Websvd小结 SVD作为一个很基本的算法，在很多机器学习算法中都有它的身影，特别是在现在的大数据时代，由于SVD可以实现并行化，因此更是大展身手。 SVD的缺点是 分解出的矩阵解释性往往不强 ，有点黑盒子的味道，不过这不影响它的使用。 Web26 gen 2012 · z = a0 + a1*x + a2*y. Your matrix equation looks like this for N points: z (i) = a0 + a1*x (i) + a2*y (i) i = 1, N. The left hand side is an Nx1 vector; the right hand side is an Nx3 matrix multiplying an unknown vector that's 3x1. Multiply both sides by A (transpose) and you end up with a 3x3 matrix multiplying a 3x1 vector of unknown ... goodman\\u0027s american pie ludlow https://fantaskis.com
