Outside of Spark, we'd recommend looking at IpOpt as an open source alternative for this: http://www.coin-or.org/projects/Ipopt.xml Blake On Wed, Oct 5, 2016 at 8:59 AM Robin East wrote: > The TFOCS package is announced here: > https://databricks.com/blog/2015/11/02/announcing-the-spark-tfocs

I would say no, at least not without a fair degree of algorithm writing experience. MLLib is primarily a set of machine learning algorithms, many of which are based on implementations of distributed optimisation procedures. The SAS routines you mention are optimisation routines which don't have

I'm not getting any support in this group, is the question not valid ? need someone to reply to this question, we have a huge dependency on SAS which we want to eliminate & want to know if spark can help. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/MLib-

Yes, we are using primarily these two algorithms. 1. Interior point trust-region line-search algorithm 2. Active-set trust-region line-search algorithm We are performing optimizations with constraints & thresholds etc. We are primarily using Lindo / SAS modules but want to get away from

Do you have any particular algorithms in mind? If you state the most common algorithms you use then it might stimulate the appropriate comments. > On 8 Sep 2016, at 05:04, nsareen wrote: > > Any answer to this question group ? > > > > -- > View this message in context: > http://apache-spa
