Query: A Note on Randomized Element-wise Matrix Sparsification   Given a matrix A \in R^{m x n}, we present a randomized algorithm that
sparsifies A by retaining some of its elements by sampling them according to a
distribution that depends on both the square and the absolute value of the
entries. We combine the ideas of [4, 1] and provide an elementary proof of the
approximation accuracy of our algorithm following [4] without the truncation
step.
