Pcnn神经网络筛选特征因子代码，pca预处理代码，特征因子整合代码，等等，都是好东西啊(Pcnn neural network filter characteristic factor code, pca pretreatment code, characteristic factor integration code, etc., are all good things ah)

产生不同频率、幅度的正弦波信号，叠加后，设计低通、带通滤波器进行正弦信号的谱分析及提取。(The sine wave signals with different frequencies and amplitudes are generated. After superposition, the low-pass and bandpass filters are designed for spectrum analysis and extraction of sinusoidal signals.)

说明：  梯度下降法是一個一階最佳化算法，通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值，必須向函數上當前點對應梯度（或者是近似梯度）的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索，則會接近函數的局部極大值點；這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)
