Subject [GitHub] spark pull request: [SPARK-1543][MLlib] Add ADMM for solving Lasso...
Date Mon, 05 May 2014 18:31:55 GMT
Github user debasish83 commented on the pull request:
    Depends how you solve L1 with lbfgs...
    OWL-QN for L1 is definitely a solution...
    You can also replace L1 as soft-max and but then you have to be careful
    with the schedule of soft-max smoothness....
    I think just pick OWL-QN for L1 (as it is implemented in breeze) and
    comparing against ADMM will be good....
