Tight bounds for the subspace sketch problem with applications
In the subspace sketch problem one is given an n × d matrix A with O(log(nd)) bit entries, and would like to compress it in an arbitrary way to build a small space data structure Qp, so that for any given x ∊ ℝd, with probability at least 2/3, one has Qp(x) = (1 ± ∊ )|| Ax||p, where p ≥ 0 and the ra...
