Maximum relative distance between real rank-two and rank-one tensors

Henrik Eisenmann, André Uschmajew

It is shown that the relative distance in Frobenius norm of a real symmetric order- tensor of rank two to its best rank-one approximation is upper bounded by $\sqrt{1-(1-1/d)^{d…

Riemannian thresholding methods for row-sparse and low-rank matrix recovery

Henrik Eisenmann, Felix Krahmer, Max Pfeffer +1

In this paper, we present modifications of the iterative hard thresholding (IHT) method for recovery of jointly row-sparse and low-rank matrices. In particular a Riemannian version…
