Implement the K nearest neighbor algorithm by your own instead of using available software. 2. Use K-fold cross validation to generate training and testing datasets. You should try different K values (3~8) to see how they affect your result. 3. Train the classifier using your training dataset, and test the classifier using your testing dataset. 4. Repeat the experiment (Step 2 and Step 3) 30 times. For each time, you need to record the training data accuracy and testing data accuracy. Finally, you can obtain the average training data accuracy and average testing data accuracy.

this is an important code.

用双线性变换法设计BW型或CB型的不同类型（低通、高通、带通）的数字滤波器求出系统的单位脉冲响应h(n)(Bilinear transform design BW or CB-type (low pass, high pass, band-pass) digital filter to find the system unit impulse response h (n))

在计算机科学与技术中，地球移动距离(EMD)是一种在D区域两个概率分布距离的度量，就是被熟知的Wasserstein度量标准。不正式的说，如果两个分布被看作在D区域上两种不同方式堆积一定数量的山堆，那么EMD就是把一堆变成另一堆所需要移动单位小块最小的距离之和。(In computer science, the earth mover s distance (EMD) is a measure of the distance between two probability distributions over a region D. In mathematics, this is known as the Wasserstein metric.)
