Description
This is the research data that accompanies the publication "Choose your path wisely: gradient descent in a Bregman distance framework". It contains code for all numerical examples given in the numerical results section of the associated publication. Note that the parallel MRI example and the classification example require additional external data. The corresponding URLs can be found in the associated publication
Version
