[jira] [Created] (OPENNLP-703) Support parallel training for MAXENT_QN

Vinh Khuc created OPENNLP-703:
---------------------------------

             Summary: Support parallel training for MAXENT_QN
                 Key: OPENNLP-703
                 URL: https://issues.apache.org/jira/browse/OPENNLP-703
             Project: OpenNLP
          Issue Type: Improvement
          Components: Machine Learning
    Affects Versions: maxent-3.0.3, tools-1.5.3
            Reporter: Vinh Khuc
             Fix For: 1.6.0


Although the current L-BFGS trainer runs in a sequential manner, Maxent's objective function (i.e. the negative log-likelihood function) and its gradient can be computed in parallel. This JIRA will focus on improving the training time of MAXENT_QN.
