Faster and Still Safe: Combining Screening Techniques and Structured Dictionaries to Accelerate the Lasso

ICASSP 2018accepted

Accelerating the solution of the Lasso problem becomes crucial when scaling to very high dimensional data. In this paper, we propose a way to combine two existing acceleration techniques: safe screening tests, which simplify the problem by eliminating useless dictionary atoms; and the use of structu…
