WebSep 13, 2024 · Matrix completion aims to recover a matrix from a small subset of its entries. The matrix completion problem is prevalent in many applications, including computer vision, collaborative filtering, sensor network localization, learning and content analytics, rank aggregation, and manifold learning.
WebIn this paper we consider a convex optimization formulation to splitting the specified matrix into its components by minimizing a linear combination of the ℓ 1 norm and the nuclear … WebMay 12, 2024 · We determine an asymptotically exact, matrix-dependent, non-universal detection threshold above which reliable, statistically optimal matrix recovery using a new, universal data-driven matrix-completion algorithm is possible. Averaging the left and right eigenvectors provably improves the recovered matrix but not the detection threshold.
