英文摘要: Up to now, with the increasing “need” and “dependence” of data, and the rapid development of technologies for sampling and storing data, high dimension data have emerged, such as remote sensing data, biological data, network data and market data. And those data are often appeared in the form of matrix. Therefore, how to deal with the high dimensional data in matrix, establish the new computational models and develop the effective algorithms are the urgent problems for computation science, information science and applied mathematics. This project firstly designs some sparse regularization algorithms for matrix recovery, derives the approximate optimal solution, and estimates the convergence speed with optimization algorithms, numerical approximation, statistical learning theory, matrix analysis, signal processing and other related theories and methods. Furthermore, it creates the new path to study the sparse regularization algorithms for matrix recovery, stability analysis and error analysis from the theory of statistical learning. Finally, it applies those proposed algorithms to high dimension image completion and high resolution image recovery. The completion of this project can provide the theoretical basis and algorithms for solving many practical problems, enrich computational models and basic algorithms in
