Conjugate Gradient Iterative Hard Thresholding: Observed Noise Stability for Compressed Sensing
Conjugate gradient iterative hard thresholding (CGIHT) for compressed sensing combines the low per iteration computational cost of simple line search iterative hard thresholding algorithms with the improved convergence rates of more sophisticated sparse approximation algorithms. This paper shows tha...
