How can I use 10 folds cross validation in Stanford relation extraction (custom relation extraction model)

Question

How can I use 10 folds cross validation in Stanford relation extraction. I created a custom relation extraction model ,and I need to evaluate this model

Answer 1

You may find CrossValidator useful, if you're using the Stanford classifier. Taking a dataset, you can do something like:

Dataset dataset = ...;
double aveAccuracy = new CrossValidator(dataset, 10).computeAverage( (train, dev) -> {
  // train on |train| for the fold
  LinearClassifier classifier = ...;
  // evaluate on |dev| for the fold
  return classifier.evaluateAccuracy(dev);
});
