Error bound of local minima and KL property of exponent 1/2 for squared F-norm regularized factorization

11 Nov 2019Ting TaoShaohua PanShujun Bi

This paper is concerned with the squared F(robenius)-norm regularized factorization form for noisy low-rank matrix recovery problems. Under a suitable assumption on the restricted condition number of the Hessian matrix of the loss function, we establish an error bound to the true matrix for those local minima whose ranks are not more than the rank of the true matrix...
