Matrix Multiplication Using Incoherent Optical Techniques

Various matrix completion algorithms have been proposed. These includes convex relaxation-based algorithm, gradient-based algorithm, and alternating minimization-based algorithm. The rank minimization problem is NP-hard. One approach, proposed by Candès and Recht, is to form a convex relaxation of the problem and minimize the nuclear norm (which gives the sum of the singular values of ) instead of (which counts the number of non zero singular values of ).
