A Deterministic Theory of Low Rank Matrix Completion

WebWe motivate our algorithm by its theoretical analysis for the simplified case of a rank 1 matrix. Empirically, R2RILS is able to recover ill-conditioned low rank matrices from very few observations---near the information limit---and it is stable to additive noise. WebJun 12, 2013 · Matrix completion, i.e., the exact and provable recovery of a low-rank matrix from a small subset of its elements, is currently only known to be possible if the matrix satisfies a restrictive structural constraint---known as {\\em incoherence}---on its row and column spaces. In these cases, the subset of elements is sampled uniformly at random. …
