We introduce a new sparse recovery paradigm, called Normed Pursuits, where efficient algorithms from combinatorial and convex optimization interface for interpretable and model-based solutions. Synthetic and real data experiments illustrate that Normed Pursuits can significantly enhance the performance of both hard thresholding methods and convex solvers in sparse recovery.
