Description copied from class: TransducerEvaluator

Evaluates a Tranducers on a given training, validation, and testing set. .

The default implementation calls the evaluator's test on the training, validation, and testing sets.

Overrides:

evaluate in class TransducerEvaluator

Parameters:

model - The transducer to evaluate.

finishedTraining - Whether training has finished. Evaluators can be set to always evaluate when training completes.

iteration - The current iteration

converged - Whether training has converged. Most evaluators ignore this.

cost - The current cost during training. Some evaluators may include this in the output.

training - The training set. If null, the argument is ignored.

validation - The validation set. If null, the argument is ignored.

testing - The testing set. If null, the argument is ignored.

Returns:

Whether training should continue.

test

public void test(Transducer model,
                 InstanceList data,
                 String description,
                 PrintStream viterbiOutputStream)
