Abstract

© 2018 IEEE. In this work we transfer several recent acceleration techniques for the FISTA algorithm for composite convex opti- mization to the context of problems amenable to be solved by Block Coordinate Descent and, in particular, we show how these improvements can be used to speed up the training of the Sparse Group Lasso model. Experiments in several real life datasets illustrate how the proposed method can outperform the state of the art approach in terms of both the number of inner FISTA and outer block iterations required and, more importantly, the number of function and gradient evaluations needed to achieve a certain precision.
