  • Patent number: 12141037
    Abstract: A method for performing data recovering operation is provided. The method includes: identifying a plurality of first values and a plurality of first indexes of a plurality of first entries of an incomplete matrix in a received object data, and one or more second values and one or more second indexes of one or more second entries of the incomplete matrix; inputting the first values, the first indexes, a preset first parameter, a preset second parameter and a preset third parameter into an analysis model using Adaptive Rank-One Matrix Completion (AROMC) algorithm; and obtaining a recovered complete matrix corresponding to the incomplete matrix from the analysis model, so as to obtain optimized one or more second values of the second entries, wherein the optimized one or more second values are determined as original values of the second entries, such that the incomplete matrix is recovered to the recovered complete matrix.

  • Publication number: 20240193226
    Abstract: A method for performing a robust low-rank matrix recovery using Hybrid Ordinary-Welsch Function is provided. The method includes: receiving object data, wherein the object data comprises an incomplete matrix; identifying a plurality of first values and a plurality of first indexes of a plurality of first entries of the incomplete matrix, and one or more second values and one or more second indexes of one or more second entries of the incomplete matrix according to the object data; inputting the first values (X106 ), the first indexes(?), a rank r, the second indexes, a preset first parameter (?1), a preset second parameter (?2), a first maximum iteration number (I1), a second maximum iteration number (?2), a first tolerance parameter (?1) and a second tolerance parameter (?2) into an executed analysis model using HOW algorithm; and obtaining a recovered complete matrix corresponding to the incomplete matrix from the analysis model.

  • Patent number: 10579702
    Abstract: The present disclosure relates to methods and systems for signal processing using coordinate descent technique for solving technical implementation problems that are expressed as unit-modulus least squares (UMLS) and unit-modulus quadratic program (UMQP) problems. Embodiments provide for iteratively minimizing an objective function of a signal vector associated with a UMLS/UMQP problem expression over a set of coordinates of the signal vector to a convergence point. The objective function is minimized with respect to a vector element corresponding to a selected coordinate index, while other vector elements that do not correspond to the selected coordinate index are fixed. Accordingly, at each iteration, minimizing the objective function involves a solution to a one-dimensional univariate quadratic minimization. Embodiments also provide various coordinate index selection rules that include a cyclic CD rule (CCD), a randomized CD rule (RCD), randomly permuted CD rule (RPCD), and a greedy CD rule (CCD).
