WebDec 28, 2024 · 第一种比较经典的算法就是特征脸法，本质上其实就是PCA降维，这种算法的基本思路是，把二维的图像先灰度化，转化为一通道的图像，之后再把它首尾相接转化为一个列向量，假设图像大小是20*20的，那么这个向量就是400维，理论上讲组织成一个向量，就可以应用任何机器学习算法了，但是维度太高算法复杂度也会随之升高，所以需要使 … Web其实就是与其他的变化最不相符 eigValInd = eigValInd[:-(topNfeat+1):-1] #反转 redEigVects = eigVects[:,eigValInd] # lowDDataMat = meanRemoved * redEigVects #映射 reconMat = (lowDDataMat * redEigVects.T) + meanVals return lowDDataMat, reconMat. 主成分分析法的数学原理我们可以简单地了解一下就可以了: 找到 ...
