[…] as:, the convex problems in equation (12) can be efficiently solved by plenty of tools such as the l1-magic software package (candes and romberg, ), the gpsr package (figueiredo et al., ) and the l1-homotopy package (asif and romberg, )., finally, the identification of the test sample y can be employed using equation (5) as follows:, where the {·}l represents the l-th element in the brace., […]

[…] mit database [] and fei database []. our approach is compared with several other algorithms including the src [] and ssrc [] under the same conditions whereby all methods are optimized by using the l1-homotopy [,] algorithm with the regularization parameter λ =0.005. all experiments are done on a pc with an intel i7 2600 cpu and 16 g ram using a single thread. the implementation of all methods […]
