Epic structured SVM/Perceptron

[Omid]

Hi,

Can you give illustrate example an example of using Epic structured SVM or Perceptron? 

Thanks,

[David Hall]

I never finished Structured SVM, so that's out.

StructuredPerceptron (I'm not 100% sure I ever debugged it): 

1) Make a Model (e.g. a CRFModel by making a TaggedSequenceModelFactory)

2) Wrap the model in a OneBestModelAdaptor

3) new StructuredPerceptron(oneBestModel).train(data)

Thanks, is there any reason that you didn't keep the generality in TaggedSequenceModelFactory? because instead of type W, you use String ... So words should be alwayse string in makeModel(data).

Um, laziness, mostly.  You can make your own CRFModel however you want. The TaggedSequenceModelFactory is a convenience class that is currently inconveniently specialized to Strings...
