Solver and Software

STELA

  • STELA is a solver for sparsity regularized least square problems (LASSO).
  • Its key features are best-response-based update direction and exact-line-search-based stepsize, both of which have closed-form expressions.
  • It has several notable advantages, namely, fast convergence, easy implementation and excellent scalability.
  • Theoretical analysis is presented here (opens in new tab) .
  • Matlab code is available for academic uses here.
