Abstract
We propose a priori accuracy estimates for low-rank matrix approximations that use just a small number of the rows and columns. This number is greater than the approximation rank, unlike the existing methods of pseudo-skeleton approximation. But the estimates are more accurate than previously known ones. This paper generalizes the results of [12,13].
