Low-rank approximation - Wikipedia
Nettet9. jan. 2012 · An optimal low rank approximation can be easily computed using the SVD of A in O (mn^2 ). Using random projections we show how to achieve an ”almost optimal” low rank pproximation in O (mn log (n)). Matlab code from a blog: clear % preparing the problem % trying to find a low approximation to A, an m x n matrix % where m >= n m … NettetLow rank approximation o ers a reduction of the problem size which can enable the computational solution of problems which would otherwise be inaccessible. It does however not come without new challenges. Since the manifold M r is not linear, (4) is a non-linear problem even if F is linear.
