A Subspace Embedding Method in L2 Norm via Fast Cauchy Transform
We propose a subspace embedding method via Fast Cauchy Transform (FCT) in L2 norm. It is motivated by and complements the work of the subspace embedding method in Lp norm, for all p∈[1,∞] except p = 2, by K. L. Clarkson (ACM-SIAM, 2013). Unlike the traditionally used orthogonal basis in Johnson-Lin...
