Daniel Russ commented on OPENNLP-759:
-------------------------------------

Oh I forgot to mention.  I also checked that the Log Likelihoods are equal.  I 
could try to see if the parameters are exactly the same, but that might be 
difficult as equals() was overridden on GISModel.

> Speed up GIS training by saving Executor in the GISTrainer

>                 URL: https://issues.apache.org/jira/browse/OPENNLP-759
>             Project: OpenNLP
>          Issue Type: Improvement
>          Components: Machine Learning
>    Affects Versions: maxent-3.0.3
>            Reporter: Daniel Russ
>            Priority: Minor
>
> In GISTrainer.nextIteration(double) an ExecutorService is created and 
> shutdown.  I don't see a reason to create a ExecutorService for each 
> iteration.  
> If you create the ExecutorService in the TrainModels(int, dataindexer, Prior, 
> int, int) method you can save it as a field in GISTrainer or pass it as an 
> argument to findParameters(int, double).
> To test it out, I made a MyGIS and MyGISTrainer classes with the fixes.  
> There was a 5% speedup with 100 my dataset and 100 iterations of GIS.
> I would be happy to share the code with you.  (I can not share my data 
> though, sorry data-use agreements).
