"WebJul 2, 2024 · Subset selection for matrices is the task of extracting a column sub-matrix from a given matrix B ∈ ℝn×m with m > n such that the pseudoinverse of the sampled matrix has as small Frobenius or spectral norm as possible. In this paper, we consider a more general problem of subset selection for matrices that allows a block to be fixed at the … " - Twice ramanujan sparsifiers
