magni.cs.reconstruction.amp package¶
Subpackage providing implementations of Approximate Message Passing (AMP).
Routine listings¶
- config
- Configger providing configuration options for this subpackage.
- threshold_operator
- Module providing AMP threshold operators.
- run(y, A)
- Run the AMP reconstruction algorithm.
- stop_criterion
- Module providing AMP stop criteria.
- util
- Module providing AMP utilities.
Notes
An implementation of the Donoho, Maleki, Montanari (DMM) AMP using soft thresholding from [1] is provided with threshold options as specified in [2].
The implementation allows for using custom thresholding functions and stop criteria.
