A Reduced Half Thresholding Algorithm

In this paper, a reduced half thresholding algorithm and its accelerated version, a reduced fast half thresholding algorithm, are proposed for solving large-scale L 1 / 2 -regularized problems. At each iteration, the large-scale original problem is reduced into a sequence of small-scale subproblems,...
