[jira] [Comment Edited] (SOLR-12019) Prepare Streaming Expressions
for machine learning functions
[ https://issues.apache.org/jira/browse/SOLR-12019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16650730#comment-16650730 ]

-----------------------------------------------------------------
I'm very close to starting work on the Smile integration. I'll be taking the same approach as with Apache Commons Math which is to add new functions with every release. So it will be a gradual ramp up. The big question is what to do first? I was thinking of adding some of the regression algorithms that are not in Apache Commons Math, such as Lasso and Ridge. Then adding classifiers (SVM, NaiveBayes etc...). I'm also interested in the plotting.

> Key: SOLR-12019
> URL: https://issues.apache.org/jira/browse/SOLR-12019
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: streaming expressions
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
> Fix For: 7.6, master (8.0)
>
>
> This ticket is to prepare the Streaming Expressions framework for the next phase of development which will focus on *machine learning*.
> Because this next phase will involve a large number of new functions it will be important to prepare the Streaming Expressions framework before getting started.
> There are three main goals of the ticket:
> 1) Refactoring of code and test cases to prepare for the new machine learning functions.
> 2) Improve the documentation of the current statistical functions and refactor the docs so they can support the new machine learning functions.
> 3) Integrate the [http://haifengl.github.io/smile/] libraries. Now that the *Apache Commons Math* integration is close to completion its time to start on the *Smile* machine learning integration.
