Re: MLib : Non Linear Optimization
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 SAS due to the cost, it would be really good to have these algorithms in Spark ML. Let me know if you need any more info, i can share some snippets if required.

Re: MLib : Non Linear Optimization
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 <nsar...@gmail.com> wrote: > > Any answer to this question group ? > > > > -- > View this message in context: > http://apache-spark-user-list.1001560.n3.nabble.com/MLib-Non-Linear-Optimization-tp27645p27676.html > Sent from the Apache Spark User List mailing list archive at Nabble.com. > > - > To unsubscribe e-mail: user-unsubscr...@spark.apache.org > - To unsubscribe e-mail: user-unsubscr...@spark.apache.org

MLib : Non Linear Optimization
I'm part of an Predictive Analytics marketing platform. We do a lot of Optimizations ( non linear ), currently using SAS / Lindo routines. I was going through Spark's MLib documentation & found it supports Linear Optimization, was wondering if it also supports Non Linear Optimization & if not, are there any plans to implement it in spark ? We really want to move away from SAS since it is a very expensive solution & does not work on a distributed scale. We want a solution which provides scalability & at the same time provide accurate results. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/MLib-Non-Linear-Optimization-tp27645.html Sent from the Apache Spark User List mailing list archive at Nabble.com. - To unsubscribe e-mail: user-unsubscr...@spark.apache.org
