Use the DAL Elastic Net Algorithm

max_it = 100,

eta_multiplier = 2,
eta_start_conservative = 0.01,
eta_start_aggressive = 1,
lambda_relchange_aggressive = 0.25
)
max_it |
maximum number of (outer) iterations. |
max_inner_it |
maximum number of (inner) iterations in each outer iteration. |
eta_multiplier |
multiplier for the barrier parameter. In each iteration, the barrier must be more restrictive (i.e., the multiplier must be > 1). |
eta_start_conservative |
conservative initial barrier parameter. This is used if the previous penalty is undefined or too far away. |
eta_start_aggressive |
aggressive initial barrier parameter. This is used if the previous penalty is close. |
lambda_relchange_aggressive |
how close must the lambda parameter from the previous penalty term be to use an aggressive initial barrier parameter (i.e., what constitutes "too far"). |
