On the Restricted Isometry Property of Centered Self Khatri-Rao Products

In this work we establish the Restricted Isometry Property (RIP) of the centered column-wise self Khatri-Rao (KR) products of n\times N matrix with iid columns drawn either uniformly from a sphere or with iid sub-Gaussian entries. The self KR product is an n^2\times N-matrix which contains as columns the vectorized... Show more
