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. Webproposed algorithm for two scenarios: matrix completion under Assumption 1, and matrix comple-tion under both Assumption 1 and Assumption 2. Furthermore, we will assume that Assumption 1 always holds, and that the rank k, the condition number ˙ 1 =˙ k, and the incoherence parameter 0 of the matrix Mare bounded from above by a constant, as n!1.
