Inexact augmented lagrange multiplier method
Web11 jul. 2016 · The inexact augmented Lagrangian method (IALM) is used to optimize the proposed RCSR. The qualitative and quantitative experiments on synthetic datasets and real hyperspectral images demonstrate that the proposed RCSR is efficient for solving the hyperspectral SU problem compared with the other four state-of-the-art algorithms. … Webfor (2). To solve (3), the inexact Augmented Lagrangian method (iALM) is widely used [14, 15, 35], due to its cheap per iteration cost and its empirical success. Every (outer) iteration of iALM calls a solver to solve an intermediate augmented Lagrangian subproblem to near stationarity. The choices include first-order methods, such as the proximal
