Contains code for computing empirically the mean-squared error of Lasso methods.
- Algorithms for solving ell1 problems
iPython notebook that contains an AMP algorithm, and some other methods.
- Empirical Lasso MSE
iPython notebook that uses spgl1
to compute the empirical MSE for several
parameter settings in the underdetermined normal-random case.
- jsonWriteDict
writes a dictionary containing numpy arrays to an easy-to-read json file.
- pdmse
contains methods for computing the mean-squared error of proximal denoising solutions.
- ProxDenoisSPGL1HistData
contains code that uses both pdmse and jsonWriteDict to compute the mean-squared error in the proximal denoising case a large number of times for several signal dimensions; stores the result in a json file.
