一种l2,1范数最小化问题的算法研究
Algorithm study for l2, 1-norm minimization problems
摘要
Abstract
This paper proposes an augmented Lagrange function method to solve l2,1 - norm minimization problem. The convergence of the algorithm is easily followed in this paper. The numerical experiments illustrate that the proposed algorithm performs quite well.关键词
