Low Rank Vectorized Hankel Lift for Matrix Recovery via Fast Iterative Hard Thresholding
share
We propose a VHL-FIHT algorithm for matrix recovery in blind super-resolution problems in a nonconvex schema. Under certain assumptions, we show that VHL-FIHT converges to the ground truth with linear convergence rate. Numerical experiments are conducted to validate the linear convergence and effectiveness of the proposed approach.
