, which is 0 (fault) 1 (normal) to determine whether the signal is faulty.)
