中文说明：
我们将使用小波包分解来提取信号的频带信息，并计算每个频带的能量。接下来，我们将使用libsvm和ANN分类器来对这些频带能量进行分类和预测。这个方法将帮助我们更好地理解信号的特征，并为我们提供更准确的分类结果。
English Description：
We will use wavelet packet decomposition to extract the frequency band information of the signal and calculate the energy of each frequency band. Next, we will use libSVM and ANN classifiers to classify and predict the energy of these frequency bands. This method will help us better understand the characteristics of signals and provide us with more accurate classification results
