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).)

EM算法，在统计计算中，最大期望（EM）算法是在概率（probabilistic）模型中寻找参数最大似然估计或者最大后验估计的算法，其中概率模型依赖于无法观测的隐藏变量（Latent Variable）。(EM algorithm)
