PCA的步骤：
1 先将数据中心化；
2 求得的协方差矩阵；
3 求出协方差矩阵的特征值与特征向量；
4 将特征值与特征向量进行排序；
5 根据要降维的维数d’,求得要降维的投影方向；
6 求出降维后的数据；
(PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )
