2采用PCA对男女生样本数据中的身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征进行特征提取（自己设定选取的特征个数），并基于所得到的特征采用SVM设计男女生分类器，并计算模型预测性能（包含SE,SP,ACC和AUC ）。(2 using PCA for boys and girls in the sample data height, weight, like math, like literature, like sports, like common pattern recognition feature extraction feature 6 (wherein the number of the selected set itself), based on the obtained feature using SVM classifier design boys and girls, and calculating prediction performance model (including SE, SP, ACC and AUC).)

低通滤波器，对数据进行平滑，也叫做最小二乘法，Savitzky-Golay算法(a particular type of low-pass filter, well-adapted for data smoothing, and termed variously Savitzky-Golay, least-squares, or DISPO (Digital Smoothing Polynomial) filters. Rather than having their properties defined in the Fourier domain and then translated to the time domain, Savitzky-Golay filters derive directly from a particular formulation of the data smoothing problem in the time domain)

A simple code to find all the peaks in the radon space which are higher then the threshold given by the user , this code return the polaire coordinates (rho, theta) of every peak
