[jira] [Updated] (OPENNLP-166) Remove slack parameter from GISModel

["Joern Kottmann (JIRA)" <ji...@apache.org>]

Joern Kottmann updated OPENNLP-166:
-----------------------------------

    Fix Version/s:     (was: 1.6.0)

Lets never do this change. The GIS model training is already outdated and should be replaced by the L-BFGS training. Either through our (currently broken) integration or by relying on a 3rd party solution like mallet.

> The support for a slack parameter inside the model should be removed from the GISModel class. Only old models which have been trained prior maxent 3.0 can have such a slack parameter or correction constant. The training code since maxent 3.0 always sets the correction constant to 1 to support backward compatibility with old models.
> Since the removal will break backward compatibility it should be aligned with the opennlp-ml redesign.
> The support to train models with a slack parameter has been completely removed in OPENNLP-165.
