Thanks! Will try it out. From: Debasish Das [mailto:debasish.da...@gmail.com] Sent: Monday, December 08, 2014 5:13 PM To: Bui, Tri Cc: user@spark.apache.org Subject: Re: Learning rate or stepsize automation
Hi Bui, Please use BFGS based solvers...For BFGS you don't have to specify step size since the line search will find sufficient decrease each time... Regularization you still have to do grid search...it's not possible to automate that but on master you will find nice ways to automate grid search... Thanks.
