Abstract: In several applications, the data consists of an m \Theta n matrix A and it is of interest to find an
approximation D of a specified rank k to A where, k is much smaller than m and n. Traditional
methods like the Singular Value Decomposition (SVD) help us find the "best" such approximation.
However, these methods take time polynomial in m;n which is often too prohibitive.
In this paper, we develop an algorithm which is qualitatively faster provided we may sample
the entries of the matrix... (Update)
