Hero III" ], "categories": [ "stat.ML" ], "abstract": "Significant attention has been given to minimizing a penalized least squares criterion for estimating sparse solutions to large linear systems of equations. The penalty is responsible for inducing sparsity and the natural choice is the so-called $l_0$ norm. In this paper we develop a Momentumized Iterative Shrinkage Thresholding (MIST) algorithm for minimizing the resulting non-convex criterion and prove its convergence to a local minimizer. Simulations on large data sets show superior performance of the proposed method to other methods.", "revisions": [ { "version": "v1", "updated": "2014-09-25T09:28:54.000Z" } ], "analyses": { "keywords": [ "sparse linear regression", "large data sets", "large linear systems", "squares criterion", "estimating sparse solutions" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1409.7193M" } } }
