WebConsider a random matrix A with i.i.d. entries. We show that the operator norm of A can be reduced to the optimal order O(p n) by zeroing out a small submatrix of A if and only if the entries have zero mean and nite variance. Moreover, we obtain an almost optimal dependence between the size of the removed submatrix and the resulting operator norm. WebMatrix or vector norm.
