[jira] [Updated] (SOLR-12631) Improvements to the harmonicFit
Stream Evaluator
[ https://issues.apache.org/jira/browse/SOLR-12631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Cassandra Targett updated SOLR-12631:
-------------------------------------
Component/s: streaming expressions
> Improvements to the harmonicFit Stream Evaluator
> ------------------------------------------------
>
> Key: SOLR-12631
> URL: https://issues.apache.org/jira/browse/SOLR-12631
> Project: Solr
> Issue Type: New Feature
> Components: streaming expressions
> Reporter: Joel Bernstein
> Priority: Major
>
> The current version of the *harmonicFit* Stream Evaluator is very hard to use. This ticket adds two important capabilities to the function:
> 1) Makes an initial guess internally so the fit to a sine wave is much better.
> 2) Returns a function that can used by the predict function.
