## Feature
Recently an Adaptive-FISTA algorithm was introduced in https://www.earthdoc.org/content/papers/10.3997/2214-4609.202229010. This algorithm shows faster convergence for problems where the…

Hi,
would you mind provide the paper of this code?
thanks

Compressed sensing is now really fast with FISTA : https://github.com/MagneticResonanceImaging/MRIReco.jl/discussions/102#discussioncomment-3655548
But there is still an issue with accuracy (https:…

Hello, I am trying to perform FISTA reconstruction but the f_prox = f.proximal(gamma) line in proximal_gradient_solvers.py throws me an error because (I guess) my regularizer functional f falls into t…

All proximal method have stepsize adjustment steps that may cause instability in the parameter learning if the log-likelihood is sharply peaked. These parameters are `acceleration=True` and `stepsize

On a Intel Core i7-8565U CPU @ 1.80GHz × 8, the full test suite takes on average, 250s. I have noticed that tests are routinely failing in the GitHub CI, and I believe it may be because of this.

Both the `TotalVariation` function and `FGP_TV` from the CCPi regularisation toolkit solve the dual TV problem using the FISTA algorithm. In both cases, it is hardcoded and no acceleration is used. Si…
