Journal of Applied Mathematics, 2013, vol. 2013, 1-5

Abstract:

We propose a subspace embedding method via Fast Cauchy Transform (FCT) in norm. It is motivated by and complements the work of the subspace embedding method in norm, for all except , by K. L. Clarkson (ACM-SIAM, 2013). Unlike the traditionally used orthogonal basis in Johnson-Lindenstrauss (JL) embedding, we employ the well-conditioned basis in norm to obtain concentration property of FCT in norm.
