Matrix Completion and Low-Rank SVD via Fast Alternating Least Squares

9 Oct 2014 Trevor Hastie Rahul Mazumder Jason Lee Reza Zadeh

The matrix-completion problem has attracted a lot of attention, largely as a result of the celebrated Netflix competition. Two popular approaches for solving the problem are nuclear-norm-regularized matrix approximation (Candes and Tao, 2009, Mazumder, Hastie and Tibshirani, 2010), and maximum-margin matrix factorization (Srebro, Rennie and Jaakkola, 2005)...
