DTCostFunctionTrainer

class DTCostFunctionTrainer extends StateCostFunctionTrainer

The DTCostFunctionTrainer uses the our in-house decision tree implementation (org.allenai.nlpstack.parse.poly.decisiontree) to train a StateCostFunction. Training is triggered during construction, after which the .costFunction field contains the trained StateCostFunction.
