The randomized sparse Kaczmarz method was recently proposed to recover solutions of linear systems. In this work, we introduce a greedy variant the by employing sampling Kaczmarz-Motzkin method, and prove its convergence in expectation with respect Bregman distance noiseless noisy cases. This can be viewed as unification hence inherits merits these two methods. Numerically, report couple experi...

Capturing information behaviours and attitudes that occur in natural settings is a challenge. Observational methods are often intrusive or retrospective proxies, which may change behaviour misrepresent attitudes. Technology enables novel approaches to in-situ quantitative data collection but rarely explores qualitative reflections; informing researchers on what happened, not necessarily why. Re...
